Title of the invention

ANTENNA MODULE FOR REMOTE ENGINE STARTING OF VEHICLE

AND METHOD FOR DISPLAYING VEHICLE INFORMATION USING THE

ANTENNA MODULE

Field of the invention

The present invention relates to an antenna module for remote engine starting

and method for displaying vehicle data using the antenna module, especially, an antenna

module and method enabling a user to easily control the functions of vehicle by

providing vehicle data on the antenna module of remote engine starting and alarm

system.

Background of the present invention

Generally, a remote starting and alarm system enables a driver to start engine by

operating a transmitter at the outside of vehicle so that the driver can drive the vehicle

as soon as he gets on the vehicle.

The conventional remote starting and alarm system comprises a main unit being

installed on the vehicle for controlling the vehicle equipments and a remote controller

being carried by the driver, both can communicate with each other bi-directionally or

uni-directionally. The antenna locating between the remote controller and the main unit relays a signal from one to another.

If the driver controls the operation of vehicle(e.g., remote starting) by means of

the remote controller, the main unit receives a remote control signal of the remote

controller via an antenna, and performs an operation corresponding to the received

remote control signal.

That is, when the driver pushes a button according to the predetermined

ways(e.g., long, short, once or several times), then a micro-processor in the remote

controller generates the predetermined signal for remote control. The generated remote

control signal is transmitted through RF circuit, and then received by the antenna. When

the antenna delivers the received signal to the main unit, the main unit performs the

vehicle control corresponding to the received signal. The main unit transmits the result

of operation to the remote controller via the antenna, if necessary.

Also, if a theft or an attempt of robbery may occur, the main unit of the

conventional remote starting and alarm system generates an alarming sounds, and at the

same time, transmits the occurrence of theft to the remote controller in order to prevent

the theft.

As described above, the conventional remote starting and alarm system relays

signals between the remote controller and the main unit, but cannot provide any data

about the vehicle condition or the current setup state of alarm system. Also, it is difficult

for the driver who lost the remote controller to change the function setup of main unit. In addition, in the case of changing the function setup of main unit even by the remote

controller, some problems in data recognition can occur due to the limitation on the

effective distance for transmission and errors occurring communication.

Also, due to the simple function of the antenna in the conventional remote

starting and alarm system, it is cumbersome to additionally connect the main unit with a

carcall sensor(i.e., theftproof sensor) for calling a driver.

Embodiments

Hereinafter, an antenna module for remote engine starting of vehicle and

method for displaying vehicle data using the antenna module will be described with

accompanying drawings. In describing the accompanying drawings, same or equivalent

element will be indicated by same reference number throughout whole drawings, and

repeated description will be omitted. Also, although the spirit of present invention will

be described with embodiments, however, it is an exemplary only, not for limit, and it is

apparent to those who skilled in the art that various changes and modification can be

made without departing from the spirit and scope of the present invention.

FIG 1 is a block diagram of remote starting and alarm system according to the

preferred embodiment of the present invention. Referring to FIG. 1 , the remote starting

and alarm system comprises a remote controller 120, a vehicle antenna 130 and a main unit 140.

The remote controller 120 is a portable device for remotely controlling a remote

starting, a door lock/unlock, an alarm setup of vehicle 110 at the outside. The remote

controller 120 can further comprise a display for showing setup condition data of

vehicle 110 being received from the main unit 140 through bi-directional

communication.

The vehicle antenna 130 relays the bi-directional communication between the

remote controller 120 and main unit 140. That is, the vehicle antenna 130 delivers the

vehicle control signal received from the remote controller 120 by means of RF

transmission method to the main unit through a cable, and the operation result data from

the main unit 140 to the remote controller 120 by means of RF transmission method.

Also, the vehicle antenna 130 comprises a display for showing vehicle condition data

and a key button for controlling the vehicle condition(e.g., theftproof setup, alarm setup,

door unlock, open trunk, etc.). The configuration and operation of vehicle antenna 130

will be described in detail with drawings.

The main unit 140 controls the condition of vehicle 110 according to the vehicle

control signal from remote controller 120 via the vehicle antenna 130 or the vehicle

control signal from the key button in the vehicle antenna 130. The main unit 140 will be

connected temporarily to the door lock/unlock device or engine star switch to perform

the vehicle control operation according to the vehicle control signal. Since the connections between the main unit 140 and the vehicle devices for remote controlling

are well known in the art, detailed description will be omitted here.

