Description

Technical Field

[0001] This invention relates to the field of vehicle safety technology, and in particular to a method, device, electronic equipment, storage medium, and program product for unlocking the doors of new energy vehicles. Background Technology

[0002] With the rapid development of new energy vehicles, these vehicles are quickly becoming more widespread due to their advantages such as environmental friendliness and high efficiency. Among them, electric vehicle door locks, as a key component ensuring vehicle safety and convenient use, are becoming increasingly important in terms of performance stability and reliability.

[0003] Current mainstream new energy vehicle door locks generally use a self-spring unlocking method, equipped with a microswitch in the outer handle. When the outer handle is pulled, the microswitch is triggered, and the vehicle control system recognizes the signal, driving the self-spring unlocking motor to open the door. However, current technology is susceptible to abnormal interference in electric vehicles, which can falsely trigger collision unlocking. The accuracy of collision detection is low, causing the vehicle to automatically unlock its doors even when there is no danger. Furthermore, in the event of a collision, the vehicle may lose power, preventing the door locks from unlocking properly. This significantly hinders rescue efforts for occupants from outside the vehicle, resulting in low vehicle safety. Summary of the Invention

[0007] The vehicle collision state of the target vehicle is determined based on the vehicle hardwire signal and the vehicle bus signal, wherein the vehicle collision state includes a collision state and a non-collision state.

[0008] If the current vehicle status is a collision state, an automatic collision unlocking operation is triggered to unlock at least one door lock of the target vehicle.

[0009] According to another aspect of the present invention, a door unlocking device for a new energy vehicle is provided, comprising:

[0035] Example 1

[0036] Figure 1 The flowchart of a method for unlocking the door of a new energy vehicle is provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where the door lock is unlocked based on the vehicle hardwire signal and the vehicle bus signal. The method can be executed by the door unlocking device of the new energy vehicle. The door unlocking device of the new energy vehicle can be implemented in hardware and / or software. Optionally, it can be implemented by an electronic device, such as a mobile terminal, a PC, or a server.

[0037] like Figure 1 As shown, the method may specifically include:

[0038] S110. Acquire the vehicle hardwire signal and vehicle bus signal of the target vehicle, wherein the vehicle hardwire signal is the vehicle collision status signal sent by the airbag system of the target vehicle through the vehicle hardwire, and the vehicle bus signal is the vehicle collision status signal sent by the airbag system through the vehicle bus of the target vehicle.

[0039] The target vehicle can be any vehicle requiring signal acquisition and collision state analysis. For example, a new energy vehicle equipped with an airbag system and related signal transmission functions traveling on the road. By acquiring and analyzing the hardwired and bus signals of the target vehicle, its safety status and other relevant information can be determined.

[0040] Among these, the vehicle hardwire signal can be a vehicle collision status signal sent by the target vehicle's airbag system via the vehicle hardwire. For example, the target vehicle's airbag system uses the physical connection line (vehicle hardwire) to send an electrical signal to the vehicle control unit (such as the door control subunit within the vehicle control unit). The vehicle hardwire signal can include a vehicle collision hardwire signal, a normal non-collision hardwire signal, and an abnormal non-collision hardwire signal.

[0041] Among them, the vehicle collision status signal can be a status signal sent by the airbag system of the target vehicle through the vehicle hardwire or vehicle bus to indicate whether a collision has occurred.

