Anticipatory control of the transverse vehicle dynamics in evasive maneuvers

摘要

A method for influencing the lateral dynamics of a vehicle in an evasive maneuver with the aid of a vehicle controller which controls the sideslip angle and/or the yaw rate of the vehicle, and which triggers an automatic control action when a predefined threshold value is exceeded. The driving situation is monitored with regard to an obstacle, and different interventions are carried out depending on the classification of the situation. This optimizes the interventions with regard to stability and comfort, so that an optimal behavior of the vehicle is achieved in all driving situations.

1. A method for influencing transverse dynamics of a vehicle in an evasive maneuver, the method comprising:
controlling, with a vehicle controller, at least one of a sideslip angle and a yaw rate of the vehicle; determining, by the vehicle controller, whether to automatically intervene in a driver control depending on whether a predefined threshold value is exceeded by the at least one of the sideslip angle and the yaw rate, wherein the automatic intervention is triggered when the predefined threshold value is exceeded by the at least one of the sideslip angle and the yaw rate; monitoring a vehicle environment with regard to an obstacle possibly present in a driving direction of the vehicle; estimating a risk of a collision with the obstacle; and setting a particular control behavior of the vehicle controller as a function of a dangerous situation; wherein the predefined threshold value is selected based on a speed at which the vehicle is approaching the obstacle.
