Acceleration control device haptic feedback control

Abstract

A system for generating haptic feedback to an operator of a motor vehicle includes a powertrain for generating vehicle propulsion. The system also includes an acceleration control device having a range of travel positions for regulating powertrain torque and vehicle acceleration. The system additionally includes a vibration transducer configured to mechanically vibrate the acceleration control device. The system also includes a vehicle sensor for detecting the operator's request for generation of the powertrain torque and acceleration of the motor vehicle and an electronic controller in communication with the vehicle sensor. The controller receives the operator's request and selectively applies, via the vibration transducer, vibration to the acceleration control device in correlation with the operator's request. The controller additionally modulates characteristic(s) of the applied vibration according to vibration command parameters and associated with a change in position and/or time derivatives of the change in position of the acceleration control device.
