Development of firing on board system of an armored vehicle using Active Front Wheel Steering system

Abstract

The aim of this paper is to minimize the unwanted disturbance occurred in a wheeled armored vehicle during firing. An unwanted yaw moment occurred at the Center of Gravity (CG) of the armored vehicle caused by the impulse force generated during firing. This firing force tends to create instability conditions for the armored vehicle during firing. Therefore, an active safety system known as Active Front Wheel Steering (AFWS) is implemented to provide steering correction as a counter action of the firing disturbance and return the armored vehicle back to its initial travelling direction after firing moment. The AFWS is developed based on various control strategy known as yaw rate feedback, sideslip feedback and firing moment estimator feedback with summation moment reference (SuM-FME) controls. Each control strategies are evaluated using two types of vehicle speed, 40 and 60 km/h in order to study the performance of AFWS while in dynamic condition. A suitable control strategy is selected as the firing on board system (FoBS) to enhance the dynamic performance of the armored vehicle during firing.