[0042] The "vehicle collision hardwired signal" can be an electrical signal sent via the vehicle hardwired when a collision has occurred to the target vehicle, and the airbag system detects the collision and activates (e.g., deploys the airbags or performs other actions). For example, when a collision occurs, the airbag system sends a square wave signal with a 20% duty cycle to the door control subunit within a preset signal transmission / reception period (the duration of a preset signal transmission / reception period can be 20ms; within this period, the airbag system sends an electrical signal representing the vehicle collision status to the door control subunit via the vehicle bus and vehicle hardwired). The "vehicle normal no-collision hardwired signal" can be an electrical signal sent via the vehicle hardwired when no collision has occurred to the target vehicle and the airbag system has not detected a collision. For example, when the target vehicle is in a normal state and no collision has occurred, the airbag system sends a square wave signal with an 80% duty cycle to the door control subunit within a 20ms period. An abnormal non-collision hardwire signal can be an electrical signal transmitted by the airbag system through the vehicle's hardwire when no collision has occurred, which does not conform to the characteristics of a normal non-collision state signal. For example, an abnormal non-collision hardwire signal can be a hardwire collision waveform with abnormalities, such as continuously sending a high level or continuously sending a low level, which are abnormal non-collision waveform electrical signals.

[0043] Among these, vehicle bus signals can be vehicle collision status signals sent by the airbag system through the target vehicle's vehicle bus. For example, the target vehicle's airbag system uses the target vehicle's vehicle bus (the target vehicle's CAN bus (Controller Area Network)) to send electrical signals characterizing the vehicle's collision status to the vehicle control unit (such as the door control subunit within the vehicle control unit that controls door opening and closing). Vehicle bus signals can include vehicle collision-already bus signals, vehicle airbag node information loss signals, and vehicle no-collision message signals.

[0044] The vehicle collision bus signal can be a data signal sent via the vehicle bus when the target vehicle has been involved in a collision, the airbag system detects the collision and triggers (e.g., the airbags deploy). The vehicle no-collision message signal can be an electrical signal sent via the vehicle bus by the airbag system within a preset signal transmission / reception period (e.g., 20ms) when the target vehicle is driving normally. The vehicle airbag node information loss signal can be an airbag node loss signal generated by the target vehicle's signal receiving unit (e.g., the door control subunit in the vehicle control unit) when it fails to receive either the vehicle collision bus signal or the vehicle no-collision message signal sent by the airbag system via the vehicle bus for one or more consecutive preset signal transmission / reception periods (e.g., 1 preset signal transmission / reception period, 5 consecutive preset signal transmission / reception periods, or 10 consecutive preset signal transmission / reception periods). For example, if the door control subunit of the target vehicle does not receive either the vehicle collision bus signal or the vehicle non-collision message signal sent by the airbag system via the vehicle bus during one or more preset signal transmission cycles, it can send a warning signal to the airbag system. The airbag system then generates an airbag node loss signal based on the received warning signal and sends it to the door control subunit. In another scenario, the door control subunit can also directly generate an airbag node loss signal based on the airbag system's signal loss status, thereby improving the door lock unlocking efficiency.

[0045] Specifically, acquiring the vehicle hardwire signal and vehicle bus signal of the target vehicle can be achieved by the target vehicle's airbag system generating a vehicle collision state signal (i.e., vehicle hardwire signal and vehicle bus signal) corresponding to each preset signal transmission and reception cycle based on the target vehicle's collision state. The vehicle hardwire signal generated in each preset signal transmission and reception cycle is then sent to the vehicle control unit (such as the door control subunit in the vehicle control unit) via the vehicle hardwire, and the vehicle bus signal generated in each preset signal transmission and reception cycle is also sent to the vehicle control unit (such as the door control subunit in the vehicle control unit) via the vehicle bus. The vehicle control unit can determine whether a collision has occurred based on the vehicle bus signal and vehicle hardwire signal received in each preset signal transmission and reception cycle.

[0046] S120. Determine the vehicle collision state of the target vehicle based on the vehicle hardwire signal and the vehicle bus signal, wherein the vehicle collision state includes a collision state and a non-collision state.

[0047] The vehicle collision state can be determined based on vehicle hardwired signals and vehicle bus signals, indicating whether a collision has occurred with the target vehicle. The vehicle collision state includes a collided state and a non-collision state. The collided state indicates that the target vehicle is currently in a collision state, while the non-collision state indicates that the target vehicle is currently not in a collision state.

