Abstract

A system and method of transmitting vehicle information from a vehicle to a server across an external network. A vehicle bus connector module is plugged into a vehicle bus through the vehicle'"'"'s vehicle bus connector. The vehicle bus connector module is also communicatively connected to a personal communications device. Vehicle information is collected from the vehicle bus and combined with information captured by the personal communications device to form a driver log. The driver log is transmitted to the server via the external network.
