Bulldozer steering control method and system
The invention provides a bulldozer steering control method and system. The method comprises the following steps of acquiring a steering mode of a bulldozer; acquiring a steering control command and anengine rotating speed of the bulldozer; obtaining a target steering speed of the bulldozer according to the steering mode, the steering control command and the engine rotating speed; acquiring load pressure of the bulldozer and an actual steering speed under the action of the load pressure; obtaining a steering speed difference value of the bulldozer according to the target steering speed and theactual steering speed; and adjusting the engine rotating speed and rotating speed of left and right walking motors in real time according to the steering speed difference value so as to stably control the steering speed of the bulldozer. According to the method and the system, the steering speed of the bulldozer under the load pressure condition can be automatically adjusted, so that the condition that the steering speed is too high or too low can be avoided, the working efficiency and the driving comfort of the bulldozer can be improved, in addition, the steering operation difficulty of thebulldozer can be effectively reduced, and the operation impact caused when the bulldozer is steered can be reduced.
本发明提供了一种推土机转向控制方法和系统，其中，所述方法包括：获取推土机的转向模式；获取推土机的转向控制指令和发动机转速；根据转向模式、转向控制指令和发动机转速得到推土机的目标转向速度；获取推土机的负载压力以及负载压力作用下的实际转向速度；根据目标转向速度和实际转向速度得到推土机的转向速度差值；根据转向速度差值实时调整发动机转速和左右行走马达的转速，以稳定控制推土机的转向速度。本发明能够对推土机在负载情况下的转向速度进行自动调节，从而能够避免出现转向速度过快或过慢的情况，并能够提高推土机的工作效率和驾驶舒适性，此外，还能够有效降低推土机转向操作的难度，以及减小推土机转向时造成的操作冲击。
