Embodiment
Below, with reference to accompanying drawing the onboard system as the preferred implementation of start-control device of the present invention and two-way tuner is elaborated.
In the prior art, the onboard system that carries out the starting of vehicle motor has two kinds of mechanical type and electronic types.In mechanical type, key is inserted lock core and carries out the starting of motor through manual screw key.Electronic type is known as so-called starting (push start) mode of pushing, and generates the engine start signal through push-botton operation.The present invention is applicable to mechanical type and electronic type both sides.With reference to Fig. 1~Fig. 5 the application of the present invention in mechanical type described, the application of the present invention in electronic type described with reference to Fig. 6.
Fig. 1 is the summary structural drawing of onboard system 10 with start-control device of first embodiment of the invention.Onboard system 10 is mechanical type systems.As shown in the drawing, onboard system 10 is connected with vehicle body ECU (Electrical Control Unit) 12 and engine control ECU (so-called EFi) 15 in bus network 11.
And, on vehicle body ECU12, also be connected with remote-control key tuner 13, door lock motor 14, reach remote start(ing) ECU20, on Engine ECU 15 and remote start(ing) ECU20, be connected with anti-theft device for vehicle (イ モ PVC ラ イ ザ) 16.
In addition, the anti-theft device for vehicle amplifier 17 that is connected with anti-theft device for vehicle 16 be configured in the lock core 18 that inserts car key 5 near.
Engine control ECU15 is the control gear of control motor (not shown) molar behavior.Particularly; Engine control ECU15 is corresponding to begin action with being connected of ignition circuit (IG); When detecting not shown piloting engine when beginning to rotate with being connected of trigger circuit (ST); Then carry out spraying and IGNITION CONTROL, thereby make engine startup operation to the fuel of motor.In addition, when ignition circuit (IG) when opening circuit, stop fuel and spray and motor is stopped.
At this, engine control ECU15 for example obtains engine speed etc. about the information of engine condition, and uses it for the control of motor.In addition, engine control ECU15 communicates via bus network 11 and vehicle body ECU12 etc., receives the output information of vehicle body ECU12, and sends information via bus network 11 to vehicle body ECU12.
Anti-theft device for vehicle 16 is to be used to the device that prevents that vehicle is stolen.That is, key 5 has the key code that authentication is used, and when key 5 was inserted lock core 18, anti-theft device for vehicle 16 utilized key code to carry out authentication.When authentification failure, anti-theft device for vehicle 16 is forbidden the starting of motor, only when authentication success, removes starting and forbids.
Order when utilizing anti-theft device for vehicle 16 releasing engine starts to forbid is specially: at first, lock core 18 detects the insertion of keys 5 and also notifies to anti-theft device for vehicle 16 (order 1).16 pairs of anti-theft device for vehicle amplifiers of notified anti-theft device for vehicle 17 are carried out key code and are sent request (order 2).So anti-theft device for vehicle amplifier 17 carries out radio communication with key 5, in the XPNDR Transponder (not shown) that is contained in the key 5 read the key code of storage and send it to anti-theft device for vehicle 16 (order 3).16 pairs of anti-thefts device for vehicle carry out conformity from anti-theft device for vehicle amplifier 17 key code that receives and the key code of self storing in advance and judge; When being judged to be unanimity, give and engine control ECU15 starting permission as authentication success, (order 4) forbidden in the starting of removing motor thus.
Therefore; When the user will insert in the lock core 18 through the key 5 of authentication; Anti-theft device for vehicle 16 is automatically removed the starting of motor and is forbidden, the user is through the rotating operation of key 5, and operation ignition circuit and trigger circuit, the power supply that also has the subtend on-vehicle machines is supplied with the auxiliary line of managing (ACC) and driving is piloted engine; Thus, engine control ECU15 carries out fuel control, IGNITION CONTROL and pilots engine.On the other hand; When inserting incorrect key in the lock core 18; Since can not obtain be stored in anti-theft device for vehicle 16 in key code consistent, so engine control ECU15 is in the starting illegal state, drives and pilots engine even carry out the rotating operation of key; Engine control ECU15 can not move yet, thereby motor can not start.
