The invention provides a CAN bus signal analysis method, device and system based on a multi-core SoC. The method comprises the steps that a first signal of a CAN bus is acquired through an MCU, and the first signal is a CAN signal; the first signal is converted into a second signal through the MCU, and the second signal is an ETH signal; the second signal is sent to the MPU; converting a second signal through the MPU to obtain the first signal; the first signal is analyzed through the MPU, an analysis result is obtained, and the analysis result comprises a signal value of the first signal; and updating the signal value to the corresponding signal value storage area. 本申请提供一种基于多核SoC的CAN总线信号解析方法、装置和系统。该方法包括：通过MCU获取CAN总线的第一信号，其中，所述第一信号为CAN信号；通过所述MCU将所述第一信号转化为第二信号，其中，所述第二信号为ETH信号；将所述第二信号发送至MPU；通过所述MPU对第二信号转化得到所述第一信号；通过所述MPU对所述第一信号解析，得到解析结果，其中，所述解析结果包括所述第一信号的信号值；将所述信号值更新至对应的信号值存储区。
