METHODS AND SYSTEMS FOR VEHICLE CONTROL UNDER DEGRADED LANE PERCEPTION RANGE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18063650 titled 'METHODS AND SYSTEMS FOR VEHICLE CONTROL UNDER DEGRADED LANE PERCEPTION RANGE
Simplified Explanation
The patent application describes methods and systems for controlling a vehicle by switching to a second processor executed mode when perception information extends closer to the vehicle than a predetermined point. In this mode, a lateral controller provides a closer Look Ahead point to the motion planner, which generates a desired trajectory based on perception data.
- The system switches to a second processor executed mode when perception information extends closer to the vehicle than a predetermined point.
- A lateral controller provides a closer Look Ahead point to the motion planner in the second mode.
- The motion planner generates a desired trajectory based on perception data and the closer Look Ahead point.
- Control commands for an EPS system are generated based on the error between the desired trajectory and the actual trajectory at the closer Look Ahead point.

Original Abstract Submitted
Methods and systems of controlling a vehicle. The methods and systems include switching to a second processor executed mode in response to determining that a range of perception information extends to a range end point that is closer to the vehicle than a first Look Ahead (LA) point. In the second processor executed mode: a motion planner requests a lateral controller to provide a closer LA point relative to the vehicle. The lateral controller determines the closer LA point and sends the closer LA point to the motion planner. The lateral controller generates control commands for an EPS system based on an error between a desired trajectory and an actual trajectory at the closer LA point. The motion planner generates the desired trajectory based on perception data and the closer LA point.
