Continuously variable transmission tap gear entry ratio selection during transient driving conditions

A method of selecting a continuously variable transmission manual mode entry ratio during transient driving conditions of an automobile vehicle, comprising:

• providing a continuously variable transmission (CVT) connected to an engine;
• controlling the engine and the CVT using a controller;
• positioning a shift device in communication with the controller allowing selection by an operator of the automobile vehicle between a Park mode, a Reverse mode, a Neutral mode, a Drive mode and a Manual mode;
• splitting a range of ratios of the CVT into multiple bins independently defining successive segments of the range of ratios;
• and
• selecting a predicted ratio of the CVT at a time of entrance into the Manual mode at a center of one of the multiple bins adjacent to a CVT real ratio.

A method of selecting a transmission manual mode entry gear during transient driving conditions of an automobile vehicle, comprising:

• shifting a PRNDL shift device to a Manual position to shift a continuously variable transmission (CVT) to a manual mode;
• applying an offset to a real ratio of the CVT;
• rounding the real ratio to a bin ratio center of a bin adjacent to the real ratio in a direction of a shift;
• determining if a calculated entry ratio will cause the shift to pass a requested ratio;
• entering the manual mode at the calculated entry ratio if the calculated entry ratio will not cause the shift to pass the requested ratio;
• and
• entering the manual mode at a desired ratio if the calculated entry ratio will cause the shift to pass the desired ratio.
