Of course, when approaching an octagonal stop sign, my Prius dash displays the same sign, STOP on a red octagonal shape. But I live in Ottawa, and noticed that when driving across the river in Quebec, the same shaped sign with "ARRÊT" is not recognized. Presumably, if I were using the French dashboard, the reverse would occur. Which leads to the following thoughts: 1. Clearly the car is matching an image of STOP with what it sees. But in Quebec, stop signs can either have "STOP", "ARRÊT", or both. So what does the French dash do? 2. Canadian provinces use the "Manual of Uniform Traffic Control Devices" in traffic signage. So why doesn't Toyota allow the car to recognize all of them, or the more important ones?
Mine only rarely detects a stop sign. Of course I know that the driver is required to pay attention at all times.
The camera is helpful at times. It always seems to get the speed limit right. But it also can cause a dangerous dependency on it. The other day, I was cruising along, allowing myself to take my eyes off the road, trusting the driver assist, but when I looked up, I saw a vehicle ahead of me that had pulled over to the side, There was no shoulder, so I would have hit it if I hadn't seen it. There was no indication of any collision avoidance, so I likely would have hit it head-on. I'm admitting my mistake, so before you condemn me for it, showing your lack of character, just understand that it was a lesson well learned on my part.
tss 2.5 on our hycam often misses speed limit signs. at 70, i hope i've learned all my hard way lessons
The software really should detect a stop sign on shape and colour alone, even if it can't translate. I had a discussion with a friend the other day who insists that the Prius doesn't rely on its cameras for that anyway, but uses a built-in map showing where all the precise locations for signs and lights are. I don't believe him.
It uses both. And sometimes they fight - if it sees something contradicting its map it will show it, but has a tendency to go back to its map info if it doesn't see enough repeaters.
Another thought - mine usually doesn't show stop signs, but that's because the main display never shows more than one sign, and speed limits take priority. So the only stop sign I normally see is on a little side road where it doesn't show a speed limit. That might be OP's situation. A little 'stack' border appears to hint there might be more than one sign. To see them you need the driving assist screen up, then the road sign display moves over to that half of the screen and will show more than one sign.
It's just an excuse for sketchy AI driving software; "It's up to the driver to take control at any time." So what good is it if you can't rely on it?
