Remote Assistance for Mobile Applications |
||
Remote access to vehicle data such as error logs or run-time parameters speeds up and simplifies vehicle diagnosis and significantly reduces maintenance costs and downtime. Remote Assistance provides a flexible and easy-to-use solution for enhancing Vision display controllers with remote assistance support. The solution uses standard GSM modems for remote operation and Ethernet for local operation in order to connect a self-configuring PC-based service tool with a vehicle control system. In order to make best use of the limited GSM bandwidth, the remote assistance solution uses compression and dynamically adjusts the amount of transmitted data based on the currently visible parameters in the user interface. The PC software synchronizes with the vehicle's control unit by downloading and interpreting an XML configuration file that is stored on the display controller. Run-time parameters can be monitored and modified over this connection. In addition, files can be loaded to the internal memory of a remote display controller, or to an optional remote-connected dual memory stick supporting USB and RS-232 interfaces. With the included multi-language support it is possible to define multiple versions of all descriptive texts in the configuration file for different languages, which are then displayed in the PC application depending on the currently selected language. |
