Description

  The present invention relates to a security device for a retrofit vehicle that is retrofitted to a vehicle.

  In recent years, with an increase in the number of thefts of vehicles such as automobiles, the number of users who retrofit various vehicle security devices to vehicles has increased. As such a retrofit vehicle security device, for example, the following configuration is known. That is, as shown in FIG. 4, the vehicle 50 is equipped with a remote key system 51. The remote key system 51 includes a wireless receiver 53 that performs mutual authentication with a remote key (transmitter) 52 carried by the user, and a door based on locking / unlocking information (lock signal / unlock signal) from the wireless receiver 53. A body ECU 55 that locks or unlocks the door by driving the lock motor 54 is provided.

  On the premise of such a vehicle configuration, a retrofit vehicle security device 61 is connected between the wireless receiver 53 and the body ECU 55. The retrofit vehicle security device 61 includes a retrofit controller 62, and a door courtesy switch 63, a door lock position switch 64, a bonnet switch 65, a trunk switch 66, and an ignition key switch (IGSW) 67 are provided on the input side of the retrofit controller 62. Are connected to each other. The door courtesy switch 63 detects the open / closed state of the door. The door lock position switch 64 detects the door locking / unlocking state. The bonnet switch 65 detects the open / closed state of the bonnet. The trunk switch 66 detects the open / closed state of the trunk. The ignition key switch 67 detects whether or not the ignition key is inserted into the key cylinder.

  On the other hand, a security indicator 68 is connected to the output side of the retrofit controller 62. The security indicator 68 includes a plurality (three in FIG. 4) of light emitting diodes (hereinafter referred to as “LED 68a”) and a resistor 68b connected in series to each of the light emitting diodes.

  An unlock signal including an ID code or a lock signal is output from the remote key 52 by a user operation. These lock signal and unlock signal are received by the wireless receiver 53 on the vehicle side. The wireless receiver 53 outputs a lock signal and an unlock signal to the body ECU 55. The body ECU collates the ID code stored in advance with the ID code included in each of the lock signal and the unlock signal, and when the two match, the body ECU drives and controls the door lock motor 54 to lock or unlock the door. .

  The retrofit controller 62 monitors the presence or absence of a lock signal and an unlock signal. When a lock signal output from the wireless receiver 53 to the body ECU 55 is detected, the retrofit controller 62 causes each LED 68a to blink, for example, at a constant cycle or blink so as to flow (warning mode). Thereby, the fact that the vehicle is in some alert is appealed to the outside, and crime prevention is improved. When the open state of any one of the door, the bonnet, and the trunk is detected in the security set state, the retrofit controller 62 blinks each LED 68a, for example, at a cycle shorter than that in the warning mode or increases the flow speed ( Threatening mode). The threatening display of each LED 68a threatens a third party other than the user. On the other hand, when an unlock signal output from the wireless receiver 53 to the body ECU 55 is detected, the retrofit controller 62 turns off the LEDs 68a.

  However, the conventional retrofit vehicle security device has the following problems. That is, for the purpose of reducing the wiring in the vehicle 50, a serial communication method (multiplex communication or multiplex) is often adopted for communication between various computers and various terminal devices in the vehicle 11. In many cases, the communication between the wireless receiver 53 and the body ECU 55 is also a serial communication method. However, the serial signal output from the wireless receiver 53 to the body ECU 55 has a different signal format for each manufacturer and even for the same manufacturer. For this reason, the retrofitting vehicle security device 61 (more precisely, the retrofitting controller 62) needs to be provided for each manufacturer and vehicle type having different signal formats, making it difficult to generalize the retrofitting controller.

  Further, the retrofit controller 62 needs to capture signals from, for example, a door courtesy switch 63, a door lock position switch 64, a bonnet switch 65, a trunk switch 66, and an ignition key switch 67 in order to monitor the state of each part of the vehicle. For this reason, when the retrofitting vehicle security device 61 is retrofitted to the vehicle 50, there is a problem that wiring connection work to each part of the vehicle 50 becomes complicated, and various signal processes in the retrofit controller 62 become complicated.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a retrofit vehicle security device that can be generalized without complicating the configuration.

  The invention according to claim 1 detects the lock / unlock state of the opening / closing part of the vehicle, and the first operation display means that is preinstalled in the vehicle and at least visually appeals to display that the vehicle is in a warning state. Locking / unlocking detecting means, and when the locking / unlocking detecting means detects the locking state of the opening / closing part, an operation start signal that is the power for operating the first operating display means is output to the first operating display means A security device for a retrofit vehicle that is retrofitted to a vehicle equipped with a first control means for operating the first action display means, and is capable of displaying at least a visual indication that the vehicle is in a warning state Second operation display means different from the first operation display means, and the first control means for operating the second operation display means when an operation start signal to the first operation display means is detected. Is another And summarized in that and a second controller.

According to a second aspect of the present invention, in the first aspect of the present invention, the vehicle further includes an abnormality detection unit that detects a vehicle abnormality assumed in advance, and the first operation display unit and the second operation display unit. includes a warning mode for displaying that the vehicle is being vigilant appealing to least visually respectively, also a threat mode menacing displayed in a manner different from that of the warning mode, the first control means, When the locking state of the opening / closing part is detected by the locking / unlocking detecting unit, the first operation display unit is set to a warning mode and a vehicle abnormality is detected by the abnormality detecting unit in the state set to the warning mode. The first operation display means is set to a threatening mode, and the second control means detects that the first operation display means is set to a warning mode. The gist of the present invention is that the second operation display means is set to the alert mode and the second operation display means is set to the threat mode by detecting that the first operation display means is set to the threat mode. To do.

