The instantaneous velocity calculation formula of car pedestrian or vehicle：
V=Δ h/ Δ t
The forward travel distance of car pedestrian or vehicle is between ranging twice：
Δ h=h1-h2
Measurement car pedestrian or the speed formula of vehicle are：
V=Δ h.f
F is reversing radar ultrasonic transmitter look-in frequency.
The movement velocity of car pedestrian or vehicle is measured by above-mentioned formula.
In general urban road, the speed of the vehicles is less than 60km/h, and Class I highway 80km/h is at a high speed
130km/h, about 16.7m/s, Class I highway 22.2m/s, high speed 33.3m/s.
When object is not close in the nearest detection range 30cm of the tailstock after vehicle, in each detection cycle of above-mentioned three kinds of highways
It is interior can travel distance respectively be：
L1=0.005s*16.7m/s=0.0835m
L2=0.005s*22.2m/s=0.111m
L3=0.005s*33.3m/s=0.1665m
About advance 10cm in urban transportation highway, highway about advances 17cm, and being less than tailstock residue can
Detection range, single-chip microcontroller and circuit system working time are negligible, safety in the case of this.
The generation it is possible to prevente effectively from accident is proved by above-mentioned calculating.
