Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle control method and device. Background Art

[0002] At present, the popularity of cars has brought great convenience to people's travel, and they are increasingly widely used in people's lives and work. At the same time, there are also some accidents caused by improper use of cars. For example, parents forget their children in a closed vehicle and lock the car and leave. The children cannot notify their parents in time. After a long time, the temperature in the car rises or lack of oxygen will cause dehydration and shock, or even death. Therefore, in order to reduce the occurrence of accidents, effective detection of occupants in the vehicle is still an important issue that needs to be solved urgently. Summary of the invention

[0003] The embodiments of the present application provide a vehicle control method and device for improving the detection accuracy of occupants in a vehicle to reduce accidents.

[0004] In the first aspect, the embodiment of the present application provides a vehicle control method, which can be implemented by a vehicle control device, which can be an independent device, a chip or component in a device, or software. The vehicle control device can be deployed in any of the cloud, the vehicle side, or a third-party device. Correspondingly, the vehicle control device can be deployed in a server, a controller in a vehicle (such as a body controller, a vehicle domain controller, etc.), or an electronic control unit (ECU) in a vehicle. Alternatively, the vehicle control device can be a newly added hardware module in the vehicle, which can be configured with relevant judgment logic or algorithms, and can be used as an ECU in the vehicle, and transmit information with other ECUs through an internal communication network to implement the vehicle control method of the embodiment of the present application. The embodiment of the present application does not limit the product form or deployment method of the vehicle control device.

[0005] The vehicle control method may include: determining that a physical state of at least one component of a vehicle has changed; determining that there is an occupant in the vehicle based on first information, wherein the first information is associated with the physical state change of at least one component of the vehicle; determining that a door lock of the vehicle is in a locked state; and sending a first alarm message to a user equipment UE, wherein the first alarm message is used to indicate that the door lock is in a locked state and there is an occupant in the vehicle.

[0006] Through the above method, the vehicle control device can identify whether there are forgotten passengers in the vehicle by monitoring the physical status of vehicle components and the status of door locks, and promptly send an alarm to the user device of the vehicle user to rescue the passengers trapped in the vehicle in time, thereby reducing accidents.

[0007] In one possible implementation, the vehicle control device may communicate directly with the at least one component via a cable, and determining that a physical state of at least one component of the vehicle has changed includes: upon receiving an electrical signal from the at least one component, determining that a physical state of the at least one component has changed.

[0008] In a possible implementation manner, if the vehicle control device is in a dormant state, the method further includes: waking up the vehicle control device upon receiving an electrical signal from the at least one component.

[0009] Through the above method, the vehicle control device can be dormant and awakened to control the vehicle when the physical state of any component of the vehicle changes. The vehicle control device does not need to work continuously, has no effect on the power consumption of the entire vehicle, and is more energy-efficient than continuously monitoring the status of the vehicle, which helps to increase the robustness of the entire vehicle system.

[0010] In a possible implementation, the first information is used to characterize that the vehicle is in a first state, the first state being a state in which there are passengers in the vehicle, the first state being obtained based on a change in the physical state of at least one component of the vehicle, and the method further includes: acquiring the first information from a non-volatile storage medium of the vehicle.

[0011] Through the above method, the vehicle control device can determine the presence status of the occupant in the vehicle by obtaining the first information from the non-volatile storage medium of the vehicle without the need for further analysis, which helps to reduce the detection time.

[0012] In one possible implementation, the first information is used to characterize a change in a physical state of at least one component of the vehicle, and the method further includes: if there are occupants in the vehicle and the doors of the vehicle are closed, recording second information in a non-volatile storage medium of the vehicle, wherein the second information is used to characterize that the vehicle is in a first state, and the first state is a state in which there are occupants in the vehicle.

[0013] Through the above method, the vehicle control device can latch the presence status of the occupant in the vehicle when there is an occupant in the vehicle and the door of the vehicle is closed, so that when the vehicle controller is awakened, the presence status of the occupant in the vehicle can be determined by obtaining the first information from the vehicle's non-volatile storage medium without the need for further analysis, which helps to reduce detection time.