  According to a third aspect of the present invention, there is provided communication means for performing mutual authentication with a portable device having a communication function, and a first display state indicating mutual authentication between the communication means and the portable device. The first operation display means capable of adopting a second display state indicating that the authentication is not established, and when the mutual authentication between the communication means and the portable device is established, the engine is allowed to start and the first operation is performed. First control means for controlling the display of the first operation display means from the second display state to the first display state by outputting an operation start signal which is the power for operation of the first operation display means to the display means; A retrofit vehicle security device retrofitted to a vehicle equipped with a second operation display means capable of displaying at least a visual indication that the vehicle is in a warning state, and an operation start to the first operation display means When a signal is detected The first control means for operating the second actuating display means to subject matter that and a separate second control means.

The invention according to claim 4 is the invention according to any one of claims 1 to 3 , wherein the first operation display means and the second operation display means each include one or more indicator lamps. The gist is that the number of indicator lamps constituting the second operation display means is larger than that of the indicator lamps constituting the first operation display means.

(Function)
According to the first aspect of the present invention, the retrofit vehicle security device outputs an operation start signal from the first control means to the first operation display means when the locking state of the opening / closing part is detected by the locking / unlocking detecting means. As a result, the first operation display means operates and is retrofitted to a vehicle that displays at least a visual indication that the vehicle is in a warning state. In this retrofit vehicle security device, the second control means detects the presence or absence of the operation start signal, and when the operation start signal is detected by the second control means, the second control means displays the second operation indication. Operate means. The second operation display means displays the fact that the vehicle is in a warning state together with the first operation display means by appealing at least visually. In addition to the first operation display means mounted on the vehicle in advance, the second operation display means also displays that the vehicle is in a warning state. For this reason, the alert state of the vehicle can be more actively appealed to the outside.

  Here, the operation start signal output from the first control means to the first operation display means is the operation power of the first operation display means, and the signal format of the operation start signal is basically between manufacturers and between vehicle types. There is no difference and it is common. It is not encoded (encoded) into a predetermined signal format. Further, when the first operation display means is operated, some signal (for example, electric power such as current and voltage) is output from the first control means to the first operation display means, and when the first operation display means is not operated, the first control means. No signal is output from the first operation display means. It is unlikely that the relationship between the presence / absence of signal output to the first operation display means and the operation of the first operation display means is reversed between manufacturers and vehicle types. For example, when the first operation display means is operated, no signal is output from the first control means to the first operation display means. When the first operation display means is not operated, any signal is sent from the first control means to the first operation display means. Is unlikely to be adopted. As described above, when the first operation display means is operated, the output pattern (cycle) of the signal may be different, but also in the point that some signal (for example, current, voltage) is output, between manufacturers and vehicle types. It is common among them.

  Under such a premise, in the retrofit vehicle security device according to claim 1 of the present application, a common operation start signal is output between the manufacturer and the vehicle type, which is output from the first control means to the first operation display means mounted on the vehicle standard. The second control means determines the presence or absence of the operation of the first operation display means based on the presence or absence, and operates the second operation display means based on the determination result. By inputting a common signal between manufacturers and vehicle types that is output to the first operation display means mounted on the vehicle as a standard, the connection configuration and signal processing of each part of the vehicle when retrofitting the vehicle security device to the vehicle is performed. Simplification is achieved. This is because it is not necessary to directly capture information relating to the state of each part of the vehicle, such as the locking / unlocking state of the opening / closing part of the vehicle, into the second control means. Therefore, the retrofit vehicle security device can be retrofitted to the vehicle regardless of the manufacturer and vehicle type and without complicating the configuration. In other words, the retrofit vehicle security device can be generalized regardless of the simple configuration, and can be retrofitted regardless of the manufacturer and vehicle type.

  According to the invention described in claim 2, in addition to the operation of the invention described in claim 1, when the locking state of the opening / closing part is detected by the locking / unlocking detecting means, the first operation display means is set to the warning mode. Is done. When the warning mode is set, the first operation display means displays at least a visual indication that the vehicle is on alert. When an abnormality of the vehicle is detected by the abnormality detection means in the state set in the warning mode, the first operation display means is set from the warning mode to the threatening mode. When the threatening mode is set, the first operation display means displays threatening in a display manner different from that in the warning mode by appealing at least visually.

  On the other hand, in the retrofit vehicle security device, when it is detected that the first operation display means is set in the warning mode, the second operation display means is set in the warning mode. The second operation display means displays at least visually that the vehicle is on alert together with the first operation display means. Further, when it is detected that the first operation display means is set to the threatening mode, the second operation display means is set to the threatening mode. The second operation display means appeals at least visually and displays a threat with the first operation display.

  In this way, the second operation display unit is operated in conjunction with the operation of the first operation display unit mounted in advance in the vehicle by taking the drive start signal from the first control unit to the first operation display unit. Can do. Further, in addition to the first operation display means mounted on the vehicle in advance, display indicating that the vehicle is in a warning state and threatening display are also performed by the second operation display means. For this reason, the alert state of the vehicle can be more actively appealed to the outside, and the threatening effect to the outside can be enhanced.

  According to the invention described in claim 3, when the mutual authentication between the communication means and the portable device is established, the retrofit vehicle security device is allowed to start the engine and is driven to the first operation display means. By outputting a start signal, the first operation display means is retrofitted to a vehicle that controls display from the second display state to the first display state. Incidentally, the first display state indicates that mutual authentication is established between the communication means and the portable device, and the second display state indicates that mutual authentication is not established between the communication means and the portable device. In this retrofitted vehicle security device, when the operation start signal to the first operation display means is detected, the second operation display means operates, and the second operation display means appeals at least visually and the vehicle is in a warning state. A message is displayed.

