The controller120may apply torque in a direction opposite to a direction where the door is opened, may increase or decrease torque in the direction opposite to the direction where the door is opened, and may control such that the door is opened to a specific degree.

FIG.2is a block diagram illustrating a detailed configuration of a passenger safe exit assist device according to an embodiment of the present disclosure.

A sensor device210may include a vehicle side state and distance measuring device211, a driver body type measuring device212, a door opening speed measuring device213, a door opening acceleration measuring device214, and a door opening weight measuring device215.

The vehicle side state and distance measuring device211may recognize an obstacle around the vehicle in a side direction and may measure a distance between a door of the vehicle and the obstacle.

As an example, the vehicle side state and distance measuring device211may include at least one of a radar or a camera.

The driver body type measuring device212may measure at least one of a front body type and a side body type of a driver by means of the camera.

As an example, the driver body type measuring device212may include at least one of a driver front camera or a driver side camera provided in the vehicle.

The door opening negative torque load device230may apply a negative torque in a direction opposite to a direction where the door of the vehicle is opened.

As an example, the door opening negative torque load device230may receive a control signal from the controller220and may apply the negative torque in the direction opposite to the direction where the door of the vehicle is opened.

The alert device240may include at least one of a warning symbol display device241or a warning sound generator242.

The warning symbol display device241may receive an alert control signal from the controller220and may display or turn on/off a warning symbol by means of at least one of a cluster or an audio, video, navigation (AVN) of the vehicle.

The warning sound generator242may receive an alert control signal from the controller220and may output a warning sound by means of at least one of a horn, an audio, or an AVN of the vehicle.

The input device250may include a safe exit mode input device251and an automatic door opening input device252.

The safe exit mode input device251may receive a safe exit mode of the vehicle from a user.

As an example, the safe exit mode input device251may receive a safe exit mode from the user, through a mode selection button and a user selecting mode (USM).

As an example, the safe exit mode input device251may receive the safe exit mode from the user, through the number of times the mode selection button is pushed or a time when the mode selection button is pushed.

In detail, when the mode selection button of the safe exit mode input device251is pushed once, the controller220may determine that a mode where a degree to which the door is opened is set according to a reference body type is input. When the mode selection button is pushed two times, the controller220may determine that a mode where a degree to which the door is opened is set according to a front body type of a driver is input. When the mode selection button is pushed three times, the controller220may determine that a mode where a degree to which the door is opened is set according to a side body type of the driver is input.

As an example, when the safe exit mode input device251receives an owner mode, the controller220may set a degree to which the door is opened according to the front body type of the driver and a degree to which the door is opened according to the side body type of the driver, using body type information stored in a memory.

To this end, the controller220may store body type information according to the user in the memory in advance.

When the owner mode is selected, the controller220may immediately use a previously stored value without measuring a body type by means of a camera. When the owner mode is not selected, the controller220may use a degree to which the door is opened, which is set with regard to a body type of the driver.

The automatic door opening input device252may receive a signal for automatically opening the door of the vehicle from the user.

As an example, the automatic door opening input device252may include at least one of an auto door open switch or an auto door open handle.

As an example, the automatic door opening input device252may detect manipulation of at least one of the auto door open switch or the auto door open handle and may receive a signal for automatically opening the door from the user.

FIG.3is a flowchart illustrating a process of controlling a speed of a door in a manual mode in a passenger safe exit assist device according to an embodiment of the present disclosure.

Referring toFIG.3, in S301, a passenger safe exit assist device100ofFIG.1may determine that a driver selects a safe exit mode.

As an example, a controller220ofFIG.2may identify a safe exit mode selected by the driver among a among a number of modes. One mode may be where a degree to which the door is opened is set according to a reference body type. Another mode may be where a degree to which the door is opened is set according to a front body type of the driver. Another mode may be where a degree to which the door is opened is set according to a side body type of the driver, by means of a safe exit mode input device251ofFIG.2.

After determining that the driver selects the safe exist mode, in S302, the passenger safe exit assist device100may generate a third line.

As an example, the controller220may set the third line based on a degree to which the door is opened, corresponding to a mode selected from among a number of modes. In one example, these modes may include the mode where the degree to which the door is opened is set according to the reference body type, the mode where the degree to which the door is opened is set according to the front body type of the driver, and the mode where the degree to which the door is opened is set according to the side body type of the driver.

