Abstract:
A method for verifying the parking brake force in a vehicle includes comparing a travel of a brake booster with a reference travel. The method further includes producing an error signal in case of a predetermined deviation between the travel of the brake booster and the reference travel. The vehicle includes a hydraulic vehicle brake with a brake booster and an electromechanical brake mechanism with an electric brake motor for producing a braking force to displace a brake piston.

Claim (Index 5):
The method as claimed in  claim 4 , further comprising:\n calculating a stiffness of a brake caliper of the vehicle brake from the relative displacement of the brake booster or the brake master cylinder and the pressure difference; determining from the stiffness of the brake caliper and an equivalent pressure, which corresponds to an electromechanical target parking brake force, an equivalent volume; and calculating the reference travel using: c Cal = \u0394 \ue89e \ue89e p \u0394 \ue89e \ue89e V \ue89e \u0394 \ue89e \ue89e p \u0394 \ue89e \ue89e s \u00b7 A Hz = 4 \u00b7 \u0394 \ue89e \ue89e p \ue89e \u0394 \ue89e \ue89e s \u00b7 \u03c0 \u00b7 d Hz 2 \u0394 \ue89e \ue89e V em = p em c Cal , \ue89e p em = F em A pist s ges = \u0394 \ue89e \ue89e V em A Hz wherein\n \u0394p denotes the pressure difference between the lower brake pressure and the higher hydraulic target parking brake pressure, \n \u0394s denotes the relative displacement of the brake booster for the pressure difference \u0394p, \n \u0394Vem denotes an equivalent volume, \n \u0394Hz denotes a piston area of the brake booster or the brake master cylinder, \n ccal denotes the stiffness of the brake caliper of the vehicle brake, \n Fem denotes the electromechanical target parking brake force, \n pem denotes the equivalent pressure of the electromechanical target clamping force, \n Apist denotes a brake piston area of the brake piston, and \n sges denotes the reference travel.
