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.

What is claimed is: 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 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 wherein the obtaining unit obtains from map data the information as to whether a temporary-stop-required point is present in an area surrounding the vehicle, and the determining unit recognizes the point where the vehicle needs to stop when the temporary-stop-required point is determined to be present. 2. The driving state determining system of claim 1, further comprising: a communicating unit that communicates with an outside of the vehicle to obtain second information, wherein the determining unit recognizes the point additionally based on the second information. 3. The driving state determining system of claim 1, wherein one of the danger determination is whether the vehicle is in a state where attention of a driver of the vehicle needs to be drawn based on the distance and the speed. 4. The driving state determining system of claim 3, wherein, when the determining unit determines that the vehicle is in a state where attention of a driver of the vehicle needs to be drawn, the outputting unit outputs the signal that includes one of: a signal for notifying that attention of a driver needs to be drawn; a signal for causing a sound output device to output a warning sound; and a signal for causing a display device to output a warning display. 5. The driving state determining system of claim 1, wherein one of the danger determinations is whether the vehicle is in a state where a driver of the vehicle needs to start an operation for preventing danger based on the distance and the speed. 6. The driving state determining system of claim 5, wherein, when the determining unit determines that the vehicle is in a state where a driver of the vehicle needs to start an operation for preventing danger, the outputting unit outputs the signal that includes one of: a signal for notifying that a driver needs to start an operation for preventing danger; a signal for vibrating a steering wheel of the vehicle; a signal for vibrating a driver's seat; and a signal for fastening a seatbelt to cause the driver to recognize. 7. The driving state determining system of claim 1, wherein one of the danger determinations is whether the vehicl is in a state where an ordinary braking function in a driving operation of the vehicle will unavoidably disable the vehicle from stopping before reaching the point based on the distance and the speed. 8. The driving state determining system of claim 7, wherein, when the determining unit detennines that the vehicle is in a slate where an ordinary braking function unavoidably disables the vehicle from stopping before reaching the point, the outputting unit outputs the signal that includes one of. a signal for notifying a result determined by the determining unit; a signal for forcibly braking the vehicle; a signal for returning a driver's seat to a normal position; and a signal for fastening a seatbelt to fix the driver to the driver's seat. 9. The driving state determining system of claim 1, wherein the obtaining unit further obtains traffic regulation information relating to a traffic regulation of a road surrounding the vehicle, and wherein the determining unit executes the danger determinations additionally based on the traffic regulation information. 10. The driving state determining system of claim 1, further comprising: a communicating unit that communicates with a comparable second driving state determining system provided in a second vehicle, wherein the obtaining unit obtains, via the communicating unit, information obtained by a comparable second obtaining unit included in the second driving state determining system. 11. The driving state determnining system of claim 1, wherein the determining unit recognizes the point where the vehicle needs to stop and which is located along the road. 12. The driving state determining system of claim 1, wherein the point where the vehicle needs to stop is fixed at a non-moving location.
