[0023] 3. The button can provide force value mutation (tactile feedback) and sound feedback to prompt the driver that the button function operation is effective at the same time as the button signal sensing, which is particularly suitable for noisy, complex and other harsh driving environments;

[0024] 4. The deceleration function uses a magnet and a magnetic sensor to achieve contactless recognition and transmission of the gear electrical signal;

[0025] 5. The shift controller has a reliable structure, clear shift logic, strong versatility, simple and efficient shift operation, and a very high cost performance. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the knob skeleton 36 and the knob PCBA 38 remain stationary, and the knob bullet head assembly 37 provides a force feel. The magnetic sensors at different positions on the knob PCBA 38 sense the magnetic field information of the knob magnet 35 and transmit it to the main PCBA through the PCBA harness. The shifter MCU recognizes the position signal and sends a shift position request to realize the knob shifting function; the knob function is coordinated with the bearing 33, and the rotation is clear, smooth and stable, reducing the virtual position and jamming caused by parts manufacturing and assembly errors. The shifting feel is direct and clear, and the operation is comfortable. This sensing structure is simple, stable and reliable.

[0056] like Figure 8 、 Figure 9 As shown, the button assembly 4 provides the button pressing force value and sound feedback, including a button bracket 41, a button gasket 42, a button pot 43, an N gear button 44, an AM button 45, and a button PCBA 46;

Figure 10 、 Figure 11 As shown, the end of the button bracket 41 away from the knob frame 36 is provided with an N button assembly cavity 411 and an AM button assembly cavity 412 in parallel;

[0058] The key pad 42 is provided at the other end of the key bracket 41;

[0059] The key pot 43 is assembled between the key bracket 41 and the key gasket 42 and fixed on the knob lower shell 31;

[0060] The N-gear button 44 is assembled on the button bracket 41 via the N-gear button skeleton 441 and extends from the open end of the knob cover 22.

The N-gear button skeleton 441 is assembled in the N-gear button assembly cavity 411 of the button bracket 41 and can be guided therein.

[0061] When the N-gear button 44 is pressed, the N-gear button spring 442 provides continuous linear force feedback, and then the N-gear button frame 441 presses on the pot piece 43, which provides a sudden force change and sound feedback. At this time, the magnetic sensor on the button PCBA46 senses the magnetic field information of the button magnet 443 on the N-gear button frame 441. This signal is transmitted to the main PCBA7 through the knob PCBA38 connected to the button PCBA46, and the main PCBA7 determines and recognizes the gear signal;

[0062] The AM button 45 and the N button 44 operate on the same principle and are assembled to the button bracket 41 via an AM button skeleton 451. The AM button 45 is clipped and fixed to the AM button skeleton 451. The AM button skeleton 451 is equipped with an AM button spring 452 and an AM button sensing magnet 453.

[0068] One end of the second roller assembly 54 is assembled in the roller assembly mounting hole 512 of the dial button frame 51, and the other end of the roller is pressed against the dial button groove 53;

[0069] By moving the knob upper cover 32 and the knob lower shell 31 up and down, the knob skeleton 36, the knob PCBA38, the knob skeleton 52, and the knob guide pin 51 move up and down. The second roller assembly 54 provides a force feel. The knob guide pin 51 presses the micro-touch switch on the knob PCBA38 while the knob moves up and down, thereby realizing the judgment and recognition of the gear signal.

[0070] The gear sensing magnet 6 is located in the housing 1 and is mounted on the side of the joystick 23 close to the main PCBA 7;

[0071] The main PCBA 7 is mounted on the lower housing 14 of the housing 1 and has evenly arranged magnetic sensors 71 . The magnetic sensors 71 are located below the induction magnets 6 .

[0072] The knob of the present invention can rotate around the knob frame 36 and rotate up and down around the axis. The operating axes of the knob and the dial are arranged in a cross. The handle integrates the functions of the knob and the dial. The structural space is small and the gear shifting operation is clear and unambiguous.

[0073] When the shift lever is moved forward or backward, the roller assembly provides a sense of force, and the magnet moves with the joystick 23. The magnetic sensor on the main PCBA senses the magnet's magnetic field, and the shifter MCU recognizes the position signal and sends a shift position request, enabling slow shifting. The signal transmission between the magnet and the magnetic sensor occurs without mechanical contact, reducing gear position sensing deviations caused by manufacturing and assembly tolerances and ensuring stable gear position sensing.

[0074] like Figure 15 As shown, in another embodiment, the rotating shafts 361a in the knob skeleton 36a are arranged in two groups perpendicular to each other, which can realize the operation of moving the knob forward and backward, left and right, and realize more functions.
