The invention provides an electric vehicle torque distribution method and system, a computer and a readable storage medium, and the method comprises the steps: obtaining a high-definition map containing a current vehicle driving environment through a collection device, and obtaining the vehicle information and road information of a vehicle according to the high-definition map; calculating the following distance between the vehicle and the front vehicle according to the vehicle information and the road information, and inputting the following distance and the speed of the vehicle into a ring reinforcement learning model to obtain a target acceleration; calculating the total required torque of the vehicle according to the target acceleration and the actual speed of the vehicle; and obtaining an off-line torque distribution coefficient of the vehicle, and calculating actual demand torque corresponding to the four wheels of the vehicle according to the total demand torque and the off-line torque distribution coefficient. By means of the mode, on the premise that the dynamic property and the braking stability of the vehicle are guaranteed, energy-saving comprehensive torque distribution is conducted, and the endurance mileage of the electric vehicle is greatly increased.
本发明提供了一种电动汽车力矩分配方法、系统、计算机及可读存储介质,该方法包括通过采集设备获取包含有当前车辆行驶环境的高清地图,并根据高清地图获取到车辆的车辆信息以及道路信息;根据车辆信息以及道路信息计算出车辆与前车之间的跟车距离,并将跟车距离以及车辆的车速输入至环强化学习模型中,以获取到目标加速度;根据目标加速度以及车辆的实际车速计算出车辆的总需求力矩;获取车辆的离线力矩分配系数,并根据总需求力矩以及离线力矩分配系数计算出车辆的四个车轮分别对应的实际需求力矩。通过上述方式能够在保证车辆动力性和制动稳定性的前提下,进行节能的综合力矩分配,大幅提高了电动汽车的续航里程。
