A new parallel-type hybrid electric-vehicle
Applied Energy, 2004This new system promises an internal-combustion engine that always maintains optimal operating conditions. The system comprises two parts: (1) an internal-combustion power-distribution device and (2) an integrated design involving the engine and electronic motor. The internal-combustion power-distribution device provides an engine capable of constantly

Hierarchical Model Predictive Control for Parallel Hybrid Electrical Vehicles
Asian Journal of Control, 2018AbstractOne purpose of the control strategy for a parallel hybrid electric vehicle (PHEV) is to control the state of charge (SOC) of the battery to achieve a maximum powertrain efficiency. Because of the nonlinearity of the powertrain, the control strategy should implement nonlinear optimization in real time.

Virtual serial strategy for parallel hybrid electric vehicles
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2014A new strategy to control the power split in hybrid electric vehicles is presented. The strategy is proposed for a parallel hybrid vehicle where the internal-combustion engine and the electric machine are coupled by a planetary gear system. This low computational burden strategy is designed to operate the internal-combustion engine at the maximum ...
