Description

Technical Field

[0001] The present invention relates to the field of intelligent vehicle body control technology, and in particular to an intelligent vehicle body control method, device, system and storage medium based on a camping mode. Background Art

[0002] With the continuous development of society and the gradual expansion of the automobile consumer group, the comfort and convenience of automobiles have become increasingly important. As a smart body control method, the intelligent unlocking function is widely used. When the driver gets out of the car with the key and closes the four doors, the vehicle will automatically locate the key position and automatically lock the car after determining that the key has left. The advantage of this function is that it realizes a non-sensitive smart car experience, eliminating the trouble of the driver taking out the key from the bag to manually lock the car, greatly improving the user experience.

[0003] To meet the outdoor activity needs of young users of smart cars, most smart cars now have outdoor camping modes. Due to the particularity of outdoor camping activities, vehicles are not only a means of transportation, but also a multifunctional center integrating entertainment, logistics, and rest, which is the core of outdoor camping. Therefore, realizing intelligent body control in outdoor camping scenarios has put forward new requirements for intelligent unlocking functions.

[0004] However, the existing intelligent unlocking function still has some shortcomings when applied to specific scenarios such as outdoor camping:

[0005] When the driver (key holder) and other passengers are near the vehicle, if the four doors of the vehicle are closed, the driver frequently moves near the vehicle, which will repeatedly trigger the smart unlocking operation, affecting the user experience. Therefore, in the existing solution, the driver can only leave the key in the car or keep the door open. When the user needs to temporarily leave the vehicle, he needs to consciously look for the key before leaving the vehicle, otherwise the vehicle will not be locked and guarded, and there is a risk of theft.

[0006] At the same time, when the driver is away from the vehicle, there may still be other passengers moving around the vehicle. If the driver takes the key away, other passengers will not be able to open the door, resulting in a poor user experience. Summary of the invention

[0007] The technical problem to be solved by the present invention is that the present invention proposes an intelligent body control method, device, system and storage medium based on the camping mode, which realizes the intelligent active locking function in the outdoor camping scene by optimizing the smart key search and locking strategy, thereby improving the user experience and ensuring the safety of the vehicle.

[0008] As one aspect of the present invention, there is provided an intelligent vehicle body control method based on a camping mode, which comprises the following steps:

[0009] After receiving the command to enter the camping mode, the high-power key search mode is started to detect the real-time location of the smart remote control key;

[0010] According to the detected real-time position of the smart remote control key, a preset smart vehicle body control strategy is selected to switch the search mode, and whether the vehicle body needs to be locked and fortified; wherein the position of the smart remote control key is located in an effective area inside the vehicle, within an effective area outside the vehicle, and away from an effective area outside the vehicle;

[0011] Among them, when it is detected that the key leaves the effective area, if a door opening operation is detected within a predetermined timing period, the control will not lock the vehicle body; if no door opening operation is detected within the predetermined timing period, the control will lock the vehicle body.

[0012] The method of selecting a preset intelligent vehicle body control strategy to switch the search mode according to the detected real-time position of the intelligent remote control key and determining whether the vehicle body needs to be locked and fortified further includes:

[0013] In the high-power key search mode, if the smart remote control key is detected in the effective area inside the vehicle, it will switch to the key search prohibition mode and cancel the lock arming operation;

[0020] In the low power key search mode, if a door opening operation is detected, the timer in the low power key search mode is reset;

[0021] In the low-power key search mode, if a door lock trigger operation is detected, the vehicle lock arming operation is performed.

[0022] The vehicle locking and defense operation includes controlling the closing of the door lock motor and starting the vehicle's safety system;

[0023] During the locked and armed stage, if the alarm is triggered, the vehicle controller (VCU) will cut off the vehicle's external discharge and send out an alarm signal through the lights and horn.

[0024] Among them, after receiving the command to enter the camping mode, the high-power key search mode is started to detect the real-time location of the smart remote control key, specifically:

[0025] After receiving the command to enter the camping mode, it is monitored whether the vehicle doors are closed. When it is detected that the vehicle doors are all closed, the high power consumption key search mode is started to detect the real-time position of the smart remote control key.

[0026] As another aspect of the present invention, there is also provided an intelligent vehicle body control device based on a camping mode, comprising:

[0029] Among them, when it is detected that the key leaves the effective area, if a door opening operation is detected within a predetermined timing period, the control will not lock the vehicle body; if no door opening operation is detected within the predetermined timing period, the control will lock the vehicle body.

