retrovision-system RV3b

Propuesta para reemplazar Espejos Retrovisores por C谩maras y Displays LCD / RV.3

Weiss Design 路 2010

Intro Cuándo aparco mi automóvil en la vía pública (por ejemplo al lado de la acera o en un aparcamiento), los espejos retrovisores en el exterior de las puertas corren el riesgo de ser alcanzados por otros vehículos que pasan demasiado cerca. Después de haber sufrido repetidas roturas de espejos (multa incluida), me propuse buscar una manera de sustituir los espejos aprovechando los avances en la tecnología digital

Propuesta: La propuesta consiste en reemplazar los espejos grandes por videocámaras pequeñas y discretas, conectadas a monitores colocados en el tablero dentro del campo de visión del conductor

Objetivo: Evitar los peligros y molestias ocasionados por la rotura de los espejos retrovisores.

Funcionamiento: Las cámaras se colocan en el lado izquierdo + derecho exterior y en la zona central trasera (interior o exterior) del vehículo, pudiéndose regular su orientación y ángulo de vista desde el conductor. Tres monitores (displays LCD) agrupados encima de los instrumentos del tablero transmiten las imágenes al conductor, pudiéndose ajustar su luminosidad, contraste y dirección.

Beneficios: Las cámaras, por su tamaño pequeño y discreto, son poco expuestas a roturas e interferencias climáticas. Las tres imágenes de retro-visión sobre el volante hace al conductor más consciente del entorno y le permite, casi sin desviar la mirada, averiguar si puede hacer un cambio de carril

Comentarios: Es posible que los actuales displays sean todavía demasiado caros y su calidad de imagen no sea todavía suficiente para garantizar la seguridad del sistema propuesto. Pero la evidente evolución de esta tecnología permite suponer que pronto alcanzarán las cualidades necesarias y bajarán sus costos. Prueba de ello es el fuerte crecimiento de negocio en este sector que, según los pronósticos de los expertos, se duplicará en los próximos 6 años (ver artículo siguiente)

Automotive displays see continuous growth Written by Christoph Hammerschmidt http://www.esemagazine.com

Despite the ongoing recession in the automotive market, the market for automotive displays remains hot, featuring high growth rates over the next years, says DisplaySearch.

In its current Automotive Display Report, the Austin, Texas, based market researcher predicts that in 2009, about 175 million displays will be built, representing a value of $1,77 billion. In 2015, the market researchers believe the industry will achieve revenues of $2.4 billion on a production of 231 million units.

The strongest growth will be seen in the segment of automotive monitors —activematrix LCDs and typically featuring sizes larger than 15 centimeters (6 inches).

These displays will be used predominantly for navigation applications. For 2009, about 41 percent of these displays will have touch screens.

.

For this part of the market, DisplaySearch forecasts the market volume to grow to 34.4 million units in from 16.6 million units in 2009. The value of these shipments will increase by 51 percent to $1.56 billion in 2015. Driving forces in this market segment are demand for in-console displays for navigation and entertainment purposes. While DisplaySearch sees rising demand for fixed incar monitors, the experts believe the demand for portable navigation devices will shrink at a CAGR of 3.9 percent during the time frame in question.

Another major market segment are displays used as indicator, dials and gauges.

While this segment is predicted to grow from about 160 million units in 2009 to about 200 million units in 2015, the value of these displays will be almost constant at $800 million over the next six years.

Among the vendors, TMDisplay is the 500-pound gorilla with a market share of 38 percent, followed by Sharp with 31.4 percent. Other large vendors are AUO (9.7 percent), Epson (7.3 percent) and Optrex with 4.9 percent market share.

Optrex and Epson have dramatically increased their shipments in 2008, notes DisplaySearch.

The market is divided among relatively few buyers, with Panasonic, Continental, Pioneer, Fujitsu-TEN and Alpine accounting for more than half the units in recent quarters, the market researchers noted.

Why Do All Cars Look the Same?

