MOTOR VEHICLE ENERGY-SAVING ASSISTANCE SYSTEM

摘要

A motor vehicle energy-saving assistance system which helps to save energy and optimize emissions. An electronic device may be permanently installed in the vehicle, or a portable computer containing an energy-saving program may be used. The device or program exchanges data with several vehicle control devices. The vehicle control devices carry out specific driver-assist or vehicle functions and the further data channel provides a connection between the device or the portable computer and the vehicle control device(s). At least one unidirectional wireless, inductive or capacitive data transmission is enabled. A driver display device is controlled by the energy-saving program and the energy-saving program determines the actual condition of the vehicle and the estimated future condition in order to calculate the energy-saving measure(s). A motor vehicle equipped with an interface which provides access to the vehicle onboard bus system is also described.
