The invention provides a utility vehicle, and a control method for the utility vehicle. This utility vehicle comprises: a first control system for controlling the travel of the utility vehicle; a second control system which uses set information to control travel of the utility vehicle via the first control system; a first communication line which is used for communication between the first control system and the second control system; and a second communication line for transmitting information from the second control system to the first control system. The second control system generates information to control the engine of the utility vehicle and information to control a braking device and, using a mode that is different to the transmission mode of information used by the first communication line, transmits this information to the first control system via the second communication line.
