HSA interfacesįIGURE 1 - BENDIX ® EC 80 ™ ABS AND ATC CONTROLLERS 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.īendix EC 80 ATC controllers also have the capability to provide a Hill Start Assist (HSA) feature. Bendix ® ATC can improve vehicle traction during acceleration, plus lateral stability while driving through curves. In addition to the ABS function, the ATC version of the Bendix EC 80 controller provides an Automatic Traction Control (ATC) feature. However, the Bendix EC 80 controller is able to pump the brakes on individual wheels (or pairs of wheels) independently, and with greater speed and accuracy than a driver. When excessive wheel slip, or wheel lock-up is detected, the Bendi圎C 80 controller will activate the Pressure Modulator Valves to simulate a driver pumping the brakes. By monitoring individual wheel turning motion during braking, and adjusting or pulsing the brake pressure at each wheel, the Bendix EC 80 controller is able to optimize slip between the tire and the road surface. ABS controllers are also known as Electronic Control Units (ECUs).īendix ® ABS uses wheel speed sensors, ABS modulator valves, and an ECU to control either four or six wheels of a vehicle.

See SD-13-21021 for the Bendix ® eTrac ™ Automated Air Suspension Transfer Systemīendix ® EC 80 ™ ESP(+) Controllers will be featured in SD 13-4986.īendix ® EC 80 ™ ABS and ATC 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 heavyand medium-duty buses, trucks, and tractors.