As an example, when the mode where the degree to which the door is opened is set according to the reference body type or the front body type of the driver is selected, the controller220may set the third line based on a degree to which the door is opened, which is calculated such that an area where the reference body type or the front body type is reflected may pass, and a degree to which the door is additionally opened, which is set to prevent a contact with an obstacle when the door is opened.

As an example, when the mode where the degree to which the door is opened is set according to the side body type of the driver is selected, the controller220may set the third line based on only a degree to which the door is opened according to the side body type of the driver without regard to a distance between the vehicle and the obstacle.

After generating the third line, in S303, the passenger safe exit assist device100may identify a parking space and may generate a first line.

As an example, the controller220may identify the parking space by means of an image around the vehicle, which is obtained by means of a camera.

As an example, the controller220may generate a virtual first line along an obstacle around the parking space.

After identifying the parking space and generating the first line, in S304, the passenger safe exit assist device100may determine whether it is possible to park.

As an example, the controller220may determine whether it is possible to park, based on whether an expected parking path of the vehicle and the first line are overlapped with each other.

When it is determined that it is impossible to park, in S305, the passenger safe exit assist device100may turn on/off a warning symbol and may sound a warning sound.

As an example, the controller220may deliver an alert signal to an alert device240ofFIG.2to display or turn on/off a warning symbol by means of at least one of a cluster or an AVN and to output a warning sound by means of at least one of a horn, an audio, or an AVN of the vehicle.

After turning on/off the warning symbol and sounding the warning sound, the passenger safe exit assist device100may perform S303again.

When it is determined that it is possible to park, in S306, the passenger safe exit assist device100may determine whether the distance between the vehicle and the first line is less than 90% of a distance between the vehicle and a second line set based on a degree to which the door of the vehicle is maximally opened.

As an example, the controller220may set the second line based on the degree to which the door of the vehicle is maximally opened and may determine whether the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line is greater than a first reference ratio.

Herein, the numerical value 90% may be a value set randomly to give an example of the first reference ratio and may be actually set to another ratio.

When it is determined that the distance between the vehicle and the first line is not less than 90% of the distance between the vehicle and the second line set based on the degree to which the door of the vehicle is maximally opened, in S307, the passenger safe exit assist device100may control such that the door is opened by reflecting the will of a passenger (i.e., opened by a passenger without torque applied by the passenger safe exit device).

As an example, because a space where it is able to open the door is sufficient, the controller220may fail to provide torque to the door, such that the door is opened according to the will of the passenger.

When it is determined that the distance between the vehicle and the first line is less than 90% of the distance between the vehicle and the second line, in S308, the passenger safe exit assist device100may detect a weight applied to the door.

As an example, the controller220may detect a weight applied to the door, by means of a door opening weight measuring device215ofFIG.2.

After detecting the weight applied to the door, in S309, the passenger safe exit assist device100may determine whether the speed at which the door is opened is greater than a reference speed.

As an example, the controller220may obtain the speed at which the door is opened by means of a door opening speed measuring device213ofFIG.2and may compare the obtained speed with a reference speed stored in a memory to determine whether the speed at which the door is opened is greater than the reference speed.

When it is determined that the speed at which the door is opened is not greater than the reference speed, in S312, the passenger safe exit assist device100may control such that the door is opened to the first line.

As an example, when it is determined that there is no damage to a surrounding obstacle and the vehicle as the passenger slowly opens the door, the controller220may control such that the door is opened to the first line without applying torque to the door.

When it is determined that the speed at which the door is opened is greater than the reference speed, in S310, the passenger safe exit assist device100may apply negative torque of a direction where the door is opened.

As an example, when the speed at which the door is opened is greater than the reference speed, the controller220may apply torque in a direction opposite to a direction where the door is opened to control a speed at which the door is opened.

As an example, when the speed at which the door is opened is greater than the reference speed, the controller220may deliver a control signal to a door opening negative torque load device230ofFIG.2and may assign torque in a direction opposite to the direction where the door is opened.

After assigning the negative torque of the direction where the door is opened, in S311, the passenger safe exit assist device100may control such that the door is opened at a low speed.

