Embodiment Construction

[0024] figure 1 A parking brake 2 of a motor vehicle is shown in schematic form. The parking brake 2 is used to permanently lock the wheels 4 a , 4 b of a vehicle axle 6 of the motor vehicle and includes corresponding actuators 8 a , 8 b for this purpose. Control signals 10 a and 10 b are supplied by a control device 12 to actuators 8 a and 8 b. Depending on the state 14 of the operating element 16 , the control device 12 determines the control signals 10 a and 10 b. The operating element 16 is arranged to be accessible by the driver of the vehicle. The state 14 of the operating element 16 determines the actuation of the actuators 8a and 8b. Opening of the parking brake 2 includes releasing the wheels 4a and 4b for rotation. Switching off the parking brake 2 includes locking the wheels wheels 4a and 4b.

[0025] figure 2 The input unit 18 of the control device 12 is shown in schematic form and is used to explain the method for operating the parking brake 2 . The input ...

Abstract

A method for operating a parking brake (2) is provided that includes feeding a timing sequence of changes in current (24a, 24b) to terminals (22a, 22b) of an interface (20) of an operation element (16) for the parking brake (2); performing at least one current measurement (26a, 26b) at at least one terminal (22a, 22b) of the interface (20) during the feeding of one of the changes in current (24a,24b); and operating the electric parking brake (2) as a function of the current measurement (26a, 26b, 26c, 26d).

Description

technical field [0001] The invention relates to a method for operating a parking brake and a control device for operating a parking brake. Background technique [0002] DE 10 2014 204 287 A1 discloses a method for operating a motor vehicle brake system having at least one electronic parking brake with at least one actuator, wherein When a first switching signal is applied to the switching signal input, the actuator is actuated to activate the parking brake. It is proposed that the switching signal input is released in the normal operating mode to apply any desired switching signal and, in the safe operating mode, is fixed to a second switching signal different from the first switching signal, thus preventing the activation of the Actuation of the actuator for the parking brake. Contents of the invention [0003] The problem on which the invention is based is solved by the method according to claim 1 and by the control device according to the co-claims. [0004] It is pr...
