Japanese Patent Laid-Open No. 7-25300

  This invention is made in view of this point, and makes it a subject to provide the vehicle construction technique effective in coping with the collision of the collision object outside a vehicle from the vehicle side.

  The present invention is configured to solve the above problems. In addition, this invention is a technique applicable to the structure of the vehicle collision apparatus mounted in various vehicles, such as a motor vehicle, a bus, a train, a truck, and a ship.

(First invention of the present invention)
A first aspect of the present invention is a vehicle collision device as set forth in claim 1.
The vehicle collision device according to claim 1 is a device mounted on the vehicle, and includes at least a detection unit, an impact receiving unit, a drive unit, and a control unit.

  The detection unit of the present invention has a function of detecting information related to a vehicle collision. Information detected by the detection unit includes information for predicting (determining) whether the host vehicle collides with an external collision object such as another vehicle or an obstacle, typically between the collision object and the external collision object. Distance, relative speed, etc. are used. As a specific example of this detection unit, a radio wave (millimeter wave or laser light) having a wavelength of several millimeters is generated toward the collision object outside the vehicle, and the reflected wave from the collision object outside the vehicle is measured to thereby detect the collision with the collision object outside the vehicle. An imaging means such as a so-called “millimeter wave radar” or “laser radar”, a 3D compound eye camera or a monocular camera, or a 2D camera, which can detect (measure) the distance between them, the relative speed, etc. is used. be able to.

  The impact receiving portion of the present invention has a function of receiving an impact from a vehicle collision object on the side of the vehicle in the event of a vehicle accident. As used herein, “outside vehicle collision object” includes various types of collision objects that exist outside the host vehicle and can collide with the host vehicle. Specifically, other vehicles and pedestrians traveling outside the host vehicle are included. Occupants on bicycles, obstacles such as pillars and guardrails. Since the impact from the collision object outside the vehicle is received by the impact receiving portion, it is possible to improve the shock absorption performance at the time of the collision and to improve the protection of the vehicle occupant of the own vehicle. Vehicle components such as a vehicle door, a side door trim, a side roof rail, and a pillar can be used as a place where the impact receiving portion is mounted. In the present invention, the impact-receiving portion is made of a material having an impact absorbing function such as a foam material or an air bag body, thereby improving the protection of a traffic weak person such as a pedestrian, a bicycle or a motorcycle. Can also be achieved.

  The drive unit of the present invention has a function capable of reversibly driving the receiving unit between the receiving standby position and the receiving position. This receiving position is a position between the vehicle side wall and the vehicle collision object and outside the vehicle from the receiving standby position. It should be noted that the receiving standby position may be formed between the vehicle side wall and the collision object outside the vehicle, or may be formed on the vehicle inner side than the vehicle side wall. Due to the reversible driving mode of the impact receiving portion, the impact receiving portion is once driven from the impact standby position to the impact receiving position, and can be returned to the impact standby position as necessary.

  The control unit of the present invention has a function of controlling the drive unit based on information detected by the detection unit, and includes at least a first control mode and a second control mode. The first control mode is a control mode in which, when a vehicle collision is predicted based on detection information of the detection unit, the drive unit is controlled before the vehicle collision to move the receiving unit from the receiving standby position to the receiving position. It is said. In the second control mode, when it is determined that a vehicle collision has been avoided after setting the first control mode based on the detection information of the detection unit, the drive unit is controlled to move the receiving unit from the receiving position to the receiving standby position. It is set as the control mode to move to. In the present invention, the receiving standby position and the receiving position are not defined only as a predetermined fixed point, but are also defined as an area having a certain width with respect to the moving direction of the receiving unit. Further, the control unit may be configured to control only the impact receiving unit, or in addition to the impact receiving unit, control of vehicle components other than the impact receiving unit, for example, engine running system and electrical system It may be configured to perform the control together.

