Problems solved by technology

[0005] A disadvantage of the known method is that a small deflection of the brake signal generator can hardly be detected or still does not cause a noteworthy brake pressure
As a result, delays in processing the braking request occur, in particular at the beginning of the braking process initiated by the driver
Furthermore, in the known method only the information for actuating the brake signal generator can be transmitted, ie either the offset of the brake signal generator or the actuated pressure or speed

Embodiment Construction

[0032]A braking system incorporated in current vehicles is an electronic braking system (EBS). Pneumatic systems predominate here in the case of heavy vehicles, such as in particular trucks and buses.

[0033] Such braking systems often have various additional functions. An important addition is the anti-lock braking system (ABS). However, other additional functions are also implemented here, such as roll prevention, starting assistance and similar comfort functions.

[0034] Such an electronic brake system has at least one brake control device which monitors all important functions of the brake system. In particular, the brake pressure of the individual axles or of the wheels on these axles is adjusted. In the case of the above-described comfort functions, a corresponding adjustment of the calculated brake pressure can then be carried out in order to fulfill these comfort functions.

[0035] In order to initiate the braking process, the braking request of the driver of th...

Abstract

The invention relates to a method for operating the brakes of a motor vehicle having: at least one electronic brake signal generator, in particular at least one brake pedal; and a brake control device for A brake signal from the generator is used to actuate the brake, wherein the brake signal is transmitted to the brake control unit. The method according to the invention is characterized in that the actuation of the brake signal generator and the value of the brake pressure are transmitted as brake signals to the brake control system. Finally, the invention relates to a vehicle control unit and a vehicle for carrying out the method according to the invention.

Description

technical field [0001] The invention relates to a method for operating the brakes of a motor vehicle having at least one electronic brake signal generator. The invention also relates to a vehicle control device, in particular a brake control device. The invention also relates to a vehicle having at least one brake signal generator and at least one brake control device as vehicle control device. Background technique [0002] Complex control and regulation processes in the electronic brake system (EBS) of a vehicle are usually carried out by means of a corresponding brake control device. The braking systems mentioned here are generally designed as pneumatic braking systems for heavy vehicles such as trucks, buses and the like. [0003] In addition to regulating the brake pressure to perform the braking process, in modern electronic braking systems there is usually at least an anti-lock braking system (ABS) and other safety and comfort functions. In such an ABS system, as in...
