Patent Description:
Generally speaking, a side view mirror is externally mounted on a motor vehicle adjacent to vehicle doors for enabling a driver to see beside and/or behind the motor vehicle. An angle of the side view mirror is manually or remotely adjustable so as to provide adequate coverage for a driver. A side view mirror may be electrically heated and may be dimmable. Although the field of view of a side view mirror is typically adjustable by the driver of the vehicle by changing the position and/or orientation of the side view mirror, the field of view is typically set and left in place regardless of driving conditions. As a result, turn collisions with objects while a motor vehicle is turning might happen if the field of view of the side view mirror is not set correctly for actual driving conditions. The closest prior art document <CIT> discloses a method of operating a computer system of a motor vehicle, the method comprising: receiving, via a processor device of the computer system, camera image data captured by a side view camera of the motor vehicle, the camera image data comprising a camera field of view; displaying display image data on a display screen, the display image data comprising a display field of view of at least a portion of the camera field of view of the camera image data; and adjusting the display field of view during a turning operation of the motor vehicle.

According to a first aspect of the disclosure, a method of operating a computer system of a motor vehicle includes receiving, via a processor device of the computer system, camera image data captured by a side view camera of the motor vehicle, the camera image data comprising a camera field of view, displaying display image data on a display screen, the display image data comprising a display field of view of at least a portion of the camera field of view of the camera image data, and adjusting the display field of view during a turning operation of the motor vehicle based on a lift axle position of at least one lift axle of the motor vehicle. The first aspect of the disclosure may seek to provide a side view image to an operator of the vehicle during a turning operation that is adjusted based on a turning radius of the moto vehicle. A technical benefit may include improved operation of the motor vehicle and a reduced likelihood of collision.

According to an example, adjusting the display field of view maintains an end corner of the motor vehicle within the display field of view during the turning operation. A technical benefit may include improved operation of the motor vehicle and a reduced likelihood of collision.

According to an example, adjusting the display field of view comprises at least one of digitally resizing, digitally panning, and digitally rotating the display field of view within the camera field of view. A technical benefit may include enabling the image displayed to the operator to be adjusted without physically moving the camera.

According to an example, adjusting the display field of view comprises mechanically adjusting the side view camera based on the lift axle position of the at least one lift axle. A technical benefit may include enabling the camera to capture a larger field of view than would be possible with a fixed position.

Mechanically adjusting the side view camera may comprise panning the side view camera. A technical benefit may include enabling the camera to capture a wider field of view than would be possible with a fixed position.

According to an example, adjusting the display field of view based on the lift axle position is performed by adjusting, via the processor device, the display field of view based on a rear turning point of the motor vehicle. A technical benefit may include enabling adjustment of the display field of view based on an actual location of a rear corner of the motor vehicle.

A center point between fixed axle points of at least two fixed axles of the motor vehicle may be designated as the rear turning point in response to the lift axle position being in a raised position. A technical benefit may include enabling adjustment of the display field of view based on an actual turning radius of the motor vehicle.

According to an example, adjusting the display field of view based on the lift axle position is performed by adjusting, via the processor device, the display field of view based on a turning radius of the motor vehicle. A technical benefit may include enabling adjustment of the display field of view based on an actual turning radius of the motor vehicle.

According to an example, adjusting the display field of view based on the lift axle position is performed by adjusting, via the processor device, the display field of view based on a distance between a front axle point of a front axle of the motor vehicle and a rear turning point of the motor vehicle. The distance may be combined from a front distance between an intermediate axle point of an intermediate axle of the motor vehicle and the front axle point and a rear distance between a hitching point of a hitch of the motor vehicle and the rear turning point. A technical benefit may include improved operation of the motor vehicle and a reduced likelihood of collision.

The front axle and the intermediate axle may be mounted on a towing vehicular part of the motor vehicle, and the at least one lift axle may be mounted on a towed vehicular part of the motor vehicle. According to an example, adjusting the display field of view based on the lift axle position is performed by adjusting, via the processor device, the display field of view based on the distance and a relative angle between the towing vehicular part and the towed vehicular part. A technical benefit may include enabling adjustment of the display field of view based on the presence of a towed vehicular part.

The method may further comprise sensing the lift axle position by a lift axle position sensing device of the computer system. The lift axle position may be determined by a wheel position of at least one wheel of the motor vehicle sensed by a wheel position sensing device of the computer system, and the at least one wheel may be connected with the at least one lift axle. A technical benefit may include automatically determining the lift axle position.

