| For AUTOMOTIVE use |
|
| "FRICO
swiss" controller modules
with useful features:
|
|
|
At least protection class
IP67 for the controller modules and also an expanded temperature range
between –20°C up to +80°C for the functionality of the printed circuit
boards. The units are flexible sealed within a stainless steel cap and
running without an active cooling.
|
|
| No DIP switches or
potentiometers are necessary for configuration of the controller, as a
result of the software configuration menu, running via an external
PC/Notebook. So a simple configuration at customer, garage or in the
office is possible. |
|
|
|
| With ACTROS and MAN (DAF, VOLVO, SCANIA, IVECO in
preparation, RENAULT probably 2005) the following jobs can be realized
via the integrated CAN busses: |
|
|
currently acquisition of the actual velocity,
motor speed and torque |
|
default setting of motor speed and torque |
|
default setting of maximal velocity in standard driving (automatic
speed limits) |
|
application dependent reverse drive lock |
|
and so on (first fusion of vehicle motor with
superstructure) |
|
|
|
|
| With MAN and air spring, it is possible to
invoke the weight of each axis. (MERCEDES starting in 2004) |
|
| During emergency-stop the
controller can be switched off, but it is possible to initiate the
original state as before shut off. (This kind of application should be
state of the art interior the vehicle technology. Applications:
operating the ignition key, pressing emergency-stop, short-circuit or
cable breakage in a cable harness or other mechanical effects. |
|
| During welding the
controller has the same ruggedness as ABS, ASR, engine-, gear- or
other utility vehicle electronics, when installation was proper. |
|
|
Troubleshooting while
cable breakage is possible with usual measure equipment of a mechanical
garage, as for example indicator lamp or beeper – there is no special
equipment necessary.
|
|
| Mechanical touch with
damaging the electronic is impossible because sealing. |
|
| Very large data storage
for long time storage of service information’s and statistical data
acquisition of a great many of different parameters, invoked in the
service garage. It’s imaginable, guarding estimated lifetime of
certain components anࡤࠠwell timed to suggest an exchange,
avoiding breakdown of the vehicle. |
|
| If a controller component
fails instead of highest quality, so repair is possible by the user,
exchanging the defect module only. (Seems only to turn off 4 fitting screws and removing the FCI connector. Node number will be automatically
detected during first switch on.) |
|
| All functions relevant to
security may be realized in double channel. For each function key
it’s possible to have an indicator light, also with background
illumination. |
|
| A programming system in
five different programming languages (FUP, KOP, AWL, ST, AS) based on
IEC 61131-3 is running on every standard personal computer. It is free
buyable and based on an open system solution, that means, also
external products are usable, if they are according the CAN bus
standard. |
|
|
|
| The CPU module is
equipped with three CAN interfaces, so also different external units
are connectable and above all failures of all functions are avoided,
when only one of the bus lines is interfered or if one CAN module
breaks off and has a negative influence to the bus. |
|
| The performance of the
CPU is high enough, to offer a wide range of future applications and
required expansions. So the controller structure is fitted for the
future very well. |

Automotive
assignment
„Till this day control tasks in utility
vehicles are implemented mostly in conventionally contactor
technology or with programmable logic controller for industrial use,
which was not developed for this purpose and so not complies with
the instructions, the requirements and the specification of the
vehicle construction.”
Because the present utility vehicle
superstructures will become more and more pretentious, it is
necessary to increase the use of controller within the
superstructure, handled with more improvement.
An innovative PLC or micro-controller
controls via different peripheral devices the complete
superstructure.
Wiring and communication with sensors /
actuators happens via a CAN field bus system.
|
The
demands
Structure
like chassis electronic, for example injection electronic, motor
control centre (MCC), gearing electronic, anti-lock brake system ABS
or ASR, and so on
Gradual,
order-oriented and extensible structure by modularisation
Practice-oriented,
serviceable products and tools
Programming
in IEC1131‑3 via field bus network
Reasonable,
profitable solutions
Open
control system, supplement by another automation components by means
of open interfaces (CAN/CANopen)
|
 |
The
special technical features
All
outputs are full in electronics realized and short-circuit-proof for
a long time, relays are waste
The
controller is very efficient and enhance able by its modular
structure and the high performance decentralised intelligence
Complete
set-up will be done by software (addresses of the I/O modules)
The
electronic is spilled in a stainless high-grade steel cap and
provided with a self-barred and waterproofed connector,
corresponding IP68

The
controller’s conception
In
marked contrast to traditional controller solutions our structure is
based on the CAN field bus, increasing propagation within the
automotive industry
Interconnection
between the different controlling modules is realized via CAN bus as
well as connection to the central vehicle
The
controller modules are mechanical compact units, mountable according
to vehicle guidelines

Controller
modules
The
controller consists of CPU and In/Out modules
The
CPU module is in its functionality a free programmable micro
controller and emulates the heart of the controller
The
controller is expandable by adding I/O modules. Remote I/O modules
with programmed, but parameterized control tasks and a wide range of
special functions and properties are forming the functionality of
the controller
For
the interconnection of the different modules as well as the
peripheral units there are three galvanic separated CAN busses at
the CPU
CAN
1 for communication with the in/output units
CAN
2 for radio remote control, valve manifold, sensors etc, and
CAN
3 for utility
vehicles chassis
(superstructure
CAN), resp. vehicle central unit, engine electronics
|
Programming
Communication
between programming unit and controller is integrated within the CAN
protocol. So the development system (as a rule a personal computer)
is able to access any CANtrol®
module at the bus. Especially great value took care, to use only
standardized, wide spread development and programming tools
The
controller disposes about a uniformed programming station (PC) for
all bus nodes. Unplugging of the programming station for other bus
nodes is not necessary
The
user is able to program his controller according to the Know-How,
available within the company
He
works according to the programming technique of a PLC: structured
text (ST), statement list (AWL), ladder logic or sequential function
chart (KOP / FUP), obviously according to IEC 61131-3
Via
the programming tool or an menu driven configuration tool running
with Windows98/NT the user selects the application specific module
parameters
