Few security elements pass so unnoticed inside a car. However, they are a ally important to avoid distractions while driving and they are leading significant progress recently. We talk about the HUD, or what is the same, Head Up Display -LCD display frontally. The projection information directly on the windshield of the vehicle is not new, yes it is the way that information is projected within the field of vision of the driver. According to Continental, 2018 will be more than five million vehicles equipped with this system in the world, compared with 500,000 which is expected to finish this 2014. Currently up to 10 manufacturers offer this technology in a total of 19 models.
A little history
Although these systems are currently used in the car or in civil aviation, the first HUD They have their origin in military aircraft, to position the lens looks over the glass aircraft cabin. The first manufacturer who opted for this technology in a car was General Motors back in 1988. Ten years later, Corvette C5 rode for the first time a Head Up Display color. Since then, there are several brands that have joined this system, either as an option or as standard feature. And, most importantly, gradually it is becoming more widespread in lower segment models, not only luxury.
There are mainly two types of HUD. The most basic and economic consist of a transparent screen that is anchored to the vehicle dashboard, behind the wheel, in which information is projected. It is the case Peugeot. The French brand uses a small translucent polycarbonate panel located behind the instrument panel which also is concealable. Others, by betting higher segment models are "hidden" and you just know they're there when you cast eyes forward. The driver sees information as if Suspended above the hood of the car, a distance of about two meters, and not on the windshield. This is projected through the device hidden behind the instrument panel visor.
That project parameters vary with each manufacturer. The most common is speed, but some brands are committed to give other information such as the Browser indications, witnesses change or counter.
as an accessory
You can also take the HUD "Market Stall". In the market there are some Head Up Display Laptop, so that you can install on any model. Navdy It is one of them. It costs $ 499 and the first units will begin arriving in early 2015. It consists of a device placed on the dashboard and which is responsible for projecting an image to the bottom of the windshield. Connected to an application compatible with Android and IOS 7 or higher, allows interact with the phone, messaging, music, navigation or social networks with voice commands or even simple gestures, thanks to a camera. You can also show the speed at which circulates the car, the kilometers of remaining battery life (if it is an electric vehicle) and the level of battery charge, all thanks to OBD II port connected to the onboard computer of the vehicle.
Another solution is to download any iOS apps for smartphones, Android or Windows Phone. But they have two drawbacks. The first is that you need a stand to place it in the car. The second, and perhaps more importantly, viewing day is not optimal. They look much better circulating at night.
LED or laser augmented reality ...
And now the Range Rover Evoque and new advanced integrated laser Head Up Display system. This includes laser holographic techniques getting color saturation, brightness and superior contrast as compared with other systems. What the laser brings over previous-based LEDs, is a clearer and more accurate reading, even in sunlight acting directly on the windshield. It can be customized by enabling or disabling all functions, increasing or decreasing the brightness and adjusting the vertical position of the screen, all from the dashboard menu.
The next step, already underway, will be the augmented reality. Chambers will be responsible for capturing and "read" what happens in front of car, but these images may be supplemented with additional information such as the presence of pedestrians or cyclists, the distance from the vehicle in front, speed on the route section that circulate, the Detour signage we must take on the freeway or guide an alternate route in case of jam.
