Specific implementation mode

The anti-theft device of the present invention can be embodied as playing the mode of anti-theft feature to individual vehicle and embody To cooperate to play the mode of anti-theft feature with the antitheft theft management center 21 being managed to more vehicles.Cause This, with two-wheeled motor vehicle (in the following description, otherwise referred to as vehicle) for object, by the former the case where is set as embodiment 1, the case where the latter, is set as embodiment 2 and embodiment 3, next coming in order illustrate.

[embodiment 1]

Substantially by ECU3, (engine control unit, engine start judge the anti-theft device 2 of the motorcycle 1 of present embodiment Unit) and anti-theft module 4 (anti-theft control unit, engine start judging unit) composition, ECU3 is as traveling power source The control of engine is such, related with the driving functions of motorcycle 1, and therefore, standard facility is in vehicle 1.

In this regard, anti-theft module 4 is used exclusively for antitheft device, therefore it is free use, only wants anti-theft feature User can independently select anti-theft module 4 when buying motorcycle 1.In addition, though the user's purchase for not needing anti-theft feature does not have The motorcycle 1 of anti-theft module 4, but in the case of going for anti-theft feature in use, also can monomer buy antitheft mould Block 4 is installed on the motorcycle 1 of oneself to add.

Therefore, ECU3 is configured to play the driving functions (profit of original motorcycle 1 under the specification of no anti-theft module 4 Realized with aftermentioned normal mode), under the specification for having anti-theft module 4 other than the driving functions of motorcycle 1, also with it is anti- 4 phase of module is stolen to coordinate to play anti-theft feature (realizing using aftermentioned anti-theft modes).

In addition, as the countermeasure illegally replaced for preventing ECU3 for the purpose of stealing vehicle 1, anti-theft module 4, in advance First assign intrinsic ID to ECU3 and anti-theft module 4 respectively.In the present embodiment, it is stored in ECU3 and anti-theft module 4 respectively Interior product information, such as sequence number, batch number, delivery destination information in any one product information as ID and by It is automatic to assign.These product informations are intrinsic, therefore, can be used as determining the ID of ECU3, anti-theft module 4, by This, can save the effort of special ID of the setting for carrying out ID certifications.But the setting of ID is not limited thereto, and can also be made With the special ID completely irrelevant with product information.

Then, by ECU3 and anti-theft module 4 be electrically connected it is initial when, mutual ID is associated, later, is being drawn Mutual ID is checked when holding up each startup, on this basis, ECU3 carrys out enforcement engine startup so that ID is consistent for condition. In addition, it is so-called be electrically connected it is initial when, refer to purchase when independently select anti-theft module 4 in the case of, refer in vehicle 1 Assembling procedure at the time of ECU3 is connected and is powered on anti-theft module 4, additional installation is antitheft in use Refer at the time of ECU4 is connected and is powered on anti-theft module 4 by user in the case of module 4.

Hereinafter, being illustrated to the concrete structure of ECU3 and anti-theft module 4 based on Fig. 1.

ECU3 by ID authentication departments 6, pattern switching portion 7, determination unit 8 could be started constitute.ID authentication departments 6 have following work( Energy：The intrinsic ID of the sides ECU3 as described above is assigned in advance, and the ID of its own and the ID of 4 side of anti-theft module are subjected to core It is right.Pattern switching portion 7 selectively executes the normal mode for the driving functions for only executing above-mentioned motorcycle 1 and in addition to traveling Any one pattern in anti-theft modes outside function also by the coordination with 4 side of anti-theft module to execute anti-theft feature.It could Start determination unit 8 carry out playing when engine start under anti-theft modes the checked result based on ID come to engine start permission or Forbid the function of being judged, only make allow judgement in the case of, so that the engine starting device 9 for being equipped on vehicle 1 is worked, To start engine.

In the case where vehicle 1 does not install anti-theft module 4 (state that ECU3 is not electrically connected with anti-theft module 4), The pattern switching portion 7 of ECU3 switches to normal mode side, could start determination unit 8 and switch to permission side, and maintain the switching shape State.Therefore, ECU3 only executes the driving functions of motorcycle 1 based on normal mode, also, at engine startup, without with The ID of 4 side of anti-theft module is checked, but engine starting device 9 is unconditionally made to work.Although motorcycle 1 does not have anti-as a result, Function is stolen, but engine start can be travelled as usual.

On the other hand, anti-theft module 4 is sentenced by the theft of ID authentication departments 10 including inclination sensor 11 and vibrating sensor 12 Determine the composition of portion 13.ID authentication departments 10 are with the following functions：Assign the intrinsic ID of anti-theft module 4 side in advance, and by its own The ID of the sides ID and ECU3 is checked.Theft determination unit 13 judges vehicle 1 whether there is or not theft occurs, when stealing, The theft inhibition processing for avoiding vehicle 1 from being pulled away is executed, will be described below about the processing.

Then, if the anti-theft module 4 with above structure by the assembling procedure of vehicle 1 or user in use It adding equipment and is electrically connected with the sides ECU3, then ID intercourses in the sides ECU3 and the ID authentication departments 6,10 of 4 side of anti-theft module, And it is registered respectively by the ID of other side side is with the ID of itself associated.After, it is necessary to allow to pass through sale based on user Dealer etc. come to control program rewrite, the registration content of the ID could be changed.If the association of ID is completed, The ID authentication departments 6 of the sides ECU3 export anti-theft modes switching command to pattern switching portion 7, pattern switching portion 7 based on the instruction come Anti-theft modes are switched to from normal mode.

