Methods of operation for plug-in wireless safety device

摘要

An aftermarket plug-in safety device that allows a vehicle to communicate with other vehicles or infrastructures in a V2X communications system. The device includes a radio for transmitting and receiving signals and a GPS receiver for receiving GPS signals and providing vehicle position data. The device also includes a memory for storing digital security certificates and vehicle application data and a processor configured to be put in electrical communication with a vehicle CAN bus. The processor receives vehicle location signals from the GPS receiver, files from the memory and signals from the radio and providing signals for transmission to the radio. The processor identifies the vehicle that the plug-in device is coupled to and provides data on the CAN bus identifying the device. The processor also performs self-configuring operations based on type of vehicle, access to vehicle systems and location of the vehicle.
