Comparative Analysis of Vehicle Deceleration Measurement Devices

Analysis of vehicle deceleration as one of the key parameters of vehicle safety and performance, and the method of determining it, is a very common topic. This paper provides a theoretical analysis of deceleration as one of the vehicle parameters, and emphasizes various applications of this parameter. Deceleration as a parameter is not only important when determining the vehicle's braking efficiency but its analysis can also provide additional interesting information. The key item is the correct determination of the deceleration under experimental conditions. Thus far, inertial devices for measuring deceleration,which are quite impractical for handling, maintaining and analyzing the measured data, have been used the most. In this paper, a comparative analysis of this device is performed with new devices for measuring deceleration based on GPS and MEMS (Micro Electro Mechanical System) technology. The result of this research provides an answer as to whether the use of devices based on new data acquisition and processing technologies is justified, or whether outdated technologies should still be used.