In anti-theft modes, the ID authentication departments 6 of the sides ECU3 will be from the ID certifications of 4 side of anti-theft module when engine starts every time The ID and registration ID of itself that portion 10 inputs is checked, and in the case where ID is consistent, ID consistent informations are exported to could Start determination unit 8, in the case where ID is inconsistent, or in the case where not inputting ID from 4 side of anti-theft module (hereinafter, by institute There are these situations to be all expressed as the inconsistent situations of ID), the inconsistent information of ID is exported to could start determination unit 8.

Equally, after ID associations, the ID authentication departments 10 of 4 side of anti-theft module also will be from the sides ECU3 when engine starts every time ID authentication departments 6 input the ID and registration ID of itself checked, in the case where ID is consistent, by ID consistent informations export to Determination unit 8 could be started, in the case where ID is inconsistent, the inconsistent information of ID is exported to could start determination unit 8.

Here, as described above, in order to all unanimously be carried out to ID in the ID authentication departments 6,10 of 4 side of the sides ECU3 and anti-theft module Judgement, it is necessary to be respectively regular device, and must normal mounting pass through electric wiring (aftermentioned K-Line17) in vehicle 1 It interconnects.In the case where any one of ECU3 and anti-theft module 4 are by illegal replace, ID is inputted even if from other side side It is not regular ID, therefore, ID is inconsistent, will not be from right when removing any device 3,4 or electric wiring is cut off Square side inputs ID, and therefore, ID verifications itself can not carry out (hereinafter, all these situations are all expressed as illegally replacement etc.).

ECU3's could start determination unit 8 to input ID from the ID authentication departments 6,10 of 4 both sides of ECU3 and anti-theft module respectively Consistent information is condition, and switching to allows side.(either party or both sides are the inconsistent information of ID in the case of in addition to this In the case of), it determination unit 8 could be started switches to and forbid side, thus forbid engine start.In addition, when forbidding engine start, The loudspeaker 14 of vehicle 1, headlamp 15 can also be made to work simultaneously, it is abnormal to be notified to surrounding.

On the other hand, after being connected with the sides ECU3, the theft determination unit 13 of anti-theft module 4 starts to steal at inhibition Reason, the processing is continuously carried out when motorcycle 1 is in dead ship condition always.Using from inclination sensor 11 and vibrating sensor 12 detection information and loudspeaker 14 and headlamp 15, to execute theft inhibition processing.For example, make engine stop and incite somebody to action Motorcycle 1 in dead ship condition is loaded in taken away on truck etc. in the case of, when putting into truck motorcycle 1 inclination hair Changing, motorcycle 1 can be involved come ride during carrying using truck.

Therefore, in the case where detecting the variation at inclination angle using inclination sensor 11, or vibration biography is being utilized Sensor 12 and in the case of detecting ride, theft determination unit 13 makes the judgement stolen, and makes the loudspeaker of motorcycle 1 14 and headlamp 15 work.Exception is notified to surrounding, therefore, can cut down the criminal intent of offender to inhibit to steal as a result, Surreptitiously.

Moreover, as discussed above, the anti-theft device 2 of motorcycle 1 according to the present embodiment, by ECU3 with Anti-theft module 4 be electrically connected it is initial when, it is by respective ID authentication departments 6,10 that ID is interrelated and register, After, when engine starts every time, with the ID in respective ID authentication departments 6,10 unanimously for condition, determination unit 8 could be started Switching to allows side and enforcement engine startup.

In other words, the ID registrations of 4 side of the sides ECU3 and anti-theft module mean that it is just to be recognized connected other side side mutually Device is advised, the arbitrary side at engine startup in 4 side of the sides ECU3 and anti-theft module is determined as the inconsistent situations of ID later Under, the arbitrary side can be considered as and removed for the purpose of stealing vehicle, or carried out illegally more by regular device It changes, or the mutual electric wiring of connection is cut off.Moreover, in the case where ID is inconsistent, determination unit 8 could be started and remained Forbid that side is constant and forbids to engine start, therefore, motorcycle 1 can be prevented by offender drives and is pulled away vehicle It steals in possible trouble.

It wants it is emphasized that carrying out being mutually authenticated this point to mutual ID between ECU3 and anti-theft module 4.That is, such as The prior art described in " technical problems to be solved by the invention " unilaterally carries out core from 4 side of anti-theft module to the ID of ECU3 like that To in the case of, the illegal replacement etc. of anti-theft module 4 can not be identified in the sides ECU3, so as to cause illegal engine start It is allowed to, but by being mutually authenticated, needless to say the illegal of ECU3 is replaced, also can to the illegal replacement of anti-theft module 4 In the sides ECU3 by reliable recognition.Even if as a result, in the feelings for carrying out illegal replacement etc. to any one in ECU3 and anti-theft module 4 Under condition, also vehicle theft can be prevented by forbidding engine start.

