摘要： According to a torque converter lockup control, a lockup actuator, including a lockup solenoid, is operative responsive to an output command signal issued by a controller to adjust lockup clutch engagement force to a commanded value. The lockup clutch engagement force is a force with which the lockup clutch is engaged. The controller determines the commanded value as a function of a deviation between a current value of slip speed within the torque converter and a desired value thereof. For preventing the lockup clutch from shifting deeply into its converter position when the deviation persists to stay in the neighborhood of zero, the controller sets a limit to the determined commanded value during operation of the lockup clutch in the slip lockup mode.

摘要： A lockup control apparatus for use with an automotive vehicle having an engine, an automatic transmission and a torque converter operable in a coast lockup mode having a lockup capacity to provide a controlled degree of mechanical connection between the engine and the automatic transmission when the vehicle is coasting. The apparatus employs a memory having a desired value for the lockup capacity stored therein. A first signal is produced when a slip rotation occurs in the torque converter and a second signal is produced when the coast lockup mode is released. The desired lockup capacity value is updated with a greater value in response to the first signal. A frequency at which either of the first and second signals occurs is measured. The desired lockup capacity value is updated with a smaller value when the measured frequency exceeds a reference value. The lockup capacity is controlled based on the desired lockup capacity value stored in the memory to retain the frequency of occurrence of the first signal in a predetermined range.

摘要： An automatic transmission includes at least an input section, an output section, first and second frictional engagement elements, and a controller. The input section receives an input torque from a drive unit. The first frictional engagement element has an engaged state allowing the output section to rotate at a first transmission gear ratio with respect to the input section. The second frictional engagement element has an engaged state allowing the output section to rotate at a second transmission gear ratio with respect to the input section. The controller controls at least a gear shift from the first transmission gear ratio to the second transmission gear ratio. The controller controls the first and second frictional engagement elements and the drive unit so as to cancel an inertia torque resulting from the gear shift.

摘要： A shifting control system has two gear shift stage groups, two clutches, a clutch release detection section, a pre-shift controller, a clutch oil level detection section and a pre-shift inhibiting section. The clutches are alternately engaged to selectively transmit power from an engine to a wheel. The clutch release detection section detects a release-side clutch which corresponds to the clutch that is in a released state. The pre-shift controller operates a meshing mechanism of the gear shift stage group corresponding to the release-side clutch, so as to undergo pre-shifting when the other clutch is engaged as an engage-side clutch. The clutch oil level detection section determines whether an oil level in the release-side clutch is equal to or greater than a preset oil level. The pre-shift inhibiting section inhibits pre-shifting while the oil level in the release-side clutch is equal to or greater than a preset oil level.

摘要： An automatic transmission control apparatus is provided with a control scheme that focuses on the rotational speed differences of the frictional engaging elements and the distribution of torque transferred by the frictional engaging elements. When the automatic transmission is upshifted while in a power-off state, the individual torque capacity of a frictional engaging element being released and the individual torque capacity of a frictional engaging element being connected are corrected by adding a prescribed torque capacity amount to each of the individual torque capacities during an inertia phase of the shift control in which a compensation is executed for inertia related to changing the gear ratio. In this way, frictional losses are induced in the frictional engaging elements so as to absorb the inertia torque and lower the input rotational speed more quickly.

摘要： In a hybrid vehicle wherein the rotation torques of a motor and engine are input to a continuously variable transmission, a drive force is controlled by a microprocessor programmed to set a target drive power (tPO) based on a depression amount of an accelerator pedal (APO) and a vehicle speed (VSP), set a battery power (PB) based on a battery charge amount (SOC), set a target engine power (tPE) based on the target drive power (tPO) and the battery power (PB). The microprocessor is also programmed to set a limited target engine power (tPELMT) to zero when the target engine power (tPE) is less than a predetermined value, and set the limited target engine power (tPELMT) equal to the target engine power (tPE) when the target engine power (tPE) is larger than the predetermined value. The microprocessor is further programmed to set a target engine torque (tTE) and a target engine rotation speed (tNE) based on the limited target engine power (tPELMT), set the target motor/generator torque (tTMG) based on a target motor/generator power (tPMG) and the input rotation speed (NI), and set the target speed ratio (tRVO) based on the target engine rotation speed (NI) and the vehicle speed (VSP).