  Here, the configuration described in claim 3 has the same premise as that of claim 1. That is, the operation start signal output from the first control means to the first operation display means is the operation power (current or voltage) of the first operation display means, and the signal format of the operation start signal is between manufacturers and vehicle types. There is no fundamental difference between them, and they are common and are not encoded (encoded) into a predetermined signal format.

  Under such a premise, in the retrofit vehicle security device according to claim 3, by inputting a common signal between the manufacturers and between the vehicle types that is output to the first operation display means mounted in advance in the vehicle, It is not necessary to take in information relating to the state of each part to the second control means. For this reason, simplification of the connection structure and signal processing to each part of a vehicle at the time of retrofitting the security device for retrofit vehicles to a vehicle is achieved. Therefore, the retrofit vehicle security device can be retrofitted to the vehicle regardless of the manufacturer and vehicle type and without complicating the configuration.

According to the invention described in claim 4, in addition to the operation of the invention described in any one of claims 1 to 3, the number of indicator lamps constituting the second operation display means is the first operation. More than the indicator lamps that constitute the display means. For this reason, the variation of the display mode of the second operation display means can be set more than that of the first operation display means. Accordingly, it is possible to more positively display that the vehicle is in a warning state by changing the display mode of the second operation display means in various ways.

  In general, equipment that is pre-installed in a vehicle (that is, equipment that is standard equipment on the vehicle) is often configured simply. For this reason, only the display by the first operation display means mounted in advance on the vehicle is plain, and depending on the installation location of the first operation display means, the display state of the first operation display means may be difficult to see. . In addition, since the display state of the first operation display means is difficult to visually recognize, there is a possibility that the degree of appeal of the alert state to the outside and the crime prevention property may be insufficient. Accordingly, a simple warning display by the first operation display means mounted in advance in the vehicle is not enough, and a vehicle security device having an operation display means different from the first operation display means is purchased and the vehicle is purchased. A user who is retrofitted to is also assumed.

Under such circumstances, it is particularly desired that the second operation display means attached to the vehicle can recognize at a glance from the outside that the vehicle is in some alert state. In this regard, according to the invention described in claim 4, since the display mode of the second operation display means can be changed variously, it is possible to more actively display that the vehicle is in a warning state. A user's satisfaction with security and a sense of security can be obtained, and for example, the psychological intimidation effect on a vehicle target can be further enhanced.

  According to the present invention, the retrofit vehicle security device can be generalized without complicating the configuration.

The ignition key switch 27e detects whether or not the remote key 20 is inserted into the key cylinder. As a result, it is possible to detect that an opening / closing part such as a door has been opened other than by a regular remote operation using the remote key 20.

  A door lock motor 28 is connected to the output side of the microcomputer 23 via a motor drive circuit 25. The door lock motor 28 is provided for each door of the vehicle 11 (only one is shown in FIG. 1). A standard security indicator 29 is connected to the output side of the microcomputer 23 via a display drive circuit 26. The standard security indicator 29 is installed in the vehicle 11 as a standard, and the standard security indicator 29 includes a single light emitting diode (hereinafter referred to as “LED 29a”) and a resistor 29b connected in series to the LED 29a. Yes.

  As shown in FIG. 2, the standard security indicator 29 is provided at the lower part of the instrument panel, for example. The standard security indicator 29 has two operation modes, a warning mode and a threatening mode, which will be described later. In the alert mode, the standard security indicator 29 visually displays that the vehicle 11 is in some alert state. In the threatening mode, the standard security indicator 29 visually appeals in a display mode different from that in the warning mode.

  The wireless receiver 21 receives locking / unlocking information of a predetermined frequency sent from the remote key 20 via an antenna (not shown) and sends a lock signal / unlock signal to the microcomputer 23. More specifically, a serial communication method is adopted as a communication method between the wireless receiver 21 and the microcomputer 23, and the wireless receiver 21 encodes locking / unlocking information from the remote key 20 into a predetermined signal format ( Encoded) and sent to the microcomputer 23. The microcomputer 23 decodes (decodes) the signal from the wireless receiver 21.

  The memory 24 includes a ROM (read only memory) (not shown) and a RAM (read / write only memory). The ROM stores in advance various data such as a vehicle-side ID code necessary for ID authentication and various control programs for comprehensively controlling each part of the vehicle.

The RAM is a data storage area, that is, a work area for the microcomputer 23 to execute various processes by developing a ROM control program.

  The motor drive circuit 25 outputs a drive current to the door lock motor 28 based on the lock signal and the unlock signal from the microcomputer 23. When the vehicle door 25 is locked (locked), the motor drive circuit 25 supplies the forward rotation current flowing in the lock direction indicated by the arrow in FIG. 1 to the door lock motor 28 and unlocks the door. In this case, a reverse current that flows in the unlocking direction indicated by the arrow shown in FIG.

  The display driving circuit 26 outputs an indicator activation signal S1 and an indicator stop signal S2 to the standard security indicator 29 based on the security set signal and the security unset signal from the microcomputer 23. The indicator activation signal S1 is operating power (current or voltage) for operating the standard security indicator 29.

