Controller area network (can) based on anti-lock braking system (abs) / Nur Amirah Mohamad Mohayadin
Tujuan utama penyelidikan ini adalah untuk meningkatkan rangkaian komunikasi Anti-Lock Braking System (ABS) dengan mengubahsuai bas Controller Area Network (CAN) menggunakan MATLAB Simulink. ABS adalah sistem kawalan keselamatan yang penting dalam kenderaan. Oleh itu, rangkaian komunikasi dalam sistem mestilah dapat menghantar mesej dalam tempoh masa yang terhad. Konfigurasi rangkaian yang berbeza dari model simulasi CAN dengan 3 nod, 10 nod dan 70 nod dibina untuk membandingkan dan menganalisis prestasi dari segi kelewatan paket dan jitter. Peningkatan bilangan nod CAN akan merendahkan prestasi rangkaian CAN. Oleh itu, model CAN dengan 3 nod mempunyai kelewatan paket purata terendah sebanyak 0.1151 ms dan jitter purata terendah sebanyak 13.01 μs. Seterusnya, kaedah pengedaran model CAN kemudian diubah suai untuk paket data input untuk meningkatkan prestasi permohonan masa nyata. Dua jenis kaedah pengedaran digunakan untuk membandingkan prestasi dengan taburan asal iaitu taburan Weibull dan taburan Beta. Walau bagaimanapun, model CAN yang diubahsuai dengan kaedah pengedaran Beta mempunyai hasil yang lebih baik daripada pengedaran Exponential asal dan pengedaran Weibull yang diubahsuai. Akhir sekali, model sistem kawalan ABS dilaksanakan dalam model rangkaian CAN yang asli dan diubahsuai sebagai sistem aplikasi. Kelewatan paket purata pengedaran Beta model CAN dengan aplikasi sistem kawalan ABS ditingkatkan sehingga 27.53%, sementara, jitter purata meningkat sehingga 76.93% berbanding dengan model aplikasi asal. Dari penyelidikan, model CAN yang diubah suai dengan penggunaan sistem kawalan ABS lebih konsisten dan boleh diharap berbanding dengan model aplikasi CAN yang asal. _______________________________________________________________________________________________________ The main purpose of this research is to improve the communication network of Anti-Lock braking System (ABS) by modified the Controller Area Network (CAN) bus in MATLAB Simulink. ABS is an important safety control system in vehicles. Therefore, the communication network in the system must be able to transmit the message within a bounded time. Different network configurations of CAN simulation models with 3 nodes, 10 nodes and 70 nodes are constructed to compare and analyze the performance in terms of packet delay and jitter. Increasing number of CAN nodes will degraded the performance of CAN network. Therefore, CAN model with 3 nodes has the lowest average packet delay of 0.1151 ms and lowest average jitter of 13.01 μs. Next, distribution methods of CAN models are then modified for data packets input to improve the performance of the real-time application. Two types of distribution method are used to compare the performance with the original distribution which are Weibull distribution and Beta distribution. However, modified CAN models with Beta distribution method have better results than original Exponential distribution and modified Weibull distribution. Lastly, ABS control system model is implemented in original and modified CAN network models as application system. The average packet delays of Beta distribution CAN models with application of ABS control system is improved up to 27.53 %, while, the average jitters are improved up to 76.93 % compared to the original application model. From the research, modified CAN models with application of ABS control system are more consistent and reliable compared to the original CAN application models.
