TEST TRACKS

WABCOTEST TRACKSWABCO is the only commercial vehicle industrySUPPLIER that operates THREE privatelyowned TEST TRACKS.Road and commercial vehicle safety standards continue to become increasingly stringent worldwide.New and existing commercial vehicle systems – such as electronic braking, driver assistance and stabilitycontrol – can further support vehicle drivers and improve safety.Alongside software-based testing, a key aspect of WABCO’s development process continues to takeplace on test tracks. Each track is specially designed for commercial vehicle trials. It provides optimalconditions to test and refine new systems in order to meet tomorrow’s demanding customer and regulatoryrequirements.Rovaniemi Test Track at the Arctic CircleWABCO opened its test track locatedat Rovaniemi, Finland in 1988.The winter test program at Rovaniemiinvolves extreme conditions such as icy,snow-covered roads and subfreezingtemperatures. The test track featuresa modern workshop with four lanes aswell as a closed area for confidentialevaluation of customer prototype trucksand buses.In a typical winter test cycle, WABCOengineers and technicians loggedapproximately 1,300 person-daysconducting tests. This activity includedtesting of 25 WABCO-owned vehiclesas well as joint testing of trucks andbuses from leading commercialvehicle manufacturers.Track Factsn Brake lane on asphalt is 350 meters(383 yards) and 100 meters (328feet) heatedn Brake lane with ice is 350 meters(383 yards)n Dynamics area with diameter of280 meters (306 yards) and lengthof 1.35 km (0.84 mile)December 2008

Jeversen Test Track near Hanover, GermanyOpened in 1995, WABCO’s “ErichReinecke Test Track” is locatednorth of Hanover, Germany, nearbythe company’s center for research,development and manufacturing.In 2008, WABCO opened a vehicledynamics extension at this track,expanding its global testing capabilities.WABCO’s test track extension providessafe and efficient capabilities for dynamicand stability testing on trucks, truck/trailer combinations and buses at highspeeds. It offers optimum developmentconditions for the company’s innovativestability control systems such aselectronic braking systems (EBS),roll stability support (RSS) and electronicstability control (ESC).WABCO pioneered ESC for commercialvehicles in 2001 and has continuedto drive ESC innovation ever since.Furthermore, the European Union willmandate ESC technology for new heavyclass commercial vehicles starting in2012, resulting in a sharp increase inthe number of tests to be conducted atWABCO’s proving ground in Germany,as ESC systems need to be adaptedand certified for different ranges ofcommercial vehicle models.Track Factsn Oval of 2,000 meters (1.24 miles)with two steep curves and two 550meter (602 yards) long straightsections consisting of differentroad surfacesn Circle with an inside radius of100 meters (328 feet) and aroad width of 30 meters (98 feet)n Dynamics area of 56,000 squaremeters (67,000 square yards) withdiameter of 220 meters (241 yards)Chennai Test Track in IndiaOpened in 2001, the Chennai test trackis a 200-acre (0.31 square mile) stateof-the-artfacility located in southeastIndia. There are different surfaces forbraking such as high friction asphalt andlow friction basalt. Different testing canbe conducted on dry and wet surfaces,including ceramic which is ideal fortraction control testing. The Chennai testtrack also features an on-site workshopand viewing gallery for customerdemonstrations.Track Factsn Straight line of 1.35 km (0.84 mile)n Width of braking area is70 meters maximum (77 yards)n Length of asphalt is 325 meters(356 yards); blue basalt is225 meters (246 yards)and ceramic is 110 meters(120 yards)© 2008 WABCO All rights reserved
