ABSTRACT:
A tire attitude control device comprises: detecting unit that detects the respective ground contact states at two tire measurement positions on the tire shoulder side, each the same distance away from a tire center position in a direction opposite a tire width direction, at the same position in a tire peripheral direction; calculating unit that calculates the respective ground contact lengths at said two tire measurement positions at least once per tire rotation, based on said ground contact states detected by said detecting unit; and control unit that generates, when a ratio of two ground contact lengths calculated by said calculating unit is out of a predetermined range that includes 1, a control signal for controlling a camber angle of a tire so that said ratio approaches 1 and outputs the control signal to said suspension control device.
