Abstract:
An oil supply control device for an engine includes: a hydraulic controller which outputs a control value to an adjusting device to cause a detected hydraulic pressure detected by a hydraulic pressure sensor to coincide with a predetermined hydraulic pressure value; a determination portion which compares an output control value output from the hydraulic controller to the adjusting device when the detected hydraulic pressure coincides with the predetermined hydraulic pressure value and a control value stored in a memory, to determine whether or not a difference between the output control value and the stored control value lies within a predetermined allowable range; and a device controller which allows activation of a hydraulic actuating device when an oil temperature is not lower than a first temperature in a case where the difference lies within the allowable range, inhibits activation of the hydraulic actuating device when the oil temperature is lower than a second temperature higher than the first temperature in a case where the difference does not lie within the allowable range, and allows activation of the hydraulic actuating device when the oil temperature is not lower than the second temperature in a case where the difference does not lie within the allowable range.

Claim (Index 1):
An oil supply control device for an engine, comprising:\n an oil pump of which an oil discharge amount is variable; a hydraulic actuating device which is activated in response to a pressure of oil supplied from the oil pump; a hydraulic pressure sensor which is disposed in an oil supply passage connecting the oil pump and the hydraulic actuating device, and detects a hydraulic pressure; an oil temperature sensor which detects a temperature of oil circulating within the engine by the oil pump; an adjusting device which adjusts the oil discharge amount from the oil pump according to an input control value to adjust the hydraulic pressure; a memory which stores the control value which is determined in advance for the each oil temperature depending on an operating state of the engine at a predetermined hydraulic pressure value; a hydraulic controller which outputs the control value to the adjusting device to cause a detected hydraulic pressure detected by the hydraulic pressure sensor to coincide with the predetermined hydraulic pressure value; a determination portion which compares an output control value output from the hydraulic controller to the adjusting device when the detected hydraulic pressure coincides with the predetermined hydraulic pressure value and the control value stored in the memory, to determine whether or not a difference between the output control value and the control value stored in the memory lies within a predetermined allowable range; and a device controller which allows activation of the hydraulic actuating device when the oil temperature is not lower than a first temperature in a case where the difference lies within the allowable range, inhibits activation of the hydraulic actuating device when the oil temperature is lower than a second temperature higher than the first temperature in a case where the difference does not lie within the allowable range, and allows activation of the hydraulic actuating device when the oil temperature is not lower than the second temperature in a case where the difference does not lie within the allowable range.
