Vehicle remote control apparatus and vehicle remote control system using the same
First Claim
1. A vehicle remote control apparatus comprising:
- a first transmitter with a first function outputting an authentication request signal to a mobile device, the mobile device including a radio terminal assigned with an identification code special to a vehicle and outputting an authentication response signal corresponding to the identification code;
a second transmitter with a second function of outputting an interference wave canceling the authentication request signal at the same time as the first transmitter transmits the authentication request signal;
a receiver for receiving the authentication response signal output from the mobile device in response to the authentication request signal, thereby checking authenticity of the authentication response signal;
a controller for controlling operation of an on-vehicle equipment unit based on a result of authentication of the authentication response signal; and
wherein the first transmitter and the second transmitter exchange the first function and the second function when the receiver does not receive an authentication response signal for a predetermined period of time.