As an example, the controller220may assign torque in the direction opposite to the direction where the door is opened to control such that the door is opened at a reference speed.

After controlling such that the door is opened at the low speed, in S312, the passenger safe exit assist device100may control such that the door is opened to the first line.

FIG.4is a flowchart illustrating a process of controlling a speed of a door depending on acceleration of the door in a manual mode in a passenger safe exit assist device according to an embodiment of the present disclosure.

Referring toFIG.4, in S401, a passenger safe exit assist device100ofFIG.1may determine whether acceleration at which the door is opened is greater than reference acceleration.

As an example, a controller220ofFIG.2may obtain acceleration at which the door is opened by means of a door opening acceleration measuring device214ofFIG.2and may compare the obtained acceleration with reference acceleration stored in a memory to determine whether the acceleration at which the door is opened is greater than the reference acceleration.

When it is determined that the acceleration at which the door is opened is not greater than the reference acceleration, in S405, the passenger safe exit assist device100may control such that the door is opened to a first line.

As an example, when the acceleration at which the door is opened is not greater than the reference acceleration, the controller220may control such that the door is opened to the first line, without increasing torque applied to the door.

When it is determined that the acceleration at which the door is opened is greater than the reference acceleration, in S402, the passenger safe exit assist device100may increase a negative torque depending on a degree to which the door is opened.

As an example, the controller220may deliver a control signal to a door opening negative torque load device230ofFIG.2to increase a negative torque depending on a degree to which the door is opened.

After increasing the negative torque depending on the degree to which the door is opened, in S403, the passenger safe exit assist device100may determine whether the acceleration at which the door is opened is not greater than the reference acceleration.

As an example, the controller220may obtain the acceleration at which the door is opened by means of the door opening acceleration measuring device214and may compare the obtained acceleration with the reference acceleration stored in the memory to determine whether the acceleration at which the door is opened is greater than the reference acceleration, in the same manner as that in S401.

When it is determined that the acceleration at which the door is opened is greater than the reference acceleration, the passenger safe exit assist device100may perform S402again.

When it is determined that the acceleration at which the door is opened is not greater than the reference acceleration, in S404, the passenger safe exit assist device100may fix the negative torque.

After fixing the negative torque, in S405, the passenger safe exit assist device100may control such that the door is opened to the first line.

Referring toFIG.5, in S501, a passenger safe exit assist device100ofFIG.1may determine that a driver selects a safe exit mode.

After determining that the driver selects the safe exist mode, in S502, the passenger safe exit assist device100may generate a third line.

After generating the third line, in S503, the passenger safe exit assist device100may identify a parking space and may generate a first line.

After identifying the parking space and generating the first line, in S504, the passenger safe exit assist device100may determine whether it is possible to park.

When it is determined that it is impossible to park, in S505, the passenger safe exit assist device100may turn on/off a warning symbol and may sound a warning sound.

After turning on/off the warning symbol and sounding the warning sound, the passenger safe exit assist device100may perform S503again.

Because S501to S505are the same as S301to S305ofFIG.3, a detailed description thereof is omitted.

When it is determined that it is possible to park, in S506, the passenger safe exit assist device100may determine whether the distance between the vehicle and the first line is less than 90% of a distance between the vehicle and a second line set based on a degree to which the door of the vehicle is maximally opened.

As an example, a controller220ofFIG.2may determine whether the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line set based on the degree to which the door is maximally opened is greater than a second reference ratio.

Herein, the numerical value 90% may be a value set randomly to give an example of the second reference ratio and may be actually set to the same value as the first reference ratio or may be set to a value different from the first reference ratio.

When it is determined that the distance between the vehicle and the first line is not less than 90% of the distance between the vehicle and the second line, in S507, the passenger safe exit assist device100may determine that the door open switch or the auto open handle of the driver's seat is manipulated.

As an example, the controller220may determine that the door open switch or the auto open handle of the driver's seat is manipulated, by means of an automatic door opening input device252ofFIG.2.

As an example, the controller220may automatically open the door of the driver's seat to the first line, depending on a signal for automatically opening the door of the driver's seat.