In addition, like this in the present embodiment, the driving functions of motorcycle 1 are not only assigned to ECU3, it is also right in advance ECU3 assigns the anti-theft feature coordinated with anti-theft module 4.It will be advance specifically, being assigned to the ID authentication departments 6 of ECU3 The function that the ID of intrinsic ID and 4 side of anti-theft module of registration is checked, to pattern switching portion 7 assign with anti-theft module 4 into Row is coordinated to execute the function of anti-theft modes, is assigned at engine startup based on from ECU3 or anti-to that could start determination unit 8 The inconsistent information of ID of module 4 is stolen to forbid the function of engine start.

Therefore, the case where user of motorcycle 1 of no anti-theft module 4 wants anti-theft feature in use is being bought Under, if by the anti-theft module 4 individually bought addition be installed on the motorcycle 1 of oneself, can automatically by the ID of ECU3 with newly chase after The ID of the anti-theft module 4 added is associated to be registered mutually, to obtain the anti-theft feature based on ID certifications as described above. As a result, it is additional anti-theft module 4 is installed when, such as be not necessarily to completely to ECU3 for ID being associated/being registered etc. and antitheft The control program of module 4 is rewritten, therefore, without by motorcycle 1 with to sale dealer etc., thus can be very easily Additional installation anti-theft module 4.

In addition to this, present embodiment is characterized in that, is drawn like this to execute using the processing in the control of ECU3 Hold up forbidding for startup.That is, in this anti-theft device (for example, technology of patent document 1), it is electrical to engine start by cutting off Engine start is forbidden in the power supply of system, if but offender be laid with the cloth for leading to by other paths engine start electrical system Line can then simply allow engine start.

It in the present embodiment, can in order to start engine although the ID of 4 side of the sides ECU3 and anti-theft module is inconsistent No startup determination unit 8, which switches to, allows side, for that purpose it is necessary to rewrite the control program in ECU3, thus needs a large amount of effort.It should The fact helps to cut down the criminal intent of offender, is more reliably prevented from further increasing the safety of anti-theft device 2 Vehicle theft.

Therefore, ECU3 has OBD functions (On-Board Diagnostics：Self-diagnosing function), in each portion of vehicle 1 When point being abnormal, the alarm lamp (not shown) for the instrument board for being set to vehicle 1 is set to light, and will be corresponding with anomalous content Failure code is stored in ECU3.If by identifying that out of order user passes through vehicle 1 with extremely sale based on lighting for alarm lamp Quotient etc. is sold, then diagnostic tool to be connected to ECU3 carry out read failure code, implements fault diagnosis and places under repair accordingly.

In the present embodiment, K-Line is used as to the interface of ECU3, diagnostic tool (such as is equipped with diagnostic tool Laptop etc.) be connected to K-Line, for this reason, it may be necessary to which anti-theft module 4 is detached from the sides ECU3.However, ECU3 can not be single The ID solely completed between anti-theft module 4 is mutually authenticated, therefore, vehicle 1 be absorbed in the state that can not start engine and can not be into Row fault diagnosis.Therefore, a pair of connectors of K-Line is provided on ECU3 so that can be connected to by anti-theft module 4 In the state of ECU3, concurrently implement fault diagnosis using diagnostic tool.

Fig. 2 is the definition graph for indicating the connection status of anti-theft module 4 and diagnostic tool via K-Line with respect to ECU3.At this In example, the K-Line17 being extended from ECU3 is made to diverge a pair of connectors 18a, 18b of same specification is arranged.As a result, The connector 18a (the first connector) that anti-theft module 4 can be connected to a K-Line17 is motionless, and when carrying out fault diagnosis Another connector 18b (the second connector) is connected with diagnostic tool 19.It as a result, can be in failure diagnostic process according to need To start engine based on ID certifications, fault diagnosis can be implemented and repair without any problem.

In addition, the structure of connector 18a, 18b of K-Line17 is not limited to above structure.For example, it is also possible to such as Fig. 3 It is shown, 2 K-Line17 are set in ECU3, by each K-Line be connected on the shell of ECU3 set a pair of connectors 18a, 18b (the first connector, the second connector), even in this case, can also obtain same function and effect.

In addition, for example, as shown in figure 4, diagnostic tool 19 can also be connected to ECU3 with anti-theft module 4 via K-Line17. Specifically, the interface of 2 K-Line17 can be set in anti-theft module 4, an interface is connected to via K-Line17 ECU3, and another interface is connected to diagnostic tool 19 via K-Line17.It even in this case, also can be by antitheft mould Block 4 is connected constant with ECU3, and connects diagnostic tool 19 via the anti-theft module 4, therefore, can obtain same effect effect Fruit.

[embodiment 2]

Then, to the present invention is embodied as the embodiment 2 of the anti-theft device to cooperate with theft management center 21 2 It illustrates.

Fig. 5 is the overall structure figure of the anti-theft device 2 for the motorcycle 1 for indicating embodiment 2, and Fig. 6 is to indicate anti-theft module 4 The definition graph of connection status via K-Line17 with respect to ECU3.

First, if being illustrated to the structure of 1 side of vehicle based on Fig. 5, about ECU3 ID authentication departments 6 and could open Dynamic determination unit 8, structure is identical with embodiment 1, about pattern switching portion 7, be based on via aftermentioned 3G, 4G communication unit 23 and Anti-theft modes are switched to from the anti-theft modes switching command at theft management center 21.

