Testing Human Machine Interface (HMI) Rich Designs Using Model-Based Design

By Chris Fillyaw, Jonathan Friedman, and Sameer M. Prabhu, MathWorks


Most vehicles today are outfitted with passenger convenience features that require human - machine interfaces (HMIs). An HMI can be relatively simple, such as a remote key fob, or more sophisticated, such as a radio face plate. As the complexity of the system increases, so does the need for intuitive and easy-to-use HMIs. For teams that use traditional methods to design, prototype, and test an HMI, achieving this level of ease of use is becoming increasingly challenging.

This paper addresses two important workflow issues to support the design and verification of HMI logic: integration of the HMI graphics and logic, and formal verification of the logic using a virtual HMI connected to a Simulink® model.
