Abstract

Methods and systems for maintaining telematics data. The system includes a standard vehicle. The standard vehicle includes one or more sensors configured to detect telematics data, a memory configured to store a blockchain associated with the standard vehicle, an electronic control unit (ECU) configured to update the blockchain associated with the standard vehicle with the detected telematics data, and a transceiver configured to communicate the blockchain to one or more other vehicles. The system also includes a collection vehicle. The collection vehicle includes a transceiver configured to receive the blockchain from the standard vehicle, and communicate the blockchain from the standard vehicle to a network to update a distributed record of the blockchain associated with the standard vehicle.
