An apparatus for controlling ignition timing during a shift in a vehicular automatic transmission is provided that is capable of suppressing shift shock in the event that input torque of the automatic transmission is affected by external changes, such as changes in fuel and air pressure and the like, by adjusting immediately to those changes. This control apparatus is provided with an ignition timing controller that controls an ignition timing retard amount; a calculator that calculates a basic retard amount; a detector that detects an engine retard amount; a determinator that determines a retard correction value based on a shift mode of the automatic transmission and the like; and a corrector that corrects the ignition timing retard amount of the controller based on the retard correction value, the basic retard amount, and the engine retard amount.

In a vehicle in which a moderate throttle opening degree control of maintaining a degree of throttle opening that is less than a degree of throttle opening that corresponds to an accelerator operation is performed for a predetermined period following a beginning of the accelerator operation, if it is determined that a clutch-to-clutch downshift judgment has been made, the reduction of the engaging pressure of a disengage-side friction engagement device is restrained until it is determined that the moderate throttle opening degree control has ended. Therefore, even if the turbine torque is returned to a normal value at the end of the moderate throttle opening degree control, insufficient engaging torque is avoided, and the takeover of engaging torque for the clutch-to-clutch downshift is smoothly performed while the turbine torque is stable. Hence, occurrence of a shock related to the end of the moderate throttle opening degree control is suitably prevented.

A semiconductor device has a case, a printed circuit board, a fin, and a ceramic substrate mounting a semiconductor element thereon. The case contains the printed circuit board, the ceramic substrate and the fin. The fin and the case radiate heat transmitted from the ceramic substrate. The fin has protrusions on a contact face facing a contact face of the case. The fin contacts the case though the protrusions when the fin is fixed to the case. The protrusions serve as heat radiating path.

An apparatus for controlling a lock-up clutch for direct connection of an engine and an automatic transmission of a motor vehicle, the apparatus including a slip control device for selectively placing said lock-up clutch in one of a fully released state, a fully engaged state, and a partially engaged state, an uphill road detecting device for detecting that a road on which the motor vehicle is running is an uphill road; and a slip control inhibiting device for inhibiting the slip control device from placing the lock-up clutch in the fully or partially engaged state, if the uphill road is detected by the uphill road detecting device, so that undesirable repeated switching of the clutch between the fully released state and the fully or partially engaged state during uphill road running of the vehicle is prevented.

A circuit board includes an insulating member and a semiconductor chip encapsulated with the thermoplastic resin portion of the insulating member. A wiring member is located in the insulating member and electrically connected to first and second electrodes on respective sides of the semiconductor chip. The wiring member includes a pad, an interlayer connection member, and a connection portion. A diffusion layer is located between the first electrode and the connection portion, between the pad and the connection portion, and between the second electrode and the interlayer connection member. At least one element of the interlayer connection member has a melting point lower than a glass-transition point of the thermoplastic resin portion. The connection portion is made of material having a melting point higher than a melting point of the thermoplastic resin portion.

An automatic shift control is executed in an automatic transmission with 5 shift speeds of range hold type in the highest gear stage of a shift range at the manual shift mode. Upon selection of a shift mode from the automatic shift mode to the manual shift mode, the shift range at the manual shift mode is selected in accordance with the vehicle speed detected at the automatic shift mode. If the vehicle speed is in the low-speed range, the shift range 3 is selected. If the vehicle speed is in the medium-speed range, the shift range 4 is selected. If the vehicle speed is in the high-speed range, the shift range 5 is selected.
摘要:
A gear position display device includes a transmission having a plurality of gear positions, a speed-changing control portion outputting a speed-changing instruction, a display portion displaying a gear position of the transmission, and a detection portion detecting a speed-changing state of a gear position based on the speed-changing instruction, wherein a gear position based on the speed-changing instruction from the speed-changing control portion is displayed after the detection portion confirms actual starting of speed-changing.
摘要:
A deceleration control device for a vehicle including an automatic transmission capable of changing the gear ratio by a shift operation of a driver. The control device controls the load of a brake actuator or engine so that the vehicle is decelerated, when the driver performs a shift operation, under conditions that it is determined that the driver has the intention to decelerate and the automatic transmission is not downshifted.
