ADVANCED CONTROLLER

INTRODUCTION

The Bendix

EC-60

™

advanced controller is a member

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 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 ESP

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

specic 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 Automatic Traction Control

(ATC). Bendix ATC can improve vehicle traction during

acceleration, and lateral stability while accelerating 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.

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.

(If only two or three connectors are in

use - see SD-13-4863)

The driver is always responsible for the control

and safe operation of the vehicle at all times. The

Bendix

ESP

stability system does not replace the

need for a skilled, alert professional driver, reacting

appropriately and in a timely manner, and using safe

driving practices.
