Abstract

The present invention relates to the field of vehicle control. The present invention provides a vehicle control action correction method, device, electronic device and storage medium. The method includes the steps of: acquiring vehicle operation information, vehicle basic information, vehicle control information and corresponding sensor output from multiple observation angles. environment information, and feedback information of the process of controlling the vehicle and the environment; using vehicle operation information, vehicle basic information, vehicle control information and corresponding environmental information, and feedback information to calculate coupling parameters; based on coupling parameters to adjust historical vehicle control actions information to correct the vehicle's control actions. The invention realizes the continuous refinement and optimization of the holographic degree of the dynamic simulation model based on the sensor data flow for the mutual cooperation of the vehicle and the road, and the closed-loop sensor information system realizes the continuous approximation of the similarity of the mathematical model to the reality, and realizes the dynamic correction of the dynamic simulation model. The machine learns by itself, so as to correct the output of more accurate and efficient car control actions.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a vehicle control action correction method, device, electronic device and storage medium. Background technique [0002] The construction of smart highway traffic involves the construction of vehicles, roads, road surfaces and roadside traffic facilities, networks, edge-side equipment, cloud equipment and other equipment and facilities, and it is necessary to simulate the operation of vehicles.
