  ADVANTAGE OF THE INVENTION According to this invention, the noise at the time of a disposal process of the protection apparatus mounted in a vehicle can be reduced.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.
(First embodiment)
FIG. 1 is a block diagram showing an example of the system configuration of the vehicle operation control apparatus according to the first embodiment of the present invention. A vehicle operation control apparatus 10 according to the present embodiment is disposed in a vehicle interior, and is disposed outside a vehicle interior protection device (vehicle interior protection means) 1 that protects a passenger in the vehicle interior. During the disposal of the vehicle exterior protection device (vehicle exterior protection means) 2 that protects people etc. that come into contact with the outside such as the body, the vehicle interior protection device 1 and the vehicle exterior protection device 2, these devices 1 and 2 are forcibly used. ECU (operation control means) 3 to be operated.

  The vehicle interior protection device 1 includes, for example, a driver seat and passenger seat airbag device 1a, a driver seat and passenger seat knee airbag device 1b, a rear seat airbag device 1c, a side impact airbag device 1d, A curtain shield airbag device 1e and a seat belt pretensioner device 1f are included.

  The vehicle exterior protection device 2 includes, for example, a pedestrian protection airbag device 2a that deploys a pedestrian airbag when a pedestrian or the like collides with the outer surface of the vehicle and protects the pedestrian or the like.

  Each of the airbag devices 1a to 1e and 2a includes an airbag and inflators (gas generating units) 11a to 11e and 12a that generate gas to be introduced into the airbag and deployed. The print tensioner device 1f includes an inflator 11f that generates gas for retracting the seat belt, similarly to the airbag devices 1a to 1e. Each inflator 11a to 11f houses a gas generating agent that generates gas and squibs (ignition devices) 21a to 21f and 22a.

  The squibs 21 a to 21 f and 22 a are connected to the ECU 3 through the squib drive circuit 4. A vehicle power supply 5 is connected to the squib drive circuit 4. The vehicle power supply 5 supplies electric power to the squibs 21 a to 21 f and 22 a via the squib drive circuit 4. In addition, although the vehicle power supply 5 is connected to the squib drive circuit 4, an external power supply may be connected and power may be supplied from the external power supply to the squib drive circuit 4.

  The squib driving circuit 4 is composed of a switching element such as a field effect transistor or a bipolar transistor with good response. For example, when a vehicle collision occurs, the switching element of the squib drive circuit 4 switches from the off state to the on state when receiving a drive signal from the ECU 3. As a result, the squibs 21a to 21f and 22a of the airbag devices 1a to 1e and the pretensioner device 1f and the vehicle power supply 5 are energized. At this time, electric power is supplied to the squibs 21a to 21f and 22a, and the squibs 21a to 21f and 22a are ignited. By the ignition of the squib, the gas generating agent is ignited to generate gas. The gas generated from the gas generating agent is introduced into the airbag, and the airbag is deployed. Further, the seat belt is pulled in by the pressure of the gas generated from the gas generating agent.

  An ECU (Electronic Control Unit) 3 is composed of a microcomputer, executes various processes in accordance with control and arithmetic programs, and controls the CPU 3a for controlling each part of the device 10, and an execution program for the CPU 3a. It has a ROM 3b for storing, a readable / writable RAM (Random Access Memory) 3c for storing calculation results, a timer, a counter, an input / output interface (I / O) 3d, and the like.

  For example, when the disposal process of the vehicle is performed, the airbag apparatuses 1a to 1e and 2a and the pretensioner apparatus 1f mounted on the vehicle are not necessary. For this reason, in the disposal process of the vehicle, the squibs 21a to 21f and 22a of the airbag devices 1a to 1e and 2a and the pretensioner device 1f are forcibly ignited and the airbags of the airbag devices 1a to 1e and 2a are forcibly ignited. Further, it is preferable to dispose the product by operating the pretensioner device 1f.

  Therefore, the ECU 3 of the vehicle operation control device 10 has a forcible operation function for forcibly operating the airbag devices 1a to 1e, 2a and the pretensioner device 1f at the time of disposal of the vehicle.

  For example, a connector 6 may be provided between the squib drive circuit 4 and the vehicle power supply 5. When the dedicated tool 6a is connected to the connector 6, the forced operation function of the ECU 3 can be executed, and the above-described airbag devices 1a to 1e, 2a and the pretensioner device 1f are configured to be collectively activated. ing.

