Slides of a talk given at ERTS2008 in Toulouse. Abstract: with the increasing amount of electronics, making best usage of the bandwidth becomes of primary importance in automotive networks. One
solution that is being investigated by car manufacturers is to schedule the messages with offsets, which leads to a desynchronization of the message streams. As it will be shown, this “traffic shaping” strategy is very beneficial in terms of worst-case response times. In this slides, the problem of choosing the best offsets is addressed in the case of Controller Area Network, which is a de-facto standard in the automotive world. Comprehensive experiments shown give insight into the fundamental reasons why offsets are efficient, and demonstrate that offsets actually provide a major performance boost in terms of response times. These experimental results suggest that sound offset strategies may extend the lifespan of CAN further, and may defer the introduction of FlexRay and additional CAN networks.

1. Controller Area Network (CAN
bus) in the Automotive Industry
An efficient way to establish in-system communication.
By: BESSAAD NASSIM
2016
2. Introduction:The needs leeds to innovation.
First Approach.
Conception of the CAN bus.
Details about CAN.
CAN in cars.
OBD and CAN.
Conclusion.
PLAN
3. In order to understand the birth of the CAN bus
technology, we must go back in time.
After WWII, most of the military application
manufacturers (tanks, jets, …) switched to cars instead
(Wolkswagen, SAAB..).
The market grew exponentially, the automotive industry
became the heart of the economy, that led to big
competition and rivalry and this naturally leads to new
horizons for the automotive industry.
The car electronics became a large part of the car,
naturally the wiring harness became a problem.
Introductions:
5. The man of the hour was Robert Bosch
It was 1986, Detroit USA, the annual SAE
Congress, Robert Bosch revealed the
Controller Area Network bus system to support short
messages that circulates between the vehicles embedded
systems.
Solution:
8. This is a vehicle bus with:
Serial communication protocole.
Multi-master message model.
System flexibility.
Message anti-collision protection procedure (arbitration).
Communication speed up to 1 Mb/s.
Error detection.
Maximunm network size is limited only by electrical loading.
CAN characteristics:
10. BUS : The physical medium that allows data to find its way
from source to desired destination.
Conception:
11. The CAN is a gathering of nodes without a limited number
of them, but the electrical loading suggests under 70 node
is best.
This nodes communicates using messages called frames
which is a common language for all nodes, the frame has
four types:
DATA FRAME
REMOTE FRAME
ERROR FRAME
OVERLOAD FRAME
Conception
12. The stream of bits in CAN bus is coded according to
the non return to zero (NRZ) methode with bit
stuffing.
after having sending five consecutive bits of identical
value, a stuff bit is added, it’s a bit of inverse value of
the past five. Of course it’s discarded by the receiver.
Conception
14. Controller Area Network 2.0A which is the standard frame
and 2.0B is the extended frame.
The main difference between the A and B is in the message
frame, particularly in the Identifier, the standard CAN 2.0A
uses identification field of 11 bits the extended CAN 2.0B
has a 29 bit Identifier (Arbitration Field).
PS: We can Implement both CAN frame formats in the
same Network with no problems of compatibility.
But if two different format nodes has the same 11 first bits
in the arbitration, the one with CAN 2.0A wins regardless of
the remaining bits of node with CAN 2.0B frame format.
Extended Message format:
16. The microcontroller or the central processing unit:
The brain of the node, it supervise
the communication, sending and
receiving and treating decisions.
CAN controller: responsible of
storing the received bits until a
complete message is available.
The CAN transceiver: it represents
the physical link between the nodes
core and the wires of a bus, it has the role of a converter,
applies the voltage difference on the wires to create the signal to be
transmitted.
CAN node:
17. In CAN we find several error detection procedures:
Bit Monitoring
Compares every bit placed on the CAN bus with the actual bus level
Stuff Check
Compares arriving bit stream for a sequence of six homogeneous bits.
Form Check
Comparison of the arriving bit stream with the message format
Cyclic Redundancy Check
Every node compares the received value of the CRC with the
calculated one it has.
ACK Check
Acknowledge error (ACK error) is detected if the recessive level
placed by the sender is not overwritten.
