A travel vehicle includes: a vehicle having a travel device and a vehicle body supported by the travel device; a steering device provided to the travel device; a steering angle detection device that detects detected steering angle data of the steering device; an attitude detection device that detects attitude data of the vehicle body; a travel speed detection device that detects travel speed data of the travel device; a turn data calculation unit that calculates turn data of the vehicle body based on the attitude data and the travel speed data; and a steering angle data correction unit that calculates first correction data on the detected steering angle data based on the detected steering angle data and the turn data.

Travel vehicle and method for controlling travel vehicle

Provided is a transporter vehicle including: a vehicle; an object detection device that detects an object at a front side of the vehicle; a collision determination unit that determines a possibility of a collision with the object based on a detection result of the object detection device; a process system that performs a process for reducing damage caused by the collision; a control unit that outputs a signal for reducing the damage caused by the collision to the process system based on a determination result of the collision determination unit; a time point data acquisition unit that acquires time point data in which the signal is output from the control unit; and an output unit that outputs process history data indicating at least a state of the process system. The output unit outputs the time point data and the process history data in association with each other.

Transporter vehicle, dump truck, and transporter vehicle control method

A transporter vehicle includes: a vehicle; a vessel that is provided in the vehicle; a traveling state detection device that detects a traveling state of the vehicle; an object detection device that detects an object in front of the vehicle; and a collision determination unit that determines a possibility of collision with the object based on a loading state of a load of the vessel, a detection result of the traveling state detection device, and a detection result of the object detection device.

Transporter vehicle and transporter vehicle control method

A transporter vehicle includes: a traveling device changing a traveling direction so that one state of a linear movement state and a non-linear movement state changes to the other state thereof; a setting unit setting a determination value related to a change amount in the traveling direction from the linear movement state; a collision prevention system including an object detection device detecting an object in front of the vehicle and a collision determination unit determining a possibility of a collision with the object based on a detection result of the object detection device, the collision prevention system performing a process for reducing damage caused by the collision with the object; and an invalidation unit invalidating at least a part of a process of the collision prevention system based on the determination value and a detection value of the change amount in the traveling direction from the linear movement state.

A transporter vehicle includes: a vehicle; an object detection device which includes a detection area at a front side of the vehicle and detects an object at the front side of the vehicle; a process system capable of performing a process for reducing damage caused by a collision; a specific detection area setting unit which sets a specific detection area having a width of a first dimension in a width direction of the vehicle and a length of a second dimension in a traveling direction of the vehicle in the detection area; a collision determination unit which determines whether an object exists in the specific detection area based on a detection result of the object detection device; and a control unit which outputs a signal for reducing damage caused by the collision to the process system based on a determination result of the collision determination unit.
