Four-driven strong-hybrid automobile AMT (automated mechanical transmission) coordinated control method and system thereof

Abstract

The invention discloses a four-driven strong-hybrid automobile AMT (automated mechanical transmission) coordinated control method and a system thereof, belonging to the field of hybrid automobile control. Driving information is acquired by a whole automobile controller which is also responsible for managing and distributing the torque needed by the whole automobile. The method comprises the following steps of: determining the whole automobile driving mode, and selecting the whole automobile driving mode adaptive to the driving information; sending instruction information to an AMT controller according to the whole automobile driving mode, and executing the instruction control of the whole automobile controller by the AMT controller; and carrying out coordinated control on all driving motor controllers by the whole automobile controller according to the execution condition of the AMT controller so as to meet the requirement for smooth shifting of a driver for driving. In the AMT coordinated control method, by coordinated control of the whole automobile controller to the AMT controller, the shifting smoothness of an AMT is effectively improved, so that the shifting becomes faster and more comfortable; and simultaneously a rear-driven pure-electric driving mode is utilized for preventing an AMT system from working at the stages of starting and low speed, so that the automobile driving is more economic.

Description

technical field

[0001] The present invention relates to the field of vehicle control of hybrid electric vehicles, in particular to a coordinated control method for an AMT (Automated Mechanical Transmission, electronically controlled mechanical automatic transmission) of a four-wheel-drive strong hybrid vehicle, the coordinated control of the strong hybrid power system control and the AMT system, improving And improve the shift time and shift shock of the AMT system, so that it can be effectively matched with the strong hybrid system. Background technique

[0002] Hybrid electric vehicles have both the advantages of pure electric vehicles and conventional power vehicles. Compared with conventional power vehicles, they have excellent power performance, fuel economy and emission performance. The company has increased the research and development of hybrid electric vehicles, and has received extensive attention from users and the market.
