Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simulation device that allows an evaluator to simulate a vehicle riding state for the purpose of evaluating vehicle characteristics.

[0002]

2. Description of the Related Art When designing a vehicle such as an automobile, evaluation of vehicle characteristics such as habitability, maneuverability, drivability, operability, visibility and safety from the viewpoint of a driver or a passenger. It is essential that the results be reflected in the design. The evaluation in that case is performed based on the sensibilities of the driver and the like (in this specification, “sensitivity” refers to the overall sensation obtained as a combined action of a plurality of sensations). In order to optimize the vehicle design, it is desirable to perform the above evaluation by a method that appeals to the sensitivity.

For this reason, conventionally, the following evaluation work has been performed in order to appeal the evaluation of vehicle characteristics to the sensibilities of the driver or the like. That is, for a vehicle prototype-produced under a predetermined design concept, first, the first kansei evaluation (in this specification, “kansei evaluation” means sensibility-based evaluation. Here, the evaluator is a driver or the like. The evaluation performed by the evaluator on the vehicle characteristics based on the overall feeling received from the vehicle characteristics from the standpoint of (1).), The design change is made based on the result, and further based on the design change contents. Prototype again,
A second sensitivity evaluation was performed on this re-prototype vehicle, and the work of repeating design change, re-trial manufacture, and sensitivity evaluation was performed in the same procedure as above until an evaluation of a predetermined reference level or higher was obtained.

[0004]

However, in such a conventional vehicle characteristic evaluation work, it is necessary to make a design change and make a prototype each time a new sensitivity evaluation is performed, so time, man-hours and cost are required. However, there is a problem in that the design efficiency is extremely low due to the cost. Moreover, the cycle of sensitivity evaluation-design change-trial manufacture-sensitivity evaluation-cannot be continuously performed in a short time, so that the sensitivity evaluation timings of the respective times are largely deviated from each other in terms of time. However, there is a problem in that it is difficult to optimize the vehicle design because it is not constant.

On the other hand, if the vehicle characteristic evaluation work can be performed at the design stage before the trial production without trial production, the above problem can be solved. As a vehicle characteristic evaluation work at this design stage, evaluation of body strength, rigidity, etc. using a numerical simulation has been conventionally performed. However, even with the same vehicle characteristic evaluation, it is impossible to directly apply the evaluation method for the characteristic unrelated to the driver's sensitivity to the sensitivity evaluation.

Further, conventionally, for example, Japanese Patent Laid-Open No. 2-259964.
As disclosed in Japanese Patent Publication, there is one that enables a vehicle characteristic evaluation at the design stage by a kind of simulation device using CAD. In this case, the evaluation is a visual sensory evaluation (single). This is only an evaluation based on one sense), not a kansei evaluation.

[0007] Further, Japanese Patent Laid-Open No. 5-108002 discloses a "kansei evaluation device", which is evaluated by adding sensory evaluation of an object (image) by an evaluator to the sensory evaluation and analysis based on the gaze time. It is merely an attempt to improve the reproducibility and the reliability of the evaluation result, and does not perform the sensitivity evaluation. It should be noted that although the publication describes "Kansei evaluation", the sensory evaluation is merely performed by setting an evaluation axis relating to visual information.

Further, in each of the above publications, there is no mention of taking in the evaluation result as design data and reflecting it in the vehicle design.

The present invention has been made in view of such circumstances, and the sensitivity evaluation of vehicle characteristics can be performed without using a prototype vehicle, and the evaluation result is accurately reflected in vehicle design. It is an object of the present invention to provide a simulation device that can be used.

[0010]

According to the present invention, a vehicle characteristic is simulated with a plurality of parameters, a predetermined stimulus is given to a plurality of senses of an evaluator according to the contents of these parameters, and the stimulus is given.

