Car Navigation System

An automotive navigation system is a satellite navigation system designed for use in automobiles. It typically uses a GPS navigation device to acquire position data to locate the user on a road in the unit's map database. Using the road database, the unit can give directions to other locations along roads also in its database. Dead reckoning using distance data from sensors attached to the drivetrain, a gyroscope and an accelerometer can be used for greater reliability, as GPS signal loss and/or multipath can occur due to urban canyons or tunnels.

Some sorts can be taken out of the car and used hand-held while walking.

HISTORY
                     Automotive navigation systems were the subject of extensive experimentation, including some efforts to reach mass markets, prior to the availability of commercial GPS.

Most major technologies required for modern automobile navigation were already established when the microprocessor emerged in the 1970s to support their integration and enhancement by computer software. These technologies subsequently underwent extensive refinement, and a variety of system architectures had been explored by the time practical systems reached the market in the late 1980s. Among the other enhancements of the 1980s was the development of color displays for digital maps and of CD-ROMs for digital map storage. However, there is some question about who made the first commercially available automotive navigation system. There seems to be little room for doubt[says who?] that Etak was first to make available a digital system that used map-matching to improve on dead reckoning instrumentation. Etak's systems, which accessed digital map information stored on standard cassette tapes, arguably made car navigation systems practical for the first time. However, Japanese efforts on both digital and analog systems predate Etak's founding. Steven Lobbezoo developed the first commercially available satellite navigation system for cars. It was produced in Berlin from start 1984 to January 1986. Publicly presented first at the Hannover fair in 1985 in Germany, the system was shown in operation on the evening news (item in the Hannover fair) from the first German television channel in that year. It used a modified IBM PC, a large disc for map data and a flat screen, built into the glove compartment. It was called Homer (after the device from a James Bond movie).
Alpine claims to have created the first automotive navigation system in 1981. However, according to the company's own historical timeline, the company claims to have co-developed an analog automotive navigation product called the Electro Gyrocator, working with Honda. This engineering effort was abandoned in 1985. Although there are reports of the Electro Gyrocator being offered as a dealer option on the Honda Accord in 1981, it's not clear whether an actual product was released, whether any customers took delivery of an Electro Gyrocator-equipped Accord, or even whether the unit appeared in any dealer showrooms; Honda's own official history appears to pronounce the Electro Gyrocator as not practical. See below for Honda's history of the project.
Honda claims to have created the first navigation system starting in 1983, and culminating with general availability in the 1990 Acura Legend. The original analog Electro Gyrocator system used an accelerometer to navigate using inertial navigation, as the GPS system was not yet generally available. However, it appears from Honda's concessions in their own account of the Electro Gyrocator project that Etak actually trumped Honda's analog effort with a truly practical digital system, albeit one whose effective range of operation was limited by the availability of appropriately digitized street map data.
 progress in digital technology would not stop simply because Honda had turned its attention to analog. In 1985, for example, the U.S. company ETAK introduced its own digital map navigation system. Although the system's effective range-the area of geographical coverage-was limited, the announcement was a dour one for Nakamura and his staff. Therefore, ultimately the development of a practical analog system was shelved. The staff experienced indescribable feelings of disappointment. The development of [Honda's] digital map navigation system resumed in 1987, following a three-year hiatus.
Both Mitsubishi Electric and Pioneer claim to be the first with a GPS-based auto navigation system, in 1990. Also in 1990, a draft patent application was filed within Digital Equipment Co. Ltd. for a multi-function device called PageLink that had real-time maps for use in a car listed as one of its functions.
Magellan, a GPS navigation system manufacturer, claims to have created the first GPS-based vehicle navigation system in the U.S. in 1995.
In 1995, Oldsmobile introduced the first GPS navigation system available in a production car, called GuideStar. There also was an Oldsmobile navigation system available as an option as early as 1994 called the Oldsmobile Navigation/Information System. It was an option on the Oldsmobile Eighty Eight.
However it was not until 2000 that the United States made a more accurate GPS signal available for civilian use.

Visualization

Navigation systems may (or may not) use a combination of any of the following:
top view for the map
top view for the map with the map rotating with the automobile (so that "up" on the map always corresponds to "forward" in the vehicle)
bird's-eye view for the map or the next curve
linear gauge for distance, which is redundant if a rotating map is used
numbers for distance
schematic pictograms
voice prompts

Contents

The road database is a vector map of some area of interest. Street names or numbers and house numbers are encoded as geographic coordinates so that the user can find some desired destination by street address (see map database management).

Points of interest (waypoints) will also be stored with their geographic coordinates. Point of interest specialties include speed cameras, fuel stations, public parking, and "parked here" (or "you parked here").

Contents can be produced by the user base as their cars drive along existing streets (Wi-Fi) and communicating via the internet, yielding a free and up-to-date map.

• The New Model consists of a more sporty, elegant and dynamic design.
• For the exterior, a dynamic and advanced image is created by a “wide & low packaging” and a low center-of-gravity. Therefore a stable image is reinforced, especially in the front view.

lexus lfa

The Lexus LFA is a two-seat exotic sports coupe produced by Lexus as a concept car, "halo" vehicle, racing prototype, and production model. It is the second model in the F marque line of performance vehicles from Lexus, following the IS F. Three concept versions have been shown, each debuting at the North American International Auto Show with the LF-A designation as part of the LF Series concept line. The first LF-A concept premiered in 2005, followed in 2007 by a second LF-A with a more completely furnished interior and exterior. The third version of the LF-A, a roadster model, premiered in 2008. The production model, trademarked LFA, was shown at the Tokyo Motor Show in October 2009.
The production Lexus LFA features a new V10 engine and a carbon fiber-reinforced polymer (CFRP) body. CFRP materials account for 65 percent of the LFA's body composition by mass. The LFA is scheduled to go into production in late 2010, with a projected run of 500 vehicles at the base price of US$375,000. A circuit-tuned variant is scheduled for 2012.

