The invention provides a redundant steering system, a mining dump truck, a control method and a readable storage medium. The redundant steering system comprises a first steering gear, a second steering gear and a whole truck controller. The first diverter includes a mode selection valve, a proportional valve, and a first controller. The mode selection valve has a power-on state and a power-off state, the proportional valve is used for being connected with the oil pump and the booster cylinder, and the first controller is electrically connected with the mode selection valve. The second steering gear comprises a rotary valve, a driving assembly and a second controller. The rotary valve is used for being connected with the oil pump and connected with the proportional valve, the driving assembly is connected with the rotary valve, and the second controller is electrically connected with the driving assembly. The vehicle control unit is electrically connected with the first controller and the second controller, and the vehicle control unit has a first working mode and a second working mode. According to the technical scheme, the first steering gear serves as the main steering gear, and the second steering gear serves as the redundant steering gear. And under the condition that the first steering gear fails, the second steering gear can continue to work to achieve the steering function.
本发明提供了一种冗余转向系统、矿用自卸车、控制方法和可读存储介质,冗余转向系统包括第一转向器、第二转向器和整车控制器。第一转向器包括模式选择阀、比例阀和第一控制器。模式选择阀具有得电状态和失电状态,比例阀用于连接油泵以及助力缸,第一控制器与模式选择阀电连接。第二转向器包括转阀、驱动组件和第二控制器。转阀用于连接油泵,转阀与比例阀连接,驱动组件与转阀连接,第二控制器与驱动组件电连接。整车控制器与第一控制器以及第二控制器电连接,整车控制器具有第一、第二工作模式。本发明的技术方案中,将第一转向器作为主转向器,第二转向器作为冗余转向器。在第一转向器失效的情况下,第二转向器能够继续工作以实现转向功能。
