CAN Message Filter Algorithms for Remote Diagnostics of Vehicles

Remote diagnostics means the substitution of regular in-place diagnostic processes with methods based on telecommunication networks. This includes online monitoring of the vehicles' On-Board systems. Those corporations run on logistics, transportation, using these devices experience in order to increase reliability and decrease down-time of their vehicles. In our paper we introduce our research results on how to make possible remote diagnostics of vehicles through a GSM system. For remote diagnostics through GSM network, it is necessary to reduce the amount of data to be transmitted. We explain our implemented filter algorithms developed into a programmable controller for the reduction of communication load.
