This will be described with reference to the flowchart shown in FIG.

In step S ₁ of the flowchart of FIG. 10, the control circuit 65 is initialized. In step S ₂ , signals from various sensors are input.
Described above in step _{S 3 (I), (II} ), is made as passenger boarding determination for each seat in a manner of (III).

If it is determined in step S _{3 that} the occupant is in the driver's seat 1 and at least one of the other seats 2 to 4 in step S ₃ , step S ₄
It is determined whether or not an emergency signal (for example, a signal from the emergency switch 45 or a detection signal indicating that the accelerator opening is equal to or more than the predetermined opening) is input. Here, if an affirmative determination is made, since emergency occurs, the process proceeds to step S ₂₀ to be described later, already when the engine output restriction is performed, immediately regulated released by the action of the second restriction release unit 659. The emergency switch 45
In the case of emergency signal output by N operation, the emergency switch 45
Is automatically turned off after a lapse of a predetermined time (for example, 6 hours).

If a negative determination is made in step S ₄ , it is determined in step S ₅ whether the occupant of the driver's seat 1 (ie, the driver) is wearing the seat belt 5 (in other words, the seat belt sensor 27 it is determined whether or not) there is a signal input made from, where negative (i.e., when the seat belt is not mounted as determined) has been the presence of normal running flag F ₂ in step S ₆ (i.e., normal running when either unusual or during running) is determined, if it is determined that the time of non-normal running, it is determined whether the time of running early in the step S ₇ is performed.

The determination at the beginning of traveling is made by the detection unit 652 at the beginning of traveling. Specifically, a signal is output when the vehicle speed increases to a predetermined value (for example, 3 km / h → 5 km / h). The shift sensor 44 outputs a signal when the shift lever 9 is shifted from the P, N range to the D range.

[0076] affirmative (i.e., traveling the initial time and judgment) in step S ₇ when it is a predetermined from the message output device 47 is a first warning means in accordance with a command from the first alarm output unit 653 at step S ₈ Alert message
(For example, the "seat belt is limited vehicle speed for not mounted") is output, and then proceeds to step S _9. Note that negative (i.e., during non-traveling initial and determination) at step S ₇ when been, the process proceeds to step S ₉ bypasses the step S _8. That is, the warning message is to be issued at the beginning of traveling.

In step S ₉ , the vehicle speed V is compared with the regulated speed Vs (for example, 20 km / h). If V ≧ Vs, the engine 46 is controlled in step S ₁₀ by a command from the engine output regulating means 651. Output regulation (for example, regulation to reduce the throttle valve opening by a predetermined amount) is performed,
V <is controlled to be Vs, the engine output restriction flag F ₁ in step S ₁₁ is set to 1. Although so as to compare the regulation vehicle speed Vs and the vehicle speed V at step S _9, the engine speed N and the restricting rotation speed Ns (e.g., 1500 rpm) and comparing, controlled to be N <Ns In some cases.

[0078] In this embodiment, at the same time step S ₁₂ the engine output restriction in step S _10, step S ₁₃ and step deactivation of the power steering device for a pump 19 in the S _14, the shift by the operation of the shift restricting device 39 lever 9 , And the OFF operation of the audio device switch 50 and the air conditioner switch 51 is performed. These may cause discomfort to the occupants of the vehicle, and thus promote the wearing of the seat belt. In this embodiment, the operation of the power steering device pump 19 is stopped, the operation of the shift lever 9 is controlled by the operation of the shift control device 39, and the audio device switch 50 and the air conditioner switch 51 are simultaneously turned off. However, there are cases where each of them is performed alternatively.

[0079] If it is determined that V <Vs in step S _9, the determination of whether or not the traffic jam traveling state in step S ₁₅ is performed. This traffic jam traveling determination is performed by the traffic jam traveling detecting means 654. Specifically, the vehicle speed V
= 0 to 10 km / h for more than 5 minutes is detected as traffic congestion, and the vehicle speed V is at least 10 km / h.
If it exceeds h, it will be considered as non-congested driving. Step S ₁₅
If it is determined that the traffic jam running in step S ₅
Second alarm output means in step S ₁₆ from where the driver is determined to seat belt not mounted at 65
The warning light 48, which is the second warning means, is turned on by a command from the driver 5, and the driver is prompted to wear the seat belt 5. The reason for performing this control is that the engine output is not regulated even if the occupant removes the seat belt during traffic congestion, so that it is necessary to notify the driver by turning on the warning light 48. If it is determined that the non-congested traveling in step S _15, as well as a degree need not to perform the engine output restricting vehicle speed (or engine speed),
Since there is little risk of a rear-end collision as in a traffic jam, step S
₁₆ is returned (in other words, without turning on the warning lamp 48).

