Abstract
A vehicle remote-operation apparatus is provided which transmits a regular authentication request signal from a vehicle-outside antenna and simultaneously transmits an interference wave for negating this authentication request signal from a vehicle-inside antenna, so that the communicable range can be limited between a radio portable unit allocated an identification code unique to a vehicle and the vehicle-outside antenna. Thereby, authentication communication is established only for a regular communication request.
Claims13
A vehicle remote-operation apparatus, comprising:
- a radio portable unit which is allocated an identification code unique to a vehicle;
- a plurality of transmitters which output an authentication request signal to the portable unit;
- an authentication-signal receiver which receives an authentication response signal outputted from the portable unit in response to the authentication request signal;
- and
- a controller which controls a specific in-vehicle unit based on the authentication result of the authentication response signal, so that the in-vehicle unit is permitted to operate or prohibited from operating,
- wherein when the portable unit is inside of the vehicle, the controller controls the plurality of transmitters so that a transmitter outside of the vehicle among the plurality of transmitters transmits a regular authentication request signal and so that at least one or more transmitters inside of the vehicle transmit an interference wave for negating the authentication request signal, and limits the communicable range between the portable unit and the transmitters.
A vehicle remote-operation apparatus, comprising:
- a vehicle-side communication unit which is provided in a vehicle;
- and
- a portable unit which is allocated an identification code unique to a vehicle and communicates by radio with the vehicle-side communication unit, wherein:
- the vehicle-side communication unit includes,
- a vehicle-outside transmitter which transmits an authentication request signal for the portable unit to at least the outside of the vehicle,
- a vehicle-inside transmitter which transmits the authentication request signal to the inside of the vehicle,
- an authentication-signal receiver which receives an authentication response signal outputted from the portable unit in response to the authentication request signal, and
- a controller which controls a specific in-vehicle unit based on the authentication result of the authentication response signal, so that the in-vehicle unit is permitted to operate or prohibited from operating;
- and
- the controller transmits the authentication request signal using the vehicle-outside transmitter, and using the vehicle-inside transmitter, transmits, to the inside of the vehicle, an interference wave for disabling the inside of the vehicle from receiving the authentication request signal by the vehicle-outside transmitter.
A vehicle-side communication unit which is provided in a vehicle and communicates by radio with a portable unit allocated an identification code unique to the vehicle, comprising:
- a vehicle-outside transmitter which transmits an authentication request signal for the portable unit to at least the outside of the vehicle;
- a vehicle-inside transmitter which transmits the authentication request signal to the inside of the vehicle;
- an authentication-signal receiver which receives an authentication response signal outputted from the portable unit in response to the authentication request signal;
- and
- a controller which controls a specific in-vehicle unit based on the authentication result of the authentication response signal, so that the in-vehicle unit is permitted to operate or prohibited from operating,
- wherein the controller transmits the authentication request signal using the vehicle-outside transmitter, and using the vehicle-inside transmitter, transmits, to the inside of the vehicle, an interference wave for disabling the inside of the vehicle from receiving the authentication request signal by the vehicle-outside transmitter.
