Abstract

The invention relates to the technical field of vehicle automatic driving, and discloses a sideslip compensation method for an automatic driving vehicle, comprising the following steps: establishing a relationship model among driving scenes, sideslip driving parameters, and interference parameters; obtaining an estimate at the next moment The driving scene, predicting the estimated sideslip driving parameters corresponding to the estimated driving scene according to the relationship model, and the corresponding pre-intervention parameters; obtaining real-time driving parameters, and comparing the real-time driving parameters with the estimated sideslip driving parameters, and compensate the pre-intervention parameters according to the comparison results; perform automatic driving control on the vehicle at the next moment according to the pre-compensated pre-intervention parameters. The invention can realize the pre-intervention of sideslip, reflect in time, and avoid accidents caused by sideslip.

Description

technical field [0001] The invention relates to the technical field of automatic driving of vehicles, in particular to a sideslip compensation method and system for automatic driving vehicles. Background technique [0002] Vehicle automatic driving is the product of the development of intelligent transportation integrating automatic control system, intelligent road and environmental perception technologies. Safe Driving. At present, when the vehicle is automatically driving for side-slip control, usually it can only be controlled after the side-slip occurs, and pre-intervention cannot be performed. However, the speed of the side-slip is usually faster, and a faster reaction speed is required. If the side-slip If the control is carried out after the occurrence, it is likely that the accident will occur due to untimely control. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, provide a side s...