FIG 2 is a block diagram of the vehicle antenna according to the preferred

embodiment of the present invention.

Referring to FIG 2, the vehicle antenna 130 of the present invention comprises

a power supply 210, an input device 220, a carcall detector 230, a main unit interface

240, an oscillating circuit 250, a display 260, a RF transducer 270 and a controller 280. The power supply 210 provides an electrical power to the vehicle antenna 130.

The power supply 210 is a battery installed in the vehicle 110 or contained in the

vehicle antenna. Also, the power supply 210 can be the battery in the vehicle during

driving or the self-containing battery during parking.

The input device 220 comprises at least one button for controlling to display

vehicle condition data(e.g., car temperature, remaining power of self-containing battery,

and so on) or changing vehicle setup condition data(e.g., sensitivity of carcall detector,

current time setting, temperature displaying way, and so on). The way of button

comprised in the input device 220 will be described in detail with accompanying

drawing.

The carcall detector 230 comprises a carcall LED, a carcall sensitivity

controller, and a sensor. The carcall function in the vehicle antenna 130 according to the present invention is to notify an occurrence of impact with more than the predetermined

magnitude on vehicle 110 to the driver via the main unit 140 and at the same time to

generate an alarm sound on a speaker of vehicle 110(i.e., antitheft function). The carcall

LED in lighting mode indicates door opening(theft) or impact detection mode. Also, if

an impact larger than the predetermined magnitude is detected, the carcall LED lights to

warn. Of course, the display 260 can perform the same function of the carcall LED, so

the carcall LED can be omitted. The carcall sensitivity controller provides a means for

the driver to control the sensitivity of carcall. For example, the carcall sensitivity

controller can comprise two selection modes: "LOW" mode and "HIGH" mode. The

sensor detects the impact on vehicle or door opening. On detecting the impact or door

opening, then the sensor sends a detection signal to the controller 280 so that the

detection signal can be transmitted to the remote controller 120 and at the same time the

carcall LED or display can perform the alarm operation. Also, the speaker being

connected to the main unit 140 can generate the alarm sound. Of course, when the

controller 280 receives the detection signal for the impact or door opening from the

sensor, the controller 280 can determine whether or not the magnitude of impact is

larger than the predetermined magnitude to perform the antitheft operation(e.g., alarm

sound, driver call).

The main unit interface 240 is for connecting the vehicle antenna 130 and the

main unit 140 in the vehicle 110 via wired or wireless way. Namely, the main unit interface 240 delivers the control signal from the remote controller 120 to the main unit

140 and receives the operation result from the main unit 140.

The oscillating circuit 250 generates an alternating current required for the

operation of the controller 280. Namely, the oscillating circuit 250 generates a current

having a specific frequency.

The display 260 shows vehicle condition data that makes the driver to perceive

the condition of the vehicle 110 at the outside of car. Vehicle condition data on the

display 260 comprises vehicle temperature, a battery voltage, an engine starting, and so

on. Also, selection data corresponding to the vehicle control signal from the remote

controller 120(e.g., remote starting, air conditioner starting, headlight on, and so on) and

operation result can be displayed on the display 280 under the control of the controller

280.

The RF transducer 270 receives the vehicle control signal from the remote

controller 120 to be sent to the controller 280, and transmits the operation result to the

remote controller 120 under the control of the controller 280.

The controller 280 controls the vehicle antenna 130 for communicating the

vehicle control signal and the operation result, and for displaying vehicle condition data

in response to the driver's command through the input device 220. In order to show

vehicle condition data on the display 260, the controller 280 can receive data relating to

the vehicle condition from the main unit 140 or the sensor being coupled to the main unit 140 through the main unit interface 240, if necessary. Also, the controller 280

changes vehicle condition setup data in response to the vehicle control signal or the

change request from the input device 220, and sends changed vehicle condition setup

data to the main unit 140. Although it is not shown in FIG 2, the vehicle antenna 130 can further

comprise a storage device for storing changed vehicle condition setup data, and an

emergency and a driving history of the vehicle 110. For example, if the vehicle 110

locates where the emergency cannot be sent to the remote controller 120, corresponding

data can be sent to the remote controller 120 or displayed on the display 260 later. Also,

the driver can use the driving history stored in the storage device of the vehicle antenna

130 for an electrical carkeeping accounts book.

