Abstract: A high voltage board includes a P busbar, an N busbar, and an output busbar. The P busbar, the N busbar, and the output busbar extend in a circumferential direction. In the output busbar, an output current flows in an overlap region from an upper arm switch unit toward a lower arm switch unit. In the P busbar, a P current flows in the overlap region from a smoothing capacitor portion toward the upper arm switch unit in a reverse direction to the output current. In the N busbar, an N current flows in the overlap region from the lower arm switch unit toward the smoothing capacitor portion in a reverse direction to the output current.

Abstract: An inverter device includes an inverter housing. The inverter housing includes an inverter outer peripheral wall and multiple beam portions. The inverter outer peripheral wall has an inner peripheral surface and extends annularly around an inverter axis. The beam portion extends toward a radially inner side from the inverter outer peripheral wall. The multiple beam portions are arranged in a circumferential direction along the inner peripheral surface. The inverter device includes a high voltage board and a drive board. The high voltage board and the drive board extend in a plate shape in a direction orthogonal to an axial direction. The high voltage board and the drive board are fixed to the multiple beam portions while extending across the multiple beam portions. Mounted components such as a smoothing capacitor portion are mounted on the high voltage board and the drive board.

Abstract: An inverter device includes an inverter housing and an arm switch unit. The inverter housing includes an inverter outer peripheral wall and an inverter fin. The inverter outer peripheral wall has an outer peripheral surface and an inner peripheral surface and extends annularly around an inverter axis. The inverter fin is provided on the outer peripheral surface and extends toward a radially outer side from the outer peripheral surface. Multiple arm switch units are arranged in a circumferential direction and are fixed to the inner peripheral surface. The arm switch unit is a heat generation component that generates heat by energization. Heat transferred to the inner peripheral surface from the arm switch unit is dissipated to the outside from the outer peripheral surface of the inverter outer peripheral wall.

Abstract: A shift control apparatus for an automatic transmission of a vehicle wherein a plurality of speed ratios are achieved by electronically controlling individual hydraulic pressures supplied to a plurality of frictional engaging elements to selectively engage these frictional engaging elements, which includes speed ratio select members for changing over the speed ratio of the automatic transmission from a neutral position to a running position, operation condition determination members for determining operation condition of the vehicle, an electromagnetic valve for controlling hydraulic pressure supplied to a first frictional engaging element to achieve a first speed; and electromagnetic valve control members for controlling operation of the electromagnetic valve so that when the speed ratio select members is determined by the operation condition determination means to be slowly manipulated, a supply time of a maximum hydraulic pressure to the first frictional engaging element is extended by a predetermined time

Abstract: Hydraulic pressure supplied to the frictional engaging element of an automotive transmission is corrected to a higher value in the event that the engine is started after a long standstill condition and the first speed ratio is selected, thereby reducing speed-shift shocks when the engine is started from a standstill condition and the first speed ratio is selected.

Abstract: A direct-coupling control method capable of improving fuel efficiency by performing slip direct-coupling control of a torque converter, in which a driving force transmission of an automatic transmission is operated under an approximate direct-coupling condition that permits slight slippage of the torque converter, in a predetermined operating range of the automatic transmission such as a low speed range thereof, and capable of positively detecting and preventing direct-coupling vibration caused by deterioration of hydraulic oil or the like.
