The invention discloses a vehicle multi-sensor data processing method and system based on rear wheel steering, and relates to the technical field of electric digital data processing. The vehicle multi-sensor data processing method based on rear wheel steering comprises the following steps: acquiring a timestamp offset coefficient; obtaining an error compensation accuracy coefficient; and obtaining a real-time evaluation index. According to the invention, the timestamp offset coefficient is obtained through the data synchronization period of the obtained sensor data in the sensor acquisition process, and then timestamp alignment is carried out to obtain the error compensation accuracy coefficient; and finally, the data delay duration of the sensor data to be transmitted is obtained in the data transmission process, a real-time evaluation index is obtained according to the data transmission rate, whether data processing is completed or not is judged based on the obtained real-time evaluation index, and the effect of improving the timeliness of rear wheel steering vehicle sensor data processing is achieved. The problem of low timeliness of data processing of a rear wheel steering vehicle sensor in the prior art is solved.
