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
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.
ESP
is a registered trademark of DaimlerChrysler and is used by BCVS under license from DaimlerChrysler.

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 .

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.
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.
