Description

  The present invention belongs to the technical field of vehicles equipped with both an idle stop start system and a smart engine starter system.

  2. Description of the Related Art Conventionally, vehicles equipped with an idle stop start system are known for improving fuel efficiency, reducing exhaust emissions, preventing vibration and noise, and the like. For example, in the case of the vehicle disclosed in Patent Document 1, when the vehicle speed is zero and the foot is lowered from the clutch pedal, the engine is automatically stopped (idle stop), and when the clutch pedal is depressed in that state, the engine Are automatically started (idle start). In addition, when the engine stops automatically, power generation by an alternator, etc. stops and the remaining battery capacity decreases, so if the remaining battery capacity falls below a predetermined amount during automatic engine stop, It is known to start automatically. Similarly, when the engine automatically stops, the generation of negative pressure in the intake passage stops and the brake negative pressure decreases, so when the brake negative pressure drops below the predetermined negative pressure during automatic engine stop However, it is known that the engine is automatically started as an emergency response.

On the other hand, a vehicle equipped with a smart engine starter system is known to prevent theft of the vehicle. For example, in the case of the vehicle disclosed in Patent Document 2, wireless communication is performed between a vehicle-side transmission / reception device (on-vehicle device) mounted on the vehicle and a portable transmission / reception device (portable device) carried by an occupant. The engine is allowed to start when it is authenticated that the transmitted ID code is a legitimate ID code.

  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”. Assuming that the ID authentication of the portable device is established when the engine is automatically started by the ISS system, electromagnetic noise is generated if there is a broadcasting station near the vehicle (for example, if there is a broadcasting station near the vehicle, and wireless communication between the on-vehicle device and the portable device). If the mobile device is placed in the bag and placed in the corner of the vehicle interior, the request signal from the vehicle will not reach the mobile device. The wireless communication between the in-vehicle device and the portable device is affected), etc., the ID authentication of the portable device may fail, and the engine cannot be started automatically. 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. Even in such a case, in order to surely automatically start the engine, it is proposed to automatically start the engine without assuming the ID authentication of the portable device.

  On the other hand, as described above, when the occupant is taking a break with the switch of the on-vehicle electrical components such as the air conditioner and the audio turned on while the engine is automatically stopped by the ISS system in the parking area or the like, for example, In order to prevent the battery from discharging, it is necessary to automatically start the engine urgently. Similarly, for example, when an ISS system automatically stops the engine in a parking area or the like, If the brake negative pressure drops below a predetermined negative pressure while resting in the vehicle, it is necessary to automatically start the engine urgently in order to prevent the brake from becoming heavy.

  Then, despite the fact that the engine was automatically stopped by the ISS system, the occupant misunderstood that the engine stopped because he had stopped the engine, and went out of the car with his portable device. When the vehicle is gone, the engine is automatically started with no occupant in the vehicle. When someone else who does not carry the portable device is looking at the door, the door is unlocked and the occupant is not in the vehicle. However, it can be easily determined that the engine is in an auto-startable state, and it becomes a prey of theft, and the anti-theft performance by the SES system is significantly reduced.

  The present invention addresses the above-described problems and is for a vehicle that achieves both the prevention of theft prevention performance by the SES system and the smooth automatic start of the engine by the ISS system. An object is to provide an idle stop start control device.

  That is, in order to solve the above-mentioned problem, the invention according to claim 1 of the present application is a smart engine starter control means for permitting the engine start when the wireless portable device ID authentication is established during the engine start operation by the occupant. And an idle stop start control means for automatically starting the engine when the vehicle is stopped and at least when a predetermined emergency automatic start condition other than the vehicle starting operation is established other than when the vehicle starts operation is detected by the occupant. An idle stop start control device for a vehicle, comprising occupant detection means for detecting the presence of an occupant in the vehicle, wherein the idle stop start control means is not subject to the establishment of ID authentication of the portable device. The engine is allowed to start automatically, and the occupant is present in the vehicle by the occupant detection means. It is characterized in that it is configured to regulate the automatic starting of the engine when not detected.

