Abstract
A method for testing an engine in a vehicle includes arranging a bath separate from the vehicle configured to cool a driveline component of the vehicle, adjusting a temperature of the driveline component to a target temperature, and responsive to the driveline component achieving the target temperature, operating the engine according to a mapping procedure, and controlling the bath to maintain the temperature of the driveline component at the target temperature during the operating. The method further includes measuring heat transfer from the driveline component to the bath during the operating, and calculating torque loss or energy loss of the driveline component during the operating based on the heat transfer.
