Property conclusion, its test result is easily affected by factors such as field experiment environment and the bit error rates.
Secondly, in the selection of communication apparatus, domestic research unit or automobile vendor mainly adopt import equipment, and
Secondary development is carried out on equipment, the channel resource when communication quality to equipment itself and many vehicles are assembled is fought for lacking effectively
Analysis means.
3rd, the record data integration relative loose to vehicle behavior, such as produced data in vehicle travel process,
As video, signal of eating dishes without rice or wine, frequency spectrum takies, and driving behavior and these behaviors correlation in time is difficult to integrate.

Model machine in producer.However, this kind of system be unsatisfactory for the needs of car networking vehicle testing.The test of car networking vehicle is except closing
Outside note vehicle driving information itself, the information of vehicle communication is focused more on.Not automobile vendor or supplier arrogate to oneself radio communication
Long field, lacks integration ability for system.
Polytype sensor is comprised, the data of sensor is acquired by multiple systems, in data knot in test
Structure, in the sampling period, recording mode aspect lacks effectively to be unified.
Due to lacking the record of data, the analysis that single experiment can be carried out is limited, carries out qualitative analysis rather than quantitation
Analysis, such limit decision needs more repeated experiments, produce more experimental phenomenas and result is summarized,
It is difficult to analyse in depth data produced by experiment each time it is difficult to the reason more scientific mode, research experiment phenomenon behind.
To sum up, there is following defect in existing metering system：Experimental facilities is various, but cannot collaborative work；Data record lattice
Formula disunity is it is impossible to be integrated into a system；Being repeated several times property of dependence is tested, and leads to the wasting of resources.
In view of this, nowadays in the urgent need to designing a kind of new metering system, to overcome existing metering system to exist
