摘要： A braking control apparatus for use in a motor vehicle having at least one wheel comprising a master cylinder for generating a hydraulic pressure in response to a braking operation of a vehicle driver, an accumulator for accumulating a hydraulic pressure and at least one wheel braking cylinder for braking the wheel in accordance with a hydraulic pressure supplied thereinto. A passage system is provided so that the wheel braking cylinder is communicated therethrough with the master cylinder and the accumulator. In the passage system are provided first and second change-over valves for cutting off the pressure from the master cylinder, cutting off the pressure from the accumulator and a third control valve disposed between the wheel braking cylinder and the master cylinder or the accumulator for establishing and cutting off the communication therebetween. An control unit controls the operations of the first to third valves so as to, in response to cutting off the communication with the accumulator, establish the communication with the wheel braking cylinder, and then establish the communication with the master cylinder. This valve control prevents the high-pressure remaining in the passage system after the cutting-off of the communication with the accumulator from being rapidly applied to the master cylinder.

摘要： A brake control apparatus for automotive vehicles is provided which has two separate hydraulic brake lines leading to wheel cylinders and performs a brake assisting operation to hold the wheel cylinder pressure higher than the master cylinder pressure in each of the hydraulic brake lines when a brake pedal is depressed by a vehicle operator. The brake control apparatus also includes a fluid pressure difference regulator which regulates a pressure difference between the two hydraulic brake lines so as to fall within a given allowable pressure range, thereby minimizing adverse effects on the brake assisting operation which are caused by electric and/or mechanical performance difference between the two hydraulic brake lines.

摘要： A brake fluid pressure control apparatus that can switch from brake fluid pressure control to normal brake operation immediately after the brake fluid pressure control terminates. This apparatus has a master cylinder, pressure control valves for controlling the brake fluid pressure in wheel cylinders and a pump for pumping out the brake fluid to the wheel cylinders. It also has an accumulation chamber connected to an inlet of the pump which accumulates the brake fluid in an airtight condition to generate negative pressure. Further, it has a cut-off valve for cutting off the flow of the brake fluid from the master cylinder to wheel cylinders and a return conduit connected between the wheel cylinders and the accumulation chamber.
