The invention discloses a new energy automobile speed limiting control method and device and a new energy automobile. The method comprises the steps that a vehicle control unit obtains a vehicle speed signal from an anti-lock braking system; the vehicle control unit obtains a motor rotating speed signal from the motor controller; the vehicle control unit obtains a gradient signal from the gradient sensor; the vehicle control unit calculates and processes the received signals, decides the speed of the whole vehicle, and sends the speed of the whole vehicle and the fault information of the speed to the combination instrument for vehicle speed display and fault reminding; and the vehicle control unit judges whether the current vehicle speed exceeds a set threshold value or not, and if yes, the vehicle control unit controls the torque of the motor. According to the invention, an existing vehicle speed judgment strategy is optimized, a more intelligent checking method is realized, and the actual vehicle speed is calculated truly, effectively and accurately.

    本发明公开了一种新能源汽车限速控制方法、装置及新能源汽车,所述方法包括:整车控制器从防抱死制动系统获取车速信号;整车控制器从电机控制器获取电机转速信号;整车控制器从坡度传感器获取坡度信号;整车控制器对接收到的信号进行计算处理,决策出整车车速,把整车车速和车速的故障信息发送给组合仪表,进行车速显示和故障提醒;整车控制器判断当前车速是否超过设定阈值,如果是,则整车控制器对电机的转矩进行控制。本发明优化现有车速判断策略,实现更智能的校核方法,真实、有效、准确的计算出车辆实际速度。
