One solution is to use the control device described herein, in conjunction with one or more mobile devices within the vehicle, to determine location of such mobile devices and then to determine the likely driver of the vehicle based upon such location determinations. Armed with this information, it is then possible for the control device or a software application on the mobile device of the driver to communicate vehicle status information and driver information to the carrier network, which can then intelligently send back a suitable signal to cause the mobile device to go into blocking/auditing/scoring mode. Alternatively, the carrier itself could impose a block, at least on cellular voice and data communications controlled by the carrier, to prevent such functionality until the control device or mobile device sends a suitable signal indicating that the vehicle is no longer being driven by the user of the mobile device and/or that the mobile device is no longer located in the driver space of the vehicle. It will also be appreciated by those of skill in the art that, armed with the information concerning who is driving the vehicle, it is then possible for the control device or a software application on the mobile device of the driver to communicate vehicle status information and driver information to a remote application server, which can then intelligently send back driver-specific data and information that can be used by software applications installed on the mobile device, for purposes other than distracted driving prevention.
