An example base station assembly includes a transmitter configured to communicate a challenge signal and at least one timing signal to a plurality of fobs. The base station initiates a vehicle operation in response to at least one return signal. The return signal is communicated to the base station from at least one of the fobs in response to the timing signal.

Vehicle and fob communication arrangement

A passive entry and start system includes a controller that calculates the cryptology required for each remote identification device during idle transmission time to reduce overall system actuation time.

Cryptology calculation for remote entry devices

A disclosed example receiver for receiving transmissions and data for both a remote keyless entry (RKE) system and a tire pressure monitoring (TPM) system tailors the data slice level to the characteristics unique to each of the RKE transmissions and the TPM transmissions.

Adaptive switching receiver slice level

A receiver receives transmission containing information from different vehicle systems and determines an origin of that transmission according to the length of the transmission.

Multiple protocol reception and differentiation

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.

Passive control of vehicle interior features based upon occupant classification

An example receiver/transmitter for a passive start and entry system switches between amplitude shift keyed modulation and frequency shift keyed modulation to maintain clear uninterrupted and dependable communication with a remote transmitter in the presence of interfering signals. The receiver/transmitter is switched to receive incoming FSK signals in response to the RSSI becoming saturated by undesired signals. The switch to FSK signal modulation occurs by signaling the remote transmitter to change over and begin sending FSK modulated signals. The FSK modulated signals are then received without significant interference.

Transmitter modulation switching

A system for monitoring conditions within a tire includes a sensor assemblies (). The sensor assemblies () emit a transmission () containing information indicative of conditions within a tire to a receiver (). The transmission () from the sensor assemblies () includes an amplitude shift key wake up portion and various data packet portions. The data packet portions are separated by a variable interval to prevent collisions of transmissions at the receiver.