[0030] Wherein, the locking logic execution unit includes:

[0032] The second execution unit is used for maintaining the high-power key search mode when the camping mode start unit detects that the smart remote control key is located in the effective area outside the vehicle, and switching to the key search prohibition mode after a first time, and canceling the locking and defense operation; if the smart remote control key is detected to be changed away from the effective area outside the vehicle within the first time, switching to the low-power key search mode, and performing the vehicle locking and defense operation for a second time;

[0033] The third execution unit is used to switch to the low-power key search mode and perform the locking operation after a third time when the camping mode starting unit detects that the smart remote control key is away from the effective area outside the vehicle.

[0034] Among them, in the high-power key search mode, the key position inside and outside the car is searched at the same time, and the wireless charging module (WCM) function of the car mobile phone is turned off;

[0035] In low-power key search mode, only the key position outside the vehicle is searched, and the vehicle-mounted mobile phone wireless charging module (WCM) function is turned on;

[0036] In the key search prohibition mode, the search for the key position is stopped and the vehicle-mounted mobile phone wireless charging module (WCM) function is turned on.

[0037] Among them, in the low-power key search mode, if it is detected that the key re-enters the effective area outside the vehicle, it returns to the high-power key search mode and resets the timer in the high-power key search mode;

[0038] In the low power key search mode, if a door opening operation is detected, the timer in the low power key search mode is reset;

[0039] In the low-power key search mode, if a door lock trigger operation is detected, the vehicle lock arming operation is performed.

[0040] The vehicle locking and defense operation includes controlling the closing of the door lock motor and starting the vehicle's safety system;

[0041] During the locked and armed stage, if the alarm is triggered, the vehicle controller (VCU) will cut off the vehicle's external discharge and send out an alarm signal through the lights and horn.

[0042] Accordingly, another aspect of the present invention further provides an intelligent vehicle body control system based on a camping mode, comprising:

[0043] An integrated body control module, for managing the execution logic of the vehicle locking and arming operation when the vehicle is in camping mode, which is deployed with the intelligent body control device as described above;

It can realize non-sensitive vehicle body safety control and improve user experience.

[0053] In the present invention, through the intelligent locking control logic (when it is detected that the key has left the effective area, if someone opens the door during the timing period, the vehicle will not be locked, and other keyless users can use it normally; if no one opens the door during the timing period, it will be controlled to lock), active and passive combined locking defense in the keyless situation is realized; thereby, by optimizing the key search and locking strategy, misjudgment and repeated triggering are reduced, and the user's car experience in camping scenarios is improved. At the same time, it can ensure that the vehicle is automatically locked when the user is away for a long time and there is no one around, preventing the vehicle from being stolen and improving safety.

[0059] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0060] like Figure 1 FIG. 1 is a schematic diagram showing a structure of an embodiment of an intelligent vehicle body control system based on a camping mode provided by the present invention; in this embodiment, the intelligent vehicle body control system at least includes:

[0061] An integrated body control module (IBCM) that manages the execution logic of the vehicle arming operation when the vehicle is in camping mode, and can manage the corresponding security state and key search mode;

[0062] Intelligent hub unit (IHU), which sends a camping mode on command to the integrated body control module;

[0063] The intelligent detection antenna includes an in-vehicle antenna and an out-vehicle antenna, and is used to periodically transmit signals at a preset frequency to search for the location of the intelligent remote control key in response to the command of the integrated body control module; specifically, the intelligent detection antenna can transmit 125KHz electromagnetic waves for key search, and its transmission period can be, for example, once every 500ms, or once every 750ms;

[0064] The radio frequency receiving module (RFR) is used to analyze the position signal returned by the smart remote control key to determine the position of the smart remote control key; it can be understood that when the smart remote control key receives the 125KHz key search signal, it will immediately send a 433.92MHz electromagnetic wave signal, which will be received by the radio frequency receiving module (hereinafter referred to as RFR). After receiving the key position signal, the RFR transmits it to the IBCM through the private LIN line;

[0065] A door detection switch, used to detect the open / closed state of the door and report the open / closed state signal to the integrated body control module; specifically, the door detection switch may be, for example, a door ajar switch;

[0066] Four-door lock motors, used to perform door lock opening and closing operations according to the instructions of the integrated body control module;

[0067] The vehicle controller communicates with the integrated body control module and is used to cut off external power supply when an alarm occurs during the locking and arming phase;

[0068] The vehicle-mounted mobile phone wireless charging module (WCM) is used to wirelessly charge the vehicle-mounted mobile phone. Its charging signal may interfere with the electromagnetic wave signal sent by the smart remote control key.

