Abstract

A vehicle-mounted device includes an analysis unit and a control unit. The analysis unit detects an insertion blade on the basis of sensing information acquired from a spatial recognition device, and calculates an insertion distance indicating a distance by which the detected insertion blade is inserted into an insertion target. The control unit performs an amount-of-insertion determination to determine whether or not the insertion distance is in a predetermined range.

First claim

1 . A vehicle-mounted device comprising:
an analysis unit that detects an insertion blade on the basis of sensing information acquired from a spatial recognition device, and calculates an insertion distance indicating a distance by which the detected insertion blade is inserted into an insertion target; and a control unit that performs an amount-of-insertion determination to determine whether or not the insertion distance is in a predetermined range.

2 . The vehicle-mounted device according to claim 1 , wherein the analysis unit calculates the insertion distance on the basis of a distance indicated by the sensing information, the distance being a distance from a position of a base of the insertion blade or the vicinity thereof to an insertion portion of the insertion target.

3 . The vehicle-mounted device according to claim 1 , wherein the analysis unit calculate the insertion distance on the basis of a timing at which the insertion blade has reached a position indicated by the sensing information, the position being a position of the insertion portion of the insertion target, and a velocity of a vehicle in which the vehicle-mounted device is mounted.

4 . The vehicle-mounted device according to claim 1 , wherein the analysis unit calculates the insertion distance on the basis of a difference between a distance from the spatial recognition device to the insertion surface when the insertion blade has reached a position indicated by the sensing information, the position being a position of the insertion portion of the insertion target, and a distance from the spatial recognition device to the insertion surface after the insertion blade has reached the position of the insertion portion.

5 . The vehicle-mounted device according to claim 1 , wherein the control unit changes an output based on the amount-of-insertion determination, on the basis of the insertion distance.

6 . The vehicle-mounted device according to claim 1 , wherein the control unit causes a warning to be output on the basis of a result of the amount-of-insertion determination and a traveling direction of a vehicle in which the own device is mounted.

7 . A cargo handling machine comprising the vehicle-mounted device including:
an analysis unit that detects an insertion blade on the basis of sensing information acquired from a spatial recognition device, and calculates an insertion distance indicating a distance by which the detected insertion blade is inserted into an insertion target and a control unit that performs an amount-of-insertion determination to determine whether or not the insertion distance is in a predetermined range.

8 . A control circuit that detects an insertion blade on the basis of sensing information acquired from a spatial recognition device, and determines whether or not an insertion distance indicating a distance by which the detected insertion blade is inserted into an insertion target is a predetermined range.

9 . A control method comprising:
detecting, by an analysis unit, an insertion blade on the basis of sensing information acquired from a spatial recognition device, and calculating an insertion distance indicating a distance by which the detected insertion blade is inserted into an insertion target; and performing, by a control unit, an amount-of-insertion determination to determine whether or not the insertion distance is in a predetermined range.

10 . A non-transitory computer readable medium which stores a program causing a computer to:
detect an insertion blade on the basis of sensing information acquired from a spatial recognition device; calculate an insertion distance indicating a distance by which the detected insertion blade is inserted into an insertion target; and perform an amount-of-insertion determination to determine whether or not the insertion distance is in a predetermined range.