Vehicle body ECU12 is the control gear that carries out the car body State Control, especially carries out locking and unblanking based on the car door (not shown) of the action of door lock motor 14 control.In addition, vehicle body ECU12 is connected with remote-control key tuner 13 and bus network 11, when the information of input is exported to bus network 11, communicates with engine control ECU15 via bus network 11.
Remote-control key tuner 13 carries out and the communicating by letter of remote-control key 1 through antenna.Remote-control key 1 is the remote-controlled operation terminal that the user holds, and onboard system 10 is sent the request of locking of car door and unblanks to ask, reaches the alarm output request for the people of vehicle-surroundings.Key 5 promptly can be two different keys with remote-control key 1, also can one turn to a key.
When vehicle body ECU12 when remote-control key tuner 13 receives various vehicles control requests (door locking request, door open request, alarm request); Carry out control (door locking, open, the alarm of door) based on the control request that receives; Simultaneously, the control request that receives is intactly sent to remote start(ing) ECU20.
Remote start(ing) ECU20 do not insert lock core 18 at key 5, promptly under the state outside the user is in car, the processing of piloting engine.At this moment, for the starting of 16 pairs of motors of freeing vehicle anti-theft device is forbidden, remote start(ing) ECU20 store authentication with key code said function of holding with key 5 with information with as the vehicle anti-theft code.
Remote start(ing) ECU20 portion within it has: instruction identification part 21, tuner joint 22 and master control part 23, master control part 23 portion within it also has: door lock control device 24, notifier processes portion 25 and starting control device 26.
Instruction identification part 21 is discerned the processing whether the control request that receives from vehicle body ECU12 has formed instruction.For example; (for the first time, the second time is short carrying out three door lock requests continuously; Long for the third time) time, this instruction is regarded as the engine start request with a series of request, like this; Through the combination of vehicle launch request is taken as is instruction, then can use the remote-control key 1 of the function that originally only has the locking and unblank of request door, gives the alarm to vehicle-surroundings to carry out other control (is engine start at this).In addition,, can carry out suitable change, in addition, also can form the instruction of the control beyond the request engine start in the instruction of this an expression example only.
On the other hand, tuner joint 22 is and the two-way tuner 3 outside connection sets that are connected.Tuner joint 22 possesses: the connector and the transfer circuit (not shown) that transmits signal that can connect transmission cable.Two-way tuner 3 and remote start(ing) ECU20 are through waiting transmission cable (not shown) physical property to be connected and can to carry out both-way communication by wiring in the car.This transmission cable combines with the connector of tuner joint 22.From the signal of two-way tuner 3 via this connector input tuner joint 22, and and then the transfer circuit through tuner joint 22 pass to master control part 23.As transfer circuit, as long as have the correct function of transmitting signal between connector and master controller 23.Therefore, tuner joint 22 can be designed to simpler structure.That is, tuner joint 22 can be realized with lower one-tenth originally, even remote start(ing) ECU20 has this tuner joint 22, remote start(ing) ECU20 cost can not rise significantly yet.
Two-way tuner 3 is communicated by letter with two-way remote control 2 through radio communication.The communication distance of two-way remote control 2 is longer than remote-control key 1.When receiving control request such as engine starts from two-way remote control 2 when two-way tuner 3, the control request that is received is inputed to tuner joint 22.So, the control request that inputs to tuner joint 22 further is transfused to master control part 23 through tuner joint 22.Two-way tuner 3 further receives the transmission request that starts ECU20 from remote control through tuning joint 22, and to information such as two-way remote control 2 transmission vehicle-states.
Two-way remote control 2 is different with remote-control key 1; Be that the remotely-controlled remote-controlled operation of motor terminal is carried out in supposition; Therefore, the dedicated operations button of engine start request can be provided for sending, and the control signal of specific assigned can be sent to the engine start request.
Therefore, remote start(ing) ECU20 carries out the starting control based on the motor of starting control device 26 when the vehicle control request of sending from remote-control key 1 forms the engine start instruction and when two-way remote control 2 receives the engine start requests.That is, starting control device 26 can be general in the remote starting of the remote starting of using remote-control key and use two-way remote control 2.Can import in the control device 26 from the demand signal of remote-control key 1 with from both sides' signal of the request of two-way remote control 2 in starting.In order to carry out the input of this both sides' signal reliably, it is desirable to the communication protocol of using from the demand signal of remote-control key 1 is set at different communication protocol with the communication protocol of using from the demand signal of two-way remote control 2.
