Specifically, when the difference in lamp intensity is greater than zero, it indicates that the vehicle is traveling toward a sidewalk. And when the difference value of the intensity of the car lights is equal to zero, the car is stopped. When the lamp intensity difference is greater than zero, step S730 is performed. When the lamp intensity difference is equal to zero, step S740 is performed.
And S730, if the intensity difference value of the car light is larger than zero, the intensity of the car light is enhanced.
S740, if the car light intensity difference value is equal to zero, the car light intensity is unchanged.
The implementation principle for judging whether the intensity of the car lamp is enhanced is as follows: according to the car light intensity at two moments, obtain car light intensity difference, if car light intensity difference is greater than zero, represent car light intensity reinforcing, if car light intensity difference is zero, represent car light intensity and not change, the car is stopped in place.
