BACKGROUND OF THE INVENTION
The present invention relates to an actuator fixing jig for an automatic vehicle driving apparatus and an actuator mounting method for an automatic vehicle driving apparatus.
[0002]
[Prior art]
[Patent Document 1] JP-T-4-503712 [Patent Document 2] JP-A-5-31287 [Patent Document 3] JP-A-63-246632 [Patent Document 4] Japanese Utility Model Publication No. 6-43722 As conventional vehicle automatic driving devices used for vehicle tests such as performance tests and exhaust gas tests performed by setting a vehicle on a chassis dynamo and running the vehicle according to a predetermined procedure, Patent Documents 1, 2, and 3 described above. As shown, an actuator for operating each pedal (accelerator pedal, brake pedal) of the vehicle, operating a shift lever, and an engine key, and a main body for sending electric power and control signals to the actuator, There is a so-called integrated vehicle automatic driving device fixed to the side.
[0003]
The vehicle automatic driving device has been developed and put into practical use for the purpose of driving a vehicle by a robot instead of a human when performing the vehicle test.
[0004]
[Problems to be solved by the invention]
However, in the integrated vehicle automatic driving device, when the tester drives after driving the vehicle and carries the vehicle outside from the chassis dynamo, the main body fixed to the driver's seat side or the main body is fixed. There is a problem that it is necessary to remove the member (cylinder, etc.), and it takes time to remove.
[0005]
Further, as shown in Patent Document 4, the main body is not fixed to the driver's seat side, but is fixed to the passenger seat side, or is not disposed in the vehicle, and an actuator for operating the shift lever is provided as an assistant. There is a so-called separation type automatic vehicle driving device that is fixed to the seat side and only three accelerator pedals, brake pedals, and engine key operating actuators are fixed to the driver's seat side.
[0006]
In the above-described separated type automatic vehicle driving device, it is necessary to remove the main body fixed to the driver's seat side when the tester drives and carries the vehicle out of the chassis dynamo after the vehicle test. There is an advantage that the next vehicle test can be started smoothly.
[0007]
In such a separate type automatic vehicle driving apparatus, a fixing jig is used to fix the accelerator pedal, the brake pedal, and the three actuators for operating the engine key to the driver's seat side. As a jig, there is a mounting jig that is attached to the floor in front of the driver's seat (refer to the prior art in Patent Document 4 above).
[0008]
However, in the separation type automatic vehicle driving apparatus, there is a problem that a plurality of mounting jigs having different shapes need to be prepared because the floor space in front of the driver's seat differs depending on the vehicle type or the like. In addition, after the vehicle test is completed, when the tester drives the test vehicle and carries it out of the chassis dynamo, it takes time to remove the actuator that is fixed in front of the driver's seat and interferes with the driving. There was also a problem.
[0009]
Further, as another fixing jig, there is one that is mounted on a seat portion of a driver's seat as shown in Patent Document 4 above.
[0010]
However, even in the separated type automatic vehicle driving apparatus having the above configuration, when the tester drives after driving the vehicle and carries the vehicle out of the chassis dynamo, the fixing jig on the seat portion of the driver's seat and It was necessary to remove the three actuators fixed to the fixing jig, and there was a problem that it took time to remove. In addition, since the seat portion to which the fixing jig is attached has a cushioning property, when the accelerator pedal actuator and the brake pedal actuator step on each pedal, the actuators move backward with the fixing jig to some extent. As a result, the stepping of each pedal has become shallow due to this retreat, and as a result, the driving for the vehicle test may end in an incomplete manner.
[0011]
The present invention has been made in consideration of the above-mentioned matters, and the object thereof is to reduce the time required for the vehicle test performed using the vehicle automatic driving device and to perform the vehicle test more accurately. It is an object to provide an actuator fixing jig for an automatic vehicle driving device and an actuator mounting method for the automatic vehicle driving device.

Item 1).
[0013]
With the above configuration, it is possible to reduce the time required for the vehicle test performed using the automatic vehicle driving device. That is, after performing a vehicle test using the vehicle automatic driving device, when the tester drives the vehicle subjected to the test and carries it out from the chassis dynamo to the outside, the fixing jig fixed in front of the driver seat By moving the clamp part to the left and right together with the actuator, the tester can sit in the driver's seat and drive without any problems, and use the same chassis dynamo to prepare smoothly for the next vehicle test. As a result, it is possible to shorten the time required for the vehicle test performed using the automatic vehicle driving device.
[0014]
The hole may be a long hole (claim 2).
[0015]
In this case, even if the distance and position between the fixing bolts are various, the fixing jig can be attached regardless of the type if the seat rail is a vehicle fixed with the fixing bolt. The fixing jig is very versatile.
[0016]
Further, the main body fixed to the front side of the driver's seat may be configured so as not to prevent an operation of a lever for releasing the fixing of the driver's seat with respect to the seat rail.
[0017]
In this case, even if the fixing jig is attached to the front side of the driver's seat, the driver's seat can be easily moved back and forth.
