The invention discloses a steering control device and method in the urgent deceleration process of a truck. The steering control device comprises a control unit and a steering restraining mechanism. The steering restraining mechanism is installed on a steering transverse pull rod of the front axle assembly and comprises a mechanism body, an air cylinder and a V-wedge-shaped sliding block, the steering transverse pull rod is sleeved with the mechanism body, and a conical boss is coaxially arranged on the steering transverse pull rod. The air cylinder is arranged on the outer side of the mechanism body, a piston rod of the air cylinder is connected with a push plate, a plurality of guide rods are arranged on the push plate, the guide rods extend into the mechanism body and are connected with the V-wedge-shaped sliding block, a V-shaped clamping groove is formed in the side, facing the conical boss, of the V-wedge-shaped sliding block, and the V-shaped clamping groove is matched with the conical boss. Under the condition that the truck runs at a high speed and decelerates suddenly, it can be automatically ensured that the steering wheels of the truck do not deviate, serious accidents such as sideslip, overturning and collision are avoided, the operation difficulty of a driver can be lowered, the control requirement of a high-level automatic driving system is met, and the driving safety is improved.

    本发明公开了一种卡车急减速过程中的转向控制装置及方法,该装置包括控制单元和转向抑制机构;转向抑制机构安装在前桥总成的转向横拉杆上,其包括机构本体、气缸以及V楔形滑块,机构本体套设在转向横拉杆上,转向横拉杆上设有同轴设置的锥形凸台;气缸设置在机构本体的外侧,且气缸的活塞杆连接有推板,推板上设有多根导杆,导杆延伸至机构本体的内部,并与V楔形滑块连接,V楔形滑块面向锥形凸台的一侧设有V型卡槽,V型卡槽与锥形凸台相互配合。本发明可以在卡车高速行驶急减速情况下,自动确保车辆转向轮不跑偏,避免发生侧滑、翻转及碰撞等严重事故,可以降低司机的操作难度,满足高级别自动驾驶系统的控制需求,提升行车安全性。
