Abstract

An oil pump is connected to an electric motor and receives driving power, and the oil pump operates normally in a forward direction at normal times regardless of whether the electric motor operates in the forward or reverse direction thereof. Therefore, according to A system for operating an oil pump for a vehicle, the oil pump, which operates in conjunction with the electric motor, is applied, which reduces costs in comparison with an electric oil pump. Furthermore, regardless of whether the electric motor operates in the forward or reverse direction, the oil pump operates normally, which normally circulates oil and stabilizes components of an oil system.
