[0002] With the rapid development of automotive technology, cars, as convenient means of transportation, have increasingly entered thousands of households. Among them, during the use of cars, if the driver fails to observe carefully due to distractions or other factors and starts the car when the passengers have not fully got on or off, that is, when the doors or trunk are not closed, it will pose a serious threat to the personal safety and property of the passengers and drivers. Therefore, in order to avoid such phenomena, it is particularly important to protect against starting the vehicle when the doors are not closed.

[0003] Currently, the systems in related technologies generally include a door switch acquisition circuit, a controller, an engine, and an ignition switch. The door switch acquisition circuit acquires the door opening state signal, and the controller controls the engine and the ignition switch according to the door opening state signal to achieve protection against starting when the doors are not closed. However, if the vehicle doors cannot be normally closed due to accidents or some special scenarios, but other systems are intact, the vehicle cannot be started either, and it is necessary to use towing resources, resulting in high labor costs and extremely easy to cause waste of social resources.

[0044] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] It is understandable that vehicle safety is directly related to people's life safety. If the driver drives the vehicle without closing the door, the people in the vehicle will be at risk of being thrown out, thus posing a safety hazard. Therefore, it is crucial to study the safety protection of starting the vehicle when the door is not closed.

[0047] At present, the system in the related technology generally includes a door switch acquisition circuit, a controller, an engine and an ignition switch. The door open state signal is collected by the door switch acquisition circuit, and the engine and ignition switch are controlled by the controller according to the door open state signal to achieve protection when the door is not closed. However, if the vehicle door cannot be closed normally due to an accident or some special scenarios, but other systems are intact, the vehicle cannot be started, and trailer resources must be used, resulting in high labor costs and easily causing waste of social resources.

[0048] Based on the above-mentioned defects, the present application provides a vehicle safety protection method, system, vehicle and storage medium. Compared with the prior art, this technical solution is provided with a first shielding mode and a second shielding mode. Therefore, when the user uses the vehicle to transport large items or certain special scenarios cause the door or trunk to be unable to close, it can automatically detect the shielding mode and shield the vehicle's safety lock signal through physical or software configuration to control the normal operation of the engine, ensure the normal start-up of the car, reduce labor costs, avoid wasting social resources, and the first shielding mode and the second shielding mode can be used as backup for each other, thereby improving system availability.

[0049] The vehicle safety protection method provided in the embodiment of the present application can be applied toFigure 1 The vehicle safety protection system shown in the figure.

[0050] Figure 1 It is a schematic diagram of the system structure of a vehicle safety protection system provided by an embodiment of the present application. As Figure 1 shown, the system includes: a door controller 101, a gear position switch 102, a gateway 103, an in-vehicle information device 104, and an engine controller 105. The in-vehicle information device 104 is connected to the door controller 101 and the engine controller 105 respectively through the gateway 103, and the door controller 101 is connected to the gear position switch 102.

[0051] The above-mentioned door controller 101 is used to obtain a safety locking signal and send the safety locking signal to the engine controller 105 through the gateway 103. The safety locking signal is generated according to the closed states of the detected door travel switches and the trunk travel switch; and it is also used to obtain a locking mode signal, send the locking mode signal to the in-vehicle information device 104 through the gateway 103, and is further used to control the door travel switches and the trunk travel switch. Among them, the above-mentioned door controller can detect the safety locking signal and the locking mode signal through GPIO (General Purpose Input and Output) pins.

[0052] Optionally, the above-mentioned door controller may include a microprocessor (MCU), memories (ROM, RAM), input / output interfaces (I / O), analog-to-digital converters (A / D), and large-scale integrated circuits such as shaping and driving.

[0053] As an implementable manner, the above-mentioned door controller may internally include a detection module, a processing module, and a communication module. The detection module is used to detect the safety locking signal and the locking mode signal; the communication module can be in a wireless or wired communication mode. The communication module is used to send the safety locking signal to the engine controller 105 through the gateway 103, and is also used to send the locking mode signal to the in-vehicle information device 104 through the gateway 103; the processing module is used to control the door travel switches and the trunk travel switch.