At this, explain based on the starting control device 26 engine start the time order.At first, identification is from the situation (order 1) of remote-control key 1 or two-way remote control 2 request engine starts.Then, receive this start request and execution releasing request (order 2) in anti-theft device for vehicle 16.Anti-theft device for vehicle 16 receives the request of releasing and carries out the authentication of remote start(ing) ECU20, if authentication success then gives engine control ECU15 starting permission, notifies remote start(ing) ECU20 to remove starting simultaneously and forbids (order 3).Afterwards, remote start(ing) ECU20 also exports the starting control (order 4) that analogue signal is carried out motor respectively through operation auxiliary line, ignition circuit, trigger circuit.
From the starting control request that two-way remote control 2 not only sends motor, also can send the request of vehicle control arbitrarily (door locking request, door open request, alarm request etc.).For example, when two-way remote control 2 sent the request of locking of door and unblanks to ask, door lock control device 24 received and is somebody's turn to do control request, locking and unblanking vehicle body ECU12 request door.Likewise, when two-way remote control 2 sent the alarm request, master control part 23 received and should control ask, to vehicle body ECU12 request carrying out alarm.
In vehicle body ECU12, when the vehicle control request that receives from remote start(ing) ECU20, also and when remote-control key tuner 13 receives vehicles control request, likewise carry out control (for example, the action of door lock motor 14 is controlled).In addition, though notify to remote start(ing) ECU20 from vehicle body ECU12 from the vehicle control request of remote-control key tuner 13 receptions,, ask to it is desirable to not notify to remote start(ing) ECU20 for the vehicle control that receives from remote start(ing) ECU20.
In addition, also can be from remote start(ing) ECU20 to two-way remote control 2 announcement informations.This notification of information is carried out through following process: notifier processes portion 25 sends the signal of the information that expression should notify to two-way tuner 3 via tuner joint 22 and transmission cable; And then two-way tuner 3 sends this signal through radio communication to two-way remote control 2.As the content of notice, can notify starting control device 26 and the control result of door lock control device 24 or any information of relevant vehicle such as vehicle-state, diagnostic message.
For control result's notice, when starting control, will control result notification and give two-way remote control 2 when receiving the engine start request from two-way remote control 2.But when starting control when receiving the engine start request instruction from remote-control key 1, remote-control key 1 does not receive the function of information.At this moment, though also can not control result's notice, also can give two-way remote control 2 with receiving the result notification of controlling from the indication of remote-control key 1.
Below, the control processing of request action from remote-control key 1 describes to basis with reference to Fig. 2.As shown in the drawing, at first, the signal (step S101) that remote-control key tuner 13 reception remote-control keys 1 send, vehicle body ECU12 simultaneously, pass to remote start(ing) ECU20 (step S102) with the signal that receives according to the SC sigmal control door lock motor 14 that receives.
Instruction identification part 21 in the remote start(ing) ECU20 judges whether the signal that receives forms instruction (step S103), and (step S104) does not then remain untouched and finishes this processing if instruction is false.
And if the instruction establishment (step S104, the time), then to start control device 26 to carry out starting control (step S105) according to the instruction of setting up, notifier processes portion 25 will control result notification to two-way remote control 2 (step S106), end process.The locking of door, unlock operation also can carry out equally.
Below, the control processing of request action from two-way remote control 2 describes to basis with reference to Fig. 3.As shown in the drawing, at first, whether signal (step S201), two-way tuner 3 authentication signals that bidirectional remote control tuner 3 receives two-way remote control 2 transmissions are (the step S202) that send from regular two-way remote control.The authentication that contains in the signal that this authentication is sent according to two-way remote control 2 with code and the authentication of in two-way tuner 3, storing in advance with code consistent carrying out whether.
When this authentification failure (can not confirm be from signal that regular controller sends time) (step S203 not), intactly stops and should handle.
