Rain shelter control system and method for doorway
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.
1. A rain shelter control system for a vehicle having a plurality of doorways comprising:
a rain shelter disposed at each doorway of a vehicle to be opened and closed;
a driver unit for opening and closing the rain shelter;
a rain sensor for detecting rain;
an exterior signal transmitter provided for each doorway for periodically transmitting a request signal toward outside of the vehicle;
a portable device held by a passenger of the vehicle and including a receiver unit for receiving the request signal, and a transmitter unit for transmitting a response signal outside automatically in response to the request signal;
a receiver for receiving the response signal transmitted from the portable device; and
a rain shelter opening/closing control unit for controlling the driver unit to open the rain shelter when the receiver receives the response signal and the rain sensor detects the rain,
wherein the rain shelter opening/closing control unit is configured to determine the rain shelter to be opened by the drive unit based on to which exterior signal transmitter the portable device has responded.
2. The rain shelter control system as in claim 1 , wherein the rain shelter opening/closing control unit controls the driver unit to automatically close the rain shelter after opening the rain shelter.
3. The rain shelter control system as in claim 2 , wherein the rain shelter opening/closing control unit controls the driver unit to maintain opening of the rain shelter as long as the receiver receives the response signal from the portable device after opening of the rain shelter.
4. The rain shelter control system as in claim 2 , wherein the rain shelter opening/closing control unit controls the driver unit to close the rain shelter when a predetermined time period elapses after opening of the rain shelter.
5. The rain shelter control system as in claim 2 , further comprising:
an interior signal transmitter for generating a request signal inside a vehicular compartment of the vehicle,
wherein the rain shelter opening/closing control unit controls the driver unit to close the rain shelter when the receiver receives the response signal transmitted from the portable device in response to the request signal of the interior signal transmitter.
6. The rain shelter control system as in claim 1 , wherein:
the rain shelter opening/closing control unit includes a setting unit for setting which rain shelter is to be opened.
7. The rain shelter control system as in claim 1 , wherein the rain shelter opening/closing control unit includes an indicator unit for indicating closing operation of the rain shelter.
