Heads-up display system for a road vehicle
First Claim
1. A heads-up display system for a road vehicle, comprising:
- a sensor for detecting motion-related information on the vehicle while the vehicle is being driven along a road;
computing means for predicting the future course of motion of the vehicle according to the motion-related information detected by said sensor and parameters associated with the vehicle;
display means for displaying the information within the normal road view of a driver of the vehicle, the information including a limit turning trajectory which gives rise to a certain limit lateral acceleration when the vehicle moved along the limit turning trajectory at a current speed of the vehicle; and
conversion means for converting the predicted motion of the vehicle into an image display on said display means so as to permit the driver to see said image display in a certain relationship with his view of the actual road ahead of said vehicle.

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.
