Introduction to Brake Control Systems: ABS, TCS, and ESC PD730501

Once reserved for high-end luxury vehicles, electronic brake control systems are now required 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 course introduces participants to the system-level design considerations, vehicle interface requirements, and inevitable performance compromises that must be addressed when implementing these technologies.

The course 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, 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 heavy emphasis placed on the resulting vehicle dynamics. The course concludes with a study of unique applications, a look forward to advanced brake control system integration, and an overview of Federal Motor Vehicle Safety Standard 126.

While the course is approximately ten hours in length, the estimated time to completion, including knowledge checks and the learning assessment is 11 hours.

Objectives

By participating in this on-demand course, you'll be able to:

  • Analyze brake system design parameters and their vehicle performance effects
  • Evaluate the compromises between stability, steerability, and stopping distance
  • Identify the discrete mechanical components required for ABS
  • Specify fundamental ABS performance attributes
  • Calculate dynamic brake balance and explain the benefits of DRP
  • Reconcile TCS performance expectations vs. method of implementation
  • Define ESC performance metrics and physical limitations
  • Assess features such as adaptive cruise control and brake assist
  • Interpret federal requirements for the performance of ESC

Materials Provided

  • 90 days of online single-user access (from date of purchase)  to the ten hour presentation
  • Online learning assessment (submit to SAE)
  • Course handbook (downloadable, .pdf's)
  • Instructor follow up to your content questions

Is this On Demand Course for You?

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.

This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 10 Continuing Education Units (CEUs). Upon completion of this seminar, accredited reconstructionists should mail a copy of their course certificate and the $5 student CEU fee to ACTAR, PO Box 1493, North Platte, NE 69103.

This course is equivalent to the classroom seminar, Introduction to Brake Control Systems: ABS, TCS, and ESC, and satisfies a requirement in both the Vehicle Dynamics and Accident Reconstruction Certificate Programs.
