For most vehicles, the max steering angle, left and right, would be the same (as the vehicle has the same turning radius,
left and right). For those vehicles, the value for parameters P3426 and P3428 will be the same. But some vehicles have
different turning radii left versus right, hence the exercise of steering into the smallest circle possible must be done to
both left and right, for obtaining the two Ī-angles.
For an articulated vehicle, the maximum steer angle (left and right) is the maximum steer angle from the joint-sensor,
given in degrees, each with reference to straight ahead. If two sets of joint angle sensors are mounted, then use the values
from the primary joint angle sensor.
Important
For articulated model, if steering sensor is placed in steering cylinder, only consider the angle in the articulation point!
