Patent ID: 7224268

Claim:
A vehicle positioning control apparatus comprising: vehicle positioning detection means for detecting a physical quantity indicating a positioning of a vehicle; vehicle positioning sudden change detection means for detecting sudden changes in said positioning of said vehicle based on said physical quantity detected by said vehicle positioning detection means; tire air pressure reduction detection means for detecting which of a plurality of wheels provided on said vehicle has undergone a reduction in tire air pressure relative to tire air pressures of the other wheels; and a plurality of tire air pressure adjustment mechanisms respectively provided at the plurality of wheels to enable reduction of the tire air pressures of each of said plurality of wheels, wherein upon said vehicle positioning sudden change detection means detecting a sudden change in positioning of said vehicle, all wheels other than the wheel detected by said tire air pressure reduction detection means are designated as pressure reduction target wheels, and the tire air pressure of each of said pressure reduction target wheels is reduced by said tire air pressure adjustment mechanism provided at said pressure reduction target wheels.