  Next, according to a second aspect of the present invention, in the vehicle idle stop start control device according to the first aspect, the idle stop start control means operates the in-vehicle electrical component when the automatic engine start is restricted. It is characterized by restricting.

  According to a third aspect of the present invention, in the idle stop start control device for a vehicle according to the first or second aspect, the idle stop start control means may be configured such that an occupant is present in the vehicle by the occupant detection means. If not detected, automatic start of the engine is allowed on condition that ID authentication of the portable device is established.

  According to a fourth aspect of the present invention, in the idle stop start control device for a vehicle according to the second aspect, an occupant for operating the engine automatic start restriction and the in-vehicle electrical component operation restriction can be operated. A restriction release means is provided.

  First, according to the first aspect of the present invention, since automatic engine start is allowed without requiring the establishment of ID authentication of the portable device, even if a failure occurs in the ID authentication of the portable device. It is possible to automatically start the engine. In addition, when the presence of an occupant in the vehicle is not detected by the occupant detection means, the automatic engine start is restricted. Therefore, after the occupant gets off the vehicle while carrying the portable device, the occupant is absent. It is possible to improve the anti-theft performance by avoiding automatic starting of the engine.

  Next, according to the second aspect of the invention, when the automatic start of the engine is restricted, the operation of the on-vehicle electrical component is restricted, so that the battery is discharged in addition to improving the anti-theft performance. This can be prevented in advance.

  According to a third aspect of the present invention, when the presence of an occupant in the vehicle is not detected by the occupant detection means, automatic engine start is permitted on condition that ID authentication of the portable device is established. That is, since it is impossible to deny the possibility that a failure or detection error will occur in the occupant detection means, even if a failure or detection error occurs in the occupant detection means, the occupant will normally send the vehicle after waiting for a signal, etc. It is possible to avoid a problem that the engine does not start even though it has been operated. In addition, even if a malfunction or detection error occurs in the occupant detection means and it is not detected that the occupant is present in the vehicle, the engine is automatically activated when the identity verification of the portable device can be confirmed. Since the engine is started, it is possible to prevent the battery from being discharged and the in-vehicle electrical component from being suspended, and to prevent the brake negative pressure from being excessively reduced. In this case, even if the engine is automatically started, since the identity is confirmed, the vehicle is not stolen.

  According to the fourth aspect of the present invention, since the restriction release means operable by the occupant to release the restriction on the automatic start of the engine and the restriction on the operation of the in-vehicle electrical component is provided, the idle stop is being executed. When using an in-vehicle electrical component such as when an occupant goes out of the vehicle and uses the audio or uses a cable with a cigarette lighter outside the vehicle for a long period of time, use of the in-vehicle electrical component Is prevented reliably, and convenience can be improved.

  The vehicle interior motion sensor 18, the seating weight detection sensor 19, the electrical component unit 20, and the door opening detection sensor 26 correspond to “occupant detection means” recited in the claims.

  On the other hand, the portable device 50 carried by the passenger has a portable device control unit 51, a reception antenna 52, a transmission antenna 53, a lock switch 54, and an unlock switch 55. The portable device control unit 51 receives information from the reception antenna 52, the lock switch 54, and the unlock switch 55, outputs a control signal to the transmission antenna 53, receives the request signal from the in-vehicle device 40, The ID signal is transmitted to the machine 40. As shown in FIG. 1, the portable device 50 includes a battery 56 that is a drive source and an emergency key 57 that is used when the system fails.

  As shown in FIG. 3, when the request signal A is transmitted from the outdoor transmission antennas 33... 33, the area where 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 40 determines that the occupant X is outside the vehicle when the portable device 50, that is, the occupant X carrying the portable device 50, 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 33... 33 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 34, 34, areas where the request signal A reaches, that is, detection areas R4, R5 are formed at the front and rear of the vehicle interior. The The control unit 40 determines that the occupant X is in the vehicle when the portable device 50, that is, the occupant X carrying the portable device 50, 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 34 and 34 and the detection areas R4 and R5 in the vehicle 1, the wheels 2 ... 2, the driver's seat 3, the passenger seat 4, the rear seat 5, and the steering wheel 6 is also illustrated.

