Abstract

The invention discloses a reverse protection controlling method for an automatic gearbox for a vehicle, belonging to the field of automatic gearbox controlling of vehicles. The method comprises the following steps: acquiring a reverse driving signal; judging whether a reverse driving protection condition is tenable or not; sending out a reverse protection request to an engine management system if the reverse driving protection condition is tenable, and sending out a vehicle speed alarm request to an instrument panel module. By providing the reverse protection controlling method for the automatic gearbox for a vehicle, the functions of protection control and vehicle speed alarm to highest vehicle speed limit in the reverse driving process are realized, in terms of active safety and passive safety, a driver is protected from unexpected accident in the reverse driving process.

Description

A reverse gear protection control method for automobile automatic transmission technical field The invention relates to the field of automatic transmission control of automobiles, in particular to a self-protection control strategy of the automatic transmission in reverse gear. Background technique In the 1990s, the rapid development of global science and technology made new electronic technology and automatic control technology continuously adopted in automobile automatic transmissions, and high-performance automatic transmissions were continuously pushed to the market. An automatic transmission vehicle equipped with an automatic transmission does not require the driver to manually shift gears, and the vehicle will automatically select the appropriate gear according to the driving speed and traffic conditions. Automatic transmission models have been gradually recognized for their ease, comfort and all-round driving pleasure, as well as their low fuel consumption and low ...
