[0047] Figure 1 FIG2 shows a schematic diagram of the structure of a vehicle climbing control system provided by an embodiment of the present application. Figure 1 As shown, the vehicle climbing control system includes a power domain controller 11, an ignition switch 12, an engine 14 and a slope detector 13. The ignition switch 12, the engine 14 and the slope detector 13 are all electrically connected to the power domain controller 11.

[0048] Specifically, the slope detector 13 is used to detect the slope of the road and transmit the slope to the power domain controller 11. The slope detector 13 may be a sensor installed on the vehicle for detecting the slope of the road.

[0049] The ignition switch 12 has four positions: START, ON, ACC, and LOCK. The ignition switch 12 transmits gear information to the power domain controller 11 and can also switch gears based on control signals from the power domain controller 11.

[0050] The status of the engine 14 includes a start state and an off state. The engine 14 can transmit its own status information to the power domain controller 11 and can also switch between the start state and the off state according to the control signal of the power domain controller 11.

[0051] The power domain controller 11 is used to obtain the slope value, the gear position of the ignition switch 12, and the status of the engine 14. When the slope value exceeds a preset value and the status information indicates the engine is off, indicating that the vehicle has abnormally stalled while climbing a slope, the power domain controller 11 controls the ignition switch 12 to the on position to enable the normal operation of the vehicle's electronic systems. When the ignition switch 12 is in the on position, the power domain controller 11 activates the differential lock, increasing the vehicle's grip, reducing the risk of the vehicle rolling down the slope, and ensuring the safety of all occupants.

[0052] In one embodiment of the present application, the vehicle climbing control system further includes a four-wheel drive controller, which is electrically connected to the power domain controller 11. When the vehicle rolls down a slope, the power domain controller 11 sends a control signal to the four-wheel drive controller, which activates the steep slope descent function based on the control signal, controlling the vehicle to move slowly and smoothly to ensure the safety of people on board.

[0053] In one embodiment of the present application, the vehicle hill climbing control system further includes an instrument connected to the power domain controller 11. When the vehicle stalls while climbing a hill or rolls down the hill, the power domain controller 11 controls the instrument to display a braking prompt. After receiving the braking prompt via the instrument, the driver can promptly apply active braking (e.g., apply the brakes) to prevent the vehicle from rolling down the hill.

[0054] Figure 2 FIG2 shows a flow chart of a vehicle climbing control method provided by an embodiment of the present application. Figure 2 As shown, the vehicle climbing control method includes steps S201 to S203.

[0055] Step S201: Obtain the road slope value and engine status information.

[0056] Specifically, while the vehicle is driving, sensors on the vehicle can detect the road's slope. The engine can then monitor its own status and send it to the power domain controller. This allows the acquisition of both the road's slope and the engine's status.

[0057] Step S202: When the slope value is greater than a preset slope value and the engine status information indicates an abnormal shutdown state, the ignition switch is controlled to be switched to the on gear position.

[0058] Specifically, when the slope value is greater than a preset slope value, it indicates that the vehicle is climbing a slope. The preset slope value can be set based on actual conditions. For example, if the preset slope value is set to 45° and the vehicle is traveling on a road, if the detected road slope value is less than 45° and the engine abnormally stalls, the vehicle climbing control method will not be executed. If the detected road slope value is greater than 45° and the engine abnormally stalls, the ignition switch is controlled to the on position to power the vehicle's electronic systems and ensure that the vehicle can automatically brake.

[0059] Step S203: When the ignition switch is in the on position, activate the differential lock.

[0060] Specifically, when the ignition switch is in the on position, the electronic system on the vehicle is energized, activating the differential lock, increasing the vehicle's adhesion, reducing the risk of the vehicle sliding down a slope, and ensuring the safety of people on the vehicle.

[0061] In one embodiment of the present application, step S201 includes step S2011 and step S2012.

[0062] Step S2011, obtaining the slope value of the road.

[0063] Step S2012: When the slope value is greater than the preset slope value, obtain engine status information.

[0064] Specifically, when the slope value is greater than a preset value, it indicates that the vehicle is at risk of an abnormal engine shutdown, posing a safety hazard, and continuous monitoring of the engine status information is required. When the slope value is less than the preset value, it indicates that even if the vehicle's engine stalls, it will not pose a safety hazard, and monitoring of the engine status information is not required.

