Synopsis The project describes the development and implementation of a
digital driving system for a vehicle. LIN communication protocol is
chosen to realize the objective. The main issues to be considered for the control of a vehicle are
speed control, fuel monitoring, temperature monitoring inside the
vehicle, pressure monitoring of the vehicle tires, engine pressure and
the driver-vehicle interface.
A vehicle was generally built with an analog driver-vehicle interface
for indicating various parameters of vehicle status like temperature,
pressure and speed etc.

Contd«
To improve the driver-vehicle interface, an interactive digital system
is designed.
A microcontroller based data acquisition system that uses ADC to
bring all control data from analog to digital format is used.
Since the in-vehicle information systems are spread out all over the
body of a practical vehicle, a communication module that supports to
implement a one stop control of the vehicle through the master
controller of the digital driving system is used.

Problem statement With rapidly changing computer and information technology and much of
the technology finding way into vehicles, vehicles are undergoing
dramatic changes in their capabilities and how they interact with the
drivers. Although some vehicles have provisions for deciding to either generate
warnings for the human driver or controlling the vehicle autonomously,
they usually must make these decisions in real time with only incomplete
information. So, it is important that human drivers still have some control over the
vehicle. Advanced in-vehicle information systems provide vehicles with
different types and levels of intelligence to assist the driver.

Objective The introduction of digital driving systems into the vehicle design has
allowed an almost symbiotic relationship between the driver and vehicle
by providing a sophisticated & intelligent driver-vehicle interface.
Within this interface, vehicle control depends completely on thecooperation between the driver and the in vehicle information systems
by interactive communication through an intelligent information network.
This project aims to develop such a control framework for the vehicle
which is called the digital-driving behavior, which consists of a jointmechanism between the driver and vehicle for perception, decision
making and control.

ARM PROCESSOR The ARM is a 32-bit reduced instruction set
computer (RISC) instruction set architecture
(ISA) developed by ARM Holdings. It was
known as the Advanced RISC Machine.
The ARM architecture includes some of the
following RISC features:
y Load/store architecture.
y Uniform 16 × 32-bit register file.
y Fixed instruction width of 32 bits.
y Mostly single-cycle execution.

LIN Protocol Controller Area Network (C AN) is a network protocol that allows multiple
processors in a system to communicate efficiently with each other.
LIN makes it possible for all of the separate microprocessors in a system
to send and receive messages without relying on some form of central
control.
A LIN system sends messages using a serial bus network, with the
individual nodes (processors) in the network linked together in a daisy
chain.
Robert Bosch introduced the LIN serial bus system at the Society of
Automotive Engineers (SAE) congress.

Embedded C programming C's primary use is for "SYSTEM PROGRAMMING", including
implementing operating systems and embedded system applications.
It is a combination of desirable characteristics such as code
portability and efficiency and ability to access specific hardware
addresses.
The KEILC Compiler for ARM MCU is a full-featured ANSI compliant
C compiler for the ARM family of 32-bit MCU.

TestingIn our project we intend to use unit testing for the
hardware components.
We use static testing for the software.
A primary purpose for testing is to detect software
failures so that defects may be uncovered and
corrected.

Topic Justification
The title digital driving system was chosen to
indicate the following
Complete digitizing of an automobile.
A LIN system can assist the user to drive his/her
automobile better by using digital systems.
