ABSTRACT:
In an automatic brake system provided with a pressure source including both an oil pump and an accumulator, one or more brake systems are controlled on the basis of pump pressure smoothly at low speed, but on the basis of accumulator pressure at medium or high speed. Since the pump pressure and the accumulator pressure can be used properly according to vehicle speed, the vehicle can be braked automatically and appropriately in case of the presence of a collision against another vehicle running ahead.