[0054] Please refer to Figure 2 and Figure 3As shown, the above gear position switch 102 can be a selection switch, which can be switched to two different gear position modes, namely the normal mode and the isolation mode. Among them, when the gear position switch is in the normal mode, the gear position switch is connected in series with each door travel switch and the trunk travel switch in the vehicle. Among them, the vehicle can include four door travel switches, namely the door 1 travel switch, the door 2 travel switch, the door 3 travel switch, and the door 4 travel switch. If all the door travel switches and the trunk travel switch in the vehicle are in the closed state, a safety lock signal is generated, and the safety lock signal is in the closed state. If any one of the door travel switches or the trunk travel switch in the vehicle is in the open state, a safety lock signal is generated, and the safety lock signal is in the open state.

[0055] When the gear position switch is switched to the isolation mode, the gear position switch is not connected in series with each door travel switch and the trunk travel switch in the vehicle, but is directly connected to the controller. For example, it can be connected to the controller through a wire. The controller can be an in-vehicle computer (Electronic Control Unit, ECU). When the gear position switch is switched to the isolation mode, a safety lock signal is generated immediately, and the safety lock signal does not affect the normal operation of the vehicle.

[0056] Among them, the above gear position switch further includes a gear position monitoring circuit, which is used to monitor the mode of the gear position switch. The ECU can be composed of a microcontroller (MCU), a memory (ROM, RAM), an input / output interface (I / O), an analog-to-digital converter (A / D), and large-scale integrated circuits such as shaping and driving.

[0057] The above gateway 103, also known as an inter-network connector and protocol connector, can achieve network interconnection above the network layer. It is a complex network interconnection device, only used for interconnection of two networks with different high-level protocols, and has various bus protocol conversion functions such as CAN, LIN, FLEXRAY, and ETHERNET. The gateway is used to establish network communication between the door controller, the in-vehicle information device, and the engine controller. Specifically, it is used to receive the safety lock signal sent by the door controller, send the safety lock signal to the engine controller, and is also used to receive the lock mode signal and send the lock mode signal to the in-vehicle information device.

[0058] The above in-vehicle information device 104 can be a display head unit (DHU) for driving information and entertainment. The DHU has a display interface, and the user can modify the function parameters of the safety lock signal soft shielding through this display interface. The display interface can include an interface pop-up window function to prompt the user with information.

[0059] When the above-mentioned engine controller 105 detects the shielding mode and determines that the vehicle complies with the safe driving rules, it shields the safety locking signal based on the shielding mode and controls the normal operation of the engine. Among them, the shielding mode includes a first shielding mode and a second shielding mode. The first shielding mode is generated when the gear switch is switched to the isolation mode; the second shielding mode is generated by the on-vehicle information device based on the configured safety locking signal soft shielding function parameters.

[0060] It should be noted that the above-mentioned engine controller may include a microprocessor (MCU), a memory (ROM, RAM), an input / output interface (I / O), an analog-to-digital converter (A / D), and large-scale integrated circuits such as shaping and driving.

[0061] Optionally, the above-mentioned on-vehicle information device 104 and the engine controller 105 can establish a communication connection with the door controller 101 through the gateway 103 in a wired or wireless manner, and the door controller 101 and the gear switch 102 can establish a communication connection in a wired or wireless manner.

[0062] For the convenience of understanding and explanation, the vehicle safety protection method, system, vehicle, and storage medium provided by the embodiments of the present application will be elaborated in detail below through Figures 4 to 8 The vehicle safety protection method, system, vehicle, and storage medium provided by the embodiments of the present invention will be elaborated in detail below.

[0063] Figure 4 As shown in the flowchart of a vehicle safety protection method provided by an embodiment of the present invention, this method can be executed by a vehicle safety protection system, and this system can be implemented as part or all of the vehicle safety protection system through software, hardware, or a combination of software and hardware. As Figure 4 shown, this method includes:

[0064] S101. The door controller obtains the safety locking signal and sends it to the engine controller. The safety locking signal is generated according to the closed states of the door travel switches and the trunk travel switch in the vehicle detected.

