Estudio de la eficacia de frenado de un vehículo con sistema ABS de subcategoría M1 en función de la temperatura de trabajo de las pastillas de freno

Abstract

The objective of this study was to analyze the braking efficiency of a sedan-type vehicle with an ABS, using two brands of brake pads based on their working temperature. An electronic temperature monitoring system was created for a Chevrolet Sail vehicle year 2018 to perform the analysis. An infrared sensor for capturing temperature was adapted to the brake calipers in the front tires of the vehicle for the braking system. These sensors were placed 5mm away from the brake pads. The obtained data through the infrared temperature sensors were processed in real-time employing an Arduino card and then stored in a computer. The investigation was based on the brake system, which involved thermodynamic phenomena caused by the friction between the disc and the brake pads since it does not have a stable behavior. It was observed how the pads temperature influences the braking efficiency of the car with the implementation of the monitoring system. The study used three samples from two brands of brake pads: DBL and BREAK PACK. To obtain brake pad temperature data, five follow-up tests were performed on each selected sample, these tests were performed by ISO 21944:2007. From the obtained results, it can be seen that the changes in temperature of the BREAK PACK brand of brake pads dissipate heat in a better way, thus improving braking efficiency, which demonstrates the difference in marketing costs. It is important to point out that before putting the system into operation, it must be optimally calibrated to avoid possible inconsistencies in data collection.