[0014] In a possible implementation, the method may further include: when the door of the vehicle changes from closed to open, clearing the second information from the non-volatile storage medium of the vehicle. Optionally, the vehicle control device may also repeatedly implement the method described above after the second information is cleared to monitor the presence status of the occupants in the vehicle in real time, so as to issue corresponding warnings to the user and reduce safety accidents.

[0015] In a possible implementation manner, determining that the door lock of the vehicle is in the locked state includes: upon receiving a vehicle locking control signal, determining that the door lock of the vehicle is in the locked state.

[0017] In a possible implementation, the method may further include: sending second warning information to the UE, where the second warning information is used to indicate the autonomous control capability of the occupant in the vehicle over at least one component of the vehicle.

[0018] Through the above method, the vehicle control device can identify the specific scenario in which the occupants in the vehicle are located to determine whether the occupants in the vehicle have the ability to autonomously operate certain vehicle components, and send a second alarm message to the user device so that the user can unlock the door or open the door, thereby assisting the occupants in the vehicle to freely enter and exit the vehicle to reduce accidents.

[0059] When implementing the vehicle control method of the embodiment of the present application, the vehicle control device can determine the presence status of the occupant in the vehicle by monitoring whether the physical state of at least one vehicle component has changed. In one possible implementation, the at least one vehicle component can be a physical component inside the vehicle that can be directly touched by the occupant, such as a switch-type component. Exemplarily, the switch-type component can include, but is not limited to: a window switch, a door switch, a seat switch, a seat belt buckle, a seat occupancy sensor switch, an accelerator pedal, a brake pedal, a steering wheel paddle, a shift paddle, a steering wheel angle sensor, an air conditioning button, a start switch, a glove box switch, a sunroof switch, a ceiling light switch, etc.

[0060] 5. The physical state of vehicle components changes:

[0061] The physical state of a vehicle component can be used to describe the physical form of the vehicle component.

[0062] Taking the vehicle component as the above-mentioned switch component as an example, the physical state of the vehicle component may include the open state or the closed state of the switch component. The change in the physical state of the vehicle component may include the switch component changing from the open state to the closed state, or may include the switch component changing from the closed state to the open state.

[0063] In other embodiments, if the presence status of the occupants in the vehicle is monitored by vehicle components other than switch-type components, correspondingly, the change in the physical state of the vehicle component may also refer to other types of changes, which will not be elaborated here.

[0064] 6. Door lock status:

[0065] At present, the doors of vehicles are equipped with door locks to reduce the theft of vehicles. The door lock state generally refers to whether the door lock of the vehicle is locked or unlocked. In the unlocked state, the door can be opened. In the locked state, the door cannot be opened.

[0066] Some common ways to lock your car are as follows:

[0067] (1) Manual locking: Most vehicles are equipped with a manual locking system. Inside the vehicle, passengers can lock the door by pressing the lock button on the door or manually rotating the lock knob on the door. Usually, the lock knob on the door will have a lock icon and an unlock icon. Passengers only need to press the button with the lock icon to lock the door. Press the unlock icon button to unlock the door.

[0068] (2) Remote control locking: Many models of vehicles are also equipped with a remote control locking system. Users can use the remote control key or the remote control button inside the car to lock or unlock the car doors. Similarly, the remote control key will have a lock button and an unlock button. Users only need to press the lock button and the car doors will automatically lock. Press the unlock button and the car doors will automatically unlock.

[0069] (3) Smart Locking: Some high-end vehicles may also be equipped with a smart locking system, which allows users to lock the car door through a mobile phone application or a button on the door handle. Using the smart locking system, users can remotely lock or unlock the car. In some embodiments, users can also set a timed locking function through the smart locking system.

[0070] (4) Automatic locking: Some high-end vehicles may also be equipped with an automatic locking function, that is, when the car key leaves the vehicle at a certain distance, the door locks will automatically lock, without the need for the user to manually control certain buttons or devices to lock the vehicle. When the car key enters a specified range near the vehicle, the door locks will automatically unlock, and the user does not need to manually control certain buttons or devices to unlock the door. In some embodiments, the automatic locking function can be provided by a keyless system (Passive-Entry-Passive-Start, PEPS) on the vehicle.

