摘要： PROBLEM TO BE SOLVED: To more properly determine an off-abnormality state in which some switching elements making up an inverter are kept off to disable operation at the occurrence of slippage. SOLUTION: When a drive wheel idles to cause slippage, it is determined that a post-boosting voltage VH applied to an inverter has changed suddenly (step S180).

摘要： PROBLEM TO BE SOLVED: To accurately detect the abnormality of an inverter in a motor driving system which has an AC motor capable of switching its control mode.SOLUTION: An offset F/B processor 300 corrects each phase voltage command, based on an offset correction computed from each phase motor current. A control mode determiner 260 performs switching between a PWM control mode and a rectangular-wave voltage control mode, according to the operating conditions of an AC motor M1. An abnormality detector 400 determines whether a state that an offset F/B integration term computed by PI calculation with the offset F/B processor 300 exceeding threshold has continued for a specified time. When it is determined that the state of the interval over the threshold has continued over a specified interval, the detector detects that an inverter 14 is abnormal. The abnormality detector 400 corrects the threshold in the direction of increase, when it is determined that the changeover of the control mode is required, as well as when the change in torque or the change in revolution at a specified value or over is detected in the AC motor M1.

摘要： PROBLEM TO BE SOLVED: To detect a fault in an inverter, which supplies an AC motor with a drive current according to the voltage phase of the voltage of rectangular waves, based on the voltage phase of the voltage of the rectangular waves calculated by a rectangular wave controller. SOLUTION: A fault detecting unit determines whether the voltage phase ϕv of the voltage of the rectangular waves calculated by a rectangular wave voltage control unit and the phase ϕlimit of a limiter coincide with each other or not (S300).

If the fault counter exceeds a predetermined fault determination time (YES in S320), the detecting unit determines an abnormal state where an open failure occurs in the inverter (S330).

摘要： PROBLEM TO BE SOLVED: To provide a motor driving device that enables the enhancement of the efficiency of a motor and stable vibration damping control. SOLUTION: A torque command used for the computation of a voltage command for a step-up converter is generated by adding vibration damping torque Tcct to target driving torque. A target value Tcct* of the vibration damping torque Tcct is set according to the state of a relevant vehicle detected based on input signals from various parts of the vehicle regardless of a fluctuation component of number of revolutions contained in the number of revolutions of a motor. When the target value Tcct* of vibration damping torque is increased in correspondence with change in the state of the vehicle, the vibration damping torque Tcct is increased according to a rate of increase set according to the rate of change in the band of fluctuation in the vibration of the vehicle. This makes it possible to avoid an insufficiency of output torque and further prevent a voltage command from being uselessly set higher than motor driving voltage required to damp the vibration of the vehicle. As a result, the stability of vibration damping control can be ensured and further power loss in a voltage converter can be reduced. COPYRIGHT: (C)2008,JPO&INPIT
