変速車両のブレーキ制御装置。 In an automatic transmission vehicle equipped with a clutch control circuit that connects a mechanical clutch while keeping it in a half-clutch state when starting based on a detection signal from a driving state detection means of the vehicle, there is provided a means for detecting operation of a brake valve and a means for detecting the vehicle speed. A hold valve is provided in the signal pressure line that supplies the signal pressure from the brake valve to the air booster, and a magnet is connected to the operating pressure line of this hold valve. In addition to interposing a valve, based on the detection signal from the driving state detection means, when the vehicle speed is zero when the brake valve is closed, the magnetic valve is opened to supply operating pressure to the hold valve, and the brake valve is also started. 1. A brake control device for an automatic transmission vehicle, characterized in that a brake holder control circuit is provided for controlling a magnetic valve so as to close a magnetic valve and release operating pressure on a hold valve side to the atmosphere when a clutch connection is detected.
