  - 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.
      - Constant Radius
        A Constant radius event simulates a vehicle driving in a circular path, typically with increasing speed. The event predicts the vehicles roll and understeer characteristics with increasing lateral acceleration.
      - Single Lane Change
        A Single lane change event drives the vehicle through a single lane change, attempting to follow the centerline of the defined lane.
      - Double Lane Change
        A Double lane change event drives the vehicle through a lane change and a return to lane maneuver, attempting to follow the centerline of the defined lane.
      - Swept Sine
        A Swept Sine event simulates a vehicle driving at a constant speed with a sinusoidal steering input of constant magnitude but increasing frequency applied.
      - Straight Line Acceleration
        A Straight line acceleration event simulates a vehicle accelerating at a constant rate in a straight line.
      - Straight Line Braking
        A Straight line Braking event simulates a vehicle slowing in a straight line.
      - Sinusoidal Steering
        A Sinusoidal steering event simulates a vehicle driving at a constant speed while a sin wave input is applied to the steering wheel.
      - Braking In a Turn
        A Braking in a turn event simulates a vehicle decelerating in a circular path.
      - J-turn
        A J-turn event simulates a vehicle response to a large steer in one direction, a dwell time to allow the vehicle to react, and a large steer in the opposite direction, with an additional reaction time.
      - Throttle-off Cornering
        A Throttle-off cornering event simulates the dynamics of a vehicle driving a constant radius turn at steady state and the reaction of the vehicle due to a sudden removal of the drive torque while cornering.
      - Swept Steer
        A Swept steer event simulates a ramped steer input into a vehicle driving at a steady speed.
      - Pulse Steer
        A Pulse steer event simulates a vehicle response to a sudden pulse input to the steering wheel while driving in a straight line at a constant speed.
      - Throttle-off Turn-in
        A Throttle-off turn-in event simulates a vehicle driving straight at constant speed, turning on to a constant radius, then after reaching steady state the throttle is closed and the steering is ramped to tighten the turn.
      - Step Steer
        A Step steer event simulates vehicle response to a sudden step input to the steering wheel.
      - Power-off in a Straight Line
        A Power-off in a straight line event simulates the dynamics of a vehicle due to a sudden removal of drive torque.
