Tempo [s]
Accumulators SOC are
empty. Air system is
supplied by the engine
power.
The vehicle speed is kept
approximately constant
by the hybrid system.
Accumulators and
reservoir are been
charged. Air system is
supplied by the
hydrostatic unit power
REGENERATIVE
MODE 2
Accumulat
ors SOC
are empty.
Air system
is supplied
by the
engine
power.
Accumulators SOC are
full. Air system can be
supplied by the
accumulators power when
the pneumatic pressure is
low.
CHARGING MODE 1REGENERATIVE
MODE 1CHARGING MODE 2
CHARGING
MODE 1
Vehicle is decelerated
until its standstill.
Accumulators are
charged firstly to
increase hydraulic
pressure and reduce
the braking distance