[0071] When implementing the vehicle control method of the embodiment of the present application, it is only necessary to identify whether the door lock state is a locked state or an unlocked state, and the locking method is not limited.

[0072] 7. Automotive bus:

[0073] A multiplexed communication network technology that can be used to transmit information between multiple electronic control units (ECUs) in a vehicle to form a local area network inside the vehicle. Current automotive buses mainly include: controller area network (CAN) bus, local interconnect network (LIN) bus, high-speed fault-tolerant network protocol (FlexRay) bus, Media Oriented Systems Transport (MOST) bus for automotive multimedia and navigation, and Bluetooth, wireless local area network (such as Ethernet) compatible with computer networks, etc.

[0074] In the embodiment of the present application, the communication methods supported between different components inside the vehicle may include but are not limited to any one of CAN, LIN or Ethernet.

[0075] 8. Vehicle power on:

[0076] Typically, the vehicle's body controller (or a vehicle controller, or a vehicle domain controller, or other devices with body controller functions, which are not limited in the embodiments of the present application) can be connected to relevant low-voltage components on the vehicle through on-board cables (or circuit pins, etc.) to control these low-voltage components, such as the switch components in the vehicle described above. If the body controller is dormant, when these components are operated by the occupants in the vehicle, a wake-up signal will be sent to the body controller to wake up the body controller so that the body controller can control these low-voltage components. In the embodiments of the present application, this behavior is referred to as powering on the vehicle.

[0077] In specific implementation, the above-mentioned low-voltage components may include but are not limited to components of the following systems of the vehicle: ignition switch and grounding, lighting system, air conditioning control system. The specific components included in each system can be found in the introduction of vehicle components in the previous text, which will not be repeated here.

[0078] The embodiments of the present application provide a vehicle control method and device for detecting occupants in a vehicle to reduce accidents. The method and the device are based on the same technical concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated. In addition, in each embodiment of the present application, if there is no special explanation and logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form a new embodiment according to their internal logical relationship.

[0079] The vehicle control scheme in the embodiment of the present application can be applied to the Internet of Vehicles, such as vehicle to everything (V2X), long-term evolution-vehicle (LTE-V), vehicle to vehicle (V2V), etc. For example, it can be applied to a vehicle with a driving mobile function, or other devices in a vehicle with a driving mobile function. The other devices include but are not limited to: other sensors such as a vehicle-mounted terminal, a vehicle-mounted control unit, a vehicle-mounted module, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip, a vehicle-mounted unit, a vehicle-mounted radar or a vehicle-mounted camera.

Of course, the control scheme in the embodiment of the present application can also be used for other intelligent terminals with mobile control functions other than the vehicle, or be set in other intelligent terminals with mobile control functions other than the vehicle, or be set in a component of the intelligent terminal. The intelligent terminal can be an intelligent transportation device, a smart home device, a robot, etc. For example, it includes but is not limited to a smart terminal or a control unit in a smart terminal, a chip, other sensors such as a radar or a camera, and other components.

[0080] In the embodiments of the present application, "at least one" refers to one or more, and "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, c can be single or multiple.

[0081] Furthermore, unless otherwise specified, ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish between multiple objects and are not used to limit the priority or importance of multiple objects.

[0082] The embodiments of the present application are introduced below in conjunction with the accompanying drawings.

[0083] Figure 1 A schematic diagram of an application scenario applicable to the embodiment of the present application is shown. In the application scenario, a vehicle 100 and a user device 300 may be included. The user device 300 may be a mobile phone or a tablet computer as described above, etc., which is not limited in the embodiment of the present application. In a possible implementation, the application scenario may also include a cloud server 200, and the vehicle 100 and the cloud server 200 may communicate via a network. In one embodiment, the cloud server 200 may also be implemented by a virtual machine.