That is, as described in claim 1 and as shown in FIG. 1, the simulation apparatus according to the present invention is a simulation apparatus for allowing an evaluator to experience a simulated vehicle riding state for the purpose of evaluating vehicle characteristics. There
Vehicle characteristic simulating means (A) for simulating the vehicle characteristic with a plurality of parameters, sensory stimulus imparting means (B) for stimulating the plurality of sensations of the evaluator, and a sensation to which this stimulus is applied. And stimulus content setting means (C) for setting the stimulus application amount according to the content of the parameter, and parameter adjusting means (D) for adjusting the parameter according to the input operation of the evaluator who received the stimulus. , Data output means (E) for outputting the parameter after the adjustment,

It goes without saying that the "plurality of parameters" include, as a part thereof, parameters (for example, the parameters listed in claim 6) that directly affect the content of the stimulus application to the sense of the evaluator. In addition to this, vehicle design model data as described in claim 2 (specifically, vehicle interior space design model data as described in claim 3) or evaluator data as described in claim 4 (that As a specific example, the eyeball position data and line-of-sight direction data of the evaluator described in claim 5) may be included.

The above-mentioned "sensation" means the five senses (visual, auditory, olfactory, tactile, taste), as well as the physical sensation (acceleration, etc.), the sense of heat and humidity,
It is a broad concept that includes pressure and other sensations that are difficult to include in the above five senses.

The combination of the "plurality of sensations" is not particularly limited as long as it is two or more sensations, but in view of the fact that the influence on the sensitivity of the evaluator is considered to be the largest in the sense of sight. As described in claim 7, it is preferable to set the visual sense as one of the senses to which the stimulus is applied.

The "sensory stimulus applying means" is not particularly limited in its specific constitution as long as it can apply a stimulus to a plurality of senses of the evaluator.
For example, a device provided with a two-dimensional image presenting device or a three-dimensional stereoscopic image presenting device as described in claim 8, a device provided with a driving simulator as described in claim 9, or both of them. It is also possible to adopt the ones. As a specific example of the “three-dimensional stereoscopic image presenting means”, a head mounted display (HMD), a stereoscopic screen (a combination of a screen and liquid crystal shutter glasses or polarizing glasses), etc. can be adopted.

The above-mentioned "input operation" means an operation which reflects the intention of the evaluator, and for example, a manual input operation, an input operation by a voice instruction, etc. can be adopted.

The above "evaluation of vehicle characteristics" is not particularly limited as long as it is an evaluation of vehicle characteristics (that is, characteristics relating to the vehicle). For example, the evaluation as described in claims 10 to 12 It can be adopted, and in particular, when the driving simulator as described in claim 9 is provided as the “sensory stimulus imparting means”,
The evaluation of the contents as described in claims 13 to 20 can be adopted.

[0018]

As described above, in the present invention (the invention according to claim 1), the vehicle characteristics are simulated by a plurality of parameters, and a plurality of evaluator's senses are determined according to the contents of these parameters. A predetermined stimulus is applied to the stimulus, and the above parameters are adjusted according to the input operation of the evaluator who receives the stimulus. If you perform evaluation and perform the above manual operation based on the result,
The above cycle of simulation, stimulation, manual operation and parameter adjustment can be repeated until a satisfactory affective evaluation result is obtained. Moreover, the data output means
Since the parameters after adjustment are output,
It is possible to directly take in the satisfactory evaluation result as design data and reflect it in the vehicle design.

Therefore, according to the present invention, it is possible to perform a sensitive evaluation of vehicle characteristics without using a prototype vehicle, and to accurately reflect the evaluation result in vehicle design.

The above effects will be described in detail. First, design, layout, function, and
Since it is possible to evaluate the sensitivity to performance, it is possible to optimize the design study, evaluation, and verification by feeling before making a prototype. In addition, since it is possible to carry out evaluation and examination based on design and sensitivity in parallel and consistently, the efficiency of design and development can be improved. Furthermore, since the results of the sensibility evaluation / study on the design, layout, function, performance, etc. can be reflected / adjusted on the spot, it is possible to realize the time-continuous relative sensation evaluation for the design / prototype contents.

In particular, when the driving simulator for giving the evaluator a pseudo vehicle traveling sensation is provided as the "sensory stimulus imparting means" as described in claim 9, it is possible to perform dynamic operation during vehicle driving. Sensitivity evaluation can also be appropriately performed.

Then, the computer 12 calculates the adjustment amount of the corresponding adjustment parameter from the dial operation amount of the adjuster 18, and based on the calculation result and the evaluator data, the sensation and the stimulus applying amount which are the targets of stimulus application. It is supposed to be adjusted.

