Automotive event data recording method, system and vehicle

Abstract

This invention discloses a method, system, and vehicle for recording vehicle event data, belonging to the field of vehicle accident data recording technology. When a vehicle collision event is detected, the invention sends collision event information and storage synchronization strategy information to the data recording terminal. Based on the collision event information and storage synchronization strategy information, a first data set is stored in a first non-volatile storage area at a target time. At the same target time, a second data set is stored in a second non-volatile storage area. In response to a diagnostic read command sent by the data recording terminal, the vehicle event recording data in the second data set is sent to the data recording terminal for event diagnosis and recording of the vehicle collision event data. After a collision event occurs, the data recording terminal first completes the data recording, and then performs a diagnostic read command to retrieve and re-save the record, avoiding the problem of collision event data loss if the data recording terminal is damaged.
