chrono::vehicle::ChTrackTestRigRoadDriver Class Reference
Description
Driver inputs for a track test rig based on road profile.
A driver model based on a user-specified road profile. Post displacements are computed based on current road height at each post location and a given translation speed of the road profile. The road profile input data is assumed to contain (x,z) pairs, with x locations in increasing order.
