lel hybrid is considered to be most
advantageous for the truck drive mode,
showing the best balance among fuel
saving, cost and weight.
Within the parallel hybrid system,
several configurations are available,
depending on the positioning of the
electric machine.
“We consider the parallel hybrid sys-
tem with the electric motor positioned
between the clutch and the transmission
as the best option for most truck applica-
tions,” said Akikawa. “The clutch can be
disengaged during deceleration, with a
higher recuperation capability compared
to systems with the electric motor cou-
pled to the combustion engine, before
the clutch and the transmission.”
According to Mitsubishi Fuso, another
configuration for on-highway operation is
for the electric motor to directly drive the
rear axle, thus avoiding the tandem shaft
between the two rear axles.
For example, the structure of the light-
duty Canter Eco hybrid truck is a
parallel hybrid sys-
tem with a slim 35
k W brushless per-
manent-magnet synchronous electric
motor/generator by Mitsubishi Heavy
Industries, positioned between the
clutch and transmission, and 346 V Li-
ion batteries produced by Hitachi
Vehicle Energy.
The light-duty Canter Eco hybrid truck by Mitsubishi Fuso features a parallel hybrid system
with a 35 kW electric motor and Li-ion batteries. The diesel engine is a 96 kW Canter turbocharged unit.