[0065] Specifically, the above-mentioned safety locking signal is used to indicate the closed states of the door travel switches and the trunk travel switch in the vehicle and is generated according to the closed states of the door travel switches and the trunk travel switch in the vehicle detected. The safety locking signal can include two states, one is the open state, and the other is the closed state. Among them, when all the door travel switches and the trunk travel switch in the vehicle are closed, the safety locking signal is in the closed state; when any one of the door travel switches or the trunk travel switch in the vehicle is not closed, the safety locking signal is in the open state.

[0066] The door controller can detect the safety locking signal and send the safety locking signal to the engine controller. Among them, it can send the safety locking signal to the engine controller within a preset period. The preset period is custom-set according to actual needs. For example, it can be 1000 ms, that is, the door controller sends the safety locking signal to the engine controller every 1000 ms.

[0067] S102. When the engine controller detects the shielding mode and determines that the vehicle complies with the safe driving rules, it shields the safety locking signal based on the shielding mode and controls the engine to work normally. The shielding mode includes a first shielding mode and a second shielding mode. The first shielding mode is generated when the gear switch switches to the isolation mode; the second shielding mode is generated by the in-vehicle information device based on the configured safety locking signal soft shielding function parameters.

[0068] It should be noted that the above shielding mode refers to shielding the safety locking signal, that is, regardless of the state of the safety locking signal, it does not affect the normal operation of the vehicle. That is to say, regardless of whether the door travel switches and the trunk travel switch are in the closed or open state, it does not affect the normal operation of the vehicle.

[0069] The above shielding mode can include a first shielding mode and a second shielding mode. The first shielding mode refers to shielding the safety locking signal physically; the second shielding mode refers to shielding the safety locking signal by software, and it is generated by the in-vehicle information device based on the configured safety locking signal soft shielding function parameters. Among them, the first shielding mode or the second shielding mode is caused by the safety locking signal not being closed. It may be because the vehicle is transporting large items, resulting in the trunk not being able to close, or because of other reasons such as an accident, when the locking signal cannot be closed and the isolation mode is triggered.

[0070] It should be noted that the first shielding mode is generated when the gear switch switches to the isolation mode. Among them, the gear switch can be a selection switch, and the selection switch can switch to two different gear modes, namely the normal mode and the isolation mode. Among them, please refer to Figure 5 As shown, when the gear switch is in the normal mode, the gear switch is connected in series with the door travel switches and the trunk travel switch in the vehicle. If all the door travel switches and the trunk travel switch in the vehicle are in the closed state, a safety locking signal is generated, and the safety locking signal is in the closed state. If any one of the door travel switches or the trunk travel switch in the vehicle is in the open state, a safety locking signal is generated, and the safety locking signal is in the open state.

[0071] When the gear position switch is switched to the isolation mode, the gear position switch is not connected in series with the door travel switches and the trunk travel switch in the vehicle, but is directly connected to the controller. For example, it can be directly connected to the controller through a wire. When the gear position switch is switched to the isolation mode, a safety lock signal is directly generated, and this safety lock signal does not affect the normal operation of the vehicle.

[0072] Specifically, the engine controller can detect the shielding mode. By detecting whether the vehicle is in the first shielding mode or the second shielding mode, when the first shielding mode or the second shielding mode is detected, the safety lock signal is shielded based on the shielding mode to control the normal operation of the engine.

[0073] As an optional implementation method, during the process of detecting whether the vehicle is in the first shielding mode, it can be through the gear position monitoring circuit to monitor the mode information of the gear position switch to detect the lock signal. When the lock signal indicates that the gear position switch is switched to the isolation mode, it is determined that the vehicle is currently in the first shielding mode; otherwise, it is determined that the vehicle is not currently in the first shielding mode. During the process of detecting whether the vehicle is in the second shielding mode, it can be to check whether a soft shielding signal can be received from the on-vehicle information device. This soft shielding signal is generated based on the configured safety lock signal soft shielding function parameters. When the soft shielding signal is received, it is determined that the vehicle is currently in the second shielding mode; otherwise, it is determined that the vehicle is not currently in the second shielding mode.

