Investigation Of Braking Deceleration In Vehicle

An experimental study of the process of stopping a car was performed. Tests have been carried out to determine the duration of the periods for increasing the braking deceleration to its maximum value (t3) and for the movement of the vehicle with maximum braking deceleration (t4). The values of the corresponding decelerations during these time intervals are determined. The results of the research show that the increased time during the first period determines a longer distance traveled and a correspondingly lower value of the average braking deceleration during the period immediately after the impact on the brake pedal. For vehicles without ABS, the initial speed at which the vehicle approaches the interval t4 is lower due to the longer duration of the period t3. To this increase in time and distance traveled is added the movement of the vehicle in the next period, in which a smaller value of the average maximum braking deceleration is also registered.