ID authentication departments 10, theft determination unit 13 about anti-theft module 4, structure is identical as embodiment 1, including new GPS receiving unit 22 and 3G, 4G communication unit 23 (communication unit).GPS receiving unit 22 is come from using GPS antenna (not shown) to receive The location information data of GPS satellite is calculated/is obtained position (latitude, longitude, absolute altitude of this vehicle based on the location information data Deng) and output this to theft determination unit 13 and 3G, 4G communication unit 23.

3G, 4G communication unit 23, which has to receive and dispatch by the mobile phones circuit such as 3G, 4G between theft management center 21, to be believed The function of breath.Details will be described below, and being executed at any time using 3G, 4G communication unit 23 will be by GPS receiving unit 22 The detection information etc. of accessed this truck position information, inclination sensor 11 or vibrating sensor 12 is sent in theft management The transmission of the heart 21 handle and receive from theft management center 21 to the judgement result that is judged whether there is or not vehicle theft Reception is handled.

In addition, as shown in fig. 6, in the present embodiment, the single connector 18 of K-Line17 is provided on ECU3, It is connected with connector 18 instead of anti-theft module 4 from the sides ECU3 by diagnostic tool 19 when breaking down.Anti-theft module 4 is carried out Separation leads to that engine start can not be carried out in fault diagnosis, therefore, takes other countermeasures, this point will be retouched below It states.

Theft management center 21 is that the more vehicles 1 pre-registered in order to prevent occur theft and are set to predetermined region Base station judges vehicle whether there is or not theft occurs by mobile phone circuit, and there is a situation where steal to notify by vehicle To user etc..

It is registered with the ECU3 of each vehicle 1 and ID of anti-theft module 4 in the ID registers 24 at theft management center 21, and registers There is the ID (ID for being shown in figure single car) of the user of the vehicle 1.In addition, in order to be carried out to vehicle whether there is or not theft occurs Judgement, has theft determination unit 25 in theft management center 21, which plays the anti-theft module with each vehicle 1 The 13 identical function of theft determination unit having in 4 as described later preferentially holds the theft determination unit 13 of 4 side of anti-theft module Pirate steals inhibition processing.

Then, as described above, being registered with ECU3, anti-theft module 4, user in the ID registers 24 at theft management center 21 Each ID therefore its register step is described first.

Identical as embodiment 1, anti-theft module 4 is free use when buying motorcycle 1, can be to antitheft in purchase Module 4 is independently selected, and it is anti-can also to add installation in use after the motorcycle 1 for buying no anti-theft module 4 Steal module 4.

In order to what must be to determine to the user of the progress ID registrations of theft management center 21, purchase vehicle 1.Therefore, it is purchasing ID is registered to theft management center 21, Huo Zhe in moment recommended user in the case of buying the motorcycle 1 with anti-theft module 4 ID is registered to anti-theft pipe in moment recommended user in the case of adding installation anti-theft module 4 during using motorcycle 1 Reason center 21.In 1 side of vehicle at the moment, ECU3 has been carried out with anti-theft module 4 and is electrically connected, in each ID authentication departments 6,10 The middle ID by itself is with the ID of other side side associated to register.It is identical as embodiment 1, using be stored in respectively ECU3 and Product information is used as ID in anti-theft module 4.

If user will can determine that the information of vehicles of bought vehicle 1 using mobile phone according to the recommendation that ID is registered (such as Vehicle Identify Number) and the mail address of oneself are notified to theft management center 21, then are registered in the ID at theft management center 21 The ID of user is registered together with information of vehicles and mail address in portion 24.The ID of user at this time can be by theft management Unilateral decision is carried out at center 21, can also be set as the ID that user likes.

In addition to this, in the present embodiment, user when notifying information of vehicles and mail address, also force by notification engine The specific operation condition of startup steps on the ID that the specific operation condition is also registered together with the ID of user to theft management center 21 Note portion 24.So-called engine force start, refer in the state of no anti-theft module 4 (that is, not having ID certifications) performed by ECU3 Engine start, it is assumed that be connection of the diagnostic tool 19 to ECU3 in fault diagnosis.It is strong in order to make ECU3 execute the engine System starts, and user must carry out defined operation to vehicle 1, and the content of predetermined operation at this time is specific operation condition, to When theft management center 21 carries out ID registrations, the content of predetermined operation at this time can be arbitrarily decided in user.

For example, an example as specific operation condition, the standard-sized sheet operation that can enumerate throttle executes 5 within 5 seconds Secondary situation.Hope regardless of user can preset the intrinsic specific operation condition of vehicle, but except fault diagnosis When in addition usual, exist by the third party using some way reads specific operation condition and unlawfully carry out engine start can It can property.Specific operation condition is arbitrarily decided in user, so as to further increase safety related with specific operation condition.

In addition, switching to normal mode side in the pattern switching portion 7 of 1 side ECU3 of vehicle at the moment, judgement could be started Portion 8, which switches to, allows side, the theft determination unit 13 of anti-theft module 4 to be stopped.Although motorcycle 1 does not have antitheft work(as a result, Can, but in can as usual engine start come the state that travels.

