PURPOSE:To certainly release the brake pressure certainly in accordance with the actual starting operation for a car by operating a brake-pressure holding apparatus by the logic product of the detection of a certain revolution-torque value which acts onto a wheel and the detection of stepping-down of an accelerator pedal. CONSTITUTION:When a clutch is connected, and an accelerator pedal 13 is stepped-down to start a car, the revolution-torque detection signal (c) for a propeller shaft 14 supplied from a torque gauge 16 and an accelerator-pedal 13 stepping-down signal (a) are input into a control circuit 18. When a car is ready for certain start because of these signals, the control circuit 18 releases the operation signal (e) for an electromagnetic opening/closing valve 11. There fore, the valve 11 is put into communication position by a springy force, and the brake pressure is released. |
