A trip computer is an onboard computer A computer is a programmable machine that receives input, stores and manipulates data//information, and provides output in a useful format device fitted to cars An automobile, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the which can generally record distance travelled, average speed, average fuel consumption, and display real time In computer science, real-time computing , or reactive computing, is the study of hardware and software systems that are subject to a "real-time constraint"—i.e., operational deadlines from event to system response. By contrast, a non-real-time system is one for which there is no deadline, even if fast response or high performance is fuel consumption information. This computer can be found in various vehicles.

The first mechanical trip computers such as the "Halda Speedpilot", produced by a Swedish taximeter manufacturer, were made in the 1950s as a car accessory to enable the driver to maintain a given time schedule, particularly useful in rallying. One was installed as standard in the 1958 Saab GT750. In 1978, General Motors General Motors Company, also known as GM, is a United States-based automaker with headquarters in Detroit, Michigan. GM manufactures cars and trucks in 34 countries, recently employed 244,500 people around the world, and sells and services vehicles in some 140 countries. By sales, GM ranked as the largest US automaker and the world's second Cadillac Cadillac is a luxury vehicle marque owned by General Motors. Cadillac vehicles are sold in over 50 countries and territories, but mainly in North America division introduced the "Cadillac Trip Computer" available on the Cadillac Seville. Electronic ones were fitted in General Motors products, and are still usually reserved for more upscale cars, although some lower-end models are fitted with them often as an option. They can range from basic to complex. The most basic varieties of the trip computer incorporate average fuel mileage and perhaps an outside temperature display. Middle-of-the-road versions will often incorporate trip information into a bundle and include information on fuel, speed, distance, cardinal heading (compass), and elapsed time. The most advanced trip computers are reserved for high-end cars and often feature average calculations for two drivers, a stop watch, tire pressure information, an over-speed warning tone, as well as a multitude of other features.

Sometimes the trip computer display will be incorporated into the gauge cluster, into the dashboard or navigation system screen, or in an overhead console. Some vehicles will convey maintenance information to the driver to inform them of scheduled maintenance. The current Acura TL The Acura TL is a mid-size luxury car from Honda's Acura brand. It was introduced in 1996 to supplant the Acura Vigor and was rebadged for the Japanese-market from 1996 to 2000 as the Honda Inspire and from 1996 to 2004 as the Honda Saber. The TL is Acura's best-selling model, and it has ranked as the second best-selling luxury sedan in the United does this in stages, first alerting the driver with a 'Due Soon' message. Once the programmed mileage is reached, it alerts 'Due Now'. If the vehicle is driven past a certain point, the message will change to 'Past Due'. Mercedes-Benz vehicles constantly monitor the quality of the oil and alert the driver of the need of a change when the oil degrades to a certain extent.

Some trip computers can display the diagnostic codes mechanics use. This is specially useful when the mechanic wants to see what the codes are while driving the car. In 2004 Linear Logic developed the ScanGauge which at the time was the only easily installed (via OBDII) accessory that works as a trip computer, 4 simultaneous digital gauges, and a diagnostic trouble code reader. This device has available 12 different measurements which can be used as the 4 digital gauges. The units of measure can be independently selected between miles/km, gallons/liters, Celsius/Fahrenheit, and PSI/KPA.

In 2008, the OBDuino project announced[1] a low cost DIY Do it yourself is a term used to describe building, modifying, or repairing of something without the aid of experts or professionals. The phrase "do it yourself" came into common usage in the 1950s in reference to home improvement projects which people might choose to complete independently trip computer design using the OBDII interface and the Arduino hobbyist microcontroller platform, released under the GPL The GNU General Public License is the most widely used free software license, originally written by Richard Stallman for the GNU project open source license.

