Abstract
An electronic device comprises a controller that performs control to switch between a first mode and a second mode. In the first mode, the controller transmits first transmission waves from a plurality of transmission antennas installed in a mobile body. In the second mode, the controller transmits second transmission waves beamformed from the transmission antennas. The controller performs control to switch from the first mode to the second mode, when detecting a stop space for the mobile body.
Claims9
An electronic device comprising:
- a plurality of transmission antennas installed in a mobile body;
- and
- a controller configured to:
- switch between a first mode of transmitting first transmission waves from the transmission antennas and a second mode of transmitting second transmission waves beamformed from the transmission antennas;
- and
- perform control to cause a beam width of the transmission waves transmitted in the second mode to be narrower in azimuth than a beam width of the transmission waves transmitted in the first mode,
- wherein the controller is configured to switch from the first mode to the second mode, when a process for detecting a stop space for the mobile body has started,
- the controller is configured to perform control to switch between the first mode and the second mode, after switching to the second mode, and
- the controller is configured to perform control to cause an operation time in the first mode to be shorter than an operation time in the second mode, after switching to the second mode.
A control method of an electronic device, the control method comprising:
- transmitting first transmission waves from a plurality of transmission antennas installed in a mobile body;
- transmitting second transmission waves beamformed from the transmission antennas;
- performing control to cause a beam width of the second transmission waves to be narrower in azimuth than a beam width of the first transmission waves;
- performing control to switch from the transmitting of the first transmission waves to the transmitting of the second transmission waves, when a process for detecting a stop space for the mobile body has started,
- wherein the method comprises performing control to switch between the transmitting of the first transmission waves and the transmitting of the second transmission waves, after switching to the transmitting of the second transmission waves, and
- the method comprises performing control to cause an operation time of the transmitting of the first transmission waves to be shorter than an operation time of the transmitting of the second transmission waves, after switching to the transmitting of the second transmission waves.
A non-transitory computer-readable recording medium storing computer program instructions, which when executed by an electronic device, cause a computer to:
- transmit first transmission waves from a plurality of transmission antennas installed in a mobile body;
- transmit second transmission waves beamformed from the transmission antennas;
- performing control to cause a beam width of the second transmission waves to be narrower in azimuth than a beam width of the first transmission waves;
- and
- perform control to switch from the transmitting of the first transmission waves to the transmitting of the second transmission waves, when a process for detecting a stop space for the mobile body has started,
- wherein the instructions cause the computer to perform control to switch between the transmitting of the first transmission waves and the transmitting of the second transmission waves, after switching to the transmitting of the second transmission waves, and
- the instructions cause the computer to perform control to cause an operation time of the transmitting of the first transmission waves to be shorter than an operation time of the transmitting of the second transmission waves, after switching to the transmitting of the second transmission waves.