  Further, as shown in FIG. 5, the outdoor transmission antennas 33 and 33 arranged on 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 40 determines that the occupant X is in the vehicle when the portable device 50, that is, the occupant X carrying the portable device 50, 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 operation unit 10 is in the steering lock position (Lock), and its rotation operation is prevented. First, the occupant X presses the ignition operation unit 10. When receiving the pressing operation, the control unit 40 transmits a request signal A via the transmission antennas 33 and 34. When the portable device 50 carried by the passenger X receives the request signal A, the portable device 50 transmits an ID signal B including its own ID code. When the control unit 40 receives the ID signal B via the receiving antenna 35, the control unit 40 determines whether or not the ID code matches a regular ID code (performs ID authentication). Is established), the turning operation of the ignition operation unit 10 is permitted. When the occupant X rotates the ignition operation unit 10 to the steering lock release position (Off), the steering lock mechanism 11 is deactivated and the rotation of the handle 6 is mechanically permitted.

  Further, when the occupant X rotates the ignition operation unit 10 to the ignition start position (Start) (engine start operation), the control unit 40 transmits the request signal A again via the transmission antennas 33 and 34. When the portable device 50 carried by the occupant X receives the request signal A, the portable device 50 transmits again the ID signal B including its own ID code. When the control unit 40 receives the ID signal B via the receiving antenna 35, the control unit 40 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, an example of more detailed specific operations of the control unit 40 and the portable device 50 in the vehicle 1 will be described with reference to the flowchart of FIG.

  First, in step S1 of FIG. 7, the control unit 40 determines whether or not an IG start operation has been performed, that is, whether or not the ignition operation unit 10 has been rotated to the ignition start position (Start). When there is an IG start operation, a request signal A is transmitted in step S2. In step S11, the portable device 50 determines whether or not the request signal A has been received. When received, in step S12, an ID signal B including its own ID code is transmitted. Thereafter, the portable device 50 proceeds to the idle stop start control routine of step S13.

  On the other hand, the control unit 40 determines whether or not the ID signal B is received within a predetermined time in step S3. When it is received, in step S4, the ID signal B is collated, that is, it is determined whether or not the ID code matches the regular ID code. In step S5, it is determined whether or not the ID signal B can be collated. When the collation is completed, that is, when ID authentication of the portable device 50 is established, the engine is operated in step S6. Thereafter, the control unit 40 proceeds to the idle stop start control routine of step S7.

  In the above operation example, when the ignition operation unit 10 is rotated to the ignition start position (Start), the authentication of the ID signal B is performed in step S4. (1) When the ignition operation unit 10 is rotated from the steering lock release position (Off) to the accessory on position (Acc), (2) The ignition operation unit 10 is switched from the accessory on position (Acc) to the ignition on position. (3) When the predetermined time (for example, 3 seconds) elapses when the ignition operation unit 10 is in the accessory on position (Acc), (4) When the ignition operation unit 10 is turned to (On), (4) The ignition operation unit 10 is turned on. Every time a predetermined time (for example, 60 seconds) elapses in the position (On), (5) all Point A is one of the doors from being closed in open, or (6) when all doors are closed from either the door is open, may be performed preemptive.

  Next, the idle stop start control routine of steps S7 and S13 of FIG. 7 will be described with reference to the flowchart of FIG.

  First, the control unit 40 determines whether or not there is an IG stop operation in step S21 of FIG. When there is an IG stop operation, the engine is stopped in step S22 and the end is reached. On the other hand, when there is no IG stop operation, it is determined in step S23 whether or not idle stop is being executed. If it is being executed, it is determined in step S29 whether the remaining battery capacity is lower than the first predetermined amount. If it is not being executed, whether an idle stop condition is satisfied in step S24. Determine whether or not.

  Here, the idle stop condition is that the vehicle is stopped for a predetermined time or more, the parking brake is operated, the shift lever is located in a non-traveling range such as P range or N range, etc. is there.

