The invention provides a brake pedal opening degree calculation method and device and an electric vehicle. The method comprises the following steps: acquiring a first stroke signal of a first circuit and a second stroke signal of a second circuit of a brake pedal; generating an opening signal of the brake pedal according to the first stroke signal and the second stroke signal; and sending the opening signal of the brake pedal to a motor controller. According to the method for calculating the opening degree of the brake pedal, the vehicle controller simulates and generates the electric signal of the stroke opening degree of the brake pedal through the collected two paths of electronic electric signals, and the opening degree of the brake pedal is effectively calculated. According to the brake pedal opening degree calculation method, the motor controller can conduct energy recovery matched with the specified pedal opening degree according to the electric signal of the brake pedal stroke opening degree, and it is ensured that a driver accurately recognizes the actual size of the brake pedal stepping opening degree of the whole vehicle.

    本发明提供了一种制动踏板开度计算方法、装置及电动汽车。该方法包括,获取制动踏板的第一电路的第一行程信号和第二电路的第二行程信号;根据所述第一行程信号和所述第二行程信号,生成所述制动踏板的开度信号;将所述制动踏板的开度信号发送给电机控制器。本发明实施例的制动踏板开度计算方法,车辆控制器通过采集到的电子式两路电信号,模拟生成制动踏板行程开度的电信号,有效的对制动踏板开度进行计算。本发明实施例的制动踏板开度计算方法,可以使电机控制器根据制动踏板行程开度的电信号进行与指定踏板开度相匹配的能量回收,确保了整车对驾驶员对制动踏板踩踏开度的实际大小的准确识别。