  The forced operation function of the ECU 3 is configured to be remotely executable by the user. For example, an operation signal is transmitted from the transmitter 7 located away from the vehicle to the ECU 3. When the ECU 3 receives the operation signal from the transmitter 7, the ECU 3 transmits a drive signal to the squib drive circuit 4 to forcibly operate the airbag devices 1a to 1e, 2a and the pretensioner device 1f.

  In addition, when the airbag device and the pretensioner device 1f are forcibly operated during the disposal process, noise is generated due to ignition of the squibs 21a to 21f and 22a, deployment of the airbag, and the like. Further, as described above, the pedestrian protection airbag device 2a disposed outside the vehicle compartment, and the airbag devices 1a to 1e and the pretensioner device 1f disposed in the vehicle interior are arranged in the vehicle. These devices 1a to 1f and 2a are all operated in series. For this reason, conventionally, there is a possibility that noise generated by each device is combined at the time of disposal and becomes loud noise.

  Therefore, in the vehicle operation control apparatus 10 according to the first embodiment, the pedestrian protection airbag apparatus 2a disposed outside the passenger compartment and the airbag apparatuses disposed in the passenger compartment during the disposal process. 1a to 1e and the print tensioner device 1f are operated with a time difference. Thereby, the noise which generate | occur | produces when each airbag apparatus 1a-1e, 2a and the pretensioner apparatus 1f act | operate can be generated shifting in time, and can be reduced.

  For example, the ECU 3 operates the airbag devices 1a to 1e or the pretensioner device 1f in the vehicle interior, and after the predetermined time T1 has elapsed from the start of the operation of the devices 1a to 1f, the pedestrian protection airbag device outside the vehicle interior. 2a may be activated.

  More specifically, the ECU 3 ignites the squibs 21a to 21f of the airbag devices 1a to 1e or the pretensioner device 1f in the vehicle interior, and after the predetermined time T1 has elapsed from the ignition of the squibs 21a to 21f, the ECU 3 The squib 22a of the pedestrian protection airbag device 2a may be ignited (FIG. 2A).

  As a result, as described above, the peak of the sound pressure level of the noise generated when each of the airbag devices 1a to 1e and the pretensioner device 1f in the vehicle interior is activated (FIG. 2B), and the pedestrian outside the vehicle interior. The peak of the sound pressure level of the noise generated when the protective airbag device 2a is activated (FIG. 2C) can be shifted in time. Note that the predetermined time (for example, about 2 seconds) T1 is experimentally determined and set for a time during which the sound pressure level of the previously generated noise is sufficiently reduced.

  Further, as described above, the peak of the sound pressure level of the noise generated by each of the devices 1a to 1f and 2a can be surely shifted. In this case, for example, when the vehicle interior protection device 1 is activated and the pressure inside the vehicle interior is rising, the vehicle exterior protection device 2 is activated and pressure is applied from outside the vehicle interior. Can be reliably prevented. Therefore, it can suppress that the glass crack of a vehicle interior generate | occur | produces.

  Next, a control processing flow of the vehicle operation control apparatus 10 according to the first embodiment will be described. FIG. 3 is a flowchart showing an example of a control processing flow of the vehicle operation control apparatus 10 according to the present embodiment.

  In a state where the dedicated tool 6a is connected to the connector 6, when the ECU 3 receives the operation signal from the transmitter 7, the ECU 3 starts executing the forced operation function of each of the airbag devices 1a to 1e, 2a and the pretensioner device 1f (S100). .

  The ECU 3 transmits a drive signal to the squib drive circuit 4 to ignite and operate the squibs 21a to 21f of the airbag devices 1a to 1e or the pretensioner device 1f in the vehicle interior (S110).

  Next, the ECU 3 determines whether or not a predetermined time T1 has elapsed after the ignition of the squibs 21a to 21f of the airbag devices 1a to 11e or the pretensioner device 1f in the vehicle interior (S120).

  When the ECU 3 determines that the predetermined time T1 has passed (Yes in S120), the ECU 3 transmits a drive signal to the squib drive circuit 4 to ignite and operate the squib 22a of the pedestrian airbag device 2a outside the vehicle compartment ( S130). On the other hand, when the ECU 3 determines that the predetermined time T1 has not elapsed (No in S120), the ECU 3 returns to the above (S120) process.