According to an example, the lift axle position is determined by a wheel rotation status of at least one wheel sensed by a wheel rotation sensing device of the computer system, and the at least one wheel is connected with the at least one lift axle. A technical benefit may include automatically determining the lift axle position without need of a lift axle position sensor.

A method of operating a computer system of a motor vehicle according to further examples includes determining, via a processor device, a lift axle position of at least one lift axle of the motor vehicle, adjusting, via the processor device, an image captured by a side view camera of the vehicle during a turning operation of the motor vehicle based on the lift axle position of at least one lift axle of the motor vehicle, and displaying the adjusted image on a display screen of the vehicle. A technical benefit may include improved operation of the motor vehicle and a reduced likelihood of collision.

According to an example, adjusting the image comprises adjusting, via the processor device, at least one of an azimuth angle and an altitude angle of the side view camera.

According to an example, adjusting the image comprises applying, via the processor device, at least one of digitally resizing (132a), digitally panning (132b) and digitally rotating (132c) at least a portion of the image captured by the side view camera. A technical benefit may include enabling the image displayed to the operator to be adjusted without physically moving the camera.

According to an example, adjusting the image comprises mechanically panning the side view camera. A technical benefit may include enabling the camera to capture a larger field of view than would be possible with a fixed position.

According to an example, adjusting the image is performed to maintain an end corner of the motor vehicle falling within a field of view of a data region of the image that is displayed on the display screen during the turning operation. A technical benefit may include improved operation of the motor vehicle and a reduced likelihood of collision.

A computer program product of operating a display system of a motor vehicle is provided. The computer program product comprises a non-transitory computer readable medium, a program code, and the program code being stored in the non-transitory computer readable medium that when executed a processor device causes the display system to perform the method described above.

A technical benefit may include updating captured visual media data by adjusting a field of view of a side view camera of a display system based on a lift axle position during a vehicle turning operation so that an end of the vehicle remains in the operator's view during the turning operation.

The accompanying drawings, which are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this application, illustrate certain non-limiting examples. Like numbers in the figures refer to like operations and like components. In the drawings:.

As noted above, the field of view of a side view mirror is typically set by a driver and left in place regardless of driving conditions. For example, a truck may have a different overall length and/or a different turning radius depending on whether it is attached to a trailer. Moreover, even for the same trailer, the turning radius of a truck can change when a lift axle of the truck is lifted. If a side view mirror field of view is set for a turning radius that is based on a rear axle being lifted, the selected field of view may not be appropriate for the turning radius of the truck when the lift axle is lowered.

Right-hand turn collisions or left-hand turn collisions with motorists and pedestrians or other vehicles or objects might be avoided while a motor vehicle is turning by automatically tracking and keeping in view the end corner and/or the lateral side of the motor vehicle.

According to some examples, a method of operating a display system <NUM> of a motor vehicle <NUM> is provided. The method is described with reference to <FIG>. According to some examples, as illustrated in <FIG>, a display system <NUM> may include an electronic control unit (ECU) <NUM>, a side view camera <NUM>, a display screen <NUM>, a lift axle position sensing device <NUM>, a data storage device <NUM>, a wheel position/rotation sensing device <NUM>.

The side view camera <NUM>, the display screen <NUM>, the lift axle position sensing device <NUM>, the data storage device <NUM>, and the wheel position/rotation sensing device <NUM> may each be electrically coupled with the ECU <NUM>. The lift axle position sensing device <NUM> and the wheel position/rotation sensing device <NUM> may each be a sensor or an image processor. The ECU <NUM>, the display screen <NUM> and the data storage device <NUM> may be mounted inside, for instance, a cab of the motor vehicle <NUM>. The side view camera <NUM> may be mounted outside, for instance, a cab of the motor vehicle <NUM>, and may be located adjacent to a driver window or a passenger window. The display system <NUM> may be a Camera Monitor System (CMS) which may be used for an Advanced Driver Assistance Systems (ADAS) or self-driving systems.

