Patent ID: 7676306

Claim:
A vehicle behavior analysis system that is arranged on a vehicle comprising: a vehicle behavior data collecting unit that records information on the vehicle's driving operation as behavior data, the vehicle behavior data collecting unit including a sampling part that samples the behavior data sequentially, and a data recording part that records, when the sampled behavior data meets a predetermined condition, behavior data during a certain time period before and after the sampled behavior data as recorded data units in a built-in memory; and an analysis unit for analyzing a recorded information of the vehicle behavior data collecting unit, the analysis unit including a recorded data unit obtaining part that obtains the recorded data units containing vehicle acceleration data in the memory of the vehicle behavior data collecting unit, and a displaying part that displays on a display contents of the recorded data units and a risk degree corresponding to the recorded data units in a table, wherein the risk degree is calculated from an acceleration value at a time of a peak acceleration shown by the vehicle acceleration data and an acceleration value during a substantial acceleration applying period, the substantial acceleration applying period containing the time of the peak acceleration.
