Abstract
A control system for a continuously variable transmission (CVT) is provided. The control system includes a shift mode switch, an actuator and a controller. The shift mode switch is selectable between a plurality of modes. The actuator is in operational communication with the CVT to selectively override normal shifting characteristics of the CVT. The controller is in communication with the shift mode switch. The controller is configured to control the actuator to selectively override the normal shifting characteristics of the CVT based at least in part on a select mode configuration selected by the shift mode switch.
Claims20
A control system for a continuously variable transmission (CVT), the control system comprising:
- a shift mode switch selectable between a plurality of modes;
- an actuator in operational communication with the CVT to selectively override normal shifting characteristics of the CVT;
- and
- a controller in communication with the shift mode switch, the controller configured to control the actuator to selectively override the normal shifting characteristics of the CVT based at least in part on a select mode configuration selected by the shift mode switch.
A vehicle comprising:
- a motor to generate engine torque;
- a drivetrain;
- a continuously variable transmission (CVT) positioned communicate torque between the motor and the drivetrain at a select ratio;
- a shift mode switch selectable between a plurality of modes;
- an actuator in operational communication with the CVT to selectively override normal shifting characteristics of the CVT;
- and
- a controller in communication with the shift mode switch, the controller configured to control the actuator to selectively override the normal shifting characteristics of the CVT based at least in part on a select mode configuration selected by the shift mode switch.
A method of controlling a continuously variable transmission (CVT), the method comprising:
- detecting the activation of a multi-mode shift mode switch;
- and
- implement operating instructions to adjust a shifting characteristics of the CVT associated with a mode indicated by the activated shift mode switch based at least in part on the position of the activated shift mode switch.
