Description

Base class for a suspension test rig driver system.

A driver system must be able to report the current values of the inputs (left posts, right posts, steering). A concrete driver class must set the member variables m_displacementLeft, m_displacementRight, m_steering, and - if possible - the rates of change for the displacements (otherwise left at their default value of 0).

◆ Started()

bool chrono::vehicle::ChDriverSTR::Started ( ) const

Return false while driver inputs are ignored (while the rig is reaching the ride height configuration) and true otherwise.

In general, outputs from the test rig should only be collected while Started returns true.
