Title: Rui Chen and Three-Dimensional Trajectory Planning for Autonomous Parking.

Introduction

Rui Chen is an inventor associated with Bloomfield Hills, Michigan, and Aptiv Technologies AG. His work includes a patent on trajectory planning for autonomous parking in a three-dimensional search space.

Latest Patents

Chen is named on 1 patent: “Trajectory Planning in a Three-Dimensional Search Space with a Space-Time Artificial Potential Field.” The patent describes a system that uses a parking trajectory algorithm to search a space-time artificial potential field. A processor considers an initial pose, a goal pose, and an obstacle map, then determines a trajectory made up of three-dimensional waypoints that combine two-dimensional positions with time coordinates. The vehicle can follow this trajectory using assisted-driving or autonomous-driving controls. Searching the full three-dimensional space in a single iteration can support motion planning around both static and dynamic obstacles.

Career Highlights

Chen’s patent work addresses a challenge in autonomous parking: planning a vehicle’s movement while accounting for obstacles and timing. The described approach searches the full space-time environment rather than repeatedly switching between two-dimensional search planes.

Collaborations

The provided information identifies Qian Wang as Chen’s coworker. Chen is also associated with Aptiv Technologies AG, the company connected to his patent work.

Conclusion

Rui Chen’s patent presents a space-time approach to autonomous parking that aims to plan vehicle trajectories efficiently amid obstacles.
