Degree take around 2.8~4.8s, and in vehicle travel process driver emergency braking manipulation process, can be divided into perception, decision,
Operation executes, brake works to the stages such as vehicle stopping, chinese national standard " JTG D20-2006 Route Design rule
Model " in will make the accumulated time that consciousness-reaction-braking comes into force go bail for keep 2.5~3s of value calculating.To guarantee vehicle driver
There is time enough to take measures after observing warning light flashing.In addition Doppler radar is also resided in along antenna array normal side
It is best to the detection effect to pedestrian.
Preferably, microwave remote sensor is multiple target Doppler radar, using Doppler effect come the position of detecting pedestrian
With the radar of speed of related movement.
Specifically, judgement is compared to pedestrian using Doppler radar, so that whether obtain has pedestrian to pass by microwave
The search coverage of sensor, and judge the direction of motion of pedestrian.When warning system work, when there is pedestrian to enter entrance to a lane, it is used for
The sensor of pedestrian detection can detect pedestrian, at this moment will cause system wrong report.Using Doppler radar to pedestrian in this system
Consecutive tracking obtain the direction of motion of pedestrian carried out by light flash and is warned by the pedestrian moved towards entrance to a lane, for towards in lane
The pedestrian of movement, then warn without light flash.
