Abstract: A steering controller that controls a motor to output an assist torque to steer a steering member, including a steer property calculator calculating a steer state quantity that is an index of a steering state indicating one of (i) a steer-away state, (ii) a steer-back state, or (iii) a stay-still state, an adjusted torque calculator calculating an adjusted torque based on the steer state quantity, and an instruction value calculator calculating an assist torque instruction that is an instruction value regarding a drive of the motor by using the adjusted torque. In such manner, the steer state quantity, the steer-back operation, the stay-still operation of a steering wheel, and the adjusted torque are appropriately calculated, thereby enabling an appropriate adjustment of a steering feel.

Abstract: An ultrasonic sensor includes: an ultrasonic element provided to transmit or receive an ultrasonic wave propagating along a directional axis; and an element housing case that includes a case diaphragm having a thickness direction along the directional axis. A resonant space is defined between the case diaphragm and the ultrasonic element for the propagating wave, by housing the ultrasonic element while separating the ultrasonic element from the case diaphragm. A horn shape is defined in the element housing case in which a width of the resonant space in a direction orthogonal to the directional axis is reduced as the resonant space extends in an axial direction parallel to the directional axis.

Abstract: A steering control device is configured to control steering via a steering actuator of a vehicle. The steering control device includes a condition determination unit and a steering maintenance unit. The condition determination unit is configured to determine whether a maintenance condition required to keep a steering angle at a stop control angle is satisfied, the steering angle being given by the steering actuator to a tire of the vehicle, the stop control angle being the steering angle which is to be given at a stop position where the vehicle stops traveling. The steering maintenance unit is configured to keep the steering angle at the stop control angle in a pre-stop traveling section in which the vehicle travels until the vehicle arrives at the stop position after the maintenance condition is satisfied.

Abstract: In a return control unit, a driver steering correcting unit calculates a correction amount outputted in relation to any calculation quantity in a calculation process for a return control amount, based on a steering torque and steering wheel position-related information, such that the return control amount is maintained or increased when a steering torque is applied in a returning direction towards a neutral position of a steering wheel, and the return control amount is reduced when the steering torque of which an absolute value is equal to or greater than a predetermined critical value is applied in a turning direction away from the neutral position of the steering wheel. The steering wheel position-related information is information of which a value when the steering wheel is at the neutral position is zero and the value is positive or negative based on a steering wheel position in relation to the neutral position.

Abstract: A resin-bonded body of a fuel injection apparatus includes a first resin material and a second resin material, which are bonded together and have different properties, respectively. The resin-bonded body has a fuel seal portion to limit leakage of fuel from a boundary surface between the first resin material and the second resin material to an outside. The fuel seal portion is formed in a portion of the boundary surface and is surface-modified to increase hydrophilicity of the fuel seal portion.
