Patent ID: 8249774

Claim:
An alignment changing control device for controlling an alignment of wheels of a vehicle, comprising: an alignment setting unit configured to set the alignment of the wheels in a traveling condition; a fuel consumption calculating unit configured to calculate a fuel consumption in the traveling condition at each of a plurality of different alignments set by the alignment setting unit; a fuel consumption information storage configured to correlate the fuel consumption calculated by the fuel consumption calculating unit at each of the plurality of different alignments with the alignment at which each fuel consumption was calculated, and to store a plurality of correlated alignments and fuel consumptions so that fuel consumption related information corresponding to each of the plurality of different alignments is stored; and a selecting unit configured to read out the fuel consumption related information from the fuel consumption information storage and to select the alignment correlated with a best fuel consumption from among the plurality of different alignments stored in the fuel consumption information storage, wherein the alignment setting unit is configured to set the wheels to the alignment selected by the selecting unit.
