Abstract
A headway between a first vehicle and a second vehicle is determined. A predicted time to collision between the first vehicle and the second vehicle is determined. A first mechanism in a wearable device in the first vehicle is actuated when the headway is less than a predetermined threshold. A second mechanism in the first vehicle is actuated when the predicted time to collision is less than a second predetermined threshold.
Claims20
A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the computer to:
- identify an occupant of a first vehicle;
- determine a time difference at which the first vehicle and a second vehicle would pass a predetermined point in a roadway;
- predict a time to collision between the first vehicle and the second vehicle with a forward collision warning subsystem;
- provide a first output in a wearable device of the occupant in the first vehicle when the time difference is less than a predetermined threshold, the first output and the threshold based on the identified occupant;
- and
- then, after providing the first output, provide a second output in the first vehicle when the predicted time to collision is less than a second predetermined threshold.
A method, comprising:
- identifying an occupant of a first vehicle;
- determining a time difference at which the first vehicle and a second vehicle would pass a predetermined point in a roadway;
- predicting a time to collision between the first vehicle and the second vehicle with a forward collision warning subsystem;
- providing a first output in a wearable device of the occupant in the first vehicle when the time difference is less than a predetermined threshold, the first output and the threshold based on the identified occupant;
- and
- then, after providing the first output, providing a second output in the first vehicle when the predicted time to collision is less than a second predetermined threshold.
A system, comprising:
- a wearable device of an occupant in a first vehicle;
- a haptic device in a first vehicle;
- means for identifying the occupant in the first vehicle;
- means for determining a time difference at which the first vehicle and a second vehicle would pass a predetermined point in a roadway;
- means for predicting a time to collision between the first vehicle and the second vehicle with a forward collision warning subsystem;
- means for providing a first output in the wearable device of the occupant in the first vehicle when the time difference is less than a predetermined threshold, the first output and the threshold based on the identified occupant;
- and
- means for providing a second output to the haptic device in the first vehicle after providing the first output when the predicted time to collision is less than a second predetermined threshold.
