(PS4 Controller) Annoying throttle and break issue
Hello
I started playing ATS after a long time again, I set my Controller up and started the game.
Here the problem started!
The game sees the amount of input but doesnt work right.
I press 10% throttle but the truck ingame goes straight to 100%, same with the break I press the break slightly but the truck goes to full break.
That extremely rouines the game for me.
Does anyone know how to fix this?

same thing with the xbox one controller as well let me now if you find help

Braking intensity can be changed with a slider in Gameplay options.

However, issue stated by you sounds like your controller works in DirectInput mode as this doesn't allow triggers to work as axis but only as buttons.

Two possible solutions are: Choose the right input device in game control options, although I cannot tell you what exactly will be displayed. Afaik the PS4 controller needs some emulator software to work with PC. Check it if there is a) an option to switch between XInput and DirectInput or b) another option to change triggers' operation mode from button to axis.

Edit: jcarder36 posted before I finished. Did both of you calibrate your controllers in Windows?

Well, I can say this, for the brakes, on real trucks when you press them they engage at 100%. There is no brake fluid in a semi truck braking system. And Air compresses because it is not a solid. So when air pressuer is present, it unlocks/opens/disengage the brakes. When you apply the brakes, your pushing on a switch in which just like the parking brakes, shuts off air supply to the brake system as well as dump the exsiting air pressure causing the brakes to lock.

Once locked/closed/engaged you have a brake lag that slows the truck down. In real trucks you can not just press the brakes and it just stops like a car. At speed you press the brakes and wait for it to stop, all it will do is create enough heat till the wheels catch fire or brake fade. Now there is no stopping.

Trucks rely on the use of down shifting gears mixed with the engine break mixed with the brakes themselves. In this mix the truck will stop, I have real brake thingy checked and the intensity all the way to the left and I can stop. Problem is in H-shifter mode, the engine break light gose on, but really it is just for looks because it dose nothing. I think the developer is confused what the engine break dose, it is the same in EST2.

Real truck throttles are nothing but a button under the pedal just like the breaks. Usally the governor setting or retarder helps for speed control, for some reason again dose not work in the H-shifter mod, and once again I think the developers are also confused. Mainly that automatic or regular gear box has no bearing on a truck having or not having a Engine break or retarder since they apply these to the automatic trans when they are really engine parts and were set up to begain with for the manual trans anyway..

So really for the most part between brakes and the throttle sounds like it is working right..
But like what randomisator said for the brakes, set the slider for the brake intensity to the right. This should make it stop like any car.. It dose in EST2...


Thank you for the interesting answer.
I drove many Trucks in my life (in Europe tho) and its different over here.
You are right the brakes arent carlike but we can controll how fast the air gets into the breakes.
The throttle over here is the same like cars (you step on the throttle you gett full response if you just slightly touch it the engine goes slowly. Maybe thats what confused me? But i see that ETS2 does the same thing! The throttle in European Trucks is Proportional unlike ETS2.

No problem, I can not speek much of issues and what is right or not by the developer in EST2, I have no exeperince in any European made truck in the states. I just only know how things are done in US trucks.

Like the H-shift+clutch in this game. It is all wrong, I just do not remember anywhere that you shift 1L then hit the gear set seletor for 1H and so forth. Maybe for me back in the day it was because it was a road ranger trans, who knows. I just remember it being first gear box select, first gear set select, then shift 1, 2, 3, 4, second gear set select, shift 5,6,7,8, then gear box split to second gear box, then first gear set select, shift 9, 10, 11, 12 and so forth.

I had to mod the "gearbox_layout_eaton_18.sii" file itself to fix this issue so it dose this. Now it is correct.. Matter in fact I also did this to the "gearbox_layout_zf_16.sii" in EST2 because I keep getting all messed up with this go to "L" and then "H" and then "L" and then "H" stuff. I do not know if it is they got confused with the picture of the layout, or European trucks really shift like this, so they asume all trucks do...

But I fixed that for myself, and I am good with this..

Well idk about US Trucks because ive never driven one but they messed it all up.

Theres a few different kinds of transmissions over here in Europe.
The Shiftpattern scs made is pretty rare tbh.

Idk about new Trucks because i allways drive old ones ... even tho im young xD (old ones are way better to drive in my opinion) but the old ones shiftet just like you said and theres maybe two new trucks without a automatic gearbox. SCS fked this a bit up and the non proportional throttle/brake is not right too (at least in ETS2). I know for a fact that US trucking is completely different from EU trucking but i cant imagine drivig with no Throttle controll xD. Its impossible to get on without it over here, in fact Throttlecontroll is key to be a good driver over here. Anyways il search for a way to get the Throttle/Brake to work how i need it to cuz i cant drive without them xD

Lets see how far i will get xD

Did you assign an axis to throttle and brake in the Controls menu or did you create a bind for them under Keyboard?

