Haptic Warning Signals at the Steering Wheel: A Literature Survey Regarding Lane Departure Warning Systems (Short Paper)
MetadataShow full item record
Using the haptic modality to transfer information to the driver is recognized as a promising possibility in many in-vehicle applications. In the field of lane departure warning systems, several haptic warning signals were presented in the last years. The application of synthetic steering wheel torque or vibration informs the driver of an imminent lane departure. In this paper, an approach to classify the existing signals is provided. The examination of the literature reveals diversity in type and parameterization of the warning signals as well as methodical differences, complicating comparability. While the general effectiveness of haptic warning signals at the steering wheel could be proven, there still is room for improvement. Based on the findings, the authors derive hy- potheses concerning requirements from a user’s point of view.
