Title: 2D Bar Codes in Road signs
Post by Sam M. on Oct 23^rd, 2022 at 1:19am

Hey all,

I thought this was pretty interesting. Especially when you think about how many cars have cameras for driver assistance.

Yes, very interesting.

Lexus has been equipping some models with a "Road Sign Assist" feature since 2018 model year. I have seen a Lexus Road Sign Assist system misidentify an Interstate number sign as a speed limit sign (I-90 misidentified as speed limit 90mph).

Oh wow, going from 70 mph to 90 mph I am sure causes quite the scare. [smiley=shocked.gif]

Grant your example reinforces how important it is to get an accurate description of the complaint when it comes to these driver assistance systems. So often it is vital that the service advisor (or us as the technician if we speak to the customer) ask "does this issue happen in the same location every time?"
