A mobile vehicle comprising: one or more wheels (30, 31, 32, 33); a sensor configured to detect a position of a target to be followed; and a controlling section configured to set a target point based on a detection result of the sensor and control the one or more wheels ( 30, 31, 32, 33) to move the mobile vehicle toward the target point such that the mobile vehicle follows the target to be followed, characterized in that the controlling section is configured to store in a memory a plurality of positional data of the target to be followed, each positional data has been detected by the sensor at predetermined time intervals, determine whether there is a change point ( Pc) at which a traveling direction of the target to be followed has changed based on the detection result of the sensor, set the target point to the target to be followed when there is no change point, and set a target point ( Pt) based on the change point ( Pc) when there is a change point, and determine that the change point is a position that corresponds to one of the stored positional data and meets one or more conditions, the controlling section is further configured to define a coordinate system in which a directional axis from the mobile vehicle toward the target to be followed is a first axis, and a directional axis orthogonal to the first axis is a second axis, and the one or more conditions include: a condition that a value of a coordinate on the first axis is greater than zero on the coordinate system, a condition that an absolute value of a coordinate on the second axis is greater than a threshold on the coordinate system, a condition that an absolute value of a coordinate on the second axis is greatest on the coordinate system, and a condition that a distance from the mobile vehicle is greater than or equal to a predetermined distance ( Dn). one or more wheels (30, 31, 32, 33);
