In the figure, a body multiplexing ECU (electronic control unit) 10 as an operation control means controls various kinds of vehicle-related controls such as control of automatic lighting of headlights and meters of a vehicle, control of an air conditioner, control of a door lock, and the like. The microcomputer is supplied with detection signals from an illuminance sensor (not shown), a temperature sensor (not shown), and the like, and supplies a signal from a switch 13 operated when the driver inhibits smart entry. Is done. The door lock motor 14 is driven by the control of the ECU 10 to lock / unlock the door of the vehicle.

The transmitter 16 is provided in the vehicle,
On / off in accordance with the control from, a transmission request signal having a frequency of, for example, 2.45 GHz is generated and transmitted from the antenna 18 when on. The receiver 20 is provided in the vehicle,
For example, a return signal having a frequency of, for example, 300 MHz transmitted from the antenna 22 is received by the antenna 22, demodulated, and supplied to the ECU 10.

The portable unit 24 receives the transmission request signal from the transmitter 16 by the antenna 26, detects the signal by the detection unit 28, and supplies it to the transmission unit 30. The transmitting unit 30 has a stopping unit M1, and starts operating by the output of the detecting unit 28 or the turning on of the lock switch 32 or the unlock switch 34, and for example, returns a return signal obtained by modulating a carrier having a frequency of 300 MHz with a specific code. Generate and transmit from antenna.

FIG. 2 is a circuit diagram of a transmitter 16 according to an embodiment. In the figure, a control signal is supplied to a terminal 40 from the ECU 10. The control signal indicates that the high level is on and the low level is off. Terminal 40 is connected to the base of transistor 42, which is grounded via resonant element 44. The emitter of the transistor 42 is grounded via a capacitor C1 and a resistor R1, and the collector is connected to a power supply V1 via a load 43. A capacitor C0 is connected between the base and the emitter. The antenna 18 is connected to the collector of the transistor 42.

Here, when the control signal supplied to the terminal 40 is at a low level, the transmission is not performed because the transistor 42 is off. When the control signal is at a high level, the transistor 42 is turned on, and the output of the transistor 42 is oscillated at, for example, a frequency of 2.45 GHz by the resonance element 44 and transmitted from the antenna 18. FIG. 3 is a circuit diagram of the portable device 24 according to an embodiment. In the figure, a signal received by an antenna 26 is supplied to a detector 28, where a signal having a frequency of 2.45 G
Hz signal is detected. This detection output is amplified by the amplifier 52 in the transmission unit 30 and supplied to the ID generation unit 54. Here, the amplifier 52 outputs a high-level trigger signal when a signal having a frequency of 2.45 GHz is received, and the output of the amplifier 52 becomes low when no signal is received.

Each of the lock switch 32 and the unlock switch 34 is a normally open switch, and supplies a high-level signal from the DC power supply 50 to the ID generator 54 when pressed by the user. When a high-level trigger signal is supplied from the amplifying unit 52, the lock switch 32, or the unlock switch 34, the ID generation unit 54 serially reads the identification code stored in the built-in register, and outputs the bits k0 to k0. k2 is added and output. Here, bit k0 is set to 1 in the case of a trigger from the amplifying unit 52, and bit k2 in the case of a trigger from the lock switch 32.
Is set to 1, and in the case of a trigger from the unlock switch 34, the bit k1 is set to 1.

The identification code is data for specifying the portable unit 24, and includes the receiving unit 20 or the body multiplex ECU.

The local oscillator 78 generates a local oscillation signal having a frequency of about 300 MHz and supplies the signal to the mixer 76. The mixer 76 mixes the received signal and the local oscillation signal to obtain an intermediate frequency signal having a frequency of 455 kHz.

This intermediate frequency signal is supplied to a bandpass filter 8.
Unnecessary frequency components are removed at 0, and the amplitude is limited and amplified by a limiter amplifier 82, and then supplied to a detector 84. The detector 84 performs FM detection. The detection output is filtered by a low-pass filter 86 to remove unnecessary high-frequency components, and then compared with a reference level by a comparator 88 to be binarized.
As a result, the identification code transmitted from the portable device 24 is obtained, and is supplied from the terminal 90 to the body multiplexing ECU 10. Further, an RSSI (received signal electric field intensity) signal output from a limiter amplifier 82 as a monitoring means is digitized by an A / D converter 92 and supplied from a terminal 94 to the body multiplexing ECU 10.

FIG. 5 shows a flowchart of a first embodiment of the smart entry control process executed by the body multiplexing ECU 10. In the figure, the body multiplex ECU 10 executes step S1.

In step S28, the RSSI value supplied this time from the limiter amplifier 82 of the
It is determined whether the value is equal to or greater than the SI value or the RSSI value supplied this time is equal to or greater than a predetermined value. If this is satisfied, the process proceeds to step S20, and if not, the process proceeds to step S26. In step S26, the counter N is incremented by one, and thereafter, in step S29, it is determined whether or not the counter N exceeds a predetermined value K. Here, if N ≦ K, the process proceeds to step S20. If N> K, step S30

You. Also, after the unlock control, a transmission request is made at predetermined time intervals, and even if the identification code and the additional bit k0 match, if the RSSI value is equal to or less than the predetermined value or equal to or less than the previous value, the portable device moves away from the vehicle. The counter N is incremented assuming that it is approaching, and the counter N is incremented when the identification code and the additional bit k0 do not match. During this time, if the counter N is less than the predetermined value, the lock control is not performed. As a result, when the counter N becomes equal to or more than the predetermined value, the user separates from the vehicle, and performs the locking control of the door lock for security assuming that the user does not intend to get on the vehicle.

