Control method for intelligent electronic control unit of hybrid electric vehicle engine

Abstract

The invention discloses a control method for an intelligent electronic control unit of a hybrid electric vehicle engine. The method belongs to the technical field of engine control. The control method for the intelligent electronic control unit of the engine comprises the steps that power-on initialization is carried out, and information is collected and interacted; a response module acts, and emergency processing is implemented; a cooperation module acts, and expected torque and an expected rotation speed are decided; and a local planning module acts, and corresponding torque and a corresponding rotation speed are obtained. The method disclosed by the invention is characterized in that an engine intelligent body kernel is disposed based on an original ECU of the engine; the method aims to grant an engine intelligent body with a capability of interaction and cooperation and enhance intelligence of the engine intelligent body; and optimized solution and calculation are carried out to the demanded torque and the demanded rotation speed of the engine by an internal control algorithm, so that performance of the engine is optimized.

Description

technical field [0001] The invention relates to the technical field of engine control, in particular to a control method for an intelligent electronic control unit of a hybrid vehicle engine. Background technique [0002] By the end of 2015, the global car population reached about 1.12 billion. The huge number of cars has further exacerbated the energy crisis and environmental pollution, making energy saving and emission reduction popular among the people. New energy vehicles have become a research and development hotspot in the automotive industry today. Hybrid Electric Vehicle (HEV) is a transitional model between traditional vehicles and pure electric vehicles. It combines the advantages of both. The technology platform is relatively complete and mature, and it is the first choice for the development of new energy vehicles. preferred. A hybrid electric vehicle has two sets of power systems, and the development of its powertrain integrated control system is one of the ke...
