Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
190 words
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.
Claim 2
Dependent Claim
190 words
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.
Claim 3
Dependent Claim
97 words
The attitude control system according to claim 1 in which the attitude adjusting means includes at least one first adjusting mechanism which adjusts the attitude of a seat, and at least one second adjusting mechanism which adjusts the attitude of a steering column, the master and the slave electronic control means being operative to inhibit the operation of the second adjusting mechanism at least until the operation of the first adjusting mechanism is completed whenever the presence of the attitude control command to the second adjusting mechanism is detected during the operation of the first adjusting mechanism.
Claim 4
Dependent Claim
66 words
The attitude control system according to claim 1 in which one of the master and the slave electronic control means controls the plurality of attitude adjusting means, the sequence in which these attitude adjusting means are subject to an attitude control being switched in accordance with the condition of attitude control which is performed by the other of the master and the slave electronic control means.
Claim 5
Dependent Claim
71 words
The attitude control system according to claim 1 in which the attitude adjusting means includes at least a seat slide adjusting mechanism and a seat reclining adjusting mechanism, the master and the slave electronic control means automatically changing the sequence in which the seat slide adjusting mechanism and the seat reclining adjusting mechanism are adjusted depending on the direction in which the attitude of the seat reclining adjusting mechanism is controlled.
Claim 6
Dependent Claim
78 words
The attitude control system according to claim 1 in which the attitude adjusting means includes at least one first adjusting mechanism which adjusts the attitude of a seat, and at least one second adjusting mechanism which adjusts the attitude of a steering column, the master and the slave electronic control means automatically changing the sequence in which the seat attitude and the steering column attitude are controlled depending on the direction in which the seat attitude is controlled.
Claim 7
Dependent Claim
