  In these devices, basically, it is necessary to continuously turn on a power source for a sensor that detects an intruding object to continuously drive (operate), and there is a problem that power consumption (current consumption) is large.

  The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a drive control device for an in-vehicle device that can reduce power consumption.

  According to the first aspect of the present invention, the sensor intermittent drive means intermittently drives the proximity sensor for detecting an object approaching the vehicle. When the proximity sensor is intermittently driven by the sensor intermittent drive means, the in-vehicle device drive control means detects the object approaching the vehicle by the proximity sensor, and the in-vehicle equipment of the drive control target that has been stopped until then. Start driving. In this case, the proximity sensor is used in addition to the in-vehicle device to be driven and controlled, but since it is driven intermittently, its power consumption is small. In addition, the on-vehicle device to be controlled by driving is stopped until an object approaching the vehicle is detected, and driving is started when an object approaching the vehicle is detected, so that power consumption is small.

  In the first aspect of the present invention, even if the in-vehicle device is an intrusion sensor for detecting an object that has entered the passenger compartment as in the second aspect, as in the third aspect, It may be an in-vehicle communication device that communicates with a key communication device provided in a key.

  According to a fourth aspect of the present invention, in the in-vehicle device drive control device according to any one of the first to third aspects, the in-vehicle device drive control means detects an object approaching the vehicle by the proximity sensor. In the intermittent driving of the proximity sensor by the sensor intermittent driving means, when the object approaching the vehicle is not detected by the proximity sensor, it has a function of stopping the driving of the in-vehicle device that has been driven so far. The driving can be stopped.

  According to a fifth aspect of the present invention, in the in-vehicle device drive control device according to the fourth aspect, the in-vehicle device drive control means starts driving the in-vehicle device by detecting an object approaching the vehicle by the proximity sensor. If the vehicle-mounted device has a function for continuously driving the vehicle-mounted device during a period from when it stops detecting an object approaching the vehicle, the vehicle-mounted device can be driven appropriately.

  As described in claim 6, in the on-vehicle device drive control apparatus according to any one of claims 1 to 5, the sensor intermittent drive means detects the object approaching the vehicle by the proximity sensor, and the proximity sensor With the function to lengthen the drive stop period when driving the sensor intermittently, the approach sensor will consume less power in situations where the approaching object appears continuously and the detection state continues Can do.

  As described in claim 7, in the in-vehicle device drive control apparatus according to any one of claims 1 to 5, the proximity sensor receives a reflected wave with respect to the emitted signal and extracts a Doppler component. The sensor intermittent drive means has a function of extending the drive stop period when intermittently driving the proximity sensor as the speed of the object approaching the vehicle based on the Doppler component of the Doppler type proximity sensor is slower. Then, power consumption can be reduced.

  As described in claim 8, in the in-vehicle device drive control apparatus according to any one of claims 1 to 7, the proximity sensor receives a reflected wave with respect to the emitted signal and extracts a Doppler component. The vehicle-mounted device drive control means approaches the vehicle as the speed of the object approaching the vehicle based on the Doppler component increases when the Doppler proximity sensor is intermittently driven by the sensor intermittent drive means. If the vehicle has a function of widening the area for starting the driving of the in-vehicle device accompanying the detection of the object to be detected, the object approaching the vehicle can be detected more reliably.

  Here, as described in claim 9, in the in-vehicle device drive control apparatus according to claim 8, the in-vehicle device drive control means has a Doppler approach to widen an area for starting the in-vehicle device. When the amplitude of the Doppler component in the sensor is larger than the threshold value, it is preferable to have a function of setting a low threshold value when starting driving of the in-vehicle device accompanying detection of an object approaching the vehicle.

