The hard wire output conversion method based on the CAN bus vehicle speed comprises the steps that an ECU firstly judges whether a CAN bus vehicle speed signal is received or not, if yes, the latest CAN bus vehicle speed signal is collected to determine the vehicle speed, then a hard wire output pulse signal period is determined based on the vehicle speed and an odometer coefficient, and then the ECU sends a single pulse signal according to the hard wire output pulse signal period. According to the design, simple, convenient and rapid conversion between the CAN line vehicle speed signal and the hard line vehicle speed signal is achieved.

    一种基于CAN总线车速的硬线输出转换方法,ECU先判断是否接收到CAN总线车速信号,若是,则采集最新CAN总线车速信号以确定车速,再基于车速和里程表系数确定硬线输出脉冲信号周期,然后ECU按照硬线输出脉冲信号周期发送单个脉冲信号。该设计实现了CAN线与硬线车速信号之间简便、快速的转换。
