Cruise Control - car keeps accelerating after releasing cruise lever

welcome!

the error is in holding the stalk up. the computer is registering mph increase faster than the car.
best thing is to use the accelerator.

this has been happening since the computer genius woz first noticed it and called the cops.

the real problem is translating japanenglish in your brain.

 

Is this the same problem Steve Wozniak experienced years ago?

yup, some people are too smaht for their own good.

 

Look at the speed the cruise control is set to, when you hold the speed lever, the speed number keeps going up, so hold it for five seconds at 30 mph and now it’s set at 45 mph
If you touch it once it goes up 1mph, but if you hold it it increases fast, the car speeds slowly until it gets to the set speed.

 

if it were a gto, it could keep up with the cc.

 

With DRCC, you actually set it to the km/hr or MPH you want. For instance, if you join a road and are in traffic with a speed limit of 90km/hr, you wind the stalk up to 90:



You could be driving at 50km/hr at the time, wind it up to 90, and it will accelerated to 90 unless a vehicle is in front driving slower, in which case it will sit in behind that car till you change lanes etc. If that car slows and you're still behind, your car will slow down even to a complete halt. To then resume when he drives off, you just touch the accelerator briefly, releasing it when your car starts moving - it will resume following the car in front.

Works perfectly.

 

Yes the DRCC is a fantastic bit of kit. I use it in slow moving stop and go traffic too as it saves having to ride the brakes all the time. Why not let the car take the stress out of driving

 

I'm now a convert and can't imagine driving without DRCC.. never thought I'd be saying that when I joined Prius Chat!

 

Please take your car to your local authorized dealer.

 

@Carolyn Belknap , before you go to the dealer, try again, but this time just tap the cruise control bar up with a quick flip. This would be more likely to succeed than a push, which could be held longer than is necessary resulting in the extra acceleration you had earlier.

 

I think it's likely working as it should.

But, the dealer's salesperson REALLY should have given instruction (or demonstration) on it's use before delivery - so checking with your salesperson wouldn't go astray.

 

How do you activate "resume"?

If you cancel cruise, and then tap up on the stalk once, is that resume? I don't use that function to speak of, but I'm thinking: won't that activate resume, try to haul you all the way back up to the previously set speed, fairly aggressively.



Apologies if this has been said already, haven't read right through the thread.

 

no worries, neither has carolyn.

 

Yes, it will resume, but "aggressively" isn't the word which comes to mind - more like "leisurely". Instead of touching the stalk, I almost always touch the accelerator and when the car starts moving, leave it to resume.

 

Is that + button direction not also labeled "Resume" ??

The tap to accelerate works as advertised ONLY if the cruise is already "set" and functioning.
Otherwise it functions as "resume" and will accelerate to the previously used speed.

 

Agreed. This is one place the Driving Mode selection makes a big difference.
