Abstract

A power supply system includes: a power transmission circuit provided on the ground side; a high frequency generation circuit that supplies high-frequency electric power to the power transmission circuit; a measurement unit that measures a physical quantity corresponding to the degree of coupling between the power transmission circuit and a power reception circuit provided in a vehicle; and a control unit. When the degree of coupling is determined, based on the measured physical quantity, to be lower than a predetermined degree, the control unit sets the impedance of the power transmission circuit to a first impedance and thereby sets the power transmission circuit to a non-resonant state. In contrast, when the degree of coupling is determined to be not lower than the predetermined degree, the control unit sets the impedance of the power transmission circuit to a second impedance and thereby sets the power transmission circuit to a resonant state.

Abstract

This motor control device (351-354) comprises a torque command calculation unit (40) that calculates a torque command value (Trq*), an electric current command calculation unit (50) that calculates an electric current command value (I*), an electric power converter (55), and a stopping position adjuster (67). Except for a case in which a prescribed exemption requirement is met, the stopping position adjuster (67) executes, at a time of locked energizing when a multi-phase motor (60) is energized in a state in which rotation of the multi-phase motor (60) has stopped, a "stopping position adjustment process" for adjusting a rotational stopping position within a prescribed position adjustment range. In the stopping position adjustment process, the stopping position adjuster (67) adjusts the rotational stopping position so as to reduce the electric current absolute value of a maximum electric current phase, in which the electric current absolute value is at maximum, from among the phases. The torque command calculation unit (40) or the electric current command calculation unit (50) calculates a torque command value (Trq*) or an electric current command value (I*) in which the rotational stopping position after adjustment is reflected.

Abstract

In the present invention, an MG-ECU functions as a motor control device that controls a motor generator connected to an engine. Using a revolution speed detection value obtained by detecting the revolution speed of the motor generator, the MG-ECU performs feedback control so as to bring the revolution speed close to a command value, thereby causing the motor generator to output a damping torque in a phase reverse to that of torque variation in the engine. The MG-ECU switches the control gain of the feedback control between a plurality of levels including a low gain and a high gain. Furthermore, regarding a first transition (UT), in which transition is made from the low gain to the high gain, and a second transition (DT), in which a transition is made from the high gain to the low gain, a non-linear gain transition is implemented at least during the second transition (DT).

Abstract

An electrical charging apparatus working to electrically charge an electrical storage device includes an electrical power converter and a controller. The electrical power converter converts an alternating-current input voltage into a direct-current voltage and outputs it to the electrical storage device. The controller works to control the electrical power converter to pulsate the charging current supplied from the electrical power converter to the electrical storage device. The controller also controls the electrical power converter to set a pulsation frequency of the charging current to an integral multiple of the frequency of the input voltage and also to bring a phase difference between a zero-crossing time of the input voltage and a time when the charging current is minimized to be smaller than or equal to one-eighth of one cycle of the input voltage.

Abstract

According to the present invention, an MG-ECU functions as a motor control device for controlling a motor generator connected to an engine. The MG-ECU uses a rotational speed detected value obtained by detecting a rotational speed of the motor generator to perform feedback control such that the rotational speed approaches a command value (NC). When the rotational speed of the engine rises, if an average value, over a predetermined time, of an engine torque (TE) output from the engine exceeds a threshold, the MG-ECU, in response, outputs a rise command causing the motor generator command value (NC) to rise.

Abstract

Power is supplied by use of resonance from a power transmission device (50) to the side of a power reception coil (31) that is magnetically coupled to a power transmission coil (51). In this case, in order that overcurrent does not flow through a resonant circuit (53) even if the resonant circuit is brought into an operation state in a state in which the power transmission coil and the power reception coil are not magnetically coupled to each other, the power transmission device supplies AC power from a main power supply device (70) to the resonant circuit including the power transmission coil that is magnetically coupled to the power reception coil provided in a power reception device (30) via power lines (NL1, NL2) and brings the resonant circuit into a resonant state when the power reception coil is close to the power transmission coil and into a non-resonant state when the power reception coil is not close to the power transmission coil. Furthermore, when detecting an abnormality associated with the supply of power to the power reception device, the power lines are switched to a non-conduction state and the supply of AC power from the main power supply device to the resonant circuit is interrupted.

Abstract

A torque command calculation unit (40) of a braking force control unit (400) calculates a torque command value (Trq*) for a motor (60) on the basis of required braking force commanded from the outside. The relationship between the torque of the motor (60) and braking force generated in electric brakes (81-84) has hysteresis characteristics. When the torque increases, the braking force increases along a positive efficiency line, and when the torque decreases, the braking force decreases along an inverse efficiency line. A specific controller (48) of the torque command calculation unit calculates the torque command value (Trq*) so that the actual load is caused to approach a load command value or the actual position is caused to approach a position command value. A control adjuster (471, 472, 473) adjusts parameters of the specific controller (48), or of control calculation at the input side or output side of the specific controller (48), during an increasing operation, a decreasing operation, or a transition between the increasing operation and the decreasing operation.
