Pressure control device and method for a vehicle

摘要

A pressure control device for a vehicle comprises an electronic control unit and a valve device for controllably connecting a compression chamber of the vehicle's air compressor to the vehicle's compressed-air supply and storage system. The pressure control device is configured to (i) connect the compression chamber to the compressed-air supply and storage system in a compressed-air production mode to convey compressed air from the compression chamber into the compressed-air supply and storage system, (ii) connect the compression chamber to the compressed-air supply and storage system in a compressed-air expansion mode to convey compressed air from the compressed-air supply and storage system into the compression chamber, and (iii) switch from the compressed-air production mode to the compressed-air expansion mode and vice-versa by electrically actuating one or more electrically operable valves of the valve device.

主权项

1. A pressure control device for a vehicle, the vehicle having at least one engine for generating vehicle drive power, a compressed air supply and storage installation, and a compressed air compressor coupleable to the vehicle engine, the pressure control device comprising:
at least one electronic control apparatus; and at least one valve assembly, separate from and coupleable to the compressed air compressor, for controllably connecting a compression space of the compressed air compressor and the compressed air supply and storage installation, the pressure control device being configured to: (a) connect the compression space to the compressed air supply and storage installation in a compressed air generation mode to convey compressed air from the compression space into the compressed air supply and storage installation, (b) connect the compression space to the compressed air supply and storage installation in a compressed air expansion mode to convey compressed air from the compressed air supply and storage installation into the compression space, and (c) change over between the compressed air generation mode and the compressed air expansion mode based on electrical actuation of at least one electrically actuatable valve of the at least one valve assembly using the at least one electronic control apparatus.
