An apparatus for performing a desired vehicle function is provided. The apparatus comprises a base station configured to receive a command signal indicative of the desired vehicle function while in a receive mode. The base station is further configured to determine whether the received command signal includes at least one of a data component from a plurality of data components and to activate a transmit mode in the event the received command signal includes the at least one of the data component. The base station is further configured to determine whether the received command signal includes at least one additional data component from the plurality of data components while in the transmit mode and to determine that the portable device is positioned within a predetermined range in the event the received command signal includes the at least one additional data component.

Apparatus and method for dual range detection in a vehicle

A system includes a base station, a communications device, and a fob. The base station is configured to control a vehicle function in response to receiving a command via a first wireless link. One of the communications device and the fob is configured to transmit a request via a second wireless link different than the first wireless link. The other one of the communications device and the fob is configured to transmit the command to the base station via the first wireless link in response to receiving the request via the second wireless link.

Remote control systems for vehicles

A system and method for remote activation of a device includes, in one embodiment, transmitting a command signal according to one of a first transmission protocol and a second transmission protocol, and selecting the first transmission protocol for use in transmitting the command signal when a selected command is of a first type, and selecting the second transmission protocol for use in transmitting the command signal when a selected command is of a second.

System and method for one-way remote activation with adaptive protocol

A remote keyless entry system includes a portable communication device for communicating with an electronic control module of a transportation vehicle. The transmitter has at least two selectable communication channels for broadcasting communications signals to the transportation vehicle. A vehicle based electronic control module communicates with the portable communication device. The electronic control module includes a receiver that includes at least two selectable communication channels for receiving RF signals from the portable communication device. A controller selectively energizes the receiver for measuring a RSSI voltage level of each selectable communication channel of the receiver over respective predetermined time periods. The controller determines which of the at least two selectable communication channels includes a lowest noise level based on the measured RSSI voltage level. A channel status update signal is broadcast from the electronic control module to the portable communication device identifying the selected communication channel having the lowest noise level.

Keyless entry multi-channel RKE system

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.

System and method for two-way remote activation with adaptive protocol

A location system for use in locating a vehicle or other object. The system may include displaying directional information on a mobile device, such as but not limited to a mobile phone, personal digital assistant (PDA), remote vehicle control device (fob, RKE, passive entry, etc.). The displayed directional information may indicate a direction of travel to the vehicle without requiring the mobile device to rely on GPS satellites to determine a position useful in orientating the user in a direction toward the vehicle.

Method and system of locating stationary vehicle with remote device

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.

Multiple-channel receiver system and method

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.

System and method for remote activation with interleaved modulation protocol

A remote keyless entry system is provided comprising a handheld remote keyless entry transmitter in selectable wireless communication with a car based entry system. The handheld remote keyless entry transmitter comprises an integrated electronic compass element and logic adapted to store a first compass direction when activated and directed towards a destination. The logic further is adapted to display a return compass direction and a return distance from the car based entry system when activated leaving the destination.

Compass based car locator

A self-tuning duplicating transceiver is provided. The transceiver includes a microprocessor, a transmitter and a receiver. The transmitter includes an electrically tunable radio frequency oscillator, and the receiver includes a counter for determining an edge count associated with a received signal. The microprocessor is programmed to receive an unknown signal with the receiver and use the counter to determine the edge count thereof, and electrically tune the transmitter oscillator to a carrier frequency corresponding to the edge count for the unknown signal.

Self-tuning transmitter

A method and system for walk-away locking of a vehicle. The vehicle may be automatically locked when an occupant walks away from the vehicle in a passive manner. The automatic locking capabilities may be incorporated within an energy conservation strategy that allows one or more vehicle components and a fob to enter a sleep mode or otherwise become inactive at particular intervals when signals necessary to automatically locking the vehicle are less likely.

Automatic walk-away detection

A system and method for remote activation of a device includes, in one embodiment, a user interface for selecting a command associated with the one or more vehicle functions, a controller for processing the selected command, the controller having a plurality of input ports, and a switch array including a plurality of switches corresponding to the one or more vehicle functions. The plurality of switches can be divided into a first set and a second set with the first set of switches being connected across a fixed voltage and a controller input port and the second set of switches being connected across multiple controller input ports. The at least one of the controller input ports connecting the second set of switches may be temporarily configurable to an output port for determining which of the plurality of switches has been actuated.

System and method for remote activation using a transmitter switch array

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.
