Example Embodiment

[0038] Example 1

[0039] The existing driving risk platform technologies are divided into two types: ①Statistical calculation of individual alarm factor scores (such as figure 1 ); ②Integrate multiple alarm factors for calculation (such as figure 2 )

[0040] See figure 1 In the prior art, the smart terminal collects information from the driver and the vehicle or road in front to generate an alarm, and the vehicle-mounted host uploads the alarm information to the rear platform in real time. The platform will set a score for each alarm factor, and then calculate the score based on the number of alarms in a single day or per 100 kilometers, and finally judge the driver's pros and cons based on the total score obtained. The core modules of this platform system are the data display module and the data statistical report module that display the information uploaded by the smart terminal.

[0041] See figure 2 , The reason currently existing in the market figure 1 A further developed d...

Example Embodiment

[0044] Example 2

[0045] Such as image 3 As shown, a driver risk evaluation system includes a risk database module 2, a risk review module 3, an environmental data collection module 4, an abnormal data cleaning module 5, a factor assignment module 6, a risk value calculation module 7, and a risk evaluation module 9; The risk database module 2 is used to store driver driving risk data, the risk review module 3 is used to detect risk data and match the data in the database; the environmental data collection module 4 is used to collect driving environment data , The abnormal data cleaning module 5 is used to check risk data; the factor assignment module 6 is used to classify data and assign preset data values; the risk value calculation module 7 is used to perform risk data Calculation; The risk evaluation module 9 is used to analyze and evaluate the driver's driving risk;

[0046] The risk database module 2 inputs the driving risk information to the environmental data collection m...

Example Embodiment

[0065] Example 3

[0066] See Figure 4 The difference from the foregoing embodiment is that the present invention also discloses a driver risk evaluation method, which includes the following steps:

[0067] 1) Input the driver's driving risk information S1;

[0068] 2) Collect driving environment data information S3;

[0069] 3) Calculate the driving risk information S4;

[0070] 4) Evaluate the driver's driving risk information S6.

[0071] Preferably, the step 1) includes collecting S2 of driver driving behavior data.

[0072] Preferably, the step 2) includes assigning values ​​to the driving risk data according to preset conditions. .

[0073] Preferably, the step 2) includes checking the driving risk data to eliminate abnormal data.

[0074] Preferably, the step 3) includes correcting the driving risk data information S5.

[0075] Preferably, the step 4) includes classifying and displaying driving risk information data.

[0076] In this embodiment, the input of the driver's driving ris...

Abstract

The invention discloses a driver risk evaluation system and method. The system comprises a risk database module, a risk review module, an environment data acquisition module, an abnormal data cleaningmodule, a factor assignment module, a risk value calculation module and a risk evaluation module. The risk database module inputs risk information to the environmental data acquisition module throughthe risk review module, the environmental data acquisition module inputs risk information to the factor assignment module through the abnormal data cleaning module, and the factor assignment module transmits the risk information to the risk evaluation module through the risk value calculation module for risk information evaluation. The method comprises the steps of 1, inputting driving risk information of a driver; 2, acquiring driving environment data information; 3, calculating the driving risk information; and 4, evaluating the driving risk information of the driver. The driver risk evaluation system and method are high in driving risk evaluation accuracy, high in stability, reliable, safe and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of risk assessment, and in particular relates to a driver risk assessment system and method. Background technique [0002] my country is a high-incidence area of ​​global logistics traffic accidents, and the annual death toll still ranks second in the world. According to the statistical model of the World Health Organization (WHO), the number of casualties in traffic accidents in my country exceeds 200,000 every year, and 18 people die in traffic accidents for every 100,000 Chinese residents, and about 800 people die in traffic accidents every day. Among them, the casualty rate of operating passenger and truck drivers is nearly 1 / 1000, and the casualties and property losses caused by road traffic accidents responsible for operating passenger and truck vehicles are much higher than the ratio of the number of operating passenger and truck vehicles to the total number of vehicles. [0003] Now with the develop...
