Cars Ford Transit 2005 (WIP)

any updates on the project?

garyjpaterson · May 21, 2017

'Fraid not, nothing significant anyway. Been busy with some other stuff. New wheel etc doesn't help either, been doing a lot more driving in AC rather than modding lately, hopefully I'll get back to working on it soon.

With the improved AI I look forward for some van races

Why the two 'sad' ratings for my above post? Sad that I'm actually enjoying AC?

I'm not abandoning this project, I'm just doing other things for a while. It will take a while, but rest assured it'll be as good as I can make it.

probably sad because no improvements or updates have been made, we're all wating to smash that transit van into the ring

Fat-Alfie · May 26, 2017

Absolutely. Sad only in a selfish way. We have such talented people on this forum, making such amazing things. When someone like you (Gary) takes a break from modding, it's like I am being forced to go on an AC diet, with nothing but salad to look forward too

Does Sidewind steer it ?

Haha, it does actually! But I'll redo a lot of my aero stuff on it when I get more accurate data from the CFD, right now drag/lift are in the right ballpark but the sideforce stuff with the Fin is completely guesses by me at the moment.

Just checked just now, its actually hugely unstable in a crosswind, although I think there may be a bug with the way its implemented (wind that is, I'll look more into it).

Wind might make it more necessary to position the 'body' wing correctly forward/backward, driving in no wind only its height mattered but when it's coming from the side its position relative to center of mass is important.

The first post is one year and one day old now

Indeed, and the first post on the AC forums is probably 2 years old.

Bit busy at the moment, will get back to it I promise.

Absolutely. Cross-wind stability is all about the relative positions of the centre of mass and the centre of pressure giving a turning moment. An empty van will have all the mass close to the front but the centre of pressure will be a lot further back.

Just a quick update, new live axle code working wonders on this thing, really feeling much more natural in all aspects - braking and traction most noticeably, much less rear locking (despite front bias) and no more crazy inside wheelspin at every opportunity. Definitely have to manage understeer more, but thats to be expected.

@Stereo I tried messing around with LEAF_SPRING_LAT_K, but felt it just gave weird lateral oscillations and allowed a fair bit of lateral movement even with high values. Instead I just added a 5th link as seen below, seemed to be a lot better.

garyjpaterson · Jun 24, 2017

Pasted the new bits onto the S2, working well there too! Again, much more predictable and natural. Tendency to understeer, obviously offset quite nicely with the V8 pedal.
