US 7,248,956 B2 · Adaptation of a vehicle stabilizing system to the surface

Abstract

A vehicle stabilizing system, for motor vehicles in particular, includes a control unit in which a stabilization control algorithm is stored, a sensor system for detecting present actual values of vehicle state variables, and at least one actuator for implementing a stabilizing intervention when an unstable situation is detected. In order to be able to adapt the vehicle stabilizing system to different types of surfaces, a device is provided which supplies the control unit with information concerning the nature of the surface and at least one controller variable of the stabilization control algorithm is changed as a function of the supplied surface information.

Dependent claims

A vehicle stabilizing system comprising:

a control unit for storing a stabilization control algorithm;
a sensor system for detecting present actual values of driving state variables;
at least one actuator for implementing a stabilizing intervention when an unstable driving situation is detected;
and
a device for supplying information concerning the nature of a driving surface to the control unit,
wherein the control unit sets at least one controller variable of the stabilization control algorithm as a function of the information supplied, and wherein the stabilization control algorithm is adapted only if the vehicle stabilizing system is not active and no stabilizing intervention is immediately imminent.
