Manual and automatic integrated shifter based on Hall induction

Abstract

The invention discloses a manual and automatic integrated shifter based on Hall induction, which relates to the field of shifter control and mainly comprises a gear shifting rod, a gear switching detection module, a manual-automatic switching detection module and a main control module. According to the invention, the Hall sensor is used, the angle of the gear shifting rod is changed during gear shifting, the magnetic flux of the Hall sensor is changed, Hall angle induction currents with different magnitudes are generated, and gears to be switched are identified according to the magnitudes of the induction currents, so that gear switching identification of a single Hall sensor is realized, the structure of the gear shifter is simplified, and interference among a plurality of Hall sensors isavoided; and during manual and automatic switching, the conduction state of the Hall switch is changed through the displacement of the gear shifting rod, so that the switching of manual and automaticmodes is realized, and meanwhile, by utilizing the Hall switch, the situation of interfering the Hall sensor does not exist during manual and automatic switching, and the false adjustment of gears isavoided.

Description

technical field [0001] The invention relates to the field of shifter control, in particular to a Hall induction-based automatic manual shifter. Background technique [0002] The car shifter is a necessary component of a modern car. The shifter cooperates with the gearbox to complete the matching of the engine speed and wheel speed through the movement of the hand, so that the car can take into account the high torque in low-speed driving and the high torque in high-speed driving. speed. With the change of social needs, the shifter itself has gradually developed from manual transmission at the beginning to automatic manual transmission today, and the shifting form has also changed from a simple mechanic's cable to today's electronic shifting form. However, the existing electronic shifting, such as the shifter based on Hall induction, often requires the help of complex electronic detection equipment, and the overall structure is complex, resulting in a large overall footprint...

Problems solved by technology

This application also uses Hall sensor to shift gears. When a dual Hall detection channel is installed at each gear position, the overall structure of the gear shifter will undoubtedly be complicated, and it will take up too much space. At the same time, a Hall sensor cannot be avoided. interference between

[0004] Another example is the Chinese patent whose publication number is CN105383413A, which discloses a circuit applied to an AMT shifter to solve the Hall interference of a non-contact switch. The problem of mutual interference between them, but it inevitably also caused the overall structure of the shifter to be complicated
