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 20240035846 titled 'METHOD AND DEVICE FOR DETERMINING THE RELIABILITY OF A LOW-DEFINITION MAP
Simplified Explanation
The invention is a method and device for determining the reliability of a low-definition map in order to improve the reliability of the activation of driving-assistance systems in an autonomous vehicle. The autonomous vehicle has a navigation system and a perception system. The navigation system includes a map that provides information about the slope and curvature of the road around the vehicle, referred to as mapped slope and mapped curvature. The perception system provides information about the measured slope and trajectory of the road, referred to as measured slope and measured trajectory.
- The method involves comparing the mapped slope and curvature with the measured slope and trajectory to determine the reliability of the map.
- The device includes sensors and processors to collect and analyze data from the navigation and perception systems.
- The device uses algorithms to calculate the difference between the mapped and measured values and determine the reliability of the map.
- The device can activate driving-assistance systems based on the reliability of the map, improving the overall performance and safety of the autonomous vehicle.
Potential applications of this technology:
- Autonomous vehicles: This technology can be used in autonomous vehicles to improve the reliability of driving-assistance systems, enhancing the safety and performance of the vehicle.
- Transportation industry: The invention can be applied in the transportation industry to enhance the reliability of autonomous vehicles, leading to more efficient and safer transportation systems.
Problems solved by this technology:
- Inaccurate maps: The invention addresses the problem of using low-definition maps in autonomous vehicles by determining their reliability and improving the activation of driving-assistance systems.
- Safety concerns: By improving the reliability of driving-assistance systems, this technology helps address safety concerns associated with autonomous vehicles.
Benefits of this technology:
- Enhanced reliability: The invention improves the reliability of driving-assistance systems by determining the reliability of low-definition maps, leading to safer and more efficient autonomous vehicles.
- Improved performance: By accurately assessing the reliability of the map, the technology ensures that driving-assistance systems are activated when necessary, enhancing the overall performance of the autonomous vehicle.
