The invention discloses a double-steering-wheel instructional vehicle steering system, which utilizes an original double-steering-wheel system and reserves a main steering wheel system, a steering gear box assembly, an auxiliary steering wheel system and a steering reverser of a learner. An electric booster is additionally arranged on a transverse connecting rod, the electric booster judges the steering state of a current vehicle in real time, and when it is detected that a co-driver coach emergently intervenes in steering, a controller determines target current of a driving motor according toam assisting characteristic curve stored inside the controller, and the driving motor provides proper assisting torque for steering of a co-driver end; when the controller does not detect intervention of a co-driver and the vehicle is normally steered by a learner driver, the controller does not output current, does not drive the motor and does not output torque, so that the steering of the driver is not influenced; or the controller outputs a certain compensation current to compensate large frictional resistance brought by the double-steering-wheel system, so that the driver steering is light.
本发明公开了一种双方向盘教练车转向系统,利用原有双方向盘系统,保留学员的主方向盘系统、方向机总成、副方向盘系统、转向换向器。在横向连接杆上增加一个电动助力器,电动助力器实时判断当前车辆的转向状态,当检测到副驾驶教练员紧急介入转向时,控制器根据内部存储的助力特性曲线,确定驱动电机的目标电流,驱动电机,为副驾驶端转向提供适当的助力扭矩;控制器未检测到副驾驶介入,车辆由主驾驶学员正常转向时,控制器不输出电流,不驱动电机,无扭矩输出,确保主驾驶转向不受影响;或控制器输出一定的补偿电流,补偿双方向盘系统带来的较大摩擦阻力,使主驾驶方向轻便。
