2. ABSTRACT
The system consists of a vehicle-to-driver and a vehicle-to-
environment communication mechanism, which is based on
a smartphone core and on a wireless Bluetooth medium.
The driver-to-vehicle interaction is based on an audio
interaction located at helmet level. The driver-to-
environment is represented by communication via the HTTP
protocol.
The vocal synthesis, the speech recognition, and the gateway
to the web server are implemented on the smartphone.

3. INTRODUCTION
 The system is targeted to increase the safety level of a
motorcycle.
On one hand, motorcycles are means for personal
mobility with a low environmental impact due to the
relatively low weight, and they seem to be extremely
promising for the development of electric vehicles. On
the other hand, they are responsible for about 20% of
road incidents due to a relatively low level of safety.
 This system capable of implementing a bidirectional
audio interaction with the driver and to provide remote
monitoring of the vehicle parameters.

4. HUMAN MACHINE INTERFACE
 A common smart- phone can be used, it usually includes a
3G connection as a wireless communication.
The architecture is completed by a CAN-
Bluetooth converter and an off-the-shelf audio helmet with
Bluetooth interface.
The smartphone may be viewed intrinsically as a “plug and
play” smart gateway. This kind of use of a mobile device
may be extremely intriguing, although the literature usually
puts the focus on the HMI capability of smartphones.

5. SYSTEM ARCHITECTURE AND HARDWARE
 A motorcycle natively equipped with a vehicle control unit
(VCU) collects the data from the vehicle, controls the engine
and displays the relevant information on the dashboard.
An embedded electronic unit interfaced to the CAN bus of
the vehicle, and capable of collecting optional analog and
digital signals.
A helmet with audio speakers and a microphone. The audio
signals may be transmitted over a Bluetooth channel by the
embedded transceiver of the helmet.
The mobile device also includes a processor which can
handle the audio and vocal synthesis, and the information
management.

6. Embedded Electronic Unit for the CAN-Bluetooth Gateway
The vehicle embedded electronic system acts as
a gateway between the CAN bus and the
Bluetooth channel.
This consist of two modules
a) Two-layered main board
b) Bluetooth add-on

7. SYSTEM ARCHITECTURE

8. SOFTWARE ARCHITCTURE
There are four layers in system architecture
a)Motorcycle layer
b)CAN-Bluetooth Gateway layer
c)The smartphone layer
d)The helmet layer

9. MOTORCYCLE LAYER
The motorcycle is natively equipped with a VCU
manages the vehicle and collects the data.
The information interface is constituted by a bus,
according to the CAN protocol.
The VCU may send messages through it (vehicle
sensing), and may act on the basis of the
messages that it reads (actuation).

10. CAN-BLUETOOTH GATEWAY LAYER
The CAN-Bluetooth gateway filters and sends the
information over the CAN bus according to the database
of accessible information.
The measurements of the vehicle are translated into
notifications, and the commands are turned into
commands to VCU.
 There is a clear tradeoff between the general load of
information and the load capacity of the Bluetooth
channel.

11. THE SMARTPHONE LAYER
It represents core of the system, the interface
between the mobile device and the gateway is
implemented with the SPP(serial port profile)
over Bluetooth.
The smartphone also manages the communica-
tion to and from the web server (remote point)
according to the HTTP protocol.

12. THE HELMET LAYER
It provides the audio interface to the driver by
the means of an integrated headset. The helmet
also includes a Bluetooth module implementing
the HFP(hands free profile) layer for the
interface to the smartphone.
It converts also the smartphone audio stream into
an audio signal for the driver.

13. System architecture

14. ADVANTAGES
It is very efficient method.
It is reliable and less sensitive method.
This method is very useful for avoiding
road incidents and also increasing the
baud rate.
There is no interference occur in this
method.

15. APPLICATIONS
This method is used for interfacing the
smartphone with the driver-to-motorcycle
interface.
With the help of smartphone app we can use this
system in anywhere at every time.
By using this method we can interface helmet
with motor cycles .so, the user can communicate
with environment.

16. FUTURE SCOPE
In this method transfer of data from
vehicle to smartphone by using
Bluetooth, it is only used for small
distance(10m) only.But by using zigbee
for transferring the data from vehicle to
smartphone with high baud rate.

17. CONCLUSION
 This method based on a smartphone core and on
a wireless Bluetooth medium.
Once the CAN dictionary of the motorcycle is
defined, the system may be plugged and played.
 This makes the architecture interesting for
practical applications and product development.
