Document Type and Number:
WIPO Patent Application WO/2018/037718
Kind Code:
A1
Abstract:
When switching between a first operational state in which a driving wheel is driven at a first speed ratio by causing a second motor generator to act as a generator and causing a first motor generator to act as an electric motor and a second operational state in which the driving wheel is driven at a second speed ratio by causing the first motor generator to act as a generator and causing the second motor generator to act as an electric motor, a controller turns off an engine and connects the power transmission path between the first motor generator and the driving wheel and the power transmission path between the second motor generator and the driving wheel, thereby causing the first motor generator and the second motor generator to act as electric motors.
