Abstract

The invention discloses an automatic transmission gear shifting amendment control method for improving vehicle emergency braking performance. The automatic transmission gear shifting amendment control method is characterized in that when a vehicle provided with an automatic transmission is subjected to emergency braking, through gear amendment of the automatic transmission and rotating speed adjustment and the braking torque characteristic of an engine, the braking distance during vehicle emergency braking is shortened, and abrasion of a braking system is reduced.

Description

technical field

[0001] The invention relates to a control method for automatic gear shifting of a vehicle, in particular to a gear shift correction control method for an automatic transmission that improves the emergency braking performance of a vehicle. Background technique

[0002] Automatic shifting control technology is the key technology of vehicle shifting control. Automatic shifting control mainly includes single-parameter, two-parameter, three-parameter, and even four-parameter basic shift control methods to improve fuel economy and smooth shifting sex.

[0003] Drivers have different manipulation intentions in the process of driving the vehicle. When emergency braking is required in an emergency situation, the basic shift control method of automatic transmission is set according to the driving intention of the vehicle at a uniform speed, and it is impossible to take corresponding actions according to the driving intention of emergency braking. The gear shift contro...
