Vehicle gear status recognition arrangement - has magnetic switches which are activated by gear shifting to control circuit which indicates gear position

摘要

In the vehicle gearbox arrangement, a movable gear (1) affects the magnetic field according to its position and activates several magnetic switches along the gearbox. The switches are activated to open and close a magnetic circuit which indicates the gear status. The magnetic switches are Reed switches or Hall devices. The gear arrangement is as follows: 5, 3, 1, R, 6, 4, 2, in new form. Signals from the magnetic circuit are sent via cable (23) to the CPU of a microcomputer. Magnetic switches (5-11) are provided for each gear. ADVANTAGE - Small overall size, and simple design.
