摘要:
A tire pressure monitoring system may adjust the power it consumes. In at least one embodiment, the system includes a receiver that receives a first signal having a signal strength, determines the signal strength, and causes a second signal to be sent if the signal strength is more than a desired signal strength.

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.
摘要:
A universal monitor to be mounted in a tire of a vehicle, the monitor for use in a remote tire pressure monitoring system for the vehicle. The monitor includes a sensor for sensing tire pressure, and a storage device for storing a plurality of codes, each code comprising at least a data format. The monitor also includes a transmitter in communication with the sensor and the storage device, the transmitter for transmitting a wireless signal including data representing the sensed tire pressure. The wireless signal is transmitted by the transmitter according to at least one of the stored plurality of codes.

An automotive fob system may include an automotive fob and a fob charging receptacle. The automotive fob may have a loop feature, and include a power storage unit and a first inductive coil electrically connected with the power storage unit. The first coil may form a loop and be disposed in the loop feature. The fob charging receptacle may include a magnetic core configured to be inserted into the loop feature, and a second inductive coil wrapped around the core. The second inductive coil may be adapted to receive electrical current from a remote power source if electrically connected with the remote power source.
摘要:
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. A determination is made that the interrogation signal is an authorized interrogation signal in response to the determination that the interrogation signal includes the first pulse transmitted at the first amplitude following by the second pulse transmitted at the second amplitude where the second amplitude is greater than the first amplitude by at least a predetermined difference threshold.
摘要:
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.
