Abstract
The invention relates to an electronically regulable brake system, with an actuating device, in particular a brake pedal, a main brake cylinder arrangement with at least two parallel arranged piston cylinder units and a reservoir, which are connected via hydraulic lines and valves to wheel brakes, and with a servo mechanism. According to the invention an electrically drivable valve device (BV1, BV2, EA) is provided between the brake circuits allocated to the piston cylinder units (16, 17), in order to allow the regulated transfer of hydraulic fluid between the brake circuits (bypass) and the reservoir (24).
Claims27
An electronically controllable brake system, the system including:
- an actuation device;
- a main brake cylinder arrangement including at least two parallel-arranged piston-cylinder units and a reservoir, which are connected via hydraulic lines and valves to wheel brakes;
- a servo device;
- and
- an electrically drivable valve device disposed between brake circuits allocated to the piston-cylinder units and configured to permit the regulated transfer of hydraulic fluid between the brake circuits and the reservoir.

An electronically controllable brake system, the system including:
- an actuation device;
- a main brake cylinder arrangement including at least two parallel-arranged piston-cylinder units and a reservoir, which are connected via hydraulic lines and valves to wheel brakes;
- a servo mechanism;
- and
- an additional piston-cylinder unit with at least one compensation piston arranged between brake circuits, wherein the compensation piston is arranged to separate two operating chambers that are each connected to a respective brake circuit, wherein from at least one brake circuit a hydraulic line leads to a compensation container, and wherein a valve is arranged in the hydraulic line that leads to the compensation container.