[0080] On the other hand, an affirmative decision (i.e., the seat belt is worn and judgment) in step S ₅ when been the other occupants in step S ₁₇ (e.g., passenger, rear seat occupant or a child seat occupant) is a seat belt Is determined (in other words, the presence or absence of input signals from the seat belt sensors 27 to 30 and 37). Here, negative (i.e., the seat belt is not mounted and determination) if has been the automotive determination is made whether the time of starting in step S _18. If a positive result is obtained in this it does not perform the processing of the following steps S ₇ described above, the determination of whether the engine output restriction flag F ₁ = 1 at step S ₁₉ of FIG. 11 is made. During starting the process proceeds to F ₁ = 0 since steps S _20, the engine output restriction is released. The reason for performing such control is to take into account that, in the case of an occupant other than the driver, the seatbelt is not always worn at the same time as riding, and the seatbelt is often worn shortly after the vehicle starts. .

[0081] When the engine output restriction in step S ₂₀ is released, is reset to the engine output restriction flag F ₁ = 0, it is determined whether the normal running state is made in step S _22. The normal traveling determination is performed by the normal traveling detecting means 656, and specifically, the vehicle speed V
Is compared with the regulation speed Vs (for example, 20 km / h).
For Vs, it is determined that normal driving, in step S ₂₃ is set to the normal running flag F ₂ = 1, if the V ≦ Vs, it is determined that a non-normal traveling, F ₂ in step S ₂₄
= 0, then return.

[0082] When it is determined not to be at the start in step S _18, the process returns to step S _6, as if the driver seat belt is not mounted normal running flag F ₂ = 1
In it is determined whether or not is made, negative (i.e., non-normal running judged) when has been in the process of the following steps S ₇ described above is performed, an affirmative determination is made (i.e., determines that the normal running) If the in step S ₂₅ warning lamp 48 is lit, the process returns to step S ₂₀ subsequent Figure 11, the engine output restriction by the engine output restricting means 651 is released by the first restraint release means 657. By performing such control, even if the occupant removes the seat belt during normal driving (for example, when driving at a speed of 20 km / h or more), engine output restriction by the engine output restriction means 651 is not performed. As a result, rapid deceleration does not occur.

[0083] (in other words, if all passengers is determined to seat belt use) if it is determined that the other occupant also belted in step S _17, the step S ₁₈
The Bypass flow proceeds to step S ₁₉ in FIG. 11, determination of whether the engine output restriction flag F ₁ = 1 is made, in the case of F ₁ = 0, since everyone is wearing a seat belt because there, naturally engine output restriction by the engine output restricting means 651 in step S ₂₀ is released.

By the way, in step S ₁₉ , F ₁ = 1
(I.e., the engine output restriction) When it is determined that, if whether the determination (in other words whether the throttle valve in step S ₂₆ is actuated in the opening direction, whether the engine output is caused to increase Is determined). This determination is made by a signal input from a throttle valve opening sensor 43, an affirmative decision (i.e., determined that the throttle valve opening operation) when it is depends on the engine output restriction means 651 at step S ₂₇ The engine output regulation is maintained by a command from the regulation maintaining means 658, and thereafter, the process returns. As a result, even when the occupant wears the seat belt during the opening operation of the throttle valve, sudden acceleration is prevented since the engine output regulation is not released. Negative determination in step S ₂₆
(I.e., a determination throttle valve closing direction during operation) when it is, the process returns to step S _20, the engine output restriction is released.

Second Embodiment FIGS. 12 and 13 show a flowchart of a control circuit in a vehicle seatbelt use promotion device according to a second embodiment of the present invention. The present embodiment corresponds to the first , second, fourth to eighth aspects of the present invention.

[0086] In this embodiment, the alarm output step S ₁₈ in the flowchart of FIG. 10 (i.e., the lighting of the warning lamp 48) has been changed to the driver owed to wear seat belts, other passengers When the user does not wear a seat belt, only the warning light 48 is turned on, and the engine output is not regulated. In other words, there is a difference in regulation between the case where the driver does not wear the seat belt and the case where the other occupants do not wear the seat belt. The other configuration and operation and effect are the same as those of the first embodiment, and the description is omitted to avoid duplication.

Third Embodiment FIGS. 14 and 15 show a flowchart of a control circuit in an automobile seatbelt use promotion device according to a third embodiment of the present invention. The present embodiment corresponds to the first , second and fourth to eighth aspects of the present invention.

