JP 2007-170162 A

  By the way, this type of electronic key system is a system type in which the key code of the vehicle key is electronic data, which is transmitted to the vehicle by wireless communication and key verification is performed, but it is difficult to imitate such electronic data. Due to the high nature of this system, the vehicle key is difficult to duplicate. Therefore, when an electronic key system is used for a vehicle key system, there is an advantage that vehicle theft is less likely to occur than in the case of a mechanically operated key system using a mechanical key as a vehicle key. However, even if the electronic key system is highly effective in preventing vehicle theft, if the electronic key itself is stolen, the vehicle will be stolen, so the vehicle will be stolen even in such a situation. There was a demand for measures to make it difficult.

  An object of the present invention is to provide an engine start system capable of killing a theft by a theft and making it difficult for the vehicle to be stolen.

In order to solve the above-described problems, the present invention provides an electronic key system that performs key verification by comparing a key code transmitted from an electronic key capable of wirelessly transmitting a key code inherent to the key with a vehicle. In an engine start system that is mounted on a vehicle and the establishment of the key collation is an engine start condition, the vehicle is provided on the vehicle and operated under the condition of the key collation establishment of the electronic key system. Engine starting operation means for starting the engine with the power supply state being electrically started, and a paddle capable of at least one of pulling operation and pushing operation in the gripping state where the steering wheel of the vehicle is gripped Type operation means and actual operation performed by the paddle type operation means are required when permitting or executing the start of the engine. A determination unit that determines whether or not the registered pattern registered in the storage unit as an operation procedure of the paddle type operation unit matches, and the key verification of the key system is established, and the paddle type operation unit Control means for permitting or executing start of the engine on condition that an actual operation matches the registered pattern of the storage means, and the paddle type operation means sets the gear position of the transmission of the vehicle. An operation system used for switching, wherein the determination means performs the registration of the actual operation performed by the paddle type operation means in a state where the engine remains stopped after the operation of the engine start operation means. It is determined whether or not the pattern matches, and the control means operates the engine start operation means while the key verification of the electronic key system is established. The actual operation performed by the paddle type operating means is summarized in that it permits or executes the starting of the engine on condition that coincides with the registered pattern of the storage means after.

  According to this configuration, the engine start condition of the vehicle includes not only the establishment of key verification by the key system but also whether or not the paddle type operation means is operated in accordance with a registered pattern registered in the vehicle in advance. . Here, for example, if a thief tries to steal a vehicle by stealing a key, the vehicle engine cannot be started without knowing the operation procedure of the paddle type operation means. In this case, steal the vehicle. I can't. Also, even if the thief tries to match the registered patterns by operating the paddle-type operation means, it is necessary to try each of the many existing patterns one by one. Is troublesome and troublesome. Therefore, if the operation of the paddle type operation means is also included in the engine starting condition, it is possible to greatly kill the thief's willingness to steal and secure high vehicle theft prevention.

Further , according to this configuration, the paddle type operation means is shared by a registration pattern input which is a requirement for determining whether or not to permit engine start and an operation input for switching the shift position of the transmission of the vehicle. . For this reason, it is possible to use the same operation system for the registration pattern input and the shift position switching input, so it is not necessary to prepare different operation systems for these inputs, and the number of parts can be reduced. Become. Further, according to this configuration, after operating the engine starting operation means, the paddle type operation means is used to input the registration pattern, and this input operation is performed under the condition that the key verification by the electronic key system is established. If done correctly, engine start is allowed or executed. Therefore, it is possible to start the engine by a series of operations in which it is difficult to feel a sense of incongruity of operating the engine start operation means and then operating the paddle type operation means to input the registered pattern.

  In the present invention, when the request operation for changing the registration pattern registered in the storage means is performed by the paddle type operation means, the vehicle is set to the registration pattern change mode, and the paddle type is used in the registration pattern change mode. The gist of the invention is that it includes a registration pattern changing unit for registering an operation procedure input by the operation unit in the storage unit as a new registration pattern.

  According to this configuration, the registered pattern registered in the storage unit can be freely changed using the registered pattern changing unit. Therefore, if the registration pattern of the storage means is changed periodically, a new registration pattern is registered in the vehicle each time, so that the registration pattern does not become old and it is possible to make vehicle theft more unlikely to occur. Become.

  ADVANTAGE OF THE INVENTION According to this invention, it can make it difficult to generate vehicle theft by killing the theft intention of a theft.

Hereinafter, an embodiment of an engine starting system embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1 and FIG. 2, a pair of operation systems capable of switching the shift position of an automatic transmission (not shown) of the vehicle 1 by manual operation is provided at the rear surface position of the spoke portion 3 in the steering wheel 2 of the vehicle 1. Paddle switches 4 and 5 are provided. One of the pair of paddle switches 4 and 5 is for manual shift-up operation of the automatic transmission, and the other is for manual shift-down operation of the automatic transmission, so that both the shift-up operation and the shift-down operation can be performed. It has become. In the case of this example, the right paddle switch 4 positioned on the right side when viewed from the driver is used for the upshift operation, and the left paddle switch 5 positioned on the left side when viewed from the driver is used for the downshift operation. The paddle switches 4 and 5 correspond to paddle type operation means.

  Since the paddle switches 4 and 5 are formed in the spoke portion 3 of the steering wheel 2, the paddle switches 4 and 5 rotate together with the steering wheel 2 when the steering wheel 2 is rotated. The paddle switches 4 and 5 can be tilted to the front side from the initial position, and are momentary that automatically return to the original initial position when the hand is released from the paddle switches 4 and 5 after pulling the front side. . The paddle switches 4 and 5 are arranged at positions where a pulling operation can be performed with a finger at that time when the steering wheel 2 is gripped and operated. At the tip of the paddle switches 4 and 5, a hooking portion 6 is formed extending upward so that the finger can be easily hooked during a pulling operation.

