Abstract

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.

Claims

1-9. -9. (canceled)

10. A motor vehicle energy-saving assistance system which assists the driver in saving energy or in optimizing emissions, comprising:

an electronic device configured to implement an energy-saving algorithm and which exchanges data, over a further data channel, with a plurality of electronic vehicle control units which communicate over at least one data bus, wherein the plurality of vehicle control units carry out specific driver assistance or vehicle functions, and wherein the further data channel makes available a connection between the electronic device and one or more of the vehicle control units, wherein said connection permits at least a unidirectional transmission of data, and

at least one driver display device which is actuated by the energy-saving algorithm,

wherein, in order to establish an energy-saving measure or measures, the energy-saving algorithm determines the current state of the vehicle and the expected future state thereof.

11. The system as claimed in claim 10, wherein the further data channel facilitates wireless, inductive or capacitive transmission of data.

12. The system as claimed in claim 10, wherein the specific driver assistance or vehicle function or functions is/are one or more functions from the group of:

engine control, vehicle control, brake control, anti-lock brake control, electronic stability control, adaptive cruise control, navigation system, satellite-supported determination of position, and cartographically supported navigation systems.

13. The system as claimed in claim 12, wherein the cartographically supported navigation system uses current map data from mobile radio networks.

14. The system as claimed in claim 10, wherein the electronic device and/or the at least one driver display device is/are embodied as a mobile device or mobile devices, wherein the mobile device or devices is/are galvanically, inductively or capacitively coupled to the data bus via the additional data bus in such a way that the mobile device or devices are easily connectable to the bus.

15. The system as claimed in claim 10, wherein said system performs at least one or more of energy-saving measures including intervention into the speed control of the vehicle by braking and/or accelerating.

16. The system as claimed in claim 10, wherein said system performs at least one or more of energy-saving measures including intervention into a vehicle operated pedal characteristic, a steering characteristic, and/or a braking characteristic.

17. The system as claimed in claim 10, wherein said system performs at least one or more of energy-saving measures including intervention into the distance to be set by an adaptive cruise controller and/or haptic/optical display of a proposed measure for the vehicle driver.

18. The system as claimed in claim 10, wherein the electronic device configured to implement the energy-saving algorithm which controls the system is embodied in a mobile computer.

19. The system as claimed in claim 18, wherein the mobile computer is coupled to the data bus.

20. The system as claimed in claim 12, wherein the brake controller comprises a recovery means for recovering braking power in an accumulator.

21. The system as claimed in claim 10, wherein the energy-saving measure or measures is/are optionally carried out independently.

22. The system as claimed in claim 10, wherein the energy-saving measure or measures is/are selected by the driver.

23. The system as claimed in claim 10, wherein the electronic device is permanently installed in the vehicle.

24. A motor vehicle, said motor vehicle equipped with an interface for an energy-saving assistance system, wherein said interface provides access to the vehicle-internal bus system by an energy-saving assistance system.

25. The motor vehicle as claimed in claim 24, wherein the interface is a radio interface.

26. The motor vehicle as claimed in claim 24, wherein the interface comprises a safety device which prevents non-enabled use of the interface.
