Description
Technical Field
[0001] The present invention relates to the field of intelligent driving technology, and in particular to a driver behavior evaluation and prediction method and system based on driving scenarios. Background Art
[0002] With the continuous development of intelligent driving assistance technology, more and more functions are applied to intelligent driving cars, which brings great convenience to users. However, due to insufficient understanding of the functions, there is over-reliance and abuse of assisted driving functions, which brings safety risks to users. In order to further improve the intelligence of assisted driving, so that the vehicle can better understand the driver and the driver can better understand the vehicle, it is necessary to evaluate and predict the driver's driving style, so that the driver can better understand the boundaries of the assistance function, and the assistance function can better understand the driver's reaction and driving ability boundaries, so as to provide a safer and smarter interactive experience.
[0003] The current driver behavior assessment method is mainly carried out in two ways. One is to rate the driver's style through driving control actuators, such as the driver's throttle opening, steering angle and other information; the other is to perceive and recognize the driver's face and movements through DMS to judge the driver's concentration, and then issue warnings for unsafe driving conditions such as distraction or drowsiness. However, the information input by these two methods is relatively simple, and the relevant assessment information given based on the level division is also relatively broad. It is difficult to adapt to complex and changing scenarios based solely on the driver's behavior in the car.
[0004] The driving behavior evaluation and prediction method based on driving scenarios provided by the present invention solves the above-mentioned problems of excessive dependence caused by insufficient understanding of the ability boundary of the intelligent assisted driving function by the driver, and insufficient evaluation of different driver styles by assisted intelligent driving, resulting in untimely warning or poor interactive experience. At the same time, it overcomes the problem of limited evaluation information based only on the driver's driving actions and monitoring. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0040] Embodiment 1
[0041] An embodiment of the present invention provides a driver behavior evaluation and prediction method based on a driving scenario, referring to Figure 1 , Figure 2 As shown, including:
[0042] Step S1: Monitor and extract driving scenes, information about people in the car, and driver status information.
[0043] In a specific embodiment of the present invention, step S1 includes:
[0044] Use external sensors to collect driving scenarios, including lane lines, surrounding vehicle trajectories, traffic light status, weather conditions, and road surface characteristics;
[0045] Use DMS to monitor driver status information, including driver pupil movement, eye closure time, head posture, and operation information;
[0046] Specifically, the driver's physiological and behavioral data, including pupil movement, eye closure time, head posture, and operation data, including: throttle force, brake force, and steering wheel angle rate, are obtained through the driver monitoring system (DMS).
[0047] Use the in-vehicle monitoring system to monitor the number of passengers and seat distribution in the vehicle, or use the out-of-vehicle monitoring system to monitor the type of load, weight and volume distribution of the load.
[0048] Specifically, external vehicle sensors include: cameras, millimeter-wave radars, and lidars; driving scenarios include lane lines, surrounding vehicle trajectories, traffic light status, weather conditions (such as rain, snow, and fog) and road surface features (such as curves and ramps).
[0049] Step S2: Establish a driving scenario and environment model according to the driving scenario, establish a vehicle use scenario model according to the information of the occupants in the vehicle, and generate a driver model as well as intelligent driving performance parameters and driver behavior evaluation parameters according to the driver status information of the driver in different driving modes.
[0050] In a specific embodiment of the present invention, in step S2, a convolutional neural network is used to extract features from the collected image data of different driving scenes, classify and identify changes in driving scenes, identify driving scenes such as lane changing, overtaking, and following a vehicle, and combine with a dynamic time series model to capture the changing patterns of driving scenes over time, so as to achieve accurate modeling of the dynamic driving scene characteristics of the vehicle.
[0051] In a specific embodiment of the present invention, in step S2, the K-means clustering algorithm is used to classify the information of the occupants and the driver's status information, extract typical driving habits (such as aggressive driving and conservative driving), and use the dynamic time warping algorithm to analyze the consistency of the driver's operating behavior in different driving scenarios, and build a driver model in combination with the driver's long-term behavior data.
[0052] Step S3: Comprehensively evaluate the driver's driving behavior and driving style during manual driving based on the driving scenario and environment model, the vehicle scenario model and the driver model to adjust and predict intelligent driving performance parameters and driver behavior evaluation parameters.
[0053] In a specific embodiment of the present invention, in step S3, the driver's operating behavior in different driving scenarios is statistically analyzed, the lane change time, speed difference with the front vehicle, relative distance and curvature control speed in the curve scene under different driving scenarios are extracted, and the intelligent driving performance parameters and driver behavior evaluation parameters are generated using a multi-objective optimization algorithm.
[0054] Specifically, the driver's behavior is comprehensively evaluated in the manual driving mode. By extracting different scenarios and driver manipulation, the driver's behavior is comprehensively evaluated, such as lane change time, habits during overtaking, speeds at different curves, following distance, and reaction time to dangerous scenes. First, by statistically analyzing the driver's operating behavior in different scenarios, quantitative parameters such as lane change time, speed difference with the front vehicle, relative distance, and curvature control speed in the curve scene are extracted; combined with the driver's reaction time to dangerous scenes (such as sudden jamming), throttle and brake operation characteristics, the driver's style is comprehensively determined, and a quantitative model of driving behavior is established. Subsequently, a time series prediction model (such as LSTM or GRU) is used to model and predict the driver's operating behavior during driving. Combined with the output of the scenario model, driver behavior model, and in-vehicle scenario model, personalized driving performance parameters such as acceleration change rate, braking force, and steering response speed are generated through a multi-objective optimization algorithm.
[0055] In the intelligent driving mode, the intelligent driving system strategy is dynamically adjusted based on personalized driving performance parameters. For example, in highway scenarios, the following distance is dynamically optimized based on the passenger information in the car; during braking, the comfort of the braking process is improved by adjusting the deceleration change rate; in bad weather or dangerous scenarios, the vehicle control response time and alarm threshold are adjusted according to the driver's style to ensure safety and reliability.
[0056] Step S4: Optimizing and adjusting the driving strategy during the intelligent driving process based on the driving performance parameters and the driver behavior evaluation parameters.
[0057] This application continuously optimizes and enriches driving scenarios and refines evaluation indicators to continuously improve the safety and interactive experience of intelligent driving. The present invention realizes a closed loop of the entire process from data collection to behavior modeling, evaluation prediction and strategy optimization, ensuring more accurate driving behavior evaluation and significantly improving the safety and interactive experience of intelligent driving.
