Vehicle behavior analysis system
First Claim
1. 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 includinga sampling part that samples the behavior data sequentially, anda 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 includinga 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, anda 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.

Abstract
A vehicle behavior analysis system performs an analysis of vehicle operation by displaying behavior data in an organized and analyzed form. A vehicle behavior data collecting unit records information on the vehicle'"'"'s driving as behavior data and an analysis unit analyzes a recorded content of the vehicle behavior data collecting unit. A recorded data unit obtaining part obtains the recorded data units recorded in a memory of the vehicle behavior data collecting unit and a displaying part displays the content concerning at least a predetermined item among the contents shown by obtained each recorded data unit in a form of a table sectioned for each recorded data units and arranged at a side of the analysis unit, and a risk degree calculated based on the content shown by each recorded data units is contained in the predetermined item displayed by the displaying part.
