Problems solved by technology
[0003] Driving tendency is also easily affected by emotions. Under the influence of sadness, drivers are prone to abnormal driving behaviors such as inattention and driving distraction. The present invention focuses on a dynamic transfer of driver's driving tendency based on sadness. Probability calculation method to study the influence of sadness on driving tendency dynamics, and propose corresponding early warning measures according to dynamic changes of driving tendency, enriching the content research of automobile auxiliary driving system

Embodiment Construction
[0023] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to illustrate the principle of the present invention, but not to limit the scope of the present invention.
[0024] The present invention proposes a sad emotion-based analysis method for the dynamic evolution of driver's driving tendency, which includes the following steps.
[0025] Step 1. Based on traffic big data, respectively obtain driving behavior data and driver physiological data under normal mood and sad mood and extract characteristic parameters, including:
[0026] Select representative driving indicators and physiological indicators of the driver, such as speed, steering wheel angle, accelerator pedal force, brake pedal force, steering curvature, distance between the target car and the center lane, skin electricity, myoelectricity, electrocardiogram, p...

The invention provides a driving tendency dynamic transition probability calculation method considering pessimistic emotions. The method comprises the steps: acquiring driving behavior data and driverphysiological data, and extracting feature parameters; quantitatively representing the driving tendency under the normal emotion and the pessimistic emotion; respectively calculating driving tendencyquantized values under the normal emotion and the pessimistic emotion according to the characteristic parameter data; judging the driving tendency of the driver according to the driving tendency quantized value of the driver; and comparing driving tendency categories under the two emotions and calculating the driving tendency dynamic transition probability. According to the driving tendency dynamic transition probability calculation method under the influence of the pessimistic emotion, the driving tendency transition rule of the driver is explored and the improvement of an automobile auxiliary driving system is facilitated, so that the active safety of the automobile is further improved.
Description
technical field [0001] The invention relates to the field of automobile safety assisted driving, in particular to the aspect of the influence of driver's sadness on dynamic driving tendency. Background technique [0002] More and more traffic accidents have an inseparable relationship with the driver himself. The driver's inability to control his emotions during driving is also one of the main reasons for traffic accidents. In recent years, researchers have gradually realized that in order to reduce traffic accidents, in addition to necessary traffic control, the mental health of drivers is also an important factor. Research on driving emotions is becoming more and more common, especially negative emotions such as anger and anxiety. [0003] Driving tendency is also easily affected by emotions. Under the influence of sadness, drivers are prone to abnormal driving behaviors such as inattention and driving distraction. The present invention focuses on a dynamic transfer of dri...
