# Commission Implementing Decision (EU) 2017/1402 of 28 July 2017 on the approval of the BMW AG engine idle coasting function as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance), Division 4.4.3: System boundaries

Extent: E+W+S+N.I.

(a) Lower speed limit for coasting:
The coasting mode shall be disabled at a coasting speed of 40 km/h by engaging the brake. At this point, a coast down curve is followed by a deceleration ramp as described for the NEDC-profile (vmin in Figure 1);
(b) Minimal stop time:
The minimum time after every coasting deceleration to a standstill or constant speed phase is 2 seconds ( t stop min in Figure 1);
(c) Minimum time for constant speed phases:
The minimum time for constant speed phases after acceleration or coasting deceleration is 2 seconds ( t const min in Figure 1). For technically justified reasons this value may be increased.
