If ADAS systems don't work in heavy rain, it means it's working perfectly.

Hello everyone, I saw an owner problem of wapcar today, which means that Honda sensing will not work once it rains. I read a lot of comments and said that the system is not perfect or anything. As an IT enthusiast, I would like to say that in fact, this just shows that Honda sensing is perfect in design and function.

First of all, let me talk about why Honda sensing doesn't work when it rains heavily. This involves the perception scheme adopted by Honda sensing.

Honda sensing adopts the sensing scheme of monocular camera + microwave radar. Cameras are the same as our mobile phones and cameras. The camera transmits the captured image to the processor in the car for judgment. When the processor can find the white line and road traffic signs in front, LKAS (lane keeping assistance system), RDM (Road Department migration) and TSR (traffic sign recognition system) can be triggered.

But what if we cover the camera with water? According to our life experience, we can know that the picture taken by the camera will be very strange, the picture taken will be very strange, and the processor in the car can't process the picture normally.

Microwave radar calculates the distance by transmitting and absorbing microwave and time difference. ACC (adaptive cruise control) needs microwave radar to detect the range. Unfortunately, rain also has an effect on microwave propagation. Water can absorb microwaves and emit heat. This is the principle of microwave oven.

The failure at this time shows that Honda sensing can know its own limit and prompt the driver when the environment does not have the recognition conditions, which proves that the system is perfect. It's like a waterproof watch. When the system says that it can only resist 50 meters of water, you can dive 100 meters down with it. If it breaks down, it's definitely not a quality problem.
