PURPOSE:To prevent the generation of power-on shock during starting a vehicle, by changing over a mechanical speed reduction gear once into a high speed higher gear stage from a first gear stage when the braking condition of a brake is released under an anticreep control condition. CONSTITUTION:When the braking condition of a brake for controlling the running of a vehicle is released under an anticreep control condition, the hydraulic pressure of a forward clutch 28 is increased to a value which is established when a forward gear stage is attained, and when this hydraulic pressure reaches a predetermined value, a shift brake 30 is released. Thereby, when the braking condition of the brake is released, a mechanical speed reduction gear is once change over into a high speed gear stage, and then is changed over into a first gear stage since the shift brake 30 is released. Therefore, a shift-down is carried out in such a condition that an accelerator pedal is not yet depressed, thereby it is possible to prevent the generation of power-on shock during starting the vehicle. |
