TRW’s Anti-lock Braking Systems (ABS) assist drivers in maintaining vehicle control and avoiding wheel lock during emergency stop situations or on slippery surfaces.

ABS uses four independent sensors that individually monitor each wheel's speed. When wheel lock or skidding is sensed, a signal is sent to the ABS Electro-Hydraulic Control Unit (EHCU), which controls the system and can determine when a panic situation exists. If the equipped vehicle goes into a panic situation, TRW's ABS system initiates, activating the hydraulic units that apply and release brake pressure very rapidly to prevent wheel lock. In the case of four-wheel ABS, all four wheels continue to rotate, allowing a driver to steer away from objects during rapid deceleration.

TRW’s Anti-lock Braking Systems have evolved to offer additional functionality, such as dynamic rear proportioning that provides enhanced balance and handling performance.
