IntroductionBendix® EC-60™ controllers are members of a family of electronic Antilock Braking System (ABS) devices designed to help improve the braking characteristics of air braked vehicles - including heavy and medium duty buses, trucks, and tractors. ABS controllers are also known as Electronic Control Units (ECUs). Bendix ABS uses wheel speed sensors, ABS modulator valves, and an ECU to control either four or six wheels of a vehicle. By monitoring individual wheel turning motion during braking, and adjusting or pulsing the brake pressure at each wheel, the EC-60™ controller is able to optimize slip between the tire and the road surface. When excessive wheel slip, or wheel lock-up, is detected, the EC-60™ controller will activate the Pressure Modulator Valves to simulate a driver pumping the brakes. However, the EC-60™ controller is able to pump the brakes on individual wheels (or pairs of wheels), independently, and with greater speed and accuracy than a driver. In addition to the ABS function, premium models of the EC-60™ controller provide an Automatic Traction Control (ATC) feature. Bendix ATC can improve vehicle traction during acceleration, and lateral stability while driving through curves. ATC utilizes Engine Torque Limiting (ETL) where the ECU communicates with the engine’s controller and/or Differential Braking (DB) where individual wheel brake applications are used to improve vehicle traction. Premium EC-60™ controllers have a drag torque control feature which reduces driven-axle wheel slip (due to driveline inertia) bycommunicating with the engine’s controller and increasing the engine torque.
Standard ModelsStandard EC-60™ controllers support four sensor/fourmodulator (4S/4M) applications. Certain models supportPower Line Carrier (PLC) communications, with all modelssupporting 12 volt installations.
EC-60™ CONTROLLERS WITH PLCSince March 1, 2001, all towing vehicles must have anin-cab trailer ABS Indicator Lamp. Trailers transmit thestatus of the trailer ABS over the power line (the blue wireof the J560 connector) to the tractor using a Power LineCarrier (PLC) signal. See Figures 4 and 5. Typically thesignal is broadcast by the trailer ABS ECU. The applicationof PLC technology for the heavy vehicle industry is knownas “PLC4Trucks.” The Standard PLC EC-60™ controllerand the Premium EC-60™ controller (12 volt versions)support PLC communications in accordance with SAEJ2497.
