Plug in Hybrid Electric Vehicle Control Strategies
Researchers at the University of Texas at Dallas are currently building a test bed to simulate a plug-in hybrid electric vehicle (PHEV) under various control strategies to maximize efficiency and reduce fuel consumption.
The PHEV is a new technology that requires advanced control methods. PHEVs combine electric motors and an internal combustion engine to improve fuel economy and, in certain cases, run part of the time as an electric vehicle using electricity provided by the electric grid as the only fuel source. Precise control of engine speed, engine torque, electricity flow to and from the battery and other energy storage devices, electric motor speed, electric motor torque, generator torque and others variables are all required to maximize efficiency and performance.
Currently being built is a unit that will be able to model both series and parallel PHEVs. This unit will be able to accurately sense and control all of the variables listed above in order to test various control strategies under a wide range of driving conditions. This test bed will be instrumental in improving the efficiency of the PHEV.