Also, the vehicle antenna 130 can further comprise a data converter for

converting the vehicle control signal from the remote controller 120, vehicle condition

data in response to the driver command or vehicle condition setup data into an effect

sound or a voice and a speaker for outputting the converted sound or voice.

FIG 3 and FIG 4 are flowcharts for showing the operation of vehicle antenna

according to the preferred embodiment of the present invention, and FIG. 5 is a front

view of the vehicle antenna of the preferred embodiment of the present invention. Referring to FIG. 3, at step 310, the vehicle antenna 130 starts its operation. The vehicle antenna 130 of the present invention performs the predetermined operations(e.g.,

antenna function, vehicle condition display function, carcall function, and so on) for

electrical power supplied from the vehicle or the self-containing battery.

At step 315, the vehicle antenna 130 determines whether or not a vehicle

condition setup or display command is inputted through the input device 220. If the

vehicle condition setup or display command is inputted, the vehicle antenna 130

performs the vehicle condition setup or display operation at step 320 and then goes back

to step 315.

The way to display data relating to vehicle condition setup data on the display

260 when the driver inputs the vehicle condition setup or display command is shown in

FIG 5. Of course, the following description is only example of the vehicle antenna 130

according to the present invention.

Referring to the front view of vehicle antenna 130 shown in FIG 5, the vehicle

antenna 130 comprises the input device 220, the carcall sensitivity controller of carcall

detector 230 and the display 260.

The display 260 is for showing vehicle condition data to the driver by using

plural icons, numbers and images. Plural icons can be displayed on the display 260: a

carcall function operation icon 410, a vehicle impact detection icon 415, a driver call

icon 420, a sound output icon 425 when receiving the vehicle control signal, a function

halt display icon 430, an engine starting state maintenance icon 435, an auto door lock icon 440, an auto door lock/unlock icon 445, a number displaying region 450, an engine

starting state displaying region 455, a remaining battery displaying region 460, a vehicle

setup change region 465, and so on. The driver can check the function that he or she

selects through the icons, images on the display 260. On the number displaying region 450, the time after starting engine, the time

after turning engine off, the temperature inside of the car, and so on are displayed.

On the engine starting state displaying region 455, the operating state of engine

is displayed through the motion of road image.

On the remaining battery displaying region 460, the battery voltage of the

vehicle 110 that is measured by a voltage sensor being connected to the main unit 140 is

displayed.

The input device 220 comprises plural key buttons and each button is assigned

to operate independent function. With the plural buttons, the driver can change the mode

into an option setup mode(i.e., setup change mode of the main unit 140), and confirm

the vehicle condition and driving time.

When the driver presses the first button, the vehicle temperature measured by a

temperature sensor coupled to the main unit 140 is displayed on the number displaying

region 450. The vehicle temperature can be displayed in ^°C or °F according to the

driver's selection. When the driver presses the second button, a backlight of the display 260 can be turned on. Of course, after the predetermined time passed, the backlight will be

turned off automatically.

When the driver presses the third button, the mode of vehicle antenna 130 is

changed into a mode for changing the vehicle condition setup. In this mode, the driver

can change the option after selecting with the first and the second buttons. Also, when

the driver presses the fourth button after finishing the vehicle condition setup, then

changed vehicle condition data is sent to the main unit and the mode of vehicle antenna

130 is changed back to the receiving mode.

Referring to FIG 3 again, at step 325, the vehicle antenna 130 determines

whether data(e.g., vehicle control signal, operation result data, and so on) comes from

the remote controller 120 or the main unit. If receiving data, the vehicle antenna 130

goes to step 330;if not, to step 360(FIG 4).

At step 330, the vehicle antenna 130 determines whether or not received data is

a remote control signal(i.e., the vehicle control signal from the remote controller 120).

In case of remote control signal, the vehicle antenna 130 examines that the code number

of the remote controller 120, which is received together with the remote control signal,

is valid. If invalid, the vehicle antenna 130 returns to step 315. If valid, the vehicle

antenna 130 analyzes the received remote control signal and updates vehicle condition

setup data to be displayed on the display 260. Since the way of updating vehicle

condition setup data by the vehicle antenna 130 in response to the remote control signal is very similar to the way of updating in response to the driver command from the input

device 220, description about this procedure will be omitted.

