Title:
負圧装置を監視するための方法、コンピュータプログラムおよび装置
Document Type and Number:
Japanese Patent JP4928051
Kind Code:
B2
Abstract:
A vacuum reservoir (22) of a pneumatically operated power assist aggregate (30) of a motor vehicle is subjected to a vacuum by an electrical suction pump (28). In order to monitor the vacuum reservoir (22) and the electric suction pump (28), the invention provides that an initial pressure in the vacuum reservoir (22) is determined. In addition, a final pressure in the vacuum reservoir (22) is determined after a defined time interval. Furthermore, the difference between the final pressure and the initial pressure is established and compared with a limiting value. When the limiting value is surpassed, a signal is generated, in particular, a warning and/or alarm signal.
