摘要： A synchronous motor control system which can freely regulate n-phase electric currents in a synchronous motor to control the characteristics of the synchronous motor. The synchronous motor control system can enhance the output torque per unit weight of a synchronous motor (40) simultaneously with reducing torque ripples. The waveform of three phase alternating currents is freely corrected over a range of +30 degrees from a specified electrical angle, at which a target phase current drawing a sine-wave curve reaches its peak value. It is assumed that this range of .+-.30 degrees corresponds to a range of 0 degree to 60 degrees. By way of example, the waveform is controlled to the peak value of the phase current in a range of 0 degree to 28 degrees. The correction of the phase current is carried out for the target phase which produces the primary magnetic flux of a revolving magnetic field. This improves a fall in torque due to the phase shift and reduces torque ripples while keeping the mean torque at a high level. The system of the invention can arbitrarily regulate the torque waveform of the synchronous motor (40), thereby freely controlling the torque characteristics of the synchronous motor (40).

摘要： The prior art technique should return the voltage applied to a synchronous motor to zero in the process of measurement of an electrical angle. This causes foreign noises. The structure of the present invention utilizes the fact that the electrical angle of a three-phase synchronous motor 40 depends upon the inter-coil inductances. The procedure of the present invention applies a predetermined voltage for measurement to each combination of coils, and measures variations in electric currents flowing through the respective coils. The electric current flowing through each coil is attenuated in the presence of a driving current in the three-phase synchronous motor 40, compared with the case in the absence of a driving current. The procedure of the present invention accordingly refers to a table 122A to correct the observed values of electric currents based on the variations in electric currents, and refers to another table 122B to read the electrical angle .pi. corresponding to the corrected values of electric currents. The structure of the present invention can determine the electrical angle without returning the driving current to zero, thereby shortening the time period required for determination of the electrical angle while preventing the occurrence of foreign noises.

摘要： An electrical angle detecting device for detecting the electrical angle of a synchronous motor utilizes differences in inductance between phases with the angle of a rotor 50 to determine electrical angle. Voltage is applied across predetermined phases, the currents Iu, Iv, Iw flowing through U, V, W phases as a function of the differing inductance with angle of the rotor 50 are simultaneously detected, and the electrical angle is determined from relationships among the three currents stored in memory beforehand. In a first stage, the electrical angle is determined in the 0-.pi. range or the .pi.-2.pi. range by an approximation calculation and in a second stage the asymmetry of the maximum currents produced by the voltage applied across the phases is utilized to ascertain the range in which the electrical angle falls. the electrical angle can thus be unambiguously ascertained to enable sensorless detection of rotor position (electrical angle) even when the rotor is at rest or is rotating slowly.

摘要： A power output apparatus of the invention includes a clutch motor (30) and an assist motor (40) that allow energy output from an engine (50) driven at a driving point of high efficiency to be converted to energy expressed as the product of a revolving speed and a torque of a drive shaft (22) and to be output to the drive shaft (22). In case that a large torque is required, for example, when the vehicle starts on a rising slope or runs at a low speed, the engine (50) is driven at a high-energy driving point having a large torque and a high efficiency. This structure causes large electric power to be generated by excess energy greater than the energy generally consumed and enables a battery (94) to be charged with the large electric power. The power output apparatus of the invention further has functions of predicting the process of charging the battery (94) with the large electric power based on a driving state of the vehicle and topographical information and lowering the remaining charge of the battery (94) in advance according to the requirements. This process effectively prevents the battery (94) from being damaged with excess charging.

摘要： A mean vehicle speed Va and a mean variation .DELTA.Va are factors reflecting a current driving condition and an expected driving condition of a vehicle, which relate to a charge-discharge amount of a battery. A target state SOC* of the battery is calculated from the mean vehicle speed Va and the mean variation .DELTA.Va. The charge-discharge amount of the battery increases with an increase in mean vehicle speed Va and mean variation .DELTA.Va. The lower charging state of the battery results in the higher charge-discharge efficiency. The structure of the present invention sets the target state SOC* of the battery and controls the actual state of the battery to the target state SOC*, thereby enhancing the charge-discharge efficiency of the battery and ensuring a sufficient supply of electric power required for driving the vehicle.

摘要： A power output apparatus (20) includes an engine (50), a clutch motor (30) connecting with a crankshaft (56), an assist motor (40) connecting with a drive shaft (22), and a controller (80) for controlling the clutch motor (30) and the assist motor (40). When an electrical angle of the rotors in the clutch motor (30) is equal to .pi./2, a constant current is made to flow through three-phase coils (36) of the clutch motor (30) in order to enable a torque equal to or greater than a maximum torque ripple of the engine (50) to be applied from the clutch motor (30) to a drive shaft (22) and the crankshaft (56). This locks up an outer rotor (32) and an inner rotor (34) of the clutch motor (30). This structure enables the torque and rotation of the engine (50) to be directly transmitted to the drive shaft (22) at a high efficiency.

摘要： A power output apparatus (20) of the present invention includes a clutch motor (30), an assist motor (40), and a controller (80) for controlling the clutch motor (30) and the assist motor (40). The clutch motor (30) includes an outer rotor (32) linked with a crankshaft (56) of a gasoline engine (50) and an inner rotor (34) connecting with a drive shaft (22). The assist motor (40) includes a rotor (42) connecting with the drive shaft (22). An electric current flowing through three-phase coils (36) in the clutch motor (30) enables the outer rotor (32) to be coupled with the inner rotor (34) with a certain slip. Electrical energy corresponding to the certain slip is recovered as an electric power via a first driving circuit (91). The assist motor (40) is controlled with the electric power via a second driving circuit (92) so as to apply a torque to the drive shaft (22). The power output apparatus (20) of the invention can transmit the power generated by the gasoline engine (50) to the drive shaft (22) at a high efficiency and produce a torque in the direction of rotation of the crankshaft (56).

摘要： The present invention provides a system for detecting a rotational orientation or electrical angle of a rotor without any specific sensor so as to efficiently control a synchronous motor even while the rotor is at a stop or rotates at a relatively low speed. An electrical angle of a rotor (50) is determined according to a previously stored relationship between inductances of different interphases and electrical angles. At a first step, an electrical angle .phi. is calculated either in a range of 0 through .pi. or in a range of .pi. through 2.pi. by approximation. At a second step, a range where the electrical angle .phi. belongs to is specified by taking advantage of asymmetrical property of a maximum current in response to a voltage applied to each interphase. An equivocal electrical angle .theta. is then determined in a range of 0 through 2.pi.. In order to control the driving current of a three-phase synchronous motor (40) at better efficiency, a preferable system of the invention determines the electrical angle according to the above method while the rotor (50) is under inactivating condition or rotates at a speed of less than a predetermined rotating speed, and detects the electrical angle with a reverse electromotive voltage while the rotor (50) rotates at a speed of not less than the predetermined rotating speed.
