Abstract:
This work introduces a new mathematical model that can be utilized for designing control systems for improving vehicle stability during cornering maneuvers. The mathematical analysis aims at deriving empirical relations between control parameters like normal load, wheelbase length and tire friction (Tractive/Braking and lateral forces) and derive a ‘stability optimization function’ for a closed loop stability control system. This approach towards a new generation of stability control systems can be useful in simulating more realistic (Transient-state) driving conditions through tire friction models within the linear regime and at the same time incorporating the driving techniques followed by professional race drivers, which shall assist in generating operational modes for stabilizing the vehicle at the time of maneuver. The mathematical model takes into accounts the combined effect of longitudinal (Braking) and lateral forces (Steering) of the wheels which is traditionally used to increase the grip of the wheels and assist the system to optimize vehicle load longitudinally through weight transfer techniques as characterized by its ‘stability optimization function’.
