The invention discloses a vehicle crawling control method, equipment, and device, and a storage medium. The method comprises: when a target vehicle is in a crawling state, reading the current brake pressure from vehicle working condition information; increasing the clutch torque at different gradients according to the current brake pressure; when the clutch torque is increased to the preset torque, and adjusting the clutch torque through a preset PID adjusting algorithm according to the actual vehicle speed and the target vehicle speed, and controlling the vehicle to drive according to the adjusted clutch torque. Due to the fact that the clutch torque is adjusted through the PID algorithm by recognizing the vehicle speed and in combination with the actual vehicle speed and the target vehicle speed, vehicle driving is controlled, and the problems that in the prior art, crawling working conditions under different conditions cannot be considered, the user experience feeling is poor are solved. According to the method, the consistency of vehicle crawling under different working conditions is improved, it is ensured that the whole vehicle keeps good drivability, and the user experience feeling is improved.

    本发明公开了一种车辆蠕行控制方法、设备、存储介质及装置,本发明通过在目标车辆进入蠕行状态时,从车辆工况信息中读取当前制动压力,并根据当前制动压力控制离合器扭矩以不同的梯度增大,在离合器扭矩增大至预设扭矩时,根据实际车速和目标车速通过预设PID调节算法调节离合器扭矩,并根据调节后的离合器扭矩控制车辆行驶。由于本发明通过对车速的识别,结合实际车速和目标车速通过PID算法调节离合器扭矩,从而控制车辆行驶,本发明相对于现有技术中无法兼顾不同情况下的蠕行工况,从而导致用户体验感较差,本发明实现了提高不同工况下车辆蠕行的一致性,确保整车保持较好的驾驶性,提升用户体验感。
