| Abstract [eng] |
Electronic Stability programme is an active safety system which was introduced by Robert Bosch to improve the stability of the vehicle and prevent the vehicle from an emergency situation such as skidding, understeer, oversteer and rollover accident. With the increase in production of vehicle in developing countries like India, China and introduction of more sports variants by countries like Germany, Italy has lead to increase in number of accidents, so it is of utmost importance that active safety system like ESP must be implemented in all vehicle to protect the passengers from fatalities and reduce the road accidents. To study about the ESP system and analyze the various properties that influence skidding, understeer, oversteer, and rollover specific car model Lamborghini Aventador lp 700 – 4 was chosen and tested by using various regulations in modelling simulation software veDYNA. The testing regulations such as steer step, double lane change, slalom test, circle drive and mu-split was used with varied parameters to know about the limits of the vehicle in various conditions. The graphs generated in the plot - gui of veDYNA software was used to analyze the yaw rate, yaw angle, roll angle, sideslip angle, steering wheel angle and lateral acceleration of the vehicle. The aim of the research is to study about the effectiveness of ESP system using theoretical methods and apply various methods leading to skidding, understeer, oversteer, and rollover using vehicle simulation software veDYNA which is linked with Matlab/Simulink interface. |
