Paired with some Blizzacks it’s good shizzzzzz
Does anyone know what happened to the Traction Control system revamp that Reiza mentioned in the June dev update?:
"On the Physics side, the biggest incoming development is the completion of the Traction Control system revamp that we´ve been working on through this cycle"
I haven't heard about it since. Was it released? is it still being worked on?
I'm referring to many open-diff AWD systems that use ABS to prevent 1 wheel from spinning too much, which "transfers" power to the wheel on the other side. But, it only transfers a small amount of power, because the ABS system seems to "pulse" the wheel that is completely lifted off the ground or on ice, instead of locking completely, causing power to be "lost".
Wouldn't it be a lot more effective if you could completely lock the wheel when it is off the ground or has very little traction? Why don't brake based traction control systems offer this as an option? Maybe as button? I don't think Subaru X-Mode does this (though I don't own such a vehicle).
I suppose I could add as related question, why do such systems put heat into the transmission? Is it because of the spinning (which could be prevented to begin with with my proposed implementation?)
These lights came on the other day, my car is still driving well and I have not noticed any performance change. I used an OBD scanner and came up with the code PO57C. A few forums I have been reading it could be the brake pedal sensor, I just wanted to hop on here and get advice on whether it could be that or something else. If anyone had any experience with this code I would love some input!
My Ford ranger T7 model the TCS keeps coming on randomly, even when I'm not driving
What can be the issue ?
MK5 GTI DSG - Please educate me, I came from a world of commuter cars. 10% of the time with everything in normal mode, I often give it 80% throttle out of a turn or just coming out of a turn from a stop (1st or 2nd gear pull). Traction light comes on and cuts throttle for .5 or 1 second from both wheels. Is this ASR or ECS or whatever cutting throttle instead of wheel spinning? Is this normal? Thanks.
They keep saying it's the pinnacle of motorsport but technology that was in the 1993 cars can't be used today.
If such an artificial gimmick like DRS is there, which I hate...I don't see why not.
Wouldn't these be good for the spectacle?
This post is beneficial if you have an interest in racing.
From a driver perspective, completing a task by a due date is akin to racing. Everyone has the same goal and is on the same circuit but not everyone's car drives the same. The deadline has been set with understanding of what to do and that's it. Lights out and away we go! You're watching driver 21 here. Everyone accelerates but oh no, driver 21 is watching everyone else start off with a great launch but they've lost a lot of time with wheel spin. Number 21 lets off the gas, allows the rubber to get some grip and there's still a chance to catch up.
21 is gaining a little on the pack but there's a sharp corner, everyone brakes but their strong ABS is 21's advantage! Number 21 is able catch up the pack in the braking, 21 tries to gas it out of the corner to leave everyone behind but ends up losing control and spinning out. The pack is now off with a slow exit speed because their TCS kept them from losing grip at the cost of speed but they're ahead even still. 21 can accelerate quicker than them once 21 gets traction. Looks like 21's plan is gaining on them in the straight and fast turns. A fast corner appears and everyone is slowing down even though they're planted but 21 is now catching up and overtaking the back of the pack. It's not so hard to get the leaders at this rate but there's a medium speed turn. Driver 21 press on the brakes but locks up the fronts and has too much understeer causing number 21 to have a very wide line, veering off the track. Everyone is perplexed because no other car is doing this so they think 21 is mucking about. Still not in control, the car continues to go it's own way off the track until the tires catch grip again. Number 21 lost some time and is back at the rear again. A fast corner comes by and again 21 is able to overtake but there's also some dampness on the track on the upcoming turn. The rest of the grid drive over it, little slower than usual but no real change in racing line or commitment. Driver 21 approaches the turn as everyone else but the wheels have lost all grip, this is terrible! Number 21 is flooring it hoping it will go faster but they are actually loosing more control and is now battling with the car for stability. While 21 struggled for control, the back of the pack has now caught up and it's near the end of the race. Number 21 had it's moments at the front but lost too much time from being out of control which allowed the rest of the grid to t

I have an 03CVPI that definitely does not have traction control.
I have an 04CVLX on its way that does. But, it's totalled. What components of it are necessary for the traction control to work? Does it have reluctor/tone wheels on each rear wheel where my 03PI does not? Is it something different on the throttle body?
I just need to know, if I want to preserve the traction control feature in the eventual fusion car I build from these two, what components are important to carry over from the LX, besides the traction control button on the dash?
With the recent confirmation of a split power mode (the oft-requested "Snow Mode") I set out to benchmark the traction control performance and regeneration curve of my car under slippery conditions. Where I live has recently experienced a freezing rain followed by 10+ cm of snowfall and a cold snap in the -20°C range, leading to some of the most slippery driving conditions imaginable short of driving on actual ice. I tested my car last night at -13°C ambient on a particular side road that hasn't seen much sanding or grading, leading to a mostly hard-packed snow surface with occasional bare ice exposed. Even though I have nice Nokian Hakkapeliitta R3 winter tires on my car, accelerating at full power under these conditions is definitely a handful, requiring adept corrective steering just to remain pointing straight.
As a baseline measurement, here's a plot of my 2018 Model 3 AWD w/Acceleration Boost under ideal dry roads & warm battery conditions. All my data is captured from the car's CAN bus using Scan My Tesla and is generally sampled at 100 Hz and accurate to 0.01 seconds or better except for wheel RPM counters which update at approximately 10 Hz (every 0.1 seconds). My car will reach 60 km/h 2.52 seconds after the accelerator is first pressed, 60 mph after 4.09 seconds and 100 km/h after 4.27 seconds. Owing to the car's speedometer being tied to some combination of the smoothed data from the position sensors within the motors, there's about a 0.28 second delay between the first recorded change in accelerator pedal position and the first recorded increase in speed. This delay would be somewhat akin to true reaction time and would not normally be measurable or incorporated in a drag strip time or dragy run.
Testing my car in the standard Sport setting and Normal regen produced the following plot. Under the slippery road conditions, 60 km/h was achieved in 6.80 seconds, and 100 km/h was not safely possible. I allowed my car to reach a peak of about 77 km/h as indicated on the speedometer, then completely let off the accelerator pedal and let the car use only regen braking to come to a stop. Aside from an occasional patch of ice and t
... keep reading on reddit ➡Apparently these systems love to fail when power is low. But that is definitely not the case in this scenario. Someone did a little impact to my Odyssey (no visible damage). Any ideas? Anyone with similar experiences? Edit: Problem fixed itself.
I’ve tried playing with Medium and and Off traction control and I’ve learnt the technique coming out from a corner but the high speed turns just feels too scary because I’m scared if I use the throttle too hard I’ll be spinning, also sometimes hitting the apex makes me spin it’s so frustrating. Any tips?
