Abstract: An information processing device acquires character strings in respective cells that are included in a first table and a second table in document data. When acquiring a character string, the device may identify the characters included in the character string by using a pre-trained model that has been trained in advance through machine learning. The device determines whether the second table corresponds to the first table based on similarities between character strings in cells that are included in the first table and character strings in cells that are included in the second table. When determining that the second table corresponds to the first table, the device identifies a difference between the character strings in the cells that are included in the first table and the character strings in the cells that are included in the second table and correspond to the cells included in the first table.

Abstract: A current command value calculating unit (174) calculates current command values for a rotor winding (30) and current command values for a stator winding (20) with respect to a torque command value between a first rotor (28) and a second rotor (18) and a torque command value between a stator (16) and the second rotor (18) based on an evaluation function representing a total copper loss of the rotor winding (30) and the stator winding (20) and using first and second magnetic interference models. The first magnetic interference model represents a relationship of a linkage magnetic flux Φin of the rotor winding (30) with respect to a current Iin in the rotor winding (30) and a current Iout in the stator winding (20). The second magnetic interference model represents a relationship of a linkage magnetic flux Φout of the stator winding (20) with respect to the current Iin, Iout.

Abstract: A noise generation cause identifying method and a noise generation cause identifying device are provided. A response correcting process corrects a sound signal obtained through a sound signal obtaining process based on obtained model information so that a frequency response of the obtained sound signal approaches a frequency response of a learning sound signal. A variable obtaining process obtains a variable output from a map by inputting the corrected sound signal to the map. A cause identifying process identifies a generation cause of a sound picked up by a microphone using the variable obtained through the variable obtaining process.

Abstract: A mapping, which is as a subject of learning, is a learning model that uses a sound signal as an input variable and outputs a variable indicating the cause of a sound in a vehicle. A learning method includes a signal correction process that corrects a sound signal by superimposing a noise signal on the sound signal, and an update process that updates the mapping through machine learning in which the sound signal corrected in the signal correction process serves as training data and a cause of a sound paired with the sound signal serves as teaching data.

Abstract: A vehicle control system to operate a vehicle autonomously with improved energy efficiency and ride quality is provided. A controller is configured to set a limit value of an operating point of an engine to reduce noises and vibrations. The operating point of the engine is restricted by the limit value within an acceptable region where an engine speed is higher than the limit value but an engine torque is lower than the limit value. The limit value is set to a first limit value when the vehicle is operated autonomously while carrying the passenger, and to a second limit value to expand the acceptable region when the vehicle is operated autonomously without carrying the passenger.

Abstract: When a drive shaft (37) is driven while the operation of an engine (36) is stopped, the rotation of an input-side rotor (28) is restricted by the engagement of a brake. Further, on the basis of the temperature Temp_SR of a brush (96) acquired by a temperature sensor (97), the distribution of torque Tcoup acting between the input-side rotor (28) and the first output-side rotor (18) and torque Tmg acting between the stator (16) and the second output-side rotor (19) is controlled. Consequently, drive performance when the drive shaft (37) is driven while the operation of the engine (36) is stopped is improved while local overheating of a slip ring (95) is prevented.

Abstract: A control system for a hybrid vehicle that can reduce a power loss resulting from shifting an operating mode from motor mode to hybrid mode is provided. A transmission that is adapted to distribute torque applied to an input element to a reaction element and an output element, and to change a ratio between a first torque delivered to the reaction element and a second torque delivered to the output element. A controller is configured to start an engine in a high mode in which a torque ratio of the output element to the input element is small if the vehicle speed is higher than a threshold value, and to start the engine in a low mode in which the torque ratio is greater if the vehicle speed is lower than the threshold value.

Abstract: An engine starting control system for hybrid vehicles is provided to prevent a temporal drop in drive force when starting an engine. The control system maintains an operating mode of a switching mechanism when starting the engine by the first motor, in a case that the vehicle is propelled in the forward direction by the first motor and that the switching mechanism is in a second mode, or in a case that the vehicle is propelled in the reverse direction by the first motor and that the switching mechanism is in the first mode. Thereafter, the control system increases a rotational speed of the engine to a self-sustaining speed, switches the operating mode of the switching mechanism, and increases torque of the engine.
