    • Under a switchover operation of an EGR valve from OFF to ON or from ON to OFF, the control procedure of the invention keeps an engine power demand Pe*, which is to be output from an engine and is set corresponding to a torque demand Tr* to be output to a drive shaft, unchanged to a previous level (Previous Pe*) set immediately before the switchover operation of the EGR valve (step S120). A torque command Tm2* of a motor MG2 is set to ensure output of the torque demand Tr* to the drive shaft (step S126). The engine and motors MG1 and MG2 are then driven and controlled with preset target values and torque commands. Such control desirably prevents a variation in load of the engine simultaneous with the switchover operation of the EGR valve and accordingly ensures favorable emission control performance, while attaining output of the torque demand Tr* to the drive shaft.
    • 在EGR阀从OFF到ON或从ON到OFF的切换操作下,本发明的控制程序保持了从发动机输出并根据转矩要求Tr *设定的发动机功率要求Pe * 输出到在EGR阀的切换操作之前立即设定的上一级(先前Pe *)的驱动轴(步骤S120)。 马达MG2的转矩指令Tm2 *被设定为确保向驱动轴输出转矩要求Tr *(步骤S126)。 然后用预设的目标值和扭矩指令来驱动和控制发动机和马达MG 1和MG 2。 这样的控制期望与EGR阀的切换操作同时防止发动机的负载变化,并且在获得对驱动轴的转矩要求Tr *的输出的同时确保良好的排放控制性能。
