1. A driving data collection device, comprising:
- a vehicle interface adapted to interface with an on-board diagnostics system of a vehicle and retrieve vehicle parameters of the vehicle from the on-board diagnostics system while the driving data collection device is physically connected to the vehicle;
an output interface adapted to output data by near field communication;
a processor adapted to execute computer program instructions; and
a non-transitory computer readable medium storing executable computer program instructions that when executed by the processor cause the processor to;
analyze the vehicle parameters to generate verification information indicating whether the driving data collection device is in a correct vehicle;
generate driving data describing how the vehicle is driven responsive to the vehicle parameters;
detect when the driving data collection device is physically connected to and disconnected from the vehicle;
generate a log identifying the connections and disconnections;
generate a data file containing a summary of the driving data, the log, and the verification information and smaller than a predetermined file size, wherein generating the data file comprises;
generating a compressed summary of the driving data;
adding the compressed summary of the driving data to the data file; and
adding raw driving data to the data file to which the compressed summary was added until the data file reaches the predetermined file size; and
output the data file to an external user device by the output interface.

Abstract
Driving data are collected from a vehicle by a device. The device comprises a vehicle interface for interfacing with an on-board diagnostics system of a vehicle and retrieving vehicle parameters of the vehicle from the on-board diagnostics system. The retrieved vehicle parameters include a vehicle identification parameter and driving parameters. The device includes a processor configured to identify the vehicle based on the vehicle identification parameter and determine data describing how the vehicle is driven based on the retrieved vehicle parameters. The device also includes an output interface configured to output the determined data.

8. A non-transitory computer readable storage medium storing computer program instructions executable for collecting driving data from a vehicle, the computer program instructions when executed by a processor causing the processor to:
-
analyze vehicle parameters retrieved from an on-board diagnostics system of the vehicle to generate verification information indicating whether a driving data collection device interfaced with the vehicle is interfaced with a correct vehicle; generate driving data describing how the vehicle is driven responsive to the vehicle parameters; detect when the driving data collection device is physically connected to and disconnected from the vehicle; generate a log identifying the connections and disconnections; generate a data file containing a summary of the driving data, the log, and the verification information and smaller than a predetermined file size, wherein generating the data file comprises; generating a compressed summary of the driving data; adding the compressed summary of the driving data to the data file; and adding raw driving data to the data file to which the compressed summary was added until the data file reaches the predetermined file size; and output the data file to an external user device by an output interface adapted to output data by near field communication. - View Dependent Claims (9, 10)
