Abstract: An automatic steering control apparatus includes a target-path acquisition unit that acquires a target path that is to be a traveling path of the vehicle, a target-rudder-angle acquisition unit that acquires a target rudder angle that is to be a rudder angle in the vehicle, on the basis of the target path, a sideslip-angle estimation unit that estimates a sideslip angle in the vehicle that is traveling at the target rudder angle, on the basis of the target rudder angle and a vehicle condition of the vehicle, and an automatic steering control unit. The automatic steering control unit performs at least one of stopping of automatic steering control and controlling of a steering-quantity regulation gain for regulating the target rudder angle, when the estimated sideslip angle is equal to or greater than a predetermined value.

Abstract: Provided is an engine starting device, including: starter control means for causing, when the restart condition is established during a period in which a meshing inhibition condition for a ring gear and a pinion gear is established, the pinion gear and the ring gear to mesh with each other after the meshing inhibition condition is released, thereby restarting the engine. The starter control means determines the meshing permission condition and the meshing inhibition condition based on at least an engine rotation speed, and determines the release of the meshing inhibition condition before the engine completely stops based on at least one of the engine rotation speed and an elapsed time after the establishment of the meshing inhibition condition.

Abstract: The engine starter includes: a starter motor; a pinion unit (30) for sliding in an axial direction on an output shaft of the starter motor; and a ring gear (100) which meshes with a pinion pushed out by a push-out mechanism (60) and receives a transmission of a rotational force of the starter motor to thereby start an engine, and the pinion portion (30) includes a pinion gear divided in the axial direction into two pinion gears which are a first pinion gear (35) having a protruded shape for synchronization, for first colliding with the ring gear upon start of meshing with the ring gear, and a second pinion gear (34) for serving to transmit the rotational force after the meshing.

Abstract: An engine starting device includes: a starter motor; a pinion unit coupled to an output-shaft side of the starter motor by a spline, for sliding in an axial direction; and a ring gear which meshes with a pinion gear of the pinion unit pushed out by a push-out mechanism, and receives a transmission of a rotation force of the starter motor, thereby starting an engine. The pinion unit includes, on all teeth on distal end portions in a meshing axial direction of the pinion gear meshing with the ring gear, synchronization surfaces which are a pair of surfaces parallel with the meshing axial direction, and have a thickness thinner than a tooth thickness of the pinion gear.
