Magnetic sensor device for the detection of the position of a motor vehicle part |
摘要 |
An electrical signal transmitter intended for use in a motor vehicle is disclosed. The signal transmitter is provided with a magnetic sensor device for the detection of various positions of a movable vehicle part. To properly recognize a variety of positions, the movable part is connected with a correspondingly movable magnetic trigger member located on a holder. The trigger member has several magnetic tracks extending in the longitudinal direction of movement of the trigger member. Each magnetic track is provided with alternating N/S pole sections to provide a coding scheme. At least one magnetic field sensitive component is associated with each magnetic track to sense fields generated from the N/S pole sections. The at least one magnetic field sensitive component then generates a signal based on the sensed magnetic fields. The signal is indicative of the position of the magnetic trigger. The magnetic field sensitive components are operable with a switching arrangement which evaluates the signal to influence a device associated with the movable part.
