[0068] In order to facilitate understanding and explanation of the technical solutions provided by the embodiments of the present application, the background technology of the present application will be described below.

[0069] Some vehicles are equipped with a parking gear button and an electronic parking brake button. These buttons are used to assist with parking. If the parking gear button or the electronic parking brake button malfunctions, or in unusual circumstances, such as those encountered during vehicle testing, the driver may have difficulty controlling the vehicle using these buttons.

[0070] Based on this, the embodiments of the present application provide a vehicle control method, device, equipment and medium based on an electronic shift module, which is applied to an electronic shift module including a parking gear button and an electronic parking brake system button, wherein the parking gear button and the electronic parking brake system button are triggered synchronously. The vehicle's operating data is obtained, and the operating mode of the electronic shift module is determined based on the vehicle's operating data. For a fault mode or a special scenario mode, in response to the pressing operation of the parking gear button, the vehicle can be adjusted according to the preset adjustment method corresponding to the operating mode. In this way, the vehicle can be controlled using the preset adjustment method in the fault mode or the special scenario mode, which can meet the driver's driving needs.

[0071] In order to facilitate understanding of the technical solution provided by the embodiment of the present application, the vehicle control method based on the electronic shift module provided by the embodiment of the present application is described below with reference to the accompanying drawings.

[0072] It should be noted that the vehicle control method based on the electronic shift module provided in the embodiment of the present application can be applied to the electronic shift module on the vehicle. The electronic shift module includes a parking gear button and an electronic parking brake (EPB) system button. The P gear button is used to switch to the parking gear. The EPB system button is used to turn on or off the EPB system. The P gear button is set on the vehicle's dashboard or on the vehicle's steering column. Figure 1 As shown in FIG, this figure is a schematic diagram of a P gear button provided in an embodiment of the present application. The P gear button is set on the steering column of the vehicle.

[0073] The P button is triggered synchronously with the EPB system button. That is to say, when both the P button and the EPB system button are working normally, the driver pressing the P button will trigger the EPB system button at the same time.

[0074] The embodiment of the present application does not limit the connection method between the P gear button and the EPB system button. In a possible implementation, the P gear button can be mechanically connected to the EPB button through a transmission rod. Figure 2 As shown in the figure, this figure is a schematic diagram of the structure of an electronic shift module provided by an embodiment of the present application. The P gear button and the EPB system button are connected by a transmission rod. After the driver presses the P gear button, the EPB system button will be triggered at the same time. In another possible implementation, the P gear button and the EPB system button can be connected electrically, that is, after the driver presses the P gear button, the circuit operation of the P gear button can be triggered, and a signal can be sent to the circuit of the EPB system button to trigger the circuit operation of the EPB system button.

[0075] The following describes a vehicle control method based on an electronic shift module provided in an embodiment of the present application. Figure 3 As shown in FIG, this figure is a flow chart of a vehicle control method based on an electronic shift module provided in an embodiment of the present application. Figure 3 As shown, the method includes S301-S303.

[0076] S301: Acquire vehicle operation data.

[0077] The vehicle's operating data is used to determine the operating mode of the electronic shift module. The specific data types included in the vehicle's operating data are determined based on the operating mode of the electronic shift module.

[0078] In one possible implementation, detection data from the P shift button and the EPB system button included in the vehicle's electronic shift module are obtained as vehicle operating data. Based on these detection data, it is possible to determine whether the electronic shift module is in a fault mode. In another possible implementation, vehicle gear position, speed data, engine status data, and brake pedal position are obtained as operating data to determine whether the electronic shift module is in a special scenario mode.

[0079] S302: Determine the operating mode of the electronic shift module according to the operating data.

[0080] The operating modes of the electronic shift module include one or more of a fault mode and a special scenario mode. The fault mode is when the electronic shift module is faulty. The special scenario mode is when the electronic shift module operates under specific driving requirements.

[0081] Specifically, if the acquired operating data can satisfy the conditions for determining the mode, the operating mode corresponding to the electronic shift module is determined.

[0082] S303: In response to the pressing operation on the parking gear button, adjust the vehicle according to a preset adjustment method.

[0083] After determining the operating mode of the electronic shift module, in response to a press operation on the P gear button, the vehicle is adjusted according to a preset adjustment method corresponding to the operating mode, wherein the preset adjustment method is an adjustment method pre-set by the electronic shift module in the operating mode and corresponding to the press operation.

[0084] Based on the above S301-S303, it can be seen that by determining the operating mode of the electronic shift module and responding to the pressing of the P gear button, the vehicle is adjusted using a preset adjustment method. This allows the vehicle to be adjusted in the event of a fault or special scenario without changing the existing hardware structure, meeting the driver's driving needs.

[0085] The following embodiments of the present application provide specific implementations of four working modes.

[0086] The first one: the working mode is the hub mode.

