    摘要： The invention provides an electric power converter system which uses a standard low-priced control processor and is suitable for improving the voltage utilization factor in the output voltage. D-axis and q-axis voltage commands and a rotation angle .theta. defining a voltage command vector on a rotating coordinate system are input to a voltage calculation circuit. The voltage command vector is transformed in a rotating coordinate transformation unit into a .alpha. axis and .beta. axis voltage commands to be defined relative to stationary coordinate system. A judgment unit determines which section contains the voltage command vector, from among three sections on the stationary coordinate system having one axis thereof (.alpha.-axis for example) coinciding with one axis of the three phases. A three phase voltage generation unit then selects a method of calculation on the basis of a result of the section determination, and calculates three phase voltage command values respectively utilizing the .alpha. axis and .beta. axis voltage command values. Since calculation requires only a simple add/subtract and shift operation, a high performance economical power converter system which improves the voltage utilization factor substantially can be realized.

    摘要： The invention provides a control apparatus for an induction motor to maintain torque following controllability even with use of inexpensive speed detection units having detection delay. In a control unit, a phase correction arithmetic circuit uses a motor speed detection value detected by a speed sensor and a low-pass filter and a detection delay time of a control system to compute a correction phase. An adder adds the correction phase to a magnetic flux phase obtained by a vector control computation. The addition corrects a magnetic flux phase deviation due to detection delay of the correction phase of a primary current command, and compensates for the detection delay so as to maintain the torque following controllability of an inductor motor.

    摘要： An object of the present invention is to secure safe driving of electric vehicles by enabling torque control regardless of sensor disorder. In the present invention, the mode of current sensor disorder is detected by a sensor disorder detection means. If it is found as a result that only 1 out of 3 current sensors is failing, the current of the failing current sensor is estimated by 2 normal current sensors and the torque control of the motor is continued by the ordinary torque control system. If 2 or more current sensors are found to be failing, a torque control system based on an AC current reference operation means is formed to control the motor torque based on the AC current reference. If a sensor failure detection means determines that only 1 phase is failing in the speed sensor, the motor torque is controlled by using the remaining 1 phase to detect the rotating angular speed of the motor. If all speed sensors are failing but the current sensors are normal, the motor torque is controlled by estimating the motor torque from the 3 phase AC current. If both the current sensors and the speed sensors are found to be failing, the motor torque is controlled based on the estimated torque control and rotating angular speed to continue the driving that is needed to avoid dangerous situations.

    摘要翻译： 本发明的目的是通过实现扭矩控制来确保电动车辆的安全驾驶，而不管传感器无序。 在本发明中，由传感器无序检测装置检测电流传感器障碍的模式。 如果发现3个电流传感器中只有1个发生故障，则故障电流传感器的电流由2个正常电流传感器估计，电机的转矩控制由普通转矩控制系统继续。 如果发现2个以上的电流传感器发生故障，则形成基于交流电流基准运算装置的转矩控制系统，以基于交流电流基准来控制电动机转矩。 如果传感器故障检测装置确定速度传感器中只有1相故障，则通过使用剩余的1相来检测电动机的旋转角速度来控制电动机转矩。 如果所有速度传感器故障，但电流传感器正常，则通过从三相交流电流估计电机转矩来控制电机转矩。 如果发现电流传感器和速度传感器都有故障，则基于估计的转矩控制和旋转角速度来控制电动机转矩，以继续驾驶以避免危险情况。

    摘要： A control apparatus of a motor drive vehicle includes a unit for generating a target vehicle speed; a speed instruction unit for generating a target motor rotational speed of the motor based upon a preset motor control pattern in response to the target vehicle speed; a power circuit for operating the motor at the target motor rotational speed upon receipt of the target motor rotational speed; a variable transmission unit for converting a drive output from the motor into a transmission ratio for instructing a rotational speed of the drive output, and transferring the converted transmission ratio to a drive shaft of the motor drive vehicle; and a transmission ratio calculating unit for determining the transmission gear ratio based on the target vehicle speed and the target motor rotational speed thereby to instruct the determined transmission gear ratio to the variable transmission unit. A control method sets a target vehicle speed value; produces a target motor rotational speed based upon the target vehicle speed value and a preset motor control pattern; operates the motor at the target motor rotational speed; determines a transmission gear ratio based upon both of the target vehicle speed and the target motor rotational speed; and converts a rotational speed of a drive output into the transmission ratio and transfers the converted transmission ratio to a drive shaft.
