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

Embodiment 1

[0061] In order to solve the above problems and optimize the overall structure of the shifter based on Hall induction without interfering with each other, the present invention proposes a manual shifter based on Hall induction, such as figure 1 As shown, it includes the shift lever, the gear switching detection module, the manual automatic switching detection module and the main control module, among which:

[0062] The shift lever is used to switch between manual gear and automatic gear according to the position of the shift lever, and to switch gears according to the forward and backward rotation of the shift lever;

[0063] The automatic manual switching detection module is used to generate the first Hall switch signal to control the gearbox to enter the manual mode when the shift lever is switched to the first position, and is used to generate the second Hall switch signal when the shift lever is switched to the second position. The Hall switch signal controls the transmis...

Embodiment 2

[0103] In order to better illustrate the technical points of the present invention, the present embodiment analyzes the present invention through a practical operation, such as Figure 1 to Figure 12 Shown:

[0104] When the car's start key is inserted but the engine is not started, the vehicle is only powered by the car battery, and through the overcurrent suppression and battery voltage detection circuit (such as Figure 13 As shown, the auxiliary circuit led by the first pin of the main control module), the KL30 terminal introduces the power supply signal of the car battery, and the signal passes through the seventh and eleventh capacitors, the first bidirectional voltage regulator diode, the first diode, EC1 , the sixth inductance, the fifth, sixth and eighth capacitors are transmitted to the first pin (U2.1) of the main control chip, and the KL30 terminal is connected to the first interface of the CAN communication connector.

[0105] And when the engine is started, the ...

Abstract

The invention discloses a Hall sensor-based automatic manual shifter, relates to the field of shifter control, and mainly includes a shift lever, a gear switching detection module, a manual manual switching detection module and a main control module. According to the change of the magnetic flux of the Hall sensor caused by the change of the angle of the shift lever when the gear is shifted through the Hall sensor, different sizes of Hall angle induced currents are generated, and the gear to be switched is identified according to the size of the induced current, thereby realizing The gear switching recognition of a single Hall sensor simplifies the structure of the shifter and avoids the interference between multiple Hall sensors; while in manual and automatic switching, the displacement of the gear lever changes the conduction of the Hall switch. At the same time, using the Hall switch, there will be no interference with the Hall sensor when switching between manual and automatic, avoiding misadjustment of gears.

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...
