DESCRIPTION
GENERAL
The EC-17
™
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-17
™
controller can be
assembled and programmed to provide an optional traction
control feature. Figure 1 shows the basic EC-17
™
/EC-17N
™
controller configurations.
Designed to minimize the potential of brake lock up on all
wheels during aggressive braking, the EC-17
™
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-17
™
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.
The EC-17
™
controller contains a self configuring or learning
feature that allows it to be configured by the user when
installed on the vehicle. Because of this feature, all EC-17
™
controllers contain all the features and options available and
will activate the specific features required for the vehicle it is
installed on. The EC-17
™
controller can be installed on
vehicles with only antilock or vehicles using the traction
control feature. The procedure for activating the self
configuring feature is contained in the section entitled
“Configuring The EC-17
™
Controller”.
In order to provide full vehicle wheel control antilock, the
EC-17
™
controller is used in combination with the following
components:
- Four or six wheel speed sensors
- Four air pressure modulator valves
- One dash mounted antilock condition lamp
- One service brake relay valve