Therefore, the evaluator is the simulator 16

Next, an example of a sensitivity evaluation procedure using the simulation apparatus according to this embodiment will be described with reference to the flowchart shown in FIG.

First, step S1 (indicated by (1) in the figure).
The same shall apply hereinafter), and initial data for a cabin interior design model for vehicle interior space habitability design based on predetermined design requirements is created and input to a computer.

Next, in step S2, the values of the visual adjustment parameters set by the dial (material appearance / color pattern of interior materials, positions of pillars / roof / instrument panel, etc., position / opening size of sunroof, illumination) Position, degree of irradiation, etc.)
And the value of the auditory-related adjustment parameters set by the dial, signal processor, and equalizer (the degree of sound quality, volume, frequency component strength and weakness, etc.), and the value of the adjustment parameters related to the temperature and humidity feeling set by the dial ( (Temperature, humidity, air volume, wind direction, blowing position, etc.) and the values of odor-related adjustment parameters (type of fragrance, strength, etc.) set by switches, input dials, etc. are loaded into the computer.

On the other hand, in step S3, the position of the eyeball, the direction of the line of sight, and the posture of the evaluator are detected by the sensor attached to the head mounted display (HMD) and input to the computer.

Then, in step S4, the value of the adjustment parameter obtained in step S2 and the position / line-of-sight direction / posture of the evaluator obtained in step S3 are calculated by the computer using the vehicle interior space habitability design model.

Next, a twelfth embodiment of the present invention will be described.

FIG. 24 is a block diagram showing the structure of the simulation apparatus according to this embodiment.

As shown in the figure, this simulation device evaluates the phase angle characteristic (4W) of the four-wheel steering device (4WS).
A computer 12, a controller 14, and a simulator 1 are devices that allow an evaluator to experience a vehicle riding state for the purpose of (evaluation for prevention of vehicle sickness by S).
6. The controller 18 is provided, and the vehicle characteristics relating to the phase angle characteristic of 4WS are simulated with a plurality of parameters, and predetermined stimulus is applied to a plurality of senses of the evaluator according to the contents of these parameters. The above parameters are adjusted according to the manual operation of the evaluator who receives this stimulus, and the adjustment result is output as data.

The computer 12 is designed to simulate the vehicle characteristic relating to the phase angle characteristic of 4WS with a plurality of parameters.

In the computer 12, the parameters used for simulating vehicle characteristics consist of vehicle interior space design model data, vehicle motion calculation model data, evaluator data, and adjustment parameters. The design model data and the evaluator data are the same as in the first embodiment. The vehicle motion calculation model data is the same as in the fifth embodiment. On the other hand, as the adjustment parameter, the phase angle of 4WS (including the opposite phase) according to the traveling speed is set.

The computer 12 further sets the sensation and the amount of stimulus to be applied to the evaluator by the simulator 16 according to the contents of the input parameters, and sets the stimulus. The result is output to the controller 14. In addition,
In this embodiment, the sensation is given to the sensation, the visual sense, and the auditory sense.

The controller 14 controls the output of each simulator element constituting the simulator 16 based on the setting result.

The simulator 16 is a driving simulator which gives the evaluator a driving sensation, and includes a driving simulator main body 38, a projector type display 34, and speakers 2 arranged in front of and behind the evaluator.
2 and each of these simulator elements is adapted to apply a stimulus to each of the above senses with the amount of sensory stimulus input from the controller 14.

That is, by the driving simulator main body 38, the evaluator is put into a movable cabin equipped with a seat, a steering wheel, pedals, an instrument panel, a console and the like similar to an actual vehicle to make a cornering run, and based on the driving operation. Cabin speed, angular velocity,
Acceleration, angular acceleration, steering reaction force, pedaling force, and running sound are presented to the evaluator according to the phase angle of 4WS so that the evaluator can feel the feeling. Further, the projector-type display 34 presents images of roads, landscapes, etc. to the evaluator as a driving field of vision and appeals to the visual sense. Further, the speaker 22 presents an engine sound and a running sound for giving a realistic sensation to the evaluator so as to appeal to their hearing. A head-mounted display (HMD) may be used instead of the projector display to present the evaluator with a three-dimensional stereoscopic image of a road, a landscape, or the like as a driving view. In this case, pillars and instrument panels inside the cabin, bonnet outside the cabin, trunk lid, etc. are simultaneously presented to the evaluator as a driving view.

