Brake activation through time-out

If a waiting time for the brake activation > 0 s is set in C02593

, the time monitoring is active, i. e. the

brake at the latest is activated for application after the waiting time has elapsed, even if the actual

speed value is still above the threshold for the brake activation set in C02581

.
