Abstract

When a driver returns an accelerator pedal, preliminary pressure increase apparatus 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. 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 apparatus further increases the line pressure from the preliminary pressure increase value to a slip preventing pressure increase value. 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 accompanying sudden braking.
