>>1854813>>1859573No. the problem is that the tilting was too slow to react because it corrected for lateral force.
This meant that in a corner, the APT passenger feels lateral force - the apt tilts and negates the force - the force disappears and the APT stays tilted - the APT straightens up. So every corner the passenger is being thrown sideways in multiple directions, which is uncomfortable at best and disorientating at worst.
The italian pendulaire was the first system of this type to fix the issue, and it did it by correcting for yaw (i.e the angle between the bogies) instead of lateral force.
This way it's able to actually start leaning before the lateral force starts setting in, and thus can afford to make smoother adjustments to further accommodate irregular corner radius.
