A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
Volvo City Safety multiple cameras. 2006: Volvo's "Collision Warning with Auto Brake" was introduced in 2007 S80. This system is powered by a radar/camera sensor fusion and provides a warning through a head up display that visually resembles brake lamps. If the driver does not react, the system pre-charges the brakes and increases the brake ...
The electromagnetic parking sensor (EPS) was re-invented and patented in 1992 by Mauro Del Signore. [2] Electromagnetic sensors rely on the vehicle moving slowly and smoothly towards the object to be avoided. Once an obstacle is detected, the sensor continues to signal the presence of the obstacle even if the vehicle momentarily stops.
Specifically, the driver monitoring system includes a CCD camera placed on the steering column which tracks the face, [2] via infrared LED detectors. [3] If the driver is not paying attention to the road ahead and a dangerous situation is detected, the system will warn the driver by flashing lights, warning sounds.
This camera offers driver's aid when backing up by providing a viewpoint that is typically a blind spot in traditional cars. [14] When the driver puts the car in reverse, the camera automatically turns on. [14] Glare-free high beam use Light Emitting Diodes, more commonly known as LEDs, to cut two or more cars from the light distribution. [51]
While only a concept car, the Ford GT90 was the first vehicle to be fitted with a modern blind spot monitoring system. [7] Currently, Ford uses the acronym BLIS for its blind spot detection. The system is active both in "drive" and "neutral" transmission gears, and is turned off when in reverse or park gears. [8]
A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors . PIR sensors are commonly used in security alarms and automatic lighting applications.
A lane detection system used behind the lane departure warning system uses the principle of Hough transform and Canny edge detector to detect lane lines from realtime camera images fed from the front-end camera of the automobile. A basic flowchart of how a lane detection algorithm works to help lane departure warning is shown in the figures.
