Abstract: An apparatus and method is provided for identifying unauthorized access to a vehicle having a keyless-passive entry system. An interrogation signal is broadcast from a vehicle based transmission device. The interrogation signal includes a first pulse transmitted at a first amplitude and a second pulse transmitted at a second amplitude where the second amplitude is greater than the first amplitude by at least a predetermined difference threshold. The interrogation signal is received by a portable communication device. A determination is made whether the second amplitude of the second pulse is greater than the first amplitude of the first pulse by a predetermined difference threshold.

Abstract: A remote unit for a keyless entry system for a vehicle. The remote unit comprising a controller configured to generate a command signal in response to a user input. The command signal comprising a first command message and a substantially similar second command message. The first command message comprises a first low data rate portion and the second command message comprises a high data rate portion. The remote unit further comprising a transmitter configured to transmit the command.

Abstract: A remote control system and a method of control. The system includes a control module that facilitates execution of a set of functions, a remote control device that wirelessly communicates with the control module, and an input signal. The input signal is provided to the control module and includes data that is associated with ambient lighting. Polling of the remote control device by the control module is deactivated for a subset of the set of functions when the data is indicative of sufficient ambient lighting.

Abstract: The disclosed embodiments include a wireless access system and method that enable the transmission of wireless access signals having a desired power level. In some embodiments, the wireless access system determines the amount of supply current drawn by certain devices and causes adjustment of the wireless access signal power level based on an assessment of the supply current.

Abstract: A method is provided for self-aligning a transmitting frequency between a portable transceiving device and a base station transceiving device. A test signal is transmitted from one of a portable or base station transceiving devices to the other of the portable or base station transceiving devices. The test signal has a frequency that varies during the transmission. The varying of the frequency of the test signal generates a plurality of discrete signals. The other of the portable or base station transceiving devices measures a RSSI value of each discrete signal. The other of the portable or base station transceiving devices determines a discrete signal having a maximum RSSI value. At least a portion of a subsequent message from the other of the portable transceiving device or the base station transceiving device is transmitted at an optimum frequency used for the test signal identified by the test result signal.
