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 ...

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 ...

Moving Object Detection
Moving object detection is a technique used in computer vision and image processing. Multiple consecutive frames from a video are compared by various methods to determine if any moving object is detected. Moving objects detection has been used for wide range of applications like video surveillance, activity recognition, road condition monitoring, airport safety, monitoring of protection along marine border, etc. Definition Moving object detection is to recognize the physical movement of an object in a given place or region.

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 ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ...

Experimental Safety Vehicle
Experimental Safety Vehicle (ESV) is the designation for experimental concept cars which are used to test car safety ideas. In 1973, the United States Department of Transportation, U.S. DOT announced its ESV project, the aim of which was to obtain safer vehicles by 1981. A car produced by this effort was known as the Minicar RSV. In 1991, the ESV abbreviation was backronymed to ''Enhanced Safety of Vehicles''.

Convex Mirror
A curved mirror is a mirror with a curved reflecting surface. The surface may be either ''convex'' (bulging outward) or ''concave'' (recessed inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems, like spherical Lens (optics), lenses, suffer from spherical aberration. Distorting mirrors are used for entertainment. They have convex and concave regions that produce deliberately distorted images. They also provide highly magnified or highly diminished (smaller) images when the object is placed at certain distances. Convex mirrors A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to f ...

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 ...

Blind Spot Monitor
The blind spot monitor or blind-spot monitoring is a vehicle-based sensor device that detects other vehicles located to the driver’s side and rear. Warnings can be visual, audible, vibrating, or tactile. Blind spot monitors may do more than monitor the sides and rear of the vehicle. They may also include "Rear Cross-Traffic Alert", "which alerts drivers backing out of a parking space when traffic is approaching from the sides." History If side view mirrors on a car are adjusted in a particular way, there is no blind spot on the sides. This method was first revealed by George Platzer in a 1995 paper presented to the Society of Automotive Engineers, but the method is frequently overlooked in driver's education classes and takes some getting used to. Calculated elimination of blind spots by trained drivers is inexpensive and obviates the need for expensive technological solutions to that problem, provided drivers take the time to set up and use their mirrors properly. Pla ...

Backup 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 ...

Automatic Parking
Automatic parking is an autonomous car-maneuvering system that moves a vehicle from a traffic lane into a parking spot to perform parallel, perpendicular, or angle parking. The automatic parking system aims to enhance the comfort and safety of driving in constrained environments where much attention and experience is required to steer the car. The parking maneuver is achieved by means of coordinated control of the steering angle and speed which takes into account the actual situation in the environment to ensure collision-free motion within the available space. The car is an example of a nonholonomic system where the number of control commands available is less than the number of coordinates that represent its position and orientation. One of the first assistance systems for car parking was manual. It used four jacks with wheels to raise the car and then move it sideways into the available parking space. This mechanical system was proposed in 1934, but was never offered on any ...
