Abstract: A vehicle driving system control apparatus includes a power transmission device and a power transmission control section. The power transmission device includes an engine input shaft, a motor input shaft, an output shaft, an engine-side gear mechanism transmitting a power of the engine input shaft to the output shaft, a motor-side gear mechanism transmitting a power of the motor input shaft to the output shaft, a first clutch enables and disables a power transmission between the engine input shaft and the motor input shaft, a second clutch enables and disables a power transmission between the motor-side gear mechanism and the output shaft, and a third clutch enables and disables a power transmission between the engine-side gear mechanism and the output shaft. The power transmission control section determines statuses of the clutches and required torques of motor generators in correspondence with a rotation speed of an axle.

Abstract: A centrifugal blower includes an impeller and a casing having an air intake portion. The air intake portion has a bell mouth lower end portion that includes a downstream end, and a bell mouth inner surface portion that includes a radially inner surface. The shroud has a shroud upper end portion that includes an upstream end, and a shroud inner surface portion that includes a radially inner surface. The bell mouth lower end portion and the shroud upper end portion face each other in the axial direction across a gap. A difference between a diameter smallest in the bell mouth inner surface portion and a diameter smallest in the shroud inner surface portion is equal to or smaller than a thickness of the shroud. A vertical vortex generating mechanism configured to generate a vertical vortex is provided on the bell mouth inner surface portion.

Abstract: A centrifugal blower includes a rotation shaft, an impeller, a casing. The impeller includes a plurality of blades and a side panel. The casing accommodates the impeller and includes an air intake portion positioned adjacent to the side panel. The air intake portion includes a downstream end portion and an inner wall surface. The side panel includes an upstream end portion and an inner panel surface that is an inner surface of the side panel. The downstream end portion and the upstream end portion face each other across a space in an angular range. A difference between a smallest inner radius of the inner wall surface of the air intake portion and a smallest inner radius of the inner panel surface is smaller than or equal to a thickness of the side panel in the angular range.

Abstract: A vehicle driving system control apparatus includes a regeneration control section that performs a regeneration control when a vehicle is decelerated. In the regeneration control, the regeneration control section drives at least one of a first motor generator and a second motor generator with a power of an axle so as to charge a battery with an electric power generated with the at least one of the first motor generator and the second motor generator. The regeneration control section selects a mode of the regeneration control by controlling engagement and disengagement statuses of first to third clutches in correspondence with at least one of a target energy regeneration amount, a required brake torque and a vehicle speed.
