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 driveshaft 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.

本发明的驱动控制可应用于装有发动机、第一电机、第二电机、行星齿轮机构、变速器和蓄电单元的车辆。行星齿轮机构的太阳齿轮、行星架和齿圈分别与第一电机、发动机和驱动轴相连,第二电机经变速器与驱动轴相连。当在从第二电机输出正转矩的情况下在变速器换高速档期间第二电机传给驱动轴的转矩减小(即识别到表示转矩阶段的标记F1等于1)时,减小发动机目标转速Ne*,以减小第一电机的要求转矩Tm1*(负转矩)。从而借助第一电机增大从发动机直接传递给驱动轴的直接转矩Ter。然后使第二电机的要求转矩Tm2*增大预定正转矩Tup,并在增大直接转矩Ter的情况下使第二电机消耗由第一电机产生的至少部分电力。该控制有效抑制施加给驱动轴的转矩的减小,并防止电力过度输入到蓄电单元。
