PROBLEM TO BE SOLVED: To provide a camber angle controlling device achieving fuel consumption saving performance, while securing turning performance of a vehicle. SOLUTION: When a camber angle imparting device 4 is controlled and a camber angle is imparted to each of wheels 2, a grounding ratio of a first tread 21 and a second tread 22 of each of the wheels 2 are changed. By the change, a high gripping property of the first tread 21 and low rolling resistance of the second tread 22 can be separately used, and fuel consumption saving performance can be achieved, while securing the turning performance of the vehicle 1. The grounding ratios of the turning outer wheels and the grounding ratios of the turning inner wheels are respectively and separately changed, and thereby the grounding ratios of the turning outer wheels and the grounding ratios of the turning inner wheels can be properly changed according to turning degrees, as compared with when the grounding ratios of the turning outer wheels and the grounding ratios of the turning inner wheels are made constant. As a result, the turning performance and fuel consumption saving performance can be improved. COPYRIGHT: (C)2009,JPO&INPIT |
