detailed description

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, it is a work flow chart of a kind of driving behavior evaluation method of the present invention, comprising:

Step S101, including: obtaining the driving behavior evaluation of the driving vehicle from the driving vehicle of the driver to be evaluated;

Step S102, comprising: obtaining the roadside driving behavior evaluation of the driving vehicle from a roadside unit arranged on the road;

Step S103, comprising: acquiring other vehicle driving behavior evaluations about the driving vehicle from vehicles other than the driving vehicle;

Step S104 includes: determining a comprehensive driving behavior evaluation of the driver to be evaluated according to the driving behavior evaluation of the driving vehicle, the roadside driving behavior evaluation and the other vehicle driving behavior evaluations of the driving vehicle.

The present invention is preferably implemented by a V2X system. V2X, the full name of VehicletoX, is a technology that realizes interconnection between vehicles and between vehicles and facilities through a short-range communication protocol. Wherein, step S101 preferably obtains the driving behavior evaluation of the driving vehicle from an Onboard Unit (OBU) provided on the driving vehicle through a 3G/4G connection. Step S102 is preferably connected through a network (Internet), and obtains roadside driving behavior evaluation from a roadside unit (RoadsideUnit, RSU) arranged on the road. Step S103 preferably obtains the driving behavior evaluation of other vehicles from the OBU installed on other vehicles through 3G/4G connection.

After the driving behavior evaluation of the driving vehicle, the roadside driving behavior evaluation and the other vehicle driving behavior evaluations are obtained through step S101-step S103, the driving behavior of the driver to be evaluated corresponding to the driving vehicle can be comprehensively determined. Comprehensive evaluation of behavior. The comprehensive evaluation of driving behavior includes the driving behavior evaluation of the driving vehicle, the roadside driving behavior evaluation and the driving behavior evaluation of other vehicles.

The present invention conducts omnidirectional and multi-angle comprehensive evaluation by driving the vehicle itself, the roadside unit and other vehicles, so that the obtained comprehensive evaluation of driving behavior is more reliable and avoids unobjective single evaluation. At the same time, since the evaluation comes from the driving vehicle itself, the roadside unit and other vehicles, the present invention decouples the evaluation, avoids confusion between different evaluations, and reduces the complexity of comprehensive evaluation.

In one of the embodiments, the step S101 specifically includes:

Obtain at least one driving behavior of the driver from the vehicle where the driver to be evaluated is located, as well as the fuel consumption of the driving vehicle and the corresponding speed of the driving vehicle when the driving behavior occurs;

Obtain the comparison data of average fuel consumption and average speed of vehicles of the same type as the driving vehicle;

Using the average fuel consumption corresponding to the average speed of each of the driving vehicles in the average fuel consumption and average vehicle speed comparison data as the comparative fuel consumption of each of the driving vehicle speeds;

Calculate the difference between the fuel consumption of the driving vehicle and the fuel consumption of the corresponding driving vehicle speed to obtain a fuel consumption difference, associate the fuel consumption difference with the driving behavior that occurs, and use multiple fuel consumption differences and associated driving behaviors as A driving behavior evaluation of the driving vehicle with respect to the driving vehicle.

The driving behavior of this embodiment is related to the fuel consumption of the driving vehicle and the speed of the driving vehicle. Therefore, the fuel consumption of the driving vehicle produced by the driving behavior of the driver at the speed of the driving vehicle can be obtained. Compared with the vehicle speed, it can be obtained whether the fuel consumption of the driving vehicle generated by the driving behavior at the driving vehicle speed is fuel-efficient or fuel-efficient relative to the average fuel consumption.

Specifically: the background server will pre-collect the average speed and average fuel consumption of the same model to form a fuel consumption curve, as shown in Fig. Behavior, first obtain the relevant driving vehicle speed, and then compare it with the fuel consumption curve shown in Figure 2. If the fuel consumption of the driving vehicle at the same speed is higher than the average fuel consumption, it indicates that the driving behavior has high fuel consumption, as shown in Figure 2 Mark point 21, if the fuel consumption of the driving vehicle at the same speed is lower than the average fuel consumption, it indicates that the fuel consumption of the driving behavior is low, as shown in the mark point 22 in FIG. 2 . The difference between the fuel consumption of the driving vehicle and the average fuel consumption is the fuel consumption difference. Thus, each driving behavior is stored in association with the corresponding fuel consumption difference as the driving behavior evaluation of the driving vehicle.

Preferably, the difference in fuel consumption is divided into several grades, and the driving behavior is stored in association with each grade as an evaluation of the driving behavior of the driving vehicle.

Among them, the driving behavior includes: sudden braking behavior, specifically:

By the braking state, it can be judged whether the user has the behavior of sudden braking; by the steering state, it can be judged whether the user has the behavior of making a sharp turn.

Therefore, through the comprehensive analysis of vehicle speed, accelerator state, brake state and vehicle average fuel consumption, it can be judged that the user's driving habits will reduce or increase fuel consumption. The analysis results are uploaded to the background server through the 3G/4G module.

In one of the embodiments, the step S102 specifically includes:

Obtaining a judgment about the consistency between the driving behavior of the driving vehicle and the driving requirements on the road where the roadside unit is located from the roadside unit arranged on the road as the roadside driving behavior evaluation of the driving vehicle.

Driving requirements include: road speed limit, current signal light status, etc. The roadside unit RSU can judge whether the driving vehicle is speeding by comparing the speed of the driving vehicle with the road speed limit recorded by itself; by comparing the driving state of the driving vehicle with the current signal light state, it can judge whether the driving vehicle has violated the traffic signal driving behavior. The RSU communicates with the OBU of the driving vehicle through DSRC (dedicated short-range communication protocol) or LTE-VDC (LTE-based short-range communication protocol) to determine the driving vehicle, and connects to the background server through the Internet to upload roadside driving behavior evaluation.

In one of the embodiments, the step S103 specifically includes:

Acquiring favorable or negative evaluation data on the driving vehicle from vehicles other than the driving vehicle as other vehicle driving behavior evaluations on the driving vehicle.

Through OBU-OBU communication, such as DSRC (dedicated short-range communication protocol) or LTE-VDC (LTE-based short-range communication protocol) communication, the location and license plate number of surrounding vehicles can be obtained. When the surrounding vehicles give way to the owner (for example, let the owner pass first when meeting the car), the owner can give a good review of the vehicle; The positive/negative review data will be uploaded to the background server through the 3G/4G module.

In this embodiment, other vehicles collect data of positive or negative comments on the driving vehicle, so as to obtain evaluations of driving behavior from the perspective of other vehicles. At the same time, the evaluation of other vehicles is relatively simple, and the impact of the evaluation process on the driver's attention is reduced as much as possible.

In one of the embodiments, it further includes: a pushing step, including: according to the comprehensive evaluation of the driving behavior of the driver to be evaluated, pushing push information consistent with the comprehensive evaluation of driving behavior to the driver to be evaluated.

The background server can set different push conditions, and obtain the corresponding drivers to be evaluated for the comprehensive evaluation of driving behaviors that meet the push conditions, and push relevant information to them by email or SMS.

Typical application scenarios are as follows:

Vehicle manufacturers can select green users, law-abiding users, etc. based on the user's driving habits, and give certain rewards to improve the user's driving habits while improving the freshness and satisfaction of the user;

Based on the user's driving habits, the insurance company can increase the insurance discount for users who drive safely, and increase the insurance rate for users who drive dangerously, so as to attract high-quality users and reduce the risk of claim settlement.

In this embodiment, the third party can push matching push information according to the comprehensive evaluation of driving behavior, so that the push information is more relevant to the driver.
