The integration between the CAN bus system (monitoring the level of the signals) and the fleet monitoring system must be properly designed from the technical and functional point of view. It is not an easy task as the CAN bus specifications depends on firmware versions which are supposed to be the same for a single vehicle production lots but it is not for sure. A survey of the CAN versions is required to track the operated firmware versions as parte of the design activities.
The implementation should be carried out by vehicle production lot. All the vehicles which are similar for typology should be installed in a row: this will allow to optimize the installation costs. Before to start the installation of the first vehicle of each typology the diagram of electrical installation (wiring, connections, etc.) must be provided and agreed between the contractor and the Operator/Authority. After an as-built documentation must be released.
The solutions deal with:
Some of the most relevant examples are the following. Data registered by the vehicle diagnostics monitoring system can be interfaced by on-board fleet monitoring system to associate them to the service conditions (for example operated line). Once a critical event (i.e. water temperature of engine or break temperature over a pre-defined threshold) is detected by the monitoring diagnostics system, a real time notification is sent by the fleet monitoring system (by SMS/e-mail or visualized at Control Centre level) to the allocated staff (vehicle maintenance). The driver is asked to stop the vehicle avoiding the failure. Furthermore the data can be stored in a database and use for statistical analysis about the vehicles performances in the various service conditions. Similarly data registered by the gyroscope (i.e. acceleration) can be associated with the service data registered by fleet monitoring system (i.e. location, operated line, etc.) to carry out analysis of the driver behaviour during the service operation. All this kind of analysis are targeted to better allocate the vehicles, maximizing the time they are operated in optimal conditions and thus reducing maintenance costs.
An appropriate operational procedure must be defined for the management of real-time notifications dealing with events which are critical for the vehicle operation. Usually two kind of options are available:
