Training algorithm for collision avoidance using auditory data
First Claim
1. A method comprising:
- defining, by a computer system, a three dimensional (3D) model;
simulating, by the computer system, two or more sensor outputs from sound from a parked vehicle with its engine running incident on two or more sensor locations of a subject vehicle in the 3D model; and
training, by the computer system, a machine-learning model using a location of the parked vehicle in the 3D model and the two or more sensor outputs.

Abstract
A machine learning model is trained by defining a scenario including models of vehicles and a typical driving environment. A model of a subject vehicle is added to the scenario and sensor locations are defined on the subject vehicle. A perception of the scenario by sensors at the sensor locations is simulated. The scenario further includes a model of a parked vehicle with its engine running. The location of the parked vehicle and the simulated outputs of the sensors perceiving the scenario are input to a machine learning algorithm that trains a model to detect the location of the parked vehicle based on the sensor outputs. A vehicle controller then incorporates the machine learning model and estimates the presence and/or location of a parked vehicle with its engine running based on actual sensor outputs input to the machine learning model.

12. A system comprising one or more processors and one or more memory devices coupled to the one or more processors, the one or more memory devices storing executable code effective to:
-
define a three dimensional model including a parking area and a plurality of stationary parked vehicles, a running parked vehicle, and a subject vehicle including two or more sensor locations positioned on the parking area; simulate two or more sensor outputs from sound from the running parked vehicle incident on the two or more sensor locations; and train a machine-learning model using a location of the stationary parked vehicle and the two or more sensor outputs over time. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