[0087] The acquired vehicle operating data includes engine status data, vehicle gear position, brake pedal position, and wheel speed. The engine status data is used to determine whether the engine is running or off. The vehicle gear position is used to determine the vehicle's current gear position. The brake pedal position is the current position of the vehicle's brake pedal. The wheel speed includes the speed of the vehicle's front and rear wheels.

[0088] Determining an operating mode of the electronic shift module according to the operating data includes:

[0089] If the engine status data indicates that the engine is in an off state, the vehicle gear is in neutral, the brake pedal opening is zero, and the wheel speed meets the speed condition, it is determined that the electronic shift module is in a rotary hub mode.

[0090] In the rotating hub mode, the request for pressing the P gear button is blocked, and only the triggering of the EPB system button is responded to.

[0091] The rotating hub mode is used for testing a vehicle's EPB system. This mode is suitable for EPB system testing scenarios. For example, when testing the EPB system's clamping force before a vehicle rolls off the production line, rotating hub mode can be used. Another example is when a vehicle undergoes annual EPB system inspection.

[0092] The speed condition is that the vehicle's front wheel speed is less than a first threshold, the vehicle's rear wheel speed is greater than or equal to a second threshold and less than or equal to a third threshold, and the coaxial wheel speed difference is less than a fourth threshold. The embodiments of the present application do not limit the specific values ​​of the first, second, and third thresholds included in the speed condition. The first, second, and third thresholds may be set as needed. As an example, the first threshold is 1 kilometer per hour. The second threshold is 1.8 kilometers per hour. The third threshold is 18 kilometers per hour. The fourth threshold is 1.8 kilometers per hour.

[0093] In response to a pressing operation on the parking gear button, adjusting the vehicle according to a preset adjustment method, including:

[0094] In rotating hub mode, the P gear button is blocked from being triggered. In response to a press of the Park gear button, if the P gear button is pressed, the electronic parking brake system is activated. If the P gear button is released, the electronic parking brake system is deactivated.

[0095] The second type: the working mode is the parking gear button failure mode.

[0096] In a possible implementation, in the parking gear button failure mode, the EPB system button can be used to control the P gear.

[0097] The operation data includes detection data of the parking gear button. Specifically, the detection data of the parking gear button includes an analog signal triggered by the P gear button.

[0098] Determining the operating mode of the electronic shift module according to the operating data includes:

[0099] If the detection data of the parking gear button indicates that the parking gear button operates abnormally, it is determined that the electronic shift module is in a parking gear button failure mode.

[0100] The Park Shift button failure mode is a mode in which the P Shift button is faulty. An operational abnormality of the Park Shift button includes damage to or an abnormality in the P Shift button. As an example, the Park Shift button detection data includes an analog signal triggered by the P Shift button. If the detection data indicates that the analog signal triggered by the P Shift button cannot be detected, the P Shift button is determined to be damaged. If the detection data indicates that the analog signal triggered by the P Shift button is abnormal within a preset time, the P Shift button is determined to be abnormal. The preset time is, for example, 30 seconds.

[0101] In response to a pressing operation on the parking gear button, adjusting the vehicle according to a preset adjustment method, including:

[0102] In response to the pressing operation of the parking gear button, if the electronic parking brake system button is in a pressed state, the gear position of the vehicle is switched to the parking gear and the electronic parking brake system is turned on; if the electronic parking brake system button is in a pop-up state, the gear position of the vehicle is switched from the parking gear to the non-parking gear, and the electronic parking brake system is turned off.

[0103] In the Park shift button fault mode, the Park shift and EPB system are controlled based on the status of the EPB system button. If the Park shift button remains pressed, the vehicle's shift position is changed to Park and the EPB system is activated. If the Park shift button remains released after being pressed, the vehicle's shift position is changed from Park to a non-P shift position and the EPB system is deactivated.

[0104] In another possible implementation, in the parking gear button failure mode, the signal triggered by the parking gear button can be shielded first to avoid the problem of being unable to switch gears normally after the parking gear button fails.

[0105] The operation data includes the detection data of the parking gear button. Specifically, the detection data of the parking gear button includes the analog signal triggered by the P gear button.

[0106] Determining the operating mode of the electronic shift module according to the operating data includes:

[0107] If the detection data of the parking gear button indicates that the parking gear button operates abnormally, it is determined that the electronic shift module is in a parking gear button failure mode.

[0108] The method further comprises:

[0109] Shield the signal triggered by the parking gear button.

[0110] After determining that the Park shift button is faulty, the signal triggered by the Park shift button is blocked. For example, the signal that switches to P gear when the Park shift button is pressed is blocked. This allows automatic control of the vehicle's gear position when the Park shift button is faulty, avoiding the situation where the gear position cannot be adjusted.

[0111] The third type: The working mode is the electronic parking brake system button failure mode.

[0112] The operating data includes detection data of the electronic parking brake system and detection data of the parking gear button. Specifically, the detection data of the electronic parking brake system is data indicating whether the EPB system is operating. The detection data of the parking gear button is status data of the parking gear button, indicating whether the parking gear button is pressed or released.

