Abstract: A forced-ventilation device ventilates a compartment of a vehicle by forced ventilation by actuating a blower of an air-conditioning device of the vehicle when the compartment is left at a high temperature. When a mode for forced ventilation has been set by the user, when a mobile device approaching the vehicle together with a user enters a predetermined detection area within which the mobile device is detectable by a response signal, and when the response signal is successfully verified, a control portion switches ON an ignition switch of the vehicle, opens one or two or more windows using an opening and closing mechanism, and directs the air-conditioning device to actuate the blower.

Abstract: In an antenna, a first element is connected to a GND of a feeder, on the same plane as a GND of a wireless circuit, and isolated from the GND of the wireless circuit. A second element is on the same plane as the GND of the wireless circuit and a first end connected to the first element and a second end as an open end. The third element has a first end connected to a power source of the feeder and located in a region occupied by the first element perpendicularly to the first element so that its first end source faces down. The fourth element has a first end connected to a second end of the third element and a second end as an open end, is parallel to the first element, and is perpendicular to a line connecting the first and second ends of the second element.

Abstract: An in-vehicle apparatus operates on a second frequency by a second vibrator while wirelessly receiving from a portable apparatus a wireless signal on a first frequency by a first vibrator along with information on temperature of the portable apparatus. The in-vehicle apparatus previously stores a data map of a frequency and temperature characteristic of the first vibrator and second vibrator while measuring own temperature. The in-vehicle apparatus has an amendment device that acquires an offset value for the second vibrator based on the data map and information on temperatures of the in-vehicle apparatus and portable terminal. The acquired offset value is added to the second vibrator to thereby cause the second frequency to approach the first frequency of the first vibrator.

Abstract: An in-vehicle device wirelessly sends a request signal to an assistance-possible area in which a user of a welfare-use seat device can be assisted. When a wireless portable key device, i.e., a remote control is present inside of the assistance-possible area, the portable key device returns a response signal containing an ID code. When receiving the response signal, the in-vehicle device executes a collation relative to the ID code contained in the response signal. When the collation is successfully completed, a short-depression movement mode is designated. When a short-time manipulation or depression is once applied to an operation instruction switch of the wireless portable key device under the short-depression movement mode being designated, the movement of a welfare-use seat device is started toward a movement end position without need further continued manipulation or depression to the operation instruction switch.

Abstract: In a vehicle control system, a vehicle unit transmits a smart request signal through its LF transmitter. When a mobile unit receives the smart request signal through its LF receiver, it transmits a response signal through its RF transmitter. The vehicle unit, receiving this response signal though its RF receiver, performs smart control such as door unlocking. The mobile unit further transmits a presence notification signal different from the response signal through its RF transmitter, when a predetermined notification condition is satisfied. The vehicle unit notifies passengers of the vehicle of the presence of the mobile unit, when it receives this notification signal while the predetermined condition is not satisfied.
