    Abstract: A method is provided for an HEP system that includes a gas turbine engine and an electric motor configured to assist the gas turbine engine by rotating a first shaft of the gas turbine engine. The method includes receiving a throttle command, and determining, based on an amount of electric power available to the electric motor, a power allocation between the gas turbine engine and the electric motor for an acceleration period during which a rotational speed of the first shaft is accelerated to implement the throttle command. The method also includes determining a target clearance between a tip of a rotor blade and a case structure for the acceleration period and, during the acceleration period, implementing the power allocation and operating an active clearance control (ACC) system to establish the target clearance. A system for an aircraft and a method for a HEP system are also disclosed.

    Abstract: A transmission controller includes a processor configured to set acceleration/deceleration start timing at which a vehicle starts accelerating or decelerating, based on at least one of a sensor signal representing the situation around the vehicle, the current position of the vehicle, a map including information on a road being traveled by the vehicle, and operation of the vehicle by a driver, downshift a second transmission of a power train including two motors and an engine before the acceleration/deceleration start timing, and control the power train to vary first and second gear ratios of a first transmission so as to keep the RPM of the engine constant. The first transmission is capable of steplessly varying the first and second gear ratios, which are gear ratios between one of the motors and the engine and between the other motor and the engine, respectively.

    Abstract: A control target for a control device (10) is a vehicle drive device (1) including a rotating electrical machine (MG), and the control device (10) includes: an actual rotational speed obtaining part (14) that obtains an actual rotational speed (Nm) which is an actual rotational speed of the rotating electrical machine (MG); an actual torque obtaining part (15) that obtains actual torque (Tm) which is actual torque of the rotating electrical machine (MG); and a determining part (16) that determines a state of the rotating electrical machine (MG). The determining part (16) determines that the state of the rotating electrical machine (MG) is a negative torque abnormality, when the actual torque (Tm) has a negative value smaller than a torque threshold value (THt) set based on a relationship between the actual rotational speed (Nm) and target torque (Tmt) of the rotating electrical machine (MG).