[0069] In this embodiment, the specific details of the functions of the integrated body control module (IBCM) are described below in conjunction with Figure 2 Describe in detail.

[0070] like Figure 2 FIG. 1 is a schematic diagram showing a structure of an embodiment of an intelligent vehicle body control device based on a camping mode provided by the present invention; in this embodiment, the intelligent vehicle body control device 1 is deployed in Figure 1 Specifically, the intelligent vehicle body control device 1 based on the camping mode at least includes:

[0071] The camping mode start unit 10 is used to monitor whether the vehicle doors are all closed after receiving the command to enter the camping mode, and when it is detected that all four doors of the vehicle are closed, start the high power consumption key search mode to detect the real-time position of the smart remote control key; wherein the position of the smart remote control key is located in the effective area inside the vehicle, within the effective area outside the vehicle, and away from the effective area outside the vehicle;

[0072] Specifically, after the IBCM determines that the four doors of the vehicle are closed, it uses a hard-wired intelligent detection antenna to send 125KHz electromagnetic waves for key search. When the smart remote control key receives the 125KHz key search signal, it will immediately send a 433.92MHz electromagnetic wave signal, which is received by the radio frequency receiving module (RFR). After receiving the key position signal, the RFR feeds back to the IBCM through the private LIN line. After receiving it, the IBCM can know the real-time location of the smart remote control key. In this embodiment, if the IBCN cannot detect the real-time location information of the smart remote control key, it can be determined to be located in an effective area far away from the outside of the vehicle.

[0073] The locking logic execution unit 11 is used to select a preset intelligent vehicle body control strategy to switch the search mode according to the detected real-time position of the intelligent remote control key, and determine whether the vehicle body needs to be locked and fortified;

[0074] In this embodiment, when it is detected that the key leaves the effective area, if a door opening operation is detected within a predetermined timing period, the vehicle body is controlled not to be locked and fortified; if a door opening operation is not detected within the predetermined timing period, the vehicle body is controlled to be locked and fortified. More specifically, the locking logic execution unit 11 further includes:

[0075] The first execution unit 110 is used to switch to the key search prohibition mode and cancel the locking and fortification operation when the camping mode start unit detects that the smart remote control key is located in the effective area in the vehicle;

[0076] The second execution unit 111 is used to maintain the high-power key search mode when the camping mode start unit detects that the smart remote control key is located in the effective area outside the vehicle, and switch to the key search prohibition mode after a first time (such as 10 minutes), and cancel the locking and defense operation; if it is detected that the smart remote control key is changed to be away from the effective area outside the vehicle within the first time, it is switched to the low-power key search mode, and the vehicle locking and defense operation is performed for a second time (such as 30 minutes);

[0077] The third execution unit 112 is used to switch to the low-power key search mode when the camping mode start unit detects that the smart remote control key is away from the effective area outside the vehicle, and perform a locking operation after a third time (such as 10 minutes).

[0078] In a specific example, in the high-power key search mode, the key positions inside and outside the car are searched at the same time, and the in-car mobile phone wireless charging module (WCM) function is turned off; in a specific example, in the high-power key search mode, the search is performed every 500ms, and the smart detection antennas inside and outside the car start working at the same time. IBCM can know in real time whether the legal key is in the effective detection area inside and outside the car. In addition, during the key search, the WCM function needs to be actively shielded to prevent the key from being placed directly above the WCM, resulting in the key position being unable to be identified, affecting the key search function.

[0079] In low-power key search mode, only the location of the key outside the car is searched, and the in-vehicle mobile phone wireless charging module (WCM) function is turned on; in a specific example, in low-power key search mode, the search is performed every 750ms, the smart detection antenna inside the car stops working, and the smart detection antenna outside the car keeps working, and the IBCM can know in real time whether the legal key is in the effective detection area outside the car. In addition, during the key search, the WCM function is not prohibited;

[0080] In the key search prohibition mode, the search for the key position is stopped and the vehicle-mounted mobile phone wireless charging module (WCM) function is turned on. Specifically, in this mode, the IBCM does not prohibit the WCM function because the key search function is stopped.