The structure of the adjuster 18 is the same as that of the first embodiment. The evaluator will adjust the phase angle of 4WS with a dial or the like according to the traveling speed so as not to cause vehicle sickness due to 4WS.

Next, an example of the sensitivity evaluation procedure using the simulation apparatus according to this embodiment will be described with reference to the flowchart shown in FIG.

First, in step S1, initial data for a vehicle model and a vehicle exterior environment image model having predetermined characteristics are created and input to a computer.

Next, in step S2, the value of the adjustment parameter set by the input dial (4 depending on the traveling speed is set).
(WS phase angle data) is loaded into the computer.

On the other hand, in step S3, the position of the driver (evaluator) is measured by the sensor mounted in the cabin and input to the computer.

In step S4, driver's steering, accelerator, brake and other driving operations are measured and input to the computer.

Then, in step S5, the computer calculates the vehicle behavior according to the driving operation of the driver obtained in step S4, using the vehicle model and the data obtained in step S2.

Next, at step S6, the computer calculates the image data of the environment outside the vehicle (road, landscape, etc.) according to the position of the driver obtained at step S3 and the vehicle behavior obtained at step S5. .

Then, in step S7, a controller such as a projector is provided with a video control command value based on the data obtained in step S6.

Further, in step S8, an image is presented to the driver by the projector or the like based on the command value given in step S7.

On the other hand, in step S9, the controller of the driving simulator is caused to sense the driving sensation such as the cabin speed, angular velocity, acceleration, angular acceleration and steering reaction force, pedal depression force, and running sound based on the vehicle behavior obtained in step S5. The control command value of is given.

Then, in step S10, the driving simulator imparts each driving feeling to the driver based on the command value given in step S9.

Next, in step S11, the driver drives the driving simulator (performs cornering).

Then, in step S12, the driver
While performing the driving in step S11, the sensitivity evaluation is performed with respect to the feeling (sickness of vehicle) and the field of vision during cornering.

If the evaluation is not good, step S13.
Then, the driver changes the 4WS phase angle according to the speed with the input dial based on the evaluation result. Then, step S2 and subsequent steps are repeated until the evaluation is improved.

On the other hand, if the evaluation is good, step S14.
Then, the data of the 4WS phase angle according to the optimized traveling speed is written in the storage device, the recording medium in the format of the design specification, and is output to the printing device, the display device, etc., if necessary, and the process ends in step S15. .

As described in detail above, according to this embodiment,
In the computer 12, the vehicle characteristic related to the phase angle characteristic of 4WS is simulated with a plurality of parameters, and the sensation and the stimulus amount to be stimulated are set according to the contents of these parameters, and the controller 14 controls the output. In the simulator 16, the stimulation is applied to the plurality of senses of the evaluator according to the setting contents, and the adjuster 18 adjusts the parameter according to the manual operation of the evaluator who receives the stimulation. Since the adjusted parameters are output from the computer 12, the following effects can be obtained.

That is, 4WS at the corner (at the time of opposite phase)
When the vehicle is being driven, the travel speed and the anti-phase angle (depending on the cornering radius) may cause a difference between the bodily sensation and the visual sense, resulting in discomfort or car sickness. In the past, it was not possible to evaluate whether or not the 4WS characteristic does not cause discomfort and causes car sickness unless the prototype vehicle is actually driven. On the other hand, in the simulation apparatus according to the present embodiment, by combining the driving simulator technology and the computer graphics technology, it is possible to evaluate the 4WS characteristic (phase angle adjustment) without using a prototype vehicle. Further, in the present embodiment, each parameter related to the 4WS characteristic is adjusted and changed while matching with the sensation, and the 4WS characteristic is not uncomfortable and does not cause car sickness while performing continuous continuous relative sensory evaluation. Therefore, it is possible to obtain the optimum design value of the 4WS phase angle that does not cause vehicle sickness without feeling uncomfortable. Further, the obtained design data can be used as it is as information for drawing / NC processing.

As described above, according to this embodiment, the sensitivity evaluation of the phase angle characteristic of the 4WS for prevention of vehicle sickness due to the 4WS can be performed without using a prototype vehicle, and the evaluation result can be obtained. It can be accurately reflected in the vehicle design.