  According to the tenth aspect of the present invention, in addition to the function and effect of the on-vehicle device drive control device according to any one of the first to ninth aspects, the oscillation frequency changing means receives the reflected wave with respect to the emitted signal. Then, the oscillation frequency of the signal emitted from the Doppler proximity sensor that extracts the Doppler component is changed in a direction in which the amplitude of the Doppler component in the Doppler proximity sensor does not decrease. Therefore, it is possible to reduce the influence of disturbance (noise) when receiving the reflected wave.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
In this embodiment, the present invention is applied to a vehicle antitheft device. The vehicle antitheft device includes an intrusion sensor for detecting an object that has entered the vehicle interior. The intrusion sensor is an in-vehicle device (electric device) that is driven by power supply. The drive control device for the in-vehicle device in the present embodiment is a device for supplying power to the intrusion sensor to drive it.

  As shown in FIG. 1, a proximity sensor 20 is mounted on the vehicle 1 in addition to the intrusion sensor 10. The intrusion sensor 10 includes a radio wave transmitter / receiver 11 and a transmission / reception antenna 12 and detects an object that has entered the vehicle interior (an intruding object into the vehicle). The proximity sensor 20 includes a radio wave transmitter / receiver 21 and a transmission / reception antenna 22, and detects an approaching object outside the vehicle, that is, an object approaching the vehicle 1.

  In FIG. 2, the detection area Z1 of the intrusion sensor 10 and the detection area Z2 of the proximity sensor 20 are shown. The detection area Z1 of the intrusion sensor 10 is a vehicle interior. Further, the detection area Z2 of the proximity sensor 20 is an area from the vehicle outer surface including the passenger compartment to a predetermined distance L1. The predetermined distance L1 is about 3 m.

FIG. 3 shows an electrical configuration of the drive control device for the in-vehicle device in the present embodiment. Each member (electric equipment) shown in FIG. 3 is mounted on a vehicle.
In FIG. 3, the transmitter / receiver 21 of the proximity sensor 20 includes an oscillator 23, a receiver 24, and a mixer 25. The proximity sensor 20 (transmitter / receiver 21) is driven by power supply. By this driving, radio waves are output from the oscillator 23 via the antenna 22a, and an oscillation signal (electric signal) corresponding to the radio waves is sent to the mixer 25. Further, the reflected wave is received by the receiver 24 via the antenna 22 b by driving the proximity sensor 20, and a reception signal (electric signal) corresponding to the received radio wave is sent from the receiver 24 to the mixer 25. The mixer 25 mixes the signal from the oscillator 23 and the signal from the receiver 24 and sends it out as a Doppler signal. As described above, the proximity sensor 20 is a Doppler sensor that receives a reflected wave with respect to the emitted signal (radio wave) and extracts a Doppler component.

  The transceiver 11 of the intrusion sensor 10 includes an oscillator 13 and a receiver 14. The intrusion sensor 10 (transmitter / receiver 11) is driven by power supply. By this driving, the oscillator 13 transmits a radio wave via the antenna 12a, and the reflected wave is received by the receiver 14 via the antenna 12b.

  The proximity sensor 20 (the oscillator 23 and the receiver 24) is connected to the battery (vehicle power source) 30 via the switch 31. The intrusion sensor 10 (the oscillator 13 and the receiver 14) is connected to the battery 30 via the switch 32.

  The controller 40 includes a microcomputer and a signal processing circuit, and the controller 40 controls the switches 31 and 32 to control on / off of the power sources of the sensors 10 and 20. Further, the controller 40 inputs the Doppler signal from the mixer 25. Further, the controller 40 inputs a signal from the receiver 14 of the intrusion sensor 10. A security ECU 50 is connected to the controller 40. The security ECU 50 can communicate with the center (base station) by an in-vehicle wireless device.

  In this embodiment, the switch 31 and the controller 40 constitute a sensor intermittent drive means, and the switch 32 and the controller 40 constitute an in-vehicle device drive control means.

