Title:
CONTROLLER OF TRANSMISSION OF VARIABLE-CAPACITY PUMP MOTOR TYPE
Document Type and Number:
WIPO Patent Application WO/2008/075758
Kind Code:
A1
Abstract:
Gear change of a transmission using variable-capacity pump motor with no increase
of the rotational speed of the power source is possible by judging the fixed gear
which is set by locking one of the pump motors. The controller comprises judging
means (step S2) for judging whether the extrusion capacity of one of the pump motor
is zero or not and transmission control means (step S3) for carrying out control
to operate one of the synchronizers so that one of the transmission mechanisms
for transmitting the power from the power source to the output shaft is brought
into a power transmission disabled state from a power transmission enabled state
when the judging means has judged that the extrusion capacity of one of the pump
motors for transmitting the power from the power source to the output shaft through
the one of the transmission mechanisms is zero.
