US 12,668,281 B1 · Database generation including predicted scenarios

Abstract

Techniques for generating a database containing predicted driving scenarios are discussed herein. A database management component may receive sensor data captured by sensors of vehicle(s) (e.g., driving log data) based on previous driving trips within various physical driving environments. The database management component may cluster driving scenarios observed from the sensor data based on the driving scenario's feature similarity. In some examples, the database management component may determine prediction information (e.g., actual trajectory from log data or trajectory generated by machine-learning model) to associate with each cluster. Accordingly, each cluster may include an encoded representation (e.g., key) as well as corresponding prediction information (e.g., value). In some examples, the database management component may store some or all key-value pairs in a database accessible by one or more vehicles while such vehicles navigate an environment.

Dependent claims

A system comprising:

one or more processors;
and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to perform operations comprising:
receiving log data associated with an environment, wherein the log data is representative of a set of driving scenarios that were experienced at a previous time;
inputting the log data into a machine-learning model;
receiving, from the machine-learning model, a set of encoded data representative of the set of driving scenarios;
determining, based at least in part on the set of encoded data, a cluster of encoded data of the set of encoded data representative of driving scenarios of the set of driving scenarios;
determining, based at least in part on the cluster of encoded data associated with the driving scenarios, prediction information associated with an object in the cluster of the encoded data associated with the driving scenarios;
storing, in a database, the cluster and the prediction information;
and
transmitting the database to an autonomous vehicle configured to be controlled based at least in part on the database.
