in a manner befitting
a world-leading
systems supplier.
JTEKT, as a total supplier of automobile components and systems,
is making various efforts to provide many products to our customers.
Iga Proving Ground
Enables Testing /
Evaluations Simulating Roads Worldwide
Fully utilizing our knowledge as a world-leading systems supplier, JTEKT conducts driving evaluations and analyses of products installed in vehicles.
We exhaustively pursue the highest standards in product safety and operation on a test course capable of simulating various road and weather conditions around the world.
As a total systems supplier, our highest value is to provide our customers with products that deliver outstanding performance and the best quality that help to make automobiles that are more than just fun to drive.
1 Main Track
The main track, the most distinctive course at this proving ground, is a combination of winding and straight courses that enable full circuit-like laps to be driven.
The straight is 1.0km-long including acceleration/deceleration zones and was designed for evaluations at up to 120km/h in a straight 400m evaluation zone after accelerating from the west parking area.
The leftmost lane features high-tech paving for excellent Water drainage and lane-departure warning rumble strips (raised sections on the road surface), enabling evaluations of noise and the electronic control system.
The winding course features numerous corners and is designed as an uneven course that enables the evaluation of vehicle front/rear load shifting to be factored into test conditions.
Its main application is testing that evaluates overall vehicle motion.
2 Dynamics Pad
The dynamics pad is an area used to analyze forces acting on the vehicle. Positioned in the center of the main track, it is designed as a spacious area, roughly the same size as Tokyo Dome. Its main application is tests that require versatility in implementation, such as turning in circles and slalom driving. In addition, using the acceleration zone that branches off from the straight, it is possible to test vehicle behavior close to the limits of vehicle performance.
Also, low μ surface simulating compacted snow or icy road conditions enables driving evaluation on slippery road conditions.
3 Noise Evaluation Course
The noise evaluation course features various special courses including a 150m-long stone-block paved course and wave, rope, cobblestone, rumble-strip and cracked-surface courses. These special courses produce large differences in the size and frequency of input from the road surface. Accordingly, they are mainly utilized to check noise generation when vehicles receive road-surface input derived from different conditions.
Given the recent advances realizing extremely quiet vehicle interiors, a wide array of special roads have been incorporated to ensure that manufacturers can take measures to secure adequate sound quality.

Administration/
Maintenance Building
The entire proving ground is managed from this building using surveillance cameras and other equipment to ensure all vehicle testing is conducted safely and efficiently.
Facilities allow servicing of up to five vehicles simultaneously including facilities for pre-test servicing of test vehicles and measurement checks. Eco-conscious measures have also been taken, such as the use of LED lighting, the installation of solar panels on all roof surfaces and the wide use of thermal-insulation materials.
