INTRODUCTION
The Bendix
®
EC-30
™
is an electronic ABS (antilock braking
system) controller. It is the base component in a family of
ABS assemblies for heavy and medium duty buses, trucks
and tractors utilizing pneumatic braking systems.
ABS assemblies for heavy and medium duty buses, trucks
and tractors utilizing pneumatic braking systems.
The ABS function of the EC-30
™
controller is designed to
optimize slip on all vehicle wheels. The EC-30
™
controller
provides the vehicle with improved stability and steerability
during braking. The EC-30
during braking. The EC-30
™
controller will also reduce vehicle
stopping distance on most surfaces.
In addition to the ABS function, the EC-30
™
controller can
be configured to provide an ATC (automatic traction control)
feature. Bendix ATC can improve vehicle traction during
acceleration on adverse road conditions. ATC can utilize
engine torque limiting and/or differential braking to improve
vehicle traction.