  As shown in FIG. 3, the vehicle 1 is equipped with a key operation free system 7 capable of performing vehicle operations such as door locking / unlocking and engine start / stop without actually operating the vehicle keys. . In the key operation free system 7, a portable device 8 capable of transmitting a key-specific ID code (key code) by wireless communication is used as a vehicle key. The key operation free system 7 transmits a request signal Srq as an ID code reply request from the vehicle 1, and when the portable device 8 receives this request signal Srq, the portable device 8 puts its own ID code in response to the request signal Srq. When the ID signal Sid is returned to the vehicle 1 by narrow-range communication and the ID code of the portable device 8 matches the ID code of the vehicle 1, door locking / unlocking and engine start / stop are permitted or executed. The key operation free system 7 corresponds to a key system (electronic key system), and the portable device 8 corresponds to a key (electronic key).

  The key operation free system 7 includes a smart entry system 9 as a function that does not require actual vehicle key operation at the time of door lock locking / unlocking operation. The smart entry system 9 will be described below. The vehicle 1 is provided with a verification ECU 10 that performs ID verification when performing narrow-area communication with the portable device 8. The verification ECU 10 includes an in-vehicle LF transmitter 11 that is embedded in each door of the vehicle 1 and can transmit an LF band signal outside the vehicle, and an in-vehicle LF that is embedded under the vehicle floor and can transmit an LF band signal in the vehicle. The transmitter 12 is connected to an RF receiver 13 that is embedded in an in-vehicle rearview mirror or the like and can receive an RF band signal. These LF transmitters 11 and 12 can transmit the request signal Srq to the surroundings, and the outside LF transmitter 11 forms a communication area (outside vehicle communication area) of the request signal Srq around the vehicle. Forms a communication area (in-vehicle communication area) for the request signal Srq throughout the vehicle.

  For example, a touch sensor 15 embedded in an outside door handle knob 14 is connected to the verification ECU 10. The touch sensor 15 detects an operation of touching the outside door handle knob 14 when the operator releases the locked door lock. For example, a lock button 16 provided on the outside door handle knob 14 is connected to the verification ECU 10. The lock button 16 is pushed when the operator locks the unlocked door lock. A door ECU 17 that controls locking and unlocking of the door lock is connected to the verification ECU 10 via an in-vehicle LAN 18. The door ECU 17 controls the door lock motor 19 based on a command from the verification ECU 10 to place the door lock in a locked state or an unlocked state.

  When the vehicle 1 is in a parked state (engine stop and door lock locked state), the verification ECU 10 intermittently transmits a request signal Srq for the LF band from the external LF transmitter 11 to form an external communication area around the vehicle. When the portable device 8 enters the outside communication area and receives the request signal Srq, the portable device 8 responds to the request signal Srq and sends the ID signal Sid carrying the ID code registered in its own memory 20 to the RF band. Reply with the signal. When smart communication is established when the RF receiver 13 receives the ID signal Sid by the RF receiver 13, the verification ECU 10 compares the ID code registered in its own memory 21 with the ID code of the portable device 8 (verification outside the vehicle). I do. When the verification ECU 10 recognizes that the verification outside the vehicle has been established, the verification ECU 10 sets an external verification flag in the memory 21 for a certain period of time and activates the touch sensor 15 in the standby state during that period. When the activated touch sensor 15 detects that the outside door handle knob has been touched, the door ECU 17 rotates the door lock motor 19 to one side to unlock the locked door lock.

  On the other hand, when the vehicle 1 is in a stopped state (engine stop and door lock unlocked state), the verification ECU 10 transmits a request signal Srq from the outside LF transmitter 11 when detecting that the lock button 16 is pressed. When the verification ECU 10 receives the request signal Srq and recognizes that the verification outside the vehicle is established in the ID signal Sid returned from the portable device 8, the verification ECU 10 outputs a door lock locking request to the door ECU 17. Receiving the door lock locking request, the door ECU 17 rotates the door lock motor 19 to the other side to lock the unlocked door lock.

  Further, the key operation free system 7 has a one-push engine as a function capable of performing engine start / stop operation only by an engine system switch operation without requiring actual vehicle key operation at the time of engine start / stop operation. There is a start system 22. The one-push engine start system 22 of this example inputs a password by operating the paddle switches 4 and 5 after operating the engine system switch, and this input password Dps matches the registered password Dk registered in the vehicle 1 in advance. If this is the case, the paddle switch password input method is used to start the engine. In addition, the password input method of this example adopts a number input method that expresses a numerical value by the number of operations of the paddle switches 4 and 5. The one-push engine start system 22 corresponds to an engine start system, the input password Dps corresponds to an actual operation, and the registration password Dk corresponds to a registration pattern.

  The one-push engine start system 22 will be described below. An engine switch 23 is provided in the driver's seat of the vehicle 1 as an operation system for switching the power state (power position) of the vehicle 1. The engine switch 23 is a pressing operation type capable of pressing and operating the switch operation portion 23a which is an operation place, and the power supply state is switched every time the switch operation portion 23a is operated. The engine switch 23 is provided with an engine start / stop operation function for switching the engine 24 to a start state or a stop state, and a power supply transition operation function for switching the power state from an off state to an ACC on state or an IG on state. The engine switch 23 corresponds to engine starting operation means.

  An engine switch lamp 25 is provided on the operation surface of the switch operation unit 23a to visually display the power supply state of the vehicle 1. The engine switch lamp 25 includes, for example, a plurality of LEDs having different emission colors, and the emission color is switched according to the power state of the vehicle 1. The engine switch lamp 25 is turned off when the engine 24 is stopped, is lit green when the ACC is on, and is lit orange when the IG is on. When the engine is started, it is temporarily turned off.

  Further, the vehicle 1 includes an engine ECU 26 that performs ignition control and fuel injection control of the engine 24, a shift ECU 27 that detects the range position (gear position) based on the operation of the select lever, and controls the automatic transmission, A power supply ECU 28 that performs power management of electrical components (including the engine switch lamp 25) is provided. These ECUs 26 to 28 are connected to various ECUs such as the verification ECU 10 through the in-vehicle LAN 18. In addition to the engine switch 23 described above, a vehicle speed sensor 29 for detecting the speed of the vehicle 1 and a brake sensor 30 for detecting an operation amount of a brake pedal (not shown) are connected to the power supply ECU 28. Further, an ACC relay 31 connected to various on-vehicle accessories, an IG relay 32 connected to the engine ECU 26, and a starter relay 33 connected to the starter motor of the engine 24 are connected to the power supply ECU 28.

  The vehicle 1 is provided with a paddle shift management ECU 34 that manages operations performed by the paddle switches 4 and 5. The paddle shift management ECU 34 has an input side connected to the paddle switches 4 and 5, and an output side connected to the shift ECU 27 via the in-vehicle LAN 18. The paddle shift management ECU 34 is provided with a CPU 35 for overall control of the ECU 34 and a data rewritable memory 36 in which various programs and data groups are written. The memory 36 is written with a control program Pk executed by the CPU 35 when determining what operation the driver has performed with the paddle switches 4 and 5. The memory 36 corresponds to storage means.

  The CPU 35 (paddle shift management ECU 34) operates according to the control program Pk in the memory 36. Specifically, the CPU 35 monitors operations performed by the paddle switches 4 and 5, and responds to operations of the paddle switches 4 and 5. The paddle operation information Spd is output to the shift ECU 27. The paddle operation information Spd includes operation frequency information indicating how many times the right paddle switch 4 and the left paddle switch 5 are operated. The shift ECU 27 controls the automatic transmission based on the paddle operation information Spd input from the CPU 35 (paddle shift management ECU 34), and switches the automatic transmission to a shift position corresponding to the number of operations of the paddle switches 4 and 5. The paddle shift management ECU 34 is connected to a buzzer 37 that can generate various notification sounds in the vehicle.

  The memory 36 is registered with a password correctness determination program Ppr for checking whether or not the input operation by the paddle switches 4 and 5 given to the driver as a password input when starting the engine is correct. In addition, a registration password Dk is written in the memory 36 as a comparison symmetry of whether or not the input password Dps obtained by the input operation of the paddle switches 4 and 5 at this time is correct. The password correctness determination program Ppr sets the paddle shift management ECU 34 (vehicle 1) to the password input mode when the engine switch 23 is pressed when the engine is stopped, and the input operation performed by the paddle switches 4 and 5 in this mode is the input password. This is a program that takes in as Dps, compares this input password Dps with the registered password Dk, and starts the engine 24 if the input password Dps matches the registered password Dk. Note that the transition to the password input mode is made on the condition that when the engine switch 23 is pressed, the brake pedal is depressed and in-vehicle verification (verification outside the vehicle) is established.

  The CPU 35 operates in accordance with the password correctness determination program Ppr, thereby executing a password correctness determination process for determining whether or not the engine start permission is permitted. In the password correctness determination process of this example, the right paddle switch 4 is used as a numerical value input switch, the left paddle switch 5 is used as an input confirmation switch, and a password is composed of a plurality of digits (for example, four digits from the first digit to the thousandth digit). Digit), input the value with the right paddle switch 4 and confirm the input with the left paddle switch 5 at each position. If the input value is correct at all positions, the input password Dps is determined to be correct. Process.

  When the CPU 35 executes the password correctness determination program Ppr, as shown in FIG. 4, the paddle shift management ECU 34 determines whether the input password Dps is correct or not based on the password correctness determination unit 38 and the determination result of the password correctness determination unit 38. In addition, an operation setting unit 39 that determines whether to permit engine start is functionally generated. The password correctness determination unit 38 and the operation setting unit 39 are functionally generated by the CPU 35 executing the password correctness determination program Ppr. In FIG. 4, these are represented by a block diagram. The password correctness determination unit 38 corresponds to the determination unit, and the operation setting unit 39 corresponds to the control unit.

  The password correctness determination unit 38 performs password verification by comparing the input password Dps and the registered password Dk, and notifies the operation setting unit 39 of the correctness determination result. The operation setting unit 39 sets whether or not to allow engine start based on the correctness determination result obtained from the password correctness determination unit 38. In other words, when the operation setting unit 39 receives a notification that the verification is established from the password correctness determination unit 38, the operation setting unit 39 outputs an engine start start request Est to the power supply ECU 28 to start the engine 24, and the password correctness determination unit 38 does not verify the verification. Is received, the engine start prohibition request Ett is output to the power supply ECU 28 to keep the engine 24 in a stopped state.

  The verification ECU 10 transmits a request signal Srq from the in-vehicle LF transmitter 12 when it recognizes that the driver has boarded by opening the door with the courtesy switch 40 after the vehicle exterior verification is established and the door lock is unlocked. Thus, an in-vehicle communication area is formed throughout the vehicle. When the smart receiver is established by receiving the ID signal Sid returned from the portable device 8 entering the in-vehicle communication area by the RF receiver 13, the verification ECU 10 establishes the ID code registered in itself and the ID code of the portable device 8. ID verification (in-vehicle verification) is performed. When the in-vehicle collation is established, the collation ECU 10 sets an in-vehicle collation establishment flag in the memory 21 and recognizes that the in-vehicle collation is established.

  When the power supply ECU 28 detects that the engine switch 23 is pressed while the brake pedal is depressed, the power supply ECU 28 outputs a password confirmation request Rps to the paddle shift management ECU 34 on the condition that in-vehicle collation is established (external vehicle collation is also possible). To do. At this time, the power supply ECU 28 enters a standby state waiting for a password verification result sent from the paddle shift management ECU 34 thereafter. When the paddle shift management ECU 34 receives the password confirmation request Rps from the power supply ECU 28, the paddle shift management ECU 34 enters the password input mode, waits for the password input using the paddle switches 4 and 5, and when the password is input, the input password Dps and the memory 36 The password is verified against the registered password Dk registered in. When the password verification is established, the paddle shift management ECU 34 outputs an engine start start request Est to the power supply ECU 28.

  When the power supply ECU 28 receives the engine start start request Est from the paddle shift management ECU 34 in the standby state, the power supply ECU 28 starts up the engine ECU 26 while turning on the three relays 31 to 33 to start the engine 24 in the stopped state. Output a signal. The engine ECU 26 that has received the activation signal performs confirmation of the in-vehicle collation result and pairing for confirming whether the collation ECU 10 is paired with itself by encrypted communication. After confirming both of these conditions, the engine ECU 26 starts ignition control and fuel injection control and starts the engine 24. On the other hand, when the power supply ECU 28 detects that the engine switch 23 is pressed while the engine 24 is operating, the three relays 31 to 33 are provided on the condition that the vehicle 1 is stopped (vehicle speed “0”). Are all turned off, and the engine 24 is stopped.

  Further, when the power supply ECU 28 detects that only the engine switch 23 is pressed without the brake pedal being depressed, on condition that the in-vehicle collation is established and the shift lever is at the P range position, Each time the engine switch 23 is operated, the power supply state is switched in the order of OFF state → ACC ON state → IG ON state during one operation. For example, when only the engine switch 23 is pressed when the power state is off, the power state becomes the ACC on state. When the engine switch 23 is further pressed from this state, the power state becomes the IG on state. When the engine switch 23 is pressed again, the power state returns to the off state.

  Next, the detailed operation when the engine 24 is set to the start state by the one-push engine start system 22 of this example will be described according to the flowchart shown in FIG. The flowchart of FIG. 5 is executed on the condition that when the engine switch 23 is pushed, the brake pedal is depressed, and in-vehicle verification (external verification is possible) is established.

  In step 100, the engine switch lamp 25, which has been off until then, blinks orange, for example, to notify the driver that the paddle shift management ECU 34 (vehicle 1) has entered the password input mode. The paddle shift management ECU 34 controls the lighting of the engine switch lamp 25 by outputting a command to the power supply ECU 28.

In step 101, the numerical value input by the right paddle switch 4 is acquired as a numerical value in the thousands of the input password Dps.
In step 102, it is determined whether or not the operation of the left paddle switch 5, that is, the operation of confirming the numeric input of the thousands place has been performed. Here, if the left paddle switch 5 is operated, it is recognized that the input of the thousands digit is completed, and the process proceeds to step 103. If the left paddle switch 5 is not operated, the numeric input of the thousand digits is obtained. Continue.

  In step 103, it is determined whether or not the thousands digit value of the input password Dps input by the right paddle switch 4 matches the thousand digit value of the registered password Dk registered in the vehicle 1 (memory 36). To do. If the thousands digit value of the input password Dps does not match the thousand digit value of the registered password Dk, the process proceeds to step 104, and if these thousand digits match and the password verification matches, the step 105.

  In step 104, the engine switch lamp 25 is switched from the orange blinking state to the extinguished state to notify the driver that the password input was not successful, and the password input mode is terminated.

  In steps 105 to 107, the hundreds digit value of the input password Dps and the hundreds digit value of the registered password Dk are collated in the same procedure as when the input password Dps is thousands. If these passwords Dps and Dk match, the process proceeds to step 109 to continue the numerical verification of the input password Dps. On the other hand, if the passwords Dps and Dk do not match, the process proceeds to step 104 and the engine switch lamp. 25 is turned off to end the password input mode.

  In steps 108 to 110, the tens digit value of the input password Dps and the tens digit value of the registered password Dk are collated in the same procedure as when the input password Dps is thousands and hundreds. If these passwords Dps and Dk match, the process proceeds to step 111 to continue the numerical verification of the input password Dps. On the other hand, if the passwords Dps and Dk do not match, the process proceeds to step 104 and the engine switch lamp. 25 is turned off to end the password input mode.

  In step 111 to step 113, the numerical value of the first digit of the input password Dps and the numerical value of the first digit of the registered password Dk are collated in the same procedure as when the input password Dps is one thousand, one hundred and ten. If the passwords Dps and Dk match, the process proceeds to step 114 and the password input mode is continued. On the other hand, if the passwords Dps and Dk do not match, the process proceeds to step 104 and the engine switch lamp 25 is turned off. And exit password input mode.

  In step 114, the orange blinking interval of the engine switch lamp 25 is further shortened, and the place of all digits of the input password Dps matches the registered password Dk to notify the driver that password verification has been established.

  In step 115, it is determined whether the left and right paddle switches 4 and 5 have been pulled simultaneously. That is, it is determined whether or not this operation has been performed because the trigger operation for starting the engine is that the left and right paddle switches 4 and 5 are simultaneously pulled after password verification is established. Here, if it is recognized that the left and right paddle switches 4 and 5 are simultaneously pulled, the process proceeds to step 116, and if this operation is not performed, the process waits.

  In step 116, the engine ECU 26 starts the engine 24. That is, the engine start start request Est is output to the power supply ECU 28, and the power supply ECU 28 that has received the engine start start request Est turns on all the three relays 31 to 33 and outputs a start signal to the engine ECU 26. 24 is started.

  Therefore, in this example, when starting the engine 24, not only is the condition that key verification (in-vehicle verification) is established by the key operation free system 7, but the correct input password Dps is input by the paddle switches 4 and 5. Whether or not it is necessary is also necessary. For this reason, even if a thief steals the portable device 8 and steals the vehicle 1, the vehicle 1 cannot be moved without stealing the vehicle 1 unless the input password Dps input by the paddle switches 4 and 5 is correctly known. I can't. In addition, even if a thief who does not know the correct input password Dps enters the password in the dark clouds with the paddle switches 4 and 5, it is very unlikely that it will match a suitable password from among a large number of numerical combinations. Will greatly kill the person's willingness to steal vehicles. Therefore, if the input of the password by the paddle switches 4 and 5 is also set as a condition for starting the engine, the anti-theft property of the vehicle 1 can be further improved.

  In addition, the paddle shift management ECU 34 is provided with a mode forcible termination unit 41 that monitors the password input time and forcibly terminates the password input mode when the time is up so that the password input mode has a time limit. Yes. A counter 42 for monitoring the password input time is connected to the mode forced termination unit 41. The mode compulsory ending unit 41 is functionally generated by the CPU 35 of the paddle shift management ECU 34 and the password correctness determination program Ppr. In FIG. 4, this is represented by a block diagram.

  The mode compulsory ending unit 41 measures the elapsed time after the paddle shift management ECU 34 enters the password input mode by the counter 42. If the elapsed time is within the threshold value, the password correctness determination unit 38 performs the password correctness determination processing 38. Allow operation. On the other hand, when the mode forcible termination unit 41 recognizes that the elapsed time since the paddle shift management ECU 34 has entered the password input mode has exceeded the threshold, the mode forcible termination unit 41 issues a forced termination request for stopping the password correctness determination process at that time. The determination result is output to the determination unit 38, and the password correctness determination process performed by the password correctness determination unit 38 is forcibly terminated.

  Therefore, in this example, since the password input time is limited, if the regular password cannot be input within the time limit, the password input mode is forcibly terminated. For this reason, for example, when a theft is working for theft, if the correct password is deceived without knowing it, it will be wasted for that amount of time, and the password input mode will be forcibly terminated after the time limit has expired It is necessary to enter the password from the beginning. Therefore, if such a redoing operation is necessary, it is possible to make a theft report during that time, thus making it possible to further reduce theft of the vehicle. In addition, it is not necessary to leave the password input mode in an unexecuted state for a long time, and it is possible to prevent the in-vehicle battery power from being wasted.

  Further, the paddle shift management ECU 34 is provided with a password change function for rewriting the registered password Dk registered in the memory 36. The password changing function will be described. As shown in FIG. 4, the paddle shift management ECU 34 is provided with a password changing unit 43 that can rewrite the registered password Dk registered in the memory 36 to a new new password Dnw. . The password changing unit 43 is also functionally generated by the CPU 35 of the paddle shift management ECU 34 and the password correctness determination program Ppr, and FIG. 4 represents this in a block diagram. The password changing unit 43 corresponds to a registered pattern changing unit.

  When the password change unit 43 detects that a password change request operation has been performed such as when the left and right paddle switches 4 and 5 are simultaneously operated for several seconds (for example, 1 second) when the engine 24 is in an operating state, The paddle shift management ECU 34 (vehicle 1) is set to the password change mode. When the paddle shift management ECU 34 is in the password change mode (registration pattern change mode), the password change unit 43 stores the operation procedure actually input through the paddle switches 4 and 5 as a new registered password Dk. Register with. When the new registration password Dk is correctly written in the memory 36, the password change unit 43 cancels the password change mode of the paddle shift management ECU 34 and returns it to the original normal state.

  Next, the detailed operation when changing the registered password Dk will be described with reference to the flowchart shown in FIG. The flowchart of FIG. 6 is executed on condition that the left and right paddle switches 4 and 5 are simultaneously operated during engine operation.

  In step 200, the lighting of the engine switch lamp 25 is switched from the orange lighting state to the orange blinking state, and the driver is notified that the paddle shift management ECU 34 (vehicle 1) has entered the password change mode. Note that the engine 24 at this time remains in an operating state.

In step 201, the numerical value input by the right paddle switch 4 is acquired as a numerical value in the thousands of the new password Dnw.
In step 202, it is determined whether or not the operation of the left paddle switch 5, that is, the operation of confirming the numeric input of the thousands place has been performed. Here, if the left paddle switch 5 is operated, the input numerical value at this time is acquired as a numerical value of the thousands of the new password Dnw, and the process proceeds to step 203. If the left paddle switch 5 is not operated, the input value is 1000. Continue to get the numeric input of the place.

In Step 203 and Step 204, the numerical value of the hundreds of the new input password is acquired in the same procedure as when the new password Dnw is the thousands.
In step 205 and step 206, the tenth digit value of the new password is acquired in the same procedure as when the new password Dnw is one thousand and one hundred.

In step 207 and step 208, the numerical value of the first digit of the new password is obtained by the same procedure as when the new password Dnw is 1,000, one hundred and ten.
In step 209, the buzzer 37 is sounded to notify the driver that the input operation of the new password Dnw has been completed.

  In step 210, it is determined whether or not the input operation of the new password Dnw is the second time. That is, in order to confirm whether or not the correct new password Dnw has been input in the password change operation, the new password input is performed twice, and it is determined whether or not the completion of the new password input at this time is the second time. . If the new password Dnw is input for the first time, the process returns to step 201 to input the new password Dnw again. If the new password Dnw is input for the second time, the process proceeds to step 211.

  In step 211, it is determined whether or not the first numerical value and the second numerical value of the password input work are the same. That is, it is confirmed whether or not a correct new password Dnw has been input in the password change operation. If the first and second values are the same, the process proceeds to step 212, and the first and second values are different. If there is, the process proceeds to step 214.

  In step 212, the lighting of the engine switch lamp 25 is returned from the orange blinking state to the orange lighting state, and the driver is notified that the input operation of the new password Dnw has been correctly completed.

In step 213, the four-digit numerical value from the thousands to the first digit input by the paddle switches 4 and 5 as described above is written in the memory 36 as the new registration password Dk.
In step 214, the engine 24 is stopped to end the password change mode, and the driver is notified that the new password Dnw has not been entered normally.

In step 215, the engine switch lamp 25 is switched from the orange blinking state to the extinguished state as the engine 24 is stopped.
Therefore, in this example, since the password change function is provided in the paddle shift management ECU 34, the registered password Dk in the memory 36 can be freely changed. For this reason, if the registered password Dk in the memory 36 is changed periodically, the registered password Dk does not need to become old, so that the vehicle theft can be further prevented from occurring. The registration password Dk is changed by actually operating the paddle switches 4 and 5 and registering the operation procedure at this time as a new password Dnw. For this reason, when changing the registered password Dk, there is no need to prepare a special tool dedicated to the change, which is also advantageous in this respect.

  The vehicle 1 is provided with a password notification function for notifying the user of the registration password Dk when the registration password Dk is forgotten. This password notification function will be described. As shown in FIG. 4, the paddle shift management ECU 34 is provided with a password notification 44 that operates when notifying the user of the registered password Dk on condition that personal authentication is established. This password notification 44 is also functionally generated by the CPU 35 of the paddle shift management ECU 34 and the password correctness determination program Ppr, and this is shown in a block diagram in FIG.

  The vehicle 1 is equipped with a car navigation system 45 that guides the driver to a destination when driving the vehicle. The car navigation system 45 originally has a function of destination guidance, but this example also operates as an input / output interface of a password notification function. In the car navigation system 45, a password notification application that is executed when operating as an input / output interface of the password notification function is registered, and the registered password Dk registered in the paddle shift management ECU 34 can be withdrawn. It is connected to the password notification 44 via wiring. The car navigation system 45 functions as an input interface for personal authentication required when permitting password notification, and also functions as an output interface for notifying an operator of a registered password after the personal authentication is established.

  The car navigation system 45 can be connected to an external communication system 47 such as a server or a G-Book via a wireless communication network 46 such as a wireless LAN, an Internet communication network, or a telephone communication network. The external communication system 47 functions as a master for overall management of the password notification function, and registered user data Dp1 is registered as personal information necessary for personal authentication. The registered user data Dp1 of the external communication system 47 includes a data group provided at the time of the use contract procedure of the external communication system 47, for example. When the external communication system 47 receives the input user data Dp2 input by the car navigation system 45, the external communication system 47 performs personal authentication by comparing the input user data Dp2 and the registered user data Dp1, and if this personal authentication is established, the vehicle Allow password notification at 1.

  Now, the detailed operation when notifying the driver who has forgotten the registration password Dk will be described. When an operation requesting execution of the password notification function is performed with various operation buttons of the car navigation system 45, FIG. As described above, the display 48 of the car navigation system 45 displays the user data input screen 49 for inputting user data necessary for personal authentication. The user data input screen 49 is provided with item fields 49a... For inputting various items such as address, nomination, age, date of birth, e-mail address, nickname and the like. The operator operates various operation buttons of the car navigation system 45 to input necessary items in the item column 49a... Of the user data input screen 49. When the input operation on the user data input screen 49 is completed, the car navigation system 45 transmits the data group input on this screen 49 to the external communication system 47 via the wireless communication network 46 as input user data Dp2.

  When the external communication system 47 acquires the input user data Dp2 from the car navigation system 45, the external communication system 47 performs personal authentication by comparing the input user data Dp2 with the registered user data Dp1 registered in itself. If the personal authentication is established, the external communication system 47 returns a password notification permission command Rp1 for permitting password notification in the vehicle 1 to the car navigation system 45. On the other hand, if the personal authentication is not established, the external communication system 47 A password notification disapproval command Rp2 for disabling password notification is returned to the car navigation system 45.

  When the car navigation system 45 receives the password notification permission command Rp1 from the external communication system 47, the car navigation system 45 recognizes that the password may be notified to the operator who has performed personal authentication at this time, and the registered password Dk is registered in the password notification 44. The transfer request is output. When the password notification 44 receives a transfer request for the registration password Dk from the car navigation system 45, the password notification 44 reads the registration password Dk in the memory 36 and transfers it to the car navigation system 45. When the car navigation system 45 receives the registered password Dk from the password notification 44, it displays it on its display 48. The operator inputs the registration password Dk displayed on the display 48 with the paddle switches 4 and 5 and starts the engine 24.

  On the other hand, when the car navigation system 45 receives the password notification non-permission command Rp2 from the external communication system 47, the car navigation system 45 recognizes that the operation that performed the personal authentication at this time is a third party, and sends a password notification to this person. Recognize not to go. When the car navigation system 45 recognizes that the operator who performed the personal authentication at this time is a third party, the car navigation system 45 displays an input user data error message on its own display 48 and operates that the registered password Dk cannot be notified. The person in charge.

  Therefore, in this example, since the vehicle 1 is provided with a password notification function, even if the registered password Dk is forgotten, the operator can be registered as long as the personal authentication given to the operator at the time of password notification can be accurately performed. It becomes possible to know the password Dk. For this reason, even if the registered password Dk is forgotten, the correct password input operation using the paddle switches 4 and 5 can be performed, and in this case, the engine 24 can be started without any problem. .

  Further, the paddle shift management ECU 34 is provided with a password invalidation function for invalidating the registered password Dk in the memory 36 when the number of erroneous password input operations exceeds the allowable number. Explaining this password invalidation function, the paddle shift management ECU 34 is provided with a password invalidation unit 50 that counts the number of mistakes in the password input operation and invalidates the registered password Dk when the number exceeds the threshold. The password invalidation unit 50 accumulates the number of mistakes of password input operations until the engine 24 is stopped and then becomes operational, and the number of mistakes exceeds a threshold (for example, three times). Is connected to the memory 36 in order to invalidate the registered password Dk. The password invalidation unit 50 is also functionally generated by the CPU 35 of the paddle shift management ECU 34 and the password correctness determination program Ppr. FIG. 4 is a block diagram of this.

  When the engine 24 is stopped, the password invalidation unit 50 monitors the number of mistakes in the password input operation, and increments the counter by one each time an incorrect operation is performed. Accumulate the number of times. Then, when the number of mistaken operations exceeds the threshold, the password invalidation unit 50 invalidates the registered password Dk written in the memory 36 so that the registered password Dk cannot be used. The invalidation mentioned here refers to, for example, processing for replacing the numerical value of the registered password Dk with a value not related to a numerical value such as a null value. When the vehicle 1 enters a running state (the vehicle speed becomes “0” or higher), the password invalidation unit 50 clears the number of mistakes accumulated so far and prepares for the next counting operation.

  Further, the vehicle 1 is provided with a password initialization function that enables an engine start operation after the registration password Dk is invalidated by the password invalidation function. Explaining this password initialization function, the paddle shift management ECU 34 is provided with a password initialization unit 51 for initializing the registered password Dk of the memory 36 in the invalidated state. The password initialization unit 51 is also functionally generated by the CPU 35 of the paddle shift management ECU 34 and the password correctness determination program Ppr. FIG. 4 is a block diagram of this.

  Furthermore, the car navigation system 45 functions not only as an input / output interface for a password notification function but also as an input / output interface for a password initialization function. In the car navigation system 45, a password initialization application that is executed when operating as an input / output interface of the password initialization function is registered, and a password initialization unit is connected via a cable or the like to perform this initialization operation. 51 is connected. The car navigation system 45 functions as an input interface for personal authentication required for password initialization, and also functions as an output interface for notifying the operator of the fact after the initialization is completed.

  Now, a detailed operation when initializing the invalidated registration password Dk will be described. When a password initialization function execution request operation is performed with various operation buttons of the car navigation system 45, the display 48 of the car navigation system 45 is displayed. Displays the same user data input screen as in the password notification function. When the operator inputs necessary items on the user data input screen and the input operation is completed, the input user data Dpx typed in at this time functions as a master for overall management of the password initialization function via the wireless communication network 46. To the external communication system 47.

  When the external communication system 47 acquires the input user data Dpx from the car navigation system 45, the external communication system 47 compares the input user data Dpx with the registered user data registered in itself and executes personal authentication. If this personal authentication is established, the external communication system 47 returns an initialization permission notification Rs1 permitting initialization of the invalidated registration password Dk to the car navigation system 45. On the other hand, if the personal authentication is not established. Returns an initialization disapproval notification Rs2 that disallows initialization of the invalidated registration password Dk to the car navigation system 45.

  When the car navigation system 45 receives the initialization permission notification Rs1 from the external communication system 47, it recognizes that the operator who has performed personal authentication at this time may permit the engine start, and initializes notification Rs1. Is transferred to the password initialization unit 51. Upon receiving the initialization permission notification Rs1 from the car navigation system 45, the password initialization unit 51 replaces the registered password Dk in the memory 36 with the initial password. As a result, the operator inputs the initial password with the paddle switches 4 and 5 and starts the engine 24. On the other hand, when the car navigation system 45 receives the initialization non-permission notification Rs2 from the external communication system 47, the car navigation system 45 recognizes that the operator who has performed personal authentication at this time is a third party, and informs the operator of that fact on the display 48. Notify the operator that the registered password could not be initialized.

  Therefore, in this example, since the password invalidation function for invalidating the registered password Dk is provided when the number of mistakes in the password input operation exceeds the allowable number, the thief temporarily enters the dark cloud during the theft. If the password is entered, the registered password Dk becomes invalid when the number of mistakes at this time exceeds the allowable number. By the way, if the registered password Dk is invalidated, the password verification itself using the paddle switches 4 and 5 cannot be performed, so that the start of the engine 24 is indirectly prohibited. Therefore, if a password invalidation function is incorporated in the vehicle 1, it is possible to further reduce theft of the vehicle.

  Even if the registration password Dk is invalidated because the number of mistakes in the password input operation exceeds the allowable number as described above, the password initialization function is provided in this example, so if this password initialization function is executed, This invalidated registration password Dk can be replaced with an initial password. Therefore, even if the number of mistakes exceeds the allowable number and the registered password Dk is invalidated, if the password initialization function is executed and the input operation is performed to replace the invalidated password with the initial password, there is no problem. 24 can be started.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) The engine start permission condition includes not only the in-vehicle verification of the key operation free system 7 but also whether or not the regular password is input with the paddle switches 4 and 5. As a result, even if the theft attempts to steal the vehicle, it is necessary not only to steal the portable device 8, but also to obtain the password entered by the paddle switches 4 and 5. More objects need to be stolen. Therefore, the theft of the theft is greatly killed, and the situation in which the vehicle 1 is subjected to the theft is reduced, so that the vehicle theft can be further prevented.

  (2) The input password Dps required for determining whether to start the engine is input using the paddle switches 4 and 5 that are used when the automatic transmission of the vehicle 1 is manually switched. For this reason, it is possible to use common parts for the password input of the input password Dps and the shift position switching input of the automatic transmission, so there is no need to prepare a different operation system for each of these inputs. The number of parts around the seat can be reduced.

  (3) The paddle shift management ECU 34 is provided with a password change function for changing the registered password Dk registered in the memory 36 to a different numerical value. Therefore, if the registration password Dk is periodically changed, the new registration password Dk is registered in the vehicle 1 each time. Therefore, the registration password Dk does not need to be old, and the vehicle theft can be further prevented.

  (4) When starting the engine 24, the driver first presses the engine switch 23 while depressing the brake pedal, and after this switch operation, the left and right paddle switches 4 and 5 are operated to input a password. If the input password Dps at this time is correct, an operation process of starting the engine 24 is performed. Therefore, even if a password input operation by the paddle switches 4 and 5 is included in the engine start permission condition, the engine switch 23 is operated until the engine 24 is started, and then the paddle switches 4 and 5 are used to enter the password. The engine 24 can be started by a series of operations that make it difficult to feel uncomfortable input.

  (5) Since there is a time limit on the input time (password input mode) for inputting the password with the paddle switches 4 and 5, if this input time is up, the password input operation is forcibly terminated and the password input state is changed. Do not take a situation where it lasts for a long time. Therefore, since it is not necessary to give a grace period for password entry to the theft, it is possible to further reduce theft of the vehicle.

