Division 4.4.3 System boundaries

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 (v_min in Figure 1);

Minimal stop time:

The minimum time after every coasting deceleration to a standstill or constant speed phase is 2 seconds ( $t_{\mathrm{stop}}^{\min }$ in Figure 1);

Minimum time for constant speed phases:

The minimum time for constant speed phases after acceleration or coasting deceleration is 2 seconds ( $t_{\mathrm{const}}^{\min }$ in Figure 1). For technically justified reasons this value may be increased.
