Abstract
PURPOSE:To detect a condition of a slip of a wheel without using acceleration signals by comparing false speed signals, a rising rate thereof is limited to a fixed value, with the speed of the wheel. CONSTITUTION:Wheel speed signals VW obtained by means of a F-V converter 2 are changed into signals higher only by DELTAV by means of an adding circuit 3. The signals are inputted to a +G gradient limit circuit 4, and used as the false speed signals VT. The signals are inputted to a comparator 5 together with the wheel speed signals VW. When the wheel speed signals exceed the false speed signals VT, slip signals S are outputted, and a driving force reducer 7 is operated. Since the false speed signals VT are set employing a limit of the acceleration of a car as the reference, the wheel can be decided as being brought to the condition of the slip when the speed of the wheel exceeds the signals VT, and malfunction is not generated because the acceleration signals are not used.
