Abstract
Provided is rotational-state-of-wheel detecting apparatus that can avoid output of an incorrect rotational direction during a halt of a wheel. In ECU , a signal input section accurately detects wheel speeds and rotational directions of respective wheels , and, based on the results, respective computers execute ABS control, TC control, and VSC control. On this occasion, switching of the rotational direction is restricted with a computation result of wheel speed of zero, and it is thus feasible to prevent occurrence of a malfunction or state hunting being repetitive switching of signs, due to an external magnetic field during halts of the wheels . This further optimizes the state control of a vehicle.
