  • Publication number: 20240084753
    Abstract: A control device and method controls a vehicle having an internal combustion engine connected to an automatic transmission via a torque converter with a lockup device. The torque of the internal combustion engine is limited the by a torque limit value based on a speed difference between an input rotational speed and an output rotational speed of the torque converter during acceleration in a non-lockup state. The torque-limiting of the internal combustion engine is prohibited torque-limiting upon a prescribed condition being met. The prescribed condition is met by a heating request, during hill climbing/towing, during travel at high vehicle speeds, when the accelerator pedal opening angle exceeds or is equal to a prescribed opening angle, when the torque limit value is greater than a target torque, in a range other than a D range, or in a mode other than normal mode.

  • Publication number: 20240044404
    Abstract: [PROBLEMS] When an acceleration request from a driver is large, upshift is performed under a high engine rotation speed. [SOLUTIONS] Provided is an automatic transmission, including: a torque converter that is disposed downstream of a drive source in a power transmission path and is provided with a lockup clutch; and a transmission mechanism that is disposed downstream of the torque converter and changes a speed ratio between an input shaft and an output shaft, in which in a state where the lockup clutch is engaged, when a rotation speed of the input shaft reaches a first rotation speed, the automatic transmission starts upshift, and in a state where the lockup clutch is disengaged or slips, when the rotation speed of the input shaft reaches a second rotation speed obtained by subtracting a first predetermined rotation speed from the first rotation speed, the automatic transmission starts upshift, and the first predetermined rotation speed decreases as an output torque of the drive source increases.

  • Patent number: 11326691
    Abstract: A belt-type continuously variable transmission includes a primary pulley, a secondary pulley, and a belt wound around the primary pulley and the secondary pulley. A controller performs a process, when performing a low speed position return shift to shift a transmission ratio toward a lowermost speed position while a vehicle is decelerating. The process includes: calculating a primary pressure actual lower limit, at which the belt actually starts to slip, based on the transmission ratio and a deceleration of the vehicle; setting a lower limit of a setpoint of the primary pressure to the primary pressure actual lower limit; setting the primary pressure actual lower limit higher with a locking tendency of a vehicle wheel detected than that without the locking tendency detected; and setting the primary pressure actual lower limit with the locking tendency detected to increase as the transmission ratio varies toward the lowermost speed position.

  • Publication number: 20180174989
    Abstract: The present disclosure relates to a production process for a solder electrode, including a step (1) of forming a coating film of a photosensitive resin composition on a substrate having an electrode pad; a step (2) of forming resist having an opening in a region corresponding to the electrode pad by selectively exposing the coating film to light and further developing the film; a step (3) of heating and/or exposing the resist to light; and a step (4) of filling the opening with molten solder while heating the solder. According to the production process for the solder electrode of the present disclosure, development of cracks on a resist surface can be prevented, and solder filling capability can be improved, even when the resist receives high heat during solder filling as in an IMS method, and therefore the solder electrode adapted for the purpose can be appropriately produced.

  • Patent number: 6067703
    Abstract: A combined thin film magnetic head includes a magnetoresistive reproducing head part and an inductive recording head part. The magnetoresistive reproducing head part is defined between a lower shielding layer and a merged core layer. The inductive recording head part is defined between the merged core layer and an upper core layer and is configured to specify a track width for the recording head part by providing the upper core layer in a localized region W.sub.2. A method of fabricating the magnetic head includes steps of forming an etching-protective layer on a gap layer so as to provide an exposed region W.sub.1 left uncovered which is larger than the localized region W.sub.2 in which the upper core layer is to be finally confined, depositing the upper core layer over the entire surfaces thereof, and etching the upper core layer so as to finally confine the etched upper core layer in the localized region W.sub.2.
