Electronic shifter and control method thereof

Abstract

The invention discloses an electronic shifter and a control method thereof. The electronic shifter includes a shift shaft, a locking gear, a motor, a worm, a photoelectric sensor for an unlocked position, a photoelectric sensor for a locked position and a circuit board, wherein: all the components located inside the electronic shifter The motor is started under control by a control circuit located on the circuit board; the worm is in transmission connection with the locking gear, so that the unlocking position photoelectric sensor block rotates synchronously with the locking gear. The electronic shifter and its control method disclosed by the present invention occupy a small space, and integrate the locking cam, gear, and optocoupler block into the locking gear. In the locked state, the force on the gear shaft is only one direction, and the There is no component force in other directions, and the structure is more concise and reliable. The reduction of the overall structure does not make the shifter function missing, and at the same time leaves sufficient space for other parts of the vehicle to be arranged.

Description

technical field [0001] The invention belongs to the technical field of electric appliances for vehicles, and in particular relates to an electronic shifter and a control method for the electronic shifter. Background technique [0002] Vehicle shifters currently on the market are mainly rod-type shifters, gear shifters, knob-type shifters, and button-type shifters. [0003] Among them, the operation of the lever-type shifter is complicated. After starting the car, step on the brake, press the unlock button and drag the handle to the desired gear, which is inconvenient for maintenance and takes up a lot of space in the vehicle. It is located between the driver and the co-driver. The bulge affects the aesthetic effect, and it is very easy to touch it when moving in the car at ordinary times, causing a lot of inconvenience.

Problems solved by technology

[0003] Among them, the operation of the lever-type shifter is complicated. After starting the car, step on the brake, press the unlock button and drag the handle to the desired gear, which is inconvenient for maintenance and takes up a lot of space in the vehicle. It is located between the driver and the co-driver. The protrusion affects the aesthetic effect, and it is easy to touch it when moving in the car, causing a lot of inconvenience

[0004] Among them, the assembly position of the gear shifter is on the side of the steering wheel, and a long operating part is extended. The wiper originally installed here needs to be moved to the left side of the steering wheel, which increases the complexity of the overall structure of the steering wheel. The part is easy to touch, and it is easy to touch when turning and turning the steering wheel, which takes up a lot of space in the vehicle and the overall layout is not neat

[0005] Among them, the installation position of the knob-type shifter and the button-type shifter is low, and the driver needs to look down when operating, which affects driving safety. Inattention can easily cause gear switching errors, and the driver needs to look down during the process of reverse parking. Only the gear button can be operated, and blind operation and continuous operation cannot be achieved. The self-locking force point of the cam mechanism generates a component force, causing the gear shaft to be subjected to tangential and normal forces at the same time, and the positioning is unreliable. Further improvement is needed.
