Abstract
In wheel ground-contact state judging device and method, a detector directly detects a lateral force acting in a direction perpendicular to the wheel center plane of a wheel. An acceleration sensor detects an acceleration in the lateral direction of a vehicle. A calculator calculates a cornering force acting on each wheel on the basis of the acceleration in the lateral direction thus detected. A judging unit compares the detected lateral force with the calculated cornering force to judge whether the ground-contact state of the wheel is good or not.
