Abstract
An in-vehicle system has a first transmitting antenna that is disposed in a substantial center in a front portion inside a vehicle, a second transmitting antenna that is disposed in the substantial center in a rear portion inside the vehicle, a third transmitting antenna that is disposed in a side surface near a driver seat or a passenger seat of the vehicle, a transmission controller that controls transmission of a first signal or a second signal from the first to third transmitting antennas, the second signal disturbing reception of the first signal, and a receiving antenna that receives a response signal, the response signal being transmitted from a portable device receiving the first signal transmitted from the first to third transmitting antennas.
Claims17
An in-vehicle system comprising:
- a first transmitting antenna that is disposed in a substantial center in a front portion inside a vehicle;
- a second transmitting antenna that is disposed in the substantial center in a rear portion inside the vehicle;
- a third transmitting antenna that is disposed in a side surface near a driver seat or a passenger seat of the vehicle;
- a transmission controller that controls transmission of a first signal or a second signal from the first to third transmitting antennas, the second signal disturbing reception of the first signal;
- a receiving antenna that receives a response signal, the response signal being transmitted from a portable device receiving the first signal transmitted from the first to third transmitting antennas;
- and
- a position detector that detects a position of the portable device based on a transmission content of the signal from the first to third transmitting antennas and a reception result of the response signal from the portable device.
An in-vehicle system comprising:
- a first transmitting antenna that is disposed in a substantial center in a front portion inside a vehicle;
- a second transmitting antenna that is disposed in the substantial center in a rear portion inside the vehicle;
- a third transmitting antenna that is disposed in a side surface near a driver seat or a passenger seat of the vehicle;
- a transmission controller that controls transmission of a signal from the first to third transmitting antennas, and controls existence or non-existence of transmission of a first signal or a second signal from the first to third transmitting antennas and a transmission pattern that is a pattern of a transmission intensity, the second signal disturbing reception of the first signal;
- a receiving antenna that receives a response signal, the response signal being transmitted from a portable device receiving the first signal transmitted from the first to third transmitting antennas;
- and
- a vehicle controller that controls the vehicle based on a reception result of the response signal from the portable device in each transmission pattern when at least two transmission patterns are combined.
An in-vehicle system that detects a position of a portable device based on a reception result of a response signal from the portable device with respect to a signal transmitted from a transmitting antenna, the in-vehicle system comprising:
- a first transmitting antenna that is disposed in a substantial center in a front portion inside a vehicle;
- a second transmitting antenna that is disposed in the substantial center in a rear portion inside the vehicle;
- a third transmitting antenna that is disposed in a side surface near a driver seat or a passenger seat of the vehicle;
- a receiving antenna that receives the response signal, the response signal being transmitted from the portable device receiving a predetermined signal transmitted from the first to third transmitting antennas;
- and
- a controller that controls transmission and reception of the signal at the first to third transmitting antennas and the receiving antenna.
