22 Claims

1. A computer-implemented method, carried out by a vehicle data recording device in a vehicle, the method comprising:

downloading, from a host data collecting system to the vehicle data recording device, a recording target (T₀) for recording data along a route;

at a current time (t₀), determining a plurality of routes that the vehicle can take;

for each route (Ri) of the plurality of routes, generating a route encoding including encoding in numerical values information on predicted values of the route (Ri) for a plurality of metrics, a metric (v_c_{_k}) of the plurality of metrics being a function assigning a value representing an amount of progress in achieving an elementary recording target value of data;

providing a plurality of route encodings and additional environmental information that is independent of the plurality of routes to a reinforcement learning agent that selects a route of the plurality of routes in order to optimize a reward;

autonomously controlling operation of the vehicle to drive along the selected route or to remain driving along the selected route;

recording data from data sources in the vehicle over time while the vehicle drives along the selected route (Rs); and

uploading at least part of the recorded data from the vehicle data recording device to the host data collecting system.
