Abstract

In order to further improve the fuel economy of vehicles, an efficient energy regeneration system for diesel engines is designed and constructed. An additional automatic clutch is added between the engine and the motor in a conventional ISG (Integrated Starter and Generator) system. During regenerative braking, the clutch can be disengaged and the engine braking is avoided. Control strategy is redesigned to determine the braking torque distribution and coordinate all the components. The generated electricity is increased and the fuel economy is improved. An experiment is designed to test the performance of the new energy regeneration system, and the result shows that during a regenerative braking test over 112% more electric energy can be regenerated without correcting for the fuel consumption at idle. Theoretical analysis also shows that the regenerated energy would be increased at least 63.1% for a single regenerative braking event with the new system, if we correct for the fuel consumption at idle.
