Hotel & Travel Information

Experience the vehicle dynamic enhancements afforded by anti-lock brakes (ABS), traction control (TCS), and electronic stability control (ESC) with this highly interactive two-day seminar. Designed to get you out of the classroom and on to the test track, a total of six 60-minute structured learning experiences behind the wheel will vividly illustrate the benefits, limitations, and ultimate compromises that must be made when designing and implementing modern brake control systems.

In order to provide a solid foundation for the in-vehicle learning experiences, each driving session is preceded by a 60-minute classroom presentation focusing on one key element of ABS, TCS, or ESC. Six of these class/track modules are then linked together in continuous fashion to provide the fundamental knowledge required to specify, design, and evaluate these technologies.

Vehicles used for demonstration will be capable of allowing attendees to directly compare their best-unassisted driving performance to the enhanced vehicle dynamics provided with the systems fully enabled. The seminar concludes with a brief exposure to the complex interactions between these technologies on a specially-prepared low-coefficient handling course. Detailed course notes and illustrations are provided for on-the-job reference. In order to cover all content and provide effective driving exercises, this course requires eight hours of instructional contact per day versus SAE's normal 6.5 per day.

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

  • Define the trade-offs between ABS stability, ABS steerability, and vehicle stopping distance
  • Analyze the compromises made during ABS transitions and split-coefficient deceleration
  • Explain the benefits and limitations of engine-only TCS, brake-only TCS, and full-function TCS
  • Evaluate the effectiveness of engine-only TCS, brake-only TCS, and full-function TCS
  • Interpret ESC metrics and assess overall system performance
  • Experience moding interactions between ABS, TCS, and ESC

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. Due to the in-depth discussion of real-world system limitations and compromises, it may also be of interest to those in accident reconstruction and product litigation. 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 course is not intended for individuals with significant pre-existing experience in 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 to typical brake control interventions.

Prerequisites

***Please be advised that this course involves one or more of the following: driving and/or riding in a vehicle; participating in a vehicle demonstration; and/or taking part in an offsite tour using outside transportation. You will be required to sign a waiver on-site and produce a valid driver’s license from your state/country of residence.***