And when authentication success (can confirm be from signal that regular controller sends time) (step S203 is), two-way tuner 3 passes to remote start(ing) ECU20 (step S204) via tuner joint 22 with the signal that receives.
The starting control device 26 of remote start(ing) ECU20 is carried out starting control (step S205) according to the signal that receives, and notifier processes portion 2 will control result notification and give two-way remote control 2 (step S206), end process.The locking of door, unlock operation also can carry out equally.
Two-way tuner 3 and two-way remote control 2 can be packed in the onboard system 10 to replace being arranged on the outside of onboard system 10.In addition, be not limited to two-way tuner 3 is connected on the humorous device joint 22 always.
Under the state that does not connect two-way tuner 3, can pilot engine at a distance through remote-control key 1, if be connected with two-way tuner 3, then can use two-way remote control 2 to carry out remote start(ing) at a distance.
Like this, no matter whether two-way tuner 3 connects, and can carry out the starting control of motor, and in addition, whether the two-way tuner 3 of the processing of remote start(ing) ECU20 action connects all is same.
Therefore, can be through under original state, not connecting the cost that two-way tuner 3 suppresses onboard system 10.That is, the user can be connected to two-way tuner 3 on the tuner joint 22 in the stage afterwards as required simply.
Here, though be, also can carry out this authentication at remote start(ing) ECU20 at two-way tuner 3 authentication two-way remote controls 2.
When having connected two-way tuner 3, except can prolonging the distance that can start at a distance, can also information be provided to the user, this point also is the aspect that function improves.As the information that offers the user, except that remotely-controlled control result, also have vehicle at this constantly state, particularly, the open and-shut mode of the operating condition of motor, car door and vehicle window, room temperature, no abnormal etc. notice is arranged.In addition, also can notify motor abend the experience etc. diagnostic message.
Fig. 4 shows the concrete example of the diagnostic message of expression motor stop reason.As shown in the drawing; In engine start by remote manipulation; When door is turned on, when the cover of door when unblanking, engine compartment is turned on, when speed change lever beyond P the time, when carrying out brake operating, the bright lamp of motor inspection tutorial light, when the rotating speed of motor is unusual, produce the speed of a motor vehicle when unusual; Do not carry out engine start, if motor just makes it stop at work.
It is inner that the experience that this motor stops to be stored in remote start(ing) ECU20, can be to replying transmission from the request of two-way remote control 2.
At this, be that example is illustrated with the diagnostic message of remote start(ing) ECU20 management, still, also can further obtain the diagnostic message beyond other the remote starting of ECU management and send to two-way remote control 2.
Below, explain that with reference to Fig. 5 the concrete structure of two-way tuner is routine.In the structure example shown in this figure, the inside of two-way tuner 3 has: control is with microcomputer 31, communication interface 32, EEP-ROM33, receiving machine 34a, transmitter 34b and switch 35.
Control is control devices of the two-way tuner 3 of whole control with microcomputer 31, and the transmission source that has signal is the authentication function that two-way remote control 2 carries out authentication.In addition, communication interface 32 is to carry out the interface that data are sent, received with remote start(ing) ECU20.Carry out the physical property outside through this communication interface 32 via transmission cable and the tuning joint 22 of remote start(ing) ECU20 and be connected, two-way tuner 3 can both-way communication with remote start(ing) ECU20.Particularly, expression engine start control request waits the signal of vehicle control request to send to remote start(ing) ECU20 from two-way tuner 3 via transmission cable.The signal of the information that control result that on the other hand, control is asked based on vehicle or other expression are relevant with vehicle sends to two-way tuner 3 from remote start(ing) ECU20 via transmission cable.Like this, transmission cable can be applied to both-way communication, and still, this transmission path both can be made up of a paths, also can be made up of mulitpath.In addition, EEP-ROM33 is used to store the storage area of authentication with code etc.
Receiving machine 34a, transmitter 34b particularly are made up of IC34, and receiving machine 34a receives processing to the information from two-way remote control 2, and transmitter 34b carries out handling to the transmission of remote controller 2.
In addition, send to handle and receive to handle and switch through switch 35, the switching of switch 35 is according to coming Self Control to carry out with the control signal of microcomputer 31.
