A hill-start assist control method, device, readable storage medium, and vehicle

Abstract

The present application provides a hill-start assist control method, device, readable storage medium and vehicle, belonging to the field of vehicle technology. When the vehicle enters the hill-start assist driving mode, the traction required for the vehicle to start on the slope is calculated by obtaining the weight of the vehicle and the first slope of the slope on which the vehicle is located; then, based on the modified traction, the target throttle opening is determined, and the throttle opening of the vehicle engine is controlled to reach the target throttle opening; when the first current throttle opening triggered by the driver through the accelerator pedal is greater than the target throttle opening, the vehicle's handbrake is automatically released to complete the vehicle's hill-start, so that the hill-start operation no longer depends on the driver's experience, thereby improving the convenience and safety of vehicle driving. By pre-adjusting the engine's throttle opening to the target throttle opening, it can effectively reduce tire wear while avoiding the situation of slipping and stalling, and there is no need to change the hardware equipment, so the deployment cost is low.
