1, laser wiper
Tesla disclosed a patent "laser wiper", the purpose of which is to realize the function of laser automatic cleaning of windshield dust. After creating a new neural network "deep rain" for automatic wiper, we began to consider replacing the traditional wiper car design with laser. Earlier this year, Tesla submitted a patent application entitled "Pulsed laser cleaning stains and photovoltaic modules on automotive glass products". If your tongue is not neat, you will be fooled by the name. In short, it can clean automobile glass with laser, but its application scope is not just windshield.
Step 2 emit a laser beam
According to the introduction provided by the patent inventor Tesla expert Feroze Dahl, the cleaning system involved in this patent includes a set of components capable of emitting laser beams, which can cover a certain area of automobile glass. The detection circuit can monitor whether there is dust in this area, and automatically adjust the parameters of the laser beam emitter according to the results to ensure that it has enough exposure time to remove dust.
3. Cleaning scope
From the published patent drawings, it is not difficult to find that the possible installation position of system components is under the front shell of the vehicle near the front windshield. Two air outlets are designed on the front shell, which are similar to those of the traditional wiper system. Instead of spraying water, it is sprayed on the laser. Tesla officially explained that in addition to cleaning the dust on the windshield, it can also automatically clean the dust that affects the vision of the camera of the autopilot system.
It doesn't seem difficult to install such a laser cleaning system on Tesla models, but as for whether it can replace the traditional wiper, there is no substantive conclusion yet, and it will take time to test.
