Reversing (vehicle Maneuver)
Reversing (also known as backing up) is the process of driving a vehicle in the reverse direction in order to maneuver. Rear view mirrors are somewhat standard equipment for this endeavor. Extremely large or luxury vehicles may have in addition technical aids such as backup cameras. Many industrial vehicles such as fork lifts automatically activate a repetitive warning beep whilst reversing. In the UK lorries may be fitted with warning devices which repeatedly announce "Attention: this vehicle is reversing", or the equivalent phrase in Welsh: "Sylw: mae'r Saeson wedi dwyn ein gwlad". Reversing a vehicle can serve the purpose of changing lanes in traffic when a driver wishes to change to an adjacent lane but the destination lane is relatively full of vehicles. This is performed by driving in the reverse direction until the vehicle can move into the adjacent lane (or adjacent lanes) at the back of the queue in the next lane. More commonly, reversing is used as an intermediate step ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parallel Parking
250px, Parallel-parked cars in Washington, D.C. 250px, A motorist gets assistance parallel-parking 250px, Parallel parking animation Parallel parking is a method of parking a vehicle parallel to the road, in line with other parked vehicles. Parallel parking usually requires initially driving slightly past the parking space, parallel to the parked vehicle in front of that space, keeping a safe distance, then followed by reversing into that space. Subsequent position adjustment may require the use of forward and reverse gears. Techniques Parallel parking is considered to be one of the most stressful and difficult skills for new drivers to learn. While parallel parking is a required part of most driving tests, several states in the US have dropped it as a requirement. Parallel parking enables the driver to park a vehicle in a smaller space than would be true of forward parking. Driving forward into a parking space on the side of a road is typically not possible unless two or mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rear-view Mirror
A rear-view mirror (or rearview mirror) is a flat mirror in automobiles and other vehicles, designed to allow the driver to see rearward through the vehicle's rear window (rear windshield). In cars, the rear-view mirror is usually affixed to the top of the windshield on a double-swivel mount allowing it to be adjusted to suit the height and viewing angle of any driver and to swing harmlessly out of the way if impacted by a vehicle occupant in a collision. The rear-view mirror is augmented by one or more side-view mirrors, which serve as the only rear-vision mirrors on trucks, motorcycles and bicycles. History Among the rear-view mirror's early uses is a mention by Dorothy Levitt in her 1909 book ''The Woman and the Car'' which noted that women should "carry a little hand-mirror in a convenient place when driving" so they may "hold the mirror aloft from time to time in order to see behind while driving in traffic". However, earlier use is described in 1906, in a trad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 colour ...

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.

Blind Spot (vehicle)
A blind spot in a vehicle or vehicle blind spot is an area around the vehicle that cannot be directly seen by the driver while at the controls, under existing circumstances. In transport, driver visibility is the maximum distance at which the driver of a vehicle can see and identify prominent objects around the vehicle. Visibility is primarily determined by weather conditions (see visibility) and by a vehicle's design. The parts of a vehicle that influence visibility include the windshield, the dashboard and the pillars. Good driver visibility is essential to safe road traffic. Conditions for blind spots Blind spots exist in a wide range of vehicles: aircraft, cars, buses, trucks, agricultural equipments, heavy equipments, boats, ships, trams, and trains. Blind spots may occur in the front of the driver when the A-pillar (also called the windshield pillar), side-view mirror, or interior rear-view mirror block a driver's view of the road. Behind the driver, cargo, headrest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backup Camera
A backup camera (also called a reversing camera or rear-view camera) is a special type of video camera that is produced specifically for the purpose of being attached to the rear of a vehicle to aid in backing up and to alleviate the rear blind spot. It is specifically designed to avoid a backup collision. The area directly behind vehicles has been described as a "killing zone" due to associated accidents. Backup cameras are usually connected to the vehicle head unit display. A common variant is a Surround View system, which assembles a synthetic but positionally accurate top-down view of the vehicle and its adjacencies. Backup cameras have been regulated by specific law in Canada and the United States since 2018. Function The design of a backup camera is distinct from other cameras in that the image is horizontally flipped so that the output is a mirror image. This is necessary because the camera and the driver face opposite directions, and without it, the camera's right would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
J-turn
A J-turn is a driving maneuver in which a reversing vehicle is spun 180 degrees and continues, facing forward, without changing direction of travel. The J-turn is also called a " moonshiner's turn" (from the evasive driving tactics used by bootleggers), a "reverse 180", a reverse flick, a "Rockford Turn", a "Rockford Spin", or simply a "Rockford" popularized by the 1970s TV show ''The Rockford Files''. A J-turn differs from a bootleg turn in that the vehicle begins in reverse gear. It is often performed by stunt drivers in film and television shows. It can be performed both on dry and snowy surfaces; the latter is preferable while learning the skill. Technique The turn is achieved by transferring the momentum of the car by reversing quickly in a straight line then turning the wheel sharply while using a brake to lock the front wheels. The driver changes into a forward gear as the nose comes about. World record The narrowest J-turn was performed in a Renault Twingo, between ...

Driving
Driving is the controlled operation and movement of a vehicle, including cars, motorcycles, trucks, buses, and bicycles. Permission to drive on public highways is granted based on a set of conditions being met and drivers are required to follow the established road and traffic laws in the location they are driving. The word driving, has etymology dating back to the 15th century and has developed as what driving has encompassed has changed from working animals in the 15th to automobiles in the 1800s. Driving skills have also developed since the 15th century with physical, mental and safety skills being required to drive. This evolution of the skills required to drive have been accompanied by the introduction of driving laws which relate to not only the driver but the driveability of a car. Etymology The origin of the term ''driver'', as recorded from the 15th century, refers to the occupation of driving working animals, especially pack horses or draft horses. The verb ...

Three-point Turn
The three-point turn (sometimes called a Y-turn, K-turn, or broken U-turn) is the standard method of turning a vehicle around to face the opposite direction in a limited space, using forward and reverse gears. This is typically done when the road is too narrow for a U-turn. This manoeuvre is a common requirement in driving tests. Process The basic manoeuvre consists of driving across the road turning towards the offside curb, reversing across the road to the original nearside curb while turning, and driving forward towards the original offside curb, now the nearside. In a narrow road or with a longer vehicle, more than three legs may be required to achieve a full 180 degree rotation. Naming ''"Three point turn"'' is the formal name in Australia, Canada, New Zealand, and in many regions of the United States. Less common terms are: ''"Y-turn"'', ''"K-turn"'', and ''Broken U-turn'' but in the UK, the official name is ''"Turning in the road (using forward and reverse gears)"'' ...
