An automated manual transmission system for a vehicle shifts a shift stage of an automated manual transmission (30) to a shift stage required by an operation of the shift lever (61) after the shift stage of the automated manual transmission is set at a first predetermined shift stage different from the shift stage required by the operation of the shift lever on the condition that the sleeve (44, 45, 46) and the gear set (G1, G4) have not been synchronized when an engine (10) has been stationary and a sleeve can not be moved in an axial direction for shifting the shift stage of the automated manual transmission to the shift stage required by the operation of the shift lever.

摘要:
When a gear position at a higher speed range than a "specific gear position at a lower speed range" (e.g., first speed) is determined (when the torsional vibration is difficult to occur), a clutch torque is controlled such that a clutch is in a totally engagement state (a revolution speed Ne of an output shaft of an engine = revolution speed Ni of an input shaft of a transmission). On the other hand, when the "specific gear position at the lower speed range" (e.g., first speed) is determined (when the torsional vibration is easy to occur), the clutch torque is controlled such that the clutch is in the semi-engagement state (Ne ― Ni = predetermined positive value A). In the semi-engagement state, a "damping action by a slip on the clutch" is acted on the torsional vibration, whereby the amplitude of the torsional vibration can be reduced.

A creep torque control apparatus of a vehicle for outputting a creep torque required to perform a creep running by controlling a load of a clutch disc toward a flywheel rotating as a unit with an output shaft of an engine characterized in that the creep torque control apparatus further includes a detecting means for detecting a vehicle speed, a measuring means for measuring an elapsed time from an output start of the creep torque and a changing means for changing a value of the creep torque based on a relationship between the vehicle speed and the elapsed time.
摘要:
A control device is provided for an actuator which includes an electric motor (32) fixed to a housing (33), a worm (34) rotated by the electric motor, a worm wheel (35) rotatably supported by the housing and meshed with the worm, a stop means (33a) contactable with the worm wheel when the worm wheel is rotated to an angle which is equal to or larger than a predetermined angle, and an electric control device for controlling an operation of the actuator. The control device further includes a driving means (46) for driving the electric motor, a contact judging means (41) for judging that the worm wheel is in contact with the stop means; and a memorizing means (45) for memorizing information corresponding to a rotation angle of the worm wheel as an initial position of the actuator when the judging means judges that the worm wheel is in contact with the stop means.
