Embodiment Construction

[0040] In the following drawings, the same reference numerals designate the same or equivalent parts. Events, situations or the like described below may be regularly detected by sensors provided in the vehicle.

[0041] figure 1 A flowchart of a method for implementing a trailer test function is shown. figure 1 The shown method 102 is able to carry out the trailer test function in the electrically actuatable parking brake system at least partially independently after the start of the method. Method 102 can be carried out, for example, by a control device of an electrically actuatable parking brake system, wherein the control device can be designed to carry out method 102 . figure 1 The illustrated method 102 may begin, for example, at step 200 . Starting from step 200 , it can be checked in step 202 whether a trailer test is to be carried out, for example by means of a trailer test function. The automatic implementation of the trailer test can be initiated, for example, by...

Abstract

The invention relates to a method (102) for operating an electrically actuated parking brake system (100) of a vehicle (104) including a towing vehicle (106), wherein by activating an electrically actuated parking brake system (100) The parking brake system (100) is operated to initiate execution of the trailer test function. It is conceivable according to the invention that the execution of the trailer test function is stopped and / or interrupted when at least one of the following conditions is met: - the service brake (110) of the vehicle (104) is activated, - The transmission is engaged, - the supply pressure to the electrically actuated parking brake system (100) is too low, - the vehicle (104) is moving, - the electrically actuated parking brake system (100) ) is released, - a fault is detected. The invention also relates to a control device for an electrically actuable parking brake system (100).

Description

technical field [0001] The invention relates to a method for operating an electrically actuatable parking brake system of a vehicle, including a towing vehicle, wherein the execution of a trailer test function is carried out by activating the electrically actuatable parking brake system start up. [0002] The invention also relates to a control device for an electrically actuatable parking brake system of a vehicle, including a traction vehicle, which control device is designed to carry out the method according to the invention. Background technique [0003] A vehicle, such as a commercial vehicle driven on land, may include a towing vehicle and a trailer coupled to the towing vehicle. In order to brake such a vehicle safely, service brakes for braking the towing vehicle and the trailer are usually provided. Furthermore, independently of the service brakes, there is usually a parking brake system that immobilizes the vehicle in a parked state to prevent uncontrolled coasti...
