Abstract

A vehicular remote control apparatus warns a driver when the driver moves from the inside of a vehicle to the outside of the vehicle while an engine is operating. The vehicular remote control apparatus is located inside the vehicle and includes a transmitter-receiver for generating a first request signal and a portable device for generating a transmission signal in response to the first request signal and transmitting the transmission signal to the transmitter-receiver. The first request signal is transmitted to outside the vehicle. The transmitter-receiver includes a determining device for determining whether the engine is operating and a warning signal transmission device for generating a first warning signal if the engine is operating when receiving the transmission signal and transmitting the first warning signal to the portable device located outside the vehicle. The portable device includes a warning device for giving a warning when the portable device receives the first warning signal.
