In career mode the cars will sometimes stop working and I can't drive them in reverse or drive/1st gear, and the parking break is off. I have no idea why this happens but its only fixable when I repair the car.

 

Yes



When there is no pressurized air and the parking brake has been applied, you are unable to release it as pressurized air is required to overcome the tension of the springs that press the brake pads against the brake.

With the air tank of the Cabover truck being fully empty, you are unable to release the handbrake. You can try but it instantly reapplies. See how the P-BRK (handbrake) column flickers in vain when I try to release the handbrake.

Starting the engine of the cabover truck also starts up the air compressor. Because the air tank is fully empty, it requires several seconds for the system to build up enough air pressure to release the parking brake. You can see how the Cabover truck is trying to accelerate but only does so slowly as the engine fights with the applied parking brake. So unlike normally (in the game) the parking brake is not automatically released once the vehicle receives throttle, because it cannot be released due to lack of air pressure.
The running engine however builds up sufficient air pressure after a bit and then the parking brake is finally released, allowing regular acceleration.

I repeat the experiment while looking at the air pressure gauge and again, the truck first fights with the brakes until they are released by building up sufficient air pressure.

Shutting down the engine stops the air compressor and as such no more supply of pressurized air is available. The tank pressure goes down with every brake application (and other air using things). Applying and releasing the brakes causes loss of air until the critical treshold is reached at which times the remaining air pressure is to low to overcome the tension of the springs, the parking brake is locked and cannot be released without building up air pressure again.


Switching to the Conventional Truck with a Trailer attached. Because the trailer has an own air tank, that air pressure equalizes with the trucks air system so even though the truck had no air, it gets enough air from the trailer to release the brakes and drive away normally.

Removing air pressure from the trailer and then resetting the truck, finally leaves the truck and trailer air system with no pressure. Now, with both truck brakes and trailer brakes being fully applied, the truck is unable to move as its engines power is incapable to overcome that braking power. Only when the air pressure reaches a high enough level, the brakes are released, allowing the truck to move. This takes longer as the trucks air compressors needs to fill both the tank of the truck and the tank on the trailer as well as all air lines.


Accelerating the truck and trailer, then evacuating the air from the trailer, causings the brakes of the trailer to engage, forcing the still towing truck down to a very slow speed. Supplying Air to the trailer again disengages the trailer brakes, allowing the truck trailer combination to accelerate normally.


Again accelerating the truck and trailer, then disconnecting the trailer from the truck at speed to simulate an accidental disconnect on the highway. Detecting sinking air pressure due to being disconnected from the truck, the now "autonomous" trailer instantly begins to heavily brake, coming to a quick stop while the now unburdened truck keeps on trucking - at least until it is stopped by a rather unforgiving wall. This behavior is very good in real life as nobody wants an massive 40 tons trailer to go astray and it dropping an anchor instead is much much more favourable to everyone involved. Still, the possibility of an air leak happening is not zero and this is one more reason of keeping your distance behind a truck. You dont want to get intimate with it when its brakes go into full service out of nowhere

Yes, Europa = Europe in german, my mistake

I think that with "AirSpeed" the physical accurate speed of the vehicle in the virtual game world is meant. Assuming there would be no wind, real air speed would be pretty accurate even when wheel speed is not.

I dont assume that adding Wind via the Wind-UI-App would affect it.

Thank you for explaining and offering examples, where speed measuring by other means than wheel speed can actually be worse.

The hamster wheel will see the car having significant wheel speed but obviously it is not really moving much at all. Realistic ABS will just look at wheel speed and as such will have little issues. Meanwhile Arcade ABS will look at "AirSpeed", assume that the vehicle is not moving much (because in terms of changing world coordinates, it isnt) and as such sees no reason to engage ABS.

Very neat.

I believe @Diamondback once explained to me, that the reason for no e-diff on the electric drivetrain for the Vivace is that it tends to put a lot of heat into the brakes when you use it for spirited driving. My own tests using mod added advanced differentials confirmed that. It is especially bad for the Open Diff as this one needs the most E-Diff-Intervention in spirited driving, leading to a substantial additional heat load on the brakes.

I assume it is the peculiarities of the electric drivetrain that makes the brakes suffer so much more compared to an ICE powered vehicle. The instantly available peak torque increases the brake effort required to achieve a given intervention, a fact not helped by a lot of hard cornering happening at speeds where the electric motor are close to their peak power. The instantly availability of electric torque also puts more demand on the system unlike for example on ICE based Vivaces that are turbocharged and when you lift of the throttle and reapply it, it takes a short moment for the engine to regain peak torque. It is only a short difference but it might make a difference that then adds up in sustained hard cornering.

