Abstract
A vehicle includes: receiver(s), a timer counting time, memory, and processor(s) configured to: receive a timestamped signal from a fob; compare the timestamp to a time window; reject the timestamp if the timestamp is outside the time window; expand the time window with the counted time; compute the time window as a trigonometric function of the counted time and a predetermined angle.
Claims18
A vehicle comprising:
- a receiver, timer counting time, memory, and processor configured to:
- receive a timestamped signal from a fob;
- compare the timestamp to a time window;
- reject the timestamp if the timestamp is outside the time window;

A vehicle comprising:
- a receiver, timer counting time, memory, and processor configured to:
- receive a timestamped signal from a fob;
- compare the timestamp to a time window;
- reject the timestamp if the timestamp is outside the time window;
- expand the time window with the counted time;
- and,
- enable user selection, via a vehicle display, of a maximum predetermined time, compare the maximum predetermined time to the counted time, and when the counted time exceeds the maximum predetermined time, accept the timestamp if the timestamp is outside the time window.

A method of controlling a vehicle including:
- a receiver, timer counting time, memory, and processor, the method comprising, with the processor:
- receiving a timestamped signal from a fob;
- comparing the timestamp to a time window;
- rejecting the timestamp if the timestamp is outside the time window;
- expanding the time window with the counted time;
- and,
- enabling user selection, via a vehicle display, of a maximum predetermined time, comparing the maximum predetermined time to the counted time, and when the counted time exceeds the maximum predetermined time, accepting the timestamp if the timestamp is outside the time window.
