What factors should be considered in the system design of the car?

2 Oil, water, smoke, dust and the effects of chemically corrosive substances that may be encountered.

3 mechanical vibration, bumps, impacts.

4 electromagnetic compatibility issues.The release of work (including sound, light, electromagnetic, oil and gas) must meet environmental requirements, but also take into account the handling of parts and vehicles when they are scrapped.

6 Possible failures and possible misoperations, such as reverse power connection, wire drop, short circuit/open circuit, friction, etc., should be as small as possible.The following factors should also be considered in the on-board network system: 1 Electrical and mechanical characteristics of the joints of the nodes and the bus and the number of connectors.2 Network system and application system evaluation and performance testing methods.3 fault tolerance and failure recovery issues.4 Real-time control of the time characteristics of the network.
