  - 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.
      - Open Loop Controllers
        Open-loop controllers define vehicle inputs directly without feedback (for example, steering wheel angle vs. time).
      - Closed Loop Controllers
        Closed-loop controllers use vehicle responses (for example, speed, position, yaw rate, etc.) as feedback to determine the vehicle inputs needed to match a desired vehicle response, such as following a demand lean profile (for two wheelers) or a path.
        
        Throttle and Brake Controllers
        
        Feed-forward Traction Controller
        The Feed-forward controller is the predictive controller of the Altair Driver. It predicts some of the states of the vehicle after look ahead time, or look ahead distance, and accordingly drives the throttle and brake signals to match the demand signal (for example, speed).
        
        Feedback Traction Controller - PID Controller
        A Proportional-Integral-Derivative (PID) controller is a feedback controller that computes a vehicle input using the error, the integral of error, and the rate of change of error between a desired vehicle response and the actual vehicle response.

    - 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.
