Problems solved by technology

[0004]While doubling all components of the braking system to form a redundant system is effective in obtaining functionality even in the event of a failure, it is costly, structurally space- and weight, especially in mass production is disadvantageous

Embodiment Construction

[0066] figure 1 An embodiment of a braking system 80 according to the invention is shown, figure 2 show figure 1 The control connection of the brake system 80 . The following description of brake system 80 refers here to these two figures.

[0067] A front axle VA and a rear axle HA are shown, each having a wheel 1 , which is rotatably fastened on an axle 2 . The wheels 1 are each equipped with a brake device, which is embodied as a friction brake in the example shown. For this purpose, a brake disk 3 is provided on each wheel 1 , which is designed to be in frictional contact with a friction pair, in this case a brake lining 4 . The brake discs 3 are each connected in a rotationally fixed manner to the wheels 1 and thus rotate with the wheels 1 during travel.

[0068] To apply the brakes, the individual brake linings 4 are brought into contact with the corresponding brake disc 3 by the introduced brake pressure, whereby a friction force is formed on the brake disc 3 whic...

Abstract

The invention relates to a braking system (80) for a vehicle, the braking system being designed to detect at least one state variable for controlling the braking system (80), comprising: a primary control means (40) which is designed to control the braking system (80) by means of at least one actuator and taking into consideration the at least one state variable, a redundancy control means (41) which is designed to control the braking system (80) by means of a part of the at least one actuator and taking into consideration a part of the at least one state variable, wherein the braking system (80) is designed, upon the occurrence of at least one switching condition, to at least in part use the redundancy control means (41) rather than exclusively the primary control means (40) to control the braking system. The invention also relates to a method for controlling such a braking system and to a computer programme product.

Description

technical field [0001] The invention relates to a redundant braking system, in particular for road vehicles, and to a method for operating such a braking system. Background technique [0002] Commercial vehicles with highly automated driving functions that relieve the driver of control tasks and responsibility for control, at least for a limited time, i.e. can operate autonomously, for example, must continue to operate the vehicle in the event of any malfunctions until the driving The driver takes over control of the vehicle again. [0003] The resulting "failure-operating" system characteristic requires that the basic functions of the vehicle continue to be ensured, in particular at the implementation level (at least with functional limitations). Brake control in autonomous driving operation means that in the event of any malfunction the brake system can still be operated electronically, so that the driving dynamics control functions such as ABS, ASR, ESP can still be impl...
