Abstract: A position calibration system and method are disclosed, in which a control unit is provided to control a positioner sensing module to scan a circular positioner provided on a positioning substrate in a first direction and a second direction so as to acquire midpoints of two scanned line segments and acquire an intersection of lines extending from the two center points in a direction perpendicular to the first and the second directions as a calibration reference point, which correspond to a centroid (a center) of the circular positioner. The calibration reference point functions as a reference point for positioning the positioning substrate with respect to the positioner sensing module and is stored in a memory unit. The calibration reference point can be used as a positioning point during installation of a machine and can also be used for calibration of a position of the machine.

Abstract: The present application discloses a motor controller, a motor control method and a computer program product for vehicle assist control. An assist torque command for a motor device to perform vehicle assist control is generated according to an execution command of a vehicle assist determination unit and a rotor position signal and a rotor speed signal of a motor device. An original position signal of the motor device and the rotor position signal are calculated, and a position ratio calculation is performed to generate a front-order torque command. A torque damping command is generated according to the speed ratio calculation based on the rotor speed signal, and is calculated with the front-order torque command to generate an assist torque command. Thus, position information of the rotor of the motor device can be directly used in the calculation and speed information is at the same time used for an assist calculation, thereby preventing an error and solving the issue of sliding during parking.

Abstract: The present invention provides a probe apparatus, which comprises a signal transmission device, a probe, and a bottom fixing device. The signal transmission device includes a first transmission part and a second transmission part. An end of the probe is connected electrically below the second transmission part. The bottom fixing device is disposed below the signal transmission device. An end of the bottom fixing device includes a first penetrating hole and a first recess is disposed below the end. The probe passes through the first penetrating hole of the bottom fixing device. The probe is located in the first recess. The bottom fixing device reinforces the mechanical strength of the signal transmission device so that the width of the signal transmission device can be reduced. Thereby, the benefit of high-density arrangement of the probe apparatus can be achieved.

Abstract: An automatic mounting and demounting device and system for a motor testing platform, adapted to enable a control host to control automatic mounting and demounting between an axle of a motor under test and an axle of a testing apparatus, includes a mobile platform and a positional information sensing member. The control host controls the mobile platform according to positional information generated by the positional information sensing member, such that a carrier for carrying the motor under test is automatically driven to a corresponding position to thereby effect alignment and connection or separation of the axle of the motor under test and the axle of the testing apparatus. Therefore, preparation for the motor dynamics testing is automatically carried out effectively and correctly, thereby reducing the time and manpower required for testing-related preparation.
