Hi All,
perhaps discussed already (pls provide link..) but what is the use of this fancy system when the first snow falls it just doesn't work anymore?
I should at least keep "normal" cruise control without adaptiveness... but no! no fuctions at all anymore even the anti collision stopped working.
From full featured to NO feature at all.

Your experience?

Did you experience it yourself or just read somewhere? Some members here had trouble with ACC even in a rain. I didn't have any in downpour. We already had some snow, but not much - still no problem here.

I went across Austria, in very heavy snow a couple of weeks ago. Some time the sensor radar would get dirty, but it was snowing a lot, and very often it would clean itself after a while.
In rain I never had issues.
If you press longer the cruise control button it will go in to normal cruise, without the adaptive part, so you do have the option.
But it is very good. During the night, heavy rain, I was on ACC and I noticed the car slowing down and 2 sec after I see a dark color van with 0 back lights, the radar saw it before I did so it is a good safety feature.

This happened to me this weekend, but when I made a point of clearing all the snow from the area at the top of the windscreen (behind rear view mirror) it all worked ok.

For any ADAS advanced Driver assistant system to work all the sensors, cameras, radar systems must have a relatively clear & clean view. The lane deviation system needs to have road markings to be able to decide where the car is on the road. No white lines i.e in snow the camera has nothing to see and will disengage.
In the user manual it lists pages of reasons and conditions that prevent the safety systems working. The Car makers will always air on the side of caution and automatically disable the system when any part of the system can't see. This protects them from drivers simply expecting the car to stop. Even Tesla's autonomous systems fail in certain conditions, which is why before setting off you agree to be in control of the car, bit like signing T&Cs before driving off.

As leeloo said, hold the cruise control on/off button depressed for about 3 seconds you will enable regular (non acc) cruise control.

This works if the other systems go offline. Tested it my self during heavy snow.

And who protects me in a car that makes an emergency stop by itself with no reason? :mrgreen:
It's a good thing that the PCS turns itself off when sensors are dirty, but Toyota forces me to use it, because I can't turn it off permanently. Everytime I start the car the system is back on. That would be ok if it worked fine, but it doesn't. And when I turn it off, I get a warning signal in my display like it there's a problem.

Do you need protecting

This is the issue with all such systems, there's a cut off point where the car decides to stop or disengage the system, it's at that point the driver should always be ready yo take control.

In the case of the Tesla accidents 2 of the drivers are alleged to have been asleep and 1 is reported to of been sitting in the rear seats.

It's a open question if you switch the system off and then have a accident will your insurance pay in full or part if it's deamed the safety system would of helped or prevented the accident?

It's complicated.

When I cause an accident because I forgot to brake I'm the one to blame. That has nothing to do wether PCS is turned on or off.
But I wonder who's to blame when my car causes an accident because it brakes by itself with no reason and someone bumps into my rear end

Keep wondering I have my car now for nearly a year and all the sensors are working fine.

If someone bumps into your rear end it is always ther fault.

Not necessarily if someone brakes with no reason.
But I think we're going a little bit off-topic now. Sorry for that.

Off-topic, but I agree with Alexr. At least here according to rules, you should always keep a secure distance from the car in front of you, so you'd be able to stop if this car suddenly brakes. If you smashed into the rear of other car, it means it didn't keep the distance or pay attention to the road, so the driver broke the rules and it's his fault. The driver of the front car might be avoiding some animal on the road and there's no way to prove otherwise.

With other words.. dont reley full on the electonics of the C-HR but always on your own logic thoghts and a safety distance..

Let the electronics do their work and suggest/warn you.. dont drive with closed mind and trust on all electronic features.
They will help you in case... if they are in time... If not, please look better on traffic and drive more carefully!!

 

[icemangrmed]

It works flawlessly for me under heavy rain, both during day and night driving. It also worked fine under light snowfall.

 

[Spanner650]

Newbie - so apologises for what might come across as a silly question. I get the adaptive cc but do you have to be in cc mode for the anti-collision also or is this an all road/style of driving accessory..?

 

[holyhead]

Welcome to the forum.
If you not disable it yourself it is always,s activated with or without adaptive CC
