Abstract
A vehicle remote control system can have a transmitter transmitting a signal, a receiver receiving the signal, and a control device in communication with the receiver and controlling at least one operation of the vehicle. A selected operation may be executable by the signal. The vehicle remote control system includes a microphone that can determine an ambient noise volume and an ambient noise frequency in an area around the vehicle and is in communication with the control device. Furthermore, the vehicle remote control system includes a speaker that is able to generate an answer signal to confirm that the selected operation was executed. The speaker is in communication with the control device which generates an answer signal as a function of ambient noise volume and the ambient noise frequency in the area surrounding the vehicle.
