What do you know and pay attention to Huawei's car? It is estimated that many people will say that it is through lidar.
Because Huawei believes that in the automatic driving technology, lidar is more advanced than the vision solution, and at the same time, it has stated that it will reduce the price of lidar to less than $200, so that everyone can afford to use lidar.
I have to say that Huawei's appeal is still very strong, with the support of Huawei, automatic driving based on lidar technology has developed very quickly, especially domestic car companies, which are on lidar and are at the forefront of the world.
There are even two factions of autonomous driving, one is the visual faction represented by Tesla, and the other is the lidar faction represented by Huawei.
Recently, the global CMOS sensor giant Sony also officially built a car, and exhibited two concept cars at CES 2022, a pure electric car Vision-S, and a pure electric SUV Vision-S 02.
Sony said that the reason why it wants to build a car is to bring consumers a safe, reliable and comfortable travel experience through its own CMOS sensors, solid-state lidar, sensor fusion and other imaging and perception technologies.
On the car on display this time, 40 sensors were used, and most of these sensors were developed by Sony, especially lidar, which adopted a new technology.
Specifically, one of the 40 sensors is particularly noteworthy, and that is the SPAD (single photon avalanche diode) lidar sensor (laser receiving chip) called IMX459.
Sony uses its own double-layer image sensor stacking technology, based on APAD technology, other lidar companies can use the IMX459 to create thousands of ultra-high-definition radars with equivalent lines, so that cars can see farther and clearer.
Not only that, but the double-layer stacked sensor has a new technical way to calculate the distance faster, which can make the car's reaction time faster, automatic navigation more accurate, and lower latency, which is the key.
We know that Sony is one of the world's top companies in cmOS sensors. The CMOS sensors on everyone's flagship phones are basically used by Sony.
Even if you use a visual solution, Sony is also very advantageous, coupled with Sony's self-developed lidar, this kind of technological innovation based on the underlying layer, it is not difficult for Sony to make a smart car.
Sony did not say that it can not build a car, perhaps just like Huawei, to help car companies build good cars? After all, Sony's self-development capabilities at the bottom, especially in sensors, are indeed stronger than Huawei.