[0084] Some or all functions of the vehicle 100 are controlled by a computing platform 150 (or computer system). The computing platform 150 may include at least one processor 151, which may execute instructions 153 stored in a non-transitory computer-readable medium such as a memory 152. In some embodiments, the computing platform 150 may also be a plurality of computing devices that control individual components or subsystems of the vehicle 100 in a distributed manner. The processor 151 may be any conventional processor, such as a central processing unit (CPU). Alternatively, the processor 151 may also include a graphics processing unit (GPU), a field programmable gate array (FPGA), a system on chip (SoC), an application specific integrated circuit (ASIC), or a combination thereof.

[0085] Optionally, the vehicle 100 may be a car, a truck, a motorcycle, a bus, a ship, an airplane, a helicopter, a lawn mower, an amusement vehicle, an amusement park vehicle, construction equipment, a tram, a golf cart, a train, etc., which is not particularly limited in the embodiments of the present application. In a possible implementation, the vehicle 100 may be a new energy vehicle, which is not limited in the embodiments of the present application.

[0086] It should be noted that Figure 1 The computing platform 150 shown in the figure is only an example of a device for implementing a computing function on the vehicle side and is not intended to be limiting. Figure 1 The structure of the vehicle should not be understood as a limitation to the embodiments of the present application.

[0087] The vehicle control method of the embodiment of the present application can be implemented by a vehicle control device, which can be an independent device or a Figure 1 The chip or component in the vehicle 100 shown can also be a software module, which can be deployed on the relevant on-board equipment of the vehicle 100. The embodiment of the present application does not limit the product form and deployment method of the vehicle control device. In the following, for the sake of ease of understanding and description, the vehicle control device will be introduced as a body controller (body control module, BCM) of the computing platform 150 integrated in the aforementioned vehicle 100. In other embodiments, the body controller can also work in conjunction with other control systems of the vehicle (such as anti-skid system, traction control system, etc.) to provide more comprehensive operating performance. With the continuous advancement of automotive electronic technology, the functions of the body controller can also become more and more powerful, for example, it can be implemented as an intelligent driving domain control unit (such as a mobile data center (mobiledata center, MDC)), or a vehicle control unit (vehicle control unit, VCU), or a vehicle domain control unit (vehicle domain controller, VDC), etc., which will not be repeated here.

[0088] Figure 2 The flow chart of the vehicle control method of the embodiment of the present application is shown. The method can be implemented by a vehicle control device, which can be integrated in Figure 1 The computing platform 150 shown may specifically be a vehicle body controller integrated in the computing platform 150 , or other devices capable of implementing similar functions, which is not limited in the embodiments of the present application.

[0089] See also Figure 2 As shown, the method may include the following steps:

[0090] S210: The vehicle control device determines that a physical state of at least one component of the vehicle changes.

[0091] In the embodiment of the present application, at least one component of the vehicle may be a physical component inside the vehicle that can be directly touched by the occupants, such as a switch component. Figure 3As shown, the switch components may include but are not limited to: window switches, door switches, seat switches, seat belt buckles, seat occupancy sensor switches, accelerator pedals, brake pedals, steering wheel levers (such as wiper switches, low beam switches, high beam switches, etc.), shift levers or buttons, steering wheel angle sensors, air conditioning buttons, start switches, glove box switches, sunroof switches, ceiling light switches, etc. It should be understood that in other embodiments, the above components may also be replaced with other physical components that can be touched by passengers in the vehicle, which will not be described in detail here.

[0092] When S210 is implemented, the vehicle control device may communicate and interact with at least one component of the vehicle through the in-vehicle communication network to determine whether a physical state of at least one component of the vehicle has changed.

[0093] In one example, the vehicle control device can communicate directly with certain components of the vehicle through cables inside the vehicle. For example, the vehicle's ceiling light switch, door lock switch, sunroof switch and other components can be connected to the body controller through cables. When the physical state of these vehicle components changes, the relevant state changes can be reported to the body controller in the form of electrical signals. As long as the body controller receives the electrical signal, it can be considered that the physical state of the corresponding component has changed. The body controller can be used as a vehicle control device in an embodiment of the present application. When receiving an electrical signal from at least one component, it determines that the physical state of at least one component has changed.

