VHPA v3.1.4 [updated 26/03/10]

[DeadWolfBones]

You can, however, use LFS with patch V and use LFSTweak. Don't ask me how, though... I've never bothered.

[Bob Smith]

You cannot use VHPA to put cars into the LFS. That is not it's intention. I'll merge this with my program thread.

I cant open FOX setups.

Hi Bob, I have just tried to install VPHAv3-LFS onto my Vista install.
I am getting a COMDLG32.OCX error which I presume is due to not having the VB run files, however when checking OS versions on the VB6 download page there is no mention of Vista support.
So can I just install them onto Vista or is there something else I need?
Any help would be appreciated.

[Bob Smith]

The VB6 runtime files are included by default on (I think) Windows 2000 and later, so Vista shouldn't need them.

What it will need, however, are the additional VB6 component files, available directly from the VHPA downloads page. Installation instructions are included in the zip but let me know if you can't get it to work.

In other news some people might be pleased to know I'm itching to get on with the next version (although from the perspective of anyone who followed the development process up until now, most of the major and most exciting work has already happened, but there is still some worthwhile stuff to be added).

[flinty72]

Thanks Bob, works a treat

[Zohan]

I can't get this program to run on my Vista system. I get this message when I try to run it.

"Component 'mscomctl.ocx' or one of its dependencies not correctly
registered: a file missing or invalid."

Anyone got a solution?

thnx for your help.

Read the FAQ

[lrdbsi]

hi this looks great but im having few issues.

theres no basic instruction how to activate this program with lfs

theres instructions how to setup / use the program but nothing clearly
indicating how to inject it into lfs to actualy change values.

what version of LFS does it work with,

the website has only 2 words even relating the program to lfs,

please help, thnx

There's your problem just kidding, as I'm sure Bob will tell you this isn't really a LFS tool but rather a true, real life car analyzer that just happens to work with the LFS cars 'cause the physics are so darn good.

[lrdbsi]

no cause the values are lfs vallues,

anyway i made a setup? which im guessing the prog does)

put in my setups folder and loaded it up in LFS

the suspension etc, was modifyed just as i had done in the editor.

but when i changed the engine stats ,, i.e KW/@XXXXXRPM or gears etc
no diference when in LFS

so the suspension works .

how to make engine change ingame, ??
thanks

There is no activation of anything.

what version of LFS does it work with,

-You can load LFS setups to it.
-You can save configurations as LFS setups.
-You cannot change anything in VHPA in such a way that it affects LFS in-game, if you cannot already make that change in-game.

Best way to use it (imo) is to obtain values using VHPA and then manually apply them one-by-one into your LFS setups and then fine-tuning.

the website has only 2 words even relating the program to lfs,

VHPA is not specific to LFS, so this is expected.

Because by default an LFS profile is loaded. This doesn't mean it's the only thing it is good for.

VHPA is not an LFS setup maker. It *can* be used for it, but VHPA is what it says it is: Vehicle Handling and Performance Analyser. That means any vehicle which VHPA allows you to make a profile for, LFS car or not.

put in my setups folder and loaded it up in LFS

All the settings that you can change in-game can be changed in VHPA, and will load correctly in LFS (patch Y, afaik). None of the settings that you cannot change in-game that can be changed in VHPA will load correctly in LFS. That is to say, you cannot change LFS car specs using VHPA. I just checked that gearing works just fine.

[lrdbsi]

thanks i learned more now than on your website,

may be good for newbs like me, if u write up q's and a's

I'm not going to explain in this post what it does, just download it, have a look, and read the manual. It should be crash free. Use at own risk, etc. I have also made a collage of all the different screens in the program [now quite outdated].

Good morning,

Please someone knows where I can find the program VHPA (introduction to vehicle dynamic) in Portuguese, or has option of choice languages

Att,

pjuniorbra

[Byku]

Now VHPA is only in english.

[Bob Smith]

I'm still planning to add language support back into VHPA. I need a better system that what I used for GRC2 though. More importantly I need to dust off the source (not done any programming at home for months), get it matched with patch Z and finish off all the other features I've started for v3.1.3.

Once my car is starting again, the karting meet is out of the way, and I've moved house (all this month), I should have time on my hands to get the ball rolling again.

[ACCAkut]

Thats good news, I'm waiting for a new version. Atm I think VHPA works best for the GTRs ( hmm, neutral setups), it seems to have some issues with the small cars, like the XFG, it seems to have a wrong limit for the spring stiffness. Only halfway through the slider is already above the ingame limit

[Bob Smith]

The slider limits do not adjust on a per car basis. I didn't see the point of collecting, storing, applying, and updating all that info. TBH I can't see it being an issue during normal usage as the limits in LFS are pretty generous.

Good morning,

What does the color on the graphics VHPA 3.1.3

Black - Blue - Red - Green

We must work to achieve what color, what color ideal for whether we are on the right path to examine the car.