  When the idle stop condition is satisfied in step S24, it is determined in step S25 whether the elapsed time from the previous automatic start exceeds a predetermined time. If it does not exceed, idle stop is not executed in step S26. In that case, the idle stop prohibiting lamp is turned on to notify the passenger X of that fact. Thereafter, the process returns to step S21. On the other hand, if it exceeds, an idle stop is executed in step S27. In that case, the idle stop lamp is turned on to notify the passenger X of that fact. Next, in step S28, the timer counter of the elapsed time from the automatic start is reset. Thereafter, the process returns to step S21.

  Further, in step S29, the control unit 40 determines whether or not the remaining battery capacity has decreased below the first predetermined amount. If the remaining battery capacity has decreased, the control unit 40 proceeds to step S40 in FIG. If the brake negative pressure has not decreased, it is determined in step S30 whether or not the brake negative pressure has decreased below the first predetermined negative pressure. And when it falls, it progresses to step S40 of FIG. 10, and when not falling, it progresses to step S31 of FIG. 9, and determines the presence or absence of vehicle start operation.

  Here, the vehicle start operation includes that the accelerator pedal is operated, that the parking brake is released, and that the shift lever is positioned in a travel range such as the D range or the R range.

  When there is a vehicle start operation in step S31, a request signal A is transmitted in step S32. In step S101, the portable device 50 determines whether the request signal A has been received. When received, in step S102, an ID signal B including its own ID code is transmitted.

  In step S33, the control unit 40 determines whether or not the ID signal B has been received within a predetermined time. When received, the ID signal B is verified in step S34. In step S35, it is determined whether or not the ID signal B can be collated. When the collation is completed, that is, when the ID authentication of the portable device 50 is established, the portable device 50 is placed in the vehicle interior in step S36. It is determined whether or not there is. As a result, when the vehicle is in the passenger compartment, the engine is operated in step S37. In step S38, the timer count of the elapsed time from the automatic start is started. Thereafter, the process returns to step S21. On the other hand, if NO in steps S33, S35, and S36, a take-out alarm for the portable device 50 is executed in step S39.

  Further, the control unit 40 determines whether or not the cancel switch is operated in step S40 of FIG. 10, and in step S41 when there is no operation, determines whether or not there is an occupant in the vehicle, and step when there is no occupant. In S42, the request signal A is transmitted. In step S103, the portable device 50 determines whether the request signal A has been received. When received, in step S104, an ID signal B including its own ID code is transmitted.

  Here, the cancel switch operation in step S40 is valid for a predetermined time and is valid until an IG stop operation is performed. In step S41, it is determined that there is an occupant in the vehicle when the door opening operation is not detected by the door opening detection sensor 26 from the start of the idle stop execution, or when the vehicle interior motion sensor 18 has a reaction. It is one of when the output of the weight sensor 19 is present and when the switch operation of the electrical component unit 20 is performed.

  Next, in step S43, the control unit 40 determines whether or not the ID signal B has been received within a predetermined time. When received, the ID signal B is verified in step S44. In step S45, it is determined whether or not the ID signal B can be collated. When the collation is completed, that is, when the ID authentication of the portable device 50 is established, the portable device 50 is placed in the vehicle interior in step S46. It is determined whether or not there is. As a result, when the vehicle is in the passenger compartment, the process proceeds to step S47 in FIG. 11 to operate the engine. In this case, when there is an operation restriction of electrical components in step S53 described later, the operation restriction is released. On the other hand, if NO in steps S43, S45, and S46, an alarm is issued in the vehicle for a predetermined time in step S51 of FIG. 11, and then the remaining battery capacity is set to a third predetermined amount (this third predetermined amount) in step S52. Is a value smaller than the first predetermined amount in step S29). When the voltage drops, the operation of the electrical component is restricted in step S53, and then the process returns to step S40 to determine whether or not the cancel switch is operated. On the other hand, if the voltage does not drop, the process returns to step S40 in the same manner. It is determined whether or not the cancel switch is operated.

