车辆用驱动装置
摘要：
本发明提供一种车辆用驱动装置，驱动装置(10)具有：第一变速机构(30)，其能够以第一输入轴(27)接受来自内燃机输出轴(8)的机械动力；第二机构(40)，其能够以第二输入轴(38)接受来自内燃机输出轴(8)和电机(50)的机械动力；以及第一离合器(21)，其能够使内燃机输出轴(8)与第一输入轴(27)接合。ECU(100)，在进行内燃机(5)的起转时，对第一变速机构(30)和第二变速机构(40)的变速档进行选择，并且将第一离合器(21)设为接合状态，使得将第二输入轴(28)接受到的机械动力变速而传递至第一输入轴(27)。通过第二变速机构(40)和第一变速机构(30)进行变速使转矩增大，使来自电机(50)的机械动力经由第一离合器(21)传递至内燃机输出轴(8)。
摘要（英）：

A driving device (10) has a first speed change mechanism (30) receiving the mechanical power from an engine output shaft (8) by the first input shaft (27), a second speed change mechanism (40) receiving the mechanical power from the engine output shaft (8) and a motor (50) by the second input shaft (28), and a first clutch (21) which can connect the engine output shaft (8) and the first input shaft (27). When cranking an internal combustion engine (5), an ECU (100) selects the shifting step of the first speed change mechanism (30) and the second speed change mechanism (40) such that a mechanical power received by the second input shaft (28) is transmitted to the first input shaft (27) while being decelerated, and brings the first clutch (21) into connection state. A mechanical power from the motor (50) is decelerated by the second speed change mechanism (40) and the first speed change mechanism (30) in order to increase the torque and then transmitted to the engine output shaft (8) through the first clutch (21).
