An attitude control system controls a seat sliding, a seat reclining, a seat vertical, a head rest, a seat belt anchor, a steering tilting, a steering telescoping and a mirror position or attitude. The system includes a master controller and a slave controller, and a key switch which provides an attitude control command is only connected to the master controller. In response to the attitude control command from the key switch, the master controller delivers an attitude control command which is then transmitted to the slave controller. In order to avoid an interference which may occur between different mechanisms, a sequence in which the attitude control takes place is automatically switched depending on the direction in which the attitude of other mechanisms is controlled or depending on the prevailing controlled status of other mechanisms.

Attitude control system with independent controllers for controlling

An imaginary limit position is determined on the basis of a position where an overload condition is detected, and such imaginary limit position is stored. Subsequent to the storage, an extent of movement is limited to that defined by the limit position. An operational mode which re-establishes a stored position is provided. In response to the detection of an overload condition, a motor is reversed to move the attitude back through a small stroke, whereupon the motor is deenergized. When a manual switch is turned on, the motor is driven over an incremental time interval and is then deenergized temporarily. After a given time interval, the motor is again driven. Where a pluarlity of motors are driven simultaneously, the timing of initiating to drive each motor is displaced relative to each other by a small time increment during which a transient current occurs upon initiating the drive.