As shown in <FIG> and <FIG>, according to some examples, the motor vehicle <NUM>, such as a commercial vehicle, may include at least one lift axle <NUM>, a front axle <NUM>, at least one fixed axle <NUM> and at least one wheel <NUM>. The lift axle <NUM> may be used to manage more efficient tires wear out and load handling. For example, a trailer may have four axles, among which one axle may be raised relative to the other axles such that the tires are lifted from the ground while the remaining three axles may be in contact with ground. There may be some major advantages by using a lift axle for a trailer, such as extending the life of tires and brake shoes, reducing rolling resistance and improving fuel efficiency, and reducing damages to the road surface. The lift axle raising and lowering function may be achieved via compressed air used by a trailer or other similar device/mechanism.

Brief reference is made to <FIG>, which illustrates a field of view <NUM> of an image captured by a side view camera <NUM> (also referred to as the field of view <NUM> of the side view camera <NUM> or simply the camera field of view <NUM>). The camera field of view <NUM> may be represented in the form of two-dimensional digital image data that is captured by the side view camera <NUM>. A display image having a display field of view that corresponds to the camera field of view <NUM> may be displayed to an operator of the motor vehicle on a display screen <NUM>. In some examples, only a portion of the camera field of view <NUM>, represented by a two-dimensional data region <NUM> that corresponds to a sub-region of the field of view <NUM>, may be displayed to the operator on the display screen <NUM>.

Accordingly, the side view camera <NUM> has a camera field of view <NUM>, and the display screen <NUM> has a display field of view <NUM> that may be the same as, or a portion of, the camera field of view <NUM>. The term "camera field of view" refers to the extent of the observable world that is captured by the side view camera <NUM> at any given moment, i.e., the extent of the image captured by the camera. The image captured by the side view camera <NUM>, or a portion of the image captured by the camera <NUM>, may be displayed on the display screen <NUM>. The display field of view refers to the extent of the camera field of view <NUM> that is displayed on the display screen <NUM>. The display field of view <NUM> is therefore based on how much of the camera field of view is reconstructed into an image that is displayed on the display screen <NUM>. The display field of view <NUM> can be less than or equal to the camera field of view <NUM>, but cannot be more than the camera field of view <NUM>.

A lift axle position of the at least one lift axle <NUM> may be determined by the ECU <NUM>. When a vehicle turning operation, such as right turn or left turn, for the motor vehicle <NUM> is performed, a display field of view of an image displayed on the display screen <NUM> may be adjusted based on the lift axle position during the vehicle turning operation by the ECU <NUM> to provide updated visual media data. The updated visual media data may be displayed on the display screen <NUM>, so as to display the visual media data in real-time.

Adjusting the display field of view <NUM> may be performed to maintain an end corner and/or a lateral side of the motor vehicle <NUM> fully within the display field of view <NUM> during the vehicle turning operation, such that the end corner and/or the lateral side of the motor vehicle <NUM> may be automatically tracked and kept in view while the motor vehicle <NUM> is turning. This may help to avoid right-hand turn collisions or left-hand turn collisions with motorists and pedestrians or other vehicles or objects. In other words, a better field of view, such as reduction of common blind spots, may be provided during the vehicle turning operation, so as to provide a better user experience and a more complete view of operating conditions.

Reference is made again to <FIG>, which illustrates a camera field of view <NUM> and a data region <NUM> within the camera field of view <NUM> from which the display field of view <NUM> is generated. The display field of view <NUM> can be adjusted either digitally by changing the location of the data region <NUM> within the camera field of view <NUM> or physically by repositioning/reorienting the side view camera <NUM>, such as by panning the side view camera <NUM> left or right, so that the entire field of view of the side view camera <NUM> is changed.

According to some examples, adjusting the digital field of view of the side view camera <NUM> to update the captured visual media data may include adjusting, via the ECU <NUM>, a data region <NUM> of the image data captured by the camera <NUM> that corresponds to the display field of view <NUM>.

For example, adjusting the data region <NUM> of the captured visual media data may include performing a digital transformation to the data region <NUM>, such as digitally resizing 132a (e.g., enlarging or shrinking) the data region <NUM>, panning 132b such as moving the data region <NUM> left, right, up or down, and/or rotating 132c, such as turning clockwise or counterclockwise. Thereby, displaying the updated visual media data may include displaying the adjusted data region of the captured visual media data when the field of view <NUM> of the side view camera <NUM> is the digital field of view.

Alternatively, according to some examples, the display field of view <NUM> may be adjusted by adjusting the physical field of view <NUM> of the side view camera <NUM> to update the captured visual media data. This may be performed by applying, via the ECU <NUM>, to the side view camera <NUM>, at least one action of pivoting, translating and zooming the side view camera <NUM> to further capture another visual media data. In some examples, the camera field of view <NUM> of the side view camera <NUM> may be adjusted by rotating and/or translating the side view camera <NUM> around/along at least one of a vertical axis <NUM>, a lateral axis <NUM> and a longitudinal axis <NUM>, as shown in <FIG>.