[0094] In another example, limited by the arrangement of the vehicle wiring harness, the switch signal indicating the change in the physical state of certain components of the vehicle can be first collected by the controller (for example, represented as the first controller) that is deployed closest to these components, and the first controller can inform the body controller of the change in the physical state of these components through a network signal (such as CAN / LIN / Ethernet, etc.). The body controller can be used as a vehicle control device in an embodiment of the present application, and when receiving a network signal from the first controller, it determines that the physical state of at least one component has changed. Among them, for different vehicle components, different controllers can collect signals indicating changes in the physical states of different components, and the embodiments of the present application are not limited to this.

[0095] The implementation timing of the above S210 can be any time. For example, it can be when the vehicle control device is in a powered-on state, such as after the vehicle is ignited and powered on, or it can be when the vehicle is turned off but the driver has not left the vehicle. Or it can be when the vehicle control device is in a dormant state, such as after the occupant leaves and the vehicle is locked. After implementing S210 at different times, the vehicle control device can implement different controls on the vehicle. Since the embodiments of the present application mainly focus on whether there are occupants left after the vehicle is locked, the following description will mainly introduce possible behaviors before and after the vehicle is locked, and the corresponding control strategies.

[0096] S220: The vehicle control device determines the presence of an occupant in the vehicle based on first information, wherein the first information is associated with a change in the physical state of at least one component of the vehicle.

[0097] In one example, if the vehicle control device implements S210 when it is in a powered-on state, then when implementing S220, the first information is used to characterize a change in the physical state of at least one component of the vehicle. For example, the first information is information about the change in the physical state of at least one component. The vehicle control device can determine the presence of an occupant in the vehicle based on the first information.

[0098] For example, the at least one component may include at least one seat occupancy sensor of the vehicle, and the vehicle control device may determine whether there is an occupant in the corresponding seat of the vehicle based on whether the occupancy state of any seat occupancy sensor changes (for example, from occupied to unoccupied, or from unoccupied to occupied).

[0099] Or for example, the at least one component may include at least one seat belt buckle, and the vehicle control device may determine whether there is an occupant in the corresponding seat of the vehicle based on whether the state of any seat belt buckle changes (for example, from a used state to an unused state, or from an unused state to a used state).

[0100] Or for example, the at least one component may include at least one window switch, and the vehicle control device can determine whether there is an occupant in the corresponding seat of the vehicle based on whether the state of any window switch changes (for example, from the window open to the window closed, or from the window closed to the window open).

[0101] In this case, the vehicle control device can also detect the state of the vehicle door. If there is an occupant in the vehicle and the vehicle door is closed, the vehicle control device can also record (or lock and store) second information in the non-volatile storage medium of the vehicle. The second information can be used to indicate that the vehicle is in a first state, and the first state is a state where there is an occupant in the vehicle. When the vehicle door changes from closed to open, the second information is cleared from the non-volatile storage medium of the vehicle. Subsequently, when the vehicle door is closed, the above S210-S220 can be repeatedly executed to monitor whether there is an occupant in the vehicle.

[0102] In another example, if the vehicle control device implements S210 when it is in a dormant state, the vehicle control device may also wake up the vehicle control device when receiving an electrical signal from at least one component. The awakened vehicle control device may obtain the first information from the non-volatile storage medium of the vehicle, the first information being used to indicate that the vehicle is in a first state, the first state being a state in which there are passengers in the vehicle, and the first state being obtained according to a change in the physical state of at least one component of the vehicle.

[0103] As a result, the vehicle control device can be dormant and be awakened to control the vehicle when the physical state of any component of the vehicle changes. The vehicle control device does not need to work continuously, has no effect on the power consumption of the entire vehicle, and is more energy-efficient than continuously monitoring the status of the vehicle, which helps to increase the robustness of the entire vehicle system.

