Abstract:
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.

Claim (Index 1):
A drive system comprising:\n a drive motor; a continuously variable transmission (CVT) comprising a plurality of spherical planets arranged about a longitudinal axis of the CVT; and a control system communicatively coupled to the CVT, the control system comprising\n an actuator coupled to the CVT, \n a CVT controller communicatively coupled to the actuator and a plurality of sensors, wherein a first sensor sends a first signal associated with battery status, a second sensor sends a second signal associated with throttle position, a third sensor sends a third signal associated with throttle rate, and a fourth sensor sends a signal associated with vehicle speed, wherein the CVT controller is configured to perform\n sending, to a data display, a plurality of operating mode options, \n receiving, via the data display, an indication of an operating mode selected by a user, and \n sending a command to the actuator to adjust an angle of the spherical planets based on the indication of the selected operating mode and a signal from a sensor of the plurality of sensors.
