Attitude control system with independent controllers for controlling onboard units
First Claim
1. An attitude control system for onboard units comprising:
- a plurality of attitude adjusting means each including electric drive means operable to adjust the attitude of each of mutually different onboard units;
at least one master switch means for delivering a primary attitude control command related to all of the plurality of attitude adjusting means;
master electronic control means operable in accordance with a given control program and connected to the master switch means and at least one of the plurality of attitude adjusting means for controlling the at least one connected attitude adjusting means in response to the primary attitude control command and for delivering a secondary attitude control command in response to the primary attitude control command; and
slave electronic control means operable in accordance with an independent control program which is separate from the program associated with the master electronic control means and connected to the remaining ones of the plurality of attitude adjusting means and the master electronic control means for controlling the connected ones of the plurality of attitude adjusting means in response to the secondary attitude control command delivered by the master electronic control means.

Abstract
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.
