Title:
ハイブリッド車両用駆動装置の制御装置
Document Type and Number:
Japanese Patent JP4998098
Kind Code:
B2
Abstract:
A control device for hybrid vehicle drive apparatus which executes an internal-combustion-engine rotation control for rotating an engine output shaft under a circumstance where a consecutive travel distance LM involved in a motor drive running mode exceeds a given consecutive travel distance determining value L1. The rotation of the engine output shaft results in an effect of accelerating the lubrication of an engine. Once the engine output shaft is rotated, no component parts of the engine actually take the completely same attitudes at time before and after such rotation. This avoids the component parts of the engine from continuously remaining contact with each other in the same attitudes when encountered with running vibrations during the motor drive running mode, minimizing adverse affect on durability of the engine due to the running vibrations occurring in the motor drive running mode.
