摘要:
A vehicle has a reference receiver installed at an outer edge position of a desired detection area in a compartment to receive a signal transmitted from a transmitter in the compartment. The level of signal transmission output of the transmitter is adjusted based on the reception result of the reference receiver. It becomes possible to adjust the signal transmission output of the transmitter in the compartment so as to obtain a desired detection area at all times irrespective of change of the detection area reached by the request signal from the transmitter determined by the compartment or irrespective of variation in the electromagnetic wave environment in which the vehicle is placed.

A portable unit locating system is incorporated in a vehicle equipment control system including a portable unit and an in-vehicle unit, which communicate each other for controlling vehicle equipment such as doors. The in-vehicle unit includes inside transmitters, a receiver, a comparison ECU and a display. The transmitters transmit respective request signals in a vehicle compartment. The comparison ECU determines whether any response signal has been received from the portable unit in response the request signals, while gradually varying output levels of the request signals. The comparison ECU then specifies a location of the portable unit based on a change in determination results. The display visually or audibly notifies the specified location of the portable unit to a vehicle user.
摘要:
A vehicle approach warning apparatus for abnormality detection in various abnormal modes is provided. In the vehicle approach warning apparatus, a sound generator output from the microcomputer passes an AMP and HPF, and an output voltage corresponding to the sound generator output is applied to a speaker to emit vehicle approach sound. The vehicle approach warning apparatus includes a voltage sensor circuit and outputs a check usage output as the sound generator output at the abnormality detection. A single frequency output that is within a resonance frequency band of the speaker and that can be poorly reproduced by the speaker is used as the check usage output. The abnormality detection is performed based on whether an integration circuit voltage outputted from the voltage sensor circuit is within a voltage range being an abnormality determination threshold.

A control unit generates an annunciation sound signal including multiple frequency components. A sound emission device emits an annunciation sound to an outside of a vehicle according to the annunciation sound signal. The control unit changes a pitch of the annunciation sound signal according to a vehicle speed and changes an output level of the annunciation sound signal according to the pitch of the annunciation sound signal.

摘要:
In a rain shelter control system for vehicular doorways, an electronic key ECU causes exterior signal transmitters to periodically transmit request signals. When a portable device receives the request signal in an arrival range of the request signals, the portable device generates a response signal responsive to the request signal. When a receiver receives the response signal from the portable device, the electronic key ECU operates to automatically open any of rain shelters near the portable device, so that a holder of the portable device and passengers fold their umbrellas under the opened rain shelters, so that they can get into a vehicle without being exposed to rain. Besides, the electronic key ECU operates to automatically open the rain shelter when they get off the vehicle.
