The invention discloses an intelligent acceleration control method for an electric vehicle, which comprises the following steps: judging whether the pedal opening degree of an accelerator pedal is within an effective range of intelligent acceleration or not, and if so, acquiring force information of stepping on the accelerator pedal according to a preset sampling period; motor torque corresponding to the acceleration required by the driver is obtained according to the force information and the current vehicle speed; and the motor driving controller adjusts and outputs the motor torque corresponding to the acceleration required by the driver by setting a first constraint condition based on the driving anti-skid control system. According to the intelligent acceleration control method for the electric automobile, the output value of the motor driving controller is calculated only by combining the pedal stepping force of a driver and the current automobile speed, and the motor driving controller can drive the motor to operate according to different output modes of the motor under the conditions of different opening degrees and force of the accelerator pedal and different automobile speeds. Real-time foot following in the acceleration process is achieved, acceleration is conducted according to the control intention of the driver, and the comfort of the driver is improved.
本发明公开了一种电动汽车智能加速控制方法,包括:判断加速踏板的踏板开度是否处于智能加速的有效范围内,若是,则按照预设采样周期获取踩下加速踏板的力度信息;根据力度信息和当前车速获取驾驶人员需求加速度对应的电机扭矩;电机驱动控制器通过基于驱动防滑控制系统设置第一约束条件对驾驶人员需求加速度对应的电机扭矩进行调整输出。本实施例提供的电动汽车智能加速控制方法,只需结合驾驶人踩下踏板的力度和当前的车速,计算出电机驱动控制器的输出值,在加速踏板不同开度和力度以及不同车速下,电机驱动控制器针对电机的输出模式不同,实现加速过程实时跟脚,根据驾驶人的操控意图进行加速,提高了驾驶人的舒适性。
