A method for warming up a vacuum pump arrangement having a booster pump and a backing pump downstream of the booster pump for evacuating a process chamber includes setting the booster pump at a first speed higher than an idle speed of the booster pump when the same is in an idle mode; and controlling a backing pressure at an outlet of the booster pump within a range from 0.1 mbar to 10 mbar at least for a period of time from when the vacuum pump arrangement is activated from the idle mode to when the booster pump reaches a temperature equal to or exceeding a first predetermined threshold value. Such method is implemented in system where a controlled is configured to carry out the above-motioned actions..

Method of controlling a brake system


In a method of controlling a brake system, a basic control to operate an electric vacuum pump is performed when a booster internal pressure, i.e., an actual pressure of a negative pressure chamber of a brake booster, is larger than a target booster internal pressure, i.e., a target pressure in the negative pressure chamber. The electric vacuum pump is not operated under a predetermined condition even when the booster internal pressure is larger than the target booster internal pressure..