I deleted my last post and started digging into, since I been out of the drive for a long time do to my health. Ok, being that it has been awhile for me, I did do some looking into...

On the counts of what I stated before about the throttle and brake being more of a push button control under the pedal in a real truck of course has always been correct like I said.

-->How ever... today I went and contacted some buddies of mine that still dose this. According to them Tech has caught up with the times. So the 13-15- and 18 speed trans do shift the way the devs set it. And yeah, the old push the pedal to the button thing is no longer on the newer trucks, they are travel control instead. Both. Brakes have a control of the air pressuer that is like the trucks in EST2 to control how much break is applied and the throttle can also control the amount of throttle you use.

Is the game correct in the current settings? All I can say now is, if it is simulating the old system, yeah, it is fine. If it is set to simulate the modern US truck, no, it isn't, and would need to be set up like in EST2.

Dose the "real simulated air brake" function work when checked? No, not even close.
It dose not simulate the fallowing... Air brake pressuer loss, brake fade.

Like I stated before, when US trucks need to stop, they do requier stopping distance and the use of the gears of the trans and at times the enging break. For example if your going 55, it will take about 450 feet until you stop. It is what it is. And this is for real, not the game. The engine brake is not availble on H-shifter when the j-brake is a "engine part" and used regardless what trans was in there. J-brake been on trucks with H-shifter trans for years..

In the automatic it may feel like it stops kind of like a car, but that is because the game automatic trans dose not really do the down shifting were the real trucks with automatic trans do. Its like down shifting the H-shifter but automaticly, going up or down. In the end, H-shifter or automatic has no bearing, holding down the brakes will cause brake fade, renerding them useless, or you will loose air pressuer.

In the game I can have air pressuer all day long pumping the brakes, and if some how I get to finally loose enough, the light shows, but there is no warning alarm, which is requier by DOT law to be on the trucks.

I am looking at this form and @60psi the light should go on and the alarm should sound. But no alarm sounds. The dev's must have decided not to use it. I remember in EST2 when you sleep, pending how many time you did so, if you started the truck up, you had to wait for air pressuer to build before leaving, which is correct too. I am suprised that they removed it.

In the end it still gose back to stopping distance, and the use of your gears. The engine brake also seem to be a importaint role, mainly going down mountains. I have no ideal why the devs placed differnces between H-shifter and auto trans, because no one sees anything differnt except one is auto and one is H-shift.

-I wouldn't know how to set for the throttle part, now I understand times have changed, so really I am with you in this now.

I do know I am not a fan on the performance of the trucks, the player truck useing the H-shifter is a real peice of work. You got the best engine, and it lags about below the speed limit half of the time. Don't these guys even know once again, H-shifter or automatic has no bearing what so ever in this? Under DOT law I would be fined to death for driving such a slow truck on the road. I would be carring a light load struggling at 35-40 mph and some AI fly pass me carrying a heavy load..

-My brake setting is set more for the stopping distance issues like in real trucks bro. So I down shift to help me. And I am also using the G29 PS4 wheel set using the H-shifter setting. I just wished the engine brake would work. Cause I see the light gose on, but the truck going down hill just gose faster and the use of the air brakes do all the stopping. It is like, why even have the light go on.. Guess the dev's felt no one would notice. Apperntly they are right..

-->If your not liking the brakes too much.. Like I stated before, my advice would be for the brakes is move the slider to the right to make it stop like a car.

If it will make you feel better about US trucks and how the game is using brakes, here is a vid I found on a runaway, maybe it will make your day brighter, put a smile on your face... I think two are tests, but the rest are real run aways. In the US Runaway ramps are used for this. Trucks with smoking tires is the result of brake fade, brakes heat up and then fade out. This is why down shifting and the engine brake gets used. Real US trucks just do not do it like European trucks. H-shifter or automatic.

You would not believe this! I can not even believe this. SCS must care about their truck game. Today I decide to go back and my game list shows it is uninstalled, when I can see in the explorer that it is. So I just go install it anyway. And when I start it, it says the game was updated. And to my suprise, the trucks have prefomance and speed when using the H-shifter like they should, and the engine brake is working! I am really impressed. I didn't expect this.... Have to say they did good here...
Oparator Stalker Jul 20, 2018 @ 10:16am 
Oh wow they even restored the low air pressuer alarm! These guys are awsome!