Automotive design Automotive design is the profession involved in the development of the appearance, and to some extent the ergonomics, of motor vehicles or more specifically road vehicles. This most commonly refers to automobiles but also refers to motorcycles, trucks, buses, coaches, and vans. The functional design and development of a modern motor vehicle is
Part of the Automobile An automobile, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the series
Body Coachwork is the body of a motor vehicle which is built around a chassis, rather than being of monocoque construction. Another word is carrossery (plural: carosseries)
Framework By far the most common, the C-rail has been used on nearly every type of vehicle at one time or another. It's made by taking a flat piece of steel and rolling both sides over to form a c-shaped beam running the length of the vehicle Automobile platform An automobile platform is a shared set of common design, engineering, and production efforts, as well as major components over a number of outwardly distinct models and even types of automobiles, often from different, but related marques • Body-on-frame Body-on-frame is an automobile construction technology. Mounting a separate body to a rigid frame that supports the drivetrain was the original method of building automobiles, and its use continues to this day. The original frames were made of wood , but steel ladder frames became common in the 1930s • Bumper An automobile's bumper is the front-most or rear-most part, ostensibly designed to allow the car to sustain an impact without damage to the vehicle's safety systems. They are not capable of reducing injury to vehicle occupants in high speed impacts, but are increasingly being designed to mitigate injury to pedestrians struck by cars • Cabrio coach A cabrio coach or semi-convertible is a type of car that has a retractable textile roof, and derives from Cabriolet. It is an inexpensive alternative to a full convertible, especially on cars with unibody designs since little or no redesign of the body is necessary • Chassis A chassis (pronounced /ˈʃæsi, ˈtʃæsi/) consists of an internal framework that supports a man-made object. It is analogous to an animal's skeleton. An example of a chassis is the under part of a motor vehicle, consisting of the frame (on which the body is mounted) with the wheels and machinery • Continental tire A Continental tire is an upright, external, mounted spare tire behind an automobile's trunk compartment. The term also describes a non-functional bulge that is stamped into the trunk lid or a cosmetic accessory to the rear of the car giving the impression of a spare tire mount • Crumple zone The crumple zone of an automobile is a structural feature designed to compress during an accident to absorb deformation energy from the impact. This energy is much higher than commonly recognised. The severity of a collision with a pole or tree at 60 km/h is similar to driving over a 10 metre sheer drop and crashing onto a hard surface. Typically, • Dagmar bumpers Dagmar bumpers, also known simply as Dagmars is a slang term for the artillery shell shaped styling elements found on the front bumper/grille assemblies on several makes of cars produced in the 1950s, an era recognized for its flamboyant designs and prominent use of chrome details[citation needed] • Decklid The decklid is the cover over the trunk/boot of motor vehicles that allows access to the main storage or luggage compartment. A hinge allows the decklid to be raised, while devices such as springs hold it up in the open position • Fender Fender is the US English term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well. Its primary purpose is to prevent sand, mud, rocks, and liquids from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface. Instead flexible mud flaps are • Fender skirts Fender skirts, known in Australia and the United Kingdom as spats, are pieces of bodywork on the fender that cover the upper portions of the rear tires of an automobile • Grille A grille or grill is an opening of several slits side by side in a wall or metal sheet or other barrier, usually to let air or water enter and/or leave but keep larger objects including people and animals in or out • Hood The hood or bonnet (UK) is the hinged cover over the engine of motor vehicles that allows access to the engine compartment for maintenance and repair. In British terminology, hood refers to a fabric cover over the passenger compartment of the car (known as the 'top' in the US). In many motor vehicles built in the 1930s and 1940s, the resemblance • Hood scoop A bonnet/hood scoop is an upraised component on the hood of an automobile that either allows a flow of air to directly enter the engine compartment, or appears to do so. It has one opening only and is closed on all other sides. Its main function is to allow a direct flow of air to the engine, hence the need for it to be upraised so as to • Monocoque Monocoque is a construction technique that supports structural load by using an object's exterior, as opposed to using an internal frame or truss that is then covered with a non-load-bearing skin or coachwork. The word monocoque comes from the Greek for single and French for shell (coque). The technique may also be called structural skin, stressed • Overhang Overhangs are the lengths of a car, at the front and rear, which extend beyond the wheelbase. They are normally described as front overhang and rear overhang. Practicality, style, and performance are affected by the size and weight of overhangs • Pillar An A-pillar is a name applied by car stylists and enthusiasts to the shaft of material that supports the windshield on either of the windshield frame sides. By denoting this structural member as the A-pillar, and each successive vertical support in the greenhouse after a successive letter in