Switch Systems Theory Apply to the Energy Control of a Hybrid Electric Vehicle

Hybrid electric vehicles (HEVs) driving process including both continuous-time dynamic systems and the discrete event dynamic systems, is a typical hybrid system model. Based on a hybrid electric vehicle dynamics theory study, analyze the power demand of hybrid cars in the different operating modes, then construct a class of switched systems. Through the rational design of switching rules, make hybrid cars switch between the different power source in a more reasonable manner and improve the efficiency of engines and motors to meet the requirements under the premise of dynamic force, reduce the fuel consumption and reduce exhaust emissions.
