With the active wiper control program, you don't have to worry about the car when it rains.

The rain sensor on the car is very smart and useful. Its working principle is to irradiate an infrared beam from the car to the front windshield. When the glass is wet, the light reflected on the sensor will be reduced, and the sensor will activate and The control system turns on the wiper. However, no matter how smart you are, there are times when you don't make it.

Active Wiper Control Procedure Available in Rainy Days

Magnus Carlsson, head of self-driving products at Swedish company Semcon, said: "Most of us have the terrible experience of trying to overtake a heavy truck on a highway on a rainy day. In the process of overtaking, the rain splashed by the truck hits the windshield, which may seriously affect your vision. But in this case, the current rain sensor will not have any effect. It will only start working when it detects that there is already water on the windshield".

Now Semcon has developed a new type of wiper program called active wiper (PAW). The principle is to use the cameras, radars and rain sensors that are currently installed on most cars. When large vehicles are found, they are There may be sudden splashes, and wipers are prepared in advance. Use the camera to monitor the threat and use the radar to measure the distance data, combined with the information obtained, the wiper is adjusted to the maximum speed in advance.

The advantage of this is that you no longer have to worry about the windshield being covered by water, and you don't have to worry about losing your driving sight.

Carlson, who invented the technology, said, "This technology was not developed for heavy rain scenarios because the wipers have already been activated. The most appropriate use scenario may be when the rain has just stopped or drizzled, but there is still water on the road."

This function has already been evaluated by tests under real conditions, and the program is also easy to install in modern cars. This technology is very practical, but you won't be able to use it until after next year at the earliest. And even with high-tech escorts, driving on rainy days still requires caution.