For example, a lens <NUM> of the side view camera <NUM>, or the side view camera <NUM> itself, may rotate about a vertical axis in the vertical direction <NUM> or move up and down along the vertical direction <NUM>, the lens <NUM> of the side view camera <NUM> or the side view camera <NUM> itself may rotate about a lateral axis in the lateral direction <NUM> or move left and right along the lateral direction <NUM>, and/or the lens <NUM> of the side view camera <NUM>, or the side view camera <NUM> itself, may rotate about a longitudinal axis in the longitudinal direction <NUM> or move forward and backward along the longitudinal direction <NUM>. In a further specific example, adjusting the physical field of view of the side view camera <NUM> to update the captured visual media data may include adjusting at least one of an azimuth angle <NUM> as shown in <FIG> and an elevation angle <NUM> as shown in <FIG> of the side view camera <NUM> to further capture another visual media data for updating the captured visual media data.

According to some examples, in further detail, the method further may include determining a rear turning point <NUM> of the motor vehicle <NUM> based on the lift axle position by the ECU <NUM>, as shown in <FIG> and <FIG>. Accordingly, adjusting the field of view <NUM> of the side view camera <NUM> based on the lift axle position may be performed by adjusting the field of view <NUM> of the side view camera <NUM> based on the rear turning point <NUM>.

According to some examples, the rear turning point <NUM> may change in response to a change in the lift axle position. Additionally, the motor vehicle <NUM> may include the at least one fixed axle <NUM>. The at least one fixed axle <NUM> may be adjacent the at least one lift axle <NUM>. The rear turning point <NUM> may be determined further based on each fixed axle point <NUM> of the at least one fixed axle <NUM> by the ECU <NUM>. Specifically, determining the lift axle position may include determining whether the lift axle position has changed to a raised position or to a lowered position. Accordingly, determining the rear turning point <NUM> based on the lift axle position and each fixed axle point <NUM> may be performed by designating a center point between each fixed axle point <NUM> of the at least one fixed axle <NUM> as the rear turning point <NUM> in response to determining that the lift axle position may be the raised position, and designating a center point between a lift axle point <NUM> of the at least one lift axle <NUM> and each fixed axle point <NUM> of the at least one fixed axle <NUM> as the rear turning point <NUM> in response to determining that the lift axle position may change to the lowered position.

For example, referring now to <FIG>, there may be three axles located adjacent to each other, of which one may be a lift axle <NUM> and two may be fixed axles <NUM>. When the lift axle <NUM> and the two adjacent fixed axles <NUM> are all in a lowered position, the rear turning point <NUM> may be related to the fixed axle <NUM> in the middle, as shown in <FIG>. If the lift axle <NUM> is the leftmost one or the rightmost one among these three axles and when the lift axle <NUM> may change to a raised position, the rear turning point <NUM> may change from a middle location to another location between the two fixed axles <NUM>, as shown in <FIG>. On the other hand, as shown in <FIG>, if the lift axle <NUM> is between the two adjacent fixed axles <NUM> and when the lift axle <NUM> changes to a raised position, the rear turning point <NUM> may remain unchanged in the middle location.

According to some examples, the method further may include calculating a turning radius <NUM> of the motor vehicle <NUM> based on the rear turning point <NUM> by the ECU <NUM>, as shown in <FIG> and <FIG>. Accordingly, adjusting the field of view <NUM> of the side view camera <NUM> based on the rear turning point <NUM> may be performed by adjusting the field of view <NUM> of the side view camera <NUM> based on the turning radius <NUM>. According to some examples, the turning radius <NUM> may change in response to that the rear turning point <NUM> may change. In other words, the turning radius <NUM> may change depending on the lift axle position. For example, when the lift axle position causes the motor vehicle to have a larger turning radius, the field of view <NUM> of the side view camera <NUM> and/or the field of view <NUM> of the display screen <NUM> may be adjusted by digitally or mechanically panning the field of view outwards to maintain an end of the vehicle within the field of view <NUM> of the display screen <NUM> during the turning operation. Conversely, when the lift axle position causes the motor vehicle to have a smaller turning radius, the field of view <NUM> of the side view camera <NUM> and/or the field of view <NUM> of the display screen <NUM> may be adjusted by digitally or mechanically panning the field of view inwards to maintain an end of the vehicle within the field of view <NUM> of the display screen <NUM> during the turning operation.

