Abstract

The invention provides a safe driving control method and device. Among them, the safe driving control method includes: obtaining the driving state parameters of the vehicle; determining whether the vehicle deviates from the preset safe driving range according to the driving state parameters; if the vehicle deviates from the preset safe driving range, outputting driving warning information; It is used to indicate that the vehicle deviates from the preset safe driving range. Carry out safety verification on the driving trajectory of the vehicle through the driving state parameters of the vehicle and the preset safe driving range to determine whether the vehicle is safe to drive. The complexity of the safety verification is reduced, the stability of the safety verification is improved, and the driving safety of the vehicle is improved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving vehicles, in particular to a safe driving control method and device. Background technique [0002] The safety of autonomous vehicles is of paramount importance. When realizing automatic driving, the driving strategy algorithm generates the driving trajectory of the vehicle according to the driving environment after environment modeling. For safety reasons, it is necessary to verify the driving trajectory. When the driving trajectory meets the safety requirements, the driving trajectory is output to the subsequent control module for vehicle control. If the driving trajectory does not meet the safety requirements, which will lead to accidents or violations, the verification results will be fed back to the driving strategy algorithm and corresponding emergency measures will be implemented to avoid accidents. [0003] At present, the driving strategy algorithm and the driving traj...
