Abstract

A method for operating a braking system of a vehicle, particularly of a motor vehicle, is described in which an automatic braking process is triggered by the exceeding of a specifiable threshold value by a rate of change conditioned upon the operation of a brake pedal. It is provided, in this context, that the threshold value is specified/varied by the driver in an initialization operation of the braking system. Also described is a related braking system.

First claim

What is claimed is:

1. A method for operating a braking system of a motor vehicle, the method comprising:
performing an initialization operation of the braking system in response to a driver input;
during the initialization operation, recording a rate of change of a signal that varies in dependence on driver operation of a brake pedal and setting a threshold value equal to the rate of change recorded during the initialization operation; and
triggering an automatic braking process in response to a rate of change of the signal outside of the initialization operation exceeding the threshold value.

2. The method of claim 1 , further comprising:
during the initialization operation, one of visually signaling and acoustically signaling to the driver when the rate of change has reached a previously set threshold value.

3. The method of claim 1 , wherein the threshold value is set only if it is within a specifiable boundary range.

4. The method of claim 1 , wherein the initialization operation is initiated at standstill of the vehicle by operating an operating element.

5. The method of claim 1 , wherein an accelerator of the vehicle is used to trigger the initialization operation.

6. The method of claim 1 , wherein during the initialization operation, the setting of the threshold value is enabled only after the brake pedal is operated in such a way that the rate of change exceeds the threshold value.

7. A braking system for a motor vehicle, comprising:
a brake pedal;
at least one braking device that is controllable by the brake pedal;
a recording arrangement that records a rate of change of a signal that varies in dependence on driver operation of the brake pedal; and
a braking assistant unit that compares the recorded rate of change to a specifiable threshold value, wherein the threshold value is set equal to the rate of change of the signal recorded during an initialization operation of the braking system;
wherein an automatic braking process is triggered in response to a rate of change of the signal outside of the initialization operation exceeding the threshold value.

8. A device for operating a braking system of a motor vehicle, comprising:
a specifying arrangement configured to, during an initialization operation of the braking system, record a rate of change of a signal that varies in dependence on driver operation of a brake pedal and set a threshold value equal to the rate of change recorded during the initialization operation; and
a triggering arrangement configured to trigger an automatic braking process in response to a rate of change of the signal outside of the initialization operation exceeding the threshold value.