[0048] Specifically, determining the collision state of a target vehicle based on vehicle hardwire signals and vehicle bus signals can be achieved by first acquiring these signals and then combining them to determine whether the vehicle is currently in a collision state. The door locks can then be controlled based on this collision state. Determining the collision state by combining both hardwire and bus signals improves the accuracy of collision state assessment and enhances vehicle safety.

[0049] Specifically, determining the vehicle collision state of the target vehicle based on the vehicle hardwire signal and the vehicle bus signal includes: determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal and the vehicle bus signal meet a first preset condition.

[0050] The first preset condition can be a pre-defined condition used to characterize the target vehicle's collision state as a collision state. The first preset condition includes at least one of the following: the vehicle hardwire signal is a collision hardwire signal and the vehicle bus signal is a first bus signal, the first bus signal including a collision bus signal, a vehicle airbag node information loss signal, and a vehicle non-collision message signal; the vehicle hardwire signal is a normal non-collision hardwire signal and the vehicle bus signal is a collision bus signal; the vehicle hardwire signal is an abnormal non-collision hardwire signal and the vehicle bus signal is a second bus signal, the second bus signal including the collision bus signal and the vehicle airbag node information loss signal.

[0051] Specifically, determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal and the vehicle bus signal meet the first preset condition may include: determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal is a vehicle collision hardwire signal and the vehicle bus information is a vehicle collision bus signal.

[0052] Specifically, determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal and the vehicle bus signal meet the first preset condition may further include: determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal is a vehicle collision hardwire signal and the vehicle bus information is a vehicle airbag node information loss signal.

[0053] For example, if the vehicle hardwire signal received by the door controller subunit is a vehicle collision hardwire signal, and neither the vehicle collision bus signal nor the vehicle non-collision message signal is received during one or more preset signal transmission and reception cycles, the airbag safety system or the door controller subunit can generate a vehicle airbag node information loss signal and send it to the door controller subunit. The door controller subunit can determine that the vehicle collision state is a collision state based on the vehicle collision hardwire signal and the vehicle airbag node information loss signal. This can prevent the door controller subunit from misjudging the vehicle collision when it fails to receive the message sent by the airbag system due to abnormal interference with the vehicle bus, thereby improving the accuracy of the vehicle collision state judgment and enhancing vehicle safety.

[0054] Specifically, determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal and the vehicle bus signal meet the first preset condition may further include: determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal is a vehicle collision hardwire signal and the vehicle bus information is a vehicle non-collision message signal.

[0055] Specifically, determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal and the vehicle bus signal meet the first preset condition may further include: determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal is a normal, non-collision hardwire signal and the vehicle bus signal is a collision-already bus signal.

[0056] Specifically, determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal and the vehicle bus signal meet the first preset condition may further include: determining the vehicle collision state of the target vehicle as a collision state when the vehicle hardwire signal is a vehicle abnormal non-collision hardwire signal and the vehicle bus signal is a vehicle collision bus signal.

[0057] Specifically, when the vehicle hardwire signal and the vehicle bus signal meet the first preset condition, determining the vehicle collision state of the target vehicle as a collision state may also include: when the vehicle hardwire signal is a vehicle abnormal non-collision hardwire signal and the vehicle bus signal is a vehicle airbag node information loss signal, determining the vehicle collision state of the target vehicle as a collision state.

[0058] Specifically, determining the vehicle collision state of the target vehicle based on the vehicle hardwire signal and the vehicle bus signal also includes: determining the vehicle collision state of the target vehicle as a non-collision state when the vehicle hardwire signal and the vehicle bus signal meet the second preset condition.

[0059] The second preset condition can be a pre-set condition used to characterize the target vehicle's collision state as a non-collision state. The second preset condition includes at least one of the following: the vehicle hardwire signal is a normal non-collision hardwire signal and the vehicle bus signal is a third bus signal, the third bus signal including a vehicle airbag node information loss signal and a vehicle non-collision message signal; the vehicle hardwire signal is a hardwire abnormal non-collision signal and the vehicle bus signal is a non-collision message signal.