[0074] When the engine controller detects the shielding mode, that is, when it detects that the vehicle is in the first shielding mode or the second shielding mode, it is determined that the vehicle complies with the safe driving rules. When it is confirmed that the driving parameters of the vehicle are all normal, the safety lock signal is shielded based on the shielding mode to control the normal operation of the engine. For example, when it is confirmed that the vehicle is transporting large items, resulting in the trunk not being able to close, or due to other reasons such as an accident, the lock signal cannot be closed, but other system parameters are normal, then the safety lock signal is shielded to control the normal operation of the engine.

[0075] The present application provides a vehicle safety protection method, which obtains a safety lock signal through a door controller and sends it to an engine controller. The safety lock signal is generated after the gear switch detects the closed state of each door travel switch and the trunk travel switch, and when the engine controller detects the shielding mode and determines that the vehicle meets the safe driving rules, the safety lock signal is shielded based on the shielding mode to control the normal operation of the engine. The shielding mode includes a first shielding mode and a second shielding mode. The first shielding mode is generated when the gear switch is switched to the isolation mode; the second shielding mode is generated by the vehicle information device based on the configured safety lock signal soft shielding function parameters. Due to the provision of the first shielding mode and the second shielding mode, the technical solution can automatically detect the shielding mode when the user uses the vehicle to transport large items or some special scenes cause the door or trunk to be unable to close, and shield the vehicle's safety lock signal through physical or software configuration to control the normal operation of the engine, ensure the normal start of the car, reduce labor costs, and avoid wasting social resources. In addition, the first shielding mode and the second shielding mode can be used as backups for each other, which improves system availability.

[0076] In another embodiment of the present application, a method for monitoring whether a safety lock signal is shielded is also provided. Specifically, before shielding the safety lock signal based on the shielding mode, the engine controller can also generate a corresponding information prompt instruction based on the first shielding mode and the second shielding mode. The information prompt instruction is used to remind the user whether to continue to shield the safety lock signal, and then respond to the information prompt instruction to provide an information prompt for the first shielding mode or the second shielding mode.

[0077] Specifically, when a user physically isolates the vehicle and forgets to release the physical isolation mode for restoration, if the vehicle is used in the next driving cycle, that is, when the engine controller detects the first shielding mode after ignition, it can generate an information prompt instruction corresponding to the first shielding mode based on the first shielding mode. The information prompt instruction includes information prompt content corresponding to the first shielding mode, and in response to the information prompt instruction corresponding to the first shielding mode, an information prompt is provided for the first shielding mode.

[0078] Optionally, the information prompt instruction may be a voice announcement or a screen display of the DHU in the vehicle. The information prompt content may be, for example, "Hello, the current vehicle safety lock signal has not been formed and is in a physical isolation state. Do you want to continue using the first shielding mode?" to remind the user whether to continue isolating and shielding the safety lock signal.

[0079] It should be noted that one driving cycle of the above-mentioned vehicle refers to the entire process from when the vehicle is ignited to when the vehicle is turned off.

[0080] Furthermore, when the user uses software to isolate the system, that is, when the engine controller detects the second shielding mode after ignition, an information prompt instruction corresponding to the second shielding mode can be generated based on the second shielding mode. The information prompt instruction includes information prompt content corresponding to the second shielding mode, and in response to the information prompt instruction corresponding to the second shielding mode, an information prompt is provided for the second shielding mode.

[0081] Optionally, the information prompt instruction may be a voice broadcast or a screen display of the DHU in the vehicle. The information prompt content may be, for example, "Hello, the current vehicle safety lock signal has not been formed and is in a software isolation state. Do you want to continue using the second shielding mode?" to remind the user whether to continue shielding the safety lock signal.

[0082] In addition, the soft shielding function parameters of the safety lock signal can also be set to modify the shielding period of the safety lock signal in the first shielding mode to be valid within one driving cycle. When the vehicle is turned off, the software isolation fails, which can effectively prevent the owner from forgetting to restore the vehicle to normal mode, thereby improving the safety of vehicle use.

