- Full Vehicle Events and Altair Driver
  - Full Vehicle with Driver
    This section describes how to build events in the full vehicle model with Altair Driver. The new event user interface is supported only for models with Altair Driver. The interface exports .adf and .xml files and submits them to MotionSolve. Files can be edited or updated in the Event Editor. Eighteen event types are supported.
  - Event Types
    This section describes all of the full vehicle events currently supported with Altair Driver. It also describes all of the events and their parameters.
  - Driver Overview
    The Altair Driver is a set of MotionView models and libraries that allows MotionView users to control and script vehicle events.
  - Controllers Library
    Controllers form the core of the driver. The Controller Library has various basic controllers its arsenal to calculate different driver outputs.
  - Additional Altair Driver File Blocks
  - Altair Driver Mathematical Methods
  - Troubleshooting Driver Modeling
  - MotionView Interface
    Driver can be loaded using the Model Wizard of MDLLIB when the Full Vehicle with Driver option is chosen. Driver has some special requirements to interface with the vehicle model. These requirements are resolved automatically if the vehicle model is built using the Full vehicle with advanced driver option in the Model Wizard in MDLLIB.
  - Altair Driver File
    Driver uses the Altair Driver File (ADF) to access all the event parameters in the Solver.
    - TeimOrbit Format
    - Altair Driver File Blocks
    - Open Loop Controllers
      Open-loop controllers define vehicle inputs directly without feedback (for example, steering wheel angle vs. time).