[0081] In an embodiment of the present invention, in the low power consumption key search mode, if it is detected that the key re-enters the effective area outside the vehicle, the high power consumption key search mode is returned to, and the timer in the high power consumption key search mode is reset;

[0082] In the low power key search mode, if a door opening operation is detected, the timer in the low power key search mode is reset;

[0083] In the low-power key search mode, if a locking trigger operation on the vehicle door is detected (such as the timing time is reached, or the user long presses the door handle sensor), the vehicle locking and arming operation is executed.

[0084] In a specific example, the vehicle locking and arming operation includes controlling the closing of the door lock motor and starting the vehicle's safety system; during the locking and arming stage, if the alarm is triggered, the vehicle's external discharge is cut off through the vehicle controller (VCU), and an alarm signal is issued through the lights and horn.

[0085] It is understandable that in the embodiments of the present invention, the integrated body control module (IBCM) plays a core management and implementation role in the vehicle control logic of the camping mode. As a key component of the intelligent body control system, the IBCM is responsible for receiving input signals from the sensor system (such as the door AJAR switch, the intelligent detection antenna, etc.), and processing them according to the preset algorithm and logic, and finally issuing control instructions to the actuator (such as the four-door door lock motor, the vehicle-mounted mobile phone wireless charging module, etc.).

[0086] In camping mode, IBCM pays special attention to the location of the key and the safety status of the vehicle. It uses the intelligent detection antenna to send low-frequency electromagnetic waves to search for the location of the smart remote control key, and determines whether the key is within the effective range of the vehicle based on the returned high-frequency signal. At the same time, IBCM also monitors the status of the door and the user's operation behavior to decide when to start or stop the key search and when to perform the automatic locking operation.

[0087] like Figure 3 As shown, a main flow diagram of an embodiment of an intelligent vehicle body control method based on a camping mode provided by the present invention is shown; in this embodiment, it adopts the following Figure 1 , Figure 2 Specifically, the intelligent vehicle body control method comprises the following steps:

[0088] Step S10, after receiving the command to enter the camping mode and detecting that all four doors of the vehicle are closed, starting the high power consumption key search mode to detect the real-time position of the smart remote control key;

[0089] Step S11, according to the detected real-time position of the smart remote control key, select a preset smart vehicle body control strategy to switch the search mode, and determine whether it is necessary to lock and fortify the vehicle body; wherein the position of the smart remote control key is located in the effective area inside the vehicle, within the effective area outside the vehicle, and away from the effective area outside the vehicle;

[0090] In this embodiment, when it is detected that the key has left the effective area, if a door opening operation is detected within a predetermined timing period, the control is not to lock and arm the vehicle body; if no door opening operation is detected within the predetermined timing period, the control is to lock and arm the vehicle body.

[0091] More specifically, in the high power consumption key search mode, if it is detected that the smart remote control key is located in the effective area in the vehicle, it switches to the key search prohibition mode and cancels the locking and arming operation;

[0092] If the smart remote control key is detected to be in the effective area outside the vehicle, the high-power key search mode is maintained, and after the first time, it is switched to the key search prohibition mode, and the locking and arming operation is canceled; if the smart remote control key is detected to be away from the effective area outside the vehicle within the first time, it is switched to the low-power key search mode, and after the second time, the vehicle locking and arming operation is performed;

[0093] If it is detected that the smart remote control key is away from the effective area outside the vehicle, it switches to the low-power key search mode and performs the locking operation after the third time.

[0094] In a specific example, in the high power consumption key search mode, the key positions inside and outside the vehicle are searched at the same time, and the vehicle-mounted mobile phone wireless charging module (WCM) function is turned off;

[0095] In low-power key search mode, only the key position outside the vehicle is searched, and the vehicle-mounted mobile phone wireless charging module (WCM) function is turned on;

[0096] In the key search prohibition mode, the search for the key position is stopped and the vehicle-mounted mobile phone wireless charging module (WCM) function is turned on.

