ABS With Traction Control and Interactive Vehicle Dynamics (IVD)

WARNING: This page is about a different car, the 2009 Mercury Sable, 2009 Ford Taurus X, and 2009 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.

The ABS with traction control and interactive vehicle dynamics (IVD) consists of the following components:

ABS module
Front wheel speed sensors
Front wheel speed sensor rings (integral to the front wheel bearing)
Hydraulic control unit (HCU)
Rear wheel speed sensors
Rear wheel speed sensor rings (integral to the rear wheel bearing)
Stability control sensor cluster
Steering wheel rotation sensor
Stability/traction control switch

The ABS prevents wheel lock-up by monitoring the wheel speed sensors and actuating the valves in the HCU, which modulates the brake pressure to the brake calipers. By preventing the wheels from locking up, the driver is able to maintain steering control and stop in the shortest possible distance under most conditions. The traction control system utilizes the same components as the ABS to prevent wheel spin and help maintain vehicle control during acceleration. The IVD system utilizes the same components as the ABS and the traction control systems and also monitors the steering wheel position sensor and the stability control sensor cluster to assist in stabilizing the vehicle during abrupt maneuvers.

The front wheel speed sensor rings are integral to the front hub and bearing assemblies. Refer to FRONT SUSPENSION article.

The rear wheel speed sensor rings are integral to the rear hub and bearing assemblies. Refer to REAR SUSPENSION article.
