Abstract

A system for adjusting acceleration of a vehicle based on user preference includes a memory designed to store first and second base vehicle acceleration modes each corresponding to a different pre-selected acceleration profile of the vehicle, and a power source for generating power. The system also includes an input device designed to receive a selected base acceleration mode and a user acceleration adjustment indicating a desired adjustment to the selected base acceleration mode. The system also includes an ECU designed to control the power source to accelerate the vehicle using the selected base acceleration mode during an initial trip of the vehicle, create a first user acceleration profile that corresponds to the desired adjustment to the selected base acceleration mode when the user acceleration adjustment is received, and control the power source to accelerate the vehicle using the first user acceleration profile during a second trip of the vehicle.