[0060] Specifically, determining the target vehicle's collision state as non-collision state when the vehicle hardwire signal and vehicle bus signal meet the second preset conditions may include: determining the target vehicle's collision state as non-collision state when the vehicle hardwire signal is a normal non-collision hardwire signal and the vehicle bus signal is a signal indicating that the vehicle airbag node information has been lost.

[0061] Specifically, determining the target vehicle's collision state as non-collision state when the vehicle hardwire signal and vehicle bus signal meet the second preset conditions may include: determining the target vehicle's collision state as non-collision state when the vehicle hardwire signal is a normal non-collision hardwire signal and the vehicle bus signal is a non-collision message signal.

[0062] Specifically, determining the target vehicle's collision state as non-collision state when the vehicle hardwire signal and vehicle bus signal meet the second preset conditions may include: determining the target vehicle's collision state as non-collision state when the vehicle hardwire signal is a hardwire abnormal non-collision signal and the vehicle bus signal is a non-collision message signal.

[0063] S130. If the current vehicle status is a collision state, trigger an automatic collision unlocking operation to unlock at least one door lock of the target vehicle.

[0064] The automatic collision unlocking operation can be initiated when the door control subunit determines that the target vehicle is in a collision state based on vehicle bus signals and vehicle hardwire signals. In this case, the vehicle control unit automatically issues a command to unlock one or more doors of the vehicle and drives the door locks to perform the unlocking operation accordingly. The door locks can be mechanical or electronic devices installed on the target vehicle doors to control the opening and locking of the vehicle doors.

[0065] Specifically, when the current vehicle status is a collision state, an automatic collision unlocking operation is triggered to unlock at least one door lock of the target vehicle. This can be achieved by the vehicle control unit of the target vehicle controlling one or more door locks on the target vehicle to change from the current locked state to the unlocked state when the current vehicle status of the target vehicle is a collision state.

[0066] Optionally, after triggering the automatic collision unlocking operation to unlock at least one door lock of the target vehicle, if the operation time of the automatic collision unlocking operation exceeds a preset time, the automatic collision unlocking operation can be executed again. By re-executing the automatic collision unlocking operation if the operation time exceeds the preset time, it can be ensured that the vehicle doors are opened in the event of a collision, avoiding difficulties in rescue and escape caused by the doors not being able to unlock properly after a collision, thereby improving vehicle safety. The preset time can be 3 seconds or 5 seconds.

[0067] The technical solution of this invention obtains the vehicle hardwire signal transmitted by the airbag system of the target vehicle through the vehicle hardwire and the vehicle bus signal transmitted by the airbag system through the vehicle bus of the target vehicle. Based on the vehicle hardwire signal and the vehicle bus signal, the collision state of the target vehicle is determined, wherein the collision state includes a collision state and a non-collision state. When the current vehicle state is a collision state, an automatic collision unlocking operation is triggered to unlock at least one door lock of the target vehicle. This can improve the accuracy of vehicle collision unlocking recognition and enhance the driving safety of users.

[0068] Example 2

[0069] Figure 2 This is a flowchart of a method for unlocking the door of a new energy vehicle according to Embodiment 2 of the present invention. Based on the above embodiments, this embodiment adds a technical feature of unlocking the door via a door trigger signal when the current vehicle state meets preset unlocking conditions and the target vehicle fails to unlock. Optionally, when the current vehicle state meets preset unlocking conditions and the target vehicle fails to unlock, a door trigger signal of at least one door of the target vehicle is obtained; if the door trigger signal meets preset mechanical unlocking conditions, an automatic mechanical unlocking operation is triggered to unlock the door lock of the target vehicle. Detailed implementation methods can be found in the description of this embodiment. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here. Figure 2 As shown, the method may specifically include:

[0070] S210. Acquire the vehicle hardwire signal and vehicle bus signal of the target vehicle, wherein the vehicle hardwire signal is the vehicle collision status signal sent by the airbag system of the target vehicle through the vehicle hardwire of the target vehicle, and the vehicle bus signal is the vehicle collision status signal sent by the airbag system through the vehicle bus of the target vehicle.

