The document discusses Controller Area Network (CAN) bus, which is a vehicle bus standard that allows microcontrollers and devices to communicate with each other within a vehicle without a host computer. Key points:
- CAN bus uses a serial communication protocol and multi-master message model to allow nodes to transmit and receive messages.
- It employs a bus topology where nodes are connected to a single cable with termination resistors at each end to eliminate signal reflections.
- CAN bus is used widely in automotive applications but also in other industries like shipping, manufacturing, etc. due to its robustness, error detection and flexibility.
This document describes a vehicle monitoring system that uses PIC microcontrollers and the Controller Area Network (CAN) protocol.

The PICs communicate over CAN to send sensor data from the engine to be displayed on the dashboard. The system was implemented using hardware circuits and software programmed with MPLab IDE.
Controller Area Network is an ideal serial bus design suitable for modern embedded system based networks.

Solution
There are four main applications for serial communication in vehicles, each having different
requirements and objectives.
Using CAN, peer stations (controllers, sensors and actuators) are connected via a serial bus. The
bus itself is a symmetric or asymmetric two wire circuit, which can be either screened or
unscreened. The electrical parameters of the physical transmission are also specified in ISO
11898. Suitable bus driver chips are available from a number of manufacturers.
The CAN protocol, which corresponds to the data link layer in the ISO/OSI reference model,
meets the real-time requirements of automotive applications. Unlike cable trees, the network
protocol detects and corrects transmission errors caused by electromagnetic interference.
Additional advantages of such a network are the easy configurability of the overall system and
the possibility of central diagnosis.The purpose of using CAN in vehicles is to enable any station
to communicate with any other without putting too great a load on the controller computer.
Principles of data exchange.
When data are transmitted by CAN, no stations are addressed, but instead, the content of the
message (e.g. rpm or engine temperature) is designated by an identifier that is unique throughout
the network. The identifier defines not only the content but also the priority of the message. This
is important for bus allocation when several stations are competing for bus access.
If the CPU of a given station wishes to send a message to one or more stations, it passes the data
to be transmitted and their identifiers to the assigned CAN chip (”Make ready”). This is all the
CPU has to do to initiate data exchange. The message is constructed and transmitted by the CAN
chip. As soon as the CAN chip receives the bus allocation (”Send Message”) all other stations on
the CAN network become receivers of this message (”Receive Message”). Each station in the
CAN network, having received the message correctly, performs an acceptance test to determine
whether the data received are relevant for that station (”Select”). If the data are of significance
for the station concerned they are processed (”Accept”), otherwise they are ignored.
A high degree of system and configuration flexibility is achieved as a result of the content-
oriented addressing scheme. It is very easy to add stations to the existing CAN network without
making any hardware or software modifications to the existing stations, provided that the new
stations are purely receivers. Because the data transmission protocol does not require physical
destination addresses for the individual components, it supports the concept of modular
electronics and also permits multiple reception (broadcast, multicast) and the synchronization of
distributed processes: m.
The document discusses a VLSI Bluetooth baseband controller chip developed by Ericsson and VLSI for use in portable Bluetooth devices. The chip is based around an ARM7TDMI processor core and includes Bluetooth radio interface logic. It supports ad-hoc Piconet networks of 2-8 devices and can link multiple Piconets. The chip includes power management modes for low power operation and requires an external radio module to complete the system.
In this AUTOSAR layered architecture, Communication Stack or ComStack facilitates communication. Hence ComStack can be defined as a software stack that provides communication services to the Basic Software Modules and Application Layer or Application Software.

This document summarizes a research paper that designed and implemented a vehicle theft control unit using GSM and CAN technology. The system uses an embedded system with a GSM module installed in the vehicle that is interfaced with the engine control module via the CAN bus. The GSM module allows the owner to remotely lock or unlock the engine via mobile phone. An RFID reader is also used to detect nearby locations like hospitals, schools, etc. based on RFID tags placed along roads. If intrusion is detected, an SMS alert is sent to the owner. The system was designed and tested using Keil software. It provides a low-cost solution to vehicle theft compared to advanced GPS-based systems.

to communicate with any other without putting too great a load on the controller computer.
Principles of data exchange.
When data are transmitted by CAN, no stations are addressed, but instead, the content of the
message (e.g. rpm or engine temperature) is designated by an identifier that is unique throughout
the network. The identifier defines not only the content but also the priority of the message. This
is important for bus allocation when several stations are competing for bus access.
If the CPU of a given station wishes to send a message to one or more stations, it passes the data
to be transmitted and their identifiers to the assigned CAN chip (”Make ready”). This is all the
CPU has to do to initiate data exchange. The message is constructed and transmitted by the CAN
chip. As soon as the CAN chip receives the bus allocation (”Send Message”) all other stations on
the CAN network become receivers of this message (”Receive Message”). Each station in the
CAN network, having received the message correctly, performs an acceptance test to determine
whether the data received are relevant for that station (”Select”). If the data are of significance
for the station concerned they are processed (”Accept”), otherwise they are ignored.
A high degree of system and configuration flexibility is achieved as a result of the content-
oriented addressing scheme. It is very easy to add stations to the existing CAN network without
making any hardware or software modifications to the existing stations, provided that the new
stations are purely receivers. Because the data transmission protocol does not require physical
destination addresses for the individual components, it supports the concept of modular
electronics and also permits multiple reception (broadcast, multicast) and the synchronization of
distributed processes: m.

