SYSTEM AND METHOD FOR TRAJECTORY PLANNING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240239373 titled 'SYSTEM AND METHOD FOR TRAJECTORY PLANNING

Simplified Explanation:

This patent application describes a system and method for trajectory planning for autonomous vehicles. The system selects a trajectory from multiple options based on global and local scene information, identifying obstacles and actors on the roadway to ensure safe navigation.

• The system includes a controller, GPS, and sensors for collecting global and local scene information.
• The controller processes this information to identify obstacles, determine occluded portions of the roadway, and calculate contracted occluded portions.
• Candidate trajectories are generated, scored, and one is selected for the autonomous vehicle based on the score assigned.

Key Features and Innovation:

• Utilizes global and local scene information for trajectory planning.
• Identifies occluding obstacles and scene actors on the roadway.
• Calculates contracted occluded portions within obstacles for safe navigation.

Potential Applications:

• Autonomous vehicles navigation systems.
• Traffic management systems.
• Safety systems for vehicles.

Problems Solved:

• Ensures safe navigation in complex environments.
• Improves decision-making for autonomous vehicles.
• Enhances obstacle detection and avoidance.

Benefits:

• Increased safety on the roads.
• Efficient trajectory planning for autonomous vehicles.
• Enhanced obstacle detection capabilities.

Commercial Applications: Autonomous vehicle technology for transportation companies, smart city initiatives, and automotive manufacturers.

Prior Art: Readers can explore prior art related to trajectory planning for autonomous vehicles, obstacle detection systems, and advanced driver assistance systems.

Frequently Updated Research: Stay updated on advancements in autonomous vehicle technology, obstacle detection algorithms, and trajectory planning methods.

Questions about trajectory planning for autonomous vehicles: 1. How does this system improve safety for autonomous vehicles in complex environments? 2. What are the key factors considered when selecting a trajectory for an autonomous vehicle?

Original Abstract Submitted

a system and method for trajectory planning selects a trajectory from a plurality of candidate trajectories to direct an autonomous vehicle. the system includes a controller in communication with a global positioning system (gps) and at least one sensor. the gps receives a plurality of global scene information. the at least one sensor collects local scene information. the controller is programmed to receive global scene information and local scene information, identify the location of the occluding obstacle. additionally, the controller is programmed to determine an occluded portion of the roadway, identify a location of the scene actors on the roadway, and calculate a contracted occluded portion within the occluded portion. furthermore, the system generates candidate trajectories for the autonomous vehicle to travel along, score the candidate trajectories, and select one of the candidate trajectories based on the assigned score.