[0071] S220. Determine the vehicle collision state of the target vehicle based on the vehicle hardwire signal and the vehicle bus signal, wherein the vehicle collision state includes a collision state and a non-collision state.

[0072] S230. If the current vehicle status is a collision state, trigger an automatic collision unlocking operation to unlock at least one door lock of the target vehicle.

[0073] S240. If the current vehicle status meets the preset unlocking conditions and the target vehicle fails to unlock, obtain the door trigger signal of at least one door of the target vehicle.

[0074] The door trigger signal can be a trigger operation received by the vehicle door to open or unlock when the current vehicle status meets the preset unlocking conditions and the target vehicle fails to unlock. Door trigger signals include vehicle exterior handle trigger signals, vehicle interior door / door switch trigger signals, and child lock unlock signals.

[0075] The vehicle exterior door handle trigger signal can be an electrical signal generated when an external person pulls the door handle from the outside of the vehicle, triggering a microswitch or sensor installed inside the door handle, provided the current vehicle status meets preset unlocking conditions and the target vehicle fails to unlock. The vehicle interior door handle trigger signal can be an electrical signal generated when an internal person pulls the door handle switch from the inside of the vehicle, causing contacts inside the door handle switch to close or open, provided the current vehicle status meets preset unlocking conditions and the target vehicle fails to unlock. The child lock unlock signal can be a signal generated when an internal person attempts to unlock the child lock device on the door, provided the current vehicle status meets preset unlocking conditions and the target vehicle fails to unlock. The child lock of the target vehicle can be a dedicated switch or knob installed on the edge of the door.

[0076] Specifically, when the current vehicle status meets the preset unlocking conditions and the target vehicle fails to unlock, the system acquires a door trigger signal from at least one door of the target vehicle. This could be achieved when the current vehicle status is in a collision state and the door locks of the target vehicle fail to unlock, by acquiring a signal from an inside person triggering the inside door handle or an outside person triggering the outside door handle. Based on this signal, the system determines whether to perform subsequent automatic mechanical unlocking operations. This avoids dangerous situations caused by doors failing to unlock properly after a collision, thereby improving the efficiency of rescuing passengers inside the collided vehicle and enhancing the safety of passengers inside the vehicle.

[0077] S250: When the door trigger signal meets the preset mechanical unlocking conditions, an automatic mechanical unlocking operation is triggered to unlock the door lock of the target vehicle.

[0078] The preset mechanical unlocking conditions can be pre-set and are used to determine whether to trigger the automatic mechanical unlocking operation. The preset mechanical unlocking conditions include at least one of the following: the duration of the vehicle's external handle trigger signal exceeds a first preset duration; the duration of the vehicle's interior door switch trigger signal exceeds a second preset duration; the duration of the child lock unlocking signal exceeds a third preset duration. The first preset duration can be a pre-set time threshold for the external handle trigger signal to meet the preset mechanical unlocking conditions, representing the shortest continuous operation time for the external handle trigger signal to meet the preset mechanical unlocking conditions. For example, the first preset duration can be set to 40 milliseconds or 50 milliseconds. The second preset duration can be a pre-set time threshold for the vehicle's interior door switch trigger signal to meet the preset mechanical unlocking conditions, representing the shortest continuous operation time for the interior door switch trigger signal to meet the preset mechanical unlocking conditions. For example, the second preset duration can be set to 30 milliseconds or 50 milliseconds. The third preset duration can be a pre-set time threshold for the child lock unlocking signal to meet the preset mechanical unlocking conditions, representing the shortest continuous operation time for the child lock unlocking signal to meet the preset mechanical unlocking conditions. For example, the third preset duration can be set to 10 milliseconds or 20 milliseconds. Automatic mechanical unlocking is a door unlocking operation that is automatically performed by the vehicle after detecting a valid unlocking signal.

