Description

Technical Field

[0002] In the transmission, the gear switch is an important control element, which is related to the safe operation of the whole vehicle. Its most basic feature is the on-off function. The existing gear switches can be divided into contact mechanical pressure switches and non-contact electronic switches. When a mechanical pressure switch is under the action of an external force, the push rod moves linearly within a certain range, pushing the contact to close (or open). Once the external force disappears, its reaction spring automatically resets to keep the contact in its original state. The non-contact electronic switch uses a programmable Hall chip to detect changes in the magnetic field and trigger its internal circuit to turn on or off.

[0003] There are many kinds of gear switches on the transmission. Professional gear switch detection equipment is often large in size and inconvenient to move due to its comprehensive functions. It also requires on-site power supply and is not suitable for on-site fault diagnosis of the whole vehicle and rapid judgment of the basic on-off function of the switch.