Next, the operation of the drive control device for on-vehicle equipment in the present embodiment will be described.
FIG. 4 shows the on / off state of the power supply of the proximity sensor 20, the sensing content (detection / non-detection) based on the output signal of the proximity sensor 20, the on / off state of the power supply of the intrusion sensor 10, and sensing based on the output signal of the intrusion sensor 10. It is a time chart which shows the content (detection / non-detection).

First, when a vehicle owner (a legitimate vehicle owner) locks the door and leaves the vehicle, the drive control device (vehicle anti-theft device) of the vehicle-mounted device is activated.
The controller 40 shuts off the power supply 32 by turning off the switch 32 that supplies power to the intrusion sensor 10. On the other hand, the controller 40 intermittently turns on the switch 31 that supplies power to the proximity sensor 20. That is, the drive stop period T1 and the drive period T2 are repeated in FIG. The drive stop period T1 is about 1 second to 1/10 second, and the drive period T2 is about several tenths of a second. Regarding the driving stop period T1, when the width of the detection area of the proximity sensor 20 (L1 value in FIG. 2) is 3 m, the speed of the object moving 3 m per second when T1 = 1 second is (3/1000). × 3600 = 10 km / h, and an object of 10 km / h or less can be detected.

  Then, an electric wave is emitted from the proximity sensor 20 in the driving period T2 in FIG. 4, and an object approaching the vehicle can be detected by receiving the reflected wave. Specifically, when the controller 40 receives the Doppler signal from the mixer 25 and the amplitude of the signal is greater than a predetermined value (threshold value), the controller 40 determines that an object approaching the vehicle has been detected. FIG. 4 shows a situation in which an object approaching the vehicle is detected at the timing t1.

  When the controller 40 detects an object approaching the vehicle, the controller 40 turns on the switch 32 that supplies power to the intrusion sensor 10 at the timing t2 in FIG. As a result, the intrusion sensor 10 is driven (activated) and the detection operation of the object that has entered the vehicle interior is started. That is, an object that has entered the vehicle compartment can be detected by transmitting a radio wave from the intrusion sensor 10 and receiving the reflected wave. Specifically, the controller 40 receives a signal from the receiver 14 and determines that an object has entered the vehicle when the level of the signal is greater than a predetermined value (threshold). FIG. 4 shows a situation in which an object is detected in the passenger compartment at the timing t3.

  When an object is detected in the passenger compartment, the controller 40 sends an intrusion detection signal to the security ECU 50. Thereby, the security ECU 50 notifies the center (base station) that the intruding object has been detected by the wireless device. By this communication, the center (base station) notifies the vehicle owner (authorized owner) to that effect.

  On the other hand, FIG. 4 shows a situation in which no object is detected inside the vehicle at the timing t4. Furthermore, it shows a situation in which an object approaching the vehicle is no longer detected at the subsequent timing t5. Then, the controller 40 turns off the switch 32 that supplies power to the intrusion sensor 10 at the timing of t6 in FIG. Thereby, the drive of the intrusion sensor 10 is stopped (the sensor 10 is stopped).

  As described above, in the vehicle antitheft device provided with the intrusion sensor 10 for detecting an object in the passenger compartment that is parked using radio waves, only the proximity sensor 20 that detects an approaching object outside the vehicle is normally stopped. It is possible to reduce current consumption by operating the intrusion sensor 10 continuously only when detecting an approaching object outside the vehicle by operating with an intermittent operation with a longer (rest time).

  That is, in consideration of the fact that the approaching object outside the vehicle stays in the detection area longer than the intruding object, the sensor 20 that detects the approaching object sets a longer stop time (pause time) and approaches the approaching object. The intrusion sensor 10 is controlled to be turned on using the object detection information, so that the current consumption as a whole can be reduced.

  More specifically, considering that an approaching person such as a suspicious person enters the detection area of the approach sensor 20 and arrives at the vehicle, it takes 1 second or more as described above. An approaching person can be sufficiently detected by repeating the operation of stopping (pause) for about 10 seconds and starting up for about several tenths of a second. On the other hand, since the period of intrusion into the vehicle interior may be short, when the intrusion sensor 10 is activated, it is continuously detected until it is stopped (paused).

