摘要： PURPOSE:To improve curve passing function by steering a logic by using the torque difference between right and left wheel circumferences so as to eliminate the relative angle between the direction of rotation of an independent wheel and the tangent of a rail. CONSTITUTION:In a driving bogie having wheels 3a, 3b that can be rotated independently, the relative displacement in the direction of a normal 15 between the rail and each sensor 1a, 1b, 1c, and 1d, is measured, and an angle formed by the direction 13 of the wheel rotation and the polarization of the wheel in the horizontal direction on the rail surface are calculated based on the measurement information. The relative angle between the direction 13 of wheel rotation and the tangent 14 of the rail can be eliminated by calculating the torque difference generated by electric motors 17a, 17b and by controlling the torque of each electric motor, while the curve passing function can be improved by correcting the horizontal polarization of the wheels 3a and 3b in relation to horizontal rails 7a and 7b, caused by the structure of an independent wheel.

摘要： PROBLEM TO BE SOLVED: To provide an acceleration-detecting apparatus which can easily detect a failure. SOLUTION: A pair of acceleration sensors provided at an acceleration- detecting apparatus main body 1 are arranged with respective sensitivity axes inclined by inclination angles θA, θB to a horizontal axis H. An output signal α1 corresponding to a horizontal acceleration αH and an output signal α2 corresponding to a vertical acceleration αV are operated at an operation circuit. When an object an acceleration of which is to be detected stands still, the output signal α2 corresponding to the vertical acceleration αV is compared with the vertical acceleration αV which is to be obtained at the normal time because of a gravitational acceleration, so that a failure of the acceleration- detecting apparatus is detected.
