Device and method for determining at least one brake characteristic value of a hydraulic braking system of a vehicle

A method for determining at least one brake characteristic value of a hydraulic braking system of a vehicle, the method comprising:

• determining, for at least one vehicle axle of a plurality of vehicle axles, a respective vehicle axle-specific brake characteristic value, wherein each respective vehicle axle-specific brake characteristic value corresponds to a ratio between a brake pressure in all wheel brake cylinders assigned to a shared vehicle axle of the vehicle and a vehicle axle braking torque exerted on the shared vehicle axle with the aid of all the wheel brake cylinders assigned to the shared vehicle axle;
• and
• activating at least one of at least one braking system component of the hydraulic braking system and an electric motor of the vehicle usable as a generator, taking into consideration at least one of the vehicle axle-specific brake characteristic values.

A method for decelerating a vehicle with a hydraulic braking system and an electric motor usable as a generator, comprising:

• determining, for at least one vehicle axle of a plurality of vehicle axles, a respective vehicle axle-specific brake characteristic value, wherein each respective vehicle axle-specific brake characteristic value corresponds to a ratio between a brake pressure in all wheel brake cylinders assigned to a shared vehicle axle of the vehicle and a vehicle axle braking torque exerted on the shared vehicle axle with the aid of all the wheel brake cylinders assigned to the shared vehicle axle;
• and
• when a brake application of the vehicle is requested, activating at least one braking system component of the hydraulic braking system and/or of the electric motor in such a way that the vehicle is decelerated using the hydraulic braking system and/or the electric motor, at least one of the vehicle axle-specific brake characteristic values also being taken into consideration during the activation of the at least one braking system component and/or of the electric motor.