  With the above-described operation, the intrusion sensor 10 that requires continuous operation can be stopped (rested) for a period other than a necessary period, and the proximity sensor 20 can be stopped (paused) for as long as possible. Is reduced.

As described above, according to the present embodiment, the following effects can be obtained.
(1) The proximity sensor 20 for detecting an object approaching the vehicle 1 is provided, and the proximity sensor 20 is intermittently driven by the switch 31 and the controller 40 constituting the sensor intermittent drive means. Further, when the proximity sensor 20 is intermittently driven by the switch 32 and the controller 40 constituting the in-vehicle device drive control means and the object approaching the vehicle 1 is detected by the proximity sensor 20, the driving is stopped until then. The driving of the intrusion sensor 10 to be driven is started. Therefore, although the proximity sensor 20 is used in addition to the intrusion sensor 10 (on-vehicle device subject to drive control), since it is driven intermittently, its power consumption is small. The intrusion sensor 10 stops driving until an object approaching the vehicle is detected, and driving is started when an object approaching the vehicle is detected, so that power consumption is small. As a result, power consumption can be reduced as compared to the case where the intrusion sensor 10 is always powered on and continuously driven (operated).

  (2) The switch 32 and the controller 40 constituting the on-vehicle device drive control means approach the vehicle 1 by the proximity sensor 20 when the proximity sensor 20 is intermittently driven after the proximity sensor 20 detects an object approaching the vehicle 1. When the detected object is no longer detected, the driving of the intrusion sensor 10 that has been driven is stopped. Therefore, the drive of the intrusion sensor 10 can be stopped appropriately.

  (3) The switch 32 and the controller 40 constituting the in-vehicle device drive control means detect an object approaching the vehicle 1 by the proximity sensor 20 to start driving the intrusion sensor 10 and then detect an object approaching the vehicle 1. The intrusion sensor 10 is continuously driven in a period until the driving of the intrusion sensor 10 is stopped due to the absence of detection. Therefore, it is possible to accurately detect the intruding object by appropriately driving the intrusion sensor 10.

For the intrusion sensor 10 and the proximity sensor 20, an ultrasonic sensor, an infrared sensor, an image sensor, or the like may be used.
Further, as a response when an intruder is detected by the intrusion sensor 10, an alarm sound may be output or a horn may be sounded.
(Second Embodiment)
Next, the second embodiment will be described focusing on the differences from the first embodiment.

As shown in FIG. 5, when the switch 31 and the controller 40 constituting the intermittent sensor driving means detect an object approaching the vehicle 1 by the proximity sensor 20, the drive stop period T1 when the proximity sensor 20 is intermittently driven. Lengthen. Specifically, in FIG. 5, the stop period in the intermittent drive is T1a until an object approaching the vehicle is detected. If an object approaching the vehicle is detected, the stop period in the intermittent drive is set to T1b ( > T1a). As a result, when the approaching object appears continuously and the detection state continues, for example, when the vehicle is stopped (parked) in a place where there is a lot of traffic, the power consumption of the proximity sensor 20 is further reduced. Can be reduced.
(Third embodiment)
Next, the third embodiment will be described with a focus on differences from the first embodiment.

  FIG. 6 is a flowchart showing processing executed by the controller 40. This process is started every predetermined time. The controller 40 takes in the Doppler signal in Step 100 of FIG. 6 and calculates the period T10 in the Doppler signal as shown in FIGS. 7A and 7B (Step 101 in FIG. 6). In 102, the drive stop period (time) T1 of the proximity sensor 20 is lengthened as the period T10 is longer, that is, as the moving speed v of the approaching object is slower.

