APPARATUS FOR MANAGING FLUID FLOW IN A VEHICLE

摘要

Apparatus for managing fluid flow in a vehicle, comprising: an epicylic gear set having first and second inputs configured to receive rotational drive input from a torque output feature of a powertrain and a rotary actuator respectively; a pump driver for driving a fluid pump, the pump driver configured to receive rotational drive input from an output of the epicylic gear set; and a controller configured to determine information corresponding to the rotational speed of the torque output feature using information generated by a rotational speed sensor and based on this control the rotary actuator such that the pump driver is caused to rotate at substantially a pre-specified speed.
