The invention discloses a vehicle data recording method, a computer readable storage medium and a vehicle, and the data recording method comprises the following steps: carrying out the cyclic coveragecaching of the output data of a sensor in an automatic emergency braking system of the vehicle through a cyclic buffer region; obtaining the working state of the automatic emergency braking system ofthe vehicle; if the working state is an early warning state or a braking state, initializing the data storage operand to obtain a first starting data storage timestamp; when the working state is changed into a standby state from an early warning state or a braking state, updating the number storage operand to obtain a first number storage stopping timestamp; and performing data recording from thecached data according to the first start storage timestamp and the first stop storage timestamp. Therefore, the data recording method of the vehicle can save data storage space, record effective datameeting development and test analysis function requirements, and provide an optimization direction for the automatic emergency braking system.
Description
Technical field [0001] The present invention relates to the field of vehicle technology, and more particularly to a data recording method of a vehicle, a computer readable storage medium, and a vehicle. Background technique [0002] AEB (Autonomous Emergency Braking, Automous Emergency Brake System) is a very important advanced driving assistance system in vehicles, and with the more mature driving technology, more and more vehicles have automatic driving functions, automatic emergency braking is also a vehicle A wide range of configurations. In order to balance costs and vehicle safety performance, there is an urgent need to solve the problem of leakage, failure scenes, and optimization of automatic emergency braking system. In the related art, it is generally a sense data of the vehicle sensor and the functional control logic state of the automatic emergency brake system, providing the rationality of the authentication of automatic emergency brake system information processing....
