The update’s software code analysis revealed that Tesla uses Autopilot data to offer distance measurements to nearby objects on vehicles without ultrasonic sensors.

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]&#82… ...

This ultrasonic radar project is from [mircemk] who uses a small ultrasonic distance sensor attached to a rotating platform. A motor rotates it around a 180-degree field-of-view and an Arduino ...

Nevertheless, according to Tesla hacker @greentheonly, the 2022.40.4 software update has an interesting feature, allowing cars without ultrasonic sensors (USS) to offer distance measurements to ...

And ultrasonic sensors have been used in distance-measuring applications. Other common uses today include: Object detection and ranging in automated robots (e.g., self-guiding vacuum cleaner) ...

1. Ultrasonic sensing works like radar. A radiated signal is echoed back, and the time of transit is measured. The distance is then computed based on the speed of sound in air.