  When the lock signal from the wireless receiver 21 is input, the microcomputer 23 drives and controls the motor drive circuit 25 so that a current in the lock direction flows through the door lock motor 28. At the same time, the microcomputer 23 outputs the indicator operation signal S1 to the display driving circuit 26 in accordance with a display control program stored in advance in a memory (more precisely, ROM), and sets the operation mode of the standard security indicator 29 to the warning mode. For example, the microcomputer 23 controls the display drive circuit 26 so that the standard security indicator 29 blinks at a predetermined cycle. Further, in the alert mode, when the microcomputer 23 detects that the door or other opening / closing part is opened by other than the regular remote operation by the remote key 20, the microcomputer 23 sets the operation mode of the standard security indicator 29 to the threatening mode. For example, the microcomputer 23 controls the display driving circuit 26 so that the blinking cycle of the standard security indicator 29 is shorter than that in the warning mode. When the unlock signal from the wireless receiver 21 is input / output, the microcomputer 23 drives and controls the motor drive circuit 25 so that a current in the unlock direction flows through the door lock motor 28. At the same time, the microcomputer 23 outputs an indicator stop signal S2 to the display drive circuit 26 and turns off the standard security indicator 29.

<Retrofitting vehicle security device>

  The retrofit security indicator 31 includes a plurality (three in the present embodiment) of light emitting diodes (hereinafter referred to as “LED 31a”) and a plurality (three in the present embodiment) of resistors 31b connected in series to the respective LEDs 31a. I have. The retrofit security indicator 31 has two operation modes, a warning mode and a threatening mode which will be described later. In the alert mode, the retrofit security indicator 31 visually displays that the vehicle 11 is in some alert state. In the threatening mode, the retrofitting security indicator 31 visually appeals in a display mode different from that in the warning mode.

  The retrofit controller 32 includes a microcomputer 33, a display drive circuit 34, and a memory 35. The input side of the microcomputer 33 is connected to a connection point between the display drive circuit 26 and the standard security indicator 29.

The RAM is a data storage area, that is, a work area for the microcomputer 33 to execute various processes by developing a ROM control program.

  The microcomputer 33 monitors the presence or absence of an indicator activation signal S1 and an indicator stop signal S2 from the display drive circuit 34 to the standard security indicator 29. When the microcomputer 33 detects the indicator activation signal S1, the microcomputer 33 outputs the indicator activation signal S1 ′ to the display drive circuit 34 in accordance with a display control program stored in advance in the memory 35 (exactly ROM), and the operation of the retrofitting security indicator 31. Set the mode to alert mode. For example, the microcomputer 33 controls the display drive circuit 34 so as to blink so that each LED 31a of the retrofit security indicator 31 flows.

  Further, in the warning mode, the microcomputer 33 changes the output pattern (cycle) of the indicator activation signal S1 to a different one from the output pattern of the indicator activation signal S1 in the warning mode. Detect the migration. Then, the microcomputer 33 sets the operation mode of the retrofit security indicator 31 to the threatening mode. For example, the microcomputer 33 controls the display drive circuit 34 so that the speed at which each LED 31a of the retrofit security indicator 31 flows is faster than in the alert mode. When the microcomputer 33 detects the indicator stop signal S2, the microcomputer 33 outputs the indicator stop signal S2 ′ to the display drive circuit 34, and turns off the LEDs 31a of the retrofit security indicator 31.

  In the present embodiment, the microcomputer 23 constitutes a first control means, and the standard security indicator 29 constitutes a first operation display means. The switch unit 27 constitutes an abnormality detection unit, and the door lock position switch 27b of the switch unit 27 constitutes an unlocking / unlocking detection unit. Further, the retrofit security indicator 31 constitutes a second operation display means, and the LED 29a of the standard security indicator 29 and the LED 31a of the retrofit security indicator 31 each constitute an indicator lamp. The microcomputer 33 constitutes second control means. The indicator activation signal S1 constitutes an operation start signal.

<Operation of Embodiment>
Next, the operation of the retrofit vehicle security device configured as described above will be described.
<When getting off; Warning mode>
When the user gets off the vehicle, the user pulls out the remote key 20 from the key cylinder for starting the engine, opens the door of the vehicle and goes out of the vehicle, and then performs a locking operation with the remote key 20. That is, when the user operates the lock / unlock button of the remote key 20, a lock signal including an ID code stored in advance in the remote key 20 is transmitted from the remote key 20. This lock signal is received by the wireless receiver 21 on the vehicle side, and the wireless receiver 21 outputs the lock signal to the microcomputer 23. The microcomputer 23 of the body ECU 22 compares the vehicle-side ID code stored in advance with the ID code on the remote key 20 side included in the lock signal. When the two match, the microcomputer 23 drives and controls the door lock motor 28. Lock the door.

  The microcomputer 33 recognizes that the user is getting out of the vehicle when three conditions are satisfied: the door is closed, the door is locked, and the remote key 20 is not inserted into the key cylinder. When any one of these three conditions is not satisfied, the microcomputer 33 does not recognize the user getting off.

  When the user gets out of the vehicle, the microcomputer 23 activates the standard security indicator 29. That is, the microcomputer 23 sets the operation mode of the standard security indicator 29 to the alert mode, and controls the display drive circuit 26 so that the LED 29a of the standard security indicator 29 blinks at a predetermined cycle (security set state). The flashing light appeals to the outside that the vehicle 11 is in some alert state, and crime prevention is improved.

  Here, the microcomputer 33 of the retrofit controller 32 monitors the presence or absence of an indicator operation signal S1 and an indicator stop signal S2 from the body ECU 22 to the standard security indicator 29. When the indicator activation signal S1 is detected, the microcomputer 33 operates the retrofit security indicator 31. The microcomputer 33 sets the operation mode of the retrofit security indicator 31 to a warning mode, and blinks each LED 31a of the retrofit security indicator 31 in a predetermined cycle or in a flowing manner. By flashing light or flowing light, it is more actively appealed to the outside that the vehicle is in a certain alert state, and the so-called look-out effect is further enhanced.

