VACUUM SENSOR FOR BRAKE BOOSTER AND ASSOCIATED CONTROL METHOD

摘要

Vacuum sensor for brake booster and associated control method. A vacuum detector (17) for a motor vehicle brake booster vacuum chamber comprises a membrane (11) that is deformable under the effect of pressure variations in the chamber. Disposed on the membrane is an electric or electronic detection element (9) which is able to detect a threshold value of deformation of the membrane and is provided with two terminals (10a, 10b) that enable it to be connected to an electrical circuit. A resistor (15) is furthermore electrically connected between the two terminals (10a, 10b).
