The invention discloses a speed limiting control method for a new energy electric vehicle. The method comprises the steps that the vehicle running resistance moment of the vehicle at the highest required vehicle speed is calculated; the maximum value of the vehicle driving torque is determined according to the vehicle running resistance torque of the vehicle at the highest required vehicle speed; and speed limiting control is conducted on the vehicle according to the maximum value of the vehicle driving torque of the vehicle at the highest required vehicle speed. According to the speed limiting control method for the new energy electric vehicle, the driving resistance moment of the vehicle at the highest required vehicle speed is calculated according to the highest required vehicle speed of the vehicle in combination with the whole vehicle road resistance parameters, and the maximum value of the vehicle driving torque is determined accordingly, so that it is guaranteed that the driving torque is not larger than the vehicle driving resistance moment; therefore, the maximum speed of the vehicle does not exceed the speed limit requirement.
本发明公开了一种新能源电动车限速控制方法,包括:计算车辆在最高要求车速下的车辆行驶阻力矩;根据车辆在最高要求车速下的车辆行驶阻力矩确定车辆驱动扭矩的最大值;根据车辆在最高要求车速下的车辆驱动扭矩的最大值对车辆进行限速控制。本发明的新能源电动车限速控制方法,根据车辆的最高要求车速、结合整车道路阻力参数,计算出车辆在最高要求车速下的行驶阻力矩,据此来确定车辆驱动扭矩的最大值,以保证驱动扭矩不大于车辆行驶阻力矩,从而保证车辆最高车速不超过限速要求。
