Abstract

The invention discloses a vehicle gear shifting method and device, and belongs to the field of vehicle driving, wherein the vehicle gear shifting method comprises the steps: obtaining a user preference degree parameter, obtaining an evaluation score, constructing a first judgment matrix by utilizing the user preference degree parameter, constructing a second judgment matrix by utilizing the evaluation score, and determining a gear to be shifted according to the first judgment matrix and the second judgment matrix. Compared with manual gear shifting, the gear shifting time is greatly shortened,compared with an existing automatic gear, the driving style of a user and the performance of an engine are fully considered, the dynamic property and the economical efficiency of the engine are improved, and simpleness and effectiveness are realized.

Description

technical field [0001] The invention relates to the field of vehicle driving, in particular to a gear shifting method and device for a vehicle. Background technique [0002] At present, vehicle shifting is mainly divided into manual shifting and automatic shifting (continuously variable transmission). Traditional manual shifting has problems such as time lag and untimely response due to reaction time. Although automatic shifting equipment avoids the driver's active shifting operation, However, the power and economy of the engine are not fully utilized, resulting in the power and economy of automatic transmission vehicles are often lower than those of manual transmission vehicles, which is not conducive to energy saving and emission reduction. [0003] For example, the Chinese invention application with the publication number CN111516694A and the publication date of 2020.08.11 discloses a gear shift control method and terminal, wherein the gear shift control method includes t...
