Title:
MODE SWITCHING CONTROL DEVICE OF HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/087819
Kind Code:
A1
Abstract:
According to the present invention, when the requested acceleration (tG) during an EV→HEV mode switch request (S11) is large (S13), a mode switch is executed between engine startup (S14) and clutch engagement (S15-S17), and the large requested acceleration (tG) can be achieved by the torque-increasing action of a torque converter due to the torque converter being kept in a converter state during EV travel. When the requested acceleration (tG) is small (S13), a mode switch is executed between engine startup (S21) and clutch engagement (S23-S25), but the torque converter is switched from the converter state to a lockup state (S22) at the same time that clutch engagement is initiated (S22). Consequently, although the requested acceleration (tG) is small, the torque converter is no longer needlessly in a state of slipping, and worsening of engine fuel consumption can be prevented.
