Abstract

Remote monitoring and control of a motorized vehicle is performed using a communications and control hub connected directly to an onboard diagnostic port of the vehicle. An auxiliary onboard diagnostic port is provided to permit technicians to perform diagnostics on the vehicle. All vehicle monitoring and control is effected without an auxiliary wiring harness. The communications control hub is particularly useful for fleet management and dispatch systems.
