PURPOSE:To correct the wheel speeds of all the wheels, and to prevent that the wheel speeds of the wheels other than an abnormal wheel are corrected to the value higher than the actual car body speed, by converting a standard wheel in order when the wheel speeds of the wheels other than the standard wheel are corrected. CONSTITUTION:In a vehicle, the front wheels 1 and 2 at the left side and the right side are driven wheels, and the rear wheels 3 and 4 at the left side and the right side are driving wheels. The output torque of an engine 5 is transmitted from an automatic transmission 6 to the rear wheels 3 and 4 at the left side and the right side through a propeller shaft 7, a differential device 8, and the left side and the right side driving shafts 9 and 10. By making a specific wheel of the vehicle as a standard wheel 1, the wheel speeds of the remaining wheels 2 to 4 are to be corrected. In the correction of the wheel speeds of the wheels 2 to 4, by converting the standard wheel 1 in order, the wheel speeds of all the wheels 1 to 4 can be corrected. And when the vehicle installs only one wheel whose diameter is smaller owing to a puncture or the like, it is prevented that the wheel speeds of the other wheels are corrected to the speed higher than the actual car body speed, so as to improve the brake controllability. |
