Problems solved by technology

Such an approach cannot be applied to today's Motor-on-Caliper (MoC) APBs because the design does not contain the same components
[0004] However, since for MoC parking brakes the piston is moved when the clamping force is built up and thus the volume is displaced, monitoring, such as for example leakage monitoring, can play a role during the actuation of the MoC parking brake.

Embodiment Construction

[0050] figure 1 A schematic sectional view of a braking device 1 for a vehicle is shown. The braking device 1 here has an automated parking brake 13 (also referred to as automatic parking brake or automated parking brake, APB for short), which can be activated by means of an electromechanical actuator. 2 (electric motor) to apply the clamping force used to hold the vehicle in place. For this purpose, the electromechanical actuator 2 of the parking brake 13 shown drives a spindle 3 , in particular a threaded spindle 3 , which is supported in the axial direction. On its end facing away from the actuator 2 , the spindle 3 is provided with a spindle nut 4 , which bears against the automated parking brake 13 in the pressed state. Piston 5 on. In this way, the parking brake 13 transmits force to the brake linings 8 , 8 ′ or the brake disk 7 . In this case, the spindle nut bears against the inner end face of the brake piston 5 (also referred to as the rear side of the brake pisto...

Abstract

The invention relates to a method for detecting leaks in a hydraulic brake system in a vehicle having a hydraulic service brake and an automated parking brake, the parking brake having an electromechanical actuator and the The service brake also acts on the same brake piston, wherein the method is characterized in that the actuation of the automated parking brake is taken into account in the evaluation of the leakage presumption. Furthermore, an apparatus, a computer program, and a storage medium are provided.

Description

technical field [0001] The invention relates to a method for detecting leaks in a hydraulic brake system in a vehicle having a hydraulic service brake and an automated parking brake, the parking brake having an electromechanical actuator and the The service brake also acts on the same brake piston, wherein the method is characterized in that the actuation of the automated parking brake is taken into account in the evaluation of the leakage presumption. Furthermore, an apparatus, a computer program, and a storage medium are provided. Background technique [0002] So-called caliper-integrated motor parking brakes are known from the prior art, as disclosed, for example, from patent application DE 10 2011 004 772 A1. [0003] Furthermore, the patent application DE 10 2004 062 824 A1 is known from the prior art. This document relates to a method for checking a parking brake. The method is used to check the functional capability of the pressure build-up in the parking brake. C...
