Systems and methods for haptic feedback control in a vehicle
First Claim
1. A control system for a vehicle, the control system comprising:
- a first module selected from an adaptive cruise control system, a heating, ventilation, and air conditioning system, and an audio system, the first module receiving input from an operator of the vehicle via an input device, said input device selected from and comprising of at least one of a joystick, an electroactive polymer over a printed circuit board, and a steering wheel input device, wherein the operator input includes a change to an operating parameter of a vehicle system; and
a second module that selectively adjusts a resistance to the input of the input device based on the change in the operating parameter, wherein;
the second module increases the resistance by a predetermined amount such that the resistance incrementally increases by the predetermined amount when determining that the operating parameter is less than a minimum threshold or the operating parameter is greater than a maximum threshold,the second module immediately sets the resistance directly to a maximum resistance such that the resistance is increased directly to the maximum resistance when determining that the operating parameter is greater than the minimum threshold and is less than the maximum threshold, andthe predetermined amount is set such that when the resistance is at a default level, the resistance is increased to a value between the default level and the maximum resistance.

Abstract
A control system for a vehicle includes first and second modules. The first module receives input from an operator of the vehicle via an input device, wherein the operator input includes a change to an operating parameter of a vehicle system. The second module selectively adjusts a resistance of the input device based on the operator input and a predetermined threshold. A method for controlling a vehicle includes receiving input from an operator of the vehicle via an input device, wherein the operator input includes a change to an operating parameter of a vehicle system, and selectively adjusting a resistance of the input device based on the operator input and a predetermined threshold.
