Back-up Collision
Back-up collisions happen when a driver reverses the car into an object, person, or other car. Although most cars come equipped with rear view mirrors which are adequate for detecting vehicles behind a car, they are inadequate on many vehicles for detecting small children or objects close to the ground, which fall in the car's blind spot, particularly directly aft. That area has been called a "killing zone." Large trucks have much larger blind spots that can hide entire vehicles and large adults. Statistics According to research by the advocacy web site kidsandcars.org, back up collisions were the leading cause (34%) for U.S. non-traffic fatalities of children under 15 from 2006–2010. The U.S. Center for Disease Control reported that from 2001–2003, an estimated 7,475 children (CI = 4,453–10,497) (2,492 per year) under the age of 15 were treated for automobile back-over incidents. About 300 fatalities per year result from backup collisions. The U.S. National Highway Tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Car Safety
Automotive safety is the study and practice of design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles. Road traffic safety more broadly includes roadway design. One of the first formal academic studies into improving motor vehicle safety was by Cornell Aeronautical Laboratory of Buffalo, New York. The main conclusion of their extensive report is the crucial importance of seat belts and padded dashboards. However, the primary vector of traffic-related deaths and injuries is the disproportionate mass and velocity of an automobile compared to that of the predominant victim, the pedestrian. According to the World Health Organization (WHO), 80% of cars sold in the world are not compliant with main safety standards. Only 40 countries have adopted the full set of the seven most important regulations for car safety. In the United States, a pedestrian is injured by a motor vehicle every 8 minutes, and a ...

Side-view Mirror
A side-view mirror (or side mirror), also known as a wing mirror, is a mirror placed on the exterior of motor vehicles for the purposes of helping the driver see areas behind and to the sides of the vehicle, outside the driver's peripheral vision (in the " blind spot"). Almost all modern cars mount their side mirrors on the doors—normally at the A-pillar—rather than the wings (the portion of the body above the wheel well). The side mirror is equipped for manual or remote vertical and horizontal adjustment so as to provide adequate coverage to drivers of differing height and seated position. Remote adjustment may be mechanical by means of bowden cables, or may be electric by means of geared motors. The mirror glass may also be electrically heated and may include electrochromic dimming to reduce glare to the driver from the headlamps of following vehicles. Increasingly, the side mirror incorporates the vehicle's turn signal repeaters. There is evidence to suggest that mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precrash System
A collision avoidance system (CAS), also known as a pre-crash system, forward collision warning system, or collision mitigation system, is an advanced driver-assistance system designed to prevent or reduce the severity of a collision. In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles, so that it can provide a warning to the driver if the vehicles get too close, potentially helping to avoid a crash. Various technologies and sensors that are used include radar (all-weather) and sometimes laser (LIDAR) and cameras (employing image recognition) to detect an imminent crash. GPS sensors can detect fixed dangers such as approaching stop signs through a location database. Pedestrian detection can also be a feature of these types of systems. Collision avoidance systems range from widespread systems mandatory in some countries, such as autonomous emergency braking (AEB) in t ...

Parking Sensors
Parking sensors are proximity sensors for road vehicles designed to alert the driver of obstacles while parking. These systems use either electromagnetic or ultrasonic sensors. Ultrasonic systems These systems feature ultrasonic proximity detectors to measure the distances to nearby objects via sensors located in the front and/or rear bumper fascias or visually minimized within adjacent grills or recesses. The sensors emit acoustic pulses, with a control unit measuring the return interval of each reflected signal and calculating object distances. The system in turns warns the driver with acoustic tones, the frequency indicating object distance, with faster tones indicating closer proximity and a continuous tone indicating a minimal pre-defined distance. Systems may also include visual aids, such as LED or LCD readouts to indicate object distance. A vehicle may include a vehicle pictogram on the car's infotainment screen, with a representation of the nearby objects as coloured ...

