“…A study by Dalibor Viderščak [8] analyzed the relationship between brake pad quality and braking deceleration, highlighting the better deceleration of more expensive pads, especially in extreme conditions. Zdravko Ivanov [9] compared vehicles with and without an anti-lock braking system (ABS), showing that ABS improves safety by allowing faster deceleration and shorter stopping distances. Bojana M. Bošković et al [10] investigated how brake pressure affects component temperature and vehicle performance, finding that higher pressure improves deceleration and shortens stopping distance.…”

This research investigates the feasibility of using smartphones as reliable instruments to measure vehicle deceleration under different conditions and compares their accuracy and reliability with traditional decelerometers. The research was conducted using a passenger vehicle (Audi A6 Avant) on different road surfaces—dry, wet, and gravel—at several speed intervals (30, 50, 70, and 90 km/h). The vehicle was equipped with an XL Meter decelerometer and three different smartphones in different price ranges. Each device recorded deceleration data, which was then analyzed to evaluate accuracy and reliability. The findings show that while the smartphones show promising results on dry and gravel surfaces, their accuracy decreases at lower speeds and on wet surfaces due to the limitations of the sensors in detecting subtle deceleration values. The research also highlights that mid-range smartphones can perform comparably to higher-end models, suggesting that excessive investment in more expensive technology may not be necessary for scientific purposes. However, some differences in measurements are attributed to variations in device mounting and orientation sensitivity. In conclusion, this research supports the potential of integrating smartphone technology in vehicle testing for road safety, although it highlights critical limitations that need to be addressed for standardized use.
