Background technology
Speed limit be in daily life often in contact with to concept.Vehicle travel on road, its maximum travel speed by
The restriction of many factors, in simple terms including following aspect：
1. the limitation of extraneous objective condition.Such as：The factors such as road grade, wind-force, weather；
2. vehicle self-condition is limited.Such as：Time limit speed etc. is sailed at the beginning of vehicles dynamic performance, specified speed, vehicle；
3. the restricted speed set by control of traffic and road department.Such as：Speed Limitation on Freeway, traffic light intersection speed limit etc.；
4. human factor.Such as：Unit of operation voluntarily defined highest speed of operation, load；
5. driver's subjectivity behavior.The highest that driver travels with the parts operational control vehicle such as gas pedal and braking
Speed.
In above factors, the subjective behavior of human pilot is to influence the main factor of vehicle maximum travel speed,
It is also to influence the most immediate cause of traffic safety.Driver is caused due to the difference of personal quality, driving efficiency and psychological quality
Hypervelocity behavior happens occasionally, and the main cause as pernicious traffic accident, just so-called " ten accident nine times fast ".By the above
Analysis is understood：Such as limit the max. speed of vehicle make its it is not super it is various under the conditions of limitation speed, for vehicle driving safety, drop
Low traffic accident incidence, reduces record of driving against traffic regulations, reduction vehicle operating cost, and tool is of great significance.However, arriving
So far except a small number of vehicles dispatch from the factory period setting maximum travel speed limitation in addition to, it is more in the case of can only by drive
The subjective behavior of member controls highest speed of operation of the vehicle on different roads, and this energy requirement, work to driver is strong
Degree etc. can all produce certain influence, be unfavorable for traffic safety.Therefore, driver how is avoided because artificial speed limit is operated and produces
Fatigue, uncomfortable and error turn into the problem of needing to solve.
