Donghai proving ground

Circular area that includes parking area, meeting room, run-up, acceleration track and testing area. The circular area can be used for braking maneuvers, lane changes, driving in a circle or slalom driving. For driving in a circle, markings are provided with different radii. In addition, the area has markings for a handling course.

• Profile: asphalt / optional: wet surface (250 m x 85 m)
• Acceleration track: 1,500 m
• Diameter: 300 m

The slopes are intended for testing traction control systems (TCS) and downhill braking. There are uphill slopes with gradients of 10%, 15%, 20% for different μ-split constellations available. The slope with a gradient of 30% provides a special slope for tilting the vehicle.

• Length: 25 m
• Gradient: 10%, 15%, 20%, 30%

Brake tests can be carried out on the floodable tracks with various surfaces and friction coefficients. The proving ground Donghai provides two different brake measurement tacks.

Brake measurement track 1

• Aquaplaning basin
• Concrete
• Concrete (polished)
• Asphalt
• Ceramic tiles
• Asphalt
• Checkerboard

Brake measurement track 2

• Basalt
• Asphalt
• Ceramic tiles
• Asphalt

On handling course, the vehicle’s handling can be tested in extreme curvy situations. For this purpose, our handling courses provide a variety of different curve radii. To provide the wet asphalt surface for wet handling, sprinklers are installed on both sides of the inner lane. Many roads connect the inner lane with the outer lane, thus the test route can be flexibly planned according to the customer needs.

• Width: 7 m
• Number of lanes: 2
• Number of curves: 28
• Outer lane: 1,200 m
• Inner lane: 1,600 m, 80% of surface can be watered

On rough roads a vehicle’s suspension and electronics undergo a hard test.

Rough roads 1

• Number of lanes: 6
• Profile: Belgium road / Haimen road / washboard / road block / spanish bumps / sinus wave / cobble stone

Rough roads 2

• Number of lanes: 2
• Length: 150 m
• Profile: sand and stone / gravel
