Debut of the Second-generation Riding Simulators
The world's first riding simulators, mass-produced in 1996,
were put to practical use in the training curriculums of motorcycles
as an educational equipment on safe driving and are found
to be useful for the improvement of capacity to predict critical
situations, thus effective for the prevention of accidents.
|Features of New Riding Simulators|
|A entirely new model was developed, maintaining the high performance
spoken highly of the previous model, for the purpose of further
spread and improvement in functions. Outstanding features as
compared with the type before are "substantial reduction in
price", "riding unit easily changeable to scooter", "lightweight
and compact design" enabling easy installation, "images and
sound with improved feeling of appearance on the scenes" and
"completion of various educational functions".
|Thoroughly Compact Design|
| As compared with the previous model, the new model is made
compact by 600mm in length, 140mm in width and weight reduced
to a half. Contributed largely to this is the reduction of the
number of parts by re-design of the motion base, which reproduces
the motion of motorcycles, and the aluminum cast projector box.
As for the structural layout, the adoption of a projector equipped
with short focus lens of new design and the optimum layout in
the box of control system equipment has enabled to achieve compact
project box despite of enlarged screen.
|Substantial Change in Movable Systems|
|The largest change was made in the motion base, movable unit.
Exclusive motors and reduction box were used before for the
roll or the tilt in the direction of left and right and for
the pitch or the tilt in the direction of fore and aft. Highly
rigid bearings and sturdy frame were required for this because
of large load imposed since the motor for roll had to move the
motor for pitch. In the new model, the same pitch and roll centers
were maintained by arranging bearings at the locations where
exclusive motors and reduction box were positioned before, and
similar roll and pitch motions were reproduced by locating drive
motors on the left and right of the front. As the result, a
substantial reduction of weight was achieved.
|Roll and pitch shafts are arranged between a T-shaped base
frame and the body frame. Since the positions of shafts largely
affect the bodily feeling on riding, layout is so made to agree
with the shaft centers before. An arm is arranged in the front
of body frame to hold the hollow servomotor. A hollow motor
proper is connected to the arm through a universal joint. The
shaft of ball screw is connected to the base frame with the
universal joint. As the result, the body is supported at three
points to determine its posture. With the motors on the left
and right moving up and down in the same directions, pitching
is reproduced. Rolling is reproduced with the motion of motors
on the left and right in opposite directions.
| Shown on the former operation screen was the composite of
speed and the operations of rider like braking and the images
of vision in the front. In addition to them, bird-eye views
and a message window were added in the new model. Locations
selected at one's option can be magnified and shown on the map,
and traffic conditions in surroundings can be confirmed. The
message window, on the other hand, will show real time the area
presently driven through and the reasons for accidents (collision,
brake lock, etc.)
Evolution of Operation Screen
| By a regeneration function called multi-eye, images can be
reproduced from various points of views after completion of
training, so it can be effectively utilized for guidance. Furthermore,
a function was added to the multi-eye to measure and display
the distance between two optional points during replay and temporary
stop, to enable easy measurement by clicking the screen.
