5、 Security configuration test link

In the front and rear vision test of the vehicle, all the seats in the vehicle have been adjusted to the lowest state, and the measured data have some deviations from the driver's normal use, which is only for reference.

In the link of testing the front view, we used the pile barrel with a height of 70cm as the reference object, and then adjusted the distance until the top edge of the pile barrel can be seen in the main driver's seat. After the test, the final measured data of pile barrel and vehicle head is 4.5m, which is at the downstream level among the tested vehicles of the same level.

In the rear view test, the pile bucket is still fixed, and then the vehicle is moved until the upper edge of the pile bucket can be observed. According to the actual measurement, the rear vision distance is 25.5m, which is also at the downstream level among the tested vehicles of the same level. It can be seen that the front and rear blind areas of the car are too large.

When testing the field of vision of the exterior rear-view mirrors, first let the tester stand at 10m vertically from the left and right rear-view mirrors, then start moving to the left and right until they appear at the outermost edge of the rear-view mirrors on both sides, and measure their transverse distance. Then, the included angle angle of the rear-view mirror's field of vision can be obtained through formula calculation. The larger the angle, the smaller the blind area of the rear-view mirror; otherwise, the larger the blind area of the rear-view mirror.

The exterior rear-view mirrors on both sides of the evaluation vehicle are ordinary lenses without hyperbolic lenses. The measured result of the left exterior rear-view mirror is 25.2 °, which is at the average level among the tested vehicles of the same level. The right exterior rear-view mirror is 17.2 °, which is at the middle and downstream level among the tested models of the same level.
