<p>PURPOSE: To effectively prevent the slip of driving wheels at the time of speed change of a vehicle by providing a slip condition discriminating means for discriminating the slip condition of driving wheels on the basis of the pseudo driving wheel speed substituted for the driving wheel speed and a reference value. CONSTITUTION: The driving wheel speed computed by a driving wheel speed computing means 31 is input to a slip condition discriminating means 34 with a deceleration control starting reference value and an acceleration control starting reference value computed by a reference value computing means 33. A speed change discriminating means 36 discriminates the speed change of a transmission on the basis of the gear position detected by a gear position detecting means 3. When speed of a transmission is changed, the pseudo driving wheel speed, which is computed by a pseudo driving wheel speed computing means 37, is substituted for the driving wheel speed on the basis of the output of a first timer 38 and a second timer 39. Slip of the driving wheels is controlled on the basis of this pseudo driving wheel speed. The apparent driving wheel slip rate is thereby enlarged so as to quickly increase or decrease the driving wheel torque, and the slip of the driving wheels is effectively avoided.</p> |
