Cruise control for my Xantia

[Mads]

I have bought at cruise control for my Xantia and are now planning how to best fit it. It's a "basic" vacuum type (Liteon AP50), and hence the control box is not too flexible, and requires a speed input of about 3000ppm or about 5000ppm.

It comes with a magnetic speed sensor, i.e. a ribbon with 1, 2 or 3 magnets for the drive shaft and a reader. The signal is then a pulse each time a magnet passes the reader. Unfortunately the sensor doesn't look too robust , hence I would like to steal a similar signal somewhere else. I was thinking of using either the speed sensor or the rpm sensor. Does anyone know which sort of output I would get from those sensors or any alternative ideas?

I see from your signature that you have a 2.0 petrol Xantia. Personally if I were you I would find a Xantia with factory cruise control and transplant it to yours.

I am looking into cruise control atm for my 2.0 HDi and therefore have a few more issues than you do. I have been told that from factory they were only fitted to or an option on 2.0 and 3.0 petrol Xantias. A Factory set up should be more robust and probably be more suitable.

Hope that helps

My 2003 Pug 406 HDI 110 has cruise control.Could`nt do with out it now .I wonder if it would be possible to use the parts from that,as there seems to be more 406`s with cruise than Xantia`s Toby Hdi.

Thanks for the tips, but I already got the AP50 in hand, and it was rather cheap (about £90) 8). From what I heard, it works really well; I'm just not too sure about the sensor and would prefer to plug it into something sturdier. If all other fail, I'll use the magnets but probably look at securing the ribbon more safely.

Finished installing my new cruise control 8) Got at couple of tips on the Danish forum, and actually it went pretty smoothly.

Connected the control signal to the ignition signal on the "ignition coil" (pin 1) (Tip from AndersDK ), which fitted the specifications on my low tech and rather inflexible device. After that it was pretty straight forward.. Power from the fuse box, abort signal from the brake pedal switch etc. If you consider doing this to a diesel, ignition signal is obviously no good, but there are plenty of other possibilities. I'm sure someone can help if you ask the right question!

Looking forward to a relaxed cruising to Austria later this winter. 8)

guys,

also thinking of cruise control. have any of you guys have it on a turbo diesel. Can it be done.

tq

For it to work on a turbo diesel it would need its on servo unit and to not use the intake manifold vacum for power.

There are kits out there for it but a bit of string looped thru the floor could do the same thing

I would love cruise control on my Activa.

Where did you get your kit from?

Would it be compatible with the Citroen stalk??

I'd want it to look as standard as possible.

Hi David,

The one I got, LiteOn AP50, is the lowest spec. there is. I'm not sure if it is compatible with the standard stalk, probably not, the more expensive electronic ones seem to have more options, also you can choose from a number of different stalks. Actually I'm thinking of getting one for my C3.

Bought the AP50 on http://www.jariauto.com/shop/fartpilot-136c1.html , (Danish site). Don't know if they ship abroad, but they must also be available in the UK at a reasonable price. Good luck.

The LiteOn AP series cruise controls are available worldwide. They are sold under a few other brand names too, but generally known by their type no.

The speed control signal can be obtained from several sources on a modern car :

1) ignition coil
2) speedometer sender unit
3) flywheel tdc sensor
4) ABS sensor
5) any proprietary speed signal found in recent cars
6) retrofitted magnetic coil sensor & magnets on a drive axle
7) in some cases the alternator charge lamp output (as stated in manual)

NOTE that an automatic car MUST use a direct axle/wheel related speed signal.
Also note :
A manual car fitted with axle/wheel related speed signal MUST use a clutch pedal abort switch.

A Xantia TD only have one option for the actuator type : the electric servomotor driven actuator. Because there is no vacuum source on a diesel Xantia.
Other diesel cars would have an electric or cam driven vacuum pump for the brakes servo unit, which is a perfect source for the cheaper vacuum CC units.

The stalk control is nothing but a set of normal push-to-make switches, housed in a nice looking stalk.
You may use a modified extra lights or blinker stalk, if nothing else suits your critical eye

The cheaper vacuum operated units are in no way inferior to the electric servomotor types. The electric type is simply more expensive to produce, and can be used in any type af car as a universal type. Hence the generel assumption that they are "better".

Just found this site from down under. Derek posts much better tips and manuals than the one I got with my CC kit. 8)

looks to be the same kit that is being sold by this chap here in the UK:

Hi Mads,
I am about to install an AP50 kit to my xantia hdi. How is it working on your xantia?

[Mads]

Hi aneesh84,

Sorry to say, I do not have my Xantia any more Changed it for a 2005 C5 MkII - weekend; nice car, but not the same class as the Xantia..

Well, I got the cruise control working in the Xantia, but to be honest, it was never very stable. I think it was due to a low quality vacuum source, but I newer got around to checking it out properly.

Hope your installation will work better; comfort wise, cruise control is a must on the longer rides, once you have one you will never again want a car without it!

BR / Mads

[aneesh84]

Oh! Then do you suggest it is worth the effort? Xantia hdi has a vaccume pipe for the EGR valve. Do you think it would prove a better chance for it to work properly?

Also can you guide me about how the output of the actuator can be connected to the throttle in an HDI setup? should i connect it to the potentiometer where the accelerator cable goes?
