A method for sensing travel by a travel-sensing arrangement for a brake system, wherein the travel-sensing arrangement has a first magnetic angle sensor, and the method includes determining a first field strength in a first direction and determining a second field strength in a second direction by the first angle sensor, wherein the travel-sensing arrangement has a second magnetic angle sensor which is arranged at a predetermined distance from the first angle sensor, and the method further includes determining a first field strength in a first direction and determining a second field strength in a second direction by the second angle sensor. A travel-sensing arrangement, to a brake system having a travel-sensing arrangement, to a motor-vehicle and to a use of the travel-sensing arrangement and the method in a brake system.

Method for travel-sensing, travel-sensing arrangement and brake system

The present invention relates to a controller ( ), a cabin pressure control system ( ) and a method for controlling pressure in a cabin ( ), especially an aircraft cabin. In accordance with the invention the controller ( ) comprises a channel ( ) and a pressure differential safety function ( ). The channel ( ) calculates a first output signal ( ) for actuating an overflow valve ( ) in a closed loop control based on the pressure differential between the cabin ( ) and the atmosphere and additional critical parameters. The safety function ( ) calculates a second output signal ( ) based only on the pressure differential. The two output signals ( ) are compared, and the second output signal ( ) is selected, if said first output signal ( ) is found inaccurate. The safety function ( ) assures operation of the outflow valve ( ) even it the channel ( ) is out of function. Accordingly, the number of additional safety valves ( ) may be reduced so that the weight of the system ( ) is minimized. A manual control panel ( ) is provided for backup.
