Problems solved by technology

A disadvantage here is that many situations, which are influenced in particular by the user's actions, are not recognized, in which case an increased compressed air consumption is to be expected, and by increasing the compressed air fed in, partially unnecessary mechanical component aerodynamics occur. load

Embodiment Construction

[0040] according to figure 1, the compressed air system 1 of the vehicle, not shown here, comprises two compressed air accumulators 2a, 2b of two service brake circuits, one compressed air accumulator 2c of a parking brake circuit and a further consumer A compressed air storage device 2d. In this case, the compressed air storage devices 2 a , 2 b , 2 c , 2 d are supplied with compressed air by the compressor 3 separately and independently of one another. The compressor 3 is actuated by the control unit 4 in order to start or end the delivery phase of the compressor 3 for generating compressed air in one of the compressed air storage devices 2 a , 2 b , 2 c , 2 d. In this case, the control unit 4 communicates with the systems 6 a , 6 b , 6 c , 6 d via the data bus 5 . In this case, the system 6 d is designed as a human-machine interface 7 in the form of a touch-sensitive display which is directly operated by the user 8 .

[0041] In particular, the user 8 can issue a request...

Abstract

The invention relates to a method for operating a compressed air system (1) of a vehicle controlled by a user (8), comprising the following method steps: In said method steps, at least one compressed air storage device (2a; 2b) is detected ; 2c; 2d), the energy level in the electronic control unit (4) is assigned to the compressed air storage device (2a; 2b; 2c; 2d) with the upper threshold (13) and / or A lower threshold value (12) belonging to said compressed air storage device (2a; 2b; 2c; 2d) is compared, and when the energy level is lower than said lower threshold value (12), activation for said at least one compressed air storage device A compressor (3) producing compressed air in (2a; 2b; 2c; 2d), and / or in said at least one compressed air storage device (2a; 2b) when the energy level is above said upper threshold (13) ; 2c; 2d) Stop generating compressed air, wherein the compressed air demand is determined by a system (6a; 6b; 6c; 6d) communicating with the control unit (4) and the user (8), and the corresponding A data set related to the compressed air demand is sent to the control unit (4), and the lower threshold and / or the upper threshold are matched by the control unit (4) according to the data set (12; 13 ). The invention also relates to a compressed air system (1) suitable for carrying out the method.

Description

technical field [0001] The invention relates to a method for operating a compressed air system of a vehicle controlled by a user, the method comprising the following method steps: In said method steps, the energy level in at least one compressed air storage device is detected, via an electronic control unit The energy level is compared with an upper threshold value assigned to the compressed air storage device and / or a lower threshold value assigned to the compressed air storage device, compression is enabled in at least one compressed air storage device when the energy level is below the lower threshold value machine to generate compressed air, and / or stop generating compressed air in at least one compressed air storage device when the energy level is above said upper threshold. [0002] The invention also relates to a compressed air system suitable for carrying out the method. [0003] In this case, the energy level and the threshold value to which it is compared include, f...
