AUTOMATED STEERING CONTROL IN VEHICLE-FOLLOWING COLLISIONS

The work reported in this paper contains studies that combine the modeling of vehicle dynamics and the application of control in vehicle collisions. A controller was incorporated into the vehicle collision and dynamic model that allowed the application of steering efforts immediately following a collision. Controller gains and other parameters were varied to investigate the effectiveness of control efforts in stabilizing vehicle trajectories. Of particular interest is the feasibility of maintaining the path of vehicles when an impact causes a strong disturbance to the motions of these objects. This study was conducted with a combination of a collision model and a vehicle dynamics model, SMAC (Simulation Model of Automobile Collisions). SMAC allows the longitudinal and lateral movements of vehicles as well as the rotational motion about the vertical axis of vehicles on a horizontal plane. If a contact between vehicles is detected, the collision phase is analyzed. The external forces can be applied either at the tire/road interface or between the vehicles. Lane tracking is the primary objective of the steering control efforts intended in collision scenarios discussed in this paper