This document summarizes a research paper that designed and implemented a vehicle theft control unit using GSM and CAN technology. The system uses an embedded system with a GSM module installed in the vehicle that is interfaced with the engine control module via the CAN bus. The GSM module allows the owner to remotely lock or unlock the engine via mobile phone. An RFID reader is also used to detect nearby locations like hospitals, schools, etc. based on RFID tags placed along roads. If intrusion is detected, an SMS alert is sent to the owner. The system was designed and tested using Keil software. It provides a low-cost solution to vehicle theft compared to advanced GPS-based systems.

1. Everything You Need to Know
About Controller Area Network
If you're working with a product that has some sort of control system in it, you've
probably run into the acronym CAN, which stands for Controller Area Network. What
is CAN? Embeddedone is a specialized Embedded Software Development
Company. Here's everything you need to know about this useful protocol and how it
works.
Introduction
A controller area network (CAN bus) is a vehicle bus standard designed to allow
microcontrollers and devices to communicate with each other in applications without
a host computer. It is a message-based protocol, designed originally for multiplex
electrical wiring within automobiles to save on copper, but can now be found in many
other applications. In this post, we'll give you an overview of the CAN bus, explain
how it works, and provide some examples of its most common uses.
How CAN Works
Controller Area Network (CAN) is a vehicle bus standard designed to allow
microcontrollers and devices to communicate with each other in applications without
a host computer. CAN is a message-based protocol designed specifically for
2. automotive applications. It supports multiple message types, including broadcast
messages, which can be sent to all nodes on the network, and unicast messages,
which are sent to specific nodes. The standard defines four different frame types:
data frames, remote frames, error frames, and overload frames. Data frames are
used to transfer information between nodes on the network. Remote frames provide
fault isolation and signal when one node sends an error frame or overload frame to
another node. Error frames indicate that an invalid message has been received by a
node. Overload frames indicate that a node has exceeded its capacity, while they do
not provide any additional information about why this occurred.
Advantages of CAN Bus
1. A controller area network (CAN bus) is a vehicle bus standard designed to allow
microcontrollers and devices to communicate with each other in applications without
a host computer.
2. CAN bus is a message-based protocol designed specifically for automotive
applications.
3. The main advantage of the CAN bus is that it allows all devices on the network to
share information and communicate with each other without the need for a central
computer.
4. This means that the CAN bus can be used in a wide variety of applications, from
simple sensor networks to complex automotive systems.
5. CAN bus is also very versatile, able to support both simple and complex data
types.
History of CAN Bus
The Controller Area Network bus was originally developed in the 1980s by Robert
Bosch GmbH for use in the automotive industry. The CAN bus was designed to be a
robust, fault-tolerant system that could connect various electronic components in a
vehicle and allow them to communicate with each other. It operates at speeds of up
to 1Mbit/s while still being highly efficient. It is primarily used in cars, trucks, boats,
aircraft, and heavy machinery but can also be found in many industrial automation
systems such as conveyor systems.
A CAN network consists of two types of nodes: the controller nodes, which are
connected directly to the network media (usually twisted pair), and terminal nodes,
which interface controllers to outside equipment via serial interfaces such as RS232
or RS485. Node configuration options include full duplex communication between all
nodes on the bus or half-duplex communication where one node transmits at a time
on the shared medium with repeaters needed for extended distances between node
pairs.
CAN Bus vs. Ethernet
3. Controller Area Network (CAN) is a vehicle bus standard designed to allow
microcontrollers and devices to communicate with each other in applications without
a host computer.
Ethernet is a computer networking protocol for local area networks (LANs). It was
originally developed by Xerox Corporation in the 1970s.
CAN Bus is faster than Ethernet, but it uses more power. Ethernet is cheaper and
easier to install, but it is not as fast.
Advantages & Disadvantages of CAN Bus Technology
Controller Area Network (CAN) bus technology was developed in the 1980s by
Robert Bosch GmbH. The main advantage of the CAN bus is that it reduces wiring
complexity compared to other methods such as point-to-point connections. This is
because each node on a CAN network can communicate with every other node,
making it ideal for large networks. Additionally, the CAN bus is very rugged and can
operate in harsh environments. However, one downside of the CAN bus is that it is
not compatible with standard Ethernet networks.
Types of CAN Protocols in Auto Industries
There are three types of CAN protocols in automotive industries. They are named
according to the number of wires in the system.
The first is Single-wire CAN, which uses a single twisted pair of wires. The second is
