In an autonomous driving system in which a plurality of autonomous driving vehicles drive under the control by occlusion control, such a situation is prevented that a vehicle is disabled to drive by a failure of an external world sensor for recognizing an obstacle and stops in an occlusion region thereby to obstruct advancement of overall succeeding vehicles to remarkably degrade the efficiency of the overall transportation work. In the autonomous driving system of the present invention, an autonomous driving vehicle which detects an obstacle or a driving road by a sensor and performs autonomous driving includes sensor state evaluation means configured to evaluate a state of performance degradation of the sensor, speed and steering angle control value setting means configured to provide limit values to the driving speed and the steering angle based on a state of performance degradation of the sensor, and movement obstacle evaluation means configured to evaluate an influence on movement of other vehicles when the vehicle stops at a position at present. When the sensor suffers from performance degradation, the vehicle stops after it drives within the set limit values to the speed and the steering angle to a point at which the vehicle does not obstruct movement of other vehicles.

Even in a case where a hash algorithm (hereinafter, referred to as A) that is used in the authentication system is changed, employing such a configuration enables the system to be successively utilized.

A motor control apparatus for a hybrid vehicle in which a diesel engine is used is disclosed by which the compulsory regeneration time period of the hybrid vehicle is reduced to achieve enhancement of the fuel cost. The motor control apparatus for a hybrid vehicle includes a filter for collecting particulate matter in exhaust gas of the diesel engine, compulsory regeneration means for compulsorily regenerating the filter, and battery charging means for converting the output power of the diesel engine into electric power based on a charged state of the battery and charging the battery with the electric power. When the compulsory regeneration is executed, the supply of electric power to the battery by the engine is inhibited.

For an error rate QBER, threshold values are preset, including a threshold value Q_bit for frame synchronization processing, a threshold value Q_phase for phase correction processing, and a threshold value Q_Eve for eavesdropping detection. Upon the distribution of a quantum key from a sender to a receiver, when the measurement value of QBER is deteriorated more than Q_bit, frame synchronization processing is performed. When the measurement value of QBER is deteriorated more than Q_phase, phase correction processing and frame synchronization processing are performed. When QBER does not become better than Q_Eve even after these recovery-processing steps are repeated N times, it is determined that there is a possibility of eavesdropping, and the processing is stopped.

The drive mode of a hybrid drive is controlled by: detecting a drive mode change signal characterizing a planned drive mode change, and determining a torque shortfall, which would occur due to the drive mode change. Furthermore, the method provides for comparing the torque shortfall with a threshold value, and blocking a drive mode change, if the comparison step reveals that the torque shortfall is above the threshold value. Otherwise, the method provides for: automatically performing a drive mode change according to the drive mode change signal, if the comparison step reveals that the torque shortfall is not above the threshold value.

In a refrigeration unit including a variable performance compressor driven by an inverter motor, a sensor is configured to detect a physical amount corresponding to a refrigerant pressure on the high-pressure side of a refrigerant circuit. A measured value of the physical amount is compared with a first reference value corresponding to a first predetermined pressure of the refrigerant and a second reference value corresponding to a second predetermined pressure lower than the first predetermined pressure. A protective operation can start if the comparison result indicates that an actual refrigerant pressure is higher than the first predetermined pressure. The performance of the compressor can be gradually lowered if the comparison result indicates that an actual refrigerant pressure is between the first predetermined pressure and the second predetermined pressure.

It is possible to reliably avoid a problem that radiation irradiation does not stop even when an accumulated radiation dose reaches a target radiation dose. An AEC unit starts monitoring an integrated value of a radiation dose detection signal from a detection pixel and an output of an irradiation continuation signal at the same time, and continuously transmits the irradiation continuation signal in a predetermined period while the integrated value does not reach a threshold value. When the integrated value reaches the threshold value, the output of the irradiation continuation signal is stopped. The irradiation continuation signal is transmitted to an irradiation signal I/F of a radiation source control device through an irradiation signal I/F by wireless. The radiation source control device stops X-ray irradiation by an X-ray source when the irradiation signal I/F does not receive the irradiation continuation signal.

A method of operating a controller of an industrial machine capable of reducing a rise in temperature of a processor, easily restoring and resuming the operation even if the operation is stopped by the rise in temperature, and further possibly preventing the stop of the operation of the controller by the rise in temperature. When temperature in the controller is lower than a set value, the processor performs a plurality of processings in each predetermined period to do normal operation. When the temperature rises to a set value or higher, processing related to the controlling axes is stopped, a motor is stopped, and the processor performs only minimum or limited required processing, i.e., processing related to a man/machine interface such as processing related to a programmable controller and processing for display and operates in a low-electric-power consumption mode except the period when the processor performs the minimum or limited required processing. In addition, as the temperature rises, the operating speed of a machine controlled by the controller is reduced to reduce heat generation and the rise in temperature of the processor.

An electricity storage device (41) stores energy produced in regenerative operation of a cage (14) and supplies the stored energy to a drive system of the cage (14) in powered operation. A control device for hybrid drive-type elevator monitors energy capacity of the electricity storage device (41), and when the energy capacity is below a predetermined capacity, the control device changes the direction of travel of the cage (14) from a powered direction to a regeneration direction and stops the cage at the nearest floor. This prevents the cage (14) from stopping between floors due to the lack of energy to secure the safety of passengers.

A vehicle air-conditioner control system according to the present invention activates an air conditioner in response to a command from an air-conditioner remote controller before a passenger is onboard, controls the air conditioner based on a heat load detected by a heat load detector, controls the air conditioner to be set in a silent mode so as not to make the passenger feel uncomfortable due to an air-conditioning wind when a passenger-proximity determiner determines that the passenger is proximate to the vehicle.

A vehicle 10 according to the embodiment of the present invention is applied to a charge-discharge system CDS. The charge-discharge system includes the vehicle 10, an electric power cable 20, a plug-in station 30, a HEMS 40, and a commercial power supply 50. From the HEMS 40 to the vehicle 10, a request for charge to charge an electric storage device 11 and a request for discharge to allow an external electric load to use an electric power of the electric storage device 11 are transmitted. When a request is changed from the request for charge to the request for discharge, or vice versa, the vehicle 10 realizes a charge-discharge stop state in which neither a charging operation nor a discharging operation is performed without directly changing from the charging operation to the discharging operation, or vice versa.
