1 SCOPE

This chapter is divided into the following paragraphs and subparagraphs.

1.1 Identification

This Software Design Document (SDD) belongs to the “Driving Assistance

System” (DAS).

System title : Driving Assistance System

System abbreviation : DAS

System identification number : 31 000 010

Subsystem title : Safe Drive

Subsystem abbreviation : SD

Subsystem identification number : 31 000 100

CSCI title : On-Board Automobile

CSCI abbreviation : OBA

CSCI identification number : EFX-2003-02

1.2 System overview

The Driving Assistance System (DAS) fits into the framework of “Wawasan

2020”, a Malaysian Government program on the definition and feasibility of

a vehicle for the near future.

The DAS includes the OBA subsystem that shall improve the safety of

vehicle driving, in particular over long trips on highways.

The OBA subsystem shall:

i. Control the cruising speed of the car, upon driver’s request.

ii. Indicate to the driver when maintenance operations are

necessary.

iii. Calculate the average speed on trips, upon driver’s request.

iv. Calculate the average fuel consumption between two fillings

and the average fuel consumption upon a trip.

v. Inform the driver through LED indication for certain

problems detected while driving the vehicle (e.g. via the use

of “Care to speed’ LED).

This subsystem is composed of an embedded computer (the OBA target),

the OBA processor, the OBA software, a control panel and couplers with the

mechanical components of the vehicle.

3 PRELIMINARY DESIGN

This chapter is divided into the following paragraphs and subparagraphs to

describe the preliminary design of the CSCI OBA.

3.1 CSCI overview

This paragraph identifies the CSCI OBA external interface components,

which are described in the following figure.

Figure 3.1: The External Interface Diagram

Figure 3.1 shows the external interface diagram between the CSCI OBA and

the driver. The fuel, gear, keypad and pedal are used by the driver to

interact and give input to the CSCI OBA. The shaft provides the number of

pulses to the CSCI OBA, in order to determine the distance and speed

values. The output of the CSCI OBA is directed to the Safe Drive Control

Panel, which consists of message panel and LED. The throttle receives an

electric voltage, which produced by the fuel inlet mechanism.

Figure 3.2: The CSCI OBA CSCs

Figure 3.2 shows the CSCI OBA CSCs or packages. The CSCI OBA consists

of eight CSCs. Each CSC defines a set of roles, which result in a minimum

of coupling. The CSC is described as following:

1. OBACruise

This CSC is responsible to manage the auto cruise operation. It

consists of the following class:

i. CruiseMgr

2. OBAKeepUpData

This CSC is responsible to hold the updated value of the speed and

distance. It is also responsible to manage the fuel consumption in

terms of filling of fuel and calculation of average consumption. It

consists of the following classes:

i. CalibrationMgr

ii. FuelMgr

3. OBAKernel

This CSC is responsible to provide information on a current value to

the cruise. It consists of the following class:

3.1.2 System states and modes

This paragraph describes the states of each CSCs that operates in the

CSCI OBA. The system states and modes for the CSCI OBA are applied for

the Cruise Control and Maintenance. The state transition is triggered by an

event, which is an occurrence of a stimulus.

The states and modes are visually described in State Transition Diagram.

Refer to Appendix A.

The states and modes are precisely described in the following table.

Mode State Describe

Cruise Control

Cruise disengaged The ignition is on and the auto

cruise is inactive.

Cruise activated The system is under auto

cruise mode.

Accelerate The system speed is increased

upon the driver request by

clicking on the <<Start>>

accelerating button or by

pressing on the accelerator

pedal.

Regulate The system speed is

maintained when the driver do

the following activities:

i. Click the <<Stop>>

accelerating button

ii. Click the <<Resume>>

button.

iii. Release the accelerator

pedal.

Suspend The system is under this state

when the driver presses the

brake pedal.

Cruise deactivated The auto cruise is inactive.

Mode State Describe

Maintenance

Cruise activated The system is under auto

cruise mode.

First level

maintenance

The system is under this state

when the maintenance distance

is 8000km. The maintenance

schedule for this state is to

change the oil and oil filter.

Display message

intermittently

The system reaches 400km

before the maintenance

milestone.

Display message

continuously

The system reaches 80km

before the maintenance

milestone.

Second level

maintenance





change the oil, oil filter and air

filter.

Third level

maintenance





change the oil, oil filter, air

filter and general check.

Table 3.2: System States and Modes for Maintenance

Note:

The maintenance schedule will be continued for every 8000km and will
