Vehicular remote control apparatus and engine operation warning method

A remote control apparatus of a vehicle having an engine, the remote control apparatus comprising:

• a transmitter-receiver located inside the vehicle, wherein the transmitter-receiver generates a request signal, which includes a first ID code;
• and
• a portable device, wherein the portable device generates a transmission signal, which includes a second ID code corresponding to the first ID code, in response to the request signal and transmits the transmission signal to the transmitter-receiver,
• wherein the request signal is transmitted to outside the vehicle when the vehicle is stopped, and
• wherein the transmitter-receiver includes:
• a first control device, wherein the first control device determines whether the engine is operating and receives the transmission signal, wherein the first control device determines whether the first ID code coincides with the second ID code, and wherein, when it is determined that the engine is operating and the first ID code coincides with the second ID code, the first control device generates a first warning signal;
• and
• a transmission circuit connected to the first control device, wherein the transmission circuit transmits the first warning signal with the first ID code to outside the vehicle, and
• wherein the portable device includes:
• a second control device, wherein the second control device receives the first warning signal and determines whether the first ID code coincides with the second ID code, and wherein, when the first ID code coincides with the second ID code, the second control device generates a first warning control signal;
• and
• a warning device connected to the second control device, wherein the warning device gives a warning indicating that the engine is operating in accordance with the first warning control signal.

A method relating to a vehicle having an engine for giving a warning by means of a transmitter-receiver located inside the vehicle and a portable device that communicates with the transmitter-receiver, the method comprising:

• generating a first request signal including a first ID code and transmitting the first request signal to outside the vehicle by means of the transmitter-receiver when the vehicle is stopped,
• generating a transmission signal, which includes a second ID code corresponding to the first ID code, in response to the first request signal and transmitting the transmission signal to the transmitter-receiver;
• generating a first warning signal if the engine is operating when the transmitter-receiver receives the transmission signal;
• transmitting the first warning signal to outside the vehicle;
• and
• giving a first warning by means of the portable device in accordance with the first warning signal when the portable device receives the first warning signal, wherein the first warning indicates that the engine is operating.
