Description

Engine rotating speed signal switching device

Technical Field

The application relates to the technical field of automobile engines, in particular to an engine rotating speed signal switching device.

Background

At present, an automobile master controller needs to control a vehicle to safely run according to a rotating speed signal of an engine, and the obtained rotating speed signal needs to be led out through a sensor. The sensors are typically mounted at the junction of the engine and transmission, with different vehicle sensors being mounted at different locations. Some sensors installed on the vehicle can be seen by opening the engine cover, and the rotation speed signal is conveniently led out. The sensors of some vehicles can be seen from the lower part only by lifting with a lifter, and the rotation speed signals are not convenient to lead out. Still some vehicle sensors are in very hidden positions, can not see from above and below, can only touch by hand, and it is very difficult to draw the rotational speed signal. For a vehicle which is easy to see, the rotating speed signal can be led out by adopting a wire breaking method temporarily, but for a vehicle which can only be touched by hands, the rotating speed signal cannot be led out by adopting the wire breaking method because no operating space exists.
