Design of a power-split hybrid electric vehicle control system utilizing a rule-based controller and an equivalent consumption minimization strategy

The paper proposes a power-split hybrid electric vehicle control strategy that combines a rule-based controller, including a state-of-charge controller and engine start–stop logic, with a precisely formulated equivalent consumption minimization strategy. A one-dimensional directional search-based instantaneous equivalent consumption minimization strategy optimization and a two-dimensional directional search-based instantaneous equivalent consumption minimization strategy optimization are used to find optimal powertrain points in high-efficiency engine map regions that are previously determined by an offline optimization approach. The simulation results confirm that the rule-based controller performance can be significantly improved when extended with the proposed equivalent consumption minimization strategy formulation, without requiring an adaptive empirical penalty factor to satisfy the state-of-charge sustainability condition. The proposed rule-based + equivalent consumption minimization strategy control strategies were verified against a dynamic-programming-based optimization benchmark for different certification driving cycles.

Design and Implementation of Hybrid Electric Vehicle Control System CAN Communication

Based on the vehicle CAN bus technology, with features of Hybrid Electric Vehicle (HEV) control network be concerned, CAN bus protocols of application layer suitable for HEV are developed in the paper. And control network is built based on multi-master CAN distributed control technology. Through CAN controller programming of DSP, supported by the corresponding external drive circuit, the motor controller nodes is connected with the vehicle CAN network. Finally the CAN Bus communication of HEV energy assembly control system is designed and realized. Experimental result indicates that the system works well with stable signal and strong anti-jamming ability, and the communication with HEV CAN bus is realized successfully.

Development of Hybrid Electric Vehicle Control System Based on V-Cycle

The development of control system for hybrid electric vehicle (HEV) is a complex project and should be guided using an efficient development procedure. In this paper, the V-cycle development approach has been applied to the development of HEV control system. The five steps of V-cycle including function design, rapid control prototyping (RCP), production code generation, hardware-in-loop simulation (HIL) and calibration have been analyzed in detail and realized by using tools such as MATLAB/Simulink/Stateflow, dSPACE MicroAutoBox, MATLAB/Embedded Target for Motorola MPC555 and Vector CANape. The results of the investigation show that this method can help to shorten the development period, ease the labor of experiments and reduce the development cost.
