The invention discloses an AEBS trigger event data storage and reading method and system, and relates to the field of electronics and electrics, the method is carried out based on an SOC and an MCU, data interaction is carried out between the SOC and the MCU through an internal CAN or SPI, an EMMC used for storing data is built in the SOC, and the AEBS trigger event data storage and reading methodcomprises event storage and event reading; the event storage comprises the steps that an MCU periodically initiates an event storage instruction and sends acquired trigger event information to an SOC; and the SOC receives the event information and stores the received event information in the EMMC. According to the invention, recovery and tracing of subsequent accident events can be effectively ensured.
