DETAILED DESCRIPTION

Throughout the specification and claims, unless explicitly described to the contrary, the word “comprise”, and variations such as “comprises” or “comprising”, will be understood to imply the inclusion of stated elements but not the exclusion of any other elements. Terms including an ordinary number, such as first and second, are used for describing various components, but the components are not limited by the terms. The terms are used only to discriminate one component from another component.

Terms such as “part,” “unit,” “module,” and the like in the specification may refer to a unit capable of performing at least one function or operation described herein, which may be implemented in hardware or circuitry, software, or a combination of hardware or circuitry and software. In addition, at least some of the configurations or functions of a vehicle door control method and apparatus according to the example embodiments described below may be implemented as programs or software, and the programs or software may be stored on a computer-readable medium.

FIG. 1 is a block diagram for illustrating a vehicle door control apparatus according to an example embodiment.

Referring to FIG. 1, a vehicle door control apparatus 10 according to an example embodiment may execute program codes loaded into one or more memory devices via one or more processors. For example, the vehicle door control apparatus 10 may be implemented as a computing device 50, such as that described later with reference to FIG. 9. In this case, the one or more processors may correspond to a processor 510 of the computing device 50, and the one or more memory devices may correspond to a memory 530 of the computing device 50. The program code may be executed by one or more processors to control a door based on a behavior of a user possessing a digital key in a chassis cab platform-based vehicle mounted with a cargo compartment (e.g., a tower for loading cargo) for loading cargo. The term “module” is used herein to logically distinguish between these functions executed by the program code. In some example embodiments, the vehicle door control apparatus 10 may be implemented in a chassis-cab platform-based vehicle formed of a chassis and a passenger cabin.

The vehicle door control apparatus 10 according to the example embodiment may execute program code including a short range communication module 110, a distance detection module 120, a cargo compartment mounting determining module 130, a door control module 140, a door state monitoring module 150, and a driver notification module 160. As used in the present specification, the term “driver” is not intended to be limited to the person directly operating the vehicle. Therefore, when the term “driver” is used, the scope of the term is intended to include any user who possesses a digital key and wishes to control the doors of the vehicle. In this specification, the term “driver” may be used interchangeably with the term “user.”

The short range communication module 110 may establish communication between a short range communication terminal provided in the vehicle and a mobile device 20 used by the user (for example, a driver) of the vehicle as a digital key, and may handle the process of communication between the short range communication terminal and the mobile device 20. In some example embodiments, the short range communication terminal may include a Bluetooth® beacon.

When the short range communication terminal is implemented as a Bluetooth beacon, the beacon may be a wireless transmission device that periodically transmits specific information based on Bluetooth Low Energy (BLE) technology. A signal transmitted by the beacon may be received by the mobile device 20 capable of detecting the corresponding signal, and the corresponding signal may include unique identification information of the beacon, and the mobile device 20 may identify the beacon based on the unique identification information.

Here, the digital key may provide a function to control the vehicle or implement interaction with the vehicle by using the mobile device 20. For example, a user may be able to lock or unlock the doors of the vehicle, remotely start the engine of the vehicle, or remotely control the air conditioner, horn, lights, and the like by using the possessed digital key via the mobile device 20. Further, as users specify user profiles, vehicle settings customized for each user, such as seat positioning, mirror positioning, and cabin temperature settings. may be automatically applied.

In some example embodiments, the mobile device 20 may include a smartphone, tablet computer, wearable device, laptop computer, or the like, but is not limited to those listed.

The distance detection module 120 may detect a change in distance between the digital key and the vehicle via communication of the mobile device 20 with the short range communication terminal performed by the short range communication module 110. For example, the distance detection module 120 may detect, via communication between the short range communication terminal and the mobile device 20, whether the digital key is away from the vehicle by a predetermined distance or more. Alternatively, the distance detection module 120 may detect, via the communication between the short range communication terminal and the mobile device 20, whether the digital key is closer to the vehicle by a predetermined distance or less.

