The invention discloses an acceleration control method and device for an electric automobile, and the method comprises the steps: determining a preset reference driving torque and a preset driving acceleration according to the current rotating speed of a motor if an accelerator signal is received during the running of the automobile, and taking the preset driving acceleration as the target acceleration of the whole automobile; wherein under different motor rotating speed-preset reference driving torque combinations, although loads and road conditions are different, the driving feelings are the same; calculating the actual acceleration of the current vehicle as an acceleration feedback value; determining a whole vehicle driving torque compensation value according to the whole vehicle target acceleration and the acceleration feedback value; determining a motor target driving torque according to the whole vehicle driving torque compensation value and a preset reference driving torque; and determining the actual electric execution torque of the motor according to the motor target driving torque. The electric quantity of the battery is saved to the maximum extent under the condition that the driving feelings of a driver are consistent, and the purpose of increasing the driving range can be achieved to a certain extent.
本申请公开了一种电动汽车的加速控制方法及装置,方法包括:在车辆行驶时,若接收到油门信号,则依据当前的电机转速确定预设基准驱动扭矩和预设驱动加速度,将预设驱动加速度作为整车目标加速度;其中,不同的电机转速‑预设基准驱动扭矩组合下,尽管载重和路况不同,驾驶感受是相同的;计算当前车辆的实际加速度,作为加速度反馈值;依据整车目标加速度和加速度反馈值确定整车驱动扭矩补偿值;依据整车驱动扭矩补偿值和预设基准驱动扭矩确定电机目标驱动扭矩;依据电机目标驱动扭矩确定电机的实际电动执行扭矩。本申请在确保驾驶员驾驶感受一致的情况下最大限度节约电池电量,一定程度上能达到增加续驶里程的目的。
