The invention discloses an automatic driving automobile safety device capable of preventing excited steering, which comprises a steering wheel, an upper steering shaft, a steering sensing part, a steering motor, a middle steering shaft, a lower steering shaft, a steering locking mechanism and a controller. The steering wheel and the steering motor drive the upper steering shaft to rotate; the steering sensing part is connected between the upper steering shaft and the middle steering shaft and transmits torque, the steering sensing part is used for sensing relative rotation of the upper steering shaft and the middle steering shaft and sending a left steering or right steering signal to the controller, the middle steering shaft is connected with the lower steering shaft through a universal joint, the lower steering shaft drives automobile driving wheels to steer, the steering locking mechanism is arranged on the lower steering shaft and receives a locking signal sent by the controller, and the steering locking mechanism enables the lower steering shaft to only rotate leftwards or rightwards or not to be limited according to the locking signal. The invention further discloses a control method of the safety device, the wheel steering in the direction opposite to the steering intention can be prevented, and the safety is improved.

    本发明公开了一种预防激转向的自动驾驶汽车安全装置,包括转向盘、上转向轴、转向感应部件、转向电机、中转向轴、下转向轴、转向锁止机构以及控制器,转向盘及转向电机驱动上转向轴转动,转向感应部件连接于上转向轴与中转向轴中间并传递扭矩,转向感应部件用于感应上转向轴与中转向轴的相对转动并向控制器发送左转向或右转向信号,中转向轴通过万向节与下转向轴连接,下转向轴驱动汽车驱动轮转向,转向锁止机构设置于下转向轴并接收控制器发送的锁止信号,转向锁止机构根据锁止信号使下转向轴仅能进行左转、右转或者不予限制。本发明还公开了这种安全装置的控制方法,本发明能阻止与转向意图相反方向的车轮转向,提高安全性。
