Location based service (LBS) database-based vehicle information collection device and risk analysis method

The invention relates to a vehicle information collection device, and particularly relates to a location based service (LBS) database-based vehicle information collection device and a risk analysis method. The collection and the analysis on travel information are achieved through a travel data collection system, the travel information is transmitted to a vehicle search platform service system to be processed through a general packet radio service (GPRS) wireless network, so as to obtain main living range score data, work range score data, consumption range score data, flow range score data, vehicle feature score data and vehicle user score data of a vehicle owner, thereby obtaining total information score data of a currently used vehicle of an owner. A financing institution can foresee the probability of default of the vehicle owner in advance according to the travel information analysis result after the vehicle owner exceeds the time limit, so as to judge the repayment willingness and the loan repayment ability of the vehicle owner, and take measures as soon as possible aiming at a borrower who does not repay maliciously and illegally disposes or pledges the vehicle. Thus, the economic risks of the financing institution and an insurance company are effectively reduced.
