chrono::vehicle::ChSuspensionTestRigDataDriver Class Reference
Description
Driver inputs for a suspension 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:
time | steering | left_post0 right_post0 | left_post1 right_post1 | ...
It is assumed that the time values are unique. Inputs for post_left, post_right, and steering are assumed to be normalized in the range [-1,1]. Driver inputs at intermediate times are obtained through cubic spline interpolation.
