Embodiment Construction

[0044] The present invention is described in detail below in conjunction with accompanying drawing:

[0045] refer to figure 1 , the present invention first discloses an evaluation system for implementing a vehicle driving risk evaluation method considering a driver's driving style, and the evaluation system includes:

[0046] Data acquisition module 101: for acquiring vehicle driving data;

[0047] Driving style fuzzy inference module 102: used to evaluate the aggressiveness of the driver;

[0048] Vehicle driving state prediction module 103: used to predict which of the vehicle driving state is free running, car-following, or lane-changing;

[0049] Driving risk degree fuzzy reasoning module 104: used for evaluating the driving risk degree;

[0050] Driving style correction module 105: used to correct the driving risk by using the aggressiveness of the driver;

[0051] The vehicle driving risk evaluation method considering the driver's driving style uses a hidden Markov ...

Abstract

The invention discloses a vehicle driving risk evaluation method considering a driving style, which overcomes the problems that the prior art does not take into account the differences of driving habits of drivers with different styles, and the evaluation method is not personalized and humanized. The method comprises the following steps: 1) evaluating the driver's radical degree by using historical driving control data; 2) predicting that driving state base on the real-time vehicle running data and using the hidden Markov model; 3) for different driving states, establishing the fuzzy controller with different characteristic parameters to evaluate the driving risk; 4) using the driver's radical degree to correct the drive risk degree to obtain the final driving risk degree: carrying out thesuperposition correction of the driver's radical degree on the value of the drive risk degree in the range of [0.3, 0.7], and obtaining the final driving risk degree output result; therefore, for drivers with high or lower aggressiveness, the driving risk value within [0.3, 0.7] will increase or decrease.

Description

technical field [0001] The present invention relates to a traffic safety evaluation method in the technical field of intelligent traffic system active safety, more precisely, the present invention relates to a vehicle driving risk evaluation method considering driving style. Background technique [0002] With the development of the economy, the number of cars continues to increase, the traffic pressure increases, and traffic problems occur frequently. Road traffic safety has become an urgent issue. According to the statistics of the United Nations, about 1.2 million people die in traffic accidents around the world every year. Serious economic losses and casualties. The essence of vehicle active safety is to detect the driver’s driving safety status, vehicle operating status and environmental information in real time, identify and predict the driving risk status and give timely reminders, and actively intervene in the interference or control of vehicle operation when necessar...
