The invention discloses a motor signal processing system of an electric vehicle. The motor signal processing system comprises a sensing module, a communication module and a main control module, the sensing module and the communication module are both connected with the main control module; the sensing module is used for collecting an initial motor signal; the communication module is used for transmitting an initial motor signal to the main control module; the master control module is used for collecting pulse signals of the initial motor signals at preset intervals according to a built-in timer, counting single sudden change signals of the pulse signals, and determining the signal period of the initial motor signals according to the single sudden change signals. According to the method, the situation that the motor signal cannot be accurately obtained due to interference can be effectively avoided, the signal period of the initial motor signal can be determined only by counting the single abrupt change signal, the signal period of the motor signal can be accurately determined, and the accuracy and reliability of processing the motor signal can be effectively improved.
本发明公开了一种电动车的电机信号处理系统,包括:传感模块、通信模块和主控模块;传感模块和通信模块均与主控模块连接;传感模块用于采集初始电机信号;通信模块用于将初始电机信号传输至主控模块;主控模块用于根据内置的定时器,以预设间隔采集初始电机信号的脉冲信号,统计脉冲信号的单次突变信号,根据单次突变信号确定初始电机信号的信号周期。本发明能够有效避免因受到干扰而无法准确获取电机信号的情况发生,且仅统计单次突变信号以确定初始电机信号的信号周期,能够准确确定电机信号的信号周期,能够有效提高处理电机信号的准确性和可靠性。
