Description
With the increase of electronic content in automobiles and, despite of the great advances in communication buses, wiring weight is continuously increasing weight. Today, the gross weight of the wiring harness using a conventional electric wire is about 30 kg/car. TRANNSMITE will provide a wireless energy and data transfer systems with improved efficiency and reliability to be used in the interior of a car. The systems will allow the incorporation of new functions without increasing the car’s weight. TRANNSMITE will show it is possible to include multiple functions (sensors and actuators) into a car seat without electrically connecting it to the car body. TRANNSMITE will provide benefits at two levels: - Automotive companies that will be able to add new functions without increasing the car weight. - Car users will see an improved comfort and safety without compromising its fuel efficiency. The knowledge achieved in TRANNSMITE will have other potential applications in the automotive market (for charging an electric vehicle) or for other markets (industrial sensors or consumer electronics).
Summary of project results
Wiring sensors installed in rotating parts s( wheels or removable parts (seats) can be unfeasiblel. Several solutions have been studied to provide an electrical connection for removable seats, but these seat assemblies require a user to manually disconnect /uncouple electrical connectors/ contacts when it is desired to remove the seat and then to reconnect the electrical connectors / contacts when the seat are installed in the vehicle. Automatic connection and disconnection systems have also been studied, but they result in very complex solutions that add a significant weight and requiring important energy consumption to its manufacturing process, increasing CO2 footprint of the system and making the weight reduction achieved by using a lightweight structure not being reflected in the final system. Euro NCAP evaluates cars with regards to safety giving a maximum of 5 stars. Not being able to integrate safety devices in the seats limits the maximum attainable punctuation.