In the case of this embodiment, steps S ₅ ′ and S ₁₈ ′ are provided on the negative decision side of steps S ₅ and S ₁₈ in the flowchart of FIG. 10, respectively, to set the regulation speed Vs. For example Step S ₅ 'in Vs = 20km / h, the step S _18' is decided to a Vs = 40 km / h in. That is, there is a difference in the degree of engine output regulation between the case where the driver does not wear the seat belt and the case where the other occupant does not wear the seat belt. The other configuration and operation and effect are the same as those of the first embodiment, and the description is omitted to avoid duplication.

Fourth Embodiment FIGS. 16 and 17 show a flowchart of a control circuit in an automobile seatbelt promoting apparatus according to a fourth embodiment of the present invention. The present embodiment corresponds to the first , third to ninth aspects of the present invention.

In the case of the present embodiment, the control circuit 65 includes an engine output gradually decreasing means 657 'and an engine output gradually increasing means 658' instead of the first regulation canceling means 657 and the regulation maintaining means 658 (see FIG. 1). .

The engine output gradual increasing means 657 'is provided when the normal running detecting means 656 detects that the vehicle is in the normal running state, and the seat belt wearing detecting means (ie, the seat belt sensors 27 to 30, the child seat seat belt sensor). 37) has a function of gradually reducing the output of the engine 46 to a predetermined regulation value when it is detected that the seat belt is not worn.

The engine output gradually increasing means 658 '
Is a case where it is detected that the throttle valve is operated in the opening direction by the throttle valve opening sensor 43 acting as engine output detecting means (in other words, the engine output is increased), Seat belt wearing detecting means (that is, seat belt sensors 27 to 3)
0, when the seat belt is detected by the child seat seat belt sensor 37), the engine 46
Has a function of gradually increasing the output from a predetermined regulation value.

Next, the operation of the apparatus for promoting the wearing of a seat belt for an automobile according to this embodiment will be described with reference to FIGS.
This will be described with reference to the flowchart shown in FIG.

The control from step S ₁ to step S ₂₄ is the same as that in the first embodiment, so that the description will be omitted to avoid duplication.

If it is determined in step S ₁₈ that the vehicle is not starting, the process returns to step S ₆ , and the normal traveling flag F ₂ = 1 as in the case where the driver does not wear the seat belt.
In it is determined whether or not is made, negative (i.e., non-normal running judged) when has been in the process of the following steps S ₇ described above is performed, an affirmative determination is made (i.e., determines that the normal running) If the the warning lamp 48 is illuminated in step S _25, the process proceeds to step S ₂₆ subsequent Figure 17, the engine 4
It is determined whether the output value P of No. 6 is equal to the required output value P ₀ required by the throttle valve opening (that is, P = P ₀ ). If a negative determination is made here, step S ₂₇ At the engine 46 by the engine output gradually decreasing means 657 '.
Is gradually reduced by a predetermined amount, and then returns. Incidentally, if an affirmative determination is made in step S _26, there is no need for necessary engine output restriction of the engine output decreasing, the engine output restricting the flow returns to step S ₂₀ is released. By performing such control, during normal driving (for example,
Even when the occupant removes the seat belt at a speed of 0 km / h or more), the engine output is gradually reduced, so that rapid deceleration does not occur.

[0096] (in other words, if all passengers is determined to seat belt use) if it is determined that the other occupant also belted in step S _17, the step S ₁₈
The Bypass flow proceeds to step S ₁₉ in FIG. 17, determination of whether the engine output restriction flag F ₁ = 1 is made, in the case of F ₁ = 0, since everyone is wearing a seat belt because there, naturally engine output restriction by the engine output restricting means 651 in step S ₂₀ is released.

[0097] By the way, F ₁ = ₁ in step S ₁₉
(I.e., the engine output restriction) When it is determined that, if whether the determination (in other words whether the throttle valve in step S ₂₈ is actuated in the opening direction, whether the engine output is caused to increase Is determined). This determination is made by a signal input from a throttle valve opening sensor 43, an affirmative decision (i.e., determined that the throttle valve opening operation) when it is, the output value P of the engine 46 in step S ₂₉ Is equal to the required output value P ₁ required by the throttle valve opening (that is, P = P ₁ )
Been made of the determination, if a negative determination is made here, the output of the engine 46 by the engine output increasing means 658 'at step S ₃₀ is gradually increased by a predetermined amount, and then returns. Incidentally, if an affirmative determination is made in step S _29, there is no need for necessary engine output restriction of the engine output increasing engine output restricting the flow returns to step S ₂₀ is released. By performing such control, during the opening direction operation of the throttle valve (in other words, during the increase in engine output),
Even when the occupant wears a seat belt, the engine 46
Is to be gradually increased, so that sudden acceleration is prevented.

Other configurations, functions and effects are described in Embodiment 1.
