The invention provides a vehicle braking method and device, equipment, a storage medium and a product. The method comprises the steps that when it is determined that a vehicle is in a moving state according to the power state and the wheel speed of the vehicle, whether the vehicle is in a braking state or not is determined according to accelerator pedal data, braking stroke data and braking pressure data, an electric power assisting state position is obtained based on the braking state, and whether electric power assisting fails or not is determined; the expected deceleration and the actual deceleration of the vehicle are respectively determined when the vehicle fails, so that the auxiliary deceleration compensated for the vehicle is determined based on the expected deceleration and the actual deceleration, the anti-dragging deceleration is determined according to the battery temperature, the battery electric quantity and the vehicle speed, deceleration is executed through the electric drive controller when the auxiliary deceleration is not larger than the anti-dragging deceleration, and otherwise, deceleration is executed through the electric drive controller. A supplemental deceleration that the auxiliary deceleration exceeds the back-drag deceleration is determined, and deceleration is performed by the brake based on the supplemental deceleration. According to the method, the reliability and accuracy of vehicle braking are improved, and the vehicle driving safety is improved.

    本申请提供一种车辆制动方法、装置、设备、存储介质以及产品。该方法包括:通过车辆的动力状态和轮速确定车辆为运动状态时,根据油门踏板数据、制动行程数据和制动压力数据确定车辆是否为制动状态,基于制动状态获取电动助力状态位并确定电动助力是否失效,在失效时分别确定车辆的预期减速度和实际减速度,从而基于预期减速度和实际减速度确定向车辆补偿的辅助减速度,根据电池温度、电池电量和车速确定反拖减速度,在辅助减速度不大于反拖减速度时通过电驱控制器执行减速,否则,确定辅助减速度超出反拖减速度的补充减速度,并通过制动器基于补充减速度执行减速。本申请的方法,增加了车辆制动的可靠性和精准性,提高了车辆驾驶安全性。
