Abstract
(EN)

The drive control of the invention is applicable to a motor vehicle equipped with an engine, a first motor, a second motor, a planetary gear mechanism, a transmission, and an accumulator unit. In the motor vehicle, a sun gear, a carrier, and a ring gear of the planetary gear mechanism are respectively connected to the first motor, the engine, and a driveshaft, and the second motor is connected to the drive-shaft via the transmission. In response to a decrease in torque transmitted from the second motor to the driveshaft (that is, upon identification of a flag F1 equal to ‘1’ representing a torque phase) during an upshift operation of the transmission in the state of output of a positive torque from the second motor, the drive control of the invention lowers a target rotation speed Ne* of the engine to decrease a torque command Tm1*=(negative torque) of the first motor. This increases a direct torque Ter directly transmitted from the engine to the driveshaft by the first motor. The drive control then increases a torque command Tm2* of the second motor by a predetermined positive torque Tup and causes the second motor to consume at least part of electric power generated by the first motor under the condition of the increasing direct torque Ter. Such control effectively suppresses a decrease in torque applied to the driveshaft, while preventing excessive input of electric power into the accumulator unit.
