ABSTRACT:
A heads-up display system for a road vehicle, comprising sensors for detecting the motion related parameters of the vehicle, computer for predicting the motion of the vehicle, and a heads-up display for displaying information within the view of the driver of the vehicle. The computer converts the predicted motion of the vehicle into an image display on the heads-up display so as to permit the driver to see the image display in a certain relationship with his view as he looks ahead of the vehicle. Thus, the driver can gain useful information on the motion of the vehicle such as limit turning trajectories and braking distances so that he can operate the vehicle more easily and more sensibly than was possible heretofore. The heads-up display preferably comprises a projector for projecting an image display on the windshield of the vehicle.
