A1

controller

23

causes

the

indicator

27

to

?ash

and

the

buzzer

to

go

off

and

immediately

projects

the

portable

device

5

from

the

holder

21.

If

the

holder

21

is

covered

by

the

key

cover

22

before

the

indicator

27

starts to

?ash,

the

key

controller

23

causes

the

indicator

27

to

?ash

and

the

buZZer

to

go

off.

Then,

the

key

controller

23

projects

the

portable

device

5

When

the

holder

21

becomes

eXposed.

Normally,

the

key

cover

22

is

opened

to

eXpose

the

holder

21

When

inserting the

portable

device

5

and

When

getting

out

of

the

vehicle

1.

Automatic

projection

of

the

portable

device

5

When

the

driver

Wishes

to

get

out

the

vehicle

1

makes

the

key

veri?cation

unit

4

more

convenient.

[0060]

When

the

portable

device

5

is

projected

from

the

holder

21,

the

vehicle

controller

6 drives

the

cover

drive

circuit

13

and

covers

the

operation

board

11

in

step

S48.

More

speci?cally,

When

transponder

communication

can

no

longer

be

established

betWeen

the

portable

device

5

and

the

key

controller

23,

the

main

microcomputer

31

provides

the

cover

drive

circuit

13

With

a

drive

signal

to

close

the

operation

board

cover

12

and

cover

the

operation

board

11

(as

shoWn

in

the

state

of

FIG.

3A). This

disables

the

operation

of

the

gearshift

operator

14

and

the

engine

sWitch

15.

In

the

irregular

mode,

under

the

condition

that

transpon

der

communication

is

not

established

betWeen

the

portable

device

5

and

the

key

controller

23,

the

operations

of

the

gearshift

operator

14

and

the

engine

sWitch

15

are

disabled.

[0061]

When

the

door

is

locked

by

a

mechanical

key

or

the

like

in

step

S49,

the

vehicle

1

returns

to

the

state

of

step

S31.

[0062]

The

preferred

embodiment

has

the

advantages

described

beloW.

[0063]

(1)

To

operate

the

gearshift

operator

14

and

the

engine

sWitch

15,

communication

betWeen

the

portable

device

5

and

the

vehicle

controller

6 or

the

key

veri?cation

unit

4

must

be

established.

Further,

the

image

recogniZer

46

must

verify

that

the

driver

is

the

authoriZed

user.

That

is,

to

drive

the

vehicle

1,

in

addition

to

holding

the

portable

device

5,

the

driver

must

have

his

or

her

image

registered

before

hand.

This

prevents

a

third

person

from

driving

the

vehicle

1

even

if

he

or

she

is

carrying

the

portable

device

5.

Thus,

basically

only

the

user

can

drive

the

vehicle

1.

[0064]

(2)

In

the

normal

mode,

that

is,

When

the

doors

are

unlocked

through

communication

betWeen

the

portable

device

5

and

the

vehicle

controller

6,

the

image

recogniZer

46

is

activated

When

communication

is

established

betWeen

the

portable

device

5

and

the

vehicle

controller

6

in

the

passenger

compartment.

In

the

irregular

mode,

that

is,

When

the

doors

are

unlocked

by

a

mechanical

key

or

the

like,

the

image

recogniZer

46

is

activated

When

communication

is

established

betWeen

the

portable

device

5

and

the

key

veri?cation

unit

4.

Accordingly,

the

image

recogniZer

46

is

activated

at

different

timings

in

the

regular

mode

and

the

irregular

mode.

The

image

recogniZer

46

is

activated

only

When

necessary

in

each

mode.

This

prevents

unnecessary

activation

of

the

image

recogniZer

46

and

decreases

the

poWer

consumption

of

the

image

recogniZer

46.

[0065]

If

the

activation

timing of

the

image

recogniZer

46

in

the

regular

mode

and

the

irregular

mode

Were

the

same,

for

eXample,

if

the

image

recogniZer

46

Were

to

be

activated

after

unlocking

the

doors

in

both

modes,

the

image

recog

niZer

46

Would

be

activated

regardless

of

Whether

or

not

the

user

gets

into

the

vehicle

1.

