Title:
DRIVING DEVICE FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JP3835158
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To circulate and feed lubricating and cooling liquid to each driving unit according to the state of a plurality of drivers.
SOLUTION: In lubricating and cooling a plurality of driving units such as a motor and a generator, or a clutch, a CVT, and the like of an engine rotating shaft system, a motor rotating shaft system or a driving shaft system, when motor temperature Tm and generator temperature Tg are high, oil is circulated and fed preferentially to the motor and generator (S106, S112), and when any one of engine speed Ne, motor shaft rotating speed Nm and driving shaft rotating speed Nd is high, oil is circulated and fed preferentially to a bearing of the corresponding rotating shaft system (S116). When oil temperature To is low, oil is circulated and fed preferentially to the bearing of each rotating shaft system (S118). As a result, each driving unit can be more appropriately lubricated and cooled according to the state of a plurality of drivers.
