Oil Pump Control tor Multiple Oil Pumps

摘要

Using an inertial measurement unit (imu), such as a yaw sensor, wheel speed sensor, or steering wheel angle sensor to determine transmission oil management system state will Improve oil pump efficiency and performance. Moreover, a potential exists to eliminate undeslred performance effects of pump-to-pump production variation matching for pump architectures containing two or more pumps that have interdependence. Primary and downstream pump flow rates must be considered and matched to prevent oil starving under operating condition. This phenomenon creates objectionable noise and durability issues for pumps.
