Claim:
1. An intelligent control method for headlights of an automobile, comprising: setting a low beam threshold of ambient light intensity a high beam threshold of ambient light intensity a tunnel entry threshold of rate of decrease of ambient light intensity and an automobile meeting threshold of rate of increase of ambient light intensity; detecting a current ambient light intensity at a first interval of time in an automatic control mode, and controlling a turning on or off of the high beam lights and low beam lights according to an on status or off status of the high beam lights and low beam lights, the current ambient light intensity, and the a current rate of increase or decrease of ambient light intensity; wherein the controlling comprises, while operating the automobile in the automatic control mode with both high beam lights and low beam lights off: if the current ambient light intensity is less than the low beam threshold, comparing a first current rate of decrease of ambient light intensity as measured under a condition that both the high beam lights and low beam lights are off with the tunnel entry threshold; and if the current rate of decrease is less than the tunnel entry threshold, activating a night traveling mode wherein the low beam lights are all on; and if the current rate of decrease is greater than the tunnel entry threshold, activating a tunnel traveling mode wherein the low beam lights are all on.
