The invention discloses an engine intelligent electronic control unit for a hybrid electric vehicle and belongs to the technical field of engine control. The engine intelligent electronic control unit comprises an original engine ECU and an engine intelligent body kernel. The original engine ECU comprises a sensor module, an effector module and a functional unit module. The engine intelligent body kernel comprises a reaction module, a database, a communication module, a collaboration module and a local planning module. The original engine ECU and all the modules in an engine intelligent body are matched with one another. The sensor module is directly connected with the reaction module. The functional unit module comprises a flameout performance function and a rotation speed and torque control function and is used for controlling an engine to output corresponding power. The engine intelligent electronic control unit for the hybrid electric vehicle aims at giving the interactive collaboration capacity to the engine intelligent body and improving the intelligence of the engine intelligent body at the same time, and the required torque and the required rotation speed of the engine are optimally solved and calculated through the internal control algorithm, so that the performance of the engine is optimized.
