Abstract

A wireless communication device for collecting vehicle on-board diagnostics (OBD) data is disclosed, together with associated methods of handling OBD data in such wireless communication devices. In embodiments, the wireless communication device is arranged to determine when it has been disconnected from the vehicle OBD port and to correct previously stored time-stamped OBD data by synchronizing with an external reference clock signal provided by an external mobile telecommunications device before the corrected OBD data is transmitted to the external device. In other embodiments, the wireless communication device comprises a processor configured to aggregate collected OBD data into risk profile data comprising one or more scalar indicators and/or histogram indicators, and the device is further arranged to store the risk profile data in memory until the device is paired with an external mobile telecommunications device and a data transmission instruction is received. In yet other embodiments, the wireless communication device comprises an accelerometer and a processor configured to determine an orientation of the accelerometer relative to the vehicle based on the OBD data.
