Abstract
A vehicle control system with which different vehicle functions, such as a driving dynamics function and/or a component protection function, can be controlled, in which vehicle control system, in the case of onroad driving, an rpm-based vehicle speed determined by a wheel speed sensor forms a reference variable, on the basis of which the vehicle control system determines driving parameters and/or controls the vehicle function. The vehicle control system is assigned an evaluation unit which, in the presence of both offroad driving operation and a tire change signal, determines a GPS-based vehicle speed as a reference variable, on the basis of which the vehicle control system determines the driving operation parameters, such as an offroad tire diameter, and/or controls the vehicle functions.
Claims13
A vehicle control system configured to control different vehicle functions, wherein:
- the different vehicle functions comprise a driving dynamics function and/or a component protection function, can be controlled, in which vehicle control system
- in the case of on-road driving, an rpm-based vehicle speed determined by a wheel speed sensor forms a reference variable,
- the vehicle control system is further configured, based upon the reference variable, to determine driving parameters and/or control the vehicle function,
- assigned an evaluation unit which, in the presence of both off-road driving operation and a tire change signal, generated after a significant tire diameter deviation between off-road tires and standard tires, is configured to set a GPS-based vehicle speed as the reference variable, on the basis of which the vehicle control system is configured to determine an off-road tire diameter.
