Self Study Program 374 – Traction Control and Assist Systems

VAG SSP 374. This fundamental information booklet provides an overview of these systems. In addition, their fundamental functional principles and which components work together in the relevant systems are explained.

Increasing speed and road traffic density are increasing the need for vehicle dynamics which offer the highest possible level of safety under all operating conditions. This is being achieved via a rising number of traction control and assist systems, some of which have been derived from the anti-lock brake system (ABS) and which support the driver.
