DRIVING OPERATION DETERMINER, DRIVING OPERATION DETERMINATION SYSTEM, DRIVING OPERATION DETERMINATION METHOD, AND STORAGE MEDIUM STORING PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18212221 titled 'DRIVING OPERATION DETERMINER, DRIVING OPERATION DETERMINATION SYSTEM, DRIVING OPERATION DETERMINATION METHOD, AND STORAGE MEDIUM STORING PROGRAM

Simplified Explanation

The abstract of this patent application describes a driving operation determiner that uses lever operation information and yaw rate information to determine certain conditions related to the operation of a turn signal lever in a vehicle.

  • The determiner analyzes the lever operation information to determine if the turn signal lever has been switched from a non-operation state to an operation state at a first time, and then switched back to the non-operation state at a second time.
  • It also analyzes the yaw rate information to calculate the difference between the maximum and minimum values of the yaw rate within an identified duration between the first and second times.
  • The determiner then compares this difference to a first threshold value and checks if the absolute value of the maximum yaw rate value is at least a second threshold value.

Potential applications of this technology:

  • Vehicle safety systems: The determiner can be used in vehicle safety systems to detect and analyze the operation of turn signal levers and the yaw rate of the vehicle. This information can be used to provide warnings or alerts to the driver or other vehicles on the road.
  • Driver assistance systems: The determiner can be integrated into driver assistance systems to provide additional information for features like lane change assist or blind spot detection. By analyzing the turn signal lever operation and yaw rate, the system can better understand the driver's intentions and provide appropriate assistance.

Problems solved by this technology:

  • Accurate turn signal detection: The determiner solves the problem of accurately detecting the operation of a turn signal lever by considering both the lever operation information and the yaw rate information. This ensures that the system can differentiate between intentional turn signal operation and accidental lever movements.
  • Enhanced safety: By analyzing the difference in yaw rate and the maximum yaw rate value, the determiner can identify situations where the vehicle is undergoing significant changes in direction. This information can be used to enhance safety systems and provide timely warnings or interventions.

Benefits of this technology:

  • Improved driver assistance: By accurately detecting turn signal operation and analyzing the yaw rate, the technology can enhance driver assistance systems and provide more accurate and timely assistance to the driver.
  • Enhanced safety: The technology contributes to enhanced safety by providing better understanding of the vehicle's movements and intentions, allowing for improved warning systems and interventions.


Original Abstract Submitted

A driving operation determiner that is configured to: based on lever operation information representing whether or not a turn signal lever of a vehicle is operated, and based on yaw rate information representing a yaw rate of the vehicle, make a determination as to whether, in an identified duration between a first time and a second time, a difference between a maximum value and a minimum value of the yaw rate is at least a first threshold value and an absolute value of the maximum value of the yaw rate is at least a second threshold value, the turn signal lever being switched from a non-operation state to an operation state at the first time, and the turn signal lever being switched from the operation state to the non-operation state at the second time subsequent to the first time.
