摘要： A motor control method controls a motor having windings of a plurality of phases and a cooling water channel. The motor control calculates an estimated maximum temperature of the winding of the phase that reaches a highest temperature from among the windings of the plurality of phases based on the input electrical power when the motor is in a lock state. The motor control further calculates an offset value based on a detected temperature of the windings and a detected temperature of the cooling water, and corrects the estimated maximum temperature based on the temperature of the windings and the offset value. The motor control further controls the input electrical power according to the estimated maximum temperature.

摘要： A control method and a control device for controlling a spark-ignition internal combustion engine that is equipped with a turbocharger and an exhaust gas recirculation device. The operation of the engine is carried out to perform a stoichiometric air-fuel ratio by performing exhaust gas recirculation even in a high-load range including a maximum-output operation point. When the maximum output operation point is required, intake air information such as atmospheric pressure and outside air temperature is used as a basis to calculate intake air density, which is compared with a predetermined density threshold. When the intake density is equal to or less than the density threshold at a high-altitude location or the like, an exhaust gas recirculation rate is set to 0. As a result, the maximum output can be higher than when exhaust gas recirculation is performed.

摘要： An abnormality determination device includes a control unit for determining an abnormality of a robot, the control unit being configured to calculate a measurement probability distribution which is a probability distribution using disturbance torque acquired during a predetermined period as a random variable. The control unit causes an average of the calculated measurement probability distribution to conform to an average of an evaluation normal model which is a predetermined probability distribution, compares the measurement probability distribution with the evaluation normal model of which the respective averages conform to each other, and determines an abnormality of the robot in accordance with a result of the comparison.

摘要： A hybrid vehicle includes two drive sources and two clutches, and is switchable between a neutral mode and a parallel mode during vehicle traveling. The two drive sources are both disconnected from drive wheels in the neutral mode, and are both connected to the drive wheels in the parallel mode. A control method for the hybrid vehicle includes implementing at least one of a first switching control and a second switching control. The first switching control includes, upon switching from the neutral mode to the parallel mode, implementing two synchronization controls on rotational speeds before and after the two clutches, concurrently during at least a partial period. The second switching control includes, upon switching from the parallel mode to the neutral mode, implementing two controls to cause transmitted torques of the two clutches to respectively approach zero, concurrently during at least a partial period.
