Estimation of Brake Pad Wear Using Fuzzy Logic in Real Time

Abstract

Brake pad components are important in two-wheeled vehicles because they concern the driver's and others' safety. Brake lining wear is an unavoidable phenomenon. This is because of the concept of braking, which involves bringing two things into contact with each other such that they press against each other and rub against each other. Brake pads that have not been replaced make the brakes unable to work normally, so the potential for accidents is even greater. One of the factors causing the problem is negligence and ignorance of the condition of the ream linings, which should be time for the change. This paper proposes a tool that can estimate the condition of the brake pads based on the level of wear in real-time using the fuzzy logic method. Fuzzy logic will estimate the degree of wear of brake pads based on speed, brake fluid pressure, and braking duration parameters. The type of brake used in this paper is the type of disk brake used on two-wheeled vehicles. The test is not carried out or applied to two-wheeled vehicles but is applied to brake pad wear test equipment that works like a two-wheeled vehicle.  Based on the test results, the fuzzy logic implanted into the Arduino microcontroller can provide information on the estimated condition of the brake pads on LCDs in real time based on fuzzy set datasets obtained through experimental tests. Based on the experimental results, the brake lining wear test was carried out for 30 minutes with a pressure of 10 and 17 psi. The results showed that the thickness of the brake linings decreased by around 21.66% and 26.68%, respectively.
