Column A is transparent – The unique idea pursued by many big firms is still inadequate
One point that anyone who has ever driven a car must agree is that column A, especially on large models with thicker A-pillars, obstructs their view of the two sides a lot.
If this area is liberated, the driver will have a viewing angle of more than 180 degrees that is completely open, but this is easier said than done considering the importance of column A in supporting the roof structure in particular. and overall stiffness.
When self-driving cars are perfected in the next 15 to 20 years, this problem is expected to disappear completely, although there is still a long way to go. General Motors seems to have considered an interesting idea in the past time to limit the A-pillar from covering the driver’s eyes, as shown in their recently discovered “transparent A-pillar” patent.
Specifically, the new A-pillar in GM’s imagination will have a not-so-small area (up to 3.15 inches wide, 15.7 inches high) made of transparent material made of synthetic materials to let people see-through driver.
In addition, the electronic system serving this area is also taken into account with a small current flowing through to help limit fog / ice from sticking, not to mention the ability to customize the transparency by amperage to limit the flow of electricity. Reduce glare in certain situations.
To compensate for the overall stiffness of the A column area lost because of the new material, other areas here will be reinforced with carbon fiber and the column structure will also change to a more solid, multi-layered form.
In fact, GM is not the first to think of transparent A-pillar technology when Jaguar Land Rover once rekindled this idea about 10 years ago. However, the ability of the US corporation to perfect this equipment compared to its British rival is significantly higher considering the technological advancements currently in the market as well as their investment budget.
