This section describes how to build events in the full vehicle model with advanced driver. The new event user interface is supported only for models with advanced driver. The interface exports .adf and .xml files and submits them to MotionSolve. Files can be edited or updated in the Event Editor. Sixteen event types are supported.
A Constant radius event simulates a vehicle driving in a circular path.
A Single lane change event drives the vehicle through a single lane change, attempting to follow the centerline of the defined lane.
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.
A Swept Sine event simulates a vehicle driving at a constant speed with a sinusoidal steering input of constant magnitude but increasing frequency applied.
A Straight line acceleration event simulates a vehicle accelerating at a constant rate in a straight line.
A Straight line Braking event simulates a vehicle slowing in a straight line.
A Sinusoidal steering event simulates a vehicle driving at a constant speed while a sin wave input is applied to the steering wheel.
A Braking in a turn event simulates a vehicle decelerating in a circular path.
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.
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.
A Swept steer event simulates a ramped steer input into a vehicle driving at a steady speed.
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.
A Throttle-off turn-in event simulates the dynamics of a vehicle driving a constant radius turn at steady state, the reaction of the vehicle due to a sudden removal of drive torque during the cornering event.
A Step steer event simulates vehicle response to a sudden step input to the steering wheel.
A Power-off in a straight line event simulates the dynamics of a vehicle due to a sudden removal of drive torque.
The Altair Driver File event allows you to run your own Altair Driver File and use this file in the event.
The Road Course event can be used to simulate full vehicle models on the required road profile. The event also provides a means to study vehicle performance in the areas of durability/fatigue and ride comfort.
The n-Post event simulates a vehicle supported on a test-rig by posts.
This section describes the sequence of actions performed by MotionView and MotionSolve when you run the event.
The Altair Driver is a set of MotionView models and libraries that allows MotionView users to control and script vehicle events.
Controllers form the core of the driver. The Controller Library has various basic controllers its arsenal as of now and will be enhanced with many advanced controllers in the near future.
Altair Driver is a simple driver model. This is used in all MotionView and MotionSolve vehicle events. The controller can predict the future road path based on the current vehicle state, has knowledge of the vehicle dynamics, and has access to user-defined driver parameters.
Driver can be loaded using the Task Wizard of MDLLIB. 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.
