Design of Tire Wear Check System of Car with Laser Sensors

摘要

If tire a little abnormal condition, tire is important one of components in which driver and passenger was effected safety. But there can be a variety the tire problem, there will generally be divided normal wear and abnormal wear. Wear cause of tire is various causes, such as lack of tire pressure, tire side wear, rapid tire wear. The causes has a lot of the case where the multiplicative various causes (such as quality of the tire, driving conditions, air pressure, rotation instruction state, the attachment state of the wheel etc). The general wear is the wear among the car driving, so, you can replace the change of the tire according to the appropriate distance. But, abnormal wear is worn of some part of tire unlike the general wear. Until now, the method to check abnormal tire wear is that a mechanic checks tires with naked eyes and hands to confirm uneven tire wear. However, drivers are embarrassed when facing varied and vague rules of uneven wear, even for each tire. In this paper, it designs a system to check each tire wear by using multiple laser sensors in order to make up for this weakness and overcome the limits of subjective judgment and obtain objective, accurate judgment.
