Enhanced Altair Driver

For vehicle models following a path using the feedforward steering controller in the Altair Driver overall CPU time is reduced up to 30%. The reduction was realized by optimizing evaluation of the internal bicycle model used by the feedforward steering controller to predict the vehicles path.

The Altair Driver is enhanced to support steering the vehicle from steering gear (e.g. rack-pinion or recirculating ball) without the need for a steering wheel and column. The vehicle parameters input to the driver now include markers on the left and right front wheels to enable the driver to determine the overall steering ratio.

 

Enhanced MDLLIB Steering Systems

The rack and pinion, parallel link, and double idler arm steering systems include new output requests for the rack travel and force, and worm shaft rotation and torque. Further the inner tie rod ball joint is lowered in the parallel link and double idler arm steering systems to reduce roll over steer.

 

Enhanced Bump and Rebound Stop AutoEntities

The bump and rebound stop AutoEntities now allow you to set the diameters of the stop graphics. Previously the diameters depended on the distance between the I and J bodies and could not be set by the user.

 

Enhanced MDLLIB Deformable Strut System

The deformable strut system now includes output requests for the spring and shock absorber displacement, velocity, and force.
