Title:
VEHICLE, DRIVE SYSTEM, AND THEIR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2007/102419
Kind Code:
A1
Abstract:
When the gear of a transmission for transmitting the torque of a motor (MG2) to
a drive shaft is subjected to a Hi-Lo change with the accelerator pedal being off
or slightly depressed, the engine is run (S150, S200) at the shifting minimum
speed (Nchg) or higher than an idling speed (Nid1). When the accelerator pedal
is depressed to set a high demand torque (Tr*), therefore, the engine can output
a high torque quickly so that a high power can be outputted more quickly to a ring
gear shaft (32a) acting as the drive shaft.
