摘要： A method and apparatus for driving an electric vehicle having a synchronous traction motor. A peak value of induced electromotive force of the synchronous motor at a maximum allowable rotating speed is set to a value which is lower than an allowable voltage of the smoothing capacitor of the inverter and lower than a maximum allowable voltage of the power switching elements composing the inverter. The synchronous motor is thus constructed so that a peak value V0max of the maximum induced electromotive force at the maximum allowable rotating speed N2 of the synchronous motor satisfies a relation of V0max≦VCmax where VCmax is an allowable voltage of the smoothing capacitor.

摘要： An electric vehicle control system which maintains good driving performance under normal conditions, and can cut off driving current upon malfunction of a microcomputer before restarting. A setting circuit of a comparing and operating circuit has a set signal fixed to V2 if an accelerator pedal is released. If a microcomputer malfunctions to drive an inverter absent a depression of the accelerator pedal, a current flows from a battery and a battery current sensor generates an output signal n. If this value exceeds V2, a comparator is turned on, which also turns on a transistor to energize a relay and disconnects an inverter drive signal s to break the power supply from an inverter to the ac motor. Upon disconnection, an alarm lamp is lit to issue an alarm to the driver. The disconnection is held by a delay circuit until the power is reset.

摘要： An apparatus for steadily and efficiently controlling a synchronous motor is equipped with a function for generating dq-axis current commands so that the terminal voltage of the synchronous motor may not exceed the voltage which a power converter can output even at a current transition time, a current control function for correcting a fluctuation of a D.C. input voltage, and a function for eliminating the D.C. input power to zero when performing field weakening control. The dq-axis current command generator is so built as to retrieve current command tables listing high-efficiency data in advance by torque commands and rotational speeds of the synchronous motor. There are a plurality of current command tables converting maximum terminal voltages of the synchronous motor. A means is provided to select an optimum one of said current command tables according to the D.C. input voltage. In this case, a value obtained by subtracting a preset value from the D.C. input voltage is used for this selection of an optimum current command table.

摘要： The present invention provides a protection apparatus in a control system for an electric vehicle which is capable of performing back-up driving by using a back-up control method, without using output from sensors even if the sensor in the control system for ordinary driving is failed. When at least one of the current sensor, the speed sensor and the accelerator sensor is detected to be abnormal, a back-up control voltage v1 is output as an abnormal signal from a running back-up control circuit. As a result, the running back-up control circuit sets the limiter of the output of the current control circuit to zero and switches the control signal to the inverter from vector control to V/f voltage control.

摘要： In an electric vehicle drive controller, a drive controller has a controlling means which incorporates means for calculating a magnetic flux command from a basic torque command, for calculating a torque current command, exciting current command and slip frequency, and for operating vector calculation, and drives the motor. Voltage or power density of the power source is input to a correction coefficient calculating means and then input to a magnetic flux generating means by a correction coefficient to correct a magnetic flux. A magnetic flux generating means calculates the magnetic flux command by limiting and correcting the magnetic flux command according to the basic torque command and rotating speed, and determines a control variable for the magnetic flux command in correspondence to the motor rotating speed and torque command. By controlling the voltage to be applied to the motor in correspondence to the quantity of state of power source, it is possible to operate a drive unit on the most efficient point and reduce the size of electric power converter.
