Title:
車両用駆動装置の制御装置
Document Type and Number:
Japanese Patent JP6428672
Kind Code:
B2
Abstract:
A rotation speed of an electric oil pump in the case where an accelerator operation amount falls within a predetermined range is controlled to a rotation speed lower than the rotation speed of the electric oil pump in the case where the accelerator operation amount falls outside the predetermined range. When the range outside the predetermined range of the accelerator operation amount is set to a range in which noise that occurs from a source other than the electric oil pump is large, noise that occurs from the electric oil pump is masked by the noise that occurs from a source other than the electric oil pump and becomes inconspicuous in this range even when the rotation speed of the electric oil pump increases.
