Driving state determining system
First Claim
1. A driving state determining system provided in a vehicle, the system comprising:
- an obtaining unit that obtains information including vehicle information of the vehicle and surrounding information for understanding a state surrounding the vehicle;
a determining unit that recognizes an obstruction that has a possibility of colliding with the vehicle based on the information and executes a plurality of danger determinations that have individual determination conditions, based on a relative distance between the vehicle and the obstruction and a relative speed between the vehicle and the obstruction; and
an outputting unit that outputs to other devices a signal based on a result of a danger determination executed by the determining unit.

Abstract
A driving state determining system in a vehicle recognizes an obstruction that may collide with the vehicle based on obtained various information. The system executes a plurality of danger determinations that have individual determination conditions, based on a relative distance and a relative speed with the obstruction to thereby comprehensively determine one of danger regions that the vehicle is situated in. The danger regions are classified depending on a danger degree. The system then outputs a determined result to relevant devices. Each of the relevant devices thereby determines operation by obtaining the comprehensively determined result outputted by the system. Consequently, the relevant devices can function more cooperatively and more effectively to lead to increase in safety than another system where each of relevant devices determines operation by individually collecting information.

11. A driving state determining system provided in a vehicle, the system comprising:
-
an obtaining unit that obtains information including vehicle information of the vehicle and surrounding information for understanding a state surrounding the vehicle;
a determining unit that recognizes a point where the vehicle needs to stop based on the information and executes a plurality of danger determinations that have individual determination conditions, based on a distance between the vehicle and the point and a speed of the vehicle; and
an outputting unit that outputs to other devices a signal based on a result of a danger determination executed by the determining unit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A driving state determining system provided in a vehicle, the system comprising:
-
an obtaining unit that obtains information including both vehicle information of the vehicle and surrounding information for understanding a state surrounding the vehicle;
a determining unit that recognizes, based on the information, a prevention-necessitating target that necessitates the vehicle to prevent danger relating to the prevention-necessitating target and executes a plurality of danger determinations that have individual determination conditions, based on a distance and a speed with respect to the prevention-necessitating target; and
an outputting unit that outputs to other devices a signal based on a result of a danger determination executed by the determining unit. - View Dependent Claims (22, 23)

24. A driving state determining method provided in a vehicle, the method comprising steps:
-
obtaining information including both vehicle information of the vehicle and surrounding information for understanding a state surrounding the vehicle;
recognizing, based on the information, a prevention-necessitating target that necessitates the vehicle to prevent danger relating to the prevention-necessitating target;
executing one of a plurality of danger determinations that have individual determination conditions, based on a distance and a speed with respect to the prevention-necessitating target; and
outputting to other devices a signal based on a result of the one of the plurality of danger determinations executed.
