The invention discloses a speed setting control method during acceleration of an electric vehicle. The method is characterized by comprising the following steps: acquiring the highest speed limit of an electric vehicle, and acquiring a target speed from a rotating handle of the electric vehicle according to a first acceleration and a second acceleration set by the highest speed limit of the electric vehicle, setting a switching rotating speed for switching the first acceleration and the second acceleration according to the target speed; calculating the acceleration of a given speed and the given speed according to the first acceleration, and recording the working duration of the first acceleration; determining whether the real-time rotating speed is larger than the switching rotating speedor not, if so, recording the total working duration of the first acceleration, and calculating the acceleration of the given speed and the given speed through the second acceleration; judging whetherthe given speed is equal to the target speed or not, and if so, ending the acceleration process; by means of the method, smooth starting and powerful acceleration of the electric vehicle can be achieved.

    本发明公开了一种电动车加速时速度给定的控制方法,其特征在于,控制方法包括如下步骤:获取电动车的最高限速,根据电动车的最高限速设定的第一加加速度和第二加加速度从电动车转把获取目标速度,根据目标速度设置第一加加速度和第二加加速度切换的切换转速;以第一加加速度计算给定速度的加速度和给定速度,并记录第一加加速度的工作时长;判断实时转速是否大于切换转速,若是时,记录第一加加速度的工作总时长,以第二加加速度计算给定速度的加速度和给定速度;判断给定速度是否等于目标速度,若是时,加速过程结束;该方法能实现电动车平滑的起步和有力的加速。
