DESCRIPTION
GENERAL
The EC-16
™
is an electronic antilock controller. It is the base
component in a family of full vehicle wheel control antilock
systems for buses, trucks and truck tractors. In addition to
the antilock function, the EC-16
™ controller can be
assembled and programmed to provide an optional traction
control feature. Figure 1 shows the basic EC-16
™ controller
configuration.
Designed to minimize the potential of brake lock up on all
wheels during aggressive braking, the EC-16
™ controller
based antilock system provides the vehicle with a high
degree of stability and steerability during braking. In most
cases, vehicle stopping distance is also reduced. The
antilock portion of the EC-16
™
controller based system
minimizes wheel skid during hard or aggressive braking. By
controlling wheel skid at all wheels on the vehicle, optimum
steering control and stopping distance is obtained.
Traction control, an optional feature in the full vehicle wheel
control antilock system, helps improve vehicle traction during
acceleration in adverse road conditions. Integrated with
antilock logic, traction control monitors wheel speed
information from the sensors during acceleration, as well as
braking. The system helps maintain vehicle stability on
hazardous road surfaces and improves driveability and safety.
There are two versions of the EC-16 ™ controller. The older
version, was factory pre-programmed with vehicle particulars,
such as the number of speed sensors, if the traction control
feature was enabled and the type of traction control (torque
limiting, differential braking or both). A part number was
assigned to the EC-16
™
controller which was specific for
the programmed features contained in the unit. The newer
version contains a self configuring or learning feature that
allows the EC-16
™
controller to be configured by the user
when installed on the vehicle. Because of this feature, all of
the new version EC-16
™ controllers contain all the features
and options available and will activate the specific features
required for the vehicle it is installed on. The new version
EC-16
™
controller can be installed on vehicles with only
antilock or vehicles using the traction control feature. The
procedure for activating the self configuring feature and
identifying old and new version EC-16
™ controllers is
