摘要： In a CT image of a living body, contours of internal organs thereof are discriminated. Parameters are beforehand stored in a memory for a plurality of internal organs of the living body. Applicators are attached onto the living body and then a high frequency power is applied to electrodes disposed therein so as to heat an internal portion of the body. Based on an intensity of an electric field generated in the body due to the applied power and the parameters stored in the memory, a temperature distribution on the CT image is estimated. To retain an estimated temperature of an objective tumor at a predetermined target temperature, the high frequency power and the cooling water in the applicators are controlled. In the estimation of the temperature distribution, the parameters of the living body are repeatedly corrected to minimize a discrepancy between a temperature measured at a preset position and an estimated temperature associated therewith.

摘要： An electric power steering device for a vehicle includes an estimation mechanism estimating if there is a possibility that a backward electric current flows in a booster circuit toward a vehicle battery device, and a boosting controller stopping the boosting operation of the booster circuit to prevent a backward electric current from flowing in the booster circuit when it is estimated that there is a possibility that a backward electric current flows by the estimation mechanism. The estimation mechanism estimates that there is a possibility that a backward electric current flows in the booster circuit when the steering condition of a steering wheel is a returning condition or a steering-held condition. Otherwise, the estimation mechanism estimates if a backward electric current flows on the basis of input and output voltages of the booster circuit and information on the switching of a first boosting switching element. Thereby, overheat of the booster circuit can be prevented.

摘要： In a power supply apparatus, a power supply circuit includes a primary power supply circuit including a high-voltage battery and a step-down circuit for stepping down the voltage of the high-voltage battery, and a secondary power supply circuit including a low-voltage battery and a step-up circuit for stepping up the voltage of the low-voltage battery. The primary power supply circuit and the secondary power supply circuit are connected in parallel. An output voltage of the secondary power supply circuit is set to be lower than an output voltage of the primary power supply circuit. When the output voltage of the primary power supply circuit becomes lower than a target voltage of the secondary power supply circuit, the voltage stepped-up by the step-up circuit is supplied to a motor drive circuit. Accordingly, power supply backup of an electric power steering apparatus can be performed at low cost.

摘要： The CPU calculates axial force matching external force that acts on a rack bar by combining steering torque MT that acts on a steering shaft with assist torque AT generated by an electric motor. The CPU then determines whether a vehicle is running straight based on a steering angle θ, a vehicle speed V, and the axial force F. Thus, even in a state where a control steering angle midpoint is deviated and a driver applies torque so as to return a turning position of a steering wheel to a neutral position, whether the vehicle is running straight can be accurately determined by making a determination by using the axial force F that acts on the rack bar. The CPU can set a considerably accurate control steering angle midpoint by calculating a smoothed steering angle midpoint by using an instantaneous steering angle midpoint in an accurately determined straight-running state.

摘要： When it is determined that the torque output from the electric motor abnormally fluctuates or the torque output from the electric motor varies between clockwise and counterclockwise turning operations of the driver's steering wheel, the steering assist control is continued if the vehicle speed v is equal to or lower than the reference speed v0. In this case, the width of the dead band of the steering torque in the assist map used to calculate the target assist torque is increased. Thus, only in a case where the vehicle is moving at a low speed and the driver's steering wheel is operated with a great force, the steering assist torque is produced to alleviate the burden on the driver. In the other cases, the electric motor is stopped to minimize a sense of discomfort in the steering operation.

摘要： A battery condition diagnosis apparatus for a vehicle gradually supplies electricity to an electric motor of an electric power steering apparatus when a predetermined time elapses after an ignition switch is turned off. The apparatus diagnoses the deteriorated condition of the battery on the basis of the amount of supplied electricity and the detected battery voltage which changes in accordance therewith. The electric motor may be a brushless DC motor. In this case, current is supplied to the electric motor such that only d-axis armature current Id in the d-q coordinate system flows, to thereby prevent the electric motor from rotating, whereby safety is secured. Accordingly, the condition of the battery can be accurately diagnosed by supplying electricity to the electric motor without changing the condition of the vehicle.

摘要： When it is determined that a malfunction has occurred in a rotational angle sensor, an electronic control unit changes the control manner from the normal assist control to the sensorless assist control. In the sensorless assist control, an assist stop command unit receives the information concerning the motor rotational angular speed ωm from an angular speed conversion unit. Then, the motor rotational angular speed ωm is compared with the threshold value ωm1. If the motor rotational angular speed ωm is equal to or higher than the threshold value ωm1, an assist enabling signal is transmitted to a PWM voltage production unit to continue the power assist. On the other hand, if the motor rotational angular speed ωm is lower than the threshold value ωm1, a stop command signal is transmitted to the PWM voltage production unit to stop the power assist.
