Abstract: A motor control device includes a table in which a motor torque generated from a reluctance torque utilizing motor is stored with respect to a combination of an armature current command value and a current phase angle command value at which the motor torque is maximized for the armature current command value, a first setting portion that sets a motor torque command value that is a command value of a motor torque to be generated by the reluctance torque utilizing motor, and a second setting portion that sets, based on the table, an armature current command value and a current phase angle command value for making a motor torque that is in accordance with the motor torque command value set by the first setting portion be generated from the reluctance torque utilizing motor.

Abstract: A motor control device includes: a second setting unit configured to set an armature current command value and a current phase angle command value based on a rotation speed and a motor torque command value; and a current vector setting unit configured to set a d-axis current command value and a q-axis current command value based on the armature current command value and the current phase angle command value. The second setting unit is configured to set the armature current command value and the current phase angle command value such that an armature current vector which is set based on the d-axis current command value and the q-axis current command value is included in an area surrounded by an armature current vector locus in maximum torque/current control and a vertical axis in a d-q coordinate system.

Abstract: There is provided a vibration control bush that allows improving durability. Formation of an outer periphery depressed portion 326 in an outer peripheral surface of a main body portion 20 forms a thickness dimension D3 in a radial direction of the main body portion 20 in a region overlapping with a projecting portion 340 in an axis 0 direction to be thinner than a thickness dimension D4 in another region where the projecting portion 340 is not formed. Accordingly, an outer diameter (a thickness in the radial direction) of the main body portion 20 in a compressed state of the projecting portion 340 is allowed to be easily made constant in a circumferential direction. This allows suppressing concentration of stress during the compression of the projecting portions 340 on a part of the main body portion 20, thereby ensuring improving durability of vibration control bushes 310 and 410.

Abstract: An airbag device includes an airbag, straps, and strap covers. The airbag is stored in a cowl portion. The airbag configured to be deployed on the front surface side of windshield glass, and to cover the cowl portion and front pillars at least in part. A first end of each of the straps is attached to an upper portion of an outer surface of the airbag in the vehicle up-down direction and a second end of each of the straps is attached to the cowl portion. The straps pass between the airbag and the strap covers. The strap covers are sewn to the outer surface of the airbag and cover the straps.

Abstract: A pedestrian protection airbag device has an airbag case that is provided on a bottom surface side of a rear end portion of a vehicle hood, an airbag that includes a hood underside bag portion that is housed inside the airbag case and is inflated and deployed towards the vehicle rear side by pressure from gas which is generated by an inflator, and that is laid out on a bottom surface side of the hood, and that also includes a bag main body portion that is connected to the hood underside bag portion and that is inflated and deployed towards the vehicle top surface side from between a rear end portion of the hood and a glass windshield, and vertical joining portions that join the airbag vertically and reduce the thickness in the vehicle up-down direction of the hood underside bag portion in the inflated and deployed state.

Abstract: A power circuit abnormality detection method for a power circuit detects whether an abnormality in a power source relay exists. The power circuit includes a pre-charge circuit opening and closing a connection between a direct current power source and a smoothing condenser by bypassing the power source relay to pre-charge the smoothing condenser, and a discharge circuit connected in parallel to the smoothing condenser to discharge electric charges stored in the smoothing condenser via a discharge resistance when a discharge switch is closed. The power circuit abnormality detection method includes a step of detecting whether the open contact abnormality in the power source relay exists based on whether a charge voltage of the smoothing condenser is reduced when a predetermined period of time has elapsed since both the discharge circuit and the power source relay are closed after the pre-charge circuit is opened.

Abstract: A vehicle control device of a rotary electrical machine control device includes an application voltage generation unit that generates a voltage control signal that is used to apply a power supply voltage to a DC/DC converter at a voltage equal to or higher than the power supply voltage or at a voltage lower than the power supply voltage; and a voltage command value generation unit that generates a motor control signal that controls a drive motor. The voltage command value generation unit performs computation based on overmodulation PWM control as PWM control in the case where the application voltage that is lower than the power supply voltage is applied so as to output the motor control signal having a pulse width longer than a cycle of a PWM carrier.