Att,

Pjuniorbra

[Bob Smith]

If you can specify which graph in particularly you are referring to, then I can give you an exact answer.

If you are talking about general text colouring, or the colours used in balance diagrams, then blue indicates understeer, red oversteer, and green (approximate) neutrality. Note that green isn't necessarily best. VHPA can't tell you what will be perfect for the car, but how certain settings influence the car, so that you can better judge how to adjust a setting to alter the handling in the way that you desire.

[dihosdl]

Something wrong with homepage?
Is there someware else I can download the latest version?

/diho

[Bob Smith]

My sites have been down for over a week now. My host is aware of the problem. Really hoping it won't be much longer now.

[Medys]

Hi, could somebody send me the program? I could put it in my server (https) so others can download it too.

[pjuniorbra]

I can not reinstall the VHPaes Windowns 7, he sent me the following message - Component CODLG32.OCX or one of its dependencies not correctly a file is missing or invalid.
Help me.

"Error "Component 'filename' or one of its dependencies is not correctly registered: a file is missing or invalid"
You require the additional VB6 controls, available from the downloads page.
Make sure you read and follow the instructions included in the archive."

[Bob Smith]

I've only been arsing about with this update for a year and a half. I thought it time to release what I've got done so far.

Physics: Added modelling of drivetrain inertia (using fixed engine inertia for now)
Physics: Improved engine friction torque curve
Physics: Engine brake reduction now works by applying throttle to counter act engine brake torque, so fuel is burnt
Physics: Vehicles now get lighter when they burn fuel, and centre of gravity shifts appropriately
Physics: Vertical load on each tyre now comes from the dampers as well as the springs
Physics: Added dynamic caster angle that varies with body pitch
Physics: Fixed damped suspension deflection to include ARB effect
Physics: Improved clutch logic for fasting pulling away (now limits input torque but adds loss while slipping; used to just scale the input torque)
Physics: Differential settings now influence engine torque reduction to tyre traction limits (during acceleration simulation only)
Physics: Improved tyre temperature vs friction curves
Analysis: Added live damper response graph (shows suspension response from static condition to live state)
Analysis: Added level ride frequencies to springs analysis
Analysis: Added level ride form to adjust spring stiffness to create level ride (with three options; stiffen, soften, and average)
Analysis: Add rebound:bump damping ratio to damping analysis
Analysis: Added brake and brake balance to list of available deceleration graphs, as well as all graphs previously available for acceleration
Analysis: Added throttle to list of available acceleration graphs
Analysis: Added custom searches to deceleration analysis
Added support for Volkswagen Scirocco in Live for Speed
Added support for ABS in the setup
Removed dyno engine button, this now happens automatically, so long as input data is valid
Switched to using ABS and TC settings from the vehicle setup, removed duplicate options from user preferences, and the live view now respects the TC / ABS settings too
Deceleration testing can be indepenently configured to use the brakes or engine braking
Engine data table is now resizable, and displays 1 extra decimal place precision on output figures
Engine data table now has column for engine torque as percentage of peak (normalised torque)
Added intermediate time step option to acceleration run (500Hz)
Added belleville stack calculator
Added more car data links
Relaxed some vehicle input parameter limits
Fixed suspension deflection calculation bug
Fixed infinite loop bug in wheel inertia calculation, much faster algorithm now too
Fixed live longitudinal accelerations components not summing to the correct total
Fixed loaded radius being displayed instead of rolling radius (circumference value was already correct)
Fixed crash when cancelling the file dialog box in the vehicle auto-loader
Fixed acceleration loop cutting out prematurely after a gear change
Fixed crash that would occur if engine data table started at less than the engine redline, and the redline was at less than peak power
Fixed crash that would occur if engine limit rpm was set to less than engine idle rpm
Fixed incorrect tyre compound data being used on startup
Fixed suspension push graph not resizing with window
Fixed vertical scale lines on distance vs time graph
Fixed initial spring and tyre loads during first frame of deceleration calculations
Fixed missing tyre slip ratios in deceleration CSV outputs
Fixed incorrect loads on the tyre contact patch when spring motion ratios are in use (meant vehicles could decelerate, and potentially accelerate, too fast)
Fixed incorrect steering analysis when first selecting a vehicle
Fixed some vehicle data values slowly decreasing due data truncation after internal unit conversion - values are now lightly rounded
Fixed incorrect longitudinal CoG position displayed in pitch diagrams in drag race window

Neat. Thanks Ben .

[NotAnIllusion]

What bat file, and what are you copying to system32? If you're missing a runtime dll, putting it in the same directory as vhpa.exe should work.

[NotAnIllusion]

My internets are so slow atm I can't search for shit, but Google vb6 runtime dll or go to http://support.microsoft.com/kb/290887. Should install fine if you right-click and run as admin, certainly no need for weird bat files afaik.
