A system and method for remote activation of a device includes, in one embodiment, receiving a signal indicative of a range from the device, comparing the range to a threshold, selecting a first transmission protocol when the range exceeds the threshold, selecting a second transmission protocol when the range fails to exceed the threshold, and transmitting a command signal according to the selected first or second transmission protocol.
摘要:
A system and method for remote activation of a device includes, in one embodiment, transmitting a command message according to a first modulation, and transmitting a signal representing the command message for the device according to a second modulation. The signal representing the command message transmitted according to the second modulation may be transmitted within the command message transmitted according to the first modulation.
摘要:
A system and method for tire pressure monitoring. The system includes a receiver having a storage memory, and a transmitter corresponding to a tire. The storage memory includes a set of unique identifier. The transmitter includes a programmable memory. The receiver is configured to receive a signal, determine when the signal corresponds to a member of the set of unique identifiers, and process the signal when the signal corresponds to a member of the set of unique identifiers. The transmitter is configured to receive a unique member of the set of unique identifiers, store the unique member in the programmable memory, and transmit a signal corresponding to the unique member and the air pressure in the tire.
摘要:
A seat folding apparatus is provided with a passive Rf frequency link that requires that a person be within a certain limited distance from the vehicle to operate the seat folding mechanism. A foreign object detection system, such as a plurality of weight sensors, is provided in the seat to detect foreign objects on the seat.
摘要:
In one embodiment of a system and method for remote activation of a device includes, a transceiver is provided for transmitting a command signal according to a first transmission protocol having a first data rate, receiving an acknowledgment signal indicating that the command signal transmitted according to the first transmission protocol has been received, and transmitting the command signal according a second transmission protocol, the second transmission protocol having a second data rate less than the first data rate and including partition of the command signal. A controller is provided for selecting the first transmission protocol for use in transmitting the command signal in response to a user input, and selecting the second transmission protocol for use in transmitting the command signal when the transceiver fails to receive the acknowledgment signal.
摘要:
A system and method for receiving signals from a tire pressure monitoring (TPM) system, a remote keyless entry (RKE) system, and a passive entry system in a manner that reduces the occurrence of signal interference includes transmitting at least a first signal to a receiver on the vehicle. The receiver is configured to have multiple channels for receiving the TPM signal, the RKE signal and/or the passive entry signal. The method also includes receiving the first signal on a first receiver channel. The method further includes selecting a second receiver channel for receiving at least a second signal when the second signal is or will be generated.
摘要:
A system and method for remote activation of a device includes, in one embodiment, transmitting a command message according to a first modulation, and transmitting a signal representing the command message for the device according to a second modulation. The signal representing the command message transmitted according to the second modulation may be transmitted within the command message transmitted according to the first modulation.
摘要:
A folding system for a vehicle seat is disclosed that includes a Rf transmitter that is associated with the seat and a receiver that polls a portable transmitter/receiver whenever it is within a targeted zone near the rear door, right side door, or left side door. Weight sensing sensor arrays in the folding seat are used to prevent folding the seat when a foreign object is disposed in the seat. A Rf receiver may be provided either as part of the vehicle seat or the Rf receiver of a remote keyless entry system can be used that communicates with the seat through a vehicle bus.
