<p>PROBLEM TO BE SOLVED: To suppress influences on traveling performance and operability of a vehicle, even when a variable displacement oil pump cannot be switched to an operational state at a high hydraulic oil pressure side.SOLUTION: A control device of an engine including various auxiliary machines, includes a variable displacement oil pump 2 for supplying oil to the engine 1 and the auxiliary machines 5, a solenoid valve 3 for switching hydraulic oil pressure generated in the oil pump between high pressure and low pressure, and an ECU 4 for controlling the engine and the auxiliary machines. When the oil pump 2 cannot be switched to an operational state at a high hydraulic oil pressure side in supplying the oil to the engine 1 and the auxiliary machines 5 by the oil pump 2, an operation using the oil discharge from the oil pump 2, is suppressed by the control of the ECU 4.</p> |
