Abstract
A plurality of speed sensors sense rotational speeds of respective vehicle wheels including a right-hand vehicle wheel and a left-hand vehicle wheel. A speed of the right-hand vehicle wheel and a speed of the left-hand vehicle wheel are calculated on the basis of detection signals of the speed sensors. A judgment is made as to whether or not a vehicle wheel having a small tire is present in the vehicle wheels on the basis of the calculated speeds of the right-hand vehicle wheel and the left-hand vehicle wheel. In cases where a vehicle wheel having a small tire is judged to be absent, a control quantity is calculated by use of all the detection signals of the speed sensors. In cases where a vehicle wheel having a small tire is judged to be present, a control quantity is calculated by use of the detection signals of the speed sensors except the detection signal of the speed sensor of the vehicle wheel having the small tire. A controlled object is controlled in accordance with the calculated control quantity.
