Abstract

أصبح استعمال نظام مانع الانغلاق الدوراني (ABS) ضرورة أساسية لرفع مستوى الأمان في المركبات الحديثة، إذ يكمن الهدف الرئيس لهذا النظام في التحكم بالضغط المطبق على الإطار أثناء عملية الفرملة ومنعه من القفل في حالة الضغط المفاجئ والشديد على الفرامل، مما يسمح للمركبة بالتباطؤ بشكل أمثلي ويمنع انزلاقها مع المحافظة على توازنها وعلى قدرة السائق على توجيها والتحكم بها وبالتالي إنقاص المسافة اللازمة لوقوفها.

سنقوم في هذه المقالة بإجراء دراسة رياضية لنظام مانع الانغلاق الدوراني، كما سنقوم ببناء نموذج لهذا النظام باستعمال شبكات بتري الملونة (Coloured Petri Nets)، وسيتم إدخال عملية الاستنتاج الضبابي
(Fuzzy Inference) على القسم الخاص بتحديد قيمة الضغط المطبق على الإطار للاستفادة من المرونة التي يقدمها المنطق الضبابي ثم سيتم إجراء عملية محاكاة للنظام من أجل سرعات ابتدائية مختلفة ومن أجل ظروف طرقات مختلفة (جاف-رطب-حصى). اعتمدنا في بحثنا لإجراء المحاكاة على    CPN Tools.

The use of Anti-lock Braking System (ABS) has become an essential feature to raise the level of safety in modern vehicles; the main objective of this system is to control the pressure applied on the wheel and prevent it from locking in case of sudden and severe braking, allowing the vehicle to slow down in an optimal way and preventing sliding while maintaining its balance and the ability of the driver to steer and control the vehicle and thus reducing the stopping distance.

In this article, a mathematical study of the Anti-Lock Braking system has been applied; we used Colored Petri Nets to build a model of the system; we introduced the concept of Fuzzy Inference on the section used to determine the value of the pressure applied to the wheel, where we took advantage of the flexibility provided by fuzzy logic, and then we conducted a simulation of the systemfor differentinitial speeds and for different road conditions. In this article, we used CPNTools to perform the simulation; this tool was developed by Aarhus University in Denmark and now it is a part of the AIS Group in Eindhoven University of Technology in Netherlands.
