APPARATUS FOR AUTOMATICALLY CHANGING STATE OF VEHICLE CLOSURE
First Claim
1. An apparatus for changing the state of a vehicle closure, the apparatus comprising:
- a primary mobile unit;
a secondary mobile unit;
a detection device operable to automatically detect whether the primary mobile unit is within a first range of the detection device, and whether the secondary mobile unit is within a second range of the detection device; and
a controller operable to change the state of the vehicle closure when the detection device detects that the secondary mobile unit is within the second range while the primary mobile unit is being detected within the first range.

18. An apparatus for changing the state of a vehicle closure, the apparatus comprising:
-
a primary mobile unit; a secondary mobile unit; a detection device operable to transmit a primary interrogation signal within a first range and an energizing signal within a second range, wherein the primary mobile unit is operable to transmit a primary identification signal in response to the primary interrogation signal, wherein the secondary mobile unit is operable to obtain energy from the energizing signal and transmit a secondary identification signal, wherein the detection device detects whether the primary mobile unit is within the first range by matching the primary identification signal to a predetermined primary identifier, and wherein the detection device detects whether the secondary mobile unit is within the second range by matching the secondary identification signal to a predetermined secondary identifier; and a controller operable to change the state of the vehicle closure when the detection device detects that the secondary mobile unit is within the second range while the primary mobile unit is being detected within the first range, wherein the state of the vehicle closure changes by at least one of changing the state of the vehicle closure from a locked state to an unlocked-standby state and changing the state of the vehicle closure from a closed state to an open state. - View Dependent Claims (19, 20)
