A coupling angle detection device acquires a shape information of a target member having a prescribed shape and installed in a first vehicle by a shape information acquisition unit installed in a second vehicle and detects an angle formed by a direction specified based on a prescribed condition from the acquired shape information of the target member and a front-rear direction of a vehicle body of the second vehicle that is held, as a coupling angle between the first vehicle and the second vehicle. The target member is installed in the first vehicle such that the specified direction fits a front-rear direction of a vehicle body of the first vehicle.

Coupling angle detection device for combination vehicle, combination vehicle, and coupling angle detection method for combination vehicle

A drive control system (S) includes a measurement portion () configured to detect an obstacle (R) in a transportation vehicle (T), and a load collapse determination portion () configured to acquire an arrangement of a transportation target (C) loaded on the transportation vehicle (T) based on measurement data of the measurement portion () to determine a load collapse of the transportation target (C) based on a change in the arrangement over time.

Drive control system

Provided is a weight estimation system (S) including: a change amount calculation device () which acquires a height of a loading platform (N) before loading a vehicle and a height of the loading platform (N) after loading the vehicle and calculates an amount of change between the heights of the loading platform (N) between before and after the loading; and a loaded weight estimation device () which estimates a loaded weight on the basis of a correlation between the amount of change and a loaded weight stored in advance.
