In order to sense objects in the world around them, the cars ofTesla will no longer use Ultrasonic Sensors. It's part of the company's shift towards its camera-onlyTesla Vision driver- assist tech, which stands in contrast to the rest of the industry's reliance on a mix of LIDAR, radar, and cameras According to Electrek, the sensors in the cars are used for short range detection to help with warnings.
The sensors will be removed from the new Model 3 and Model Y vehicles in North America, Europe, the Middle East, and Taiwan, before they are sold around the world. The Model S and Model X cars will no longer have the sensors.
The shift away from Ultrasonic sensors won't affect the car's crash safety rating. Cars without the sensors will lose access to features such as Park Assist. The features will be restored once they perform equally well using the camera based system.
Last year, the company said that it would no longer ship cars with radar. The company will rely on its camera-based system for driver assistance features in the future. The New York Times reported last year that Musk had said that cars should be able to drive with cameras alone and that humans could only drive with two eyes.
The removal of radar last year resulted in temporary limits being placed on a number of features. The cars have either maintained or improved their active safety ratings in the US and Europe, and that safety features like pedestrian automatic emergency braking are actually better with cameras than with radar, according to the company.
The shift away from radar had some issues. There was a rise in reports ofphantom breaking, which is when a car's driver assistance systems apply the brakes because they mistakenly think the car is about to collide with something. The Washington Post reported that there had been a sharp increase in complaints to the NHTSA about automatic braking issues.
There is a diagram of the positions of the sensors on the front and rear bumpers of the car.
