Problems solved by technology

[0004] During the research and practice of the prior art, the inventor of the present application found that for some 6AT+ (6AutoTransmission+, 6-speed automatic transmission) electronic shifter models, when the forward gear or the reverse gear is put into the parking gear, and then the When the parking gear is out (such as P-R / P-N / P-D), there will be a shift shock during the process, which will affect the driver's driving experience

Abstract

The present invention relates to a gear position control method, device and medium. The method includes: judging whether a first parking gear switching control instruction for switching the gear of an automatic transmission to a parking gear is received; When the gear switching control command is used, the gear position of the automatic transmission is controlled to be switched to neutral gear; it is judged whether the ratio of the input shaft speed of the automatic transmission of the current vehicle to the engine speed of the engine of the current vehicle is greater than a preset value; when the ratio When it is greater than the preset value, the gear position of the automatic transmission is controlled to be switched from neutral gear to parking gear. The implementation of the present invention can avoid the shifting impact caused by the forward gear or the reverse gear being shifted into the parking gear for some 6AT+electronic shifter models, and then the parking gear is shifted out.

Description

technical field [0001] The invention relates to the technical field of automatic transmissions, in particular to a gear control method, device and medium. Background technique [0002] The automatic transmission automatically moves up and down gears according to factors such as vehicle speed, engine speed, power load, etc., without the need for the driver to operate the clutch to shift gears, so it is very convenient to use. Especially when driving on urban roads with relatively congested traffic, the automatic transmission shows very good convenience. [0003] In the prior art, when parking is required, the driver will switch the gear position of the automatic transmission from a forward gear (D gear) or a reverse gear (R gear) to a parking gear (P gear). When the gear of the automatic transmission is in the forward gear or the reverse gear, the engine torque is output to the drive shaft, and the vehicle can move forward or backward under the driving force of the drive sha...