In some example embodiments, the distance detection module 120 may estimate a distance between the digital key and the short range communication terminal by using a Received Signal Strength Indicator (RSSI) value, and may detect when the estimated distance is equal to or more than a predetermined distance, or may detect when the estimated distance is equal to or less than a predetermined distance. RSSI is an indicator of signal strength measured when receiving a wireless signal, and when a short range communication terminal periodically transmits a signal, the mobile device 20 may measure the strength of the corresponding signal, thereby estimating the distance between the mobile device 20 and the short range communication terminal. AS needed, implementations, such as increasing the number of times of the measurement or using average values, may be used to compensate for signal interference, such as obstacles, or multipath effects where the signal may be distorted by the signal reaching the mobile device 20 via multiple paths.

When it is detected that the digital key is away from the vehicle by the predetermined distance or more, or when it is detected that the digital key is closer to the vehicle by the predetermined distance or less, the distance detection module 120 may set a flag value to represent the case.

The cargo compartment mounting determining module 130 may determine whether the cargo compartment (e.g., a cargo compartment for loading cargo) is mounted at the rear of the cab, that is, at the rear of the passenger cabin. Since the chassis cab platform-based vehicle may be operated without being mounted with a cargo compartment, it is necessary to recognize whether the rear of the cab is mounted with the cargo compartment in order to control the door of the cargo compartment, as described in the following example embodiments.

In some example embodiments, the cargo compartment mounting determining module 130 may determine that the cargo compartment is mounted at the rear of the cab when a voltage value on a connector pin provided on the cargo compartment falls within a first range. For example, the cargo compartment mounting determining module 130 may determine that the cargo compartment is not mounted at the rear of the cab when the voltage value of a connector pin provided on the cargo compartment is measured to be a value in a range of 8 V or more. On the other hand, the cargo compartment mounting determining module 130 may determine that the cargo compartment is not mounted at the rear of the cab when the voltage value of the connector pin provided on the cargo compartment falls within a second range that is different from the first range. For example, the cargo compartment mounting determining module 130 may determine that the cargo compartment is mounted at the rear of the cab when the voltage value of the connector pin provided on the cargo compartment is measured to be a value in a range of 0.5 V or less.

The door control module 140 may control the door installed in the cargo compartment in consideration of at least one of a condition regarding the state of the vehicle, a condition regarding the state of the door, a condition regarding whether a flag value is set, and various other conditions. For example, the door control module 140 may close the door when it is determined that the vehicle is stopped, the door is in the open state, and it is detected that the digital key is away from the vehicle by the predetermined distance or more and the flag value is set. As another example, the door control module 140 may unlock the door when it is determined that the vehicle is stopped, the door is in the locked state, and it is detected that the digital key is closer to the vehicle by the predetermined distance or less and the flag value is set. As another example, the door control module 140 may open the door when it is determined that the vehicle is stopped, the door is in the closed state, and it is detected that the digital key is closer to the vehicle by the predetermined distance or less and the flag value is set. In another example, the door control module 140 may open the door of the vehicle when the vehicle is stopped, the driver's seat belt is not fastened, the driver is not seated in the driver's seat, a driver's seat door open event has occurred, a stop event has occurred, it is detected that the digital key is closer by the predetermined distance or less from the vehicle and the first flag value is set, and the vehicle has arrived at a destination and a second flag value is set.

The door state monitoring module 150 may monitor whether the door is controlled as requested by the door control module 140. For example, the door state monitoring module 150 may monitor the open and close state or locked state of the door after the door control module 140 transmits a request to close the door, a request to lock the door, a request to unlock the door, or a request to open the door, and may determine that the door is successfully closed, successfully locked, successfully unlocked, or successfully opened when the monitoring results indicate that the door has changed to the closed state, the locked state, the unlocked state, or the open state within a predetermined time period. Alternatively, when the monitoring results indicate that the door has not changed to the closed state, locked state, unlocked state, or open state within the predetermined time period, the door state monitoring module 150 may determine that the door is not successfully closed, not successfully locked, not successfully unlocked, or not successfully opened.

