Abstract:
1. A control apparatus of an electric oil pump which supplies oil to a vehicle drive system, comprising: an oil temperature measuring section which measures an oil temperature; a trial operation control section which performs a trial operation in a state in which a drive current of the electric oil pump is limited to be less than a required drive current of the electric oil pump, and performs the trial operation in a state in which the trial operation control section does not establish a malfunction determination of the electric oil pump when the measured oil temperature is in a temperature range in which operation of the electric oil pump is susceptible to measurement error due to a fluctuation of the oil temperature measuring section; and a regular operation allowing determining section which allows a regular operation of the electric oil pump while allowing the malfunction determination of a main body of the electric oil pump when a rotation number increasing state of the electric oil pump subjected to the trial operation satisfies a regular operation allowing condition, and which stops driving of the electric oil pump when the rotation number increasing state does not satisfy the regular operation allowing condition.