  The retrofit vehicle security device 13 is disposed, for example, at the top of the instrument panel, and is easier to see from outside the vehicle than the standard security indicator 29 disposed at the bottom of the instrument panel. Further, the number of LEDs 31a of the retrofit security indicator 31 is larger than that of the LEDs 29a of the standard security indicator 29, and the display mode is also flashy. For this reason, it is possible to recognize at a glance that the vehicle is in some alert state, and for example, the psychological effect on the on-vehicle aim is enhanced. Therefore, it contributes to prevention of vehicle theft and mischief, and crime prevention is further improved.

  Further, the user can recognize that the operation mode of the standard security indicator 29 and the retrofit security indicator 31 is the warning mode by visually recognizing the LED 29a of the standard security indicator 29 and each LED 31a of the retrofit security indicator 31.

<When getting off; threatening mode>
When the open state of any one of the door, bonnet, and trunk is detected in the state set in the above-described warning mode, and when the door is unlocked / locked by a device other than the regular remote key 20, the microcomputer 23 The operation mode of the standard security indicator 29 is switched from the warning mode to the threatening mode. Then, the microcomputer 23 causes the LED 29a of the standard security indicator 29 to blink at a cycle shorter than that in the alert mode. Thereby, for example, the on-vehicle aim is threatened and theft of the vehicle is suppressed.

  Further, the microcomputer 33 of the retrofit controller 32 detects that the standard security indicator 29 has shifted from the warning mode to the threatening mode based on the change in the output pattern (cycle) of the indicator operation signal S1. Then, the microcomputer 33 switches the operation mode of the retrofit security indicator 31 from the warning mode to the threatening mode. For example, the microcomputer 33 blinks each LED 31a at a cycle shorter than that in the warning mode or increases the speed of light flow.

  In this way, by incorporating the indicator operation signal S1 from the body ECU 22 (more precisely, the display drive circuit 26) to the standard security indicator 29, it is retrofitted in conjunction with the operation of the standard security indicator 29 mounted in the vehicle 11 in advance. Operating the security indicator 31 is realized. Further, in addition to the threat display by the standard security indicator 29 previously mounted on the vehicle 11, the threat display is also performed by the retrofit security indicator 31. For this reason, for example, the intimidating effect on the on-vehicle aim is further enhanced and greatly contributes to crime prevention. Further, the user can recognize that the operation mode of the standard security indicator 29 and the retrofit security indicator 31 is a threatening mode by visually recognizing the LED 29a of the standard security indicator 29 and each LED 31a of the retrofit security indicator 31. .

<When boarding>
When the user operates the locking / unlocking button of the remote key 20 during boarding or boarding, an unlock signal including an ID code stored in advance in the remote key 20 is transmitted from the remote key 20. The unlock signal is received by the vehicle-side wireless receiver 21, and the wireless receiver 21 outputs the unlock signal to the microcomputer 23. The microcomputer 23 of the body ECU 22 compares the ID code on the vehicle side stored in advance with the ID code on the remote key 20 side included in the lock signal. When the two match, the microcomputer 23 drives and controls the door lock motor 28. Unlock the door.

  At the same time, the microcomputer 23 outputs an indicator stop signal S2 to the display drive circuit 26 and turns off the standard security indicator 29. Here, the microcomputer 33 of the retrofit controller 32 monitors the presence or absence of an indicator operation signal S1 and an indicator stop signal S2 from the body ECU 22 to the standard security indicator 29. When the indicator stop signal S2 is detected, the microcomputer 33 stops the retrofit security indicator 31 (security unset state).

<About the installation state of the security device for retrofit vehicles>
Thus, in the vehicle 11 equipped with the standard security indicator 29 in advance (that is, at the time of factory shipment), it is detected whether the standard security indicator 29 is in the security set state or the security unset state. The retrofit security indicator 31 is operated based on the detection result. Further, it is detected whether the standard security indicator 29 is operating in a warning mode or a threatening mode, and the operation mode of the retrofit security indicator 31 is set between the warning mode and the threatening mode based on the detection result. I try to switch.

  Here, the indicator operation signal S1 output from the body ECU 22 (more precisely, the display drive circuit 26) to the standard security indicator 29 is operating power for operating the standard security indicator 29. For this reason, the signal format of the indicator operation signal S1 is not different between manufacturers and between vehicle types, and is common. It is not encoded (encoded) into a predetermined signal format. Further, when the standard security indicator 29 is operated, some signal (electric power such as current or voltage) is output from the body ECU 22 to the standard security indicator 29. When the standard security indicator 29 is not operated, no signal is output from the body ECU to the standard security indicator 29.

  It is unlikely that the relationship between the presence or absence of signal output to the standard security indicator 29 and the operation of the standard security indicator 29 is reversed between manufacturers and between vehicle types. For example, a configuration in which some signal is output from the body ECU 22 to the standard security indicator 29 when the standard security indicator 29 is operated, and some signal is output from the body ECU 22 to the standard security indicator 29 when the standard security indicator 29 is not operated. The nature is low. As described above, when the standard security indicator 29 is operated, the output pattern (cycle) of the indicator activation signal S1 may be different, but also in the point that some signal such as current and voltage is output between manufacturers and It is common among car models.

  Under these assumptions, the retrofit controller 32 (exactly, depending on the presence / absence of an indicator operation signal S1 (voltage and current) common between manufacturers and vehicle types output from the body ECU 22 to the standard security indicator 29 mounted on the vehicle as standard. The microcomputer 33) determines whether or not the first operation display means is operating. Based on the determination result, the retrofit controller 32 operates the retrofit security indicator 31.

