For The Sake Of Optimal Sensor Jobs, Hyundai Patents Cleaning Equipment For LiDAR

Hyundai Motor Group and Kia will soon present one of their most advanced technologies. They have just filed an innovation patent that allows cleaning the outside of the vehicle, including LiDAR technology. In addition, they are also developing innovations in the use of rainwater.

Reported on the CarBuzz page, Saturday, July 29, the two companies have submitted the technology to the United States patent and trademark offices. If the news is proven true, this will allay customers' concerns about the optical detection system on their vehicles.

LiDAR is a very accurate technology in detecting the environment and taking action according to the target object. This sensor works by using laser light to measure specific distances.

However, there is a problem when LiDAR is covered by dirt or water, thus disrupting the function of the sensor or camera. This problem is being addressed by this South Korean company.

Hyundai will apply for a compressor cooling system that can clean LiDAR sensors and operate them using rainwater collected on the car through a rain sensor that drives the wiper when it rains.

This technology will involve a rainwater collection unit that will flow down the front window, a rainwater filling site, and air compressor cooler. Interestingly, this technology does not require a separate cooling tank because rainwater will naturally cool the air compressor. By utilizing rainwater, this cleaning device will emit a burst of water or air to clean the sensor.

The rainwater collection unit will be installed under the cover where the wiper is located, with a fairly small and low design so as not to block the driver's view.

Hyundai is also considering the time to clear the sensor to match and not cause unwanted events, such as cleaning the lens while the car is receding which can disrupt backward visibility.

Hyundai's main goal in patenting this technology is to keep the LiDAR feature clean, functioning properly, and can be used anywhere and anytime.

Although still in its early stages, Hyundai has used this LiDAR technology in several vehicles to help drivers. The manufacturer under its auspices, such as Genesis, plans to launch the LiDAR feature on their latest model, the G90.

The advantage of LiDAR over a camera-based system is its ability to detect hazards in a distance of more than 3,200 feet, giving drivers enough time to avoid objects in front of the vehicle.
