Take the blind area of the rear of vehicle and side also and may include: angle of turn parameter, the vehicle geometric dimension according to vehicle
It is blind that parameter and vehicle wheel base parameter calculate the visual field positioned at the vehicle side and rear of the vehicle under state of rolling backward
Area.
Under normal conditions for the vehicle determining for one, the property parameters of its own are fixed, such as size
Parameter, wheel base parameter.Therefore, for aforesaid way two and mode four, the blind area of vehicle be can be in advance really
It sets, for example, vehicle is on startup, the blind area of the vehicle front and height, the height of seat, the length of headstock of vehicle body
Degree and the stature of driver have relationship, since the height of its vehicle body, the length of headstock are all true for a vehicle
Fixed, the height of seat can be adjusted by driver, and the stature of driver is also not exclusively the same, thus the vehicle on startup for
The blind area of the vehicle front might have little bit different for different drivers, but in practical applications for the ease of more
The fast danger zone for preferably determining vehicle, can choose an average stature and be calculated, therefore determining for one
For vehicle, it is believed that its on startup front blind area be it is determining, specifically may refer to shown in Fig. 3.Vehicle is straight
When row, blind area other than it may include the blind area of vehicle front, can also include vehicle side the visual field it is blind
Area, the blind area of vehicle front mainly with when vehicle launch in front of blind area it is identical, can all be due to Vehicular body front