As an example, when it is determined that the distance between the vehicle and the first line is not less than 90% of the distance between the vehicle and the second line and when it is determined that the door open switch or the auto open handle of the driver's seat is manipulated, the passenger safe exit assist device100may control such that the door of the driver's seat is opened at a specific speed previously stored in a memory.

As an example, the controller220may control such that the door of the driver's seat is opened to the first line at a predetermined speed, depending on the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line.

As an example, when the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line is less than or equal to 60% compared to being less than or equal to 80%, the controller220may control such that the door of the driver's seat is opened to the first line at a lower predetermined speed.

After controlling such that the door is opened slowly to the first line, in S511, the passenger safe exit assist device100may determine whether an additional weight is detected in the direction where the door is opened.

As an example, the controller220may determine whether the additional weight is detected in the direction where the door is opened, by means of a door opening weight measuring device215ofFIG.2.

When it is determined that the additional weight is detected in the direction where the door is opened, in S512, the passenger safe exit assist device100may apply a negative torque of the direction where the door is opened, such that a phenomenon in which the door is suddenly opened does not occur.

As an example, the controller220may deliver a control signal to a door opening negative torque load device230ofFIG.2and may assign torque in a direction opposite to the direction where the door of the driver's seat is opened, such that the phenomenon in which the door is suddenly opened does not occur.

FIG.7is a flowchart illustrating a passenger safe exit assist method according to an embodiment of the present disclosure.

Referring toFIG.7, the passenger safe exit assist method may include obtaining (S710) information of an obstacle around a vehicle and a speed at which a door of the vehicle is opened, setting (S720) a virtual first line along the obstacle, and controlling (S730) the speed at which the door is opened, based on at least one of the first line or the speed.

The obtaining (S710) of the information of the obstacle around the vehicle and the speed at which the door of the vehicle is opened may be performed by means of a vehicle side state and distance measuring device211and a door opening speed measuring device213of a sensor device210ofFIG.2.

The setting (S720) of the virtual first line along the obstacle may be performed in a process of assisting parking or may be performed by a controller220ofFIG.2using an image obtained by means of the sensor device210through a separate process.

The controlling (S730) of the speed at which the door is opened based on the at least one of the first line or the speed may be performed by means of the controller220and a door opening negative torque load device230ofFIG.2.

As an example, the controlling (S730) of the speed at which the door is opened based on the at least one of the first line or the speed may include determining whether to control the speed at which the door is opened, depending on whether the ratio of a distance between the vehicle and the first line to a distance between the vehicle and a second line set based on a degree to which the door of the vehicle is maximally opened.

As an example, the controlling (S730) of the speed at which the door is opened based on the at least one of the first line or the speed may include applying torque in a direction opposite to a direction where the door is opened to control the speed at which the door is opened, when the speed is greater than a reference speed, and increasing torque in the direction opposite to the direction where the door is opened depending to a degree to which the door is opened, when acceleration is greater than reference acceleration.

As an example, the controlling (S730) of the speed at which the door is opened based on the at least one of the first line or the speed may include opening the door of the driver's seat at a specific speed, when the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line set based on the degree to which the door of the vehicle is maximally opened is greater than a second reference ratio, depending on a signal for automatically opening the door of the driver's seat. The controlling (S370) of the speed at which the door is opened may also include opening the door of the driver's seat at a predetermined speed depending on the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line, when the ratio of the distance between the vehicle and the first line to the distance between the vehicle and the second line is not greater than the second reference ratio, depending on the signal for automatically opening the door of the driver's seat. The controlling (S370) of the speed at which the door is opened may also include applying torque in the direction opposite to the direction where the door of the driver's seat is opened, when a force is applied in the direction where the door of the driver's seat is opened, in a state where the door of the driver's seat is opened to the first line.

As an example, the controlling (S730) of the speed at which the door is opened based on the at least one of the first line or the speed may include automatically opening a different door rather than the door of the driver's seat to a third line, depending on a signal for automatically opening the different door rather than the door of the driver's seat. The controlling (S370) of the speed at which the door is opened may also include applying torque in a direction opposite to a direction where the different door rather than the door of the driver's seat is opened to open the different door rather than the door of the driver's seat to the first line, when a force is applied in the direction where the different door rather than the door of the driver's seat is opened, in a state where the different door rather than the door of the driver's seat is opened to the third line.
