Anti-lock Braking System
When NHTSA regulations requiring trailer anit-locking braking systems (ABS) went into effect in 1998, Haldex had already been producing trailer ABS for over 25 years. Today, ABS and Electronic Brake System (EBS) equipped trailers haul freight all over the world, providing controlled safe stopping.
Haldex has an expanded line of Anti-Lock Braking Systems that includes both ABS Relay Valve and the Haldex exclusive Full Funcitnoing ABS (FFABS). Whether you need a 2S/1M single channel or 4S/2M multi-channel, the Haldex ABS product offering has the right system for any trailer configuration.
Haldex's ABS uses PLC Select® technology which provides exclusive control logic for better control and stopping power at every wheel, without the costly second connector. All Haldex PLC Select systems contain the exclusive Select Low/High (SLH) protocol to further enhance sensitivity and responsiveness by cycling deeper and recover faster for more responsive and precise braking control eliminating the need for costlier 2S/2M systems.
Haldex’s newest technology advancement, Intelligent Trailer Control Modul (ITCM) expands beyond the PLC Select protocol to include Controller Area Network (CAN) bus. The CAN communication protocol effectively passes information between CAN equipped devices expanding the functionality of the ABS platform.
