1. A method for sending vehicle data from an in-vehicle control unit to a processing center, comprising:
- collecting the vehicle data;
determining whether to transmit the vehicle data to a processing center over a first transmission network or a second transmission network;
transmitting the data to the processing center over the first transmission network using a first modem if the determining step determines that the vehicle data should be transmitted over the first transmission network; and
transmitting the data to the processing center over the second transmission network using a second modem if the determining step determines that the vehicle data should be transmitted over the second transmission network.

Abstract
A multi-mode in-vehicle control unit (ICU) contains a plurality of modems. Each modem allows the multi-mode ICU to transmit vehicle data over a different kind of transmission network. Exemplary transmission networks include wireless data networks, cellular telephone networks and satellite networks. Vehicle data is collected. The multi-mode ICU selects one of the modems for transmission of vehicle data to a processing center. Priorities can be assigned to the transmission networks and or modems to control order the transmission network selection process.
