Patent ID: 8798919

Claim:
A driving characteristics detector comprising: a central processing unit (CPU), the CPU is configured to obtain, in a driving information obtaining element, driving information, which relates to a driving condition of a vehicle; and determine, in a driving characteristics determining element, driving characteristics of a driver of the vehicle based on the driving information, wherein the driving information includes vehicle speed relating information, which relates to at least one of a vehicle speed, acceleration and deceleration of the vehicle, wherein a driving unit section is defined as a section from the vehicle starts to go until the vehicle stops, and wherein the driving characteristics determining element determines the driving characteristics based on the vehicle speed relating information in each driving unit section; wherein the CPU is further configured to determine, in a second adaptation determination element, based on the driving information in each driving unit section whether the vehicle speed relating information in the driving unit section is suitable for determining the driving characteristics, wherein the second adaptation determining element determines that the vehicle speed relating information is not suitable for determining the driving characteristics when the vehicle speed does not exceed a predetermined value, wherein the driving characteristics determining element determines the driving characteristics based on the vehicle speed relating information other than not-suitable vehicle speed relating information in the driving unit section.
