Abstract

The invention relates to a method for operating an autonomous industrial truck (1), having the following method steps: determining, by means of a measuring apparatus (6) of the autonomous industrial truck (1), whether the industrial truck potentially hits at least one obstacle (7) on the basis of the present movement of said industrial truck (1), determining that point (14) of the industrial truck (1), and determining a maximum velocity for the present movement of the industrial truck (1) on the basis of the determined distance (d), with the result that the industrial truck reliably comes to a standstill in front of the obstacle (7) on the basis of possible braking of the industrial truck (1).

Claims

1. A method for operating an autonomous industrial truck, having the following method steps:

By means of a measuring apparatus (6) of an autonomous industrial truck (1) determining whether the industrial truck potentially collides with at least one obstacle (7 on the basis of the present movement of said industrial truck (1),

Determining those points (14) of the industrial truck (1) at which the obstacle (7) will potentially be hit,

Determining the distance (d) between the obstacle (7) and the point (14) of the industrial truck (1), and

Determining a maximum velocity of the present movement of the industrial truck (1) on the basis of the determined distance (d), with the result that the industrial truck (1) reliably comes to a standstill in front of the obstacle (7) on the basis of possible braking of the industrial truck (1).