According to such a configuration of the vehicle collision device according to claim 1, when the collision of an external collision object toward the vehicle side wall is predicted, the receiving unit is operated in advance from the receiving standby position to the receiving position. In other words, it becomes possible to prepare for a collision accident that may occur thereafter. As a result, it is possible to perform shock absorption at the time of an accident when using an impact receiving portion that has been moved in the direction approaching the vehicle collision object in advance, so that the impact receiving portion operates immediately after the occurrence of the accident. Compared to the above, the impact absorbing performance can be improved, and the protection of the vehicle occupant of the host vehicle can be improved. In addition, since the receiving part can be brought closer to the collision object outside the vehicle in preparation for the occurrence of the collision, the time required to start the receiving can be shortened. Further, the collision energy received by the vehicle main body can be mitigated by the receiving portion, and damage to the vehicle door main body can be suppressed. Further, when the vehicle collides, since the receiving part comes into contact with the collision object outside the vehicle at the receiving position before the vehicle main body, the actual occurrence of the vehicle collision can be detected earlier. Accordingly, the occupant restraining performance can be improved because the occupant restraint device such as an air bag or a seat belt mounted in the vehicle can be operated with sufficient margin to restrain the occupant with certainty. On the other hand, when a collision does not actually occur after the vehicle collision is predicted, the receiving unit can be returned from the receiving position to the receiving standby position to prepare for the next collision prediction.
In the first control mode and the second control mode, the movement of the receiving unit between the receiving position and the receiving standby position is 1 between the receiving position and the receiving standby position. It may move in steps (one stage), or may move in multiple steps (multistage).

The detection unit, the receiving unit, the driving unit, and the control unit in the present invention are configured substantially the same as the detection unit, the receiving unit, the driving unit, and the control unit in the vehicle collision device according to claim 1. .

Therefore, according to such a configuration of the vehicle according to claim 4, when the collision of the collision object outside the vehicle heading to the vehicle side wall is predicted, the impact receiving unit is previously operated from the impact standby position to the impact position. In other words, it becomes possible to prepare for a collision accident that may occur thereafter. As a result, it is possible to perform shock absorption at the time of an accident when using an impact receiving portion that has been moved in the direction approaching the vehicle collision object in advance, so that the impact receiving portion operates immediately after the occurrence of the accident. Compared to the above, the impact absorbing performance can be improved, and the protection of the vehicle occupant of the host vehicle can be improved. In addition, since the receiving part can be brought closer to the collision object outside the vehicle in preparation for the occurrence of the collision, the time required to start the receiving can be shortened. Further, the collision energy received by the vehicle main body can be mitigated by the receiving portion, and damage to the vehicle door main body can be suppressed. On the other hand, when a collision does not actually occur after the vehicle collision is predicted, the receiving unit can be returned from the receiving position to the receiving standby position to prepare for the next collision prediction.
In the first control mode and the second control mode, the movement of the receiving unit between the receiving position and the receiving standby position is 1 between the receiving position and the receiving standby position. It may move in steps (one stage), or may move in multiple steps (multistage).

When it is determined that the vehicle 10 has actually caused an accident, an occupant restraint device (not shown) such as an airbag or a seat belt mounted in the vehicle 10 is appropriately operated to restrain the occupant.

  Here, a specific configuration of the impact receiving device 110 will be described with reference to FIGS. 2 and 3. 2 shows a cross-sectional structure taken along line AA of the vehicle door 11 in FIG. 1, and FIG. 3 shows a cross-sectional structure taken along line BB of the vehicle door 11 in FIG.

  As illustrated in FIGS. 2 and 3, the impact receiving device 110 has a function of receiving an impact from a vehicle-side collision object on the side of the vehicle, and includes at least an impact receiving member 111 and a drive mechanism 120. The impact receiving device 110 constitutes an “impact receiving portion” and an “impact receiving member” in the present invention. In the example shown in FIGS. 2 and 3, the impact receiving device 110 is mounted on the vehicle door 11 corresponding to the passenger seat, but the reception device 110 is similarly applied to the vehicle door corresponding to the driver seat and the rear seat. The impact device 110 can be attached.

