Abstract

The invention provides a gear driving acquisition system and method. The system comprises a plurality of Hall switches, a plug connector and an MCU. The plurality of Hall switches detect the intensityof the magnetic field generated by a gear rotating switch, output a first voltage signal when the magnetic field intensity is smaller than a preset first threshold value or rises from the first threshold value to a preset second threshold value, and output a second voltage signal when the magnetic field intensity is greater than the preset second threshold value or drops from the second thresholdvalue to the first threshold value. The plug connector comprises a plurality of pins, wherein each pin is connected with the output end of one Hall switch, when the Hall switches output a first voltage signal, the pins output the first voltage signal, and when the Hall switches output a second voltage signal, the pins output the second voltage signal. The MCU is connected with the pins of the plug connector, detects the voltage signal of each pin, and determines the gear of the gear rotating switch corresponding to the first pin when detecting that the second voltage signal exists in the first pin. Therefore, the current gear can be simply determined through the MCU.

Description

technical field

[0001] The invention relates to the technical field of electronic circuits, in particular to a gear drive acquisition system and method. Background technique

[0002] With the rapid development of the automobile industry, the requirements for the acquisition and control of automobile gear positions are getting higher and higher, especially in the field of low-speed modified vehicles, simple, accurate and stable gear acquisition is very necessary.

[0003] The existing gear position signal acquisition circuit is usually integrated in the auxiliary control unit of the car, which cannot be easily removed separately for modification of the car gear position.

[0004] In the prior art, the design and operation of the gear drive acquisition system is relatively complicated, therefore, a simple and easy-to-operate gear drive acquisition system is urgently needed. Contents of the invention

[0005] The purpose of the embodiments of the present invention is to prov...
