The invention provides a dumper gear shifting process control system and method, and relates to the technical field of dumper gear shifting, a first position sensor and a second position sensor are in communication connection with a VCU controller, and the VCU controller controls the gear shifting process of a dumper according to stroke signals in combination with different gear distance stroke ranges stored in a storage. And the current actual gear state of the front electric drive axle and the current actual gear state of the rear electric drive axle are determined. Each electric drive axle is provided with two gear shifting electromagnetic valves; the TMS controller controls each electromagnetic valve to execute actions, when gear shifting is executed, the VCU controller sends a control instruction to the TMS controller, and after the TMS controller receives the control instruction, the TMS controller controls the gear shifting electromagnetic valves to work according to the control instruction. According to the electric drive axle gear shifting method, free, efficient and smooth electric drive axle gear shifting can be achieved, redundancy processing under various gear retreating and gear advancing failure conditions in the gear shifting process is fully considered through a process processing mode, and it is ensured that gear shifting succeeds.

    本发明提供一种自卸车换挡过程控制系统及方法,涉及自卸车换挡技术领域,第一位置传感器和第二位置传感器分别与VCU控制器通信连接,VCU控制器根据行程信号,结合存储器储存的不同挡位距离行程范围,确定当前的前电驱动桥和后电驱动桥的实际挡位状态。每个电驱动桥上均设有两个换挡电磁阀;TMS控制器控制每个电磁阀执行动作,当执行换挡时VCU控制器发送控制指令给TMS控制器,TMS控制接收到控制指令后,按照控制指令来控制换挡电磁阀工作。本发明能实现自由,高效,平顺的电驱动桥挡位切换,并通过过程处理方式,充分考虑了换挡过程中的各种退挡,进挡失败情况下的冗余处理,来确保换挡成功。
