摘要:
A controller, control method, and control system for a motor vehicle gear-type transmission enable a friction transmission unit to be controlled to an optimum position according to a particular motor vehicle state or the like. A transmission control unit changes, via at least one parameter that indicates a state of the gear-type transmission or of the vehicle, a position or pressure load at which the pressure member is caused to stand by while the driving shaft of the vehicle is in a stopped state or during changeover of the mesh unit that connects to one of the gear pairs.

In a torque assisted automated MT, an assist clutch is controlled to ensure that the transmission torque increase rate is reduced when disengaging a dog clutch while engaging the assist clutch. In a twin clutch type automated MT, in stepped speed change, one of the two clutches as the twin clutch is controlled in such a way that the transmission torque increase rate resulting from engagement is reduced with the passage of time, when disengaging the dog clutch prior to speed change while engaging the clutch corresponding to the input shaft in charge of offsetting the torque interruption.
摘要:
A vehicle equipped with a motor-operated mechanism that contains a clutch. The pushing member of the clutch is energized against a friction plane by an energizing mechanism and transfers power from a driving power source when it touches the friction plane. The location of the pushing member can be retained even when power is shut off. This structure prevents promotion of deterioration of a diaphragm spring in a state in which the clutch remains disengaged when the key switch is turned off.After a signal from the key switch stops, the control apparatus stops the driving power source and the vehicle, engages the friction transfer mechanism, and then stops the system.

A vehicle control device includes an actual drag torque calculating unit, which calculates the drag torque of a power transfer mechanism. A lubricating oil flow rate calculating unit determines the flow rate of lubricating oil according to the actual torque, and a reference drag torque calculating unit calculates a reference drag torque. In addition, a reference lubricating oil flow rate calculating unit calculates a reference lubricating oil flow rate according to the reference drag torque. A correction rate calculating unit then calculates a correction value corresponding to the rate of correction of the lubricating oil flow rate according to the lubricating oil flow rate and reference lubricating oil flow rate. A flow rate correction unit outputs a drive signal to an actuator which controls a lubrication oil flow rate according to the correction rate.

摘要:
A motor vehicle gear-type transmission has an input shaft clutch, multiple gear pairs, multiple mesh units, and an input shaft clutch actuator which adjusts the position or pressure load of the pressure member of the input shaft clutch. A transmission control unit changes, by means of at least one of the parameters that each indicate a state of the gear-type transmission or of the vehicle, a position or pressure load at which the pressure member is caused to stand by while the driving shaft of the vehicle is in a stopped state or during changeover of the mesh unit that connects to one of the gear pairs. A controller, control method, and control system for a motor vehicle gear-type transmission, adapted to enable a friction transmission unit to be controlled to an optimum position according to a particular motor vehicle state or the like can be provided.

A vehicle clutch has a pushing member that is energized against a friction plane and transfers power from a driving power source when it touches the friction plane. The location of the pushing member can be retained even when power is shut off. After a signal from the key switch ends, the control apparatus stops the driving power source and the vehicle, engages the friction transfer mechanism, and then stops the system.
