An Adaptive Data-Reduction Protocol for the Future In-Vehicle Networks 2005-01-1540

The demand for drive-by-wire, pre-crash warnings, telematics and many new features will require very high bandwidth from future in-vehicle networks. One straightforward solution to satisfy the bandwidth requirements of future vehicle networks would be to use a higher bandwidth bus or to use multiple busses. However, the use of a higher bandwidth bus would increase the cost of the network. Similarly, the use of multiple busses would increase the cost and the complexity of the wiring. Another option would be the development of a higher layer protocol to reduce the amount of data to be transferred. This paper presents an adaptive data-reduction algorithm based on the CAN (Controller Area Network) protocol.
