| Abstract: | Based on the analysis on the currently prevalent CAN/LIN network in on-board system, a strategy for effectively realizing the low power consumption in the bus-based auto-body control system is presented. Two different ways to enter into the low-power consumption mode are designed, making use of the idle task of the operating system, and the method of using the first wakened node to wake up other nodes and finally the whole auto-body control system by LIN bus is adopted. The requirements the design poses on MCU hardware and the difficulties in software implementation are analyzed. The resuhs of practical use in a commercial vehicle show that this design can markedly reduce power consumption of auto-body control system. |
