METHOD AND DEVICE FOR DETERMINING THE RELIABILITY OF A LOW-DEFINITION MAP - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240035845 titled 'METHOD AND DEVICE FOR DETERMINING THE RELIABILITY OF A LOW-DEFINITION MAP

Simplified Explanation

The invention is a method for determining the reliability of a low-definition map to ensure the activation of driving assistance systems in an autonomous vehicle. The autonomous vehicle is equipped with a navigation system that provides mapped data and a perception system that provides measured data of the vehicle and/or the external environment.

  • The method involves evaluating the reliability of a low-definition map used by the navigation system.
  • The reliability is determined by comparing the mapped data from the low-definition map with the measured data from the perception system.
  • The comparison helps identify any discrepancies or inconsistencies between the map and the actual environment.
  • The method also includes analyzing the reliability of the perception system itself, ensuring accurate measurement of the vehicle and its surroundings.
  • By determining the reliability of the low-definition map and the perception system, the method ensures the activation of driving assistance systems in the autonomous vehicle is reliable.

Potential applications of this technology:

  • Autonomous vehicles: This method can be applied to enhance the reliability of driving assistance systems in autonomous vehicles, improving their overall safety and performance.
  • Navigation systems: The method can be used to evaluate the reliability of low-definition maps used in navigation systems, ensuring accurate guidance for drivers.

Problems solved by this technology:

  • Inaccurate maps: The method addresses the issue of using low-definition maps that may not accurately represent the actual environment, ensuring reliable activation of driving assistance systems.
  • Measurement discrepancies: By comparing the mapped data with the measured data, the method helps identify any discrepancies or inconsistencies, allowing for corrective actions to be taken.

Benefits of this technology:

  • Improved safety: By ensuring the reliability of the low-definition map and perception system, the method enhances the safety of autonomous vehicles by enabling reliable activation of driving assistance systems.
  • Enhanced performance: The method helps optimize the performance of autonomous vehicles by providing accurate and reliable data for driving assistance systems.
  • Efficient navigation: By evaluating the reliability of low-definition maps, the method ensures accurate guidance for drivers, improving navigation efficiency.
