Electric vehicle

摘要

An electric vehicle such as an electric motorcycle includes a driving motor which activates a wheel via a driving power transmission mechanism (e.g., transmission), a mechanical oil pump which is mechanically activated by the driving motor to feed oil to the driving power transmission mechanism, and an electric oil pump which feeds the oil to the driving power transmission mechanism. A controller causes the electric oil pump to initiate its operation before the driving motor in a deactivated state initiates its operation under a specified condition, thus preventing a situation in which there is no lubrication oil in the driving power transmission mechanism during starting.

主权项

1. An electric vehicle comprising:
an electric motor which activates a wheel via a driving power transmission mechanism to move a vehicle body; a mechanical oil pump which is mechanically activated by the electric motor to feed oil to the driving power transmission mechanism; an electric oil pump which feeds the oil to the driving power transmission mechanism; and a controller which controls the electric oil pump such that the electric oil pump in a deactivated state initiates its operation, before the electric motor in a deactivated state initiates its operation under a specified condition, wherein the controller controls the electric oil pump in such a manner that a rotational speed of the electric oil pump is set according to a displacement amount of an accelerator.
