Abstract: A power source system includes: a rotary electrical machine; a power source; a switch that is provided between the power source and the rotary electrical machine; and a power source control device that controls opening/closing of the switch in response to a request for power feeding to the rotary electrical machine. The power source control device is configured to, in response to the power source system stopping operation, bring the switch into a closed state in a predetermined period of time. A rotary electrical machine control device controlling the rotary electrical machine includes: a determination unit that, in response to the power source system stopping operation, determines that the switch is in the closed state; and an abnormality diagnosis unit that, in response to the determination unit determining that the switch is in the closed state, performs an abnormality diagnosis of the rotary electrical machine.

Abstract: An apparatus for controlling a motor having a housing in which a stator and a rotor are disposed. The motor is cooled by a cooling oil in the housing. The apparatus includes a control unit configured to control the motor. The control unit has a temperature increase mode for heating the cooling oil with use of heat generated by a resistance of a coil provided in the stator.

Abstract: A first and a second control device capable of transmitting and receiving signals to and from a third control device that performs an overall management to the control devices. The third device transmits a command signal to the second device in response to a reception signal from the first device. The first device transmits, to the second device and the third device, an electrical power storage unit signal includes at least one of control information and abnormality information about charging/discharging. The second device includes a function of controlling actuation of a rotating electrical machine on the basis of an actuation command signal about actuation of the rotating electrical machine transmitted from the third device in response to the electrical power storage unit signal, and a function of controlling actuation of the rotating electrical machine on the basis of the electrical power storage unit signal transmitted from the first device.

Abstract: A motor control device includes coil temperature detection means, cooling oil temperature detection means, and a control unit. The control unit implements a coil protection torque restriction and a cooling oil protection torque restriction. The control unit makes it easier for the coil protection torque restriction to be preferentially implemented in a low rotation operating region in which a motor operates at a low rotation speed equal to or lower than a predetermined value, and makes it easier for the cooling oil protection torque restriction to be preferentially implemented in a high rotation operating region in which the motor operates at a higher rotation speed than in the low rotation operating region.
