Abstract

A control system, a hybrid control module, and method for controlling a hybrid vehicle are provided. The hybrid control module includes a computer and a plurality of predefined values and steps stored and implemented by the computer in response to a signal from the hybrid control module and input from an operator. Each of the plurality of predefined values and steps controls a component of the hybrid vehicle or controls a plurality of functions within the hybrid control module. The hybrid control module provides conventional vehicle functionality and feel to the hybrid vehicle in response to operator input.
