Abstract: The energy-saving potential was estimated by simulations and drum tests for Pulse and Gliding
(PnG) driving strategies of battery electric vehicles. The relationships were investigated between several PnG
strategy parameters including oscillation distance, PnG cycle time, and average power consumption per unit
driving distance. Idling loss models were established for the motor and the powertrain. The parameters were
identified by drum tests. Three driving strategies, including the constant-speed driving strategy, the PnG strategy
with clutch, and the PnG strategy without clutch, were simulated by energy flow analysis, and then experimented
by drum test. The results show that the PnG strategy without clutch has no energy-saving potentials while the
PnG strategy with clutch can save 8.5% energy at the same average speed, compared with the constant-speed
cruise strategy at the same velocity.
