INTRODUCTION
Bendix
®
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) by
communicating with the engine’s controller and increasing the
engine torque.
