HYBRID VEHICLE MODE SWITCH CONTROL DEVICE

摘要

An engine is started and a clutch (CL) is engaged in accordance with an EV→HEV mode switch request (t2). Engine rotation is input to a transmission when the starting of the engine is completed (t3), thus enabling the calculation of an actual transmission ratio (Ip). When the actual transmission ratio (Ip) differs from a target transmission ratio (tIp), a lack of drive power corresponding to a transmission ratio deviation (&Dgr;Ip) between the transmission ratios is caused relative to a request, causing the driver to feel a sense of discomfort. A motor torque (Tm) is corrected by being increased by a motor torque correction amount (&Dgr;Tm) required for eliminating the lack of drive power, or an engine torque (Te) is corrected by being increased by an engine torque correction amount (&Dgr;Te) required for eliminating the lack of drive power. In this way, the lack of drive power due to the transmission ratio deviation (&Dgr;Ip) and the driver's sense of discomfort can be eliminated.
