根据老年代步车的设计要求和运动特性,设计了四轮毂电机老年代步车控制系统。采用分布式控制方案,分别选用经济高效的数字信号器dsPIC30F6012A和dsPIC30F4012设计了系统主控制器和轮毂电机从控制器。主、从控制器之间采用CAN总线通讯,实现代步车的电子差速控制。试验表明,该车操纵简单,运行安全稳定,能够满足老年人代步的要求。
According to the requirements and motion characteristics of mobility scooter for the elderly people, a scooter with four in-wheel motors was designed. Choosing a distributed program, a master controller for system and four unit con- trollers for in-wheel motors with high performance digital signal processor dsPIC30F6012A and dsPIC30F4012 were de- signed. Main controller and unit controllers can communicate to each other via CAN bus, and realize the electronic differ- ential system (EDS). Experiment results show that the scooter system can be manipulated easily and run safety and stabili- ty, and the system meets all requirements of scooter for the elderly people.
