Backup Warning Systems Drivers often have a limited view of objects behind the vehicle when a vehicle is being reversed. This can result in advertent collisions resulting in personal injury to unseen individuals, such as small children playing on driveways, or in damage to the vehicle from striking short posts or walls in parking lots. A backup warning system provides an alert to the vehicle driver if the presence of an unseen object behind their vehicle is detected.   How do they work? Backup warning systems may use radar or ultrasonic transmitters and receivers facing to the rear of the vehicle in order to detect any objects in the path as the vehicle reverses. The detector is wired into the vehicle's reversing light circuit so that it is only operation when the vehicle is being operated in reverse gear. The system detects objects behind the vehicle and gives either audible warnings or illuminates a series of lights to indicate the vehicle's proximity to the object. Some systems use a rearward-looking camera to identify objects behind a vehicle that is reversing. The resulting image can be monitored directly by the driver on an in-vehicle display screen or in a specially modified rear view mirror. Alternatively, computer-based image processing can be used to automatically detect fixed objects and/or pedestrians and issue an alert. As the green car reverses, the beam from its backup warning system identifies the presence and proximity of the red car   Useful links Guardian Alert (Sense Technologies) Guardian Alert: How it works Radar Obstacle Sensing System (Nassau Technologies) Stellar Backup Warning Systems (The Hoffman Group) Rear Facing Camera Applications (MobileEye) Rear View Camera Systems (Visor-View) RearSight Back-Up Camera Systems (Rostra Precision Controls)   On-line Video Clips ReverseGUARD (American Road Products)
