Abstract: A power conversion device includes a semiconductor module, a cooling device, a case, which accommodates the semiconductor module and the cooling device, a connector, which is connected to an inlet pipe, which is a refrigerant flow pipe of the cooling device, and a sealing member, which seals between the inlet pipe and the connector. The connector includes a pipe portion, which communicates with the inlet pipe, and a flange portion, which is secured to the case. The pipe portion and the flange portion are joined to each other with the pipe portion located in an insertion hole of the flange portion.

Abstract: In a motor control device for a steer-by-wire steering device, the motor control device having a redundant system consisting of two systems, a first turning current command value is calculated in a first system, and a second turning current command value is calculated in a second system. A third processor outputs the first turning current command value when the two current command values are not divergent and outputs the second turning current command value when the two current command values are divergent. When a determination of a rapid steering operation is made, the third processor outputs the first turning current command value regardless of whether or not the two current command values are divergent.

Abstract: Each control circuit of a control device for a vehicle drives a motor in one of driving modes that are switched according to an operation state of the control circuit of a system other than an own system. The driving modes include an own-system shutdown mode in which the power supply to a winding set of the own system is stopped when the operation state of the control circuit of a system other than the own system is abnormal. Even when the operation state of the control circuit of a system other than the own system is abnormal, each control circuit does not shift the driving mode to the own-system shutdown mode when an own operation state is a specific operation state in which safety problems are deemed unlikely.

Abstract: A control device includes control circuits of a plurality of systems. When a transition condition is established, the control circuits of the systems make transition of a driving mode from a first driving mode to a second driving mode, and when a return condition is established in a state in which the driving mode has transitioned to the second driving mode, the control circuits of the systems make transition of the driving mode from the second driving mode to the first driving mode while gradually changing the current command values of the control circuits' own systems toward the current command values before the adjustment.

Abstract: Control calculation units of a back system in each actuator operate by a collaborative drive mode in which a torque is output to a motor drive unit by using an information transmitted and received mutually by a communication between the systems in common. Cooperative control calculation units in a reaction force actuator and a turning actuator can operate in cooperation with each other based on the information transmitted and received mutually by a communication between actuators. A communication between adjacent systems and a communication between adjacent actuators are restored, when a focus control calculation unit is restored, after the focus control calculation unit is stopped during operation and at least one of the communication between adjacent systems or the communication between adjacent actuators is interrupted.

Abstract: A first actuator and a second actuator each have a plurality of control calculation units provided redundantly and a plurality of motor drive units provided redundantly. In the first and the second actuators, the control calculation units of the systems paired with each other transmit and receive information to and from each other by a communication between the actuators. When a failure occurs in any system in either of the two actuators, or when a failure occurs in a communication between actuators in either system, the control calculation unit of each actuator of the system in which the failure occurred stops the motor drive control. Then, the motor drive control is continued by the control calculation unit of the normal system in both actuators.
