Abstract

The invention provides a method for acquiring the total weight of a hybrid power heavy-duty commercial vehicle, and mainly solves the problem that gear shifting control of an AMT (automated mechanical transmission) is affected due to the fact that an acquired total weight value of the vehicle is inaccurate. The method is an optimized and improved algorithm based on average value filtering, the total weight of the automobile can be rapidly and accurately obtained, and then gear shifting of the AMT can be accurately controlled.

Description

technical field [0001] The invention relates to the field of automatic mechanical transmission (AMT) control of a hybrid heavy-duty commercial vehicle, in particular to a method for obtaining the total weight of a hybrid heavy-duty commercial vehicle. Background technique [0002] Since the total weight of a hybrid heavy-duty commercial vehicle varies greatly when it is unloaded or fully loaded, generally between 8 tons and 50 tons, accurate acquisition of the total vehicle weight has a great influence on the control strategy of AMT shifting. For example, when the vehicle is unloaded, the total weight of the vehicle is small, and the driving force required under the same working conditions is small. Large, AMT needs to be controlled in the low gear area and high speed ratio. Therefore, automatic mechanical automatic transmission (AMT) control of hybrid heavy-duty commercial vehicles requires accurate acquisition of the gross vehicle weight value of the vehicle.
