ELECTRONIC DEVICE, CONTROL METHOD FOR ELECTRONIC DEVICE, AND CONTROL PROGRAM FOR ELECTRONIC DEVICE
First Claim
1. An electronic device comprising:
- a monitor unit configured to monitor a traveling speed and a traveling position of a host car, and a speed and a position of a preceding car, the host car being a vehicle in which the electronic device is mounted, the preceding car being a vehicle traveling ahead of the host car;
a reception unit configured to receive traffic signal information including at least a current display state of a traffic light located ahead of the host car in a traveling direction thereof and information on a timing when the display of the traffic light is changed;
a prediction unit configured to generate a first prediction result of a prediction whether or not the preceding car will go into the intersection where the traffic light changes to a red signal display state when the preceding car maintains a current speed thereof based on monitor information and the traffic signal information received by the reception unit, and generate a second prediction result of a prediction whether or not the preceding car can stop before the intersection where the traffic light becomes the red signal display state without braking suddenly based on the position and the speed of the preceding car and a distance between the preceding car and the intersection, the monitor information including the traveling speed and the traveling position of the host car and the speed and the position of the preceding car monitored by the monitor unit; and
a warning unit configured to give a first-stage warning when the first prediction result indicates that the preceding car will go into the intersection where the traffic light changes to the red signal display state, and give a second-stage warning when the second prediction result indicates that the preceding car cannot stop before the intersection where the traffic light is in the red signal display state without braking suddenly.

Abstract
An electronic device includes: a monitor unit configured to monitor a speed and a position of a host car and a preceding car; a reception unit configured to receive traffic signal information including at least a current display state of a traffic light and information on a timing when the display of the traffic light is changed; a prediction unit configured to generate a first prediction result and a second prediction result; and a warning unit configured to give a first-stage warning when the first prediction result indicates that the preceding car will go into the intersection where the traffic light changes to the red signal display state, and give a second-stage warning when the second prediction result indicates that the preceding car cannot stop before the intersection where the traffic light is in the red signal display state without braking suddenly.

4. A control method for an electronic device comprising:
-
a monitoring step for monitoring a traveling speed and a traveling position of a host car, and a speed and a position of a preceding car, the preceding car being a vehicle traveling ahead of the host car; a receiving step for receiving traffic signal information including at least a current display state of a traffic light located ahead of the host car in a traveling direction thereof and information on a timing when the display of the traffic light is changed; a predicting step for generating a first prediction result of a prediction whether or not the preceding car will go into the intersection where the traffic light changes to a red signal display state when the preceding car maintains a current speed thereof based on monitor information and the traffic signal information received in the receiving step, and generating a second prediction result of a prediction whether or not the preceding car can stop before the intersection where the traffic light becomes the red signal display state without braking suddenly based on the position and the speed of the preceding car and a distance between the preceding car and the intersection, the monitor information including the traveling speed and the traveling position of the host car and the speed and the position of the preceding car monitored in the monitoring step; and a warning step for giving a first-stage warning when the first prediction result indicates that the preceding car will go into the intersection where the traffic light changes to the red signal display state, and giving a second-stage warning when the second prediction result indicates that the preceding car cannot stop before the intersection where the traffic light is in the red signal display state without braking suddenly.

5. A control program for an electronic device for causing a computer to execute:
-
a monitoring step for monitoring a traveling speed and a traveling position of a host car, and a speed and a position of a preceding car, the preceding car being a vehicle traveling ahead of the host car; a receiving step for receiving traffic signal information including at least a current display state of a traffic light located ahead of the host car in a traveling direction thereof and information on a timing when the display of the traffic light is changed; a predicting step for generating a first prediction result of a prediction whether or not the preceding car will go into the intersection where the traffic light changes to a red signal display state when the preceding car maintains a current speed thereof based on monitor information and the traffic signal information received in the receiving step, and generating a second prediction result of a prediction whether or not the preceding car can stop before the intersection where the traffic light becomes the red signal display state without braking suddenly based on the position and the speed of the preceding car and a distance between the preceding car and the intersection, the monitor information including the traveling speed and the traveling position of the host car and the speed and the position of the preceding car monitored in the monitoring step; and a warning step for giving a first-stage warning when the first prediction result indicates that the preceding car will go into the intersection where the traffic light changes to the red signal display state, and giving a second-stage warning when the second prediction result indicates that the preceding car cannot stop before the intersection where the traffic light is in the red signal display state without braking suddenly.