Referring now to <FIG> and <FIG>, the motor vehicle <NUM> may include the front axle <NUM>, and the method further may include calculating a distance between a front axle point <NUM> of the front axle <NUM> and the rear turning point <NUM> by the ECU <NUM>. Specifically, calculating the turning radius <NUM> based on the rear turning point <NUM> may be performed by calculating the turning radius <NUM> based on the distance, so as to improve the adjustment of the field of view <NUM> of the side view camera <NUM>.

Referring now to <FIG>, in an example, the motor vehicle <NUM> may include an intermediate axle <NUM> and a hitch <NUM>. The intermediate axle <NUM> may be located between the front axle <NUM> and the at least one lift axle <NUM>. The hitch <NUM> may be located between the front axle <NUM> and the at least one lift axle <NUM>, and the hitch <NUM> may be located adjacent to the intermediate axle <NUM>. Therefore, a front distance and a rear distance may be combined as the distance by the ECU <NUM>, in which the front distance between an intermediate axle point <NUM> of the intermediate axle <NUM> and the front axle point <NUM> may be calculated by the ECU <NUM> while the rear distance between a hitching point <NUM> of the hitch <NUM> and the rear turning point <NUM> may be calculated by the ECU <NUM>.

Furthermore, the motor vehicle <NUM> may include a towing vehicular part <NUM> and a towed vehicular part <NUM>, the towed vehicular part <NUM> may be attached to the towing vehicular part <NUM> via the hitch <NUM>, the front axle <NUM> may be mounted on the towing vehicular part <NUM>, the intermediate axle <NUM> may be mounted on the towing vehicular part <NUM>. The at least one lift axle <NUM> may be mounted on the towed vehicular part <NUM>. Moreover, the method further may include calculating a relative angle <NUM> between the towing vehicular part <NUM> and the towed vehicular part <NUM>, as shown in <FIG>. Calculating the turning radius <NUM> based on the rear turning point <NUM> may be performed by calculating the turning radius <NUM> based on the distance and the relative angle <NUM>, so as to improve the adjustment of the field of view <NUM> of the side view camera <NUM>.

Referring now to <FIG>, in another example, the motor vehicle <NUM> may include an intermediate axle <NUM> and a plurality of hitches <NUM>. The intermediate axle <NUM> may be located between the front axle <NUM> and the at least one lift axle <NUM>. The plurality of hitches <NUM> may be located between the front axle <NUM> and the at least one lift axle <NUM>, and the rear hitch <NUM> may be located adjacent to the at least one lift axle <NUM>. A front distance, at least one intermediate distance, and a rear distance may be combined as the distance by the ECU <NUM>. The front distance between an intermediate axle point <NUM> of the intermediate axle <NUM> and the front axle point <NUM> may be calculated by the ECU <NUM>. Each intermediate distance between two adjacent hitching points <NUM> among a plurality of hitching points <NUM> of two adjacent hitches <NUM> among the plurality of hitches <NUM> for the plurality of hitching points <NUM> may be calculated by the ECU <NUM>. The rear distance between a rear hitching point <NUM> among the plurality of hitching points <NUM> of a rear hitch <NUM> among the plurality of hitches <NUM> and the rear turning point <NUM> may be calculated by the ECU <NUM>.

The motor vehicle <NUM> may include a towing vehicular part <NUM> and a plurality of towed vehicular parts <NUM>. A front hitch <NUM> among the plurality of hitches <NUM> may be located adjacent to the intermediate axle <NUM>. A front towed vehicular part <NUM> among the plurality of towed vehicular parts <NUM> may be attached to the towing vehicular part <NUM> via the front hitch <NUM>. Two adjacent towed vehicular part <NUM> among the plurality of towed vehicular parts <NUM> may be attached to each other via each corresponding hitches <NUM> among the plurality of hitches <NUM>.

