Lane keep assist does not work in heavy rain
Passing it on. Ran into some severe downpours last weekend in FL the lane keep assist stopped working until the rain eased a bit. .
|
It uses a camera in the rear view mirror cluster to see the lines, I'm always kinda surprised how heavy the rain can be before it stops working.
|
How heavy? Between the rain and road spray barely able to visually see the car in front with tail lights on. I was keeping a safe distance visually. I think, but not sure even the distance keep assist stopped working too. I have never seen deluges like that in my life.
|
It also doesn't work in good weather on local roads at least 60% of the time.
|
One reason I didn't go for the full suite of DAP stuff. Up here, 'lines on the road" are sort of like UFOs. Some people claim to have seen them, but there is precious little evidence of their existence.
|
I've driven probably 20,000 miles using the lane keep assist between the S5 and the Q5 in all sorts of places and found it to work well and most of the time. (even a lot of time in vermont, although more like southern-mid VT)
It's significantly better than the implementation in mercedes, jaguar and toyota, from my personal experience. |
Excluding major highways, it often does not work on the roads in my area because groups of plastic reflectors are used to delineate lanes, not painted lines.

I've seen it simply stop working even on roads with very clear lines. It has a mind of its own.
On the VW Golf mk7.5 they have hacked the system to have that one camera in the mirror cluster drive the entire car all the time. |

It's not an autonomous driving system, its lane keep assist. I'm fairly certain the times it stops working on easily seen lines are because it is about to violate a regulation for how much self driving the car is allowed to do without more sensor's or government certification.

I have it set to Early. Anyone else notice the car is right side biased? When on highway it tends to like to hug the right line. It's rather annoying. I think it has always been that way but it feels even more pronounced now since I got a calibration a month ago.

our 2018 A5SB lane departure warning works well in all weather.
It doesn't have a lane assist capability like my M540i but that doesn't work all that well either. It's one thing to warn of lane departure, quite another to maintain lane centering without wandering left to right.

No complaints so far with nearly 30k miles. I normally disengage lane assist when the roads are drying. The system gets confused with the varying marks on the road.
any time I reach 45mph, the system kicks in as expected. The car turns to maintain the lane into curves. Sometimes I wonder am I not centered enough and the car is correcting, or is the system over correcting. The car has avoided drivers shifting into my lane or prevent a collision when attempting to change lanes. Actually, I hate when the car goes into avoidance when attempting to squeeze into a small opening on the highway. |
