Abstract: When a demodulated signal of a radio signal in Ch1 transmitted from a TPMS transmitter is acquired, a control IC controls the frequency of a signal inputted from a PLL circuit to a mixer into a frequency for converting a TPMS radio signal into an intermediate frequency signal of a specific frequency. When the demodulated signal of the radio signal transmitted from a portable unit through two frequency channels is acquired, the control IC determines a channel whose state of communication is favorable from between Ch2 and Ch3, and controls the signal frequency for conversion into a frequency for converting a keyless radio signal in the determined channel into an intermediate frequency signal.

Abstract: When a vehicle door locking operation is conducted, an in-vehicle device checks the vehicle compartment to determine whether a mobile unit exists in the vehicle compartment. When the in-vehicle device receives a response from the mobile unit indicating its presence in the compartment, the in-vehicle device receives a response from the mobile unit, prohibits the door from locking, and activates a buzzer. The mobile unit thus can be prevented from being locked in the vehicle compartment. When the mobile unit receives the search signal, it sounds its buzzer, thereby making it possible to further indicate its location within the compartment.

The second fuel vapor adsorption device can adsorb a part of fuel vapor that still remains in a gas after desorption by the first fuel vapor adsorption device. The second fuel vapor adsorption device includes a first passage containing a fuel vapor adsorption material and a second passage containing no fuel vapor adsorption material. The first passage and the second passage allow the gas to flow therethrough. A gas introduction device allows the fuel vapor to flow from the second passage into the first passage.

Abstract: In a wireless communication system, a portable device transmits a first signal spread based on a reference period indicated by a synchronization signal transmitted from an in-vehicle device and transmits a second signal spread based on an operation by a user. The in-vehicle device sets a search period based on a variation range in a delay time from when the synchronization signal is transmitted to when the spread first signal is transmitted and sets a residual period that starts at an ending point of the search period and ends at an ending point of the reference period when a starting point of the reference period is set at a starting point of the search period. When the in-vehicle device fails in a synchronous acquisition for the search period, the in-vehicle device performs a synchronous acquisition process for the residual period.

Abstract: A vehicular combined control system has functions of a smart entry system and a TPMS. A smart ECU turns on the output of a voltage signal terminal intermittently or in response to a given trigger. When the output of the voltage signal terminal turns on, a RF receiver section receives information from a portable device regardless of the ON/OFF state of an ignition switch to transmit the information to the smart ECU. When the ignition switch is ON and the output of the voltage signal terminal turns off, the RF receiver section receives information from tire sensors to transmit the information to a TPMS microcomputer.

Abstract: A vehicle communication system has a receiving unit on a vehicle side for inputting a demodulated analog signal to determination units based on a received radio signal from a key unit. Then, one of the two determination units outputs a high-check signal that takes a high value when the analog signal is greater than a high threshold and the other determination unit outputs a low-check signal that takes a low value when the analog signal is smaller than a low threshold. Then, a sync. signal generator successively defines a determination period based on the high and low check signals. Then, a binary level of the analog signal is determined by a level determination unit based on the check signals, along with an estimation and a correction of an indefinite signal when the signal level cannot be determined based on a coding rule and the determination by the determination units.
