The abilities of ABS can be used during normal driving, but it does not affect handling in emergency situations. In the design of an ABS system, you need to understand the properties of the tire-road interaction first. Improved braking efficiency would be obtained if the tire's slip can be kept constant regardless of which brake is used. The design aim of ABS is to help improve vehicle traction by limiting wheel lock during braking, but to keep vehicle steer ability and vehicle wheels in balance. Although full traction is required for straight-line driving, a balance between stability and braking can be necessary when turning. Even those vehicles fitted with traditional anti-lock brakes could go out of control if subjected to this form of control. Recent advancements include the application of wireless accelerometers, dynamic tire and suspension models, and adaptive control to the parameters such as acceleration and lateral slip. More recently, four-wheel steering and active suspension have been built into vehicle systems such as four-wheel drive. Future updates could include sensors made out of smart materials, as well as vehicle-to-to-vehicle communications.
