Abstract
A method for operating a braking system of a motor vehicle with at least one hydraulically actuable wheel brake, a brake actuation device for hydraulically actuating the wheel brake, an electric brake booster for setting a predefinable hydraulic braking boost, and at least one parking brake assembly includes monitoring the motor vehicle to detect standstill and monitoring the parking brake assembly to detect activation thereof. The method further includes reducing a braking boost set by the brake booster if standstill of the motor vehicle has been detected and an activation of the parking brake assembly has been detected.

A method for operating a braking system of a motor vehicle, the braking system including at least one hydraulically actuable wheel brake, a brake actuation device for hydraulically actuating the wheel brake, an electric brake booster for setting a predefinable hydraulic braking boost, and at least one parking brake assembly, the method comprising:
- monitoring the motor vehicle to detect standstill;
- monitoring the parking brake assembly to detect an activation thereof;
- and
- reducing a braking boost set by the brake booster if the standstill of the motor vehicle has been detected and the activation of the parking brake assembly has been detected,
- wherein the activation of the parking brake assembly is determined in dependence on an operating state of an electric actuator of the parking brake assembly, the actuator configured to generate a locking brake force of the parking brake assembly.
A control device for operating a braking system of a motor vehicle, the braking system including at least one hydraulically actuable wheel brake, a brake actuation device for hydraulically actuating the wheel brake, an electric brake booster for setting a predefinable hydraulic braking boost, and a parking brake assembly having an electric actuator associated with the wheel brake and separately actuable from the hydraulic actuation of the wheel brake, the control device specifically-configured to:
- monitor the motor vehicle to detect standstill;
- monitor the parking brake assembly to detect an activation of the parking brake assembly via the electric actuator;
- and
- reduce a braking boost set by the brake booster if the standstill of the motor vehicle has been detected and the activation of the parking brake assembly has been detected.
A braking system for a motor vehicle, comprising:
- at least one hydraulically actuable wheel brake;
- a brake actuation device configured to hydraulically actuate the wheel brake;
- an electric brake booster configured to set a predefinable hydraulic braking boost;
- a parking brake assembly integrated with a housing of the wheel brake and configured to separately actuate the wheel brake;
- and
- a control device configured to carry out a method for operating the braking system, the control device specifically-configured to:
- monitor the motor vehicle to detect standstill,
- monitor the parking brake assembly to detect an activation thereof, and
- reduce a braking boost set by the brake booster if the standstill of the motor vehicle has been detected and the activation of the parking brake assembly has been detected.