  As described above, in the vehicle operation control apparatus 10 according to the first embodiment, at the time of disposal, the pedestrian protection airbag apparatus 2a disposed outside the vehicle compartment and each airbag apparatus disposed in the vehicle interior. 1a to 1e and the print tensioner device 1f are operated with a time difference. Thereby, the noise generated when the airbag device 2a for protecting pedestrians outside the passenger compartment is activated and the noise generated when the airbag devices 1a to 1e and the pretensioner device 1f in the passenger compartment are activated. The noise can be reduced by shifting in time. That is, it is possible to reduce noise at the time of disposal of the protection devices 1 and 2 such as the airbag devices 1a to 1e and 2a and the pretensioner device 1f mounted on the vehicle.

  Next, a modification of the vehicle operation control apparatus 10 according to the first embodiment will be described.

  In the first embodiment, the pedestrian protection airbag device 2a may have a plurality of inflators 12a. In this case, the ECU 3 ignites the squibs 22a of the plurality of inflators 12a of the pedestrian protection airbag device 2a with a time difference.

  For example, the pedestrian protection airbag device 2a may have two inflators 12a. In this case, the ECU 3 ignites the squib 22a of one inflator 12a, and ignites the squib 22a of the other inflator 12a when a predetermined time T2 has elapsed since the ignition. Thereby, the noise at the time of operating the pedestrian protection airbag apparatus 2a which has the some inflator 12a at the time of a disposal process can be reduced.

  Further, the vehicle exterior protection device 2 is not limited to the pedestrian protection airbag device 2a, and can be applied to, for example, an active hood device that flips the hood upward by a lift-up mechanism using an inflator as a drive source. .

  In the first embodiment, the airbag apparatuses 1a to 1e and the pretensioner apparatus 1f in the vehicle compartment may be operated with a time difference.

  In the first embodiment, the ECU 3 operates the airbag device 2a for protecting pedestrians outside the vehicle interior, and after a predetermined time T3 has elapsed from the start of the operation of the device 2a, the airbag devices 1a to 1a in the vehicle interior. 1e or the pretensioner device 1f may be activated.

  In the first embodiment, the ECU 3 may vary the predetermined time T1 based on the temperature outside or inside the vehicle compartment detected by the temperature sensor. For example, the ECU 3 may increase the predetermined time T1 when the temperature detected by the temperature sensor increases. As the temperature in the passenger compartment increases, the pressure in the passenger compartment when the passenger compartment protection device 1 is activated tends to increase. Accordingly, the predetermined time T1 may be set longer as the temperature in the vehicle interior increases, and the vehicle exterior protection device 2 may be activated after the pressure in the vehicle interior during operation of the vehicle interior protection device 1 has sufficiently decreased. . Thereby, since the optimal predetermined time T1 is set according to the temperature environment, the glass breakage at the time of disposal of the protective devices 1 and 2 such as the airbag devices 1a to 1e and 2a and the pretensioner device 1f is further reduced. It can be surely prevented.

  In the first embodiment, the ECU 3 may vary the predetermined time T1 based on the open / closed state of the window or door of the vehicle.

  For example, if the ECU 3 determines that the vehicle window or door is in the open state, the ECU 3 may lengthen the predetermined time T1 to greatly shift the sound pressure peak of the noise generated from each of the devices 1a to 1f and 2a. . In addition, when the predetermined time T1 becomes long, noises generated from the devices 1a to 1f and 2a (including reflected sound) are not synthesized, so that noise can be more reliably suppressed. The open / closed state of the vehicle window or door is detected by an open / close sensor disposed on the vehicle window or door.

  Thus, when each of the airbag devices 1a to 1e or the pretensioner device 1f in the vehicle interior is actuated, an appropriate predetermined time T1 is taken into consideration that noise leaks from the open window or door and increases. Is set. Therefore, the noise at the time of disposal of the protection devices 1 and 2 such as the airbag devices 1a to 1e and 2a and the pretensioner device 1f can be effectively reduced. When the forced operation function is executed, the ECU 3 may stop the execution of the vehicle window or the door, or may give an alarm to the worker.

  In the first embodiment, the ECU 3 may vary the predetermined time T1 according to the current position at which the vehicle is discarded. Note that the current position of the vehicle may be detected by, for example, a navigation device.