  As described above, the proximity sensor 20 is a Doppler sensor that receives a reflected wave with respect to the emitted signal and extracts a Doppler component. The switch 31 and the controller 40 constituting the sensor intermittent drive means drive when the proximity sensor 20 is intermittently driven as the speed of the object approaching the vehicle 1 based on the Doppler component of the Doppler type proximity sensor 20 decreases. The stop period T1 is lengthened.

Thus, if the drive stop period T1 in the intermittent drive in the proximity sensor 20 is lengthened as the speed of the object is slower, the power consumption can be further reduced.
(Fourth embodiment)
Next, the fourth embodiment will be described with a focus on differences from the first embodiment.

  FIG. 8 is a flowchart showing processing executed by the controller 40. This process is started every predetermined time. The controller 40 takes in the Doppler signal in Step 200 of FIG. 8 and calculates the frequency and amplitude of the signal in Step 201. Further, the controller 40 determines a threshold value VT corresponding to the frequency in step 202. Specifically, the threshold value VT is set smaller as the frequency is higher.

  That is, when the period of the Doppler signal is short as shown in FIG. 9A and when the period of the Doppler signal is long as shown in FIG. 9B, the period is longer than the threshold value VT2 when the period is long. The threshold value VT1 is reduced when.

As shown in FIG. 10, lowering the threshold value VT means that the detection area is expanded, and the detection area of the proximity sensor 20 is increased as the speed of the object increases.
Thereafter, the controller 40 compares the amplitude of the signal with the threshold value VT in step 203 of FIG. 8, and when the amplitude of the signal is larger than the threshold value VT, the power source of the intrusion sensor 10 is turned on in step 204. On the other hand, if the amplitude of the signal is smaller than the threshold value VT in step 203, the controller 40 turns off the power supply of the intrusion sensor 10 in step 205.

As described above, the proximity sensor 20 is a Doppler sensor that receives a reflected wave with respect to the emitted signal and extracts a Doppler component. The switch 32 and the controller 40 constituting the in-vehicle device drive control means are configured such that when the Doppler type proximity sensor 20 is intermittently driven, the speed of the object approaching the vehicle 1 based on the Doppler component increases. The area for starting the driving of the intrusion sensor 10 accompanying detection of an object approaching 1 is widened. Therefore, the switch 32 and the controller 40 constituting the in-vehicle device drive control means allow the vehicle when the amplitude of the Doppler component in the Doppler type proximity sensor 20 is larger than the threshold value so as to widen the area where the intrusion sensor 10 starts to be driven. The threshold for starting driving the intrusion sensor 10 accompanying detection of an object approaching 1 is set low. Therefore, the faster the speed of an object approaching the vehicle, the lower the threshold value is set, and the detection area becomes wider, so that an object approaching the vehicle can be detected more reliably.
(Fifth embodiment)
Next, the fifth embodiment will be described focusing on the differences from the first embodiment.

  FIG. 11 is a flowchart showing processing executed by the controller 40. This process is started every predetermined time. The controller 40 takes in the Doppler signal from the proximity sensor 20 in Step 300 of FIG. 11, and calculates the amplitude W1 of the Doppler signal in Step 301. Further, in step 302, the controller 40 increases the oscillation frequency of the proximity sensor 20 by one step. Further, the controller 40 takes in the Doppler signal at this time in step 303, and calculates the amplitude W2 of the signal in step 304.

  Then, the controller 40 compares the amplitudes W1 and W2 of the signal at step 305, and if the amplitude W1 is larger than W2, the controller 40 maintains this oscillation frequency on the assumption that no radio wave as a noise component has been received. On the other hand, if the amplitude W1 is smaller than W2 in step 305, the controller 40 assumes that a radio wave as a noise component is received, and in step 306, lowers the oscillation frequency of the proximity sensor 20 by two steps.

  As described above, the controller 40 as the oscillation frequency changing means changes the oscillation frequency of the signal emitted from the Doppler proximity sensor 20 in a direction in which the amplitude of the Doppler component in the Doppler proximity sensor 20 does not decrease. As a result, it is possible to reduce the influence of disturbance (noise) when receiving the reflected wave.

