<P>PROBLEM TO BE SOLVED: To provide an on-board lubricant supply device that reduces a frequency at which a lubricant supply to a target portion is short. <P>SOLUTION: The on-board lubricant supply device 2 changes a control pressure PC to control a pressure of the inside of a supply oil path 21 for supplying the lubricant to the target portion of an internal combustion engine 1. The device includes: a hydraulic control mechanism 30 having, as the control pressure PC, a first control pressure PC1 and a second control pressure PC2 which is higher than the first control pressure; and a cooling water temperature sensor 54 for detecting a temperature of the internal combustion engine 1. When an output of the cooling water temperature sensor 54 is failure, an abnormal control that the control pressure PC is maintained to the second control pressure PC2 is carried out. <P>COPYRIGHT: (C)2012,JPO&INPIT |