In

such

a

case,

the

image

Jun.

3,

2004

recogniZer

Would

be

activated

in

an

unnecessary

manner

and

unnecessary

poWer Would

be

consumed.

[0066]

(3)

Subsequent

to

the

opening

of

a

door

in

the

regular

mode,

the

main

microcomputer

31

activates

the

image

recogniZer

46

When

transmitting

the

request

signal

in

the

predetermined

area

of

the

passenger

compartment

in

the

vehicle

and

receiving

the

ID

code

signal

from

the

portable

device

5.

Thus,

the

image

recogniZer

46

is

activated

only

When

the

user

enters

the

vehicle

1.

This

reduces

the

amount

of

poWer

consumed

by

the

image

recogniZer

46.

[0067]

(4)

The

key

cover

22

covers

the

holder

21.

If

the

key

cover

22

is

opened

to

eXpose

the

holder

21

When

the

portable

device

5

is

held

in

the

holder

21

and

the

engine

is

stopped,

the

portable

device

5

is

automatically

projected

from

the

holder

21.

Normally,

the

key

cover

22

is

moved

to

eXpose

the

holder

21

When

inserting the

portable

device

5

and

When

getting

off

the

vehicle

1.

The

automatic

projection

of

the

portable

device

5

When

the

user

get

out

the

vehicle

1

makes

the

key

veri?cation

unit

4

convenient

and

easy

to

operate.

[0068]

(5)

When

the

portable

device

5

is

inserted

in

the

key

receiver

21a

of

the

holder

21,

the

portable

device

5

is

automatically

retracted

into

the

holder

21.

This

ensures

and

facilitates

the

retraction

of

the

portable

device 5

in

the

holder

21.

Thus,

the

key

veri?cation

unit

4

is

easy

to

operate.

[0069]

(6)

If

the

engine

is

stopped

When

the

holder

21

is

in

an

eXposed

state,

the

portable

device

5

is

automatically

projected

from

the

holder

21

as

the

engine

stops.

In

other

Words,

even

if

the

vehicle

is

driven

Without

closing

the

holder

21

With

the

key

cover

22,

the

portable

device

5

is

automatically

projected

When

the

engine

is

stopped.

This

makes

the

key

veri?cation

unit

4

easy

to

operate.

[0070]

(7)

The

operation

board

cover

12

covers

the

gear

shift

operator

14

and

the

engine

sWitch

15,

Which

are

operated

to

drive

the

vehicle

1.

This

prevents

a

third

person

from

operating

the

gearshift

operator

14 and

the

engine

sWitch

15.

Further,

the

gearshift

operator

14 and

the

engine

sWitch

15

cannot

be

seen

from

outside

the

vehicle

1.

This

helps

to

lessen

a

third

person’s

incentive

to

break

into

the

vehicle

1

and

improves

the

security

level

of

the

vehicle

1.

Further,

the

close

location

of

the

gearshift

operator

14

and

the

engine

sWitch

15

facilitate

their

operations.

[0071]

(8)

The

operation

board

cover

12

does

not

eXpose

the

gearshift

operator

14

and

the

engine

sWitch

15

unless

communication

is

established

betWeen

the

portable

device

5

and

the

vehicle

controller

6 or

the

key

veri?cation

unit

4.

This

prevents

someone

other

than

the

user

from

operating

the gearshift

operator

14

and

the

engine

sWitch

15

and

improves

the

security

level

of

the

vehicle

1.

[0072]

(9)

The

parking

sWitch

14a

and

the gearshift

sWitch

14b

operate

the

transmission,

and

the

engine

sWitch

15

starts

and

stops

the

engine.

In

comparison

With

the

mechanical

gearshift

operator

and

engine

operator

of

the

prior

art

such

as

a

gearshift

lever

and

an

ignition

key

cylinder,

the

parking

sWitch

14a,

the gearshift

sWitch

14b,

and

the

engine

sWitch

15 have

a

more

simple

and

compact

structure.

Further,

the

positions

of

the

sWitches

14a, 14b,

and 15

may

be

deter

mined

With

a

high

degree

of

freedom.
