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.

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.

A biaxial type gear transmission comprises a plurality of gear sets (G1 to G5 and Gr) arranged in pairs. A sleeve (33, 34, 35) is disposed between the two gear sets (G1 and G4; G2 and G5; G3 and Gr) of each pair. Power transmission from an input shaft (31) to an output shaft (32) is established or interrupted by axial movement of the sleeves (33, 34, 35), and power transmission from the input shaft to the output shaft at a certain gear ratio is established by selection of a certain gear set based upon an operation of a shift operating mechanism. The gear sets of each pair face each other and are disposed with a nonconsecutive order of shift stage, so that shift transfers are effected by moving two of the sleeves (33, 34, 35) simultaneously.

A vehicle gear transmission includes a switching means (41), a switch mode judging means (112), and a shift stage identification means (202). A shift mode of the transmission is switched between an automatic shift mode and a manual shift mode by the switching means (41). The switch mode judging means (112) senses when the transmission has been switched from the automatic shift mode to the manual shift mode by the switching means (41). The shift stage identification means (202) identifies the selected shift stage in the automatic shift mode at the instant when the automatic shift mode is switched to the manual shift mode. Further, the shift stage identification means identifies when the selected shift stage in the automatic shift mode of the transmission is an overdrive shift stage at the instant when the automatic shift mode was switched to the manual shift mode. In this case, a shift-down operating means (203) shifts-down the shift stage of the transmission from the overdrive shift stage at the time of transition from automatic to manual mode when a vehicle speed judging means (106) judges that the vehicle speed is higher than a predetermined vehicle speed.