  By inputting a common indicator operation signal S1 that is output to the standard security indicator 29 mounted on the vehicle between the manufacturers and between the vehicle types, a signal for grasping the state of each part of the vehicle 11, for example, a signal from the switch unit 27 is received. There is no need to capture directly. For this reason, simplification of the connection structure and signal processing to each part of the vehicle when retrofitting the vehicle security device 13 to the vehicle 11 is achieved. Therefore, the retrofit vehicle security device 13 can be retrofitted to the vehicle 11 without complicating the configuration regardless of the manufacturer and the vehicle type. In other words, the retrofit vehicle security device 13 can be generalized regardless of a simple configuration, and can be retrofitted regardless of the manufacturer and the vehicle type.

  The lock signal and the unlock signal output from the wireless receiver 21 to the body ECU 22 are taken into the retrofit controller 32 (more precisely, the microcomputer 33), and the retrofit security indicator 31 is operated based on the lock signal and the unlock signal. It is also possible to determine whether or not. However, the communication method between the wireless receiver 21 and the microcomputer 23 is a serial communication method, and the serial signal from the wireless receiver 21, that is, the lock signal and the unlock signal each have a predetermined signal format. Yes. The signal format of serial signals such as the lock signal and the unlock signal is often different for each manufacturer and for each vehicle type. For this reason, in order to control the operation of the retrofit security indicator 31 based on the lock signal and the unlock signal output from the wireless receiver 21 to the body ECU 22, a retrofit controller 32 having different specifications for each manufacturer and for each vehicle type is prepared. There is a need.

  On the other hand, in the present embodiment, the retrofit controller 32 (more precisely, the microcomputer 33) detects the state of the standard security indicator 29 by detecting the indicator operation signal S1 output from the body ECU 22 to the standard security indicator 29. Trying to figure out. Since the indicator operation signal S1 output from the body ECU 22 to the standard security indicator 29 is operating power (current or voltage) for operating the standard security indicator 29, it does not differ for each manufacturer and for each vehicle type. The indicator operation signal S1 can be said to be a common signal format regardless of the manufacturer and vehicle type. Although the output pattern of the indicator operation signal S1, that is, the cycle may be different for each manufacturer and each vehicle type, some signal (current or voltage) is output from the body ECU 22 to the standard security indicator 29 at the time of security setting. The fact that no signal is output at the time of setting is common regardless of the manufacturer and vehicle type. Therefore, it is not necessary to prepare retrofit controllers having different specifications corresponding to different signal formats for each manufacturer and for each vehicle type.

(Effect of embodiment)
Therefore, according to the present embodiment, the following effects can be obtained.
(1) When an indicator operation signal S1 from the body ECU 22 to the standard security indicator 29 is detected, the retrofit security indicator 31 is operated by the retrofit controller 32. The indicator activation signal S1 is operating power (current or voltage) for operating the standard security indicator 29. For this reason, the signal format of the indicator operation signal S1 is not different between manufacturers and between vehicle types, and is common. Therefore, it is not necessary to prepare the retrofit controller 32 having different specifications for each manufacturer and each vehicle type. Therefore, the retrofit controller 32 can be generalized, and the retrofit vehicle security device 13 can be generalized.

  (2) Further, since the indicator operation signal S1 is input from the body ECU 22 to the standard security indicator 29 of the vehicle standard equipment, connection to each part of the vehicle when the retrofitting vehicle security device 13 is retrofitted to the vehicle 11 is performed. The configuration and signal processing can be simplified. This is because, for example, signals from the door courtesy switch 27a, door lock position switch 27b, bonnet switch 27c, trunk switch 27d and ignition key switch 27e are directly transmitted to the retrofit controller 32 in order to grasp the state of each part of the vehicle 11. This is because there is no need to capture. This greatly contributes to cost reduction and versatility of the retrofit vehicle security device 13.

  (3) The retrofit controller 32 detects that the standard security indicator 29 is set in the alert mode, and sets the retrofit security indicator 31 in the alert mode. The retrofit controller 32 detects that the standard security indicator 29 is set to the threatening mode, and sets the second operation display means to the threatening mode. As described above, by taking the indicator operation signal S1 from the body ECU 22 to the standard security indicator 29, the retrofit security indicator 31 can be operated in conjunction with the operation of the standard security indicator 29 mounted in the vehicle 11 in advance. Further, in addition to a simple standard security indicator 29 mounted on the vehicle 11 in advance, a retrofit security indicator 31 also displays that the vehicle 11 is in some alert state and a threatening display. For this reason, the alert state of the vehicle 11 can be more strongly appealed to the outside, and the threatening effect to the outside can be enhanced.

  (4) The number of LEDs 31 a of the retrofit security indicator 31 is larger than the number of LEDs 29 a of the standard security indicator 29. For this reason, variations in the display mode of the retrofit security indicator 31 can be set more than that of the standard security indicator 29. Therefore, a so-called full-scale security indicator can be constructed. In addition, by changing the display mode of the retrofit security indicator 31, it is possible to more actively and effectively display the fact that the vehicle 11 is in a warning state and threaten the outside.

Second Embodiment
Next, a second embodiment of the present invention will be described. The present embodiment is different from the first embodiment in that a retrofit vehicle security device is attached to a vehicle equipped with an immobilizer system. Accordingly, the same reference numerals are given to the same member configurations as those in the first embodiment, and a duplicate description thereof is omitted.

