Correct Traction Control Logic

As of 0.18, the traction control compare diagonal opposed wheel, i.e FL to RR and FR to RL wheels, which is incorrect because the TCS will not work when both of the diagonal wheels lose traction that is quite common in both front and rear open differential vehicles such as the eSBR.

look into the "D:\Program Files (x86)\Steam\steamapps\common\BeamNG.drive\lua\vehicle\controller\esc.lua", note these in line 997 to line 1000

Code:

 --TCS
  crossWheels[frontLeftWheelId] = rearRightWheelId
  crossWheels[rearRightWheelId] = frontLeftWheelId
  crossWheels[frontRightWheelId] = rearLeftWheelId
  crossWheels[rearLeftWheelId] = frontRightWheelId

To solve the problem, edit them to

Code:

--TCS
  crossWheels[frontLeftWheelId] = frontRightWheelId
  crossWheels[frontRightWheelId] = frontLeftWheelId
  crossWheels[rearRightWheelId] = rearLeftWheelId
  crossWheels[rearLeftWheelId] = rearRightWheelId

Then the problem solved
The Hirochi Sunburst Sport S AWD has a viscous tansfercase that is FWD unless wheelspin, and both the front and the rear differentials are open diffs. It can now pass AWD test that only one rear wheel has grip.

 

Thanks for your reply, I understand this. It should use both of the logics.
Speed difference between FL-RR or FR-RL wheels are too large → reduce throttle
Speed difference between FL-FR or RR-RL wheels are too large → brake the faster wheel.
