main

microcomputer

31

to

a

Wireless

signal

having

a

pre

determined

frequency

(134

kHZ)

and

outputs

the

Wireless

request

signal

from

the

exterior

transmission

antenna

32a

and

the

interior

transmission

antenna

32b.

The

exterior

transmission

antenna

32a

transmits

the

Wireless

request

signal

to

a

predetermined

?rst

area

around

the

vehicle

1.

The

interior

transmission

antenna

32b

transmits

the

Wireless

request

signal

to

a

predetermined

second

area

that

includes

at

least

the

driver

seat

in

the

passenger

compartment.

In

accordance With

certain

output

conditions,

the

main

micro

computer

31

transmits

the

Wireless

request

signal

from

either

the

exterior

transmission

antenna

32a

or

the

interior

transmission

antenna

32b.

[0039]

The

receiving

circuit

33

includes

a

receiving

antenna

33a

for

receiving

an

ID

code

signal

returned

from

the

portable

device

5

in

response

to

the

request

signal.

When

the

receiving

circuit

33

receives

the

ID

code

signal,

the

receiving

circuit

33

demodulates

the

ID

code

signal

to

generate

a

received

signal

and

provides

the

main

microcom

puter

31

With

the

received

signal.

[0040]

The

main

microcomputer

31

includes

a

central

processing

unit

(CPU),

a

read

only

memory

(ROM),

and

a

random

access

memory

(RAM),

and

a

non-volatile

memory

31a.

A

predetermined

ID

code

is

recorded

in

the

memory

31a.

When

the

receiving

circuit

33

receives

the

ID

code

signal

from

the

portable

device

5,

the

main

microcomputer

31

compares

the

ID

code

of

the

ID

code

signal

With

the

ID

code

recorded

in

the

memory

31a

to

perform

ID

code

veri?cation.

Under

the

condition

that

the

ID

codes

match,

the

main

microcomputer

31

controls

the

cover

drive

circuit

13, the

door

lock

driver

44,

the

image

recogniZer

46,

and

the

illumination

device

48.

Based on

the

processing

performed

by

the

main

microcomputer

31,

the

vehicle

1

enters

modes

that

Will

noW

be

discussed

With

reference

to

the

?oWcharts

of

FIGS.

6

and

7.

[0041]

1.

Regular

Mode

[0042]

In

step

S1

of

FIG.

6,

the

engine

is

stopped,

the

doors

are

locked,

and

the

ID

codes

are

not

matched

in

the

passenger

compartment.

In

this

case,

in

step

S2,

the

vehicle

controller

6

transmits

the

request

signal

out

of

the

vehicle

1.

When

the

portable

device

5

receives

the

request

signal,

the

portable

device

5

transmits

the

ID

code

signal.

In step

S3,

the

vehicle

controller

6

veri?es

the

ID

code

With

the

main

microcomputer

31.

When

the

ID

code

of

the

ID

code

signal

matches

the

ID

code

recorded

in

the

memory

31a

of

the

main

microcomputer

31,

the

main

microcomputer

31

pro

vides

the

door

lock

driver

44

With

an

unlock

drive

signal

(step

S4).

Thus,

as

long

as a

user

is

carrying

the

portable

device

5,

the

user

only

has

to

approach

the

vehicle

1

and

does

not

have

to

perform

any

operations

to

unlock

the

doors.

[0043]

When

any

of

the

door

courtesy

sWitches

42

detects

the

operation

(opening

and/or

closing)

of

the

corresponding

door

in

step

S5,

the

vehicle

controller

6

outputs

the

request

signal

in

the

passenger

compartment

in

step

S6. In

other

Words,

When

communication

With

the

portable

device

5

is

established

and

the

doors

are

unlocked,

the

vehicle

control

ler

6

determines

that

communication

has

been

established

With

the

portable

device

5

and

enters

a

regular

mode.

Then,

When

a

door

is

operated

(opened

and/or

closed),

the

vehicle

controller

6

outputs

a

request

signal

in

the

passenger

com

partment.

[0044]

In

response

to

the

request

signal,

the

portable

device

5

transmits

the

ID

code

signal.

