The invention provides a system for driving a vehicle by using a handle signal, and the system comprises a handle which is used for transmitting a handle position signal, and the handle position signal comprises a push rod signal or a pull rod signal; the median value generating circuit is used for generating a median value signal; the enabling key is located on a circuit between the power supply and the handle, and when the enabling key is pressed down, the power supply provides voltage for the handle; the relay and the enabling key are further located on a circuit between the power supply and the relay, when the enabling key is pressed down, the power supply provides voltage for the relay, the relay is switched to a handle position signal, and when the enabling key is not pressed down, the relay is switched to a median value signal; and the PCU is used for deciding whether to send a signal for driving the vehicle or not and sending a specific signal for driving the vehicle according to a signal switched by the relay. The PCU can judge whether the handle power supply circuit is normal or not, and the signal sent by the PCU is an accurate handle position signal, so that the safety of driving a vehicle is improved.

本发明提供了一种使用手柄信号驱动车辆的系统，包括：手柄，用于发出手柄位置信号，手柄位置信号包括推杆信号或拉杆信号；中位值产生电路，用于产生中位值信号；使能按键，位于供电电源和手柄之间的线路上，使能按键按下时，供电电源给手柄提供电压；继电器，使能按键还位于供电电源和继电器之间的线路上，使能按键按下时，供电电源给继电器提供电压，继电器切换到手柄位置信号，使能按键未按下时，继电器切换到中位值信号；PCU，用于根据继电器切换的信号决定是否发出驱动车辆的信号以及发出具体的驱动车辆的信号。本发明的PCU可以判断手柄供电电路是否正常，并且，PCU发出的信号是准确的手柄位置信号，提高了驱动车辆的安全性。
