Research on optimal control of hybrid vehicle torque distribution

The main reason of hybrid vehicle fuel saving is superior to the ordinary vehicles is through motor support to optimize the operation of the engine, in order to achieve the purpose of the fuel efficiency and reduce emissions. The traditional optimization method that the baseline is optimization of engine operating point, line, and optimize the operating range to make the engine run in optimal working range. In recent years, the principle of minimum value to the whole power system has a wide range of applications. The optimization was studied for the hybrid dual-clutch system; verify the results of optimization in the bench test. Relatively regular vehicles, hybrid systems using baseline control strategy the oil-saving rate is 16.7%, the minimum principle strategy is 21.7%.