the alphabet (B-pillar, C-pillar etc.), this naming • Pontoon fenders Pontoon fenders are a type of fender for an automobile. Unfortunately, two entirely different types of fender are defined by this term. The earlier American meaning did not reach all nations. Later, a European use of the term, with cognates in several languages, was accepted by the British • Quarter panel On an automobile, a quarter panel is a body panel that covers the section between the rear door and the trunk. It is typically made of sheet metal, but is sometimes made of fiberglass and fibre-reinforced plastic. They are the parts of the exterior of the car that are left once the hood, trunk, roof, doors, bumpers, fenders, lights, and plastic • Shaker scoop A shaker scoop is an automobile term for an air intake for combustion air that is mounted directly on top of the engine's air cleaner and protrudes through a hole in the hood. Since it is fastened directly to the engine, it moves with the engine's movement and vibration on its mountings, thus the 'shaker' name • Spoiler A spoiler is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion. Spoilers on the front of a vehicle are often called air dams, because in addition to directing air flow they also reduce the amount of air flowing underneath the vehicle which reduces aerodynamic • Subframe A subframe is a structural component of a vehicle, such as an automobile or an aircraft, that uses a discrete, separate structure within a larger body-on-frame or unit body to carry certain components, such as the engine, drivetrain, or suspension. The subframe is bolted and/or welded to the vehicle. When bolted, it is sometimes equipped with • Tonneau Tonneau , in modern use, describes a hard or soft cover for a pickup truck bed. Hard tonneau covers open by a hinging or folding mechanism while soft covers open by rolling up
Compartments Trunk/Boot/Dickie The trunk or boot of an automobile or car is the vehicle's main storage, luggage, or cargo compartment. Trunk is used in North American English and Jamaican English; boot is used elsewhere in the English speaking world. Trunk is also primarily used in many non-English speaking regions, such as East Asia. In earlier usage, a boot was a built-in • Hood/Bonnet The hood or bonnet (UK) is the hinged cover over the engine of motor vehicles that allows access to the engine compartment for maintenance and repair. In British terminology, hood refers to a fabric cover over the passenger compartment of the car (known as the 'top' in the US). In many motor vehicles built in the 1930s and 1940s, the resemblance
Doors A vehicle door is a partition, typically hinged, but sometimes attached by other mechanisms such as tracks, in front of an opening which is used for entering and exiting a vehicle. A vehicle door can be opened to provide access to the opening, or closed to secure it. These doors are similar to doors used in buildings Butterfly doors Butterfly doors are a type of door often seen on high-performance automobiles. They are similar to scissor doors, but while scissor doors move up, butterfly doors also move outwards, which makes for easier entry/exit at the expense of saving space • Canopy door A vehicle canopy is a rarely used type of door for cars. It has no official name so it is also known as an articulated canopy, bubble canopy, cockpit canopy, canopy door, or simply a canopy. A canopy is a type of door which sits on top of a car and lifts up in some way, to provide access for passengers. It is similar to an aircraft canopy. There • Gull-wing door Gull-wing door is an automotive industry term describing car doors that are hinged at the roof rather than the side, as pioneered by the 1952 Mercedes-Benz 300SL race car (W194) and its road-legal version (W198) introduced in 1954 • Scissor doors Scissor doors are automobile doors that rotate vertically at a fixed hinge at the front of the door, rather than outwardly as with a conventional door • Sliding doors A Sliding door is a type of door that opens by sliding , whereby the door is either mounted on or suspended from a track. These aren't usually used in small vehicles, but generally they're most commonly used for minibuses and busses to provide a large entrance or exit for passengers without obstructing the pavement. They are often used on the side • Suicide door A suicide door is a car door that is hinged on the edge closer to the rear of the vehicle, known as the trailing edge. These doors are rarely used on vehicles in modern times because of their numerous problems
Glass Car glass includes windscreens, side and rear windows, and glass panel roofs on a vehicle. Side windows can be either fixed or be raised and lowered by depressing a button or switch or using a hand-turned crank handle. The power moonroof, a transparent, retractable sunroof, may be considered as an extension of the power window concept. Some Greenhouse The greenhouse of a car comprises the windscreen, rear and side windows, the more or less vertical pillars separating them (designated A-pillar, B-pillar and so on, starting from the car's front), and the car's roof • Power window Power windows or electric windows as well as electric or power window lifts (British English) are automobile windows which can be raised and lowered by depressing a button or switch, as opposed to using a hand-turned crank handle • Quarter glass Quarter glass (or quarter lite ) on automobiles and closed carriages may be a side window in the front door or located on each side of the car just forward of the rear window of the vehicle. Only some cars have them. In some cases the fixed quarter glass may set in the corner or "C-pillar" of the vehicle. Quarter glass is also sometimes • Sunroof An automotive sunroof is a fixed or operable opening in an automobile roof which allows light and/or fresh air to enter the passenger compartment.
