Cruise Control In Wet Weather

[Fat-Tony]

ive observed my speedo whislt wheels are spinning in the wet, I was at a slow speed in second gear at high revs and the speedo was sitting above 100km. The speedo moves when the wheels are spinning so I cant see why the CC cant pick that up.

that one comment captures exactly why the CC wont cause the car to oversteer. the cruse only holds the car at speed and if the drive wheels loost traction the CC cuts power straight away to keep the speed correct. the worst the CC will do is make the car understeer but that's another story.

What if t/c was set to off?

it wouldn't matter because as the drive wheels break traction (where the TC normally comes on) the CC cuts power anyway because the wheels are going faster than the set speed.

slightly off topic:

can you guys remember the thread about the plane taking off on the conveyor belt? this thread is giving me that kind of feeling, only this time it can be proven.

I have created this new topic to inform all of the dangers of using CC in wet or slippery conditions.

The claims dept have informed me about this issue.

If you leave CC on in slippery conditions you are more likely to have an accident if you aquaplane as the rear wheels will loose tracksion, the CC will kick in reving the engine to maitain what the CC was set to.  As in my case, around 105klm.

So the rest is history,  refer to details of my car accident

you stated in your other topic u had TC on... so how does that support the CC incident causing the accident?

yeh good point. I've always though in a bid to get cruise control smoother (not so jerky as it applies throttle), when your travelling at the above set speed (say down a hill), and then slowing down again, the cruise control will come on in slight incremements as you approach your speed again, until it reaches the set speed, then applying the correct throttle to maintain that speed.....

never-the-less, I think that in the case above, CC was on, but because he accelerated manually and lost some grip, and it was all a passenger ride from there on in....

I use cruise control all the time in the wet - did so with the last three Fords I drove which incidentally all had DSC/ESP = the last two were autos (including a BF XR6T with the ZF box). This was never an issue.

At the end of the day, cruise on regardless of whether TC/DSC is on or off and regardless of whether it is wet, dry, hailing, sleeting, sunshine, dirt, tarmac, bulldust... it comes down to:

DRIVER IS IN CONTROL OF VEHICLE

If you aren't you shouldn't be behind the wheel. As a capable driver, you can disengage cruise with your right thumb on the steering wheel... before you apply either the accelerator or the brake. If you are going into a corner too fast, you can either disengage the cruise, brake or trail throttle with a gear change into a corner.

An alert and capable driver should be able to assess the driving conditions and determine what is a sensible speed to drive. If there is enough water to aquaplane at 105kph then whoever is driving should be able to figure that one out and slow down...

Blaming the cruise and t/c is like suing a TV company for being obese - you choose to drive at a speed and well if you want to play chicken and absolve all responsibility for judging your own speed get a mobility scooter.

DSC would have avoided the accident all together by correcting the slide. This is the sort of situation where DSC is the best safety feature you can have to keep to heading in a straight line and not sideways.

What a loadof crap, he had an accident and CC was not to blame. The only way you could crash is if you were going to fast arounda corner and the car slid and whether you turn the CC off or not would not have mattered. You were going fast, your momentum is what caused the accident and not the cruise. The cruise would have maintained 105kmh through the bend and if the limit of adhesion was at 90kmh, then you would slide out. The back wheels would have stayed at 105km/h through out the lside if it was on, however, tractionc ontrol would have sensed the front wheels traveling slower than the rear wheels and cut the CC and cut the throttle. The slide would still continur because your momentum is sailing you along. End of story.

I drive a ute, no TC, leaf springs and no amount of slippery roads causes the CC to make the rear wheels spin out of control. The only thing that would make the car crash is if I was goin to fast around a bend in slippery conditions and the car slid. Momentum woul dhave cuased the slide, not CC. The slide woul dhave happended if I was driving with my foot on the throttle and backed off, because momentum woul dhave carried me over.

At the end of the day... an accident involving one vehicle is primarily because of driver error. Blaming cruise/traction control is a cop out.

DSC may have helped... but if you go into a corner 30kph too fast then DSC can't defy the laws of physics - too much momentum and you are going to be off in the mulga.

The best traction control system is mounted on the end of your right leg and is connected to a powerful cognitive processor. It's your right foot if your brain engaged...
