Driver-vehicle interaction – ergonomics, forces, fatigue

Industries Automotive Driver-vehicle interaction – ergonomics, forces, fatigue

When the driver is interacting with the vehicle package, the muscle forces arising from the interaction can be evaluated using the AnyBody Modeling System. This allows population studies to be carried out inside or outside the vehicle with the human model interacting with the vehicle elements such as pedals, steering-wheel, handbrake, and doors.

Examples:

  • Ergonomic evaluation of handbrakes
  • Simulation of steering manoeuvres
  • Simulation and optimization of brake feel
  • Simulation of operating brake pedals
  • Quantifying fatigue associated with vehicle operation

Examples of input and output for a model of driver-vehicle interaction

Input:

  • Posture/motion of human model
  • Vehicle CAD model

Output:

  • Muscle and joint reaction forces
  • And much more

The steps to model this can be the following

  1. Start with the motion capture model Multi trial MoCap Model to define the experimental setup
  2. Define the experimental setup by defining the force plates (if any)
  3. Run the motion analysis
  4. Run the inverse dynamic analysis
  5. Evaluate the output

Models in AMMR

  • The SeatedHuman model can conceptually be used as a starting point for the model assuming no motion capture data is being used as input to the model.
  • If motion capture data is being used as input the model, the model can be based on the a mocap model: Multi trial MoCap Model
