Can Tesla read speed limits? What does the second border with a gray border mean? [answer] • CARS

With the Volkswagen ID.3 semi-autonomous driving system, the question arose about Tesla's ability to recognize speed limits based on conditions. We decided to check out the thread to answer the question of whether the new Tesla can read traffic signs and to add some curiosity to the new feature - dual speed limit display.

Recognition of cars and road signs, including speed limits

Tesle Model S and X computer with Mobileye (Autopilot HW1) can read speed limitsalthough, as reported by our readers, this is not an ideal operation. Mobileye computers officially disappeared from Tesla production in October 2016.

It was then that new hardware platforms, Autopilot HW2, Autopilot HW2.5 (from August 2017) and finally Autopilot + FSD 3.0 (March / April 2019) began to hit cars. They have been catching up with Mobileye software for a long time. The ability to recognize and label the world was one of the key elements of their development, Musk said.

Stop signs and traffic lights understand cars from October 2019, from April 2020 they can respond to:

When it comes to reading speed limits, cars probably use map resources (Google?) And their own visual identification systems. This is a sensitive issue because by 2030 Mobileye will have patents for sign reading systems.

Od 2019.16 firmware (May 2019) Tesla had to distinguish conditional speed limits (source, character example). However, over the next several months, this feature could be overlooked. We link the first mention of an additional greyish speed limit from Q2020 2020. In July XNUMX, the feature was definitely already in Europe:

Tesla Model 3 announces a speed limit based on road conditions. In normal weather the limit is 70 km/h, in fog it is 50 km/h (c) Nextmove / Twitter

Speed ​​limits in localities in Poland. Up to 60 km / h at night, up to 50 km / h during the day (c) Reader Bogdan

Neither the 2019.16 firmware description nor the witness statements show whether the vehicle complies with the above restrictions when using cameras or presents them based on maps or its own database. The behavior of the machines shows that we are dealing with the second option (loading data from maps / internal database).