  The impact receiving member 111 has a first component 111a and a second component 111b. The first component 111a is exposed on the door surface (also referred to as “vehicle side wall”) of the vehicle door 11 among the parts of the impact receiving member 111, and extends in the longitudinal direction along the door surface in the vehicle front-rear direction. It is configured as an existing part. This 1st structure part 111a is comprised as a member which receives the substantial impact from the vehicle exterior collision object of the vehicle side. The second component 111b is configured as a portion that extends in the longitudinal direction in the vehicle front-rear direction in the space 17 between the outer panel 13 and the inner panel 15 among the portions of the impact receiving member 111. This second component 111 b has the original function of the door beam for reinforcing the vehicle door 11. In the present embodiment, the second component 111b is slidable in the vehicle left-right direction through an opening 13a formed in the outer panel 13.

  The drive mechanism 120 has a function of driving the impact receiving member 111 based on a control signal from the control unit 140, and is configured mainly with a link arm 122, a rotation motor 124, and a ball screw member 125. The drive mechanism 120 constitutes a “drive unit” in the present invention. The drive mechanism 120 is also referred to as an “actuator” for the impact receiving device 110 (the impact receiving member 111).

  The link arm 122 is an arm member extending between a pair of front and rear mounting pieces 121 and 121 on the side of the impact receiving member 111 and a pair of front and rear mounting pieces 123 and 123 on the inner panel 15 side. Is configured. Specifically, one end of each link arm 122 is attached to each attachment piece 121 slidable in the vehicle front-rear direction with respect to the impact receiving member 111 via a rotation shaft 122a. The other end of each is attached to each attachment piece 123 fixed to the inner panel 15 via a rotation shaft 122b.

  The rotation motor 124 is configured as a motor that enables the ball screw member 125 to rotate around its axis. The rotation motor 124 controls the rotation direction and the rotation speed of the rotation motor 124 and the ball screw member 125 based on a control signal from the control unit 140.

  The ball screw member 125 is an axial ball screw member that extends in the longitudinal direction in the vehicle longitudinal direction, and is configured as a member having a screw thread that is screwed in correspondence with a screw groove formed in the mounting piece 121. . This ball screw member 125 is also referred to as a “feed screw member”.

  Here, the operation of the vehicle collision apparatus 100 configured as described above will be described with reference to FIGS. 4 to 6 in addition to FIGS. FIG. 4 is a perspective view showing a state during operation of the impact receiving device 110 in FIG. 5 shows a cross-sectional structure taken along line CC of the vehicle door 11 in FIG. 4, and FIG. 6 shows a cross-sectional structure taken along line DD of the vehicle door 11 in FIG.

The state shown in FIGS. 1 to 3 of the vehicle collision device 100 is a state before the collision is predicted by the detection sensor 130 and the impact receiving device 110 is set to the impact standby position before the impact. On the other hand, the state shown in FIGS. 4 to 6 of the vehicle collision device 100 is a state immediately after the collision is predicted by the detection sensor 130 and the impact receiving device 110 is set to the impact position.
The control unit 140 is set to the following first control mode when controlling the impact receiving device 110 from the impact standby position to the impact position based on the collision prediction by the detection sensor 130. On the other hand, after the first control mode, when the impact receiving device 110 is controlled again from the impact receiving position to the impact waiting position based on the collision prediction by the detection sensor 130, the following second control mode is set. Is done.

(First control mode)
In the first control mode, the rotation motor 124 is driven by a control signal from the control unit 140, and the pair of front and rear mounting pieces 121, 121 move in a direction away from each other in the vehicle front-rear direction. The direction of rotation is controlled. As a result, the impact receiving member 111 moves outward from the vehicle, and the relative position between the impact receiving member 111 and the vehicle door 11 changes from the state shown in FIGS. 1 to 3 to the state shown in FIGS. 4 to 6. Switch to. Specifically, the first component 111a of the impact receiving member 111 is separated from the door surface of the vehicle door 11, and the second component 111b of the impact receiving member 111 passes the opening 13a of the outer panel 13 outward of the vehicle. Slide. The impact from the collision object outside the vehicle is received by the impact receiving member 111 that is driven and controlled in the first control mode. In the first control mode, when the control unit 140 predicts a collision of the vehicle 10 based on the detection information of the detection sensor 130, the drive mechanism 120 is controlled before the vehicle collision to wait for the receiving member 111. This is a control mode for moving from the position to the receiving position, and this first control mode corresponds to the “first control mode” in the present invention.