  For example, when the current position of the vehicle is an urban area, the predetermined time T1 may be set to be long, and the sound pressure peaks of noise generated from the devices 1a to 1f and 2a may be greatly shifted. As a result, an appropriate predetermined time T1 is set according to the position at which the vehicle is disposed of, so that the protection devices 1 and 2 such as the airbag devices 1a to 1e and 2a and the pretensioner device 1f are disposed of. Noise can be effectively reduced.

  In the first embodiment, the ECU 3 may vary the predetermined time T1 according to the current time when the forced operation function is executed. For example, when it is a night time zone, the predetermined time T1 may be set longer and the sound pressure peaks of noise generated from the devices 1a to 1f and 2a may be greatly shifted. As a result, an appropriate predetermined time T1 is set according to the time at which the vehicle is disposed of. Therefore, when the protective devices 1 and 2 such as the airbag devices 1a to 1e and 2a and the pretensioner device 1f are disposed of. Noise can be effectively reduced.

(Second Embodiment)
FIG. 4 is a block diagram showing an example of a system configuration of the vehicle operation control apparatus according to the second embodiment.

  In the vehicle operation control apparatus 20 according to the present embodiment, the ECU 3 is connected to a pressure sensor 8 that is disposed in the passenger compartment and detects the pressure in the passenger compartment. The pressure in the passenger compartment detected by the pressure sensor 8 is transmitted to the ECU 3.

  The ECU 3 walks outside the vehicle compartment when the pressure in the vehicle compartment detected by the pressure sensor 8 when the airbag devices 1a to 1e or the pretensioner device 1f in the vehicle compartment are operated is equal to or lower than the predetermined pressure P1. The person protecting airbag device 2a may be operated.

  In the vehicle operation control apparatus 20 according to the second embodiment shown in FIG. 4, the same reference numerals are given to the same parts as those in the vehicle operation control apparatus 10 according to the first embodiment shown in FIG. Detailed description will be omitted.

  Next, the control processing flow of the vehicle operation control apparatus 20 according to the second embodiment will be described. FIG. 5 is a flowchart showing an example of a control processing flow of the vehicle operation control apparatus 20 according to the second embodiment.

  When the dedicated tool 6a is connected to the connector 6 and the ECU 3 receives the operation signal from the transmitter 7, the ECU 3 starts executing the forced operation function of each of the airbag devices 1a to 1e, 2a and the pretensioner device 1f (S200). .

  The ECU 3 transmits a drive signal to the squib drive circuit 4, and ignites and activates the squibs 21a to 21f of the airbag devices 1a to 1e or the pretensioner device 1f in the vehicle interior (S210).

  Next, the ECU 3 determines whether or not the pressure in the vehicle interior detected by the pressure sensor 8 when the airbag devices 1a to 1e or the pretensioner device 1f in the vehicle interior are operated is equal to or lower than a predetermined pressure P1. Judgment is made (S220).

  When the ECU 3 determines that the pressure in the vehicle interior detected by the pressure sensor 8 is equal to or lower than the predetermined pressure P1 (Yes in S220), the ECU 3 transmits a drive signal to the squib drive circuit 4 and a pedestrian airbag outside the vehicle interior. The squib 22a of the device 2a is ignited and activated (S230). On the other hand, when the ECU 3 determines that the pressure in the passenger compartment detected by the pressure sensor 8 is not equal to or lower than the predetermined pressure P1 (No in S220), the ECU 3 returns to the above-described (S220).

  As described above, in the vehicle operation control device 20 according to the second embodiment, the ECU 3 is detected by the pressure sensor 8 when the airbag devices 1a to 1e or the pretensioner device 1f in the vehicle interior are operated. When the pressure in the passenger compartment is equal to or lower than the predetermined pressure P1, the airbag device 2a for protecting pedestrians outside the passenger compartment is operated. Thereby, the noise generated when the airbag device 2a for protecting pedestrians outside the passenger compartment is activated and the noise generated when the airbag devices 1a to 1e and the pretensioner device 1f in the passenger compartment are activated. It can be generated and shifted in time.

  Note that the pressure in the passenger compartment varies according to the temperature in the passenger compartment (for example, when the temperature in the passenger compartment increases, the pressure in the passenger compartment increases). Therefore, when the pressure in the passenger compartment that fluctuates in accordance with the temperature change in the passenger compartment is equal to or lower than the predetermined pressure P1, the pedestrian protection airbag device 2a is operated to accurately The devices 1a to 1f and 2a can be operated.

