A haptic-based traction control system

This paper presents a haptic support system for traction control (HTC). The haptic gas pedal exerts a wheel slip dependent force; this enables an efficient information transfer so that the driver is able to close the loop. The paper presents the basic rationale and validates it with an experimental campaign carried out with a driver-in-the-loop simulator. Two challenging driving scenarios are explored with numerous test subjects. The system improves safety without negatively affecting performance. The occurrences of loss of control are reduced from 35% without HTC to 10% with HTC. The subjective feedback from the test drivers is also analyzed, showing a good level of acceptance.
