And S720, judging whether the vehicle lamp intensity difference is larger than zero.
Specifically, when the difference between the lamp intensities is greater than zero, it indicates that the vehicle is moving toward the sidewalk. When the intensity difference of the vehicle lamp is equal to zero, the vehicle stops moving. When the lamp intensity difference is greater than zero, step S730 is performed. When the vehicle lamp intensity difference is equal to zero, step S740 is performed.
And S730, if the vehicle lamp intensity difference value is larger than zero, the vehicle lamp intensity is enhanced.
And S740, if the automobile lamp intensity difference value is equal to zero, the automobile lamp intensity is unchanged.
The implementation principle of judging whether the intensity of the car lamp is enhanced is as follows: and obtaining a vehicle lamp intensity difference value according to the vehicle lamp intensities at the two moments, wherein if the vehicle lamp intensity difference value is larger than zero, the vehicle lamp intensity is enhanced, and if the vehicle lamp intensity difference value is zero, the vehicle lamp intensity is unchanged, and the vehicle is stopped in place.
