Abstract
A vehicle remote controller that reduces the number of parts. The vehicle remote controller includes a portable device carried by a driver and a transceiver (11) arranged in the vehicle to output a request signal for intercommunicating with the portable device and to output a transponder driving radio wave. The transceiver outputs the request signal to either a first area, which is in a vehicle passenger compartment, or an area outside the vehicle, and has a common antenna (14) for outputting the transponder driving radio wave to a second area, which is in the vehicle passenger compartment.
Claims20
A vehicle remote controller comprising a portable device carried by a driver and a transceiver arranged in a vehicle having a vehicle passenger compartment to output a request signal for intercommunicating with the portable device and to output a transponder driving radio wave, wherein said transceiver has a common antenna for selectively transmitting the request signal and the transponder driving radio wave, and wherein the vehicle passenger compartment includes a first area where the request signal is output and a second area smaller than the first area where the transponder driving radio wave is output.
A vehicle remote controller comprising a transceiver arranged in a vehicle having a vehicle passenger compartment to generate a request signal and a transponder driving radio wave, and a portable device carried by a driver, the portable device having a request signal processing circuit for receiving the request signal from the transceiver, generating a first signal based on the request signal, and transmitting the first signal to the transceiver, and a transponder for receiving the transponder driving radio wave, which generates electric power, from the transceiver, generating a transponder signal based on the transponder driving radio wave, and transmitting the transponder signal to the transceiver, wherein said transceiver includes a common antenna for selectively transmitting the request signal and the transponder driving radio wave to the portable device, and wherein the vehicle passenger compartment includes a first area where the request signal is output and a second area smaller than the first area where the transponder driving radio wave is output.
A transceiver of a vehicle remote controller arranged in a vehicle having a vehicle passenger compartment to output a request signal, used to intercommunicate with a portable device carried by a driver, to one of inside a vehicle passenger compartment and outside the vehicle passenger compartment, and to output a transponder driving radio wave to the inside of the vehicle passenger compartment, wherein said transceiver comprises a common antenna for selectively transmitting the request signal and the transponder driving radio wave, and wherein the vehicle passenger compartment includes a first area where the request signal is output and a second area smaller than the first area where the transponder driving radio wave is output.
A vehicle remote controller comprising:
- a portable device carried by a driver;
- and
- a transceiver arranged in a vehicle having a vehicle passenger compartment to output a request signal for intercommunicating with the portable device and to output a transponder driving radio wave;
- wherein the vehicle passenger compartment includes a first area where the request signal is output and a second area smaller than the first area where the transponder driving radio wave is output.
A vehicle remote controller comprising:
- a transceiver arranged in a vehicle having a vehicle passenger compartment to generate a request signal and a transponder driving radio wave;
- and
- a portable device carried by a driver, the portable device having a request signal processing circuit for receiving the request signal from the transceiver, generating a first signal based on the request signal, and transmitting the first signal to the transceiver, and a transponder for receiving the transponder driving radio wave, which generates electric power, from the transceiver, generating a transponder signal based on the transponder driving radio wave, and transmitting the transponder signal to the transceiver;
- wherein the vehicle passenger compartment includes a first area where the request signal is output and a second area smaller than the first area where the transponder driving radio wave is output.