The driver notification module 160 may notify the driver, via the mobile device 20, of the results monitored by the door state monitoring module 150. For example, the driver notification module 160 may notify the driver, via the mobile device 20, whether the door was successfully closed, whether the door was successfully locked, whether the door was successfully unlocked, or whether the door was successfully opened.

In some example embodiments, the driver notification module 160 may notify the mobile device 20 of the monitoring results via the short range communication terminal. For example, the driver notification module 160 may notify the mobile device 20, via the short range communication terminal, whether the door was successfully closed, whether the door was successfully locked, whether the door was successfully unlocked, or whether the door was successfully opened.

FIG. 2 is a flow diagram for illustrating a vehicle door control method according to an example embodiment.

For example, operation S202 may perform detecting whether the digital key is away from the vehicle by 4.5 m or more, or detecting whether the digital key is away from the vehicle to a range of 4.5 m±0.5 m. In some example embodiments, the driver may set a distance value or a range value, via the User Setting Mode (USM), for the case where the digital key is away from the vehicle by a certain distance or more and is detected, or when the digital key is away from the vehicle to a certain range and is detected.

On the other hand, in some example embodiments, operation S207 may include notifying the mobile device 20, via the short range communication terminal, whether the door was successfully closed.

According to the example embodiment, it is possible to provide automated door control in which a door (e.g., a power sliding door) installed in the cargo compartment is automatically closed when a user with a digital key walks away from the vehicle, thereby meeting the user's needs without directly closing a door by the user.

In some example embodiments, operation S604 may be implemented by a method of determining whether the vehicle has arrived at the destination based on destination information set by the driver or delivery schedule information provided from an external server, for example, based on current global positioning system (GPS) location information of the vehicle. If the vehicle is determined to have arrived at the destination S604, ‘Y’, the vehicle door control method may perform setting a second flag value S605, and when not S604, ‘N’, the vehicle door control method may perform operation S604 again.

In the meantime, the vehicle door control method may perform determining whether the cargo compartment is mounted at the rear of the cab S606. In some example embodiments, operation S606 may be implemented by the method of determining whether the cargo compartment is mounted based on a voltage value of the connector pin provided on the cargo compartment, as previously described with reference to FIG. 1. When it is determined that the cargo compartment is mounted at the rear of the cab S606, ‘Y’, the vehicle door control method may perform determining whether the vehicle is stopped, the driver's seat belt is not fastened, the driver is not seated in the driver's seat, the driver's seat door opening event has occurred, the stop event has occurred, and the first flag value and the second flag value have been set S607, and when not S606, ‘N’, the vehicle door control method may perform operation S606 again.

Subsequently, the vehicle door control method may perform opening the door when it is determined that the vehicle is stopped, the driver's seat belt is not fastened, the driver is not seated in the driver's seat, the driver's seat door open event has occurred, the stop event has occurred, and the first flag value and the second flag value are set S608, and notifying the driver, via the mobile device 20, whether the door was successfully opened S609. Here, the driver's seat door open event may be an event that occurs when the driver's seat door changes from the closed state to the open state after the vehicle is stopped, and the stop event may be an event that occurs when the vehicle is stopped after the vehicle speed is a predetermined speed (e.g., 20 k/h) or more.

In some example embodiments, operation S609 may include monitoring the opening and closing state of the door after transmitting a request to open the door, determining that the door is successfully opened when the monitoring results indicate that the door has changed to the open state within a predetermined first time period (e.g., 10 seconds), and determining that the door is not successfully opened when the monitoring results indicate that the door has not changed to the open state within the first time period (e.g., 10 seconds). On the other hand, in the meantime, in some example embodiments, operation S609 may include notifying the mobile device 20, via the short range communication terminal, whether the door was successfully opened.

According to the example embodiment, it is possible to provide automated door control in which a door (e.g., a power sliding door) installed in the cargo compartment is automatically opened when a vehicle of a user with a digital key arrives at a destination and the door of the driver's seat is open, thereby meeting the user's needs without the need for the user to directly open the door.
