Method for adjusting electronics stability control for motor vehicle, involves redetermining vehicle model parameter that describes driving behavior, for existing curve direction, where parameter represents rear axle tire stiffness

摘要

The method involves regulating a difference between a measured actual yaw rate and a desired yaw rate by a driver-independent intervention in a wheel brake and/or a steering, where the desired yaw rate is computed based on a vehicle model i.e. dynamic track model. A determination is made to check whether a quasi steady-state cornering is present such that a vehicle model parameter that describes a driving behavior of the vehicle is redetermined for an existing curve direction. A lateral tire stiffness of a rear axle is represented by the vehicle model parameter. An independent claim is also included for a system for adjusting a driving dynamics control for a vehicle.
