The invention discloses a hybrid vehicle engine ignition advance angle control method and system, a storage medium and a terminal, and belongs to the technical field of engine control. The method comprises the ignition advance angle self-learning step that the engine ignition advance angle is increased; whether knocking occurs to the engine or not is judged, and if not, the ignition advance angle of the engine continues to be increased; and otherwise, the increase of the ignition advance angle of the engine is stopped, the engine works at the knocking edge, and the current operation parameters of the engine are recorded. Operation parameters of the engine do not need to be collected and analyzed in advance, only whether the ignition advance angle enables the engine to reach the knocking edge or not is concerned, the engine works at the knocking edge all the time, then the fuel consumption potential of the engine is exerted to the maximum degree, and therefore the heat efficiency of the engine and the fuel economy are improved; and the device can adapt to different engines with different configurations and performance differences caused by external factors, and is high in reliability.
Description
technical field [0001] The present invention relates to the technical field of engine control, in particular to a method, system, storage medium and terminal for controlling ignition advance angle of a hybrid vehicle engine. Background technique [0002] Under the increasingly stringent fuel consumption regulations, hybrid electric vehicles are entering a period of rapid development just like pure electric vehicles. At present, most of the engine control methods of hybrid electric vehicles still use the traditional engine control strategy, and they still cannot achieve the purpose of improving fuel economy in terms of taking advantage of fuel consumption. [0003] Ignition advance angle is a crucial control parameter for automobile engine. The rationality and control accuracy of ignition advance angle setting directly affect the power, economy and emission of the engine. The existing technology corrects the ignition advance angle through various operating parameters of the ...
