Title:
POWER OUTPUT DEVICE, HYBRID AUTOMOBILE HAVING THE DEVICE, CONTROL METHOD FOR THE POWER OUTPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/069019
Kind Code:
A1
Abstract:
In a hybrid automobile (20), an engine (22), motors (MG1 and MG2) and a transmission (60)
are so controlled that a power based on a demanded torque (Tr*) may be outputted to
a drive shaft (67), while being accompanied by both an engine speed adjusting operation
to make the speed (Ne) of the engine (22) identical to a shift speed (= γt/k·V)
based on an upper side shift gear ratio (γtu(n)), i.e., an executing shift
gear ratio (γt) and a shift from an n-th gear ratio state to a (n+1)-th gear
ratio state, when the demanded gear ratio (γr) or the demanded value of
the gear ratio between the engine (22) and the drive shaft (67) becomes the lower
limit gear ratio (γlim(n)) or less or an n-th shift gear ratio (γt(n))
or less while the n-th gear ratio state is in the midst of being set by the transmission
(60).