If the identification codes do not match in the above determination,
After waiting for a predetermined time in step S44, the process proceeds to step S40. If the identification codes match, in step S46, the additional bit k0 matches 1, and it is determined whether or not the entry is a smart entry. Here, if the additional bit k0 is not 1, the process proceeds to step S56. If the additional bit k0 is 1 and the entry is a smart entry, the door lock motor 14 is driven in step S48 to unlock the door. Thereafter, a predetermined value (for example, 30 seconds) is set in the prohibition timer in step S50, and during this time, transmission of the transmission request signal is stopped.

Next, in step S52, it is determined whether or not the door of the vehicle has been opened. If the door has been opened by the occupant, the process is terminated. If the door cannot be opened, the portable device 2 received by the receiver 20 in step S54
It is determined whether the identification code of No. 4 matches the identification code stored in the body multiplex ECU 10 in advance. This is for detecting a return signal transmitted from the portable device 24 by operating the lock switch 32 or the unlock switch 34. If the identification codes do not match in this determination,
Proceed to step S60. If the identification codes match, in step S56, the door lock motor 14 is driven according to the value of each of the additional bits k1 and k2 to unlock or lock the door lock. Here, when the additional bit k1 is 1, unlocking is performed, and when the additional bit k2 is 1, locking is performed.

Thereafter, in step S58, a predetermined value (for example, 30 seconds) is set in the prohibition timer. During this period, transmission of the transmission request signal is stopped. Then, in step S60, a specified time of, for example, several tens seconds elapses. If the specified time has not elapsed, it is determined in step S62 whether or not the door of the vehicle has been opened. If the door has been opened by the occupant, this process ends. If the door cannot be opened, the process proceeds to step S54. Step S60
If the specified time has elapsed, the process proceeds to step S40. The above steps S50 and S58 correspond to transmission request stopping means.

As described above, after the door lock is unlocked or locked, the smart entry is prohibited for a specified time, and during this time, only when the lock switch 32 and the unlock switch 34 are operated by the user's will. The door lock is unlocked or locked to prevent chattering of the operation. Further, since the transmission request signal and the return signal of the smart entry are not transmitted within the specified time, power consumption can be reduced.

FIG. 7 shows a flowchart of a third embodiment of the smart entry control processing executed by the body multiplexing ECU 10. In the figure, the body multiplex ECU 10 executes a step S7.
At 0, the control signal is supplied to the transmitter 16 to transmit the transmission request signal. Thereafter, the identification code of the portable device 24 received by the receiver 20 in step S72 is
And whether the additional bit k0 coincides with 1 or not.

If the identification codes do not match in the above determination,
After waiting for a predetermined time in step S74, the process proceeds to step S70. If the identification code and the additional bit k0 match, the counter N is reset to 0 in step S76, and the door lock motor 14 is driven to unlock the door lock in step S78. Next, in step S80, it is determined whether or not the door of the vehicle has been opened, and if the door has been opened by the occupant, this process ends. If the door cannot be opened, after waiting for a predetermined time in step S81, a control signal is supplied to the transmitter 16 to transmit a transmission request signal in step S82. After that, the identification code of the portable device 24 received by the receiver 20 in step S84 is
It is determined whether or not it matches the identification code stored in advance in 10 and whether the additional bit k0 matches 1.

In the above determination, the identification code or the additional bit k
If 0 does not match, an automatic lock process is performed for a predetermined time in step S86, and the process proceeds to step S70. The automatic lock process is a process for driving the door lock motor 14 to lock the door lock for security, for example, when no return signal is received for 30 seconds after the unlock control in step S78.

If the identification code or the additional bit k0 matches in step S84, the counter N is incremented by 1 in step S88, and thereafter, in step S90, it is determined whether or not the counter N exceeds a predetermined value K. Here, if N <K, the process proceeds to step S80. If N ≧ K, the process proceeds to step S92, in which the transmission of the transmission request signal is stopped to enter the smart entry inhibition mode for inhibiting the smart entry, and the process is terminated. Step S92 above
Corresponds to the operation inhibition means.

The smart entry prohibition mode is released when the door lock is locked or unlocked by operating the lock switch 32 and the unlock switch 34, or when the door lock is locked or unlocked using a key. , This process is restarted. Thus, in a situation where the user is standing by the vehicle or waiting for the vehicle to be refueled or washed, the smart entry prohibition mode is set, and the unlocking / locking of the door lock by the smart entry is stopped. In addition, the occurrence of chattering in the operation is prevented, and the transmission of the transmission request signal and the transmission of the return signal are stopped, so that unnecessary power consumption can be prevented.

By the way, in step S92, the smart entry prohibition mode is entered, and the door lock is locked or unlocked to release it. Instead, in step S92, the transmission power of the transmission request signal is reduced and the transmission request signal is reduced. The reachable area is reduced from the normal area I shown in FIG.
II (transmission area reduction means) and lock or unlock the door to return the transmission power of the transmission request signal to the normal area I (transmission area expansion means)
You may comprise so that it may be. Also in this case, in a situation where the user is standing by the vehicle or waiting for the vehicle to be refueled or washed, the transmission of the return signal is stopped to enter the reduced area II, and the door by the smart entry is stopped. Unlocking / locking of the lock is stopped to prevent chattering of the operation. At the same time, the transmission power of the transmission request signal is reduced, and power consumption can be reduced.

Although the present embodiment has been described on the premise of the most practical smart entry system, the present invention can be applied to various remote control systems (for example, a wireless engine starter) mounted on a vehicle. Applicable.
Needless to say, the present invention can be applied to ships and other moving objects.
