BRAKE SYSTEM AND METHOD FOR OPERATING SAME

摘要

A brake system for a motor vehicle including front wheel brakes, rear wheel brakes, and a hydraulic system supplying hydraulic fluid to the wheel brakes. An electronic brake control connected to the hydraulic system actuates the hydraulic system to build up a brake pressure and supply the wheel brakes with the hydraulic fluid. The system includes a parking brake system that activates the rear wheel brakes. The electronic brake control actuates the hydraulic system to build up a brake pressure and at the beginning of an emergency braking procedure closes valves of the hydraulic system associated with the rear wheel brakes, opens valves of the hydraulic system associated with the front wheel brakes, and activates the parking brake system while keeping the valves of the hydraulic system associated with the rear wheel brakes closed for a period of adjustable length.

主权项

1. A motor vehicle brake system comprising:
front wheel brakes; rear wheel brakes; a hydraulic system including valves, at least one valve associated with said front wheel brakes and at least one valve associated with said rear wheel brakes, said hydraulic system connected to said front wheel brakes and said rear wheel brakes; an electronic brake control connected to the hydraulic system and operable to actuate said hydraulic system to build up a brake pressure in the front wheel and rear wheel brakes; a parking brake system connected to said electronic brake control and operative to activate said rear wheel brakes whereby at the beginning of an autonomous emergency braking procedure said electronic brake control actuates the hydraulic system to close valves the hydraulic system associated with the rear wheel, activates the parking brake system, and keeps the valves of the hydraulic system associated with the rear wheel brakes closed.
