Recent trends in automotive engineering, such as electrification and
automatization, are opening chances as well as challenges due to the increased
demand on new chassis components (e.g., drivetrain, brakes, steering,
suspension, etc.) and control methods. This fast-growing market requires new
methods to frontload as much efforts as possible to early design stages. The
present article deals with a relevant case study on anti-lock braking system
(ABS) design and tuning via hardware-in-the-loop (HIL) tests and rapid control
prototyping (RCP) techniques on a hybrid brake-by-wire (BBW) system. Three types
of wheel slip control algorithms are tested and benchmarked against each other.
It was demonstrated that HIL simulations are suitable to develop vehicle
subsystems and control strategies in a quite realistic manner even if the target
vehicle or prototype is not available yet. Moreover, the benefits of continuous
control approaches against classical rule-based wheel slip control were shown.
In the article, aspects such as brake system architecture, control design, HIL
testing environment, validation studies, and their analysis are further being
discussed.
