Abstract:
1. A device for exchanging data between moving vehicles ( 19 ) comprising a receiving module ( 4 ) for receiving data messages broadcasted from other vehicles ( 19 ) equipped with said device, sensing and processing means ( 6 , 9 , 15 ) for generating vehicle-specific data and a broadcasting module ( 5 ) for broadcasting data messages including said received data and said vehicle-specific data, whereby the device further includes data processing means ( 16 , 17 ) inseparably combining corresponding data from said received data and from said vehicle-specific data to synthesis data messages comprising time stamp data, whereby the broadcasting module ( 5 , 126 ) is adapted to broadcast said synthesis data messages and whereby said data processing means ( 15 , 16 ) include at least one evaluation member ( 66 , 73 , 78 , 79 , 80 , 81 , 82 , 83 ) for evaluating the contribution of received synthesis data messages according to said time stamp data, characterized by further including a route map skeleton generator ( 132 ) and a route map skeleton extractor ( 136 ) for generating route location data extracted from synthesis data messages.
