Abstract
Upon satisfaction of three predetermined conditions that 1) a straight-ahead travel instruction has been given, 2) an actual number of motor rotations is less than a target number of motor rotations and 3) a motor control signal produced to bring the actual number of motor rotations closer to the target number of motor rotations has reached a predetermined upper-limit output value, a downward motor-rotation correction process is performed repeatedly to progressively reduce the target number of motor rotations or to reduce the upper-limit output value of the motor control signal until the respective actual numbers of rotations of the left and right motors to substantially coincide with each other. -33-
