Obtaining Torque Data from the Steering Wheel of a Sedan Vehicle

[Recep KOÇ]

Hello, I want to obtain the steering torque responses that come to the steering wheel depending on different road conditions from a sedan vehicle. How can I do this? I also want to create a steer-by-wire model. How can I model it?

At this time, we do not have a steering mechanism template that includes the steering column.

For all existing steering mechanism templates (see wheeled_vehicle/steering), the steering driver input (in [-1,+1]) is converted in a rotation angle and applied to the driving element of the particular steering mechanism (e.g., the revolute joint connecting the arm to the chassis for a PitmanArm, or the rack displacement for a RackPinion). You can get the corresponding reaction torque, but that will not be at the steering wheel (unless you assume the steering column has no compliance).

 

So, this is effectively steer-by-wire (no steering column). You can implement whatever model you want to produce the steering “driver input” value in [-1,+1].