[0104] It should be understood that in the embodiment of the present application, the first information and the second information are merely information about the occupant's presence status locked and stored in the non-volatile storage medium of the vehicle under different circumstances, and the contents of the two may be the same.

[0105] S230: The vehicle control device determines that the door lock of the vehicle is in a locked state;

[0106] In the embodiment of the present application, the vehicle control device may determine that the door lock of the vehicle is in a locked state when receiving the vehicle locking control signal. The implementation details of S230 may vary depending on the different vehicle locking methods configured on the vehicle.

[0107] For example, if the vehicle uses a remote control locking method, when implementing S230, the vehicle control device can receive the locking control signal from the vehicle's smart key through a first wireless communication method. The vehicle control device can lock the vehicle doors according to the locking control signal and determine that the vehicle's door locks are in a locked state.

[0108] Or for example, if the vehicle adopts the intelligent locking mode, when implementing S230, the vehicle control device may receive the locking control signal from the user device through the second wireless communication mode. The vehicle control device may lock the vehicle door according to the locking control signal, and determine that the vehicle door lock is in the locked state.

[0109] For example, if the vehicle adopts an automatic locking mode, when implementing S230, the vehicle control device can receive the locking control signal from the keyless system PEPS of the vehicle. The vehicle control device can implement the control of locking the vehicle door according to the locking control signal, and at the same time determine that the vehicle door lock is in the locked state.

[0110] S240: The vehicle control device sends first warning information to the user equipment UE. Accordingly, the user equipment may receive the first warning information from the vehicle control device.

[0111] In the embodiment of the present application, the first warning information is used to indicate that the door lock is in a locked state and there is an occupant in the vehicle. The user can view the first warning information on the user device side and know that the door lock is in a locked state and there is an occupant in the vehicle, so that the occupant trapped in the vehicle can be rescued in time, thereby reducing accidents.

[0112] Optionally, if the door locks of the vehicle are in an unlocked state, the vehicle control device can also identify the specific scenario in which the occupants in the vehicle are located to determine whether the occupants in the vehicle have the ability to autonomously operate certain vehicle components, and send a second alarm message to the user device. The second alarm message is used to indicate the occupants in the vehicle's ability to manipulate at least one component of the vehicle, so as to enable the user to unlock the door or open the door, etc., thereby assisting the occupants in the vehicle to freely enter and exit the vehicle to reduce accidents.

[0113] It should be understood that Figure 2 The steps shown are merely examples of the steps that may be included in the vehicle method of the embodiment of the present application, and do not limit the execution order of the steps. In specific implementation, the execution order of the steps may be changed. Figure 2 The details of each step are described in detail.

[0135] Method (3):

[0136] When detecting whether there is an occupant in the front passenger seat, when the door is closed or opened, the method may include different logical links, such as Figure 6 As shown, the following steps may be included:

[0138] S602: The vehicle control device determines whether the front passenger door of the vehicle is closed. If so, the process proceeds to S603. If not, the process proceeds to S607.

[0139] S603: The vehicle control device determines whether there is an occupant in the front passenger seat according to whether the occupancy state of the seat occupancy sensor associated with the front passenger seat changes. If yes, that is, there is an occupant in the front passenger seat, then the process proceeds to S604.

[0145] Method (4):

[0146] Considering that in actual vehicle use, there are situations where the main driver's seat occupant gets off the vehicle from the front passenger door and the front passenger's seat occupant gets off the vehicle from the main driver's door, in order to more accurately determine the presence status of the occupants in the vehicle, the presence status of the front seat occupants can also be determined uniformly, such as Figure 7 As shown, the following steps may be included:

[0155] After determining the presence status of the front or rear occupants of the vehicle based on the above four methods, the vehicle control device can output the occupant presence status of the entire vehicle according to the presence status of the front and rear occupants, that is, if there are occupants in either the front or rear rows, it is considered that there are occupants in the vehicle. The vehicle control device can write the presence status of the occupants in the vehicle to the non-volatile storage medium of the vehicle so that it can promptly warn the user when necessary. Figure 8As shown, the method may include the following steps:
