  By the way, the following problems may occur in a vehicle including both the idle stop start system and the smart engine starter system as described above. Hereinafter, the idle stop start is abbreviated as “ISS”, and the smart engine starter system is abbreviated as “SES”. That is, when the engine is automatically started by the ISS system, as in the case of the SES system, if the ID authentication of the portable device is established, electromagnetic noise is generated if there is a broadcasting station (for example, a broadcasting station beside the vehicle). Affects the wireless communication between the in-vehicle device and the portable device) or the place of the portable device in the vehicle interior (for example, if the portable device is placed in a bag and placed in the corner of the vehicle interior) The request signal does not reach the portable device, which affects the wireless communication between the in-vehicle device and the portable device), or the degree of battery consumption of the portable device (for example, if the degree of battery consumption of the portable device is large, the ID signal from the portable device The engine cannot be automatically started when a failure occurs in the ID authentication of the portable device due to, for example, the radio wave intensity weakening and affecting the wireless communication between the in-vehicle device and the portable device. Therefore, for the passenger, the engine is automatically stopped on the vehicle side, and this time the engine does not automatically start when starting, so for example, only one vehicle cannot start at the intersection, which hinders traffic. And you will be panicked.

  On the other hand, in order to solve the above problem, if it is not necessary to establish the ID authentication of the portable device when the engine is automatically started by the ISS system, the occupant misunderstands the automatic stop of the engine in a parking area, for example ( Misunderstood that the engine has stopped because the engine has been stopped), and even if the person who does not carry the portable device gets out of the car and steps on the clutch pedal, etc. Since the engine is automatically started, the anti-theft performance by the SES system is significantly reduced.

  The present invention copes with the above-described problems, and is a vehicle idle system that achieves both automatic start of an engine smoothly by an ISS system without hindrance and prevention of deterioration of the anti-theft performance by an SES system. It is an object to provide a stop start control device.

  That is, in order to solve the above-mentioned problem, the invention according to claim 1 of the present application performs ID authentication of a portable device carried by the occupant when the occupant starts the engine, and when the ID authentication of the portable device is established, Smart engine starter control means for permitting the start and prohibiting the start of the engine when the portable device ID authentication is not established; and when the predetermined automatic stop condition is satisfied, the engine is automatically stopped, and the predetermined automatic start condition is An idle stop start control device for a vehicle comprising an idle stop start control means for automatically starting the engine when established, wherein the idle stop start control means is provided on the outside of the portable device when the predetermined automatic start condition is established. When the possibility of taking out is determined, and it is determined that there is no possibility of taking out, the establishment of ID authentication of the portable device is not a condition Engine is automatically actuated, when it is determined that the possibility of taking out is present characterized in that it is configured to automatically start the engine under a condition establishment of ID authentication of the portable device.

  Next, according to a second aspect of the present invention, there is provided the vehicle idle stop start control device according to the first aspect, wherein the idle stop start control means is a predetermined opening / closing body that partitions the vehicle interior and the exterior of the vehicle. The possibility of taking the portable device out of the vehicle is determined according to the open / closed state of the mobile phone.

  Next, the invention according to claim 3 is the idle stop start control device for a vehicle according to claim 2, wherein the idle stop start control means opens and closes a predetermined opening / closing body of the vehicle while the engine is automatically stopped. When it is operated, ID authentication of the portable device is performed at that time, and when ID authentication of the portable device is established, there is no possibility of taking the portable device out of the vehicle in the determination when the predetermined automatic start condition is satisfied It is characterized by determining.

  According to a fourth aspect of the present invention, in the idling stop start control device for a vehicle according to the second aspect, the idling stop start control means opens and closes a predetermined opening / closing body of the vehicle while the engine is automatically stopped. When the ID authentication of the portable device is not established, it is determined that the portable device may be taken out of the vehicle, and a predetermined warning is immediately given. And

  First, according to the first aspect of the present invention, in a vehicle having both the ISS system and the SES system, it is determined whether or not the portable device is taken out of the vehicle when the engine is automatically started. If it is determined whether the occupant carrying the vehicle has gone out of the vehicle or is in the vehicle, and as a result, it is determined that the portable device has not been taken out of the vehicle, the condition is that the ID authentication of the portable device has been established. Since the engine is automatically started without any trouble, the problem that the ID authentication failure of the portable device occurs during the automatic start of the engine and the engine cannot be automatically started is avoided. In this case, since an occupant carrying the portable device is in the vehicle, the anti-theft performance is not deteriorated even if the engine is automatically started without the requirement for the ID authentication of the portable device.

  On the other hand, when it is determined that the portable device has been taken out of the vehicle during the automatic engine start, the engine is automatically started on the condition that the ID authentication of the portable device is established. Even if a person who does not take a ride aiming at the absence of a passenger carrying the portable device, the engine is not automatically started, and the anti-theft performance is surely ensured.

  Next, according to the second aspect of the present invention, a predetermined opening / closing body that separates the vehicle interior and the exterior of the vehicle, such as a door, a window, or a rear hatch that is opened / closed when a passenger enters / exits, is opened / closed. Since the possibility of taking the portable device out of the vehicle is determined based on the fact, the determination as to whether or not the portable device has been taken out of the vehicle is made reasonably and accurately.

  Next, according to the invention described in claim 3, when the door or window is opened and closed during the automatic stop of the engine, ID authentication of the portable device is performed in advance at that time, and as a result, When the ID authentication of the portable device is established, it is determined that the portable device has not been taken out of the vehicle when the engine is automatically started. Therefore, erroneous determination that the portable device is being taken out of the vehicle is avoided.

  According to the fourth aspect of the present invention, when the door or window is opened / closed while the engine is automatically stopped, the portable device ID is authenticated at that time, and as a result, the portable device ID is obtained. When the authentication is not established, it is determined that the portable device has been taken out of the vehicle, and a predetermined warning is immediately given. For example, it is assumed that the user has stopped the engine while the engine is automatically stopped. It is possible to alert a passenger who is going out of the vehicle with the portable device. Hereinafter, the present invention will be described in more detail through the best mode for carrying out the invention.

  The control unit (on-vehicle device) 100 corresponds to “smart engine starter control means” and “idle stop start control means” according to claim 1.

  As shown in FIG. 2, the control unit 100 functioning as an in-vehicle device inputs information from the ignition knob 10, the door request switch 112 and the receiving antenna 133, and the ignition knob 10, the door lock actuator 116, and the meter unit 117. The control signal is output to the vehicle outside buzzer 118, the outdoor transmission antenna 131, and the indoor transmission antenna 132. In addition, the control unit 100 includes a brake pedal sensor (detecting the depression amount of the brake pedal) 101, a vehicle speed detection sensor 102, an inhibitor switch (turned on when the shift lever is in the non-traveling range) 103, a parking brake switch 104. , Air conditioner switch 105, engine water temperature sensor 106, turn signal switch 107, road surface gradient sensor 108, throttle opening sensor 109, steering angle sensor 110, engine rotation sensor 111, door opening detection sensor (driver seat door, passenger seat door, rear seat Detecting that the door or rear hatch is in an open state: Note that other opening / closing bodies of the vehicle 1, for example, a window open detection sensor for detecting that a window is in an open state can also be used) 113 and a door lock detection sensor (Driver seat door, passenger seat door Detecting that the rear seat door or the rear hatch is closed and the door is locked: a window closing detection sensor for detecting that the other opening / closing body of the vehicle 1, for example, the window is closed is used. The control signal is input to the fuel injection valve 120 via the driver 119, and the control signal is output to the spark plug 122 via the ignition coil 121.

  On the other hand, the portable device 200 carried by the occupant has a portable device control unit 201, a reception antenna 202, a transmission antenna 203, a lock switch 204, and an unlock switch 205. The control unit 201 inputs information from the reception antenna 202, the lock switch 204, and the unlock switch 205, and outputs a control signal to the transmission antenna 203, thereby receiving a request signal from the in-vehicle device 100. The ID signal is transmitted to the in-vehicle device 100. As shown in FIG. 1, the portable device 200 includes a battery 206 as a drive source and an emergency key 207 for use during a system failure or the like.

  As shown in FIG. 3, when the request signal A is transmitted from the outdoor transmission antennas 131... 131, the areas to which the request signal A arrives, that is, the detection areas R1, R2, and R3 are the driver's seat door, the passenger seat door, and the rear hatch. It is formed in the vicinity. The control unit 100 determines that the occupant X is outside the vehicle when the portable device 200, that is, the occupant X carrying the portable device 200 is detected in at least one of the detection areas R1, R2, and R3. The illustrated example shows a case where an occupant X is detected in the detection area R1 near the driver's seat door. 3 clearly shows the arrangement of the outdoor transmission antennas 131... 131 and the detection areas R1, R2, and R3 in the vehicle 1, the wheels 2... 2, the driver seat 3, the passenger seat 4, and the rear seat 5. The handle 6 is also illustrated.

  Further, as shown in FIG. 4, when the request signal A is transmitted from the indoor transmission antennas 132 and 132, areas where the request signal A reaches, that is, detection areas R4 and R5 are formed at the front and rear of the vehicle interior. The The control unit 100 determines that the occupant X is in the vehicle when the portable device 200, that is, the occupant X carrying the portable device 200 is detected in at least one of the detection areas R4 and R5. The illustrated example shows a case where an occupant X seated in the driver's seat 3 is detected in the detection area R4 in the front part of the passenger compartment. Also in FIG. 4, in order to clearly show the arrangement of the indoor transmission antennas 132 and 132 and the detection areas R4 and R5 in the vehicle 1, wheels 2 ... 2, a driver's seat 3, a passenger seat 4, a rear seat 5, and a steering wheel 6 is also illustrated.

  Furthermore, as shown in FIG. 5, the outdoor transmission antennas 131 and 131 arranged in the driver's seat door and the passenger seat door can enlarge the detection areas R11 and R12, and the detection areas R11 and R12 overlap. The area almost covers the interior space of the vehicle. The control unit 100 determines that the occupant X is in the vehicle when the portable device 200, that is, the occupant X carrying the portable device 200, is detected in the detection areas R11, R12, that is, in the overlap region.

  Next, the operation of the SES system in the vehicle 1, that is, the operation when the occupant starts the engine will be outlined with reference to FIG. As described above, when the engine is started, the ignition knob 10 is in the steering lock position (Lock) and its rotation operation is prevented. First, the passenger X presses the ignition knob 10. When receiving the pressing operation, the control unit 100 transmits a request signal A through the transmission antennas 131 and 132. When the portable device 200 carried by the occupant X receives the request signal A, the portable device 200 transmits an ID signal B including its own ID code. When the control unit 100 receives the ID signal B via the receiving antenna 133, the control unit 100 determines whether or not the ID code matches a regular ID code (performs ID authentication). When the above is established), the turning operation of the ignition knob 10 is allowed. When the occupant X rotates the ignition knob 10 to the steering lock release position (Off), the steering lock mechanism 11 is deactivated and the handle 6 is mechanically allowed to rotate.

  Furthermore, when the occupant X rotates the ignition knob 10 to the ignition start position (Start) (engine start operation), the control unit 100 transmits the request signal A again via the transmission antennas 131 and 132. When the portable device 200 carried by the occupant X receives the request signal A, the portable device 200 transmits the ID signal B including its own ID code again. When the control unit 100 receives the ID signal B via the receiving antenna 133, the control unit 100 determines again whether or not the ID code matches the normal ID code (performs ID authentication). When the authentication is established), the engine is allowed to start (engine start control).

  Next, the cooperation between the operation of the SES system and the operation of the ISS system in the vehicle 1 will be outlined with reference to the flowchart of FIG. First, as an SES function, if there is an engine start operation in step S1, ID authentication of the portable device 200 is performed in step S2, and the engine enters an operating state in step S3 only when ID authentication is established. Thereafter, as an ISS function, when an automatic engine stop condition (idle stop condition) is established in step S4, the engine is automatically stopped in step S5. Next, when the engine automatic start condition (idle start condition) is established in step S6, the doors of the vehicle 1 (driver seat door, front passenger seat door, rear seat door) during the engine automatic stop (idle stop) in step S7. It is determined whether or not the rear hatch has been opened. If the rear hatch has not been opened, the process returns to step S3 and the engine enters the operating state. On the other hand, when it is in the open state in step S7, ID authentication of the portable device 200 is performed in step S8, as in step S2, and the engine is in operation in step S3 only when ID authentication is established. .

  Here, for example, as shown in FIG. 8, the idling stop conditions in step S4 are as follows: (1) The vehicle speed is substantially zero (vehicle speed detection sensor 102); (2) The road surface gradient is ascending / descending. Both are smaller than a predetermined value (road surface gradient sensor 108), (3) the steering angle is smaller than a predetermined value (steering angle sensor 110), that is, not waiting for a right turn, and (4) the engine water temperature is higher than a predetermined value ( Engine water temperature sensor 106), (5) Even if the air conditioner is off or the air conditioner is on, the deviation between the target temperature and the actual temperature is not more than a predetermined value (air conditioner switch 105), that is, the electric load on the engine is small, Is set. Further, as an auxiliary condition, the parking brake is operated (parking brake switch 104) and the shift lever is operated to the non-traveling range (inhibitor switch 103) is set. Here, the idle stop condition is satisfied when all the preconditions (1) to (5) are satisfied and the auxiliary condition is satisfied.

  Further, for example, as shown in FIG. 9, the idling start conditions in step S6 are as follows: (1) A state where the vehicle speed is greater than a predetermined value has continued for a predetermined time (vehicle speed detection sensor 102); (2) The steering angle has changed (steering angle sensor 110), (3) the engine water temperature is higher than a predetermined value (engine water temperature sensor 106), and (4) the air conditioner has been operated from off to on (air conditioner switch 105). That is, it is set that the electrical load of the engine has increased, and (5) the winker has been operated from off to on (winker switch 107). Further, as an auxiliary condition, the parking brake is released (parking brake switch 104) or the shift lever is operated to the travel range (inhibitor switch 103) is set. Here, the idle start condition is satisfied when at least one of the preconditions (1) to (5) is satisfied or the auxiliary condition is satisfied.

  As a control operation that the control unit (on-vehicle device) 100 and the portable device 200 of the vehicle 1 proceed while performing wireless communication, as shown in FIG. 10, a door lock control routine (steps S11 and S21: SES system). ), An engine start control routine (steps S12 and S22: operation of the SES system), and an idle stop start control routine (steps S13 and S23: operation of the ISS system). These routines are repeatedly executed in order. The

  The door lock control routine in steps S11 and S21 is performed according to the flowchart shown in FIG. First, on the control unit (vehicle equipment) 100 side, it is determined in step S31 whether or not there is engine rotation (engine rotation sensor 111). If there is no engine rotation, the door request switch 112 is turned on in step S32. It is determined whether or not an operation has been performed. As a result, when the door request switch 112 is operated, in step S33, the request signal A is transmitted outside the vehicle interior (transmission antennas 131 and 132). In step S41, the portable device 200 determines whether or not the request signal A has been received (reception antenna 202). If received, the ID signal B including its own ID code is received in step S42. Is transmitted (transmitting antenna 203).

  Next, on the side of the control unit 100, it is determined in step S34 whether or not the ID signal B has been received within a predetermined time (reception antenna 133). Authentication is performed (that is, whether or not the ID code matches the regular ID code). As a result, when the ID signal B can be authenticated in step S36, that is, when the ID authentication of the portable device 200 is established, it is determined in step S37 whether or not the portable device 200 is outside the vehicle compartment (FIG. 3), when the vehicle is outside the passenger compartment, in step S38, depending on the current state of the door lock (door lock sensor 114), for example, if the door lock is not in operation, the door lock is activated (vehicle 1). On the contrary, if the door lock is currently in operation, the door lock is released (when returning to the vehicle 1).

  Further, the engine start control routine in steps S12 and S22 of FIG. 10 is performed according to the flowchart shown in FIG. 12 (see FIG. 6). First, on the side of the control unit (vehicle equipment) 100, in step S51, it is determined whether or not there is an engine start operation, that is, whether or not the ignition knob 10 has been turned to the ignition start position (Start). When there is an operation, the request signal A is transmitted in step S52 (indoor transmission antenna 132: see FIG. 4 or / outdoor transmission antenna 131: see FIG. 5). In step S61, the portable device 200 determines whether the request signal A has been received (reception antenna 202). If received, the ID signal B including its own ID code is received in step S62. Is transmitted (transmitting antenna 203).

  Next, on the control unit 100 side, in step S53, it is determined whether or not the ID signal B is received within a predetermined time (reception antenna 133). Authentication is performed (that is, whether or not the ID code matches the regular ID code). As a result, when the ID signal B can be authenticated in step S55, that is, when the ID authentication of the portable device 200 is established, engine start control is performed in step S56 (that is, engine start is allowed).

  In this example of operation, when the ignition knob 10 is rotated to the ignition start position (Start), the ID signal B is authenticated in step S54. (1) When the ignition knob 10 is rotated from the steering lock release position (Off) to the accessory on position (Acc), (2) the ignition knob 10 is moved from the accessory on position (Acc) to the ignition on position. (3) When a predetermined time (for example, 3 seconds) elapses while the ignition knob 10 is in the accessory-on position (Acc), (4) the ignition knob 10 is moved to the ignition-on position ( On), every time a predetermined time (for example, 3 seconds) elapses, (5) all Point A is one of the door from being closed in open, or (6) at the time that all the doors are closed from one of the state in which the door is open, may be carried out taking ahead.

  Then, the idle stop start control routine in steps S13 and S23 of FIG. 10, which constitute the characteristic part of the present invention, is performed according to the flowcharts shown in FIGS. First, on the side of the control unit (vehicle equipment) 100, it is determined in step S71 whether or not the engine is in an operating state (see step S3 in FIG. 7). It is determined whether stop is being executed. As a result, when the engine is not being executed, it is determined in step S73 whether or not an idle stop condition (see FIG. 8) is established. It is determined whether or not a predetermined time T or more has elapsed. As a result, when it has not elapsed, the idle stop is not executed in step S75. In that case, the idle stop prohibiting lamp (meter unit 117) is turned on to notify the passenger X of that fact. Thereafter, the process returns to step S71. On the other hand, when the time has passed in step S74, an idle stop is executed in step S76. In that case, the idle stop lamp (meter unit 117) is turned on to notify the passenger X of that fact. Next, in step S77, the timer counter of the elapsed time since the idle start is reset. Thereafter, the process returns to step S71.

  When the idle stop is being executed in step S72, the possibility of taking out the portable device 200 to the outside of the vehicle (that is, whether the occupant X carrying the portable device 200 has gone out of the vehicle or is in the vehicle) in step S78. It is determined whether or not it is time to confirm. Here, the take-out confirmation timing is, for example, (1) every time a predetermined time (for example, 2 seconds) elapses when the door is in an open state, and (2) immediately after the door in the open state is closed. (For example, after 1 second) or (3) When a predetermined time (for example, 15 seconds) elapses when the door is in a closed state, it is determined that it is a confirmation timing.

  When it is the confirmation timing, the request signal A is transmitted in step S79 (transmission antennas 131 and 132). In step S101, the portable device 200 determines whether or not the request signal A has been received (reception antenna 202). If received, the ID signal B including its own ID code is received in step S102. Is transmitted (transmitting antenna 203).

  Next, on the control unit 100 side, in step S80, it is determined whether or not the ID signal B has been received within a predetermined time (reception antenna 133). Authentication is performed (that is, whether or not the ID code matches the regular ID code). As a result, when the ID signal B can be authenticated in step S82, that is, when the ID authentication of the portable device 200 is established, it is determined in step S83 whether or not the portable device 200 is in the vehicle interior (FIG. 4 or FIG. 5), when the vehicle is in the passenger compartment, it is determined in step S85 whether or not an idle start condition (see FIG. 9) is established. On the other hand, if any of the steps S80, S82, and S83 is NO, in step S84, a take-out alarm for the portable device 200 is executed (the meter unit 117 and the buzzer for vehicle 118), and then the process proceeds to step S85.

  If the idling start condition is not satisfied in step S85, the process returns to step S71. If the idling start condition is satisfied, it is determined in step S86 whether or not the door has been opened during idling stop. (Door open detection sensor 113), if not, the process proceeds to Step S95 as it is, but if there is, it is determined in Step S87 whether the door is now closed (Door lock detection sensor 114). ). As a result, when it is in the closed state, it is determined in step S88 whether or not ID authentication immediately after the door is closed (that is, the case of the confirmation timing for taking out the portable device 200 to the outside in step S78 described above). (If (2) corresponds), the process proceeds to step S95 as it is, but if not, the process proceeds to step S89 as in the case where the door is not closed in step S87. The request signal A is transmitted (transmitting antennas 131 and 132).

  Then, in step S103, the portable device 200 determines whether or not the request signal A has been received (reception antenna 202). If received, the ID signal B including its own ID code is received in step S104. Next, in step S90, the control unit 100 determines whether or not the ID signal B is received within a predetermined time (receiving antenna 133). In S91, the ID signal B is authenticated (that is, it is determined whether or not the ID code matches the regular ID code). As a result, when the ID signal B can be authenticated in step S92, that is, when the ID authentication of the portable device 200 is established, it is determined in step S93 whether or not the portable device 200 is in the vehicle interior (FIG. 4 or FIG. 5), when the vehicle is in the passenger compartment, an idle start is executed in step S95. In that case, the idle start lamp (meter unit 117) is lit for a predetermined time, and this is notified to the occupant X. Next, in step S96, a timer counter for the elapsed time since the idle start is started.

  On the other hand, if any of the steps S90, S92, and S93 is NO, in step S94, a take-out alarm for the portable device 200 is executed (the meter unit 117 and the buzzer for vehicle 118), and the process returns to step S71.

  The operation that directly proceeds from step S86 to step S95 corresponds to the operation when the “idle stop start control means” according to claim 1 determines that the portable device 200 is not taken out of the vehicle, The operation that proceeds from step S86 to step S95 via S87 to S93 corresponds to the operation when the “idle stop start control means” according to claim 1 determines that the portable device 200 is taken out of the vehicle. To do.

  Further, the operation of step S78 and the operations of steps S86 to S88 correspond to the operation of the “idle stop start control means”.

  The operation of proceeding from step S78 to step S85 via steps S79 to S83 and the operation proceeding directly from step S86 to S88 to step S95 are the operations of the “idle stop start control means” according to claim 3. Equivalent to.

  The operation that proceeds from step S78 to step S84 via step S82 corresponds to the operation of the “idle stop start control means”.

  As described above, in this embodiment, in the vehicle 1 having both the ISS system and the SES system, it is determined whether or not the portable device 200 is taken out of the vehicle when the engine is automatically started. When it is determined whether or not the passenger X carrying the vehicle has gone out of the vehicle or is in the vehicle and, as a result, it is determined that the portable device 200 has not been taken out of the vehicle, the ID authentication of the portable device 200 is established. Since the engine is automatically started without the above condition, the problem that the ID authentication failure of the portable device 200 occurs during the automatic engine start and the engine cannot be automatically started is avoided. In this case, since the occupant X carrying the portable device 200 is in the vehicle, the anti-theft performance may be reduced even if the engine is automatically started without requiring the ID authentication of the portable device 200 to be established. Absent.

  On the other hand, when it is determined that the portable device 200 has been taken out of the vehicle during the automatic start of the engine, the engine is automatically started on the condition that the ID authentication of the portable device 200 is established. Even if a person who does not carry 200 rides aiming at the absence of the occupant X carrying the portable device 200, the engine is not automatically started, and the anti-theft performance is ensured.

  Further, the outside of the portable device 200 is opened based on the opening / closing operation of a predetermined opening / closing body that partitions the vehicle interior and the exterior of the vehicle 1 such as a door, a window, or a rear hatch that is opened / closed when the occupant X enters and exits. Since the possibility of being taken out is determined, the determination as to whether or not the portable device 200 has been taken out of the vehicle is reasonably and accurately determined.

  Further, when the door or window is opened or closed while the engine is automatically stopped, ID authentication of the portable device 200 is performed in advance at that time, and as a result, when ID authentication of the portable device 200 is established. When the engine is automatically started, it is determined that the portable device 200 has not been taken out of the vehicle. For example, the portable device 200 is removed from the vehicle based on a simple opening / closing operation of a door or a window that does not involve the entry or exit of the occupant X. A misjudgment that it has been taken out is avoided.

  When the door or window is opened / closed while the engine is automatically stopped, ID authentication of the portable device 200 is performed at that time. As a result, when ID authentication of the portable device 200 is not established, Since it is determined that 200 has been taken out of the vehicle and a predetermined warning is immediately given, for example, the user has misunderstood that the engine has been stopped while the engine is automatically stopped, and the portable device 200 remains carried. Attention can be given to crew member X who is about to go out of the vehicle.

  The above embodiment is the best embodiment of the present invention, but it goes without saying that various modifications and changes can be made without departing from the scope of the claims.

  As described above in detail with reference to specific examples, according to the present invention, the automatic start of the engine by the ISS system can be performed smoothly without any trouble and the deterioration of the anti-theft performance by the SES system can be achieved. . The present invention has wide industrial applicability in the technical field of vehicles with both ISS and SES systems.