  In step S47 of FIG. 11, the engine is operated, and then in step S48, it is determined whether there is a vehicle start operation. If there is no vehicle start operation, it is determined in step S49 whether there is an IG stop operation. When there is an IG stop operation, in step S50, the engine is stopped and the end. On the other hand, when there is no IG stop operation, it is determined in step S54 whether the remaining battery capacity is equal to or less than a second predetermined amount. If not, it is determined in step S55 whether or not the brake negative pressure has decreased below a second predetermined negative pressure (this second predetermined negative pressure is higher than the first predetermined negative pressure in step S30). If it has not decreased, after executing idle stop in step S56, the process returns to step S31 in FIG. Similarly, when there is a vehicle start operation in step S52, the process returns to step S31. Further, when YES is obtained in steps S54 and S55, the process returns to step S40 in FIG.

  Thus, in this embodiment, in the vehicle 1 having both the ISS system and the SES system, the vehicle interior motion sensor 18, the seating weight detection sensor 19, the switch of the electrical component unit 20, When the occupant detection means such as the door open detection sensor 26 detects that the occupant X is present in the vehicle (step S41), the automatic start of the engine is permitted without being conditional on the ID authentication of the portable device 50 being established. Therefore, even if a failure occurs in the ID authentication of the portable device 50 (step S47), the engine can surely be automatically started if there is a passenger X in the vehicle.

  Further, the presence of the occupant X in the vehicle is not detected by the occupant detection means 18, 19, 20, 26... (Step S41), and the portable unit is transmitted within a predetermined time after the control unit 40 transmits the request signal A. When the ID signal B is not received from 50 (step S43), or when the ID signal B is received but cannot be verified (step S45), or when the portable device 50 is not present in the passenger compartment (step S46), a notification lamp And the buzzer 28 issue a warning in the vehicle for a predetermined time (step S51), and the automatic start of the engine is restricted (there is no engine operation routine as in step S47), so the occupant X carries the portable device 50. After getting off the vehicle, the SES system prevents the engine from being automatically started in the absence of the occupant X. It is possible to improve the prevention performance.

  Further, when the automatic start of the engine is restricted, the operation of the on-vehicle electrical components is restricted (step S53), so that the battery is prevented from discharging in addition to improving the anti-theft performance. It becomes possible. In this case, step S52 can be omitted.

  When the occupant detection means 18, 19, 20, 26,... Do not detect that the occupant X is present in the vehicle (step S41), the automatic engine start is permitted on condition that the ID authentication of the portable device 50 is established. (Step S47). That is, since it is impossible to deny the possibility of a failure or detection error of the occupant detection means 18, 19, 20, 26 ..., for example, a failure or detection error occurs in the occupant detection means 18, 19, 20, 26 ... Even in this case, it is possible to avoid a problem that the engine does not start even though the passenger X himself / herself normally performs a vehicle transmission operation after waiting for a signal or the like. Further, even if the occupant detection means 18, 19, 20, 26, etc. have a failure or a detection error and it is not detected that the occupant X is present in the vehicle, the ID authentication of the portable device 50 is established. When the identity is confirmed, the engine is automatically started, so the battery is discharged and the in-vehicle electrical components are prevented from being suspended, and the brake negative pressure is prevented from excessively decreasing. It becomes possible to prevent. In this case, even if the engine is automatically started, since the identity is confirmed, the vehicle is not stolen.

  And since the cancel switch 21 which cancels the restriction | limiting of the engine automatic start by the control unit 40 and the operation | movement regulation of vehicle-mounted electrical equipment is provided, when the passenger | crew X uses this cancel switch 21, an engine will operate | move (step). S47). As a result, when the occupant X goes out of the vehicle during the idle stop, the occupant X uses, for example, audio outside the vehicle for a long period of time or uses a cable using a cigar lighter. During use, the use of these in-vehicle electrical components is surely prevented, and convenience can be improved.

  As described above in detail with reference to specific examples, according to the present invention, both the prevention of the anti-theft performance of the SES system and the smooth start of the automatic engine start of the ISS system can be achieved. Can do. The present invention has wide industrial applicability in the technical field of vehicles with both ISS and SES systems.