If the ID registrations of user are completed, vehicle 1 is being determined according to information of vehicles in theft management center 21 On the basis of to the vehicle 1 send ID notice ask.ID notice requests are by 3G, 4G communication unit 23 of the anti-theft module 4 of 1 side of vehicle It is received, and is entered each ID authentication departments 6,10 of ECU3 and anti-theft module 4.Each ID authentication departments 6,10 by the ID of itself via 3G, 4G communication unit 23 returns back to theft management center 21, by these ID in the state of associated with the ID of registered user It registers to ID registers 24.

The theft determination unit 25 at theft management center 21 can be respective to the ECU3 and anti-theft module 4 that are equipped on vehicle 1 as a result, ID and possess the vehicle 1 user ID between correspondence be identified, later, stolen in corresponding vehicle 1 Deng in the case of, mail notification can be sent to the user of the vehicle 1.

If as described above, the ID registrations at theft management center 21 are completed, from theft management center 21 to corresponding vehicle 1 sends anti-theft modes switching command.The anti-theft modes switching command received via 3G, 4G communication unit 23 is inputted antitheft The theft determination unit 13 of module 4, and input the pattern switching portion 7 of ECU3.

Then, theft determination unit 13 started to work based on the anti-theft modes switching command, also, pattern switching portion 7 from Normal mode switches to anti-theft modes, could start determination unit 8 based on the checked result of ID to switch over.Vehicle 1 rises as a result, Function is prevented to the theft based on anti-theft modes, specifically, handled using theft determination unit 13 to start to steal inhibition, and And if the checked result based on ID at engine startup, determination unit 8 could be started and be considered as the illegal of ECU3 or anti-theft module 4 Replace etc., then forbid engine start.

Then, if like this registering each ID of ECU3, anti-theft module 4, user to the ID registrations at theft management center 21 Portion 24, then its ID registers content and persistently keeps without changing, and the ECU3 based on anti-theft modes switching command and antitheft The switching state of module 4 is also persistently kept.

In the present embodiment, be not only the control of 1 side of vehicle, in addition to the determination processing at theft management center 21 with Outside, theft inhibition processing performed in such anti-theft modes is also executed, is described in detail below.

First, theft inhibition processing performed in 1 docking process of vehicle is illustrated, in 1 side of vehicle and anti-theft pipe Under the situation that can be communicated between reason center 21, using the theft determination unit 25 of 21 side of theft management center preferentially to antitheft mould The theft determination unit 13 of 4 side of block executes theft inhibition processing.

Therefore, periodically (such as every 5 minutes) send theft inhibition processing institute from 1 side of vehicle to 21 side of theft management center The various information needed.Specifically, in the anti-theft module 4 of 1 side of vehicle, by inclination sensor 11 and vibrating sensor 12 Detection information is input to 3G, 4G communication unit 23 via anti-theft device 2, and will be by this parking stall confidence acquired in GPS receiving unit 22 Breath is input to 3G, 4G communication unit 23, these information are sent out together with ECU3 and the ID of anti-theft module 4 via 3G, 4G communication unit 23 It send to 21 side of theft management center.

In the theft determination unit 25 at theft management center 21, corresponding vehicle 1 is determined based on received ID, Theft inhibition processing is executed based on sensor detection information and this truck position information on this basis.First, to corresponding vehicle 1 Whether generation theft is judged, for the determination processing, in addition to the tilt variation of the motorcycle 1 described in embodiment 1, is shaken Other than dynamic detection, this truck position information is also utilized.Although for example, corresponding vehicle 1 engine stop but this truck position change, In this case, it is considered as illegal carrying motorcycle 1.There is no any omen stolen is implied, waited for Machine is until receive next information from 1 side of vehicle.

In addition, when there is the arbitrary omen stolen, it is likely to occur using theft determination unit 25 to make expression The interim judgement of theft.At this point, being read and the ID phases received by 1 side of vehicle from ID registers 24 using theft determination unit 25 Theft is confirmed that mail is sent to the mail address of the user by the ID of corresponding user.Receive the user that theft confirms mail To whether recognizing that the variations such as carrying of corresponding vehicle 1 are judged (whether be action that oneself is carried out), what is recognized In the case of reply without reply mail, in the case where being unaware that reply need should to mail and take to police carry out The measures such as notification.

In stealing determination unit 25, when receiving the mail without reply, cancel the interim judgement stolen, then Carry out standby until receiving information from 1 side of vehicle next time.When receiving the mail for needing to cope with, interim judgement is switched to With the formal judgement for determining the theft meaning, abnormal notification instruction and theft reply engine control instruction are sent to 1 side of vehicle. Via 3G, 4G communication unit 23 of anti-theft module 4, abnormal notification instruction is input to the theft determination unit 13 of anti-theft module 4, and will Theft copes with engine control instruction input to the engine control portion (not shown) of ECU3.

Abnormal notification instruction is measure identical with when being stolen described in embodiment 1, and robber is utilized based on the instruction Surreptitiously determination unit 13 makes loudspeaker 14 and headlamp 15 work, to carry out abnormal notice to surrounding.

In addition, utilizing the theft determination unit at theft management center 21 based on theft reply engine control program shown in Fig. 7 25 instruct to execute theft reply engine control.

