Abstract

The invention discloses a start and stop control method for an engine of an AMT (automated mechanical transmission) parallel connection type hybrid electrical vehicle. The start and stop control method is characterized in that a detecting system detects an integral running mode, a gear state, a clutch state, the rotation speed of the engine, the rotation speed of a motor, the voltage of an energy storage system and parameters of an accelerator pedal, transmits start and stop commands for the engine, and controls start and stop of the engine; an integral vehicle controller controls an ISG (integrated starter generator) to start so as to drive the engine to start; and a flameout signal is introduced for an engine controller, and when the vehicle stops and the engine needs to stop, the integral vehicle controller transmits the flameout signal to the engine controller.

Description

technical field

[0001] The invention relates to engine control of an AMT parallel hybrid electric vehicle, in particular to an engine start-stop control method of an AMT parallel hybrid electric vehicle. Background technique

[0002] At present, the two major problems facing the sustainable development of the world's automobile industry are environmental pollution and lack of oil resources. Environmental protection and energy saving are an important development direction of automobile technology in the 21st century. At the same time, the emission regulations of various countries are becoming increasingly strict. Hybrid Electric Vehicle (HEV) is a new generation of clean energy vehicles with the characteristics of low pollution and low fuel consumption.

[0003] At present, the mild hybrid electric vehicle with the lowest manufacturing cost and the easiest mass production is the integrated engine generator / motor (ISG) technology. The motor with high transient power replaces ...