The Lexus LFA is powered by a 72-degree bank angle 4.8-liter V10 engine equipped with dual VVT-i carrying the 1LR-GUE designation with a maximum output of 560 PS (412 kW) delivered at 8,700 rpm. Its maximum torque output of 354 lb·ft (480 N·m) arrives at 6,800 rpm, 90 percent of which is available from 3,700 rpm. The engine redlines at 9,000 rpm, but with a fuel cutoff set at 9,500 rpm, and is constructed using forged aluminum pistons, forged titanium connecting rods, and solid titanium valves. The V angle of the LFA's V-10 engine is set to 72-degrees (as opposed to, say, the 90-degree V angle present in a Dodge Viper's V-10) to fully balance the firing force from the pistons. This 72-degree angle allows for even firing from the pistons without the use of a split-journal crankshaft, thus improving engine efficiency as well as lowering overall weight. Dry sump lubrication prevents engine oil starvation through high speed corners and lowers the engine's center of mass. Air is fed directly from beneath the hood through a visible slit passing into a dual stage variable intake manifold and then into ten individual throttle bodies before finally exiting from a dual stage titanium muffler.

The LFA's engineers selected a V10 engine over an equivalent displacement V8 engine for its higher revs, and over a V12 for its lower reciprocating mass, allowing for more rapid engine response. Lexus claims their engine can rev from idle to its redline in 0.6 seconds and an analog tachometer needle could not accurately track the LFA's changes in engine speeds. This necessitated the use of a digital tachometer which can instantly display engine speed.The engine reportedly weighs less than the manufacturer's own 3.5-liter 2GR-FE V6 engine. Engineers attempted to make the engine sound like that of a Formula One car with high revs, while at the same time maintaining reliability and vibration control. Along with other manufacturers such as Ferrari, Toyota had produced their own F1 engines and chassis designs. The exhaust note has been described by Toyota engineers as the "roar of an angel", and a US television spot later used the engine sound to shatter a champagne glass via resonance frequency.

The powerplant gives the LFA a power-to-weight ratio of 5.9 lb/hp and enables it to reach a top speed of around 202 mph (325 km/h). Like the IS F Yamaha co-developed the engine cylinder heads. The engine exceeds Euro V emissions. The engine is installed with a front mid-engine placement. According to Chief Engineer Haruhiko Tanahashi a front engine layout was selected instead of a mid engine layout as it is inherently more forgiving dynamically, affording less experienced drivers a wider safety net.

acura tsx

The Acura TSX is an entry-level luxury car manufactured by Acura. Introduced in April 2003, it was sold only in the United States and Canada, but from the 2009 model year on it will also be available in Mexico. It is sold in North America under the Acura luxury marque, where it filled the gap as Acura's 4-door, entry-level sedan when the Integra sedan was discontinued in 2001 (1996 in Canada since the EL was the Integra sedan's replacement there). The TSX would also eventually replace the Acura RSX in the US (which in turn succeeded the Acura Integra coupe). As of 2008, the TSX is the smallest vehicle in the Acura model line, other than the Civic-based CSX (and the preceding 1.6/1.7EL) sold only in Canada. All TSXs are built in Sayama, Saitama, Japan.
The TSX is badge engineered from the CL-series Accord (also known as the European Accord or JDM Accord) sold in Europe, Japan, Australia and New Zealand. The TSX initially had a restyled interior and different suspension tuning than the European Accord when it was introduced; however since 2008 the interior is now standardized for all three markets. In Australia & New Zealand, the CL-series is sold as the Accord Euro in the smaller mid-size bracket, where the American-market Accord is sold in the large car category. In North America, the TSX is sold alongside the mid-size luxury Acura TL, which is based on the American-market Accord.

Engine

The new TSX uses a base engine similar to that of the 2008 TSX. The engine is a 2.4-litre in-line 4 cylinder engine reaching 201 hp (150 kW) and 172 lb·ft (233 N·m) torque. While the rated power of the new TSX engine is 4 hp (3.0 kW) lower than that of the 2008 model, Acura says the new engine distributes power across a much wider rpm range, which along with the increased torque, provides an increased feeling of power for the driver. The transmission choices remain 5-speed automatic and 6-speed manual, though the automatic version now comes with steering-wheel paddle shifters for optional manual shifting.
The TSX was slated to receive a high performance 2.2-litre i-DTEC clean turbodiesel engine in the 2010 model year; however, it was later announced that Honda had abandoned its plans to bring diesel engines to the U.S. and Japan in favor of hybrid gasoline-electric powertrains. Instead, a 280 hp 3.5-litre V6 will be available in the 2010 Acura TSX. The TSX V6 will only be available with the 5-speed automatic transmission.
The Acura TSX has a narrow price elasticity, as the base model 4-cylinder TSX is considered a good deal for a luxury car, however higher trims (particularly the V6 powered models) are considered too expensive as they compete directly with sport luxury cars such as the Audi A4 and Infiniti G
