Step S330 is according to the time interval current and that move distance calculated current collision and collided last time last time.
This deducts the poor of move distance last time apart from the current move distance that processing unit will be stored in it, and the movement velocity that is provided with divided by automatic cleaning apparatus before the cleaning can obtain this time interval again.
Particularly, current collision is the n time collision, and then collision last time is n-1 collision, and its move distance is respectively 1
nWith 1
(n-1)The time, the n time time interval Δ T then
n=(1
n-1
(n-1))/v.Wherein, n is the integer more than or equal to 1, and v is the preceding movement velocity that is provided with of cleaning.
