Offered through SAE International

I.D.# C0315, Duration: 2 Days

Once reserved for high-end luxury vehicles, electronic brake control systems are quickly becoming standard equipment on even the most inexpensive cars and trucks. Today, nearly every new vehicle benefits from the optimized braking, enhanced acceleration, or improved stability that these systems provide. This comprehensive seminar introduces participants to the system-level design considerations, vehicle interface requirements, and inevitable performance compromises that must be addressed when implementing these technologies.

This course is also available in a self-study e-Seminar!

The seminar begins by defining the tire-road interface and analyzing fundamental vehicle dynamics. Following an in-depth study of system electronics, hydraulic hardware, and sensor requirements, the participants learn about the control strategies employed by anti-lock brakes (ABS), dynamic rear proportioning (DRP), traction control (TCS), and electronic stability control (ESC) with strong emphasis placed on vehicle dynamic response. The seminar concludes with a study of unique applications, industry trends, and a look forward to advanced brake control system integration. Over 500 pages of detailed course notes and illustrations are provided for on-the-job reference.

This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 13 Continuing Education Units (CEUs). Upon completion of this seminar, accredited reconstructionists should contact ACTAR, 800-809-3818, to request CEUs. As an ACTAR approved course, the fee for CEUs is reduced.

Learning Objectives
By attending this seminar, you will be able to:

  • Analyze brake system design parameters and their vehicle performance effects
  • Evaluate the compromises between stability, steerability, and stopping distance
  • Discern the discrete mechanical components required for ABS
  • Specify fundamental ABS performance attributes
  • Estimate dynamic brake balance and explain the benefits of DRP
  • Reconcile TCS performance expectations vs. method of implementation
  • Interpret ESC metrics and ultimate dynamic limitations
  • Discuss opportunities for advanced brake control system integration

Who Should Attend
This course has been developed for engineers involved in all fields related to the design or development of vehicle dynamics, vehicle braking systems, powertrain systems, chassis systems, or suspension systems. In addition, this course can be valuable to those with component design responsibilities in brake, chassis, suspension, or tire disciplines.

Individuals new to the field of brake control systems will benefit most from the material; this introductory course is not intended for individuals with significant experience with brake control systems. In addition, please note that because of proprietary considerations this class does not provide details of algorithm design, algorithm performance, or algorithm application. Instead, the course places strong emphasis on vehicle dynamic responses.

Prerequisites
An undergraduate engineering degree or a strong technical background is highly recommended. A basic knowledge of college algebra, college physics, and a familiarity with vehicle brake and suspension systems is required.
