Do Manual cars still have cruise control?

[Accipiter22]

I only ask since if you come to a hill or something an automatic will shift up as it works harder to go up-hill...does a manual on cruise control just read line the ish out of the car so you don't have to shift?

 

[The Sauce]

It will keep you at speed in whatever gear you you set it in. If you set it at a reasonable RPM then it won't redline.

 

[Scouzer]

You could probably stall it though if you set the cruise control, then kept decreasing the speed via the cruise controls.

 

[Colt45]

How do you figure it's going to redline it with the car in gear?

Theres no torque converter. Wheel speed is directly proportional to engine speed.



It might stall if you've got it cruising at 1500rpm and it goes up a hill, though.

 

[CrackRabbit]

Yep. My car is a manual with CC.
Works fine.

 

[Sunrise089]

My s2000 is probably the worst candidate for cruise control in a six-speed (no torque whatsoever), and the feature still works fine. I wouldn't worry about stalling unless you set it like an idiot.

 

[Don Vito Corleone]

The CC on my '84 Accord didn't automatically disengage when you pushed the clutch, which was annoying, but my Maxima automatically disengages when you apply the brakes or the clutch. I assume all modern cars work this way. I imagine it would also disengage if you somehow stalled the car with the CC on.

 

[DivideBYZero]

The CC in my manual car works fine. It simply applies more throttle wen you come upon an incline, just as you would if you were in control. I fail to see the issue.

I did, however, have a time when I was cruising in 6th at ~90mph, traffic slowed down to something like 55. I hit the 'resume' button while still in 6th to see what would happen. Well, it started to pull but then shut off back to manual throttle. I guess it must have some anti-labour setting to prevent undue loading at low RPM.

I hate using the CC controls with my automatic Focus because it causes it to downshift and do stupid sh!t that wouldn't happen if I was doing it myself. It's supposed to save you gas, not use more. :roll:

 

[cardiac]

I've had a few cars that would disengage the cruise if you dropped more than 5 mph..... So if going up a hill in 5th gear, and you slowed considerably due to insufficient power, the cruise would just kick out......

I wondering if he means if you set the cruise control at 65 mph, if you downshift to first gear and you hit resume, it might try to go 65 mph in first, redlining it.


But I see what you're saying, the way he worded it made it sound like it's somehow going to redline because it's having trouble going up the hill. That's the only thing I can think of.

 

[MrPickins]

I've never tried using the cruise control in my Ranger in any gear other than 5th.

Now that you've got me curious, I think I'll try out how it works in other scenarios

It won't matter. If in fifth, to do 50Mph you need 2100 rpm, then that is what it will stay at. No more, no less. If the same vehicle needs 3500 rpm in fourth to do 50 mph, then that is what the CC will hold at. End of.

So what if you're in first gear and hit resume?

Most modern CC systems will not engage below 30 mph. How often are you going 30 mph in 1st?

Bingo, but in the name of science tomorrow I'm going to set the CC at 80, slow to 40 and from second hit resume and report back.

You kind of missed my point there.

My point was whether the cruise control would rev the engine to redline trying to maintain the set speed. My example was if you you set the cruise control in a higher gear and then tried to resume it in a lower gear.

I just took my Z out to see what it would do, and it will in fact rev the hell out of the engine trying to reach that speed. I set it at 60 mph in 4th gear and then resumed it in 2nd gear. It climbed above 6000 rpm before I hit the brake to disengage it.

For the record, first gear will reach about 45 mph.

 

[GTaudiophile]

My 2005 Mazda3S was a 5-speed MT with CC. I only liked to set it while on the interstate in 5th. Otherwise never used it.

I got your point, I was just thinking that in practical terms it really shouldn't come up.

1st in my car is good for about 35-ish (45-ish in the Volvo, but that's an automatic), and second for a bit over 60, but it's just such a rare occurrence that it's really not something to worry about.

[DivideBYZero]

OK. I did the test above. I set the CC to a speed greater than 2nd can reach then hit resume. It ran right up to the limiter then shut off.

 

[TheNewbie]

CC is meant to be used only on a freeway (or otherwise a road), where you can maintain your (fairly high) speed for a while. Climbing mountains usually involves snake shaped roads which means you have to slow down anyway, so CC would disengage also on an automatic car.

Eh? It would not disengage. It's programmed to hold a speed, not detect how windy the road is.

 

[PricklyPete]

My 2005 Tacoma Manual V6 has it and I use it regularly. It has never had any issues.

 

[Pliablemoose]

Now for the real test, someone needs to go in reverse & press "resume" :evil:

Let's see if the M does over 30 in reverse then... :evil:
