Title:
DRIVE CONTROLLER OF ELECTRIC VEHICLE AND ITS CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2007/049703
Kind Code:
A1
Abstract:
Power balance is achieved between first and second motors and fuel efficiency
of an electric vehicle is improved. The drive controller of an electric vehicle
comprising first and second motors, a differential gear having first through
third rotary elements where the first rotary element is coupled with the first
motor, the second rotary element is coupled with the second motor through a transmission
shaft (15), and the third rotary element is coupled with an engine (11), a transmission
(18), a motor control means for controlling the rotational speed of the first
motor according to speed change by the transmission (18), and a power regulation
means for regulating power consumption of the first and second motors. Since
power balance can be achieved between the first and second motors, power supply
from a battery to the first and second motors is not required and fuel efficiency
of an electric vehicle is improved.
