An in-vehicle device controller includes: an in-vehicle unit for controlling an in-vehicle device; and a portable device. The in-vehicle unit includes a request signal transmitter for transmitting a request signal including random information to the portable device. The portable device transmits a response signal in response to the request signal at multiple frequencies according to a switching pattern corresponding to a part of the random information. The in-vehicle unit further includes: a frequency specifying device for specifying the switching pattern based on the part of the random information; and a reception determination device for executing a reception determination process of the response signal based on a specified switching pattern. The in-vehicle device identifies the portable device according to the reception determination process, and controls the in-vehicle device according to an identification of the portable device.

A vehicle receiver system includes: a receiver provided in a vehicle cabin, wherein an operating mode of the receiver includes a first mode for receiving a first wireless signal transmitted from a portable key, and a second mode for receiving a second wireless signal relating to a tire air pressure, transmitted from a transmitter provided on a tire; and a key verification device that performs key verification on the portable key in the vehicle cabin on the basis of the first wireless signal. In a predetermined situation, the receiver is configured such that the operating mode of the receiver is switched between the first mode and the second mode, and proportion of a second mode operation time in which the receiver operates in the second mode is set to be greater when a vehicle speed is relatively high than when the vehicle speed is relatively low.

A mobile device includes a transmitting unit that, each time an ON operation of a switch in a first mode is performed, transmits a wireless signal corresponding to the first mode ON operation by changing a frequency band among three or more frequency bands and that, when an ON operation of the switch in a second mode is performed, transmits a wireless signal, corresponding to the second mode ON operation, in the frequency band selected at that time. The transmitting unit includes a frequency band computing unit that selects one of the three or more frequency bands through a computation for changing a communication environment when the second mode ON operation of the switch is repeatedly performed. A receiver of the in-vehicle device receives a wireless signal transmitted from the transmitting unit and recognizes command information allocated in advance in correspondence with each ON operation mode of the switch.

In an in-vehicle device control system, an in-vehicle device is controlled based on a checkup result of checkup operation, in which a checkup about a portable device is performed by mutual communication of transmitting a request signal from a vehicle-side unit mounted on a vehicle and transmitting in return a response signal from the portable device in response to the request signal. If the checkup is unsuccessful, the mutual communication is performed again by switching the communication frequency to perform the checkup again. When a user operates a door lock sensor, the vehicle-side unit performs an exterior checkup first. If the checkup is successful, a communication frequency, by which the checkup was performed successfully, is stored in a memory. The vehicle-side unit sets the communication frequency stored in the memory as a communication frequency, which is to be designated to the portable device, for performing an interior checkup next time.

A frequency switching terminal is provided to input a signal for switching frequencies of a reception circuit. A smart ECU is connected to the frequency switching terminal via a connection cable. When the signal for switching the frequencies is inputted into an external input terminal of the reception circuit from the smart ECU via the frequency switching terminal, the reception circuit receives a first electric wave transmitted from a portable terminal for smart entry. In contrast, when the signal for switching the frequencies is not inputted into the external input terminal of the reception circuit from the smart ECU via the frequency switching terminal, the reception circuit receives a second electric wave transmitted from a tire sensor.
