Abstract

In a driving recorder, angular velocity data and acceleration data of a vehicle are sequentially measured and stored into a memory along with time information, thereby updating the data stored in the memory in sequence. If a shock due to crash or the like occurs at the vehicle, a given time period is set for further data storage. When the time is up, the data storage into the memory is stopped. Thus, the memory holds at least the angular velocity data and the acceleration data for the set time period after detection of the occurrence of shock and for a given time period before detection of the occurrence of shock. Upon analysis, a travel analyzer is connected to the driving recorder for reading out the data stored in the memory. Based on the read-out data, the travel analyzer produces data representing a travel history of the vehicle and visually expresses such travel history data.