The experts tell you about the future of automotive design

By Rex Roy · Editor-at-Large, AOL Autos http://autos.aol.com/article/car-design/ Posted: Feb 24, 2010

Have you ever exited a supermarket and wondered why you couldn't find your car? Chances are you suffered from something all of us have at some point: cars tend to look a lot alike these days. But, why? Furthermore, what do today's best automotive designers think cars will look like twenty years from now? Will cars fly or be a predictable evolution of what's on the road today?

Discussing the future of automobiles is a favorite pastime among those in the automotive business. Designers and engineers from every generation have put their dreams on paper (or LCDs). Some have even been spectacularly brought to life. The Firebird concepts are a trio of future-think cars produced by General Motors for their Motorama shows of the 1950s. Jet airplanes influenced these show-only creations that included such innovations as turbine engines, drive-by-wire controls, and titanium bodies.

But GM's designers from the Eisenhower era didn't accurately predict the future, although many cars today do feature drive-by-wire controls and lightweight alloys. Even though cars have never looked like the finned Firebirds, this design folly doesn't damp today's crop of automotive designers from offering opinions on what the cars of 2028 may look like.

At a recent Automotive Press Association gathering in Detroit, senior designers participated in a panel discussion about automotive design trends. The distinguished panel consisted of Pat Schiavone from Ford, Dave Marek of Honda, Nissan's Robert Bauer, Ty Stump from Chrysler, and John Cafaro from GM. These styling masters identified key trends that will drive automotive design for the next decade and beyond.

It's All About Aero Did you ever wonder why the fuel-sipping Toyota Prius and the Chevrolet Volt electric car have nearly the same profile in silhouette? Aerodynamics. Any aero engineer knows that a car designed for maximum mileage must enter the air smoothly and have a relatively sharp cutoff at the rear (to cleanly detach the air stream from the body). The general shape of Prius and Volt use a similar approach to meet their aerodynamic (and fuel economy) targets.

What you don't see when you look at the Prius or Volt are the painstakingly details that enhance the general shape of the vehicles to make them more efficient at piercing the air. Whereas older cars used to have window frames around the side glass that could catch the wind, the Prius and Volt have nearly smooth side surfaces -- even the door handles are aerodynamically designed. The APA design panel agreed that "smoothness" is the trend future.

Cars like GM's 1996 EV1 and the 2000 Honda Insight have already shown the world what radical (but practical) aero designs look like. Their diminutive size helped mileage, and foreshadowed our current enchantment with smaller cars (like the smart fortwo). Among their many aerodynamic features were skirted rear wheels. These cars foreshadowed the smoothness trend.

In the future, designers will embrace new technologies to make cars smoother still. For example, large wind-catching exterior rearview mirrors will be replaced with miniature rearfacing cameras that have no aerodynamic drag. (These cameras will display what's behind you on interior monitors.)

Evolution vs. Revolution Designers talked about the public's resistance to designs that are too wild or aggressive. Honda's Dave Marak opines that more vehicles will take on the cab-forward look of his company's hydrogen-powered FCX. "People have seen this general shape before, and this is something they're willing to park in their driveway," he thinks. …………………… a.s.o.….

Ideas Into Execution:

Giving Away An Idea To Make It Happen We spend a lot of time talking about innovation and ideas. Part of that discussion often turns to patents, and questions of whether it is better to "protect" or "hoard" your ideas, or to focus on sharing them. Patents live in this nebulous world between the two, where you partially (sort of) "give away" the idea, in exchange for the right to protect it. This seems counterintuitive when you think about it. Plenty of research has shown that people invent and innovate more often because they want what they're inventing themselves -- not because they want some sort of monopoly right over it. Other research has shown how innovation (rather than invention) is really an ongoing process, that often involves building on various ideas. For years, we've discussed how the "idea" is quite often overvalued, while the execution is undervalued. Lots of people have ideas. How you execute on them is where the real innovation occurs.