[0097] In a specific example, in the low power consumption key search mode, if it is detected that the key re-enters the effective area outside the vehicle, the high power consumption key search mode is returned to, and the timer in the high power consumption key search mode is reset;

[0098] In the low power key search mode, if a door opening operation is detected, the timer in the low power key search mode is reset;

[0099] In the low-power key search mode, if a door lock trigger operation is detected, the vehicle lock arming operation is performed.

[0100] In a specific example, the vehicle locking and arming operation includes controlling a door lock motor to close and activating a vehicle security system;

[0101] During the locked and armed stage, if the alarm is triggered, the vehicle controller (VCU) will cut off the vehicle's external discharge and send out an alarm signal through the lights and horn.

[0102] For more details, please refer to the above Figure 1 and Figure 2 Description.

[0103] In order to further understand the method provided by the present invention, the following will be combined with Figure 4 The details of the method according to the present invention will be described.

[0104] exist Figure 4 In the example shown, the following steps are included:

[0105] (a) IBCM can determine the open and closed status of the four doors by collecting the door AJAR switches of the four doors. When it is detected that the four doors are closed, the high-power key search mode is entered. Start several consecutive (such as three) key searches inside and outside the vehicle; it can be understood that in this embodiment, the key search mode is not started when the door is not closed, so as to reduce unnecessary energy consumption and avoid the vehicle being locked by mistake when it is not completely closed. At the same time, the use of three consecutive searches is a preliminary screening process in the high-power key search mode, which is used to initialize the key position detection process and is interrelated with the subsequent low-power key search mode and control strategy.

[0106] (ii) If a legitimate key is found in the valid area inside the vehicle, the IBCM enters the key search prohibition mode, restores the WCM function, and the vehicle is not locked; it is understandable that when a legitimate key is left in the vehicle, the IBCM detects that the key is in the valid area inside the vehicle and controls the vehicle not to be locked, so as to avoid the embarrassing situation of the owner being locked out of the vehicle due to forgetting the key.

[0107] (III) If a legitimate key is found in the valid area outside the vehicle, the IBCM will maintain the "high power consumption key search mode" and start a 10-minute timer. During the 10-minute timer, if the key is always in the valid area outside the vehicle, it means that the owner is always near the vehicle, and the WCM will remain in the prohibited state, and the vehicle will not be locked; when the 10-minute timer ends, the IBCM will enter the key search prohibited mode, restore the WCM function, and the vehicle will not be locked;

[0108] If the legitimate key is detected to be missing (away from the valid area) within 10 minutes, the IBCM enters the "low-power key search mode" and starts a 30-minute timer: if the key is found to enter the valid area again within 30 minutes, it returns to the 10-minute "high-power key search mode" state; if the car door is opened within 30 minutes, the 30-minute timer will be restarted; if the 30-minute timer ends or the door handle switch is long pressed within 30 minutes, the lock arming stage will be executed.

[0109] It is understandable that when the user (key holder) leaves the vehicle for a long time (for example, to go hiking or have a picnic), the 30-minute timer is used to determine whether the user has actually left and trigger the vehicle to lock in this case. By setting a longer timing time, it can be ensured that the vehicle can automatically lock when the user actually leaves and will not return immediately, thereby enhancing the safety of the vehicle. In a specific example, the user takes the key to go hiking and is expected to return in 1 hour. After leaving the vehicle, the vehicle starts a 30-minute timing. During this period, if the vehicle detects that the key signal reappears (for example, the user returns to pick up something halfway), the timer will be reset. If the key signal has not appeared within 30 minutes and no door has been opened, the vehicle will automatically lock after the timing ends to ensure the safety of the vehicle.

[0110] At the same time, in this step, setting "restart the 30-minute timer" can provide a "grace period" or "delay period" for the car owner so that they do not have to worry about the vehicle immediately entering the locked and armed state when they leave the vehicle for a short time (such as picking up something, talking to others, etc.). If the car owner opens the door during this period (whether by regular operation or other means), it usually means that the car owner may return to the car or have further operation requirements for the vehicle, so the system will reset the originally set 30-minute timer and start the timer from the beginning. For example, in one example, suppose the car owner is waiting for someone next to the vehicle, but is worried about forgetting to lock the car, so he starts the automatic locking function of the vehicle. However, during the 20 minutes of waiting, the car owner needs to enter the car to pick up an item. When he opens the door and closes it again, the IBCM will detect this operation and automatically invalidate the 20 minutes that have passed before, and restart the 30-minute timer. In this way, the car owner has more time to complete his affairs without having to worry about the vehicle being locked immediately.

