Study on the Engine Start/Stop Control Strategy of Hybrid Vehicles

Abstract:

The hybrid vehicle is currently one of the research focuses of automotive industry. The mode of ‘engine start/stop strategy’ has become a crucial part in (hybrid) vehicle control strategy. In this paper, both home and abroad researches of the ‘engine start/stop control strategy’ were summed up. From automotive engineering perspective, several aspects were in-depth analyzed and discussed, including the engine providing control energy or power resources, substitutability of energy and the negative problems brought by starting/stopping the engine. According to economy and overall loss, the objective function of optimization of the strategy was proposed. For solving the related engineering application problems caused by using the engine start/stop strategy on hybrid vehicles, the appropriate additional solutions were given from three aspects such as adding power source, controlling and switching clutch program of power source, and coupling and connection of the engine and auxiliary energy, providing an important reference for related study.