At step 345, the vehicle antenna 130 sends updated vehicle condition setup data

corresponding to the remote control signal from the remote controller 120 to the main

unit 140. Then, the vehicle antenna returns to step 315 or terminates the process.

Referring to step 330 again, if received data is not a remote control signal(i.e.,

operation result data from the main unit 140, a driver call, and so on), the vehicle

antenna 130 goes to step 340.

At step 340, the vehicle antenna 130 analyzes received data and displays the

result. At step 345, the vehicle antenna 130 determines whether or not it is needed to

transmit data at step 325. If it is needed to transmit data, the vehicle antenna 130

transmits data at step 355. The vehicle antenna 130 returns to step 315 or terminates the

process.

Referring to FIG 4, at step 360, the vehicle antenna 130 determines whether or

not the carcall function has to be performed. For example, after the car is parked or the

engine is stopped, the vehicle antenna 130 can perform the antenna function and the

carcall function simultaneously.

In case of performing the carcall function, the vehicle antenna 130(i.e., the

carcall detector 230 of vehicle antenna 130) detects an abnormal sign(e.g., impact,

vibration, and so on) occurring on the vehicle at step 365. If there is no abnormal sign, the vehicle antenna 130 goes to step 360(or step 315);otherwise, performs the carcall

function(e.g., alarm sound, driver call, and so on) at step 370. Then, the vehicle antenna

130 returns to step 360(or step 315) or terminates the process.

On the other side, if the carcall function is not performed, the vehicle antenna

130 determines whether or not any operation command for other functions(e.g.,

backlight, reset driving time, and so on) is inputted. If operation command for other

functions is inputted, then the vehicle antenna goes to step 380 and performs that

function. Then the vehicle antenna 130 returns to step 315 or terminates the process.

FIG 6 is a block diagram of the vehicle antenna according to another

embodiment of the present invention, and FIG 7 is a front view of the vehicle antenna

according to another object of the present invention.

The vehicle antenna 130 can be installed on the predetermined location at the

inside of vehicle(e.g., upper part of dash board) or at the outside of car(e.g., A-pillar).

Namely, if the driver can see vehicle condition data displayed on the display 260 of

vehicle antenna 130, it does not matter on where the vehicle antenna 130 is installed.

But, if the vehicle antenna 130 is installed on the outside of vehicle, anyone

may push the button of input device 220 carelessly. Thus, it is needed to cover the

button of input device 220 so that the driver only operates the button. Referring to FIG. 6 and FIG. 7, the vehicle antenna 130 of the present invention comprises the power supply 210, the input device 220, the carcall detector 230, the main

unit interface 240, the oscillating circuit 250, the display 260, the RF transducer 270,

the controller 280 and a driver identifying device 510.

The driver identifying device 510 comprises a fingerprint input part 610, a

fingerprint identifying part(not shown), and a button cover 620. As shown in FIG. 7, the

button cover 620 can temporarily cover the buttons of input device 220 and the carcall

sensitivity controller. The way of inputting the driver's fingerprint is well known in the

art, detailed description will be omitted here.

The fingerprint identifying part compares the fingerprint inputted through the

fingerprint input device 610 with the predetermined fingerprint of driver stored on the

storage(not shown). If these two fingerprints coincide with each other, then fingerprint

identifying part sends coincidence data to the controller 280, and the controller 280

opens the button cover 620 to expose the buttons of input device 220.

Of course, if the vehicle antenna 130 is installed at the outside of vehicle, the

vehicle antenna 130 must be waterproof.

The accompanying drawings and the detailed description is only exemplary for

explaining the present invention in detail, not for limiting the scope of the present

invention as is claimed. Thus, it is apparent to those who skilled in the art that various

changes and equivalent embodiments can be made. The true scope of present invention

must be determined by accompanying claims. Industrial applicability

As aforementioned, the present invention can provide convenience to the driver

when changing the function setup of the main unit and checking vehicle data.

Also, since any module that was connected to the main unit can be connected to

the vehicle antenna in the present invention, cost for installation can be reduced and

more purchase effect can be expected.
