Vehicle positioning control apparatus
First Claim
1. 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.

Abstract
A vehicle positioning control apparatus includes a vehicle positioning detection means, a vehicle positioning sudden change detection means, a tire air pressure reduction detection means, and a plurality of tire air pressure adjustment mechanisms. The vehicle positioning detection means detects a physical quantity indicating a positioning of a vehicle. The vehicle positioning sudden change detection means detects sudden changes in the positioning based on the physical quantity. The tire air pressure reduction detection means detects which of a plurality of wheels has undergone a reduction in tire air pressure. When a sudden change in positioning is detected, all wheels other than the wheel having undergone a reduction in pressure are designated as pressure reduction target wheels. The tire air pressure of the pressure reduction target wheels is reduced by the tire air pressure adjustment mechanisms.

6. A method of controlling a positioning of a vehicle comprising:
-
detecting a physical quantity indicating a positioning of the vehicle;
detecting a sudden change in said positioning of said vehicle based on said physical quantity;
providing one of a plurality of tire air pressure adjustment mechanisms at each of a plurality of wheels of the vehicle;
detecting a subject wheel of said plurality of wheels, said subject wheel having undergone a reduction in tire air pressure compared to the other wheels;
designating all of said plurality of wheels other than said subject wheel as pressure reduction target wheels; and
reducing the tire air pressure of said pressure reduction target wheels by actuating each of said tire air pressure adjustment mechanisms associated therewith. - View Dependent Claims (7)
