Will the original traction control still work on a fwd ev conversion? I am worried about wheel spin in hard accelerations.
Yes, sort of. They're wheel speed sensors, not wheel position sensors. An individual slipping wheel is managed by brake application, and almost no conversion retains the powertrain donor's brake system to make that possible. If both driven wheels are slipping, and to some extent even if only one is, the motor power is reduced, and that should still work (assuming that the wheel speed sensors are retained).As I understand, traction control is handled by some ECU, sensored by wheel position sensors, mechanically actuated by selectively applying specific brakes. ... steering may also play if it's going to be picky. If that's correct (at all, or, for the flavor of traction control you have)...
It's definitely possible that it will still work in a conversion. It has the ability to work. The wheels can still give sensor data, the brakes can still be applied, the ECU still exists.
True - anything with a limited-slip diff should definitely have traction control to avoid this. Of course this isn't an issue in production cars, since everything new has traction control now.Even with RWD an LSD is problematic
With an open diff one tyre spins and the other does not "drive" the car --- BUT the non spinning tyre still provides sideways grip so the car does not accelerate but it does go around the corner
With an LSD if both tyres spin then you lose sideways grip as well and the cornering forces are no longer resisted so the car spins
No the original (electronic )traction control will not. You are still reading the the input from the sensors and feeding it to the ECU (assuming you keep it) but the old ECU is not communicating with your new EV-KIT unless you have bought a special conversion designed for the version of car you are converting. You could use the existing sensors to feed data into your EV-kit but be aware that these are sensors designed for ICE not an EV.Will the original traction control still work on a fwd ev conversion?