The front axle <NUM> may be mounted on the towing vehicular part <NUM>, the intermediate axle <NUM> may be mounted on the towing vehicular part <NUM>, and the at least one lift axle <NUM> may be mounted on a rear towed vehicular part <NUM> among the plurality of towed vehicular parts <NUM>. Moreover, the method further may include calculating each relative angle <NUM> between the towing vehicular part <NUM> and the front towed vehicular part <NUM> among the plurality of towed vehicular parts <NUM> and between two adjacent towed vehicular part <NUM> among the plurality of towed vehicular parts <NUM>. Calculating the turning radius <NUM> based on the rear turning point <NUM> may be performed by calculating the turning radius <NUM> based on the distance and the plurality of relative angles <NUM>.

As previously mentioned, determining the lift axle position may include determining whether the lift axle position has or will change to a raised position or to a lowered position. According to some examples, the display system <NUM> may include the lift axle position sensing device <NUM> and the data storage device <NUM> each electrically coupled with the ECU <NUM>, as shown in <FIG>. The lift axle position sensing device <NUM> may be located adjacent to the at least one lift axle <NUM>. Thus, determining whether the lift axle position changes to the raised position or to the lowered position may be performed by acquiring lift axle position data of the at least one lift axle <NUM> by the lift axle position sensing device <NUM>.

In some examples, determining whether the lift axle position changes comprises retrieving preset raised position data associated with the raised position and preset lowered position data associated with the lowered position from the data storage device <NUM>, and comparing the lift axle position data with the preset raised position data and the preset lowered position data. The lift axle position is determined to have changed to the raised position when the lift axle position data matches with the preset raised position data, and the lift axle position is determined to have changed to the lowered position when the lift axle position data may match with the preset lowered position data.

According to some examples, the motor vehicle <NUM> may include the at least one wheel <NUM> connected with the at least one lift axle <NUM>, as shown in <FIG> and <FIG>. Thus, determining whether the lift axle position changes to the raised position or to the lowered position may be performed by determining whether a wheel position of the at least one wheel <NUM> changes to an up position or to a down position by the ECU <NUM>.

In some examples, the lift axle position may be determined to change to the raised position in response to determining that the wheel position has changed to the up position. The lift axle position may be determined to have changed to the lowered position in response to determining that the wheel position has changed to the down position.

The display system <NUM> may include the wheel position/rotation sensing device <NUM> electrically coupled with the ECU <NUM>, as shown in <FIG>. The wheel position/rotation sensing device <NUM> may be located adjacent to the at least one wheel <NUM>. Thus, determining whether the wheel position has change to the up position or to the down position may be performed by acquiring wheel position data of the at least one wheel <NUM> by the wheel position/rotation sensing device <NUM>, retrieving preset up position data associated with the up position and preset down position data associated with the down position from the data storage device <NUM>, and comparing the wheel position data with the preset up position data and the preset down position data by the ECU <NUM>. The wheel position is determined to have changed to the up position in response to determining that the wheel position data matches the preset up position data. The wheel position is determined to have changed to the down position in response to determining that the wheel position data matches the preset down position data.

Alternatively, determining whether the wheel position has changed to the up position or to the down position may be performed by performing a vehicle moving operation for the motor vehicle <NUM>, acquiring a wheel rotation parameter of the at least one wheel <NUM> during the vehicle moving operation by the wheel position/rotation sensing device <NUM>, retrieving a preset rotation threshold from the data storage device <NUM>, and comparing the wheel rotation parameter with the preset rotation threshold by the ECU <NUM>. The wheel position is determined to change to the up position in response to determining that the wheel rotation parameter is smaller than the preset rotation threshold. The wheel position is determined to change to the down position in response to determining that the wheel rotation parameter is larger than the preset rotation threshold.

According to some examples, determining whether the lift axle position has change to the raised position or to the lowered position may be performed, without determining the wheel position first, by performing a vehicle moving operation for the motor vehicle <NUM>, acquiring a wheel rotation parameter of the at least one wheel <NUM> during the vehicle moving operation by the wheel position/rotation sensing device <NUM>, retrieving a preset rotation threshold from the data storage device <NUM>, and comparing the wheel rotation parameter with the preset rotation threshold by the ECU <NUM>. The wheel position is determined to change to the raised position in response to determining that the wheel rotation parameter is smaller than the preset rotation threshold, and the wheel position is determined to change to the lowered position in response to determining that the wheel rotation parameter is larger than the preset rotation threshold.

According to some examples, the visual media data may include a video data. In some examples, the visual media data may include at least one image data, and the video data may be formed by a plurality of image data captured along a timeline. For example, the data region <NUM> of the captured visual media data in real-time may be formed by a combination of a data region of a plurality of image data along a timeline.
