Abstract

A vehicle having a driver statistic system for interfacing with a network includes a wheel speed sensor, an engine control unit, network interface hardware for communicating with a network, and an electronic control unit communicatively coupled therebetween. The electronic control unit includes a processor and memory storing a computer readable and executable instruction set. When the instruction set is executed by the processor, the electronic control unit processes sensor signals received from the wheel speed sensor and the engine control unit to determine fuel consumption of the vehicle. The electronic control unit transmits a vehicle status signal to the network interface hardware, where the vehicle status signal is indicative of the fuel consumption of the vehicle. The network interface hardware transmits the vehicle status signal to the network. The network interface hardware further receives a vehicle performance signal from the network indicative of a driver performance ranking.
