摘要
在研究CAN协议的原理及应用技术的基础上,为了满足混合动力电动车控制策略的需要,针对混合动力电动车的特点,设计了新的CAN总线应用层协议。该协议对网络信息进行了分类并进行了合理的优先权分配,而且在CAN2.0B的基础上重新定义了ID场,实现了广播式和点对点的通讯。该协议具有很强的扩展性,可以兼容OSEK-NM和CCP(CANCalibrationProtocol)协议。实验结果表明,在应用于混合动力电动车多能源动力总成的控制系统开发时,该协议具有可靠性高、网络负载小和通讯实时性好的特点。
A control area network (CAN) application layer was designed for the control network of hybrid electric vehicles (HEV). Messages in the network are classified and the priorities of messages are assigned according to their classes with the redefined ID field of CAN2.0B. The protocol includes destination specific communications and broadcast communications. Furthermore, the protocol is compliant with OSEKNM and CCP (CAN calibration protocol). Experimental results indicate that the CAN control system for the HEV powertrain is very reliable and has low network load and good realtime performance.
