A motor vehicle according to the invention comprises an internal combustion engine having an output shaft and is capable of outputting a driving force for driving said motor vehicle, a driving force transmission mechanism linked to the output shaft of the internal combustion engine and to an axle, and, in at least a predetermined low vehicle speed range, transmits a driving force corresponding to a rotation speed of the internal combustion engine to the axle, a driving force demand detection unit detecting a driving force demand corresponding to a driver's operation, a vehicle speed measurement unit measuring a vehicle speed, a road gradient detection unit detecting a road gradient, and a low-speed drive control module that, when the measured vehicle speed is not higher than a preset reference vehicle speed included in the predetermined low vehicle speed range and when the detected road gradient is not less than a preset reference gradient, sets a target driving force for constant-speed driving of said motor vehicle at a target vehicle speed, which is set to be not higher than the preset reference vehicle speed, based on the detected road gradient, when the detected driving force demand is not less than the target driving force, said low-speed drive control module controlling operation of the internal combustion engine to output the driving force demand, and when the driving force demand is less than the target driving force, said low-speed drive control module controlling the operation of the internal combustion engine to output the target driving force. |
