PURPOSE:To smoothly start a vehicle uphill, by obtaining input signals from detectors and performing control synchronously with the engagement of a friction clutch. CONSTITUTION:A vehicle is equipped with various detectors which are a vehicle speed sensor 16, an accelerator pedal sensor 20a, an engine rotational frequency sensor 19a, a brake pedal switch 1a, a gear position switch 18 and a selected position switch. An electromagnetic check valve 3 for braking is provided between a master cylinder 2 and a wheel cylinder 4. A solenoid for operating the check valve 3 is controlled by the output of an electronic controller 6. The output signals of the detectors and an operating signal for a fluid actuator 10 for a clutch are synchronized with each other to put the braking check valve 3 into and out of operation. |
