Continental Creates Intelligent Car Windows
- The latest film technology enables targeted shading of car windows
- "Intelligent Glass Control" offers new opportunities for increased comfort, safety and lower emissions
AUBURN HILLS, Mich., Dec. 10, 2015 /PRNewswire/ -- The international automotive supplier Continental has developed a new generation of film technology for shading of car windows. The "Intelligent Glass Control" uses special films that are inserted into the glass and change transparency through electric control signals.

"The selective, incremental darkening of the side and rear windows, as well as parts of the windshield, not only offers considerably increased comfort for passengers, but also makes driving safer," said Andreas Wolf, head of Continental's Body & Security business unit. "When the sun is low over the horizon, the driver's hand instinctively goes from the steering wheel to the sun visor, which results in both impaired visibility and a brief decrease in control of the vehicle. In the future, such situations can be detected in advance and the windows could darken automatically before the event even occurs," Wolf said.
Darkening saves energy
By using these films, the solar radiation can be reduced more effectively than with other technologies. As a result, the heat is kept out of the vehicle, which can significantly reduce the interior temperature. This relieves the air conditioning unit, which can be smaller, more energy efficient and lighter. Furthermore, the weight of the sun visors and mechanical blinds are removed which all lead to positive effects on the environment.
"Our calculations have shown that the CO(2) emissions are reduced by a good four grams per kilometer thanks to these measures, ultimately increasing the range of electric vehicles by around 5.5 percent," Wolf said.
In addition to the reduced heat in the interior, the darkening also effectively enhances privacy. "If the vehicle is parked, the windows darken automatically, so the inside of the vehicle cannot be seen from the outside."
Intelligent Glass Control also gives designers new options. According to Wolf, the glass surfaces could be extended further, without having to cover certain areas mechanically. The available film still has a slightly blue shimmer, but Continental is expecting a broader range of colors in the future, opening up additional design possibilities. Other effects, from coupling light effects through energy recovery to touch screen functionalities, may also be possible.
Particles align under current
Films with embedded particles that can be aligned when a voltage is applied and can be used for targeted darkening of the window have been available for a long time. This technology has only been feasible in the roof area for a small number of high-end cars. Continental is demonstrating the intelligent activation of the "Suspended Particle Device" film technology also for side and rear windows and the windshield, which is a first for application in a test vehicle. Due to legal requirements this is only implemented in the permitted area of the sun visors.
"This production-ready film technology is based on embedded particles that arrange themselves randomly when unpowered and darken the window from the outside, while retaining transparency from the inside to the outside. Once a voltage is applied, the particles systematically align themselves in parallel, so that the window becomes permeable to light in both directions. The connection to the vehicle system enables the windows to lighten automatically when you approach the vehicle with a key or smartphone," Wolf said.
Even though the film is still rather cost-intensive for mid-range vehicles with large glazed areas, it is anticipated that the prices will quickly drop due to further promising developments with initial applications in the mobile area. Other alternatives to film technology are based on liquid crystal polymers or electrochromism. The latter uses the ability of molecules and crystals to change their optical properties under the influence of an electric field or a current flow. This technology is already deployed in the car in order to darken the interior and exterior mirror and prevent glare effects. The disadvantage of larger surfaces is the high energy requirement needed to achieve short switching times.
Control is what counts most
The technology that prevails is not crucial, as they all need to be controlled electronically. The essential know-how is in the software and the intelligent connection to the vehicle system.
"Today, it is just a question of when intelligent glass is coming. At Continental, we use our know-how for the entire system and can therefore integrate the desired functions into our electronic control units. We adjust the algorithms so that the behavior of the windows offers maximum safety and comfort for the driver, while improving emission values. The appearance of all windows is optimized with an intelligent reaction to the changing lighting situations, as well as automatic compensation of temperature and aging effects," Wolf said.
Continental at CES 2016
Continental will be showcasing a demo vehicle with its "Intelligent Glass Control" technology at CES in Las Vegas from January 6 - 9, 2016.
Continental develops intelligent technologies for transporting people and their goods. As a reliable partner, the international automotive supplier, tire manufacturer, and industrial partner provides sustainable, safe, comfortable, individual, and affordable solutions. In 2014, the corporation generated sales of approximately EUR34.5 billion with its five divisions, Chassis & Safety, Interior, Powertrain, Tires, and ContiTech. Continental currently employs more than 208,000 people in 53 countries.