  Further, regarding the configuration of the impact receiving member 111 of the present embodiment, it is preferable that at least the surface portion of the first component 111a is configured by a material having an impact absorbing function such as a foam material, an airbag body, or the like. According to such a configuration, when the collision object outside the vehicle is a traffic weak person such as a pedestrian or a rider riding a bicycle or motorcycle, it is possible to provide a function of improving the protection of the pedestrian or the occupant.

(Second control mode)
In the second control mode, the rotary motor 124 is driven by a control signal from the control unit 140, and the pair of front and rear mounting pieces 121, 121 move in a direction close to each other in the vehicle front-rear direction. The direction of rotation is controlled. As a result, the impact receiving member 111 moves inward of the vehicle, and the relative position between the impact receiving member 111 and the vehicle door 11 changes from the state shown in FIGS. 4 to 6 to the state shown in FIGS. Return to. Specifically, the first component 111a of the impact receiving member 111 is attached close to the door surface of the vehicle door 11, and the second component 111b of the impact receiving member 111 opens the opening 13a of the outer panel 13. Slide inward into the vehicle. In the second control mode, when the control unit 140 determines that the collision of the vehicle 10 is avoided after setting the first control mode based on the detection information of the detection sensor 130, the control unit 140 controls the drive mechanism 120 to receive the collision. This is a control mode in which the member 111 is moved from the receiving position to the receiving standby position, and this second control mode corresponds to the “second control mode” in the present invention.

  When the impact receiving member 111 is driven and controlled to the second control mode, the collision is predicted once, but the collision is avoided by the subsequent action of the driver of the host vehicle 10 or the outside collision object side. In addition, the receiving member 111 can be quickly returned to the receiving standby position (initial setting). Thus, the impact receiving member 111 of the present embodiment has a drive mode that can reversibly move between the impact standby position and the impact receiving position. In the second control mode and the first control mode described above, the movement of the impact receiving member 111 between the impact receiving position and the impact waiting position is as follows. May be moved in one step (one step), or may be moved in a plurality of steps (multiple steps). Further, regarding the control mode in the control unit 140, in addition to the first control mode and the second control mode, another different control mode may be set.

As described above, according to the vehicle collision device 100 and the vehicle 10 equipped with the vehicle collision device 100 according to the present embodiment, when the collision of an external collision object toward the vehicle side wall is predicted, the impact receiving member 111 is It is possible to prepare for a collision accident that may occur afterward by operating in advance from the receiving standby position to the receiving position. As a result, the impact receiving member 111 that has been moved in the direction approaching the collision object outside the vehicle in advance can be used to absorb the impact at the time of the collision, so that the impact receiving portion such as the impact receiving member 111 can be used. As compared with the configuration that operates immediately after the accident occurs, the impact absorption performance can be improved, and the protection of the vehicle occupant of the host vehicle 10 can be improved. In addition, since the impact receiving member 111 can be brought closer to the collision object outside the vehicle in preparation for the occurrence of the collision, the time required to start the impact can be shortened. Further, the collision energy received by the vehicle body can be mitigated by the receiving portion, and damage to the vehicle door 11 body can be suppressed.
Further, according to the present embodiment, in the event of a vehicle collision, the impact receiving member 111 comes into contact with an external collision object at the impact position before the vehicle main body, so that the actual occurrence of the vehicle collision can be detected earlier. Can do. Accordingly, the occupant restraining performance can be improved because the occupant restraint device such as an air bag or a seat belt mounted in the vehicle can be operated with sufficient margin to restrain the occupant with certainty.
In addition, according to the present embodiment, by using the impact receiving member 111 that extends in the longitudinal direction in the vehicle front-rear direction, it is effective to perform the impact in a wide range corresponding to the collision object outside the vehicle.
In addition, according to the present embodiment, since the impact receiving member 111 including the first component 111a and the second component 111b is used, the rational use of the door beam of the vehicle door 11 as the impact receiving portion (impact member).
