摘要： A keyless ignition system for a vehicle includes an electronic control unit (ECU) that communicates through a wireless link with a start/stop button. The start/stop button includes a plurality of lighting sources to selectively illuminate the start/stop button for communicating current state of a vehicle operating parameter. The lighting sources are powered by a wireless power generating device within the start/stop button.

摘要： An immobilizer system begins authentication of an identification device in response to an external triggering event. The external triggering event occurs prior to engagement with a reader module within the vehicle. Authorization commences prior to engagement to the reader module and continues after engagement with the reader module to reduce perceived authentication wait time.

摘要： A real time clock assembly includes paired crystal oscillators that experience changes in frequency responsive to temperature. The differences in frequency changes between the paired crystal oscillators are utilized to determine a temperature utilized to compensate for those shifts in frequency. The predictability of frequency responsive to temperature variations by the paired crystal oscillators is utilized for the determination of temperature.

摘要： A system for monitoring conditions within a tire (12) including a sensor assembly (14) including a pressure sensor (36), an accelerometer (34), a temperature sensor (32), and a transmitter (40) to transmit signals indicative of current tire conditions. A remote transmitter (22) for actuating a remote keyless entry system (19) emits a signal to actuate a function of the keyless entry system (19) such as unlocking doors (20) of the motor vehicle (10). A receiver assembly (16) includes an amplitude shift keyed receiver (52) and a frequency shift keyed receiver (58) selectively engagable to receive radio frequency transmissions from the tire monitoring system or the remote keyless entry system (19).

摘要： An improved key fob and key combination allows the mechanical key to be removed from the key fob and given to a valet attendant. The key is provided with a mechanical latch which may be easily removed from the key fob. When the key is removed, secured areas on the vehicle are locked. Moreover, the vehicle has limited operation when the mechanical key is not received with the key fob. In a second feature of this invention, a locator function on the key fob provides an indication of an approximate direction to a vehicle in a parking area. The key fob relies upon RF transmissions from the vehicle to determine an approximate direction to the vehicle.

摘要： A receiver is utilized to receive signals from various systems within a vehicle such as tire pressure monitoring system (TPM) and a remote keyless entry system (RKE). During the on time, the receiver sequentially is open to receive a first signal with a first baud rate. If the signal of the first baud rate is not received, the receiver receives a second signal at a second baud rate. Upon receipt of a transmission, the receiver operates according to a mode that corresponds to the transmission indicated by the specific baud rate. The operation of the receiver can include specialized filtering, or other known signal processing that is tailored to the specific transmission data communication requirements.

摘要： A method of localizing the location of a received signal from a tire pressure sensor includes sending an AM identification signal. The AM signal is adjusted for speed such that the frequency of the signal equals a constant multiplied by the speed of the vehicle. Each of the tire locations on a vehicle have an expected sequence of black-out points in the signal received by a receiver at any point on the vehicle. That is, given a particular vehicle design, the AM signal described above would be received at a receiver with an expected sequence of received peaks and black-out points. Since the frequency of the signal is adjusted for speed, the received signal will accurately allow the location of black-out points to be utilized to identify the tire location for a particular signal.

摘要： A combined battery holder and antenna is utilized into a remote signaling device, or keyfob for a vehicle. The battery holder receives the battery at an inner peripheral surface of a bobbin body. The coil antenna is wound about the outer peripheral surface of the bobbin body. In this way, the single part can provide both functions. This reduces the required space necessary for providing all functions within the keyfob.

摘要： The present invention includes a method of monitoring and controlling interior functions of a vehicle, for example, a memory seat position, a vehicle pedal position, a steering column position, a vehicle interior temperature, and/or whether the vehicle is occupied or unoccupied at certain times and under certain conditions. The interior functions are controlled by passively monitoring a characteristic of an occupant, determining an identity of the occupant based on the monitored characteristic, and regulating the interior function based upon the identity of the occupant. The monitored characteristic, for example, may be representative of a weight classification or biomass associated with the occupant, or a signal or input generated based upon a user identification device, for example, a key fob or other personal electronic device carried by the occupant.
