Auto Solutions Known Issues

Road Tools:

•The road tools dialog should offer a means to abort road graphics generation because of the large time require for some road file.

Driver:

•Feedforward Controller doesn't follow acceleration profiles well        
•When using the driver, the tire longitudinal slip shows oscillations at time=0
•Zero vehicle speed causes steering controller to fail.
•Driver event UI is experimental:  To enable the event editor button on the driver panel in MotionView set the environment variable HW_MV_EXPERIMENTAL to ADVANCED_DRIVER.

MDLLIB

•Full vehicle events with a powertrain often fail to solve because the suspension spring preloads are too small causing the excessive suspension jounce. We recommend increasing the spring preloads to compensate for the mass of the powertrain, and as always you should update models.
•Steering systems contain dummy bodies to support analyses, but these have no meaning to users.
•Some combinations of wizard selections do not build because referenced system definitions use the same varname.
•To reduce the length of the Constant Radius event the length of the initial straight section should be based on the initial vehicle velocity