  As shown in FIG. 3, the engine immobilizer system 41 includes a transponder 42 a that is built in the ignition key 42 and transmits an ID code, and an engine start control device 43 that is mounted on the vehicle 11. The engine start control device 43 includes a receiving device 44, an immobilizer ECU 45, and an engine ECU 46.

  The receiving device 44 reads the ID code on the side of the ignition key 42 inserted into the ignition key cylinder 44a by the antenna coil (transponder key coil) 44b built in the ignition key cylinder 44a, and sends it to the immobilizer ECU 45. The transponder 42a is a so-called transmitter that does not require a battery. When excited at a predetermined frequency by the magnetic field generated by the antenna coil 44b, the transponder 42a stores electrical energy, and the stored electrical energy stores the ID on the ignition key 42 side. The code is transmitted at a predetermined frequency.

  The immobilizer ECU 45 collates the ID code sent from the receiving device 44 with the vehicle-side ID code stored in advance in the immobilizer ECU 45 and sends the collation result to the engine ECU 46.

  The engine ECU 46 determines whether or not the engine can be started based on the collation result of the ID code sent from the immobilizer ECU 45. Further, the engine ECU 46 collates with the immobilizer ECU 45 and determines whether or not the engine can be started based on the collation result. The engine ECU 46 permits the engine to start when the ID code verification and the verification with the immobilizer ECU 45 are all established, and sets the engine start standby state (engine start standby state). When the ignition key 42 is operated in the engine start standby state, the engine ECU starts the engine.

  On the other hand, the engine ECU prohibits the engine start if either of the ID code verification and the immobilizer ECU verification fails. Even if the ignition key 42 is operated in this engine start prohibited state, the engine will not start. For this reason, the engine cannot be started when the ID code transmitted from the ignition key 42 cannot be read on the vehicle side and when the ID code on the ignition key 42 side does not match the ID code on the vehicle side. . Thereby, theft of a vehicle etc. are suppressed and crime prevention property is improved.

  An immobilizer indicator 47 that displays an operating state of the engine immobilizer system 41 is connected to the output side of the immobilizer ECU 45. The immobilizer indicator 47 is provided as a standard in the vehicle 11, and includes an LED 47a and a resistor 47b connected in series to the LED 47a. The immobilizer ECU 45 causes the LED 47a of the immobilizer indicator 47 to blink at a predetermined cycle by outputting an indicator operation signal S1 to the immobilizer indicator 47 when the engine start is prohibited (hereinafter referred to as “security set state”). The immobilizer ECU 45 outputs the indicator stop signal S2 to the immobilizer indicator 47 in the engine start standby state, thereby turning off the LED 47a of the immobilizer indicator 47 (hereinafter referred to as “security unset state”). The user can recognize whether or not the engine can be started by visually recognizing the immobilizer indicator 47.

  A retrofit vehicle security device 13 is connected to a connection point between the immobilizer ECU 45 and the immobilizer indicator 47. The microcomputer 33 of the retrofit vehicle security device 13 monitors the presence / absence of the indicator operation signal S1 and the indicator stop signal S2 output from the immobilizer ECU 45 to the immobilizer indicator 47. When the microcomputer 33 detects the indicator activation signal S1, it activates the retrofit security indicator 31. The microcomputer 33 blinks each LED 31a at a predetermined cycle in accordance with a display control program stored in advance in the memory 35 (more precisely, ROM). When the microcomputer 33 detects the indicator stop signal S2, the microcomputer 33 stops the retrofit security indicator 31.

  In the present embodiment, the display mode of the immobilizer indicator 47 in the security unset state constitutes a first display state, and the display mode of the immobilizer indicator 47 in the security set state constitutes a second display state. Further, the ignition key 42 constitutes a portable device, and the receiving device 44 constitutes a communication means. Further, the immobilizer ECU 45 and the engine ECU 46 constitute first control means, and the immobilizer indicator 47 constitutes first operation display means. The LED 47a constitutes an indicator lamp.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) The retrofit vehicle security device 13 is connected to a connection point between the immobilizer ECU 45 and the immobilizer indicator 47. When detecting the indicator operation signal S1 from the immobilizer ECU 45 to the immobilizer indicator 47, the microcomputer 33 activates the retrofit security indicator 31. Therefore, even if the vehicle 11 is not equipped with the standard security indicator 29 as described in the first embodiment, the retrofit security indicator 31 is utilized by using the indicator operation signal S1 from the immobilizer ECU 45 to the immobilizer indicator 47. Can be activated.

  The immobilizer indicator 47 flashes when the door is locked, and turns off when the door is unlocked. The immobilizer indicator 47 is similar in flashing and extinguishing timing to the standard security indicator 29 shown in the first embodiment. However, the immobilizer indicator 47 is configured to turn off when the proper ignition key 42 is inserted into the ignition key cylinder 44a and to blink when it is pulled out. For this reason, even if the immobilizer indicator 47 is opened or unlocked, for example, if the proper ignition key 42 is not inserted into the ignition key cylinder 44a, the immobilizer indicator 47 continues to blink.

  In this respect, the operation is slightly different from the standard security indicator 29 of the first embodiment. That is, the standard security indicator 29 is turned off immediately when the door is properly unlocked. On the other hand, the immobilizer indicator 47 is sufficiently practical in spite of a slight time difference from when the door is properly unlocked until the ignition key 42 is inserted into the ignition key cylinder 44a. For example, it does not make sense to detect a signal from a turn indicator (turn) and link a retrofitted security indicator 31 to it.