[0083] In this embodiment, whether the safety lock signal is blocked is prompted by information prompts, which can promptly remind the user to confirm whether to continue using the blocking mode, thereby further ensuring the safety of the user's use of the vehicle.

[0084] In another embodiment of the present application, Figure 6 This is a flow chart of the vehicle safety protection method provided in the embodiment of the present application. Figure 6 As shown, the method includes:

[0085] S201: When the engine controller does not detect the shielding mode, obtain a safety lock signal and vehicle speed information.

[0086] S202: Based on the safety lock signal and the vehicle speed information, determine whether the engine is controlled to operate normally.

[0087] It should be noted that the speed information of the above-mentioned vehicle may be obtained through a wheel speed sensor on the drive wheel axle, for example, it may be calculated through a preset formula based on the wheel diameter of the vehicle when it leaves the factory.

[0088] In the embodiments of this application, please refer to Figure 7As shown, during the process of the engine controller detecting the shielding mode after ignition, when the shielding mode is not detected, that is, when the first shielding mode is not detected through the gear monitoring circuit and the second shielding mode is not monitored, a safety lock signal can be obtained. By detecting the closed states of the travel switches of each vehicle door and the trunk travel switch, it is determined whether the safety lock signal is in the off state, that is, whether any one of the travel switches of each vehicle door and the trunk travel switch is in the open state. When it is determined that the safety lock signal is in the closed state, that is, when all the travel switches of each vehicle door and the trunk travel switch are closed, the engine output is allowed and the engine is controlled to work normally. When it is determined that the safety lock signal is in the off state, that is, when any one of the travel switches of each vehicle door and the trunk travel switch is open, it is determined whether the vehicle speed information is zero. When it is determined that the vehicle speed information is zero, the engine output is prohibited, that is, the engine is controlled to stop power output. When it is determined that the vehicle speed information is not zero, the engine output is allowed, that is, the engine is controlled to work normally.

[0089] Among them, during the process of determining whether the safety lock signal is in the off state, the door controller can send the safety lock signal to the engine controller at a preset period. When the engine controller does not obtain the safety lock signal within the first preset time, it is determined that the safety lock signal is in the off state. This preset period and the first preset time can be custom-set by the user according to actual needs. Among them, the preset period can be, for example, 1000 ms, and the first preset time can be, for example, 3000 ms. Exemplarily, the door controller can send the safety lock signal to the engine controller every 1000 ms. When the engine controller does not obtain the safety lock signal after more than 3000 ms, for safety reasons, it is determined that the safety lock signal is in the off state.

[0090] In this embodiment, when the shielding mode is not detected, the off state of the safety lock signal is determined by detecting whether each vehicle door travel switch and the trunk are closed, so as to judge whether the engine works normally based on the safety lock signal and the vehicle speed information. When the vehicle speed is zero and the safety lock signal is in the off state due to the fact that each vehicle door travel switch and the trunk are not closed, the engine output is prohibited, thus avoiding personal injury, death and property losses caused by the vehicle starting suddenly with the doors not closed.

[0091] In another embodiment of the present application, the in-vehicle information device obtains the safety lock signal and the lock mode signal from the door controller at a second preset time interval, and obtains the safety lock signal soft shielding function parameter from the engine controller. The lock mode signal is generated when the gear switch switches to the normal mode or the isolation mode. The in-vehicle information device performs information prompting based on the safety lock signal, the lock mode signal and the safety lock signal soft shielding function parameter.

[0092] It should be noted that the above engine controller has the function of configuring the soft shielding function parameters of the safety locking signal. The soft shielding function parameters of the safety locking signal are the configuration parameters required for software shielding of the safety locking signal. These configuration parameters can be displayed on the interface through the vehicle information device, and they can include parameters such as the time of the soft shielding function. For example, the option of "Enable Soft Shielding Function of Safety Locking Signal" can be displayed on the interface. The user can operate this option on the interface. For example, the user can select "Enable Soft Shielding Function of Safety Locking Signal" to enable it, or select "Enable Soft Shielding Function of Safety Locking Signal" to disable it, so that the vehicle information device shields the safety locking signal according to the configured soft shielding function parameters of the safety locking signal. Among them, the function parameters configured each time are valid within one driving cycle. When the vehicle shuts off, the configured function parameters will also automatically become invalid and be cleared.

