Dead switch vehicle operator identification
First Claim
1. An operator identification system by which different operators of a vehicle such as an automobile can identify themselves to a central processing unit for the vehicle comprising:
- a source of operating power;
a vehicle ignition switch coupled to said source for selectively applying power for the ignition of a vehicle and for a plurality of accessory control switches;
a plurality of control switches which are activated only upon the closure of said vehicle ignition switch for applying power from said source for controlling vehicle accessories; and
circuit means for comparing the closure state of each of said plurality of switches and the closure state of said ignition switch and providing an operator identification signal when one of said plurality of said switches assigned to a particular operator is activated and said ignition switch is in an open position, said circuit means including a central processing unit including stored operator accessory preference data for responding to said operator identification signal to control vehicle accessories according to the stored preference data.

Abstract
An operator identification system utilizes "dead" switches, such as window actuating switches which have no control function until such time as a vehicle ignition is turned on, for identifying a particular vehicle operator. The inactive switch contact closure is detected by an electrical circuit which also tests to determine whether the ignition is off and if it is, the window switch closure provides an operator identification signal to a vehicle microprocessor for identifying a particular driver and preset option functions associated with that driver.

6. A system for employing inactive electrical switches to provide signals for identifying a vehicle operator to a vehicle computer comprising:
-
a source of operating power; a vehicle power switch coupled to said source for applying power to a plurality of vehicle accessory control switches; means for providing a first electrical signal representative of the activation state of said vehicle power switch; a plurality of accessory control switches coupled to said power switch for selectively providing power to vehicle accessories to which said control switches are coupled when said power switch is in a closed state for controlling vehicle accessories; and circuit means for comparing the closure state of each of said plurality of switches and said first electrical signal and providing an operator identification signal when one of said plurality of said switches associated with a particular operator is activated and only when said first control signal indicates that said power switch is in an open state, wherein said circuit means includes a central processing unit including memory means storing operator preference data for vehicle accessory controls for at least one operator, and wherein said circuit means responds to the receipt of said operator identification signal to control vehicle accessories according to the stored preference data for the identified operator. - View Dependent Claims (7, 8, 9, 10, 11)

12. A dead switch operator identification system by which different operators of a vehicle such as an automobile can identify themselves to a central processing unit for the vehicle by using switches which are inactive for use in their normal controlling function comprising:
-
a source of operating power; a vehicle ignition switch coupled to said source for selectively applying power for the ignition of a vehicle and for controlling power applied to a plurality of power window control switches; a plurality of power window control switches which are activated upon the closure of said vehicle ignition switch for selectively controlling vehicle widows, wherein each of said power window control switches is associated with at least one vehicle operator; and circuit means for comparing the closure state of each said plurality of power window control switches and the closure state of said ignition switch and providing an operator identification signal when one of said plurality of said window switches associated with a particular operator is activated and only when said ignition switch is open, said circuit means including a central processing unit including stored operator accessory preference data for responding to said operator identification signal to control vehicle accessories according to the stored preference data. - View Dependent Claims (13, 14)
