Tire attitude control device and method

A tire attitude control device configured to control an attitude of a rolling tire mounted on a vehicle using a suspension control device that adjusts a camber angle of the tire, comprising:

• detecting means 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 means 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 means;
• and
• control means that generates, when a ratio of two ground contact lengths calculated by said calculating means 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,
• wherein said detecting means includes acceleration sensors mounted on a tire inner surface.
