A brake system for a motor vehicle, having a first hydraulic brake device configured to brake wheels on a first axle of the motor vehicle, a first control unit configured to control the braking operation of the wheels on the first axle; and a second hydraulic brake device configured to brake the wheels on a second axle of the motor vehicle, and a second control unit configured to control the braking operation of the wheels on the second axle. The first control unit is coupled with the second control unit via a communication channel. The first control unit and the second control unit are each configured to receive data that are relevant for the control of the braking operation, the first control unit furthermore being configured to transmit a data signal on the basis of the received data via the communication channel to the second control unit.

Brake system and method for braking a motor vehicle

A brake system for a vehicle having a master brake cylinder, which provides a pressure signal, having a brake-medium reservoir connected to the master brake cylinder, and a first brake circuit, which is coupled by a first input to the master brake cylinder and by a second input to the brake-medium reservoir, and having at least one first wheel-brake cylinder, which is mounted at a first wheel, in order to exert a force corresponding to the pressure signal onto the first wheel, and having a separator valve, which is configured between the first input and the first wheel-brake cylinder, to prevent further transmission of the pressure signal upon receipt of a supplied closing signal; and having a control valve, which is configured between the first input and the first wheel-brake cylinder; in order to control an inflow of a brake medium from brake-medium reservoir to the first wheel-brake cylinder. In addition, a method for controlling a corresponding brake system is also described.

A brake system for a vehicle having a master brake cylinder, which provides a pressure signal, having a brake-medium reservoir connected to the master brake cylinder, and a first brake circuit, which is coupled by a first input to the master brake cylinder and by a second input to the brake-medium reservoir, and having at least one first wheel brake cylinder, which is mounted at a first wheel, in order to exert a force corresponding to the pressure signal onto the first wheel, and having a separator valve, which is configured between the first input and the first wheel-brake cylinder, to prevent further transmission of the pressure signal upon receipt of a supplied closing signal; and having a control valve, which is configured between the first input and the first wheel-brake cylinder; in order to control an inflow of a brake medium from brake-medium reservoir to the first wheel-brake cylinder. In addition, a method for controlling a corresponding brake system is also described.

A brake device for motor vehicles has at least two hydraulic brake circuits which are directly connected to a master brake cylinder, as well as an additional brake circuit, which is able to be actuated via a control device, independently of the master brake cylinder. Because of the separate hydraulic brake circuits in the region of the front axle, redundancy is provided, while the third brake circuit, that is able to be actuated independently of the master brake cylinder and typically acts on the rear wheels, during automatic actuation, permits taking into account a braking effect by additional active assemblies, such as a driven generator.

Brake device for a motor vehicle having at least three brake circuits

A method for actuating a hydraulic vehicle brake system, includes a master brake cylinder with a preferably electromechanical brake booster and a wheel slip control device. The master brake cylinder is actuated simultaneously with the brake booster, and hydraulic pumps of the wheel slip control device are driven by an electric motor. Pressure builds more quickly in the wheel brakes of the vehicle brake system for safety and assistance functions that require high pressure build-up dynamic. The method also increases the wheel brake pressure using the pressure that can be generated by actuating the master brake cylinder with the brake booster.

Method for actuating a hydraulic vehicle brake system

A method for operating a hydraulic vehicle braking system that has an anti-lock control unit is disclosed. The system includes a brake master cylinder having an electromechanical brake booster. As the pressure level of the vehicle braking system decreases during an anti-lock control, in which all vehicle wheels are controlled, the boosting force of the brake booster is reduced in an anti-lock control of this type.

In a brake device for a motor vehicle having a first and a second hydraulic brake circuit, the second brake circuit is decoupled from the main brake cylinder in partial braking operations, and is operated with the aid of a pressure accumulator controlled by a control device, which takes an additional deceleration effect due to an active power component, e.g., a generator, into account.

Brake device for a motor vehicle having a pressure accumulator

In a braking device for a motor vehicle having a first group and a second group of brake circuits, each brake circuit being associated with one group of wheels, and at least the first group of brake circuit being implemented as hydraulic brake circuits, at least one group of wheels being connected to at least one operating unit, which may cause a deceleration of the wheels, the task of a comfortable connection of recuperation brake applications to conventional brake applications is achieved in that a control unit controls the brake application of the brake circuit or circuits of the second group and optionally the deceleration effect of the operating unit or assemblies, the first group of brake circuits being activatable directly by the driver using a brake operating unit.

Braking device for a motor vehicle

A control device () for a brake-power-assisted brake system of a vehicle having a first input device () for a supplied first information item () relating to a supplied assistance force (Fu) of a brake booster () of the brake-power-assisted brake system, a second input device () for a supplied second information item () relating to a total force (Fg) comprising the assistance force (Fu) and a driver braking force (FI) supplied by activation of an activation element () of the brake-power-assisted brake system, an evaluation device () which is configured to define a third information item relating to a proportional relationship between the total force (Fg) and the assistance force (Fu) taking into account the first information item () and the second information item (), and an output device () which is configured to supply at least one control signal () to at least one component () of the brake-power-assisted brake system taking into account the defined third information item relating to the proportional relationship between the total force (Fg) and the assistance force (Fu).

Control devices for a booster brake system of a vehicle and method for operating a booster brake system of a vehicle

A safety system for occupants of a vehicle having, e.g., acceleration sensors and/or pressure sensors for sensing a side crash. The safety system also includes a detector to detect the lateral velocity of the vehicle. The control of the restraining devices of the safety system is able to be influenced by the detected lateral velocity.
