A braking system for a motor vehicle has a plurality of hydraulic brake units for braking each braking one wheel of the motor vehicle and a first electric parking brake actuator for braking a first wheel and a second electric parking brake actuator for braking a second wheel. A first control device comprises a first hydraulic controller which is designed and set up to drive the plurality of hydraulic brake units. In order to ensure parking brake redundancy, the first control device has a driver for driving the first parking brake actuator. A second control device is also provided, which comprises a driver for driving the first parking brake actuator and a driver for driving the second parking brake actuator.

Braking system having a redundant parking brake function

A brake system for a motor vehicle has electromechanical wheel brakes, a brake operating unit and a central brake control unit. The wheel brakes each have a local brake control unit. The central brake control unit is connected to the brake operating unit and the local brake control units via a first data connection. The brake operating unit is connected to the local brake control unit of at least one wheel brake via a second data connection. In a normal operating mode the central brake control unit determines at least one brake demand from first operating information, received via the first data connection and transmits control signals corresponding to the brake demand to the local brake control units. In a fallback operating mode the local brake control units actuate the respective wheel brakes basis on second operating information, received via the second data connection.

Brake system for a motor vehicle

A method for operating a braking system of a vehicle, wherein the braking system comprises a primary hydraulic braking system and a brake actuation unit hydraulically decoupled from the primary braking system. The brake actuation unit comprises at least two sensor arrangements which are configured to detect, independently of one another, actuation information of the brake actuation unit describing a brake request. The method comprises determination of a first actuation information by a first of the sensor arrangements, determination of a second actuation information by a second of the sensor arrangements, checking whether the respective determined actuation information is valid, and if the actuation information is valid, checking whether the determined items of actuation information are mutually plausible, and implementation of the brake request according to the actuation information and/or issue of a warning and/or performance of a predefined braking maneuver by the braking system depending on the validity and plausibility of the actuation information.

Method for operating a braking system of a vehicle, and braking system

A braking system having wheel brakes, a pressure supply device connected to the wheel brakes, a master brake cylinder actuated by a brake pedal and connected to the wheel brakes, and a brake fluid reservoir having a first and a second reservoir chamber separated by a partition wall, wherein the first reservoir chamber is connected to the pressure supply device, via which the pressure supply device is supplied with pressure medium, and the second reservoir chamber is connected to the master brake cylinder, via which the master brake cylinder is supplied with pressure medium The braking system is operated in a first operating mode when the first filling level is reached and a second operating mode when the second filling level is reached, and a hydraulic fallback level if a lowest filling level is reached.

Method for operating a braking system, and braking system

A method for checking functionality of a motor vehicle braking system. The braking system has a main module, including: hydraulically actuatable wheel brakes, pairs being assigned to respective brake circuits; at least one electrically actuatable wheel valve per wheel brake sets wheel-specific brake pressures; a pressure provision device actively builds up pressure in the wheel brakes; a pressure-medium reservoir at atmospheric pressure, and an auxiliary module, which has for each of two wheel brakes: a pressure sensor for measuring pressure in a wheel brake line; an open when deenergized isolating valve in the wheel brake line; a pump. At least one variable is measured to assess functionality of the braking system. Using least one acceptance criterion, and checked whether the variable satisfies the acceptance criterion. Determining at least one variable representing the viscosity of the brake fluid, and the at least one acceptance criterion depends on a variable representing viscosity.

Method for checking the functionality of a braking system, and braking system

A brake system for a motor vehicle comprises a first brake set and second brake set. A first hydraulic brake circuit is connected to the first brake set and a second hydraulic brake circuit is connected to the second brake set. Further, a first control module is coupled to the first hydraulic brake circuit and the second hydraulic brake circuit. The first control module is configured to control fluid pressure within both the first hydraulic brake circuit and the second hydraulic brake circuit. A second control module is also coupled to the first hydraulic brake circuit and the second hydraulic brake circuit. The second control module is configured to control fluid pressure within both the first hydraulic brake circuit and the second hydraulic brake circuit independent of the first control module. The first control module is disposed in series with the second control module in the first and the second hydraulic brake circuits. Additionally, a virtual driver sends a deceleration request to the first control module and the second control module. The first control module and the second control module determine a desired pressure based upon the deceleration request. The first brake control module controls fluid pressure within both the first and the second hydraulic brake circuits to perform the deceleration request. The second control module monitors pressure downstream from the first control module and compares the monitored pressure to the desired pressure.
