Abstract: A system and method for decoding signals from a tire pressure monitoring (TPM) system and a remote keyless entry (RKE) system includes determining a signal strength of the signal. The method also includes evaluating at least a first bit and the signal strength of the signal. The method further includes determining a first bit threshold based on the evaluated first bit and the signal strength.

Abstract: A method is provided for selectively providing power to at least one component of a vehicle-based receiver module for determining the presence and validity of a transmitted RF signal. The RF signal is a request signal for activating a respective vehicle accessory function. Power is provided to a receiver for a first period of time. The receiver is operated to receive any RF signal that may be present from a remote transmitting device. A received signal strength indicator (RSSI) associated with operating the receiver is determined. A determination is made whether the RSSI is greater than a first predetermined threshold. The power is terminated to the receiver after the first period of time if the RSSI is not greater than the first predetermined threshold.

Abstract: A method and system are disclosed for operating a controller of and a RKE system to provide for short distance functions that are actuatable from a key fob at a shorter distance from the vehicle than other long distance functions. This may include receiving a desired type of radio frequency signal; actuating a high gain mode of a receiver of the controller; detecting a message from an acceptable remote keyless entry transmitter; decoding a function code portion of the message; changing the receiver from the high gain mode to a lower gain mode if the function code is not a long distance function; decoding a remaining portion of the message; determining if the remaining portion of the message was decoded properly; and performing the requested function if the remaining portion of the message was decoded properly.

Abstract: The present invention concerns a method for verifying a command in a vehicle remote communication system. The remote communication system includes a remote transmitter, and a vehicle body having a receiver module and a control module connected by a communication bus disposed therein. The control module is in communication with at least one vehicle system. The remote transmitter transmits an activation signal that is received and decoded by the receiver module. The receiver module transmits a first message along the communication bus that is received by the control module. The control module transmits an acknowledgment message that is received by the receiver module. The receiver module re-transmits the first message that is received by the control module. The control module then initializes a vehicle system command to the vehicle system, thereby preventing an inadvertent activation of the vehicle system.

Abstract: In a system for remote monitoring of tire pressure in a vehicle having front tires including a right tire and a left tire, and rear tires including a right tire and a left tire, a system and method are provided for automatically identifying tire location. A transmitters mounted in each tire transmits tire information signals conveying tire pressure data and associated tire rotation direction data. A vehicle mounted receiver has a location a first distance from the front tires and a second distance from the rear tires, the first distance being different from the second. A vehicle mounted controller in communication with the receiver determines whether pressure data is associated with a front tire or a rear tire based on the strength of the tire information signal, and whether pressure data is associated with a right tire or a left tire based on the associated rotation direction data.
