The gateway is a translator used between two systems that differ in communication protocol, data format or language, or even in an entirely different architecture. Instead of the bridge simply communicating the information, the gateway repackages the received information to accommodate the needs of the destination system. In the current intelligent automobile system, generally adopt redundant system to carry out the safety guarantee to the system, redundant system aim at generally: for insurance, two sets of hardware, software or design and the like which are also independently configured are adopted, so that when one set of system fails, the other set of system can be started immediately to replace work, and the effect is similar to that of an actor. A single system may operate at a high failure rate, but after redundancy measures are taken, the reliability of the system can be greatly improved immediately without changing the internal design.
