ATTENTION CALLING SYSTEM AND ATTENTION CALLING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18455923 titled 'ATTENTION CALLING SYSTEM AND ATTENTION CALLING METHOD

Simplified Explanation

The patent application describes an attention-calling system that includes acquiring time headway (THW) and time to collision (TTC) values to notify the occupant of a vehicle of an approaching vehicle. The system determines the saliency level of the approach alarm based on the THW and TTC values.

  • Time headway (THW) acquisition unit acquires THW at predetermined intervals
  • Time to collision (TTC) acquisition unit acquires TTC at predetermined intervals
  • Notification unit outputs approach alarm to notify occupant of approaching vehicle based on THW and TTC
  • Notification unit determines saliency level of approach alarm based on THW and TTC

Potential Applications

- Advanced driver assistance systems - Collision avoidance systems - Vehicle safety technologies

Problems Solved

- Alerting drivers of potential collisions - Improving driver awareness of surrounding vehicles - Enhancing vehicle safety measures

Benefits

- Increased safety on the road - Reduced risk of accidents - Improved driver response time to potential hazards

Potential Commercial Applications

Enhanced Vehicle Safety Technologies

Possible Prior Art

There may be existing systems or patents related to driver assistance systems or collision avoidance technologies that address similar issues of alerting drivers to potential collisions.

Unanswered Questions

How does the system differentiate between different levels of saliency for the approach alarm?

The patent application mentions determining a saliency level for the approach alarm, but it does not specify the criteria or algorithm used for this determination.

What is the accuracy and reliability of the THW and TTC values acquired by the system?

The patent application describes acquiring THW and TTC values at predetermined intervals, but it does not mention the accuracy or reliability of these values in real-world driving scenarios.


Original Abstract Submitted

An attention calling system includes a time headway (THW) acquisition unit repeatedly acquiring THW at predetermined time intervals, the THW being a value obtained by dividing an inter-vehicle distance between an own vehicle and a preceding vehicle by vehicle speed of the own vehicle, a time to collision (TTC) acquisition unit repeatedly acquiring TTC at predetermined time intervals, the TTC being a value obtained by dividing the inter-vehicle distance by relative speed between the own vehicle and the preceding vehicle, and a notification unit outputting to an occupant of the own vehicle an approach alarm that notifies an approach to the preceding vehicle, based on the THW and the TTC. The notification unit determines a saliency level that is a degree of saliency of the approach alarm in accordance with the THW and the TTC, and outputs the approach alarm of the determined saliency level.