  Further, the pressure in the passenger compartment during operation of each of the devices 1a to 1f and 2a varies depending on the state of deterioration of each of the devices 1a to 1f and 2a (a small amount of gas leakage, deterioration of the gas generating agent, etc.). Therefore, as described above, when the pressure in the passenger compartment that fluctuates according to the state of deterioration of each of the devices 1a to 1f and 2a is equal to or lower than the predetermined pressure P1, the pedestrian protection airbag device 2a is activated to It becomes possible to operate each apparatus 1a-1f, 2a with the exact timing according to the aged state of 1a-1f, 2a. In other words, the devices 1a to 1f and 2a can be operated at a more appropriate timing in accordance with the temperature in the passenger compartment and the fluctuation factors occurring in the aging state of the devices 1a to 1f and 2a. Thereby, the noise at the time of disposal of the protection devices 1 and 2 such as the airbag devices 1a to 1e and 2a and the pretensioner device 1f mounted on the vehicle can be more effectively reduced.

  Next, a modified example of the vehicle operation control apparatus 20 according to the second embodiment will be described.

  In the second embodiment, the ECU 3 includes the pretensioner device 1f in the vehicle interior, the side airbag device 1d, the passenger seat airbag device 1a, the curtain shield airbag device 1e, and the driver seat airbag device. 1a may be operated by shifting the peak of the sound pressure level of the noise generated by each of the devices 1f, 1d, 1a, and 1e in this order (FIGS. 6A and 6B). .

Further, ECU 3 is one of the inflator 12a in the passenger compartment of the pedestrian protection airbag device 2a, than the operation of the pretensioner device 1f, is operated as soon as the time difference T _10, other pedestrian protection airbag device 2a the inflator 12a, than the operation of the curtain shield airbag device 1e, actuating delayed by the time difference _{T 14} (FIG. 6 (c) and (d)).

Incidentally, as shown in FIG. 6 (b) and (d), the airbag device 1a, 1d, 1e and pretension Na device 1f, respectively, the predetermined time _{T 10, T 11, T 12} , T 13, T 14 It is operated with a time difference of. With this configuration, when each of the devices 2a, 1f, 1d, 1a, and 1e is operated in series, the peak of the sound pressure level of the noise generated from each device 2a, 1f, 1d, 1a, and 1e. Are surely shifted, and the synthesized sound pressure level is suppressed to a predetermined level or less.

The predetermined times T ₁₀ , T ₁₁ , T ₁₂ , T ₁₃ , and T ₁₄ are obtained in advance by experiments and set in the ROM 3 b of the ECU 3.

  In the second embodiment, the ECU 3 determines that the sound pressure level in the vehicle interior detected by the sound pressure sensor when the airbag devices 1a to 1e or the pretensioner device 1f in the vehicle interior are activated is a predetermined level. When the following is true, the pedestrian protection airbag device 2a outside the passenger compartment may be activated.

  Note that the sound pressure in the passenger compartment varies according to the temperature in the passenger compartment. Therefore, when the sound pressure in the passenger compartment that fluctuates in accordance with the temperature change in the passenger compartment is equal to or lower than a predetermined level, the airbag device 2a for protecting pedestrians is activated, and each of the sound pressures is accurately determined according to the temperature change. The devices 1a to 1f and 2a can be operated.

  Further, the sound pressure in the passenger compartment during operation of each of the devices 1a to 1f and 2a varies depending on the state of deterioration of each of the devices 1a to 1f and 2a (a small amount of gas leakage, deterioration of the gas generating agent, etc.). Accordingly, as described above, when the sound pressure in the passenger compartment, which fluctuates according to the state of deterioration of each of the devices 1a to 1f, 2a, is equal to or lower than a predetermined level, the pedestrian protection airbag device 2a is operated to It becomes possible to operate each apparatus 1a-1f, 2a with the exact timing according to the aged state of 1a-1f, 2a. In other words, the devices 1a to 1f and 2a can be operated at a more appropriate timing in accordance with the temperature in the passenger compartment and the fluctuation factors occurring in the aging state of the devices 1a to 1f and 2a. Thereby, the noise at the time of disposal of the protection devices 1 and 2 such as the airbag devices 1a to 1e and 2a and the pretensioner device 1f mounted on the vehicle can be more effectively reduced.

  In the second embodiment, when the load applied when the airbags of the airbag devices 1a to 1e in the vehicle interior are detected by the load sensor is equal to or less than a predetermined load, the ECU 3 The pedestrian protection airbag device 2a may be activated.