In stealing determination unit 25, the control letter based on the ECU3 received from 1 side of vehicle via 3G, 4G communication unit 23 Breath is based on these information to grasp the transport condition of vehicle 1, the operating status of engine successively, according to the program of Fig. 7 come appropriate Switching is sent to the command content of the sides ECU3.

First, whether vehicle 1 is judged in dead ship condition in step sl.Has the detection work(of speed in ECU3 In the case of energy, the detection information is received by 21 side of theft management center, accordingly it is also possible to be executed based on speed The determination processing of step S1.It, can also will be by anti-theft module 4 in addition, in the case where ECU3 does not have the detection function of speed GPS receiving unit 22 acquired in this truck position information be sent to theft management center 21, and the variation based on its this truck position To execute the judgement of step S1.

When the judgement of step S1 be " being (affirmative) " when, be transferred to step S2 and to engine whether be in halted state into Row judgement.When being determined as "Yes", in step s3 engine start is forbidden sending as theft reply engine control instruction To 1 side of vehicle.Based on the instruction, the determination unit 8 that could start of ECU3 is switched to and forbids side in 1 side of vehicle, due to later Engine start is prohibited, therefore vehicle can not travel.

In addition, when step S2 is determined as " no (negative) ", it is transferred to step S4 and stops engine as theft reply Engine control instructs and is sent to 1 side of vehicle.Based on the instruction, stop fuel injection using the engine control portion of ECU3, with Engine is stopped.Then, when being again transferred to step S2, due to having made the judgement of "Yes", send in step s3 Engine start is forbidden, the engine start after 1 side of vehicle is forbidden.

In addition, when step S1 is determined as "No", it is transferred to step S5 and exports engine to reduce and draw as theft reply It holds up control instruction and is sent to 1 side of vehicle.Based on the instruction, using the engine control portion of ECU3 come the delay etc. of run time, So that engine output reduces.Thus be unable to maintain that the speed of practicability, therefore, offender can abandon continuing the thought of traveling and Vehicle 1 is set to stop.Therefore, the judgement that "Yes" is made when being again transferred to step S1 is stopped using the engine in step S4 It sends, so that engine is stopped in 1 side of vehicle, the transmission then forbidden using the engine start in step S3 forbids it in 1 side of vehicle Engine start afterwards.

If making engine stop in the driving process of vehicle 1, transport condition becomes unstable, is not only this vehicle, for week The vehicle 1 enclosed is also possible to impact, but due to only limiting in the process of moving speed, this can be prevented The case where sample, is in possible trouble.Moreover, promoting to stop by reducing speed in the driving process of vehicle 1, engine stops if parking Only, if engine stop if after startup be prohibited.As a result, offender for the means that can use of theft vehicle gradually by To limitation, therefore, the criminal intent of offender can be effectively cut down, offender is finally forced to abandon theft vehicle.

In addition it is also possible to which executing theft shown in Fig. 7 as described above in the sides ECU3 or 4 side of anti-theft module copes with engine control Processing procedure sequence executes the program to be substituted in 21 side of theft management center.In this case, from 21 side of theft management center to vehicle 1 side sends the program of Fig. 7 as theft reply engine control instruction, to utilize the ECU3 or anti-theft module for receiving the instruction 4 execute the program of Fig. 7.Since script knows the transport condition of vehicle 1, the operating status of engine by ECU3, it is based on The program of Fig. 7 switches the control content to engine successively, without these information are sent to 21 side of theft management center, also can Obtain function and effect same as described above.

In addition, the function of the theft reply engine control program based on above Fig. 7 also can be suitably used for embodiment 1. In this case, it as long as the function to be assigned to the theft determination unit 13 of the anti-theft module 4 in embodiment 1, is stealing The steps limitation of engine output reduction etc. is individually undertaken when surreptitiously by vehicle 1, therefore, effect effect same as described above can be obtained Fruit.

On the other hand, in the case of communication disruption between 1 side of vehicle and theft management center 21,1 side of vehicle is utilized The theft determination unit 13 of anti-theft module 4 replace the theft determination unit 25 of 21 side of theft management center to execute at theft inhibition Reason.Theft at this time inhibits processing identical as embodiment 1, based on tilt variation, vibration detection or this truck position information come pair Whether generation theft is judged, suitably carries out prediction address to surrounding using loudspeaker 14, headlamp 15.

In addition, when in user in the case of taking away vehicle 1 at the moment, based on being made from user side to theft management center 21 The notice of the vehicle theft gone out sends abnormal notification instruction and theft reply engine control from theft determination unit 25 to 1 side of vehicle Instruction.Processing is also executed by 1 side of vehicle as described above even in this case as a result, to try hard to vehicle theft Inhibited.

On the other hand, forbid processing identical as embodiment 1 based on the ID engine starts checked, if in the sides ECU3 and preventing Stealing in the ID authentication departments 6,10 of 4 side of module is associated mutual ID to register, then in engine start later with each From ID authentication departments 6,10 in ID unanimously for condition come enforcement engine start, engine start is made in the case where ID is inconsistent Forbid, therefore, vehicle theft can be prevented in possible trouble.

