Patent number: 10703372Abstract: Disclosed here are inventive systems and methods for a powertrain of an electric vehicle (EV) having a continuously variable transmission (CVT) coupled to an electric drive motor, wherein a control system is configured to control the CVT and/or the drive motor to optimize various efficiencies associated with the EV and/or its subsystems. A control system is configured to operate the EV in an economy mode. Operating in said mode, the control system simultaneously manages the CVT and the drive motor to optimize the range of the EV. The control system can be configured to manage the current provided to the drive motor, as well as adjust a transmission speed ratio of the CVT. Other modes of operation are also possible. The control system can be configured to manage the power to the drive motor and adjust the transmission speed ratio of the CVT taking into account battery voltage, throttle position, and transmission speed ratio, for example.Type: GrantFiled: January 26, 2018Date of Patent: July 7, 2020Assignee: Fallbrook Intellectual Property Company LLCInventors: Jeremy Carter, Brad P. Pohl, Loren T. McDaniel, Cyril Keilers, Tim Ruggles, David Lynn Rogers, Eric Diehl, Austin Orand, Alan Mark Delz, Paul Argus Parks, Mark Edward Bartholomew, Christopher M. Vasiliotis
