Embodiment Construction

[0017] Figure 1The parking brake of the motor vehicle is shown schematically 2. The parking brake 2 is used to permanently lock the wheels of the vehicle axle 6 of the motor vehicle 4a, 4b, and, for this purpose, comprising a corresponding actuator 8a, 8b. Control signals 10a and 10b are transmitted by the control device 12 to the actuators 8a and 8b. According to the state 14 of the operating element 16, the control device 12 determines the control signals 10a and 10b. The operating element 16 is arranged to be accessible by the driver of the vehicle. The operating elements 16 of the state 14 determine the manipulation of actuators 8a and 8b. The opening of the parking brake 2 includes the release of wheels 4a and 4b for rotation. The closing of the parking brake 2 includes locking wheels 4a and 4b.

[0018] Figure 2 The input unit 18 of the control device 12 is illustrated in a schematic form, and for illustrating a method for running the parking brake 2. The input unit 18 inc...

Abstract

A method is proposed for operating an electric parking brake (2), wherein a fault (40) is determined with respect to a first control unit (28), which operates the electric parking brake in normal operation. parking brake (2), - wherein, depending on the determined fault (40), the second control unit (38) is operated in emergency operation, - wherein the second control unit (38) operates in the emergency mode A state (34) is determined during operation for an operating element (16) of the parking brake (2), and - wherein, depending on the state (34) of the operating element (16), the A second control unit (38) activates the parking brake (2) in the emergency mode.

Description

Technical field [0001] The present invention relates to a method for running a car brake and a control unit for running a parking brake. Background [0002] DE 10 2014 204 287 A1 discloses a method for operating a motor vehicle brake device, the motor vehicle brake device having at least one electronic parking brake, the parking brake having at least one actuator, wherein the first switching signal is applied at the input of the switching signal, the actuator is manipulated to activate the parking brake. It is proposed that the switching signal input is released in normal operation to apply any switching signal, and, in the safe operation mode is fixed to a second switching signal different from the first switching signal, thereby preventing the operation of the actuator for activating the parking brake. Contents of the Invention [0003] The problems based on the present invention are solved by a method according to claim 1 and by a control unit according to the juxtaposition c...
