Abstract
PURPOSE: To perform running of a car in good efficiency of power, by surely avoiding a slip in a speed change gear, that is, by detecting occurrence of the slip in a friction transmission unit in the speed change gear and automatically operating speed change on the basis of the detection.
CONSTITUTION: The first detector 21, detecting an operational condition of speed change, is further provided to a speed change operating control valve V in a speed change gear 7. The second detector 22, detecting rotary speed, is further provided to an output shaft 12 of the speed change gear 7. Then a range of output speed, specifically determined by a speed change operational condition detected by the first detector 21, is compared with output speed detected by the second detector 21 to detect a slip in the speed change gear 7, on the basis of this detected slip the speed change gear 7 is automatically operated speed change by a controller 30. After operation of the automatic speed change, control of the automatic speed change is stopped with a control stopping mechanism 32 by a preset time to prevent an uncomfortable shock.
