Abstract
Methods and systems for operating a vehicle include prompting a large language model LLM to generate parameters for a rule-based planner based on historical data for vehicles in a road scene. A trajectory is generated using the parameters. A driving action is performed to implement the trajectory.
Claims20
A computer-implemented method for operating a vehicle, comprising:
- prompting a large language model (LLM) to generate parameters for a rule-based planner based on historical data for vehicles in a road scene;
- generating a trajectory using the parameters;
- and
- performing a driving action to implement the trajectory.
1 more element
A system for operating a vehicle, comprising:
- a hardware processor;
- and
- a memory that stores a computer program which, when executed by the hardware processor, causes the hardware processor to:
- prompt a large language model (LLM) to generate parameters for a rule-based planner based on historical data for vehicles in a road scene;
- generate a trajectory using the parameters;
- and
- perform a driving action to implement the trajectory.
4 more elements
A vehicle, comprising:
- a hardware processor;
- an equipment control unit (ecu) that controls at least one driving system of the vehicle;
- and
- a memory that stores a computer program which, when executed by the hardware processor, causes the hardware processor to:
- prompt a large language model (LLM) to generate parameters for a rule-based planner based on historical data for vehicles in a road scene;
- generate a trajectory using the parameters;
- and
- trigger the ECU to perform a driving action to implement the trajectory, selected from the group consisting of a braking action, a steering action, and an acceleration action.
