Embodiment Construction

[0022] see figure 1 , the automotive electronic knob shifter of the present invention comprises:

[0023] - Knob 10, at least having a rotary function. Different rotation positions of the knob 10 represent different gears of the vehicle, and these gears at least include P gear, R gear, N gear and D gear, and some vehicles also have S gear, L gear, etc. The knob 10 is used to represent all gears of the vehicle. stalls.

[0024] -The microprocessor 20 detects the position of the knob 10 and sends a pulse signal to drive the motor 40 to rotate to one of the first motor drive module 31, or the second motor drive module 32, or the third motor drive module 33; the microprocessor The microprocessor 20 also receives the feedback pulse signal and the feedback rotation signal from the motor position feedback module 60 ; the microprocessor 20 stores the sent and / or received data in the non-volatile memory 70 .

[0025] - The first motor drive module 31 receives the pulse signal sent b...

Abstract

The invention discloses an automobile electronic knob gear shift, which comprises a knob (10), a microprocessor (20), a first motor driving module (31), a second motor driving module (32), a third motor driving module (33), a motor (40), a reduction gearbox (50), a motor position feedback module (60), a nonvolatile memory (70) and a power supply (80), wherein three independent physical channels are formed between the microprocessor (20) and the three motor driving modules for failover; and the motor position feedback module (60) has two detection means of pulse monitoring and rotation angle detection. The gear shift completely replaces a shifter and a gear stick in the conventional vehicle and has the advantages of simple structure and convenience of implementation; moreover, the mechanical friction of the gear stick is avoided, and the use space in a carriage is enlarged.

Description

technical field [0001] The present invention relates to a kind of automobile gearbox (Transmission, gearbox) structure, in particular to a kind of gear stick (gearstick, gearstick, gear lever, selection lever, shift stick, gear shifter, also known as shift lever) for automobile gearbox , selector lever) improved structure. Background technique [0002] Whether it is a manual transmission (Manual Transmission, MT) or an automatic transmission (Automatic Transmission, AT) vehicle, it has at least the following gear modes: P (Park, parking gear), R (Reverse, reverse gear), N (Neutral, neutral gear), D (Drive, forward gear). [0003] All have gear lever in the gearbox of existing vehicle, and one end of gear lever is connected with the gear shifter that is positioned at the compartment, and the other end is connected with shift valve. The driver changes the gear mode of the vehicle by manipulating the gear shifter and then driving the gear lever. This gear shifting method has ...
