Apparatus and method for receiving signals in a vehicle

摘要

At a vehicle, a first signal is received and the first signal is of an ASK-compliant modulation type. A second signal is received and the second signal is of a FSK-compliant modulation type. Based upon a set of predetermined criteria, one of the first signal and the second signal is selected, the predetermined criteria at least in part indicating a priority as between ASK-compliant and FSK-compliant communications. The selected signal is transmitted to a vehicular controller over a single transmission line.

1. A method of receiving signals of multiple types, the method comprising:
at a vehicle:
receiving a first signal, the first signal being of an ASK-compliant modulation type;receiving a second signal, the second signal being of a FSK-compliant modulation type;based upon a set of predetermined criteria, selecting one of the first signal and the second signal, the predetermined criteria at least in part indicating a priority as between ASK-compliant and FSK compliant communications;transmitting the selected signal data to a vehicular controller over a single transmission line;wherein the predetermined criteria comprise at least one of:whether a received low priority frame is an actual low priority frame rather than a reflection;whether the actual low priority frame is being recreated; and whether a valid high priority frame is being received;selectively storing one of the high priority frame and the low priority frame in a buffer, wherein selectively storing comprises choosing between at least two of completely storing, partially storing, and not storing;recreating a frame, at least partially, at a faster data rate than the data rate at which the frame was received.