Nuff said, the E-Diff on the Electric Vivace has to fight a lot more average engine torque/power than on an ICE, leading to significant thermal stress on the brakes, brakes that already are stressed by the higher mass of the vehicle that was also meant to brake mostly with the regenerative brakes in the first place.

There is probably a reason, why electric vehicles come with their own
-Traction Control
- ESC
- Drive Modes

The improved regenerative braking logic could possible mitigate the issue to an extent, one would have to test with something else than a keyboard (keyboard is 100 % brake power, leading to regenerative braking shutting down to 50 % strenght the moment brake effort reaches 100 % on the pedal and axles UI-App.

With a finer control on the brake, one might be capable of unloading more regular braking duty onto the regenerative brake even in spirited driving, thus making the added heat of E-Diff a lesser concern.

That sounds like you grinded the gears to me. Be sure to shift not to fast or use Arcade Gearbox.

 

I don't think so, because when I switch to another car, and go back to it, it works again.

 

Hi Everyone!

I am new here and decided to introduce myself to the community and say hi.

I have a question - Are all game mods free or you can buy premium mods ??

Thanks!

 

In the new delivery mission on the Automation map, I failed to fold the trailer (shorten it) for the first time, when I press the gas pedal, the parking brakes automatically turn off , I know that it can be turned off in the settings, but I can't find where. Secondly, the blue button on the trailer does not fix it in the short position.

 

Repository mods are free, forum ones can be paid if the developer chooses to do so.

 

Wait, you’re back? Sweet.

 

Yeah. Still not entirely fixed as I have to get permission to post in the update speculation thread.

 

Found two more wrong details with the remade T-Series.

1) Unlike the Cab-over Aero Cab, the Conventional Large Aero Cab has no Sleeper Window Covers in its "Interior" slot of the parts selector.
2) The Interior Color of the Cab-overs should be in the "Interior" slot, like the Conventionals have it. It's slightly counterintuitive trying to find the colour in the "Interior" slot without imagining it being in the "Cab" one it now is.

 

At least you have the account back.

 

Yep!

 

I manage to finish less than 2:40 mins but it doesn't count me the last star in this mission.
It's the crawling mission in Automation.

 

Arcade ABS is triggered when a vehicle brakes while on a moving vehicle

 

yes because it works off of air speed.

 

Some minor details I found:

• The T-Series "TC83s Upfit Frame" states it is for upfit configurations, despite the "Medium Upfit Frame" / "Medium Straight Frame End" configuration being the only one not supporting upfits.
• The "TC83 Upfit Frame" description has one 'for' too many
• Fuel tanks on the "Gambler 500 - The Incapable" Covet are using misplaced meshes. jbeam looks like this
  
  Code:

  "covet_boxutility_fueltank_R": {
      "flexbodies": [
          ["mesh", "[group]:", "nonFlexMaterials"],
          ["pigeon_fueltank", ["boxutility"],[],{"pos":{"x":0.407, "y":0.974, "z":0.167}, "rot":{"x":0, "y":0, "z":90}, "scale":{"x":1, "y":1, "z":1}}],
  },
  "covet_boxutility_fueltank_L": {
      "flexbodies": [
          ["mesh", "[group]:", "nonFlexMaterials"],
          ["pigeon_fueltank", ["boxutility"],[],{"pos":{"x":0.407, "y":0.974, "z":0.167}, "rot":{"x":0, "y":0, "z":90}, "scale":{"x":1, "y":1, "z":1}}],
          ["pigeon_fueltank", ["boxutility"],[],{"pos":{"x":-0.206, "y":0.974, "z":0.167}, "rot":{"x":0, "y":0, "z":90}, "scale":{"x":1, "y":1, "z":1}}],
  }

  Right one should have "x":-0.206, left one "x":0.407 and only one mesh
  

 

Whenever the T-Series is connected to a trailer, and you press reset, the trailer resets with it, and connects automatically to the T-Series. But when it does this with a tanker trailer connected, the bottom of the tanker trailer glitches into the fifth wheel, which causes problems sometimes (mostly when maneuvering the truck).

 

When will the faulty 'engine off' notifications be fixed?

 

Additional Modification slot is also missing for some reason.

 

Hey
I found a missing part on the city bus, the Ram Plow. (checked in safe mode)

I noticed that in the citybus_ramplow.beam file the name of the mesh is "ramplow_low" and didn't find it in the files.



I searched for it and found the mesh file in the common folder, and changed it to ramplow, and it now shows properly


Also, on the us_semi I found it a bit low and it cuts through the ground, so I changed the z-axis to 0.885 and I think it looks better.



*You can use the front lifted springs on the semi instead
Hope it helps, Thanks for your amazing work!