[0018]
In order to achieve the above object, an actuator mounting method for an automatic vehicle driving device according to the present invention fixes the actuator fixing jig of the automatic vehicle driving device according to any one of claims 1 to 3 to the front side of the driver's seat. After that, the driver's seat is moved to the front side and is brought into pressure contact with the actuator fixing jig of the automatic vehicle driving device (claim 4).
[0019]
With the above-described configuration, it is possible to reduce the time required for a vehicle test performed using the vehicle automatic driving device, and to provide an actuator mounting method for the vehicle automatic driving device that enables the vehicle test to be performed more accurately. It becomes possible to do.
[0020]
Further, in the method of attaching an actuator of the vehicle automatic driving device, when the driver's seat is pressed against a fixing jig attached to the front side of the driver's seat and the vehicle test is performed in this state, the accelerator pedal actuator and the brake pedal actuator are respectively When each pedal is stepped on, each actuator is retracted somewhat together with the fixing jig due to the reaction, and it is reliably prevented that the depression of each pedal is shallow due to this backward movement. It is no longer incomplete and the vehicle test can always be performed more accurately.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1A and 1B are a perspective view schematically showing a configuration of an actuator fixing jig (hereinafter referred to as a fixing jig) D of an automatic vehicle driving apparatus according to an embodiment of the present invention, FIG. FIG. 3 is a front view and a side view schematically showing the configuration of the fixing jig D. FIG.
The fixing jig D is a vehicle test such as a performance test, an exhaust gas test or an endurance test performed by setting a vehicle on a chassis dynamo and running the vehicle according to a predetermined procedure by an automatic vehicle driving device (not shown). The three automatic actuators 1, 2, and 3 (see FIG. 2 and FIG. 3), which will be described later, of the automatic vehicle driving apparatus are attached to the front side of the driver seat 4 in the vehicle.
[0022]
The automatic vehicle driving apparatus includes an accelerator pedal actuator 1 that performs a depression operation of an accelerator pedal (not shown) of a vehicle, a brake pedal actuator 2 that performs a depression operation of a brake pedal (not shown), and an engine key ( An engine key actuator 3 for rotating an ignition key (not shown), and a shift lever actuator (not shown) for operating a shift lever (not shown) are provided. The shift lever actuator of the automatic vehicle driving device is fixed to the passenger seat (not shown) side.
[0023]
The fixing jig D includes three clamp portions 5, 5... That hold the accelerator pedal, the brake pedal, and the engine key operation actuators 1, 2, 3 detachably and adjustable in angle, and three clamp portions 5. , 5... And a main body 7 having a slide rail 6 at the upper end for holding the position adjustable in the left-right direction.
[0024]
The slide rail 6 has a groove portion 6a extending in the left-right direction of the vehicle, and the clamp portion 5 is inserted through a substantially U-shaped holding body 5a and an open end of the holding body 5a. A lower end portion is provided with a rotating member 5 b that is locked in the groove portion 6 a of the slide rail 6.
[0025]
Specifically, the holding body 5a has a holding hole 9 provided at a rear end portion of each actuator 1, 2, 3 and into which a protruding portion 8 protruding in the left-right direction of the vehicle is inserted.
[0026]
The rotating member 5b rotates about the axis by rotating the handle portion 5c provided at the upper end thereof, and the size of the holding hole 9 changes with this rotation. At the same time, the clamp part 5 changes to a slidable state and a non-slidable fixed state with respect to the groove 6a of the slide rail 6.
[0027]
The main body 7 has a substantially frame shape, and has a bottom surface portion 7a and two standing surface portions 7b and 7b that rise upward from rear end portions of left and right portions of the bottom surface portion. . The left and right portions of the bottom surface portion 7a and the standing surface portions 7b are respectively provided with long holes 10 that are long in the left-right direction of the vehicle. In addition, the said long hole 10 is for inserting the fixing bolt 13 mentioned later.
[0028]
The driver's seat 4 is held by two seat rails 11, 11, and a lever 12 for releasing the fixation of the driver's seat 4 with respect to the seat rails 11, 11 is provided at the lower part thereof. When the lever 12 is pulled, the driver seat 4 is movable in the front-rear direction.
[0029]
Next, a method for attaching the three actuators 1, 2, 3 using the fixing jig D will be described.
First, the fixing bolts 13 of the seat rails 11 and 11 are removed. And the fixing jig D is arrange | positioned so that the position of the said long holes 10 and 10 may fit in the bolt holes 11a and 11a to which the fixing bolts 13 and 13 were attached. At this time, as shown in FIG. 1A, when the bolt hole 11a is substantially forward, the long hole 10 provided in the rising surface portion 7b is aligned with the position of the bolt hole 11a. In addition, as shown in FIG. 1B, when the bolt hole 11a is substantially upward, the long hole 10 provided in the bottom surface portion 7a is aligned with the position of the bolt hole 11a.
