ADAS Application: Automatic Emergency Braking

Active Safety, Advanced Driver Assistance Systems (ADAS) are now being introduced to the marketplace as they serve as key enablers for anticipated autonomous driving systems. Automatic Emergency Braking (AEB) is one ADAS application which is either in the marketplace presently or under development as nearly all automakers have pledged to offer this technology by the year 2022. This one-day course is designed to provide an overview of the typical ADAS AEB system from multiple perspectives. A technical overview of the development cycle processes specific to AEB, including system level requirements and design architecture will be presented as well as design considerations for AEB from a functional safety (ISO‐26262) perspective. A general overview of algorithm concepts for the various AEB subsystems will be demonstrated followed by a review of AEB system test and validation methods. Finally, discussion is facilitated toward understanding customer perception and acceptance of AEB at present. The participant should obtain a fundamental understanding of design principles and functional composition for a typical AEB system.

What Will You Learn

By attending this seminar, you will be able to:
  • Describe AEB features / functionality as provided by most OEMs, including the capabilities and limitations of typical AEB systems
  • Identify key principles of vehicle dynamics and system engineering disciplines which are integral to AEB system development
  • Describe the general activities required for driving and braking tasks and comment on how these form the bases for AEB system requirements
  • Identify AEB system architectures and subsystem composition and describe the function and purpose of each subcomponent
  • Identify functional safety (ISO 26262) implications specific to AEB including review of basic hazard and risk analysis examples
  • Explain algorithm concepts and functions for each of the AEB subsystems
  • Critically examine various methods and levels of testing specific to AEB
  • Describe the current state of AEB development from a consumer perspective
