WIRELESS COMMUNICATION DEVICES
First Claim
1. A wireless communication device for collecting vehicle on-board diagnostics (OBD) data, the device comprising:
- a connector for connecting the device to a vehicle OBD port to receive OBD data and power;
a processor and real-time clock powered by the connector and arranged to apply time stamps to the OBD data;
a memory for storing the time-stamped OBD data; and
a wireless transceiver for pairing with an external mobile telecommunications device to wirelessly transmit OBD data,wherein the wireless communication device is arranged to determine when it has been disconnected from the vehicle OBD port and to correct the time-stamped OBD data by synchronising with an external reference clock signal provided by the mobile telecommunications device before the corrected OBD data is transmitted to the external mobile telecommunications device.

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 synchronising 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.

39. A method for correcting vehicle on-board diagnostics (OBD) data collected by a wireless communication device that does not have an internal power supply, the method comprising:
-
receiving OBD data and power from a vehicle OBD port; processing the OBD data by applying time stamps using a real-time clock internal to the device;
storing the time-stamped OBD data in a memory;determining when the device has been disconnected from a vehicle OBD port; requesting synchronisation with an external reference clock signal when the device is wirelessly paired with a mobile telecommunications device; calculating a time correction factor; and correcting the stored time-stamped OBD data before the corrected OBD data is transmitted to the external mobile telecommunications device. - View Dependent Claims (40, 41, 42, 47)
