CAN BUS Based Control System of Parallel Hydraulic Hybrid Vehicle
Zhang weigang, Tsinghua University, Beijing 100084 Abstract: A CAN BUS based control system is introduced in this paper, which is designed for PHHV (Parallel Hydraulic Hybrid Vehicle). The control system adopts the distributed frame, which is more Flexible than the concentrated one. The hardware and software are designed, and especially the reliability design is introduced. The control system can meet the requirement of complicated control process of PHHV, and has well expansibility, so that will be a good application.
