The funny thing is, I think (nearly) all cars, with minor changes to the ABS unit, could have the hardware necessary for brake based torque vectoring within the ABS unit.
But, due to the ABS unit software being contracted out to a different company, it only is used for ABS and cannot act to make the car have a virtual diff lock, unless the car manufacturer wants to pay Bosch the extra $$$ for different software.
- fingerlocks 2y agoIt’s not that simple. “Naive” torque vectoring will shatter CV axles if the drivetrain isn’t designed for it. Consider the scenario when three wheels are completely stuck in mud/sand and one is spinning. If the load is transferred from the free wheel and the others don’t gain traction, something will give.
- londons_explore 2y agoSoftware would presumably be programmed with those limits to not break stuff. During normal operation, every gear in a differential holds the whole drive torque anyway. So really the only issue is sudden changes in wheel vectoring which could end up using engine/driveshaft momentum to smash gears. You'd just program the software to not do that.
