Vehicle remote convenience receiver unit having multiple energy saving sleep modes
First Claim
1. A remote convenience receiver unit associated with a vehicle for receiving a remote convenience signal conveying a remote convenience function request and for causing performance of the requested function at the vehicle, said receiver unit consuming a first amount of energy while awaiting reception of the remote convenience signal at an ability to readily receive the remote convenience signal, said receiver unit comprising:
- means for monitoring duration of inactivity caused by a lack of receipt of a remote convenience signal;
means for reducing functional operation of said receiver unit to consume a second, lesser amount of energy after a first duration of inactivity; and
means for reducing functional operation of said receiver unit to consume a third, lesser and different amount of energy after a second, different duration of inactivity.

Abstract
A remote convenience receiver unit (12), which is associated with a vehicle (16), receives a remote convenience signal (20) that conveys a remote convenience function request and causes performance of the requested function at the vehicle. The receiver unit (12) consumes a first amount of energy while awaiting reception of the remote convenience signal (20) at an ability to readily receive the remote convenience signal. A signal monitor and duty-cycle control (82) monitors duration of inactivity caused by a lack of receipt of a remote convenience signal (20), causes reduction of functional operation of the receiver unit (12) to consume a second, lesser amount of energy after a first duration of inactivity, and causes reduction of functional operation of the receiver unit to consume a third, lesser and different amount of energy after a second, different duration of inactivity.

7. A remote convenience receiver unit associated with a vehicle for receiving a remote convenience signal conveying a remote convenience function request and for causing performance of the requested function at the vehicle, said receiver unit comprising:
-
means for receiving the remote convenience signal, said means for receiving being able to receive the remote convenience signal in response to provision of energy;
means for monitoring duration of inactivity caused by a lack of receipt of a remote convenience signal;
means for duty-cycling energy to said means for receiving at a first rate after a first duration of inactivity; and
means for duty-cycling energy to said means for receiving at a second, different rate after a second, different duration of inactivity.
