Patent ID: 11398115

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. The device comprises a connector for connecting the device to an OBD port of a vehicle to receive OBD data; a processor configured to continually aggregate the OBD data and/or acceleration data from an acceleration sensor into risk profile data during a journey made by the vehicle; a memory for storing the latest risk profile data for the journey; and a wireless transceiver for transmitting the stored risk profile data to an external mobile device during the journey. The processor is further configured to determine an engine state of the vehicle and to detect when the vehicle begins and ends a journey based on said determined engine state and OBD data relating to vehicle speed and/or engine revolutions, and to cause the stored risk profile data to be deleted from the memory upon detection that the vehicle has begun a new journey.