  (2) The indicator operation signal S1 output from the immobilizer ECU 45 to the immobilizer indicator 47 is operation power (current or voltage) for operating the immobilizer indicator 47. For this reason, the signal format of the indicator operation signal S1 is not different between manufacturers and between vehicle types, and is common. That is, when the immobilizer indicator is operated, some signal (that is, electric power such as current or voltage) is output from the immobilizer ECU to the immobilizer indicator. No signal is output. It is unlikely that the relationship between the presence / absence of signal output to the immobilizer indicator 47 and the operation of the immobilizer indicator 47 is reversed between manufacturers and vehicle types. For this reason, when the immobilizer indicator 47 is operated, the output pattern of the indicator activation signal S1, that is, the cycle or the like may be different, but some signal (power such as current or voltage) is output. It is common among manufacturers and between vehicle types.

  In this embodiment, the microcomputer 33 of the retrofit vehicle security device 13 operates the retrofit security indicator 31 depending on the presence / absence of the common indicator operation signal S1 output between the immobilizer ECU 45 to the immobilizer indicator 47 and between the manufacturers. I am doing so. By inputting a common signal that is output to the immobilizer indicator 47 between manufacturers and between vehicles, the door opening / closing state, door locking / unlocking state, whether the ignition key 42 is inserted into the ignition key cylinder 44a, etc. It is not necessary to directly capture the state of each vehicle part in the retrofit vehicle security device 13. For this reason, when retrofitting the security device for a retrofit vehicle 13 to the vehicle, the connection configuration between the security device for the retrofit vehicle 13 and each part of the vehicle and signal processing in the security device for the retrofit vehicle 13 are simplified. Therefore, the retrofit vehicle security device 13 can be retrofitted to the vehicle 11 without complicating the configuration regardless of the manufacturer and the vehicle type. In other words, the retrofit vehicle security device 13 can be generalized regardless of the simple configuration, and can be retrofitted regardless of the manufacturer and the vehicle type.

(Another embodiment)
In addition, you may implement both the said embodiment as follows.
-In 1st and 2nd embodiment, you may make it change the number of LED31a of the retrofit security indicator 31 arbitrarily. For example, two, four, five and more LEDs may be provided.

  In the first and second embodiments, all the LEDs 31a may be the same color, or may be a plurality of colors such as red and blue. When each LED 31a has a plurality of colors, variations in the display mode of the retrofit security indicator 31 can be increased compared to the case where all the LEDs 31a have the same color. Further, for example, by blinking a plurality of blue or red LEDs 31a so as to flow, it is possible to more effectively appeal that the vehicle 11 is in some alert state.

  In the first and second embodiments, an external notification device (not shown) may be provided in the retrofit vehicle security device 13. That is, when the standard security indicator 29 shifts from the warning mode to the threatening mode, the microcomputer 33 shifts the retrofitted security indicator 31 from the warning mode to the threatening mode, and in addition, the abnormality of the vehicle 11 via the external notification device. Inform the outside of the state. For example, the microcomputer 33 notifies the user's mobile phone registered in advance of the abnormal state of the vehicle 11 by voice or e-mail, or reports the abnormal state of the vehicle 11 to a pre-signed security company or the like.

  In the first and second embodiments, an auto alarm device may be mounted on the vehicle 11 so that the auto alarm device and the retrofit vehicle security device 13 are interlocked. This auto alarm device issues a warning with a horn or the like when an unauthorized entry into the vehicle compartment is detected. The automatic alarm device sets / unsets an alarm in conjunction with the electronic key system 12 so as not to generate an alarm at the time of ID authentication lock / unlock. That is, when the door is locked using the remote key 20, the auto alarm device enters an alarm set state (warning state), and when the door is unlocked using the remote key 20, it enters an alarm unset state (standby state). . For example, the auto alarm device detects a method other than remote operation using the remote key 20, that is, an act of opening the door without ID authentication as an unauthorized entry into the vehicle interior, and generates an alarm.

  In this case, the standard security indicator 29 and the retrofit security indicator 31 also display the operating state of the auto alarm device. That is, when the auto alarm device is in the alarm set state, the standard security indicator 29 and the retrofit security indicator 31 blink at predetermined intervals. In the alarm unset state, the standard security indicator 29 and the retrofit security indicator 31 are turned off. Thus, the standard security indicator 29 and the retrofit security indicator 31 can be operated in synchronization with the auto alarm device.

  In the first embodiment, the standard security indicator 29 and the retrofit security indicator 31 may be operated and stopped based on the presence / absence of a signal from the body ECU 22 to the door lock motor 28, respectively. The drive signal (current) output from the body ECU 22 to the door lock motor 28 is basically the same for each manufacturer and for each vehicle type. When the door lock motor 28 is driven, a common drive signal is output from the body ECU 22. By taking this common drive signal and controlling the operation of the standard security indicator 29 and the retrofit security indicator 31, the retrofit vehicle security device 13 can be retrofitted to the vehicle 11 regardless of the manufacturer and vehicle type. Sex is secured. However, in this case, a signal generation device (not shown) is provided between the connection point between the motor drive circuit 25 and the door lock motor 28 and the microcomputer 33 of the retrofit controller 32. This signal generator is composed of, for example, a single resistor or a plurality of resistors, and the motor drive current output from the motor drive circuit 25 to the door lock motor 28 is processed by the microcomputer 33 by passing through the resistor or resistors of the signal generator. The signal is converted into a signal having a predetermined voltage.

  ・ When the user carries the portable device and approaches the vehicle and enters the predetermined area of the vehicle, the door lock is automatically unlocked. Conversely, when the user leaves the vehicle and goes out of the predetermined area of the vehicle, the door is unlocked. The retrofitted vehicle security device 13 may be attached to a vehicle equipped with an electronic key system in which the lock is automatically locked.
