<p>PURPOSE:To enable to suppress the slip of a vehicle to a sufficiently low value due to the reduction of a drive force of the minimum necessary limit, by suitably cooperating a slip preventive brake and a notch return in response to the slipping state. CONSTITUTION:A comparator 3 detects a slipping speed from the speed difference between a reference tachometer generator 1 and the tachometer generator 2 of a driving axle, and a differentiator 4 differentiates the output of the generator 2 to detect the acceleration. Comparison amplifiers 5, 6 respectively compare the slipping speed and the acceleration with set values 5a, 5b, and respectively apply the slip detection signals to solenoid valves 12, 13 in a slip brake 10 through an OR circuit composed of diodes 7, 8. On the other hand, the output of the comparator 3 for detecting the slipping speed is also applied to a comparison amplifier 18 to output a notch return command N when exceeding a set value 18a, thereby sequentially reducing the drive force.</p> |
