An Improved Radar Anticollision Device

Collision Avoidance Systems-John B. Flannery, John C. Sims, Snelling R. Brainard, Leon Ruderman
Published 1979-02-01 by SAE International in United States
The authors describe an automotive anticollision device which uses pulsed radar and is controlled by a microprocessor. The radar and its control significantly reduce false target response, loss of braking due to multi-path signal cancellation and blinding from other radar equipped vehicles. Increased range with reduced false target response allows warning of an impending collision and effective automatic braking.

Automatic Braking by Radar

AutoStop Corp.-John B. Flannery
Published 1974-02-01 by SAE International in United States
Braking system, developed by AutoStop Corp., uses doppler-generated signals to reduce stopping distance of vehicle in danger of collision. Safety device acts on conventional controls of vehicle, provides backup where driver's reaction time is not adequate, and rapid deceleration is required to avoid collision. Actuation of controls to achieve deceleration is accomplished by two vacuum bellows, one mechanically linked to the brake pedal, another linked to throttle and accelerator. Braking action is initiated by driver. System discriminates between objects which present danger of collision, and false targets such as traffic in adjacent lanes and signposts.
