Abstract

A controller for vehicle which can satisfy both high grip performance and low fuel consumption while ensuring excellent safety during running. The controller for vehicle comprises a means for calculating the coefficient of friction between the wheel and the surface of running road, a means for calculating the command value of camber angle of the wheel based on the coefficient of friction thus calculated, and a means for selecting a wheel which operates a camber angle controller based on the operating state of a brake operation member detected by a brake detection means. Based on the command value of camber angle calculated by the camber angle calculation means, a first camber angle alteration means adjusts the camber angle of the wheel selected by the wheel section means. With such an arrangement, the wheel can exhibit a coefficient of friction required for suppressing slip of wheel surely while enhancing fuel saving performance, and acceleration performance, brake performance or turning performance can be enhanced more effectively.