Parking
Parking is the act of stopping and disengaging a vehicle and leaving it unoccupied. Parking on one or both sides of a road is often permitted, though sometimes with restrictions. Some buildings have parking facilities for use of the buildings' users. Countries and local governments have rules for design and use of parking spaces. Car parking is essential to car-based travel. Cars are typically stationary around 95 per cent of the time. The availability and price of car parking supports and subsidize car dependency. Car parking uses up a lot of urban land, especially in North America - as much as half in many North American city centers. Parking facilities Parking facilities can be divided into public parking and private parking. * Public parking is managed by local government authorities and available for all members of the public to drive to and park in. * Private parking is owned by a private entity. It may be available for use by the public or restricted to custom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omniview Technology
Omniview technology (also known as surround view or bird view) is a vehicle parking assistant technology that first was introduced in 2007 as the "Around View Monitor" option for the Nissan Elgrand and Infiniti EX. It is designed to assist drivers in monitoring their surroundings, for example, while parking a vehicle in a small space. Principle Early vehicle parking assistant products used ultrasonic parking sensors and/or a single rear-view camera to view and obtain distances to objects surrounding the vehicle, providing drivers with an audible alarm or rear-view video through a fisheye lens. There are some drawbacks to these early products: the alarm only provides a proximity warning but not the position of the object(s) relative to the vehicle, and the rear-view camera has a limited field of view. However, omniview technology overcomes these problems and has seen increasing availability. File:Rossi lhf safdao Y1.jpg, Input images; clockwise from upper left: views from the r ...

Objects In Mirror Are Closer Than They Appear
The phrase "objects in (the) mirror are closer than they appear" is a safety warning that is required to be engraved on passenger side mirrors of motor vehicles in many places such as the United States, Canada, Nepal, India, and South Korea. It is present because while these mirrors' convexity gives them a useful field of view, it also makes objects appear smaller. Since smaller-appearing objects seem farther away than they actually are, a driver might make a maneuver such as a lane change assuming an adjacent vehicle is a safe distance behind, when in fact it is quite a bit closer. The warning serves as a reminder to the driver of this potential problem. In popular culture Despite its origin as a utilitarian safety warning, the phrase has become a well known catch phrase A catchphrase (alternatively spelled catch phrase) is a phrase or expression recognized by its repeated utterance. Such phrases often originate in popular culture and in the arts, and typically spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Rangefinder
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used. Pulse The pulse may be coded to reduce the chance that the rangefinder can be jammed. It is possible to use Doppler effect techniques to judge whether the object is moving towards or away from the rangefinder, and if so, how fast. Precision The precision of the instrument is determined by the rise or fall time of the laser pulse and the speed of the receiver. One that uses very sharp laser pulses and has a very fast detector can rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lane Departure Warning System
In road-transport terminology, a lane departure warning system (LDWS) is a mechanism designed to warn the driver when the vehicle begins to move out of its lane (unless a turn signal is on in that direction) on freeways and arterial roads. These systems are designed to minimize accidents by addressing the main causes of collisions: driver error, distractions and drowsiness. In 2009 the U.S. National Highway Traffic Safety Administration (NHTSA) began studying whether to mandate lane departure warning systems and frontal collision warning systems on automobiles. There are four types of systems: *Lane departure warning (LDW): Systems which warn the driver if the vehicle is leaving its lane with visual, audible, and/or vibration warnings *Lane keeping assist (LKA/LKS): Systems which warn the driver and, with no response, automatically take steps to ensure the vehicle stays in its lane * Lane centering assist (LCA): Systems which assist in oversteering, keeping the car centered in th ...

Intelligent Car
Vehicular automation involves the use of mechatronics, artificial intelligence, and multi-agent systems to assist the operator of a vehicle (car, aircraft, watercraft, or otherwise).Hu, J.; Bhowmick, P.; Lanzon, A.,Group Coordinated Control of Networked Mobile Robots with Applications to Object Transportation IEEE Transactions on Vehicular Technology, 2021.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Transactions on Robotics, 2021. These features and the vehicles employing them may be labeled as ''intelligent'' or ''smart''. A vehicle using automation for difficult tasks, especially navigation, to ease but not entirely replace human input, may be referred to as ''semi-autonomous'', whereas a vehicle relying solely on automation is called robotic or autonomous. Both of these types are instantiated in today's various self-driving cars, unmanned surface vehicles, autonomous trains, advan ...

Intelligent Parking Assist System
Intelligent Parking Assist System (IPAS), also known as Advanced Parking Guidance System (APGS) for Toyota models in the United States, is the first production automatic parking system developed by Toyota Motor Corporation in 1999 initially for the Japanese market hybrid Prius models and Lexus models. The technology assists drivers in parking their vehicle. On vehicles equipped with the IPAS, via an in-dash screen and button controls, the car can steer itself into a parking space with little input from the user. The first version of the system was deployed on the Prius Hybrid sold in Japan in 2003. In 2006, an upgraded version debuted for the first time outside Japan on the Lexus LS luxury sedan, which featured the automatic parking technology among other brand new inventions from Toyota. In 2009, the system appeared on the third generation Prius sold in the U.S. In Asia and Europe, the parking technology is marketed as the Intelligent Park Assist System for both Lexus and Toyo ...
