Modern vehicles like buses, coaches, trucks and other commercial vehicles as well as ships and off-highway vehicles like construction and farming machines have many functions directly controlled by computer systems that also need to communicate with the outside world.
As environments are harsh, the computers must be very robust and require e1 automotive certification. In addition to robustness, small footprint solutions are a must in narrow driver cabins.
Control computers for vital functions are typically networked by fieldbuses like CAN bus inside the vehicle. Communication computers are mostly based on standard Ethernet, while the outside is connected using different wireless standards (GSM, GPRS, Edge, UMTS, HDSPA, LTE, WLAN).
Dynamic information systems - whether on board a bus or ship - inform passengers on the current traffic and weather conditions, tour destinations and delays. Access points are required for Internet access or connection to the telephone network. Content servers and video recorders may store movies or camera data from surveillance systems.
Precise piloting of construction or agricultural machines (even at night) may require control of cameras, reception of GPS data for navigation, communication with other drivers etc., with all kinds of data and diagnosis results transmitted and exchanged with the company office or farm house.
