摘要:
A capacitance touch sensing device that detects the touch of a user against a surface of a door handle on the outside of a vehicle includes an upper sensor electrode provided in an upper portion of the door handle, a lower sensor electrode provided in a lower portion of the door handle, an upper detecting portion that detects when the user has touched an upper surface of the door handle based on output from the upper sensor electrode, and a lower detecting portion that detects when the user has touched a lower surface of the door handle based on output from the lower sensor electrode. The detection sensitivity of one of the upper detecting portion or the lower detecting portion is lower than the detection sensitivity of the other.

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.

A remote control system includes a mobile device and a receiver connected to a control target. The mobile device includes an input unit accepting user's input operation; an operation signal transmission unit wirelessly transmitting an operation signal corresponding to the input operation during the input operation; a frequency switching determination unit determining whether to switch the transmission frequency band from a first frequency band to a second frequency band based on at least any one of a manner of the input operation and a state of wireless communication; and a transmission frequency switching unit switching the transmission frequency band when the frequency switching determination unit determines to switch the transmission frequency band. The receiver includes an operation signal reception unit receiving the operation signal; and a control unit controlling the control target on the basis of the received operation signal.

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.

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 wireless communication method is provided. This method includes: selecting one of a plurality of predetermined frequency bands each time a switch operation is manually performed in a transmitter, and then using the selected frequency band to transmit a radio signal corresponding to the switch operation for a predetermined specified transmission time; in a receiver apparatus, receiving the transmitted wireless signal, and then recognizing the content of a command that has already been assigned in accordance with the switch operation; and defining an intermittent reception standby period, which is repeated at a predetermined cycle for each of the frequency bands.

A receiver (200) that receives a radio signal transmitted from a transmitter includes a receiving unit (2042) that receives a signal that is wirelessly transmitted from the transmitter at one of a plurality of transmission frequencies, a receiving frequency change determining unit (2048) that determines whether a receiving frequency is to be changed, based on the signal received by the receiving unit, and a communication error acceptance time setting unit (2046) that sets an acceptance time as a period of time for which communication errors after confirmation of a receiving operation are accepted, based on the signal received by the receiving unit. The communication error acceptance time setting unit sets the acceptance time to different periods of time, depending on whether the receiving frequency change determining unit determines that the receiving frequency is to be changed.
