    Abstract: A steering assist control system causes multiple actuator units to control an assist torque that provides assistance in steering in accordance with a turning operation on a steering wheel in a vehicle having an information presentation apparatus. The steering assist control system includes: a monitoring part that monitors the actuator units; a torque control part that reduces, in a case of a one-unit anomaly, the assist torque that results from combining output torques from all the actuator units, when the turning operation is performed on the steering wheel; and a warning control part controls the information presentation apparatus. In the case of the one-unit anomaly, the torque control part reduces the assist torque so that the assist torque is smaller than an assist torque output before the occurrence of the one-unit anomaly, every time the turning operation proceeds by a set angle.

    Abstract: A dynamic quantity sensor includes a first substrate and a second substrate. The first substrate has one surface, another surface opposite to the one surface, and a depressed portion defining a thin portion. The second substrate has one surface attached to the first substrate and a recessed portion disposed corresponding to the depressed portion. At least a part of a first projection line obtained by projecting the recessed portion is disposed outside of a second projection line obtained by projecting a boundary line between side walls of the depressed portion and the thin portion. The thin portion disposed inside the periphery of the recessed portion provides a film portion which is displaceable corresponding to a physical quantity applied to the film portion, and a region sandwiched between the film portion and a portion connected to the periphery of the recessed portion provides a stress release region.