CAN data protection:
18. Every node has three states:
CAN data protection:
19. Multi-master priority based bus access.
Non-destructive contention based arbitration
Multicast message transfer by message acceptance filtering
Remote data request
Configuration flexibility
System wide data consistency
Error detection and error signaling
Automatic retransmission for message that lost arbitration
Automatic retransmission for message that were destroyed by errors
Distinction between temporary errors and permanent failures of
nodes
Autonomous deactivation of defective nodes
Low-cost, Lightweight network.
CAN proprieties (Advantage):
20. CAN was originally conceived for applications in the
automotive industry, but its grand reliability and flexibility plus
its Baud-rate that generates quick response enabling real-time
application implementation, turn the heads of all area
application designers in order to invest in the efficiency of this
communication protocol.
So, we find today CAN in military, medical, automation …ETC
More than five billions integrated CAN chips are cheeped
every year.
But the automotive industry still the biggest winner for CAN
evolution as we shall see further in this presentation.
CAN applications:
22. The Controller Area Network became an essential for
cars, to understand how big its role we must understand
the cars electronics and evaluate the thing that makes
these machines one of the greatest invention of
mankind.
CAN in automotive
23. The built-in system interface or “BSI” in a vehicle is a gateway
to the diagnostic tool that can incorporate many electronic
modules such as the interface electronics, the control
electronics because it can directly communicate with the
engine ECU and the petrol pump; also it contains
the vehicles information
(VIN code, key code,
HF remote control code…..).
CAN Built-in System Interface:
24. OBD monitors the components that make up the emission
system and key engine components. It can usually detect a
malfunction or deterioration of these components before the
driver becomes aware of the problem.
Since the 1996 model year all vehicles must comply with OBD II
requirements. OBD II requires the monitoring of virtually every
component that can affect the emission performance of a
vehicle plus store the associated fault code and condition in
memory.
On-Board Diagnostic:
25. When the OBD system determines that a problem exists, a
corresponding “Diagnostic Trouble Code” is stored in the
computer memory.
Trouble codes are how OBDII identifies and communicates to
technicians where and what on-board problems exist. The first
number in the DTC indicates whether the code is an SAE
generic code (applies to all OBDII systems) or is specific to the
vehicle manufacturer. The remaining three numbers provide
information regarding the specific vehicle system and circuit.
Theses DTCs comes handy for a technician in order to apply the
necessary maintenance for the car because their interpretation
is universal (generic).
ON-Board Diagnostic Trouble Codes
28. To be able to extract needed data the SAE J1979 standard
define a method for requesting various diagnostic data and a
list of standard parameters that might be available from the
ECU, the available parameters are called Parameter
identification numbers (PIDs).
Every manufacturer has the liberty of changing some listed
PIDs in the SAE J199and add others freely.
The OBD II has (09) nine operation modes.
OBDII:
29. MODE 1:This mode returns certain current values of vehicles sensors.
MODE 2:This mode returns instant data of a malfunction; when a
malfunction is detected by ECU it registers the sensors data at the
moment of the fail appears.
MODE 03:Returns DTC registered, these codes are standardized for all
brands of vehicles.
Mode 04:This mode Allows clearing the stored trouble codes; and
shutting down the malfunction Indicator.
Mode 05:This mode doesn’t use the CAN bus.
OBD II modes:
30. Mode 06:This mode returns the test results of a diagnostic for
ECUs using CAN bus only.
Mode 07:This mode shows pending Diagnostic Trouble Codes
(detected during current or last driving cycle).
Mode 08:This mode shows Control operation of on-board
component/system, not used a lot in Europe.
Mode 09:Returns Vehicles information .
OBD II modes:
31. The request and response uses functional addresses, the
diagnostic tool uses a CAN ID of 0x7DF to broadcast a query
later it accepts 8 ECUs responses using IDs from 0x7E8 to
0x7EF.
The ECU response has an ID of their assigned ID plus 8.
Figure: OBD II query PID on CANbus.
PBD II PIDs:
33. Many contributions affected the automotive industry in the
last century, but the Controller Area Network and On-Board
Diagnostic had a huge impact for what it brought of
advantage for the car manufacturers and the simple
consumer.
Therefore, the development of electronic gadgets based on
those technologies is on the run, we now can diagnose the
car and retrieve many informations easily thanks to those
tools.
