To continue turn control even if any one of load sensor is failed.SOLUTION: A turn control method of an inverted two-wheel vehicle for performing turn control on the basis of output values of at least two load sensors which are arranged separately in left and right directions in order to detect load ratios of an occupant in left and right direction who boards on a step part 21 arranged at a bogie part 2 includes: a total sum calculation step (S120) for calculating a total sum of the output values of at least the two load sensors; and an abnormal-time turn control step (S150) for performing the turn control when the output value of the specified load sensor as any one of the load sensors is abnormal (S130: YES). In the abnormal-time turn control step (S150), the output value of the failed load sensor is estimated on the basis of the total sum and the output value of the other load sensor which is in a normal operation (S152).SELECTED DRAWING: Figure 5
