Mode for the Invention
[44] The preferred embodiment of the present invention, an in- vehicle wireless communication apparatus and a vehicle control system equipped with sensors, shall be described in detail with reference to the accompanying drawings.
[45] Fig. 1 is a drawing showing a vehicle installed with a wireless communication apparatus according to an embodiment of the present invention, and Fig. 2 is a drawing showing an exterior view of a wireless communication apparatus according to an embodiment of the present invention, and Fig. 3 is an electrical block diagram of a vehicle control system according to an embodiment of the present invention, and Fig. 4 is an electrical block diagram of a wireless communication apparatus according to an embodiment of the present invention, and Fig. 5 is an electrical block diagram of a mobile wireless transceiver according to an embodiment of the present invention.
[46] As shown in Fig. 1, a wireless communication apparatus 100 of the present invention can be attached to an A pillar or to a windshield 10 near a sun visor using a double- sided tape, etc.
[47] As shown in Fig. 2, electrical parts are internally mounted in a housing 115 of a wireless communication apparatus 100.
[48] Besides, in a housing 115, an antenna 110 is mounted on the outer surface, and a motion sensor 130 and a owner-call sensor 125 is mounted internally or on the outer surface. Wherein a motion sensor 130, used for detecting a movement of an object, can be realized using a pyroelectric infrared (PIR) sensor which detects infrared rays emitted from an ultrasonic sensor or a human body, etc. And, an owner-call sensor 125 is used for detecting a physical impact. In other words, an owner-call sensor 125 detects knockings by someone on an adjacent area of a windshield 10 where a wireless communication apparatus 100 is attached, and can be realized using a pressure sensor, etc.
[49] As shown in Fig. 3, a vehicle control system of the present invention is comprised of a mobile wireless transceiver 200 transmitting a radio frequency signal converted from a key signal generated by a user's key manipulation, and receiving a radio frequency signal transmitted by a wireless communication apparatus 100, a vehicle control apparatus 300 controlling a vehicle by a radio frequency signal transmitted by said mobile wireless transceiver 200, and a wireless communication apparatus 100 receiving a radio frequency signal from a mobile wireless transceiver 200, converting it into a vehicle control signal, transferring it to a vehicle control apparatus 300, converting detection signals received from the sensors 145, 155 into the radio signals, and transmitting them to a mobile wireless transceiver 200.
[50] Herein, a vehicle control apparatus 200 is connected to a terminal box 400 furnished in a vehicle. And, such a terminal box 400 is connected to an ECU 500 and a power supply unit 600 providing power charged in a car battery 610. Hence, a vehicle control apparatus 200 controls an ECU 500 using a signal from a mobile wireless transceiver 200 that is broadcasted by a wireless communication apparatus 100. In conclusion, an ECU 500 opens and closes door by controlling door open-close unit 520, or starts engine by controlling engine driving unit 530, or opens trunk by controlling a trunk lock release unit 540 by user's remote control.
[51] Next, as shown in Fig. 4, a detailed configuration of a wireless communication apparatus 100 of above described configuration can be comprised of or includes an antenna 110, and a RF transceiver 200 transmitting and receiving radio frequency signals to and from a mobile wireless transceiver 200 via said antenna 110, a motion sensor 130 detecting a movement of an object, a owner-call sensor 125 detecting a physical impact, a signal terminal 170 and a power supply terminal 165 for connection to a vehicle control apparatus 300, and a signal processing unit 150 converting a motion and impact detection signal received from said motion sensor 130 and owner- call sensor 125 into a radio frequency signal as an output to said RF transceiver 140, and receiving a radio frequency signal received by said RF transceiver 140 for a conversion into a vehicle control signal as an output to said signal terminal 170, and a power supply unit 160 providing power supplied via a power supply terminal 165 to a RF transceiver 140, a motion sensor 130, a owner-call sensor 125, and a signal processing unit 150.
[52] Herein, an antenna 110 is mounted on the exterior surface of a housing 115. Besides, a RF transceiver 140, a signal processing unit 150, and a power supply unit 160 are mounted inside of a housing 115. A motion sensor 130 and owner-call sensor 125 are mounted internally or on the exterior surface of a housing 115.
[53] Furthermore, it is recommended that a signal processing unit 150 transfers impact detection and a motion detection signal to a vehicle control apparatus 300 via a signal terminal 170. Then, a vehicle control apparatus 300 controls a vehicle by impact detection signal and the motion detection signal transferred from the wireless communication apparatus 100. In other words, a vehicle control apparatus 300 orders an ECU 500 to generate an alarm sound when a motion detection signal is received from a wireless communication apparatus 100. Then, the ECU 500 generates an alarm sound by controlling an alarm sound generation unit 510. Besides, a vehicle control apparatus 300 orders an ECU 500 to inform the person, who knocked, of an owner-call when impact detection signal is received. Then, the ECU 500 makes the left and right turn signal lights to blink for a couple of seconds.
[54] Furthermore, a RF transceiver 140 periodically generates and transmits a radio frequency signal to a mobile wireless transceiver 200. At this point, periodical transmission of a radio frequency signal is to inform the owner of the fact that there is no problem with the vehicle, in other words, there is no external impact or intrusion.
[55] Next, as shown in Fig. 5, a detailed configuration of a mobile transceiver 200 of the present invention can be comprised of or includes a wireless communication apparatus 100 and a RF transceiver 220 transmitting and receiving a radio frequency signal, a door- lock button 231, a door-lock release button 232, a trunk lock release button 233, a key input unit 230 generating a key signal in response to a manipulation of an engine start button 234, an alarm sound generation unit 250 and a display unit 240 informing an owner-call and a vehicle condition such as an intrusion, etc., and a control unit 210 for an overall control of a mobile transceiver 200.
[56] Moreover, a mobile transceiver 200, in other words, a control unit 210 controls an alarm sound generation unit 250 generating an alarm sound when a radio signal is not received for a predetermined period of time from a wireless communication apparatus 100. That is, a mobile transceiver 200 issues an alarm in response to the information transmitted by the wireless communication apparatus 100 indicating the presence of an owner-call or an intrusion. An alarm can be issued also when a periodical signal which is used to indicate the presence of a problem with the vehicle is not received.
[57] Next, a vehicle control apparatus 300 collects information, for an example, whether a vehicle is operating or not, from an ECU 500. Then, it is recommended that the vehicle control apparatus 300 turns on and off the power to the wireless communication apparatus 100 automatically based on the collected vehicle information since there is no need to drive the wireless communication apparatus 100 while the vehicle is operating. On the contrary, power is supplied to a wireless communication apparatus 100 when the engine of the vehicle is turned off and the vehicle is in a door-lock state.
[58] A in- vehicle wireless communication apparatus and a vehicle control system of the present invention is not limited to the exemplary embodiments described above, but it can be further implemented with various modifications without departing from the technical spirit and the scope of the present invention.