When

the

vehicle

Jun.

3,

2004

controller

6

receives

the

ID

code

signal,

the

main

micro

computer

31

veri?es

the

ID

code

in

step

S7.

If

the

ID

code

is

veri?ed,

the

vehicle

controller

6

performs

user

recognition

With

the

image

recogniZer

46

in

step

S8.

More

speci?cally,

the

main

microcomputer

31

provides

the

image

recogniZer

46

With an

activation

signal

to

perform

user

recognition

With

the

image

recogniZer

46.

When

the

authoriZed user

is

con?rmed

through

the

user

recognition

process,

the

vehicle

controller

6

activates the

cover

drive

circuit

13

to

expose

the

operation

board

11

in

step

S9.

In

other

Words,

When

the

main

microcomputer

31

is

provided

With an

electric

signal

indi

cating

that

the

driver

has

been

veri?ed

as

being

the

autho

riZed

user,

the

main

microcomputer

31

provides

the

cover

drive

circuit

13

of

the

drive

system

operation

apparatus

3

With

a

drive

signal

to

move

the

operation

board

cover

12 and

expose

the

operation

board

11

(as

shoWn

in

the

state

of

FIG.

3B).

This

enables

the

operation

of

the

gearshift

operator

14

and

the

engine

sWitch

15.

Thus,

in

the

regular

mode,

the

operation

board

11

is

exposed

and

the

operations

of

the

gearshift

operator

14 and

the

engine

sWitch

15

are

enabled

When

the

conditions

of

communication

being

properly

per

formed

betWeen

the

portable

device 5

and

the

vehicle

controller

6

in

the

passenger

compartment

and

the

autho

riZed

user

being

veri?ed

are satis?ed.

In

this

manner,

the

vehicle

controller

6

enters

a

state

in

Which

engine

starting

is

enabled

in

step

S10.

[0045]

When

the

gearshift

operator

14

is

operated

in

this

state,

a

corresponding

operation

signal

is

provided

to

the

main

microcomputer

31. In

response

to

the

operation

signal

from

the

gearshift

operator

14,

the

main

microcomputer

31

provides

the

SBW

circuit

45

With

a

drive

control

signal

for

sWitching

the

connection

of

the

transmission

to

the

corre

sponding

gearshift

range.

Then,

the

SBW

circuit

45

sWitches

the

connection

of

the

transmission

in

accordance

With

the

drive

control

signal.

Thus,

the

connection

of

the

transmis

sion

is

sWitched

to

a

state

corresponding

to

the

operation

of

the

gearshift

operator

14.

[0046]

The

main

microcomputer

31

does

not

provide

the

SBW

circuit

45

With

the

drive

control

signal

When

the

operation

board

11

is

in a

state

covered

by

the

operation

board

cover

12.

The

main

microcomputer

31

does

not

provide

the

SBW

circuit

45

With

the

drive

control

signal

even

if

an

operation

signal

is

received

from

the

gearshift

operator

14

unless

the

main

microcomputer

31

outputs

the

drive

signal

for

exposing

the

operation

board

11.

In

other

Words,

When

the

main

microcomputer

31

is

not

providing

the

cover

drive

circuit

13 With

the

drive

signal

that

exposes

the

operation

board

11,

the

main

microcomputer

31

invali

dates

the

operation

signal

received

from

the gearshift

opera

tor

14.

Thus,

even

if

the gearshift

operator

14

is

operated

in

a

state

in

Which

the

operation

board

11

is

forcibly

exposed,

such

as

When

the

operation

board

cover

12

is

broken,

the

connection

(gearshift

range)

of

the

transmission

cannot

be

sWitched.

This

improves

the

antitheft

security

of

the

vehicle

1.

[0047]

In

step

S11,

if

the

engine

sWitch

15

is

operated

in

the

state

in

Which

engine

starting

is

enabled,

the

correspond

ing

operation

signal

is

provided

to

the

main

microcomputer

31.

When

receiving

the

operation

signal

from

the

engine

sWitch

15, the

main

microcomputer

31

provides

the

illumi

nation

device

48

With an

activation

signal

and

illuminates

the

instrument

panel

in

step

S12.