Here, referring to the circuit configuration for changing the oscillation frequency, for example, the configuration shown in FIG. 12 may be employed.
In FIG. 12, a transistor 60, a resistor 61, a coil 62, and a variable capacitance diode 63 are used as an oscillator, and a variable power supply 65 is connected to the variable capacitance diode 63 via a coil 64. Then, the controller 40 controls the voltage value of the variable power source 65 to adjust the frequency of the transmitter. Specifically, the oscillation frequency can be increased by increasing the voltage, and the oscillation frequency can be decreased by decreasing the voltage.
(Sixth embodiment)
Next, a sixth embodiment will be described focusing on differences from the first to fifth embodiments.

  In each of the first to fifth embodiments, the in-vehicle device subject to drive control is the intrusion sensor 10, but in this embodiment, the in-vehicle device subject to drive control is a key-side communication device provided in the key. It is an in-vehicle communication device that communicates.

  As shown in FIG. 13, the in-vehicle communication device 70 can communicate with a key communication device (remote key) 71 by being driven by power supply. Furthermore, in addition to the vehicle-mounted communication device 70, the vehicle 1 is equipped with the proximity sensor 20 described above. The proximity sensor 20 is for detecting an object approaching the vehicle. As shown in FIG. 2, the detection area Z2 is a region from the outer surface of the vehicle including the passenger compartment to a predetermined distance L1.

  The proximity sensor 20 (the oscillator 23 and the receiver 24) is connected to the battery 30 of FIG. A vehicle-mounted communication device 70 is connected to the battery 30 via the switch 32. The controller 40 controls the switches 31 and 32. Further, the controller 40 inputs the Doppler signal from the mixer 25.

Next, the operation will be described.
14 shows the on / off state of the power supply of the proximity sensor 20, the sensing contents (detection / non-detection) based on the output signal of the proximity sensor 20, the on / off state of the power supply of the in-vehicle communication device 70, and the in-vehicle communication device 70. It is a time chart which shows unlocking operation | movement.

First, when the owner of the vehicle (the owner of the regular vehicle) locks the door and leaves the vehicle, the device is activated.
The controller 40 intermittently turns on the switch 31 that supplies power to the proximity sensor 20. That is, the drive stop period T1 and the drive period T2 are repeated in FIG. Then, in the driving period T2, a radio wave is emitted from the proximity sensor 20, and an object approaching the vehicle can be detected by receiving the reflected wave. Specifically, when the controller 40 receives the Doppler signal from the mixer 25 and the amplitude of the signal is greater than a predetermined value (threshold value), the controller 40 determines that an object approaching the vehicle has been detected. FIG. 14 shows a situation where an object approaching the vehicle is detected at timing t10.

  When the controller 40 detects an object approaching the vehicle, the controller 40 turns on the switch 32 that supplies power to the in-vehicle communication device 70 at the timing of t11 in FIG. As a result, the in-vehicle communication device 70 is driven and can communicate with the key communication device (remote key) 71. Thereafter, a door unlocking operation of the vehicle is executed using both the communication devices 70 and 71.

  In this embodiment as well, after the controller 40 detects an object approaching the vehicle 1 by the proximity sensor 20 (after t10 in FIG. 14), the controller 40 approaches the vehicle 1 by the proximity sensor 20 when the proximity sensor 20 is intermittently driven. When the detected object is no longer detected, the driving of the in-vehicle communication device 70 that has been driven is stopped. At this time, the controller 40 detects the object approaching the vehicle 1 by the proximity sensor 20 and starts the driving of the in-vehicle communication device 70 and then stops detecting the object approaching the vehicle 1. In the period until the driving of 70 is stopped, the in-vehicle communication device 70 is continuously driven (the switch 32 is continuously turned on).

  For the present embodiment, the methods described in the second, third, fourth, and fifth embodiments may be employed.
