Abstract
This paper discusses an electric generation control method applying a model predictive control (MPC) for a series hybrid vehicle (HEV). In the MPC, an optimal control method minimizing an evaluation function including both energy and drive-feeling was utilized. A function dependent on the vehicle speed was introduced into the evaluation function as a target drive-feeling. By describing the engine power model as linear differential equations, the optimal trajectory over the prediction horizon was derived analytically. A vehicle control module (VCM) installed the MPC with the drive-feeling function controlled the generation system in the HEV. It was shown that the performance of the new electric generation control became excellent through driving tests.
