Abstract

A powertrain / driveline warm-up system includes a vehicle controller, an electrical power source interfacing with the vehicle controller, at least one heater interfacing with the vehicle controller and at least a portion of a vehicle powertrain provided in thermal contact with the at least one heater.

Description

technical field [0001] The present invention generally relates to vehicle powertrains. More particularly, the present invention relates to powertrain / driveline warm-up systems and methods wherein powertrain / drivetrain oil is heated prior to and / or during vehicle start to reduce oil viscosity and improve vehicle fuel economy sex. Background technique [0002] The powertrain of a motor vehicle (engine and transmission, front and rear differentials, transfer case, power split management unit, and axle bearings) is typically lubricated by powertrain oils, which reduce wear and operating temperatures on powertrain components during vehicle operation . When the vehicle starts running, the powertrain fluid is cold and viscous. Therefore, lukewarm oil exerts resistance to the movement of powertrain components, which can reduce the vehicle's fuel economy through parasitic power loss. [0003] Accordingly, there is a need for a powertrain warm-up system and method in which powertr...
