SYSTEMS AND METHODS FOR CONTROL OF TRANSMISSION AND/OR PRIME MOVER |
| 摘要 |
Disclosed here are inventive systems and methods for a powertrain of an electric vehicle (EV). In some embodiments, said powertrain includes 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. In one specific embodiment, the 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 disclosed. 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. |

1. A drive system comprising:
a drive motor; a motor controller communicatively coupled to the drive motor; a continuously variable transmission (CVT) having a plurality of tiltable spherical planets arranged radially about a longitudinal axis of the CVT; a transmission control system coupled to the CVT, the transmission control system comprising
a controller configured to be in electrical communication with an actuator configured to adjust an angle of the tiltable spherical planets, the controller configured to control the actuator to change a speed ratio of the CVT,a first sensor configured to provide vehicle speed data,a second sensor configured to provide data associated with the transmission speed ratio of the CVT, anda third sensor configured to provide data associated with a battery voltage; and a data display in electrical communication with the controller, the data display having at least one button for selecting from a plurality of operating modes. |