In addition, if the user for having purchased the motorcycle 1 of no anti-theft module 4 is additional in use to install anti-theft module 4, then it can be automatically associated with the ID of anti-theft module 4 by the ID of ECU3 and registers mutually.As a result, not by motorcycle 1 with extremely sale Dealer etc. can very easily obtain the anti-theft feature based on ID certifications.

Then, in order to carry out fault diagnosis and the engine in the case that diagnostic tool 19 is connected to ECU3 to vehicle 1 The execution step of force start is described.

First, when the engine of 1 side of vehicle, control systems or equipment class etc. are abnormal, alarm lamp is lighted, and will be with The corresponding failure code of anomalous content is preserved to ECU3.At the same time, ECU3 is via 3G, 4G communication unit 23, to anti-theft pipe Reason center 21 sends out the request for the specific operation condition for sending engine force start.If according to the request from theft management center 21 ID registers 24 send specific operation condition to 1 side of vehicle, then input and ECU3 and temporarily deposited via 3G, 4G communication unit 23 Storage.

If by identifying that out of order user with to dealer etc. is sold, incites somebody to action vehicle 1 based on lighting for alarm lamp Diagnostic tool 19 is connected instead of anti-theft module 4 with the connector 18 of the K-Line17 of ECU3, therewith in ECU3 and anti-theft module 4 Between ID can not be mutually authenticated.User will be registered in the specific operation item at theft management center 21 together with the ID of itself Part is supplied to the technical staff of sale dealer, technical staff to be grasped according to specific operation condition when needing engine start Make.As a result, without ID certifications also can force start engine, so as to unquestionably implement fault diagnosis.

In addition, the specific operation condition for being stored in ECU3 is made to be responsible for the limitation of timeliness and number.For example, as limitation Time is set as by ECU3 from detaching anti-theft module 4, by 24 hours, ECU3 being automatically deleted if having spent 24 hours Interior specific operation condition can not execute force start even if according to specific operation condition operation.In addition, setting 5 It is secondary to be used as limited number of times, even if being operated for the operation more than 5 times according to specific operation condition within the limitation time Do not execute force start.

By the limitation time setting of specific operation condition as no matter how the defect content of vehicle 1 can complete diagnosis Time enough, in addition, by the limited number of times setting of specific operation condition as no matter how defect content is required in failure Enough numbers of engine start in diagnosis.As a result, the common fault diagnosis at sale dealer will not be caused to hinder completely Hinder, if by the limitation time after the completion of fault diagnosis, the specific operation condition being automatically deleted in ECU3.

As a result, during using vehicle 1 by user later, it can prevent from using the spy in ECU3 by offender's malice The case where operating condition carrys out force start engine is determined in possible trouble.

In addition, it must be not necessarily automatically deleted the specific operation condition in ECU3, such as can also be always by specific operation Condition is stored in ECU3.

In addition, since the connection of diagnostic tool 19 can be identified in the ECU3 in fault diagnosis, in addition to specific behaviour Make other than condition, such as the condition that is connected to of diagnostic tool 19 can also be carried out enforcement engine force start.According to such Structure can further be reliably prevented illegal engine force start.

Therefore, during the use of motorcycle 1, ECU3, anti-theft module 4 it some times happens that failure and cause to carry out Unit replacement.In addition, causing user that change occurs because of the transfer of motorcycle 1 sometimes, (mail address is opened for engine pressure Dynamic specific operation condition also necessarily changes), in turn, new user is possible to feel produced by 3G, 4G communication unit 23 Communication expense become burden and wish obtain theft prevent function.

Therefore, for the failure of such as ECU3, anti-theft module 4, user will using registration mail address after user changes ID re-registration requests are collectively notified theft management center 21 with the ID (or preset password etc.) of itself, as item Part re-registers ID in the ID registers 24 at theft management center 21.As specific step, such as in ID registers The registration ID for the side for having carried out unit replacement is only deleted in 24, or is deleting 4 respective registration of ECU3 and anti-theft module On the basis of ID, ID notice requests, the ID and use that will be replied from 1 side of vehicle are sent to 1 side of vehicle using above-mentioned steps again The ID at family is associated to be registered.

In addition, being changed for user, ID is erased request together with the ID of itself by old user using registration mail address It notifies to theft management center 21, deletes the ID and ECU3 associated therewith of old user in ID registers 24 as condition With the ID of anti-theft module 4.All ID are restored to unregistered original state by ID registers 24 as a result, by the postal of new user Part address and specific operation condition are registered together with its ID, are on this basis again asked ID notices using above-mentioned steps It asks and is sent to 1 side of vehicle to be registered to each ID.

In addition, the case where wishing to obtain anti-theft feature for new user, in the same manner as described above smears the ID from old user All ID of ID registers 24 are deleted except the notice of request is echoed, on this basis from theft management center 21 to vehicle 1 side sends normal mode switching command.The pattern switching portion 7 of ECU3 is back to usual mould based on the normal mode switching command Formula could start determination unit 8 and be fixed to permission side, as a result, ECU3 restPoses.Therefore, if hereafter new user Anti-theft module 4 is detached from ECU3, then can remove anti-theft feature from motorcycle 1.

[embodiment 3]

Then, to the present invention is embodied as the implementation of the other anti-theft devices 2 to cooperate with theft management center 21 Mode 3 illustrates.

