Abstract:
1. A method of transitioning a control system of a vehicle, the method comprising; detecting a requested transition in the operation of the vehicle between one of a first range and a second range to the other of the first range and the second range; selecting at least one state equation that currently describes the one of the first range and the second range in which the vehicle is currently operating in as a current state equation; selecting at least one state equation that describes the one of the first range and the second range that the vehicle is transitioning into as a target state equation; wherein the current state equation includes at least one reference value and at least one state output value that describes the operation of the vehicle when in the first range, and wherein the target state equation includes at least one reference value and at least one state output value that describes the operation of the vehicle when in the second range; defining a multiplier to adjust the values of the current state equation over time; and blending values of the current state equation over time until the blended values are substantially equal to values of the target state equation to smooth the requested transition between the first range and the second range; wherein blending values of the current state equation over time until substantially equal to values of the target state equation includes A) multiplying a difference between the at least one reference value of the current state equation and the at least one reference value of the target state equation by the multiplier to define a reference product, and summing the reference product with the at least one reference value of the current state equation to define an adjusted reference value.
