The invention relates to the technical field of vehicles, and provides a steering control system and a steering control method for a bidirectional ferry vehicle. The steering control system of the bidirectional ferry vehicle comprises a first axle, a second axle, an axle locking pump, a steering pump, a first axle steering gear, a second axle steering gear, a first axle axle locking oil cylinder, a first axle hydraulic lock, a second axle hydraulic lock and a second axle axle locking oil cylinder, and before the first axle executes steering, the axle locking pump is selectively communicated with the first axle hydraulic lock; the first axle hydraulic lock is opened, and meanwhile, the steering pump is selectively communicated with the first axle steering gear; before the second axle executes steering, the axle locking pump selectively communicates with the second axle hydraulic lock, so that the second axle hydraulic lock is opened, and meanwhile the steering pump selectively communicates with the second axle steering gear. The bridge locking can be achieved through the hydraulic lock without hydraulic pressure, the situation that high-pressure hydraulic oil leaks is avoided, the bridge locking reliability is higher, and the safety of vehicle running is effectively improved.
本发明涉及车辆技术领域,提出了一种双向摆渡车转向控制系统及转向控制方法。该双向摆渡车转向控制系统,包括第一车桥、第二车桥、锁桥泵、转向泵、第一车桥转向器、第二车桥转向器、第一车桥锁桥油缸、第一车桥液压锁、第二车桥液压锁和第二车桥锁桥油缸,在第一车桥执行转向之前,锁桥泵选择性连通第一车桥液压锁,使第一车桥液压锁打开,同时转向泵选择性连通第一车桥转向器;在第二车桥执行转向之前,锁桥泵选择性连通第二车桥液压锁,使第二车桥液压锁打开,同时转向泵选择性连通第二车桥转向器。利用液压锁在无液压压力时就能实现锁桥,避免出现高压液压油泄露的情况,锁桥可靠性更高,有效提高车辆行驶的安全性。
