A LASER-CONTROLLED AUTOMATED VEHICLE OPERATION SYSTEM

A necessary condition for automated vehicle operation is the ability to look forward to (1) the direction and (2) the speed at which the vehicle should be going. In the proposed look-ahead angle-controlled vehicle operating system (LAVOS), the necessary signals are derived from a system of three sensing lasers, which are installed at the front of each vehicle. On the highway side the only installations are infrared light reflectors on the lane dividing lines. The active sensing, speed, and steering control work is completely done at the vehicle terminal. A simple steering control law is derived. Simulation studies show that the control law is very stable and keeps the vehicle at lane center. The LAVOS control principal has many advantages. Chief among these are the following: 1) LAVOS is versatile, working equally well on country roads, arterials, and super highways; 2) LAVOS is easy to install, both as a steering control on all makes and types of vehicles and as removable reflectors on highway infrastructure; and 3) LAVOS provides excellent riding quality in terms of stability, safety, and comfort.