[0030]
Subsequently, the fixing bolt 13 is attached to the original bolt hole 11a even in a state where the fixing bolt 13 is inserted into the elongated hole 10. As a result, the fixing jig D is fixed in front of the driver's seat 4. Here, the fixing bolt 13 is not limited to the fixing bolt 13 attached to the seat rail 11 from the beginning, but can be attached to the bolt hole 11a, and is used as a bolt for fixing the seat rail 11 at a predetermined position. Anything can be used.
[0031]
Thereafter, the lever 12 is pulled, the driver's seat 4 is moved to the front side, and is brought into pressure contact with the fixing jig D. The operation of pulling the lever 12 can be easily performed without being obstructed by the fixing jig D because the main body 7 of the fixing jig D has a frame shape.
[0032]
The actuator 1 is attached to the fixing jig D installed as described above as follows. That is, first, the protruding portion 8 of the actuator 1 is inserted into the holding hole 9 of each clamp portion 5, and in this state, is moved to a suitable position in the left-right direction of the vehicle (according to the position of the accelerator pedal). After that, it is only necessary to adjust the angle around the axis extending in the left-right direction of the vehicle and finally rotate the handle portion 5c. As a result, the holding hole 9 is reduced, the protruding portion 8 of the actuator 1 cannot be removed from the holding hole 9, the actuator 1 is held at the previously adjusted angle, and the clamp portion 5 is connected to the slide rail 6. Since the actuator cannot slide along the groove 6a, the actuator 1 does not move in the left-right direction and is fixed.
[0033]
Since the actuators 2 and 3 can be attached to the clamp portion 5 in the same manner as the actuator 1, the description thereof is omitted.
[0034]
With the fixing jig D having the above-described configuration, it is possible to shorten the time required for the vehicle test performed using the automatic vehicle driving device and to perform the vehicle test more accurately.
[0035]
That is, after the vehicle test is performed using the automatic vehicle driving apparatus, when the tester drives the vehicle subjected to the test and carries it out from the chassis dynamo to the outside, the fixing jig fixed in front of the driver seat 4 By moving the clamp portions 5, 5... Of D together with the actuators 1, 2, and 3 to the left and right, the tester can sit in the driver's seat 4 and drive without any trouble, using the same chassis dynamo. The preparation for performing the vehicle test can be performed smoothly, and as a result, the time required for the vehicle test performed using the automatic vehicle driving apparatus can be shortened.
[0036]
Further, in the fixing jig D, since the holes through which the fixing bolts 13 and 13 are inserted are the long holes 10 and 10, there are various distances and positions between the fixing bolts 13 and 13 of the seat rails 11 and 11. However, if the vehicle is a vehicle in which the seat rails 11 and 11 are fixed by fixing bolts 13 and 13, the fixing jig D can be attached regardless of the type of the vehicle. The fixing jig D is very versatile. It has become an excellent one.
[0037]
Further, in the fixing jig D, the main body 7 fixed to the front side of the driver's seat 4 does not disturb the operation of the lever 12 for releasing the fixing of the driver's seat 4 to the seat rails 11 and 11. Therefore, even when the fixing jig D is attached to the front side of the driver's seat 4, the driver's seat 4 can be easily moved back and forth.
[0038]
Then, when the driver's seat 4 is brought into pressure contact with the fixing jig D attached to the front side of the driver's seat 4 and the vehicle test is performed in this state, the accelerator pedal actuator 1 and the brake pedal actuator 2 each step on each pedal. In addition, the reaction prevents the actuators from moving back together with the fixing jig, and the retraction of the pedals to prevent the pedals from being shallowly depressed. As a result, the vehicle test operation is completed in an incomplete manner. The vehicle test can always be performed more accurately.
[0039]
In addition, when the bolt hole 11a to which the fixing bolt 13 is attached is neither forward nor upward but is provided obliquely upward, for example, a spacer having an appropriate shape is attached to the fixing bolt 13 for attachment. You may do it.
[0040]

It is possible to provide an actuator fixing jig for an automatic vehicle driving apparatus and an actuator mounting method for an automatic vehicle driving apparatus.
[0041]
That is, after performing a vehicle test using the vehicle automatic driving device, when the tester drives the vehicle subjected to the test and carries it out from the chassis dynamo to the outside, the fixing jig fixed in front of the driver seat By moving the clamp part to the left and right together with the actuator, the tester can sit in the driver's seat and drive without any problems, and use the same chassis dynamo to prepare smoothly for the next vehicle test. As a result, it is possible to shorten the time required for the vehicle test performed using the automatic vehicle driving device.
[0042]
In addition, if the driver's seat is pressed against a fixing jig attached to the front side of the driver's seat and the vehicle test is performed in this state, when the accelerator pedal actuator and the brake pedal actuator step on each pedal, the reaction will occur. Each actuator is retracted somewhat together with the fixing jig, and it is reliably prevented that the depression of each pedal is made shallow by this retraction, and as a result, the operation for the vehicle test may be completed in an incomplete manner. The vehicle test can always be performed more accurately.