Fig. 8 is the overall structure figure of the anti-theft device 2 for the motorcycle 1 for indicating embodiment 3.

With theft management center 21 cooperate this put it is identical as embodiment 2, main difference is that, engine opens The ID certifications of ECU3 and anti-theft module 4 when dynamic are executed in 21 side of theft management center.Therefore, it omits and embodiment 2 The explanation of something in common illustrates difference emphasis.

By the way that ID authentication functions are transferred to 21 side of theft management center from ECU3 and 4 side of anti-theft module, to ECU3 and Have the ID registers 27,28 without authentication function in anti-theft module 4, has with authentication function in theft management center 21 ID authentication departments 29.

The ECU3 that is carried out to theft management center 21, anti-theft module 4, each ID register steps of user are substantially and embodiment party Formula 2 is identical, if by user by the specific operation condition notification of information of vehicles, mail address and engine user force start to anti- Administrative center 21 is stolen, then is registered these information to ID authentication departments 29.If according to the notice of the ID from theft management center 21 Request the ID registered in the ID authentication departments 27,28 of the ECU3 of 1 side of vehicle and anti-theft module 4 is replied, then by its It is registered to ID authentication departments 29 in the state of associated with User ID etc..

Forbidding for the engine start based on the ID verifications in theft management center 21 is executed with step as described below Processing.

First, it in 1 side of vehicle, will be stepped in the ID authentication departments 27,28 of ECU3 and anti-theft module 4 when engine starts every time The ID of note is sent to theft management center 21 as request signal via 3G, 4G communication unit 23.At theft management center 21 In ID authentication departments 29, the registration ID of the ID of received ECU3 and ECU3 is checked, and by received antitheft mould The ID of block 4 and the registration ID of anti-theft module 4 are checked.

Then, in the case where the ID of ECU3 and anti-theft module 4 are consistent, using ID authentication departments 29 by ID consistent informations In response signal and return back to 1 side of vehicle.In addition, (the either side of ECU3 and anti-theft module 4 in the case of in addition to this ID or both sides the inconsistent situations of ID, or do not receive as request signal the feelings of ECU3 or the ID of anti-theft module 4 Condition), using ID authentication departments 29 by the inconsistent information of ID in response signal and return back to 1 side of vehicle.

By the response signal from theft management center 21 from 3G, 4G communication unit 23 of anti-theft module 4 via the mould of ECU3 Formula switching part 7, which is input to, could start determination unit 8, and it is ID consistent informations that could start determination unit 8 in the content of response signal In the case of, switching to allows side, in the case of the content of response signal information inconsistent for ID, switches to and forbids side.

Therefore, though being not repeated, in the case where the inconsistent judgements of ID are made in 21 side of theft management center, Forbid engine start using ECU3 in 1 side of vehicle based on the inconsistent information of ID, therefore, vehicle theft can be prevented in possible trouble.

Therefore, in the present embodiment, lead between 21 side of 1 side of vehicle and theft management center when engine starts every time Mobile phone circuit is crossed receive and send messages (response signal and request signal), therefore, engine can not be started when breaking in the communications.It is false Be located under such circumstances, in the present embodiment, by user according to the engine force start described in embodiment 2 Specific operation condition is come in the case of being operated, engine can also be started by not receiving ID consistent informations.In addition, therefore will be specific Operating condition is stored in ECU3 always.

As a result, in the case where not starting engine carrying out start-up operation, user meets specific operation by executing The operation (for example, 5 throttle wide operations are carried out within 5 seconds) of condition, so as to not have any problems starts engine To make vehicle 1 travel.Specific operation condition is the self-determining condition of user, and therefore, the third party is difficult to illegally obtain, can be fully Ensure its safety.

In addition, in such communication disruption, bluetooth, Wireless LAN can also be utilized.Such as in advance by bluetooth, Wireless LAN Function assigns anti-theft module 4, if engine can not start, by ID consistent informations in response signal and from the mobile phone of user It is sent to anti-theft module 4 via bluetooth, Wireless LAN.If in addition, using the preset password of institute when sending, can ensure that Safety.Moreover, the anti-theft module 4 for receiving ID consistent informations executes and returns to ID consistent informations with from theft management center 21 The identical processing of situation starts engine with capable of not having any problems.

The explanation to embodiment is completed above, but the mode of the present invention is not limited to the embodiment.Such as In the above embodiment, the anti-theft device 2 for two-wheeled motor vehicle 1 is embodied, however, it is not limited to this.Such as ID can be based on Certification forbids being equipped on the startup of the engine of motor tricycle, ship, is equipped on by utility engines used in generator In the case of golf cart, snow breaker etc., the startup of these engines can also be forbidden based on ID certifications.

In addition, in the above embodiment 1, mutual ID is mutually authenticated between ECU3 and anti-theft module 4, but It is not limited thereto, such as (the engine start judgement of independent ID authentication devices can also be set between ECU3 and anti-theft module 4 Unit), the ID of ECU3 and anti-theft module 4 are authenticated respectively using the ID authentication devices.

In addition, in the above-described embodiment, as based on Fig. 2,3 it is illustrated as, come to ECU3 and prevent via K-Line It steals module 4 to be attached, however, it is not limited to this, such as can also use CAN (Controller Area Network：Controller LAN) etc. replace K-Line.
