The invention provides an intelligent steering system of a pure electric bus, which comprises a steering transmission shaft and a power steering gear which are connected with each other, and also comprises a steering motor, a driving position detection module, a motor controller and a whole bus controller, and is characterized in that the steering motor is in driving connection with the steering transmission shaft; the driving position detection module collects driving position information of the pure electric bus in real time and sends the driving position information to the whole bus controller. The whole vehicle controller judges whether the passenger car steers or not according to the driving position information, the steering angle and the steering speed to obtain a steering instruction, and the steering instruction is sent to the steering motor through the motor controller; the steering motor controls the power steering gear through the steering transmission shaft. The power assisting device has the advantages of achieving automatic steering, light steering, speed-following power assisting and active returning functions, being compact in structure and the like.

    本发明提供一种纯电动客车智能转向系统,包括相互连接的转向传动轴和动力转向器,还包括转向电机、行驶位置检测模块、电机控制器和整车控制器,其中,所述转向电机与所述转向传动轴驱动连接;所述行驶位置检测模块实时采集纯电动客车的行驶位置信息,并发送至所述整车控制器;所述整车控制器根据行驶位置信息判断客车是否转向、转向角度及转向速率以获得转向指令,将转向指令通过电机控制器发送至所述转向电机;所述转向电机通过所述转向传动轴控制所述动力转向器。本发明具有实现自动转向、轻便转向、随速助力及主动回正功能,且结构紧凑等优点。