[0113] Determining an operating mode of the electronic shift module according to the operating data includes:

[0114] If the detection data of the parking gear button indicates that the parking gear button is in a pressed state, and the detection data of the electronic parking brake system indicates that the electronic parking brake system is not turned on, it is determined that the electronic shift module is in an electronic parking brake system button failure mode.

[0115] The EPB system button failure mode is a mode in which the EPB system button fails. Specifically, if the Park button detection data indicates that the P shift button is pressed, but the electronic parking brake system detection data indicates that the EPB system is not engaged, this indicates that the EPB system button is faulty.

[0116] In response to a pressing operation on the parking gear button, adjusting the vehicle according to a preset adjustment method, including:

[0117] In response to the pressing operation of the parking gear button, if the parking gear button is in a pressed state, the gear position of the vehicle is switched to the parking gear and the electronic parking brake system is turned on; if the parking gear button is in a pop-up state, the gear position of the vehicle is switched from the parking gear to the non-parking gear, and the electronic parking brake system is turned off.

[0118] In the EPB system button failure mode, the P gear and EPB system are adjusted according to the status of the P gear button.

[0119] In response to a press operation on the parking gear button, if the P gear button is in a pressed state after the press operation, the vehicle's current gear is switched to P gear and the EPB system is activated. If the P gear button is in a pop-up state after the press operation, the vehicle's current gear is switched from P gear to another gear and the EPB system is deactivated.

[0120] The fourth type: The working mode is the vehicle transmission control module failure mode.

[0121] It should be noted that, in one possible implementation, the vehicle is equipped with a vehicle transmission control module. The vehicle transmission control module is used to automatically switch the gear of the vehicle. The electronic shift module can generate a gear switching request based on the state of the P gear button. If the P gear button is in a pressed state, a gear switching request to switch to the P gear is generated. If the P gear button is in a pop-up state, a gear switching request to switch to a non-P gear is generated. The electronic shift module sends a gear switching request to the vehicle transmission control module. The vehicle transmission control module adjusts the gear of the vehicle according to the gear switching request.

[0122] The operating data includes detection data of the vehicle transmission control module and detection data of the electronic parking brake system button.

[0123] The detection data of the vehicle transmission control module is used to indicate whether the vehicle transmission control module is operating normally. The detection data of the vehicle transmission control module is, for example, the operating data of the vehicle transmission control module. The detection data of the electronic parking brake system button is used to indicate whether the EPB system button is operating normally. In one possible implementation, the detection data of the electronic parking brake system button may be the operating data of the EPB system button. In another possible implementation, the detection data of the electronic parking brake system button may include data on whether the EPB system is operating and status data of the P gear button. A fault in the EPB system button is determined based on the pressed state of the P gear button and the fact that the EPB system is not operating.

[0124] Determining the operating mode of the electronic shift module according to the operating data includes:

[0125] If the detection data of the vehicle transmission control module indicates that the vehicle transmission control module is operating abnormally, and the detection data of the electronic parking brake system button indicates that the electronic parking brake system button is operating abnormally, it is determined that the electronic shift module is in the vehicle transmission control module failure mode.

[0126] The vehicle's transmission control module failure mode refers to the mode in which the vehicle's transmission control module fails. When the vehicle's transmission control module fails, it is uncertain whether the vehicle's gear adjustment can be performed. To ensure vehicle safety, it is also necessary to trigger the EPB system to operate normally and maintain vehicle control when a failure in the EPB system button is determined.

[0127] In response to a pressing operation on the parking gear button, adjusting the vehicle according to a preset adjustment method, including:

[0128] In response to the pressing operation of the parking gear button, if the parking gear button is in a pressed state, a gear switching request for switching to the parking gear is generated, the gear switching request for switching to the parking gear is sent to the vehicle transmission control module, and the electronic parking brake system is turned on; if the parking gear button is in a pop-up state, a gear switching request for switching to a non-parking gear is generated, the gear switching request for the non-parking gear is sent to the vehicle transmission control module, and the electronic parking brake system is turned off.

[0129] In the vehicle transmission control module's fault mode, a corresponding request is sent to the vehicle transmission control module based on the status of the P gear button, and the EPB system is adjusted. In response to a press of the Park gear button, if the Park gear button remains in the pressed state after the press, a gear shift request is generated for switching to Park gear, which is sent to the vehicle transmission control module, activating the electronic parking brake system. If the Park gear button remains in the released state after the press, a gear shift request is generated for switching to a non-Park gear, which is sent to the vehicle transmission control module, deactivating the electronic parking brake system. By sending a gear shift request to the vehicle transmission control module, gear adjustment can be attempted using the vehicle transmission control module. By controlling the EPB system, the vehicle's parking function is ensured, improving vehicle safety.

[0130] Based on the vehicle control method based on the electronic shift module provided in the above method embodiment, the embodiment of the present application also provides a vehicle control device based on the electronic shift module. The vehicle control device based on the electronic shift module will be described below in conjunction with the accompanying drawings.