[0093] Specifically, the above vehicle information device can obtain the safety locking signal and the locking mode signal from the door controller at a second preset time interval. The locking mode signal is generated when the gear shift switch switches to the normal mode or the isolation mode, and obtains the soft shielding function parameters of the safety locking signal from the engine controller at a second preset time interval.

[0094] As a realizable method, after the vehicle is ignited and started, if it is detected that the locking mode signal is in the isolation mode, that is, when it is detected that the vehicle is in the first shielding mode, a corresponding information prompt instruction is generated, and the safety locking signal is prompted through this information prompt instruction to prompt the user whether to resume the normal mode or continue to use the first shielding mode. Among them, the second preset time is customarily set by the user according to actual needs.

[0095] As another realizable method, after the vehicle is ignited and started, if it is detected that the soft shielding function parameters of the safety locking signal have been configured, that is, when it is detected that the vehicle is in the second shielding mode, a corresponding information prompt instruction is generated, and the safety locking signal is prompted through this information prompt instruction to prompt the user whether to resume the normal mode or continue to use the second shielding mode.

[0096] As yet another realizable method, after obtaining the safety locking signal and the configured soft shielding function parameters of the safety locking signal, when it is detected that the safety locking signal is in the off state and the "Enable Soft Shielding Function of Safety Locking Signal" is not enabled, when it is detected that the accelerator is depressed, a corresponding information prompt instruction can be generated, and the safety locking signal is prompted through this information prompt instruction to prompt the user that the safety locking signal is off, that is, there is an open in the door travel switch or the trunk travel switch in the vehicle.

[0097] Optionally, the information prompt instruction may be provided in the form of sound or screen display. When the information prompt is provided in the form of screen display, the prompt may be provided in the form of a pop-up window.

[0098] For example, when the vehicle information device is a DHU, the DHU may obtain the safety lock signal and lock mode signal from the door controller at a period of 1000ms, and at the same time obtain the configurable parameter "safety lock signal soft shielding function enable" from the engine controller at a period of 1000ms, and display it on the interface for prompting. After the vehicle is restarted, if the lock mode signal is detected to be "isolation mode", an audible and visual prompt may be issued, and displayed in a pop-up window on the DHU interface, prompting the owner to restore to normal mode or continue to use isolation mode; when the safety lock signal is disconnected and the "safety lock signal soft shielding function enable" is not enabled, if the accelerator is detected to be pressed, an audible and visual prompt may be issued, and displayed in a pop-up window on the DHU interface, prompting the owner that the safety lock signal is disconnected.

[0099] In this embodiment, when the vehicle is ignited, the user can be prompted with information to remind the user in time whether the shielding mode needs to be released to avoid risks.

[0100] In another embodiment of the present application, a method for detecting whether there is any getting on or off the vehicle is provided. The vehicle's speed information and safety lock signal can be obtained through a door controller. When it is determined that the vehicle's speed information is zero and the safety lock signal is in an off state, it is determined that there is any getting on or off the vehicle. When the door controller determines that the vehicle's speed information is not zero and the safety lock signal is in a closed state, it determines that there is no getting on or off the vehicle.

[0101] It should be noted that, when the speed information of the above-mentioned vehicle is zero, it means that the vehicle is at a standstill, and when the safety lock signal is in the disconnected state, it means that the door travel switches or the trunk switches in the vehicle are open, and there is user getting on or off the vehicle; when the speed information of the above-mentioned vehicle is not zero, it means that the vehicle is in a driving state, and when the safety lock signal is in the closed state, it means that the door travel switches or the trunk switches in the vehicle are closed, and there is no user getting on or off the vehicle.

[0102] In the embodiment of the present application, the vehicle's speed information and safety lock signal can be used to determine whether the vehicle has any boarding or exiting behavior, thereby preventing the user from driving when the vehicle has any boarding or exiting behavior, thereby ensuring the safety of the vehicle's driving.
