Abstract: PROBLEM TO BE SOLVED: To preclude an uncomfortable feeling of a driver by preventing a master cylinder from being communicated with a stroke simulator when a control means is started by a starting means, and further stroking a brake operating element such as a brake pedal.
SOLUTION: When the brake pedal 12 is pressed beyond a prescribed amount (S20) and an electronic control device 78 is started by pressing the pedal 12 (S30), an electromagnetic opening/closing valve (ordinarily closed valve) 26 is maintained in a closed state, and the master cylinder 14 and the simulator 28 are disconnected. In that situation, electromagnetic opening/closing valves (cut-off valves) 24L, 24R are closed or maintained in closed states (S90) unless the pedal is released (S40). The braking force of each wheel is controlled by a brake-by-wire method in a brake pedal pressing startup control mode based on final target deceleration Gt calculated based on the average value Pma of master cylinder pressure Pm1 and Pm2 (S100-130).

Abstract: PROBLEM TO BE SOLVED: To provide a vehicle brake control device ready for an electronic-controlled brake capable of determining abnormality of a stroke simulator part.
SOLUTION: In an electronic-controlled brake system capable of controlling the braking force by adjusting the hydraulic pressure to be applied to wheel cylinders 48FL-RR by a pressure source 4 and a hydraulic control unit 6, the hydraulic pressure applied to the wheel cylinder 48FL is boosted by the pressure source 4 when a brake is not in operation while a vehicle is stopped. Then, a master cut valve 20 is opened to release the hydraulic pressure to a master cylinder 14. By examining the change in the master pressure by a master pressure sensor 24, abnormality of a stroke simulator 18 and a simulator cut valve 16 is determined.

Abstract: PROBLEM TO BE SOLVED: To reduce flowing of hydraulic fluid of high pressure to a master cylinder when unnecessarily opening a cut-off valve and fluctuation of reaction of a brake pedal and energy loss caused by the flowing.
SOLUTION: Target wheel cylinder pressure Pti of each wheel is calculated according to braking manipulated variable of a driver (S20). Wheel cylinder pressure Pi is controlled to be the target wheel cylinder pressure Pti (S30 to S60). When voltage of a battery power source 96 is temporarily lowered and there is a possibility of unnecessarily opening solenoid opening/closing valves 24L and 24R as the cut-off valves when starting an engine, a ratio of pressure within each wheel cylinder in relation to the braking manipulated variable of the driver is controlled to be a smaller value (S30, 50) as compared with a normal control time (S40) of braking force. As a result, pressure and flow rate of oil flowing to the master cylinder 14 are reduced.

Abstract: PURPOSE:To prevent the engine stall in simple ways and obtain a small-sized hydraulic pump for controlling a stabilizer by reduction-correcting the torsion quantity of the stabilizer according to the reduction of the number of revolution of an engine mounted onto a vehicle. CONSTITUTION:The torsion quantity of a stabilizer M0 for jointing the right and left spring lower members in a vehicle is determined by a means M1 according to at least the car speed and steering angle. The stabilizer M0 is adjusted by a means M2 according to the determined torsion quantity. In this constitution, the number of revolution of an engine mounted on the vehicle is detected by a means M3. The torsion quantity of the stabilizer M0 is reduction-corrected by a means M4 according to the reduction of the detected number of revolution of the engine. Therefore, when the number of revolution of the engine reduces, engine stall can be prevented even if idle-up is not executed. Therefore, a hydraulic pump for controlling the stabilizer can be made small-sized.
