1. A method, comprising:
- assigning a first number of simulated transmission gears to a first number of gear shifter position slots, the first number of simulated transmission gears greater than the first number of gear shifter position slots; and
simulating shifting of a multiple-step gear ratio transmission for a driveline having a single fixed-ratio gear box in response to a position of a gear shifter in a gear shifter position slot included in the first number of gear shifter position slots, and where simulating shifting of the multiple-step gear ratio transmission is performed via limiting torque output of a motor in the driveline.

Abstract
Systems and methods for operating and interfacing to a transmission of a vehicle are presented. In one example, a human machine interface allows a driver to assign gear ratios or simulated gear ratios to gear position slots of a shifter. The assignment of gear ratios to gear position slots of a shifter may allow a driver to experience the feeling of driving a manually shifted transmission without having to operate a clutch.

8. A method, comprising:
-
prompting a driver to assign a first number of simulated transmission gears to a first number of gear shifter position slots; and simulating shifting a transmission of a driveline when a position of a gear shifter moves from a first gear shifter position slot to a second gear shifter position slot, the first gear shifter position slot and the second gear shifter position slot included in the first number of gear shifter position slots, where the driveline includes a continuously variable transmission or a single fixed gear ratio gear box, and where the driveline does not include a multiple-step gear ratio transmission. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A vehicle system, comprising:
-
a human machine interface; a motor; a single fixed gear ratio gear box in communication with the motor; and a controller including non-transitory instructions executable to prompt a driver to assign a plurality of simulated transmission gear ratios to a plurality of gear shifter position slots via the human machine interface, and additional instructions to simulate shifting through the plurality of simulated transmission gear ratios via the motor in response to vehicle operating conditions. - View Dependent Claims (16, 17, 18, 19, 20)