Dual-wire CAN, which uses two pairs of wires. The last is High-speed CAN, which
can use multiple pairs of wires.
All three types of CAN protocols are used in different applications within the
automotive industry. Single-wire CAN is used for lighting control and body control
applications. Dual-wire CAN is used for powertrain and chassis control applications.
High-speed CAN is used for infotainment and telemetry applications.
What is the controller area network?
Controller Area Network, or CAN, is an electronic protocol that allows different
electronic devices to communicate with each other using cables. It was originally
designed by Bosch and Siemens in 1985 and standardized as ISO 11898 in 1994.
The protocol allows for data transmission rates of up to 1 Mbit/s, which makes it an
ideal option for small networks of devices such as those found in motor vehicles and
industrial applications. In this article, we'll take a look at how the protocol works and
what makes it so reliable and efficient.
4. No configuration
A Controller Area Network (CAN bus) is a vehicle bus standard designed to allow
microcontrollers and devices to communicate with each other in applications without
a host computer. CAN buses are used in vehicles, industrial automation, medical
equipment, and other applications. Devices that are connected to the CAN bus are
called nodes. Nodes can be controllers, sensors, actuators, or other devices. The
two types of the node defined by the standard are the master node and slave node.
The master node initiates messages on the bus and assigns IDs to slave nodes; it
may also send periodic messages to inform slaves of its existence, which avoids
conflicts when more than one Master exists on a single CAN network. Slave nodes
listen for messages from masters or other slaves and respond if necessary but do
not initiate message transmission. Some messages have timeouts so that they will
eventually terminate even if no response is received; this allows slaves that have
missed previous messages to catch up after being reset or powered off. All CAN
networks have one primary Master and at least one Slave; additional Masters may
exist on some networks, but there should never be more than one primary Master
per network.
Several vendors
Controller Area Network (CAN) was originally developed in the 1980s by Robert
Bosch GmbH for the automotive industry. The aim was to create a standardized,
reliable, and cost-effective way to allow electronic devices to communicate with each
other in a vehicle. Today, CAN is used extensively in many industries and
5. applications, including automotive, aerospace, industrial automation, medical
devices, and more. For example, systems that monitor blood glucose levels require
very small amounts of energy from the subject. These sensors can be embedded in
clothing or worn on the arm.
Interoperability
Controller Area Network (CAN) is a standard for communication protocols in
electronic control units (ECUs). It was originally designed for the automotive industry
but has since been adopted by other industries such as aerospace, medical, and
industrial automation. CAN allows devices to communicate with each other without
the need for a central computer. This makes it ideal for applications where distributed
control is required, such as in-vehicle networks or industrial automation systems.
The two types of messages supported are received and transmitted. Messages are
sent out from one ECU (the Master), which then transmits them to all connected
ECUs on the network. These messages can either be one-time transmissions if only
used for a single data transfer, or they can be the recurring transmission if used over
an extended period of time. Both message types also have their own separate
address format that needs to be assigned before they are transmitted.
Low cost of entry
Controller Area Network (CAN) is a low-cost-to-entry, high-speed communication bus
used in automotive and industrial applications. It was originally designed for use in
automotive applications but has since been adopted by the industrial sector as well.
CAN is used to connect devices such as sensors, actuators, and controllers to create
a distributed control system. The low cost of entry makes it an attractive option for
small businesses and hobbyists alike. There are two types of CAN communications:
on-board and off-board. On-board uses an embedded microcontroller to
communicate with nearby modules, while off-board uses wires or cables to
communicate between modules that are farther away from each other. Off-board
typically relies on dedicated chips that have more capabilities than their embedded
counterparts because they lack constraints like size, power consumption, operating
temperature range, etc.
Fast connection speeds
The Controller Area Network (CAN) is a high-speed serial data bus used in vehicles.
It was originally designed for the automotive industry, but it has also been used in
other industries such as aerospace and industrial automation. The CAN bus allows
devices to communicate with each other without the need for a central computer.
This makes it ideal for applications where real-time data needs to be exchanged
between devices. One of the main advantages of using a CAN bus over an Ethernet
connection is that there are no collisions on this network. A collision occurs when two
devices try to send information at the same time, resulting in both packets being
6. corrupted or lost. Because there are no collisions on this type of system, it's very
reliable and provides better performance than other networks.
