The invention discloses an idle speed control method and a system for an electric vehicle. The method comprises the steps that a vehicle control unit judges whether the vehicle is in a starting stateor not; if the vehicle is in the starting state, the whole vehicle controller receives a braking torque request state signal sent by the electronic hydraulic braking controller, a gear state signal sent by the gear controller, a vehicle speed signal and an automatic parking state signal sent by the electronic stability control system, and an electronic parking state signal sent by the electronic parking controller; the vehicle control unit judges whether the received braking torque request state signal, the gear state signal, the vehicle speed signal, the automatic parking state signal and theelectronic parking state signal are respectively preset values; and if yes, the vehicle control unit sends an idling torque request signal to the motor controller, and the motor controller controls to execute idling torque output. The idle speed working condition can be increased in the electric automobile.

    本发明公开了一种电动汽车怠速控制方法及系统,该方法包括:整车控制器判断车辆是否处于启动状态;若车辆处于启动状态,则整车控制器分别接收电子液压制动控制器发送的制动扭矩请求状态信号、档位控制器发送的档位状态信号、电子稳定控制系统发送的车速信号和自动驻车状态信号、电子驻车控制器发送的电子驻车状态信号;整车控制器分别判断接收到的制动扭矩请求状态信号、档位状态信号、车速信号和自动驻车状态信号、电子驻车状态信号是否均为各自的预设值;若是,则整车控制器发送怠速扭矩请求信号至电机控制器,并由电机控制器控制执行怠速扭矩输出。本发明能够在电动汽车中增加怠速工况。
