System and method for determining probability that a vehicle driver is associated with a driver identifier

A method for driver identification comprising:

• recording a first image of a vehicle driver at an interior-facing camera of a vehicle system during a driving session;
• computing a first probability that the vehicle driver is associated with a driver identifier based on the first image;
• in response to the first probability falling below a first threshold value, recording a second image of the vehicle driver, and recomputing the first probability that the vehicle driver is associated with the driver identifier based on the first image and the second image;
• in response to the first probability exceeding the first threshold value, transmitting the first and second images to a remote computing system;
• extracting a feature vector from the first and second images at a feature extraction module of the remote computing system;
• determining a set of auxiliary sensor signals;
• computing a second probability that the vehicle driver is associated with the driver identifier based on the feature vector in combination with the set of auxiliary sensor signals;
• associating the driver identifier with the driving session based on the second probability;
• in response to the second probability exceeding a second threshold value, automatically associating the driving session with the driver identifier;
• in response to the second threshold value exceeding the second probability and the second probability exceeding a third threshold value, receiving a driver identification input from a user and associating the driving session with a user-selected driver identifier;
• and
• in response to the third threshold value exceeding the second probability, generating a new driver identifier corresponding to the feature vector in combination with the auxiliary sensor signal and associating the new driver identifier with the driving session.
