The invention provides a signal processing device for an electric vehicle and the electric vehicle. The electric vehicle comprises a motor, a motor controller used for controlling the motor and an anti-lock device, the motor carries a detection sensor used for detecting rotation information of the motor, and the detection sensor outputs a signal containing the rotation information to the motor controller; the signal processing device comprises a signal processor, and the signal processor is used for being connected with the detection sensor and the anti-lock device and processing signals output by the detection sensor into anti-lock control signals available for the anti-lock device. According to the device, anti-lock control can be carried out by using the motor rotation related signals output by the detection sensor carried by the motor, so that a wheel speed sensor and related processes thereof are omitted, the cost is reduced, and the complexity of installation and maintenance is reduced.

    本申请提供一种用于电动车的信号处理装置以及电动车。电动车包括电机、用于控制电机的电机控制器、以及防抱死装置,电机携带有用于检测电机的转动信息的检测传感器,检测传感器向电机控制器输出包含转动信息的信号;信号处理装置包括信号处理器,信号处理器用于分别与检测传感器和防抱死装置连接,并将检测传感器输出的信号处理为防抱死装置可用的防抱死控制信号。该装置可以利用电机携带的检测传感器输出的电机转动相关的信号进行防抱死控制,从而省略轮速传感器及其相关工艺,以降低成本,减少安装和维护的复杂度。
