[Autohome News] Recently, according to overseas media reports, Tesla has applied to the U.S. Federal Communications Commission for approval of a patent for a short-range motion sensor to prevent children from being forgotten in hot cars. situation occurs within. The application of modified anti-theft sensors will further enhance Tesla’s anti-theft system, which is currently controlled by Tesla’s Sentry Mode. It is reported that this unlicensed millimeter wave sensor will operate at a higher power level, thereby more effectively protecting children so that they are not forgotten in the car, and it can also prevent thieves from entering the car and stealing. Getting permission to use higher-frequency bands is why Tesla needs FCC approval. Tesla's motion sensor device will use four transmit antennas and three receive antennas, driven by a radar front end. The technology is currently used in camera-based car operating systems, as well as in-seat detection systems that can record whether someone is sitting on a chair in the car. Tesla says it promises to be better than traditional rear-seat reminder systems because Tesla says the sensors can "see through" soft materials, like blankets used by children in the car. The sensors currently used do not have the effective wave intensity to detect human activity that is obscured by objects. The company also says the sensors can detect micro-movements, such as breathing patterns and heart rhythms, while also distinguishing between children and objects placed on the seats. The company goes on to say that the system can prevent false alarms and detect things that camera-based systems might miss. Currently, the sensors on Tesla cars, like other cars on the road, can only detect people who weigh a certain amount. This makes airbags slightly more dangerous for smaller passengers, which is why the Centers for Disease Control recommends that younger passengers not sit in the front seat of a car. According to the National Highway Traffic Safety Administration, 105 U.S. children died after being left in hot cars in 2018 and 2019, and 54 of those cases were because people left their children in the car. According to reports, the U.S. Federal Communications Commission is soliciting public comments on Tesla’s request to improve its sensor system, and the deadline is September 21.
