摘要： PROBLEM TO BE SOLVED: To enhance the voltage stabilization effect of a power line in a system which generates system voltage in the power line by boosting the voltage of a DC power supply with a boost converter and drives an AC motor by the system voltage through an inverter. SOLUTION: A motor controller 37 executes system voltage stabilization control for controlling an input voltage of an MG unit 30 so as to suppress fluctuations in system voltages. In that case, the torque control of an AC motor 14 and the input power control of the MG unit 30 are independently controlled to stabilize the torque control and the input power control. Between immediately after system startup and before the precharge completion of a smoothing capacitor 24, conversion voltage control is executed to control the output voltage of the boost converter 21. During execution of the conversion voltage control, the system voltage stabilization control is prohibited. After the precharge completion of the smoothing capacitor 24, the conversion voltage control is switched to the conversion power control for controlling the output power of the boost converter 21.

摘要： PROBLEM TO BE SOLVED: To prevent generation of noise while preventing overheat of an inverter when an AC motor is locked. SOLUTION: When an AC motor is locked, vector switching control is performed to vary the current vector of the AC motor such that loss of an inverter is reduced by increasing loss of the AC motor thus avoiding concentration of current on a specific switching element of the inverter. In the vector switching control, torque of the AC motor is held constant by switching a command current vector in the order of current vectors i0, i1 and i2 thereby increasing reactive power of the AC motor periodically. The current vector i0 generates a torque slightly smaller than the maximum torque, and the current vectors i1 and i2 generate a torque identical to that of the current vector i0 and increase reactive power as compared with the current vector i0.

摘要： PROBLEM TO BE SOLVED: To improve the voltage stabilization effects of a power supply line in a system for driving an AC motor via an inverter with a system voltage, by allowing the power supply line to generate the system voltage, while stepping up a voltage of a DC power supply using a step-up converter. SOLUTION: Second system-voltage stabilization control for suppressing variations in system voltage is executed by controlling the step-up converter 21, while executing first system-voltage stabilization control for suppressing the variations in system voltage by operating input power of the AC motor 14. the frequency band for suppressing the variations in system voltage by the first system-voltage stabilization control is separated from a frequency band for suppressing the variations in system voltage by the second system-voltage stabilization control. Consequently, while preventing interference between the first/second system-voltage stabilization control, the system voltage can be stabilized effectively by using both of the first/second system-voltage stabilization control.

摘要： PROBLEM TO BE SOLVED: To detect the existence of abnormality of a smoothing capacitor which smoothes the system voltage of a system that generates system voltage in a power line by boosting the voltage of a DC power source with a step-up converter and drives an AC motor via an inverter by this system voltage. SOLUTION: This controller executes the system voltage stabilization control to suppress the ripple of system voltage by operating the input voltage of an MG unit 30 (AC motor 14), so that the deviation ΔVs between the target value Vs * and the detected value Vsf of the system voltage may be smaller. Moreover, fixing eyes upon that when a system voltage smoothing function drops due to drop of the capacity of the smoothing capacitor 24, the ripple in the high frequency zone of the system voltage becomes large and the input power manipulation variable Pm of the MG unit 30 by the system voltage stabilization control oscillates in high frequency so as to compensate it, this controller judges the existence of abnormality (capacity drop) of the smoothing capacitor 24, based on the frequency and the amplitude of the input power manipulation variable Pm in system voltage stabilization control.

摘要： PROBLEM TO BE SOLVED: To improve voltage stabilization effect of a power line of a system generating system voltage in the power line, by boosting voltage of a DC power source with a boosting converter and driving an AC motor through an inverter by system voltage. SOLUTION: Input power of the AC motor 14 is operated so that a difference ΔVs becomes small between a target value Vs* and a detection value Vsf of system voltage, and system voltage stabilization control is performed for suppressing fluctuation of system voltage. Conversion power control for controlling conversion power is performed so that a difference ΔPi becomes small between a command value Pif* and a detection value Pi of conversion power (output power of boosting converter 21). A conversion power correction amount Px is operated from an input power operation amount Pm of system voltage stabilization control, and conversion power is corrected by reflecting the conversion power correction amount Px on conversion power control. Thus, dispersion (dispersion of system voltage) is corrected in conversion power due to a control error of conversion power control. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To secure the amount of charge for a high-voltage battery without adversely affecting driving performance, while enhancing the mountability of a vehicle's power source and auxiliary devices and the efficiency of recycling deceleration energy. SOLUTION: An engine 14 driving front wheels 11, 12 is provided on the front side of the vehicle 10. A motor generator 24 for driving rear wheels 18, 19 and a compressor 25 for an air conditioner are provided on the rear side of the vehicle 10. The rear wheels 18, 19, the motor generator 24 and the compressor 25 are connected to one another via a power distribution device 23. If an alternator 17 cannot generate electric power regardless of a request to charge the high-voltage battery 33, the amount of electric power that the motor generator 24 generates is increased so that the high-voltage battery 33 is charged with the electric power generated by the motor generator 24. Main driveshaft torque (driving torque for the front wheels 11, 12) is determined so that a decrease in auxiliary driveshaft torque (driving torque for the rear wheels 18, 19) caused by the increase in the amount of electric power that the motor generator 24 generates is canceled out by an increase in the main driveshaft torque.

摘要： PROBLEM TO BE SOLVED: To effectively improve fuel economy when traveling by dividing the power of an engine into a drive shaft side and a first MG (motor generator) side with a planetary gear mechanism.
SOLUTION: The power of an engine 10 is divided into a sun gear shaft 18 and a ring gear shaft 19 with a first planetary gear mechanism 14. Furthermore, the power of the sun gear shaft 18 is divided into a sun gear shaft 24 and a ring gear shaft 25 with a second planetary gear mechanism 20, and the ratio of power transmitted from the engine 10 to the first MG 11 side is made small by transmitting the power of the sun gear shaft 24 to the first MG 11. On the other hand, both powers of the ring gear shaft 19 of the first planetary gear mechanism 14 and the ring gear shaft 25 of the second planetary gear mechanism 20 are transmitted to a drive shaft 26, and thereby the ratio of power transmitted from the engine 10 to the drive shaft 26 side is made large. Thus, the electric loss of the MG 11, 12 and inverters 31, 32 is reduced, and the energy loss of the whole vehicle is reduced.
