The Bendix

®

 EC-60

™

 advanced controller is a member 

of a family of electronic 

(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 pressure 

modulator valves, and an ECU to control either four or six 

wheels of a vehicle.  The Bendix EC-60 controller monitors 

individual wheel turning motion during braking and adjusts 

or modulates the brake pressure at the wheel end.  When 

excessive wheel slip, or wheel lock-up is detected, the 

Bendix EC-60 controller will activate the pressure modulator 

valves to automatically reduce the brake pressure at one 

or more of the wheel ends.  By these actions, the ABS 

system helps to maintain the vehicle's lateral stability and 

steerability during heavy brake applications and during 

braking on slippery surfaces.
In addition to the ABS function, advanced models of the 

EC-60

™

 controller provide ABS-based stability features 

referred to as 

 Electronic Stability Program.  The 

Bendix ESP system is an ABS-based stability system that 

enhances vehicle stability by both reducing engine throttle 

and by applying vehicle braking based on actual vehicle 

dynamics.  Accordingly, the ESP system is available only on 

specific approved vehicle platforms after vehicle application 

and development efforts and validation testing.  Only 

certain limited variations of an approved vehicle platform 

are permitted without further validation of the ESP system 

application.
ESP stability system consists of Yaw Control (YC) and Roll 

Stability Program (RSP) features.

Additional features include 

(ATC).  Bendix ATC can improve vehicle traction during 

acceleration, and lateral stability while accelerating through 

curves.  ATC utilizes 

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.  

Advanced Bendix EC-60 controllers have a drag torque 

control  feature which reduces driven-axle wheel slip (due 

to driveline inertia) by communicating with the engine’s 

controller and increasing the engine torque.
For vehicles with the 

Hill Start Feature optional feature, 

this system interfaces between the transmission and 

braking system to help the driver prevent the vehicle from 

rolling downhill when moving up a steep incline from a 

stationary position.

All Four Connectors Are Used.
