SYSTEM AND METHOD FOR THERMAL AND LUBRICATION MANAGEMENT IN ELECTRIC DRIVE MODULE

A thermal management system for an electric drive module configured to generate and transfer drive torque to a driveline for propulsion of an electric vehicle is provided. The system includes a motor housing, a pump, a first and second temperature sensor and a controller. The motor housing has an electric motor and a sump. The pump delivers fluid through a hydraulic circuit to the electric motor. The first temperature sensor senses a first temperature at the pump. The second temperature sensor senses a second temperature at the sump. The controller is configured to: determine an initial pump flow based on a heat losses associated with a speed and torque of the motor; command the pump to operate at an initial speed to satisfy the initial pump flow; compare at least one of the first and second temperatures to a threshold; command the pump to operate at a first modified speed.
