This automated inspection alarm system carries out real-time detection to the barrier around the in-process vehicle of traveling and the condition of the highway section that the car is about to go, improves the unmanned factor of safety of car, makes the travelling comfort of car in-process better.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
