Abstract
A mining vehicle is provided, which is capable of appropriately recognizing a condition of a traveling road in front of the vehicle, preventing an obstacle on a roadside from being erroneously detected by a distance detector, and controlling the speed of the vehicle in a stable manner even when the vehicle is approaching a curved portion of the road from a linear portion of the road. The mining vehicle that travels on a transport road of a mining site includes: a minimum roadside distance determining unit; a traveling status calculator configured to calculate traveling status of the vehicle and a turning radius of the vehicle; a roadside distance calculator configured to calculate a roadside distance between the vehicle and a roadside of the transport road; a roadside distance selector configured to select and output a minimum roadside distance if the vehicle is in a rectilinearly traveling state and select and output the roadside distance calculated with the roadside distance calculator if the vehicle is in a turning state; a detected distance limiter configured to disable a signal representing the distance, detected with the distance detector, between the vehicle and the object and the relative speed if the distance between the vehicle and the object is larger than a distance represented by a signal selected and output from the roadside distance selector; and a vehicle speed controller configured to control the speed of the vehicle on the basis of a signal output from the detected distance limiter.
