EFFECTIVENESS OF BASIC DISPLAY AUGMENTATION IN VEHICULAR CONTROL BY VISUAL FIELD CUES

The effectivenes of different basic display augmentation concepts (fixed reticle, velocity vector, and predicted future vehicle path) for remotely piloted vehicles (RPV) controlled by a vehicle mounted television camera is investigated. The task is lateral manual control of a low flying RPV along a straight reference line in the presence of random side gusts. The man-machine system and the visual interface are modeled as a linear time-invariant system. Minimization of a quadratic performance criterion is assumed to underly the control strategy of a well-trained human operator. The solution for the optimal feedback matrix enables the explicit computation of the variances of lateral deviation and directional error of the vehicle and of the control force that are used as performance measures. The results show that the effectiveness of the display aids strongly depends on the vehicle dynamics and the spectrum of the disturbance.