[0111] In addition, performing the locking and arming operation after the 30-minute timer ends can ensure that the vehicle can automatically enter the locked and arming state when the owner actually leaves the vehicle and has no intention of further operation, thereby improving the safety of the vehicle.

[0112] The owner can also clearly express his intention to leave and lock the vehicle by long pressing the door handle switch (sensor) within 30 minutes. The IBCM will then execute the locking and arming phase and activate the vehicle's safety protection function.

[0113] (IV) If no legal key is found in the valid area inside or outside the vehicle, the IBCM enters the "low power key search mode" and starts a 10-minute timer. If a legal key is found in the valid area outside the vehicle again within 10 minutes, the IBCM re-enters the "high power key search mode" and starts a 10-minute timer, maintaining the same strategy as in step (III). If the 10-minute timer ends, the IBCM enters the key search prohibition mode, restores the WCM function, and controls the vehicle to not lock.

[0114] (V) When the alarm is triggered during the lock-up defense phase, the VCU is required to cut off external discharge while the lights and horns are sounding. When the vehicle is illegally invaded or operated abnormally, the alarm system (lights, horns) will promptly notify the owner and surrounding personnel to serve as a deterrent. At the same time, when the alarm is triggered during the defense phase, the external discharge is cut off to prevent the vehicle from being illegally used without authorization, resulting in energy waste.

[0115] From the above description, it can be seen that the method of implementing the present invention embodies the balance between security and user experience of the IBCM system. Through the low-power key search mode and the setting of the timer, the system can ensure a certain level of alertness when the key is not within the monitoring range, and avoid unnecessary trouble when the owner is not aware of the key loss. At the same time, restoring the WCM function also ensures the basic operability of the vehicle and the continuity of the user experience.

[0116] The invention solves two common working conditions in outdoor camping scenarios at the same time (users frequently move around in the car or nearby areas and users move away from the vehicle), and can eventually achieve successful intelligent active locking, bringing customers a good user experience. It is understandable that under two different vehicle use conditions, the owner's anti-theft requirements for the vehicle are different: when the user moves around in the area near the vehicle, the vehicle does not need to be locked for anti-theft, meeting the user's frequent getting on and off the vehicle; but when the owner needs to stay away from the vehicle for a long time to carry out activities (light hiking, fishing), the people traveling with him may still move around the vehicle, and on the one hand, it is necessary to facilitate the activities near the vehicle without being affected; on the other hand, when no one is active near the vehicle, the vehicle needs to be locked for anti-theft to reduce the risk of theft, while monitoring the surrounding environment, timely cutting off external discharge, and ensuring outdoor power safety. The present invention can well meet the needs of the above two common working conditions.

[0117] As another aspect of the present invention, there is also provided a computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, the following is achieved: Figure 3 and Figure 4 For more details, please refer to the above Figure 3 and Figure 4 The description is not repeated here.

[0118] Implementing the embodiments of the present invention has the following beneficial effects:

[0119] The present invention proposes an intelligent vehicle body control method, device, system and storage medium based on camping mode. In the embodiment of the present invention, the intelligent locking control logic for camping mode pre-stored in the integrated vehicle body control module is used to optimize the design of the intelligent active locking function for specific scenarios, which can meet the two most common key usage conditions for outdoor camping, and finally can intelligently and actively lock and fortify the vehicle. It can realize non-sensitive vehicle body safety control and improve user experience.

[0120] In the present invention, through the intelligent locking control logic (when it is detected that the key has left the effective area, if someone opens the door during the timing period, the vehicle will not be locked, and other keyless users can use it normally; if no one opens the door during the timing period, it will be controlled to lock), active and passive combined locking defense in the keyless situation is realized; thereby, by optimizing the key search and locking strategy, misjudgment and repeated triggering are reduced, and the user's car experience in camping scenarios is improved. At the same time, it can ensure that the vehicle is automatically locked when the user is away for a long time and there is no one around, preventing the vehicle from being stolen and improving safety.

[0121] The present invention is described with reference to flowcharts and / or block diagrams of methods, devices (systems), and computer program products according to embodiments of the present invention. It should be understood that each process and / or block in the flowchart and / or block diagram, as well as the combination of processes and / or blocks in the flowchart and / or block diagram, can be implemented by computer program instructions.
