Free-running time identification method, free-running distance identification method, programs for those devices and computers

摘要

PROBLEM TO BE SOLVED: To provide a method for specifying a free running time, a method for specifying a free running distance, a device thereof, and a program for a computer thereof, which specifically specifies the timing of braking applied by a driver when an accident occurs. SOLUTION: This is a method for specifying a free-running time and a free-running distance, which is an index for determining whether or not a driver has properly applied a brake when an accident occurs. An accident determination step for determining whether or not there was an accident, a random intrusion start time identification step for specifying the intrusion start time t1 based on image data taken by an in-vehicle camera when it is determined that there was an accident, and a random intrusion start time identification step. After the intrusion start time t1, the avoidance driving operation time specifying step for specifying the avoidance driving operation time t2 in which the avoidance driving operation for avoiding an accident is performed based on the driving history data of the vehicle stored in the traveling history storage unit The driver includes a free-running time calculation step for calculating the free-running time T1 from the random intrusion start time t1 to the avoidance operation operation time t2.
