Ackermann at 50mm Rack Travel – Suspension KPI

Ackermann in a suspension system determines how much the the inside and outside wheels steer during cornering.  As a vehicle corners, the inside and outside wheels travel along different paths.  Ackermann is reported as a percentage, 0% being parallel steer (i.e. inside and outside wheels steer to the same toe angles) and 100% being perfect Ackermann steering.

In RACE, Ackermann is reported at 50mm rack travel.  The steering lock angles at 50mm rack travel are also reported.  It is worth noting that the level of Ackerman in a suspension system changes with steering lock angle.  This can be seen in the curves produced as part of the RACE pdf report.