[0065] Figure 3 FIG2 shows a flow chart of a vehicle climbing control method provided by another embodiment of the present application. Figure 3 As shown, after step S203, the vehicle climbing control method further includes steps S204 and S205.

[0066] Step S204: determine whether the vehicle rolls down a slope.

[0067] Specifically, activating the differential lock increases the vehicle's grip and reduces the risk of the vehicle rolling down a slope. However, activating the differential lock does not guarantee that the vehicle will not roll down a slope. Therefore, when the differential lock is activated, it is necessary to determine whether the vehicle is rolling down a slope.

[0068] It should be noted that determining whether a vehicle has rolled down a slope can be done in a variety of ways. For example, an acceleration sensor installed on the vehicle can be used to detect vehicle motion information and analyze the vehicle motion information to determine whether the vehicle has rolled down a slope. Alternatively, an image capture device installed on the vehicle can be used to capture images of the vehicle's surroundings and analyze the images to determine whether the vehicle has rolled down a slope.

[0069] Step S205: activating the steep slope descent function when the vehicle rolls down the slope.

[0070] Specifically, the Hill Descent Control System is an automatic control system for downhill driving. Once activated, the vehicle automatically slows down and applies braking force to each wheel that exceeds a safe speed, ensuring a smooth descent. If the vehicle begins to roll down a slope, the Hill Descent Control System activates.

[0071] In one embodiment of the present application, when a vehicle rolls down a slope, a control instrument is controlled to display a braking prompt message. After receiving the braking prompt message through the instrument, the driver can actively brake (e.g., apply the brakes) in a timely manner to prevent the vehicle from rolling down the slope.

[0072] Figure 4 FIG2 shows a flow chart of a vehicle climbing control method provided by another embodiment of the present application. Figure 4 As shown, the vehicle climbing control method further includes step S401 and step S402.

[0073] Step S401: Obtaining the engine shutdown duration and the vehicle's active braking information.

[0074] Specifically, the engine off duration is the duration of time the engine is in the off state. The vehicle's active braking information is information indicating that the driver has applied the brakes. When the driver steps on the brake pedal, the active braking information indicates a braking state; when the driver does not step on the brake pedal, the active braking information indicates a non-braking state.

[0075] Step S402 : activating the hill descent function when the flameout duration is greater than a preset time and the active braking information indicates a non-braking state.

[0076] Specifically, if the vehicle's engine unexpectedly stalls while climbing a slope, a timer starts at the moment the engine stalls and records the stall duration. If the stall duration exceeds a preset time and the active braking information indicates a non-braking state, indicating a potential for the vehicle to roll down the slope, the hill descent control function is activated, ensuring a smooth descent and improving safety.

[0077] It should be noted that the preset time can be set according to actual needs. For example, the preset time can be set to 0.5 seconds, 1 second, 2 seconds, or 3 seconds. For example, if the preset time is set to 1 second, when the vehicle abnormally stalls while climbing a slope, the stall lasts for more than 1 second, and the active braking information indicates a non-braking state (the driver is not actively braking the vehicle), the hill descent control function is activated to allow the vehicle to descend smoothly, improving safety.

[0078] In one embodiment of the present application, step S402 further includes: acquiring accident data of the vehicle and storing the accident data.

[0079] Specifically, vehicle accident data includes information such as abnormal vehicle stalls, automatic activation of the differential lock, vehicle rolling down a slope, and automatic activation of the hill descent control function. If a vehicle stalls abnormally while climbing a slope and rolls down, the vehicle automatically records the accident data for later analysis.

[0080] In one embodiment of the present application, when the slope value is greater than a preset slope value and the engine status information is an abnormal shutdown state, the control instrument displays a braking prompt message.

[0081] Specifically, when the slope value is greater than the preset slope value and the engine status information is an abnormal shutdown state, the instrument displays a braking prompt message. After the driver receives the braking prompt message through the instrument, he can actively brake (such as stepping on the brakes) in time to prevent the vehicle from sliding down the slope.

[0082] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0096] The second information acquisition module is configured to acquire an engine-off duration and active brake information of the vehicle, wherein the engine-off duration is a duration during which the engine is in an engine-off state.

[0097] The second slow descent control module is configured to activate a steep slope slow descent function when the engine-off duration is greater than a preset time and the active brake information is in a non-braking state.
