Modelling and Characteristics of the Car Emergency Braking Process at Low Frequency Data Logging

The movement of transport vehicles in urban environment is carried out at relatively low speeds and mainly at transient modes of operation of the engines. Kinematic parameters during movement change in relatively narrow dynamic ranges, except for processes during emergency braking. For their research, especially for two-wheeled vehicles, compact devices designed for quick mounting are often used. The conducted research shows that with inappropriate technical characteristics and insufficient frequency of registration of the position of the vehicle, significant deviations from the actual values can be generated. When analyzing the process of emergency braking and especially when studying the period of increase of the braking deceleration to maximum value, it is necessary to determine the requirements for the technical parameters of the device used.
