chrono::vehicle::ChTrackTestRigInteractiveDriver Class Reference

Description

Interactive driver for a track test rig.

This class implements support for keyboard control of a track test rig, but is independent of a particular implementation of a keyboard event handler.

Member Function Documentation

SetDisplacementDelta()

void chrono::vehicle::ChTrackTestRigInteractiveDriver::SetDisplacementDelta ( double  delta )

inline

Set the time response for post displacement control.

This value represents the time (in seconds) for changing the displacement input from 0 to 1 (or 0 to -1). Default: 1/250.

SetThrottleDelta()

void chrono::vehicle::ChTrackTestRigInteractiveDriver::SetThrottleDelta ( double  delta )

inline

Set the time response for throttle control.

This value represents the time (in seconds) for changing the throttle input from 0 to 1. Default: 1/50.
