Abstract

A physical response record system includes a main unit and various sensors for recording driver'"'"'s conditions and vehicle operations by a driver. The driver'"'"'s conditions in combination with the vehicle operations are used to determine a risky situation of the vehicle based on an averaged driver'"'"'s condition and the like. The risky situation is further analyzed for detecting a risky object and stored as a record for later use.

a surrounding condition data acquisition unit for acquiring condition data of a surrounding condition of the vehicle; and

a condition determination unit for determining the surrounding condition of the vehicle based on the condition data acquired by the surrounding condition data acquisition unit, wherein

the storage unit stores the surrounding condition determined by the condition determination unit.

5. The physical response record system as in claim 1 further comprising:

a communication unit for providing communication with an external control station; and
