20230026400 · 2023-01-26 ·

Directional vehicle steering cues are presented to a vehicle operator to suggest a particular steering direction (e.g., left vs. right) or to warn the operator of the directionality of an impending hazard. A directional vehicle steering cue may include one or more changes in steering angle that convey an associated directionality. A directional steering cue can include a first vibration pattern that includes a change in steering angle in a first direction to represent, for example, a suggested right turn, followed by a second vibration pattern that includes a change in steering angle in a second direction opposite to the first direction. The angular rate of change of the steering angle in the first direction may be larger than the angular rate of change of the steering angle in the second direction such that the first vibration pattern is more perceptible to a vehicle operator than the second vibration pattern.