  (6) The vehicle 1 is provided with a password notification function for teaching the registered password Dk to the driver who has forgotten the registered password Dk. As a result, even if the driver forgets the registration password Dk, the engine 24 can be started with the registration password Dk notified by this function. Therefore, since a response when the driver forgets the registered password Dk is achieved, the convenience of the system can be enhanced.

  (7) The paddle shift management ECU 34 is provided with a password invalidation function for invalidating the registered password Dk when the number of erroneous password input operations exceeds the allowable number. As a result, for example, if the thief tries to steal the vehicle and enters the input password Dps many times in the dark clouds, the registration password Dk is invalidated when the number of mistakes in the input operation exceeds the allowable number. Become. Therefore, in this case, the password verification itself cannot be executed, and in this state, the start of the engine 24 is indirectly prohibited. Accordingly, since it is difficult for a situation where the engine 24 is illegally started by the theft, it is possible to further reduce the vehicle theft.

  (8) The vehicle 1 is provided with a password initialization function for replacing the registered password Dk that has been invalidated by the password invalidation function with an initial password. Therefore, for example, even if the driver mistakenly enters the password input operation many times and the registered password Dk is invalidated, if the password initialization function is executed and the registered password Dk is replaced with the initial password, The engine 24 can be started without any problem. Therefore, since a response when the driver accidentally disables the registered password Dk is achieved, the convenience of the system can be improved.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
The password input by the paddle switches 4 and 5 is not necessarily limited to after the operation of the engine switch 23, and may be reversed. In short, the password input operation using the paddle switches 4 and 5 may be performed at any time, and the start condition of the engine may be the ID verification establishment of the key operation free system 7 and the regular password input by the paddle switches 4 and 5. That's fine.

The number of paddle switches 4 and 5 is not necessarily required to be a pair (two), but may be one on one side, or may be three or more.
The operation direction of the paddle switches 4 and 5 is not necessarily limited only to the pulling side, and may be capable of operating in the pushing direction opposite to the pulling direction. Further, the operation direction of the paddle switches 4 and 5 is not necessarily limited to only a straight line direction, and for example, a cross operation may be possible. In short, the operation direction of the paddle switches 4 and 5 is not particularly limited as long as it can be operated in at least one of the pulling direction and the pushing direction.

  -After pressing the engine switch 23, the engine start is permitted if the password verification performed by operating the paddle switches 4 and 5 is established. At this time, the engine start is started by the left and right paddle switches 4 , 5 are not limited to simultaneous operations. The start of the engine may be started, for example, when the password verification by the paddle switches 4 and 5 is established, or by re-operation of the engine switch 23.

-The password input of the paddle switches 4 and 5 is not limited to the method of verifying the numerical value for each position, and for example, a method of inputting a 4-digit numerical value at a time and verifying the numerical value may be used.
-The number of digits of the registered password Dk is not necessarily four digits, and this digit number can be changed as appropriate.

  -Password input by paddle switches 4 and 5 is not limited to entering numerical values from 0 to 9. This may be a combination of, for example, switch-on times for each time. For example, the first on-time is 5 seconds, the second on-time is 2 seconds, and the third on-time is 6 seconds. An example is given.

  The notification when the input password Dps matches the registered password Dk (including password verification for each rank) is not limited to display using the engine switch lamp 25. For example, it may be displayed visually on the instrument panel or may be sounded by the buzzer 37.

  ・ If a time limit is set for the password input time, this is not limited to viewing the entire input work (password input mode). For example, since password input is performed by entering multiple digits, a time limit is given when numerical values are entered, and when the input time at that time exceeds the time limit, password entry is terminated at that point. But you can.

  The password change function is not limited to a method of actually operating the paddle switches 4 and 5 and registering the operation procedure at that time as a new password Dnw. For example, a method may be used in which a dedicated change tool is used, the change tool is directly connected to the paddle shift management ECU 34, and the password input from the change tool is written in the memory 36.

  The start condition of the password change function is not limited to the simultaneous operation of the left and right paddle switches 4 and 5 when the engine is operating. For example, the paddle may be simply pressed for a long time, or the paddle may be operated from right to left (or vice versa) when the engine is running.

-The password change function may have a time limit as when entering a password.
The input / output interface for the password notification function and password initialization function is not necessarily limited to using the car navigation system 45. For example, an in-vehicle device other than the car navigation system 45 may be used, or an input / output interface dedicated to these functions may be provided.

  The functions of the paddle switches 4 and 5 are not necessarily limited to the shift conversion function, and may be used as an operation system of a cruise control system, for example. Further, when the shift position of the transmission is switched, the switching target is not limited to the automatic transmission, and may be a manually operated transmission, for example.

The key system is not limited to an electronic key system that uses an electronic key as a key, and may be a machine-operated key system that performs key verification using a mechanical key.
Next, technical ideas that can be grasped from the above-described embodiment and other examples will be described below together with their effects.

(1) In any one of the claims of the present invention, the time measuring means for measuring the time from when the determination means enters a determination mode in which the actual operation of the paddle type operation means is compared with the registered pattern, and the determination And ending means for forcibly terminating the determination mode when the time since the means has entered the determination mode exceeds a threshold value. According to this configuration, since the operation input of the paddle type operation means has a time limit, the operation input is forcibly terminated when the input time is up. Therefore, since the operation input by the paddle type operation means is not taken unnecessarily for a long time, the vehicle theft prevention effect can be further improved.

(2) In any one of the preceding Ko及 beauty the technical idea of the present invention (1), when a request operation for notifying the registration pattern to the user is performed in the vehicle, personal authentication imposing to the user at that time If is established, the registration pattern notification means for notifying the user of the registration pattern registered in the storage means via an in-vehicle device mounted on the vehicle is provided.
