chrono::vehicle::ChTrackTestRigDataDriver Class Reference
Description
Driver inputs for a track test rig from data file.
A driver model based on user inputs provided as time series. If provided as a text file, each line in the file must contain the following values:
time displ_post1 displ_post_2 ... throttle
It is assumed that the time values are unique. If the time values are not sorted, this must be specified at construction. Inputs for post displacements and throttle are assumed to be in [-1, 1]. Driver inputs at intermediate times are obtained through linear interpolation.
