Remote Assistance

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 our HY-eVision² operator terminals 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 also be loaded to the internal memory of a remote display controller, or to a connected Log & Load device.

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 also displayed on the remote user's PC depending on language selection.
