Automotive safety system
Project definition
In this project we are working on a wireless vehicle to vehicle communication, which should improve the active safety on the roads. The main goal is to prevent the mass car accidents with the distributed warning system. For example ff there is an obstacle on the road, the first vehicle which makes a special maneuver (hard breaking, fast trajectory change...) immediately starts to transmit a warning signal which is then distributed to other nearby vehicles and forwarded by them to cars a few kilometers ahead the obstacle. Every vehicle is a self-standing function unit. It measures its own position and compares it with position of other units in range. Then it decides which messages are important and if there is a related action for them. The functionality of the system is based on a quite large amount of wireless nodes.
The project is devided into three nain parts:
- communication protocol
communication is based on a research in this paper, a model was made and verified with the UPPAAL modeling and verification tool.
finished (February 2006)
- hardware development
in current days we have two wireless T-Mote Sky modules and we have developed GPS/Acccelerometer boards. In further work we assume our own control unit especialy widening the system for CAN communication
working on
- software development
the communication between GPS/Acc. board and T-mote Sky modules is being finished with a testing application.
