When a driver returns an accelerator pedal, preliminary pressure increase means increases a line pressure to a preliminary pressure increase value according to the speed of return of an accelerator pedal detected by an accelerator pedal return speed sensor, and subsequently when a braking state sensor detects that the speed of depression of a brake pedal is a predetermined value or above, pressure increase when braking means further increases the line pressure from the preliminary pressure increase value to a slip preventing pressure increase value. In this way, since the line pressure is increased to a preliminary pressure increase value when it is predicted that braking will be carried out subsequent to an accelerator pedal return operation, when subsequently there is sudden braking it becomes possible to increase the line pressure to a slip preventing pressure increase value that can prevent an endless belt from slipping with good responsiveness, thereby preventing effectively the endless belt from slipping accompanying sudden braking. |
