The invention provides an electric vehicle running mode control method and system based on the driving intention of a driver and an electric vehicle. An accelerator pedal signal, a brake pedal signal and a motor working state of the vehicle in a preset period are obtained; the driver intention interpretation module judges the driving intention of a driver according to input conditions such as the vehicle speed, the opening degree of an accelerator pedal, the state of a brake switch and gear information, and the operation modes of the electric vehicle are divided into a parking mode, an idling mode, an acceleration mode and a sliding brake mode. According to the running condition of the electric vehicle, one of the four working states in which the vehicle runs is determined, then the motor output torque in the current mode is calculated, the potential of the motor can be exerted, the response is rapid, and the driving safety and reliability are improved.
本发明提供基于驾驶员驾驶意图的电动车运行模式控制方法、控制系统及电动车,获取汽车在预设周期内的加速踏板信号、制动踏板信号以及电机工作状态;驾驶员意图解释模块根据车速、加速踏板开度、制动开关状态、挡位信息等输入条件判断驾驶员的驾驶意图,并将电动车运行模式分为停车模式、怠速模式、加速模式、滑行制动模式四种,依据电动车运行条件确定车辆运行在四种工作状态下的哪一种,再分别计算当前模式下电机输出转矩,本发明可以发挥电机潜能,响应迅速,提高驾驶安全性和可靠性。
