Abstract

A mobile communication device is provided in a mobile object, and is capable of providing turn collision prevention support, so as to prevent a collision with another mobile object at a risk of collision when the mobile object turns. The mobile communication device includes: a communication unit for receiving information that includes information indicating a signal indication of a traffic signal; and a control unit for determining a notification mode to provide a predetermined notification to draw an attention via a notification unit when turning. The control unit determines the notification mode regardless of whether or not the another mobile object is present when the signal indication of the traffic signal for the traveling direction of the mobile object is an advance-prohibited signal indication with turning-permitted signal indication. Thus the device achieves smooth traffic and preventing excessive support through turn collision prevention support depending on a signal indication.

Claims

1. A mobile communication device, which is provided in a mobile object and capable of providing a turn collision prevention support to prevent a collision with another mobile object at a risk of collision when the mobile object turns, the mobile communication device comprising:

a communication unit for receiving information including information indicating a signal indication of a traffic signal; and

a control unit for determining a notification mode to provide a predetermined notification to draw an attention at a time of turning via a notification unit,

wherein when the signal indication of the traffic signal in a traveling direction of the mobile object is an advance-prohibited signal indication with turning-permitted signal indication, the control unit determines the notification mode regardless of whether or not the another mobile object is present.

2. A mobile communication device according to claim 1, wherein the control unit further determines whether or not the another mobile object is stoppable before colliding with the mobile object, and determines the notification mode regardless of whether or not the another mobile object is present only when the signal indication of the traffic signal in the traveling direction of the mobile object is the advance-prohibited signal indication with turning-permitted signal indication, and when it is determined that the another mobile object is stoppable before colliding with the mobile object.

3. A mobile communication device according to claim 1, wherein the another mobile object comprises a vehicle present in a sensing area.

4. A mobile communication device according to claim 1, wherein the traffic signal is ahead of the mobile object.

5. A mobile communication device according to claim 1, wherein when the signal indication of the traffic signal in the traveling direction of the mobile object is an advance-permitted signal indication or a stop signal indication, the control unit determines the notification mode based on presence of the another mobile object.

6. A mobile communication device according to claim 1, wherein when the signal indication of the traffic signal in the traveling direction of the mobile object is an advance-prohibited signal indication, the control unit determines the notification mode based on the signal indication of the traffic signal.

7. A traveling support method, comprising the steps of:

acquiring information including information indicating a signal indication of a traffic signal;

determining whether or not the signal indication of the traffic signal in a traveling direction of the mobile object is an advance-prohibited signal indication with turning-permitted signal indication;

determining a notification mode regardless of whether or not another mobile object is present when the signal indication of the traffic signal in the traveling direction of the mobile object is the advance-prohibited signal indication with turning-permitted signal indication; and

providing, via a notification unit, a predetermined notification to draw an attention at a time of turning based on the determined notification mode.
