Abstract
In this work, a supervisory control strategy is pro-
posed for parallel hybrid electric vehicles (HEVs). The control
strategy is based on the equivalent consumption minimization
strategy (ECMS) but it also considers the power consumed
by the engine cooling system to optimize the overall fuel
economy of the vehicle. To verify its effectiveness, the proposed
cooling-sensitive ECMS is implemented on a through-the-road
(TTR) HEV, after the mathematical model of the TTR HEV is
developed based on power flows, and engine thermal dynamics
is also included. Simulations are performed with different drive
cycles, and the results show that the cooling-sensitive ECMS is
able to improve the fuel economy by 2.7% compared to the
baseline ECMS. Furthermore, it is shown that cooling-sensitive
ECMS operates in a charge-sustaining manner provided that
the equivalence factors are optimally selected.