[0079] Specifically, when the door trigger signal meets preset mechanical unlocking conditions, an automatic mechanical unlocking operation is triggered to unlock the target vehicle's door lock. This can be achieved when the duration of the external door handle trigger signal exceeds a first preset duration, the duration of the internal door switch trigger signal exceeds a second preset duration, or the duration of the child lock unlocking signal exceeds a third preset duration. By triggering the automatic mechanical unlocking operation when the door trigger signal meets the preset mechanical unlocking conditions, the unlocking efficiency of the target vehicle after a collision can be further improved, increasing the unlocking speed and thus enhancing rescue efficiency.

[0080] Optionally, after triggering the automatic mechanical unlocking operation, the method further includes: if the unlocking time of unlocking the door lock of the target vehicle according to the automatic mechanical unlocking operation is longer than the preset unlocking time, performing the automatic mechanical unlocking operation again to unlock the door lock of the target vehicle.

[0081] The door lock unlocking time can be the time elapsed after the automatic mechanical unlocking operation is performed. The preset unlocking time can be a pre-defined time threshold for re-performing the automatic mechanical unlocking operation. For example, the preset unlocking time can be set to 3 seconds or 5 seconds.

[0082] Specifically, if the unlocking time of the target vehicle's door lock according to the automatic mechanical unlocking operation is longer than the preset unlocking time, the automatic mechanical unlocking operation is executed again to unlock the target vehicle's door lock. This can be achieved by timing the unlocking time of the target vehicle's door lock after the automatic mechanical unlocking operation, and then executing the automatic mechanical unlocking operation again if the unlocking time of the target vehicle's door lock is longer than the preset unlocking time. This avoids situations where the door cannot be opened normally after a vehicle collision, thereby improving rescue efficiency and enhancing the safety of the occupants inside the vehicle.

[0083] The technical solution of this invention obtains the vehicle hardwire signal transmitted by the airbag system of the target vehicle through the vehicle hardwire and the vehicle bus signal transmitted by the airbag system through the vehicle bus of the target vehicle. Based on the vehicle hardwire signal and the vehicle bus signal, the collision state of the target vehicle is determined, where the collision state includes a collision state and a non-collision state. If the current vehicle state is a collision state, an automatic collision unlocking operation is triggered to unlock at least one door lock of the target vehicle, which improves the accuracy of vehicle collision unlocking recognition and enhances user safety. Furthermore, if the current vehicle state meets preset unlocking conditions and the target vehicle fails to unlock, a door trigger signal from at least one door of the target vehicle is obtained. If the door trigger signal meets preset mechanical unlocking conditions, an automatic mechanical unlocking operation is triggered to unlock the door lock of the target vehicle, further improving vehicle safety.

[0084] Example 3

[0085] Figure 3 This is a schematic diagram of the structure of a door unlocking device for a new energy vehicle provided in Embodiment 3 of the present invention. Figure 3 As shown, the device includes: a signal acquisition module 310, a vehicle status determination module 320, and an unlocking module 330.

[0086] The signal acquisition module 310 is used to acquire the vehicle hardwire signal and vehicle bus signal of the target vehicle. The vehicle hardwire signal is the vehicle collision status signal transmitted by the airbag system of the target vehicle through the vehicle hardwire, and the vehicle bus signal is the vehicle collision status signal transmitted by the airbag system through the vehicle bus. The vehicle status determination module 320 is used to determine the vehicle collision status of the target vehicle based on the vehicle hardwire signal and the vehicle bus signal. The vehicle collision status includes a collision state and a non-collision state. The unlocking module 330 is used to trigger an automatic collision unlocking operation to unlock at least one door lock of the target vehicle when the current vehicle status is a collision state.
