VBOX TEST SUITE (VTS) - COASTDOWN TEST PLUG-IN
Coastdown
VBOX Coastdown is a test plugin pre-loaded into VBOX Test Suite. You can choose between three test standards within the plugin, the European WLTP GTR15, the American SAE J2263 and the Brazilian ABNT NBR 10312.
SAE J2263
The US SAE J2263 Coastdown standard has until now required highly complex post-processing work, as well as demanding the use of onboard anemometer readings. The VBOX Test Suite Coastdown plugin integrates the wind speed via an analogue signal into the VBOX itself, and produces a road force measurement that completely removes the need for heavy-duty, time consuming calculations after the track tests have been completed.

WLTP GTR15
Coast down testing to the new European WLTP GTR15 standard has pass criteria not just from a start to end speed, but also in 10 km/h decrements and in opposing directions. (For instance, a 115 km/h - 15 km/h test requires an overall result,, as well as from speeds of 115 km/h - 105 km/h, 105 km/h - 95 kmh and so on – with each section having to fall within a 3 % tolerance to pass). Test Suite automatically grades each section, of each individual run, and stitches each of the full runs together to form a comprehensive set of results.

VBOX Test Suite calculates the total coastdown time and automatically excludes any non-valid runs. It automatically calculates the CVf'0 and CVf'2 values.
