step S3, when judging that the body condition of the driver is normal, acquiring the current driving information;
and step S4, judging the negative emotion type of the driver according to the current driving information, and executing a corresponding emotion relieving strategy according to the negative emotion type.
Specifically, as shown in FIG. 2, step S1 includes steps S101-S103:
and step S101, acquiring a face image of a driver during driving. The facial image of the main driving personnel can be collected through the camera arranged in the main driving area.
And step S102, extracting facial feature information from the facial image.
And S103, processing the facial feature information by adopting a pre-trained deep neural network model, and carrying out emotion recognition on the driver according to the facial feature information to obtain an emotion recognition result.
Specifically, facial feature information is input into a pre-trained deep neural network model, and an emotion recognition result is determined according to a result output by the deep neural network model; the deep neural network model can be obtained by training a large amount of micro-expression data of drivers stored by a server. The invention identifies the emotion of the driver by using the facial features, thereby ensuring the accuracy of emotion identification.
When the emotion recognition result is that the driver is in a negative emotion, the process proceeds to step S201, otherwise, the routine ends.
Step S201, acquiring physiological characteristic parameters of the driver, and judging whether the physical condition of the driver is abnormal or not according to the physiological characteristic parameters.
The physiological characteristic parameter may be a blood pressure value, a pulse value, a blood oxygen value, and the like. Specifically, the current physiological characteristic parameters of the driver may be obtained through a sensor, for example, the physiological characteristic parameters such as a blood pressure value, a pulse value, and a blood oxygen value are obtained through measurement by a sphygmomanometer, a pulse oximeter, and the like, and the health condition of the driver is determined according to the obtained physiological characteristic parameters. Specifically, the characteristics of various collected physiological characteristics can be selected through a Relief algorithm; performing main factor quantization on the selected parameter value of each target physiological characteristic, and determining the quantization weight of each target physiological characteristic; whether the physical health condition of the driver is abnormal is determined through the evaluation indexes of various target physiological characteristics. The latest basic physical examination report of the driver can be directly acquired from the server, and whether the health condition of the driver is abnormal or not can be judged according to the basic physical examination report. For example, if the basic physical examination report indicates that the blood pressure of the driver is high, it can be determined that the physical health condition of the driver is abnormal.
When the health condition of the driver is judged to be normal, the negative emotion is not caused by the disease, the negative emotion needs to be analyzed, a targeted emotion relieving strategy needs to be provided, the step S301 is entered, and when the health condition of the driver is judged to be abnormal, the negative emotion is caused by the disease, the step S501 is entered.
Step S301, when judging that the health condition of the driver is normal, acquiring current driving information.
Specifically, the current driving information may be information such as a continuous driving time, brightness of an environment around the vehicle, or a current traffic road condition, the type of the negative emotion is determined according to the current driving information, and a subsequent emotion mitigation strategy is executed. There are various causes of negative emotions, which may be caused by external objective causes or physical diseases. According to the invention, the negative emotion is accurately identified and distinguished, the negative emotion relieving strategy is executed only when the driver is in a healthy state, and other emergency treatment is carried out on the disease state.
And S401, judging the negative emotion type of the driver according to the current driving information, and executing a corresponding emotion relieving strategy according to the negative emotion type.
Judging the negative emotion type of a main driver based on the driving information of the user, specifically, performing rule matching in a pre-stored rule list based on the driving information of the user, wherein the rule list comprises a plurality of rule records for determining the negative emotion type; if the user driving information is successfully matched with the rule record, obtaining the current negative emotion type of the main driver according to the successfully matched rule record; and if the rule matching fails, determining the negative emotion type of the main driver as a preset standard negative emotion type. Further, the system can also preset a strategy library for storing the emotion relieving strategies corresponding to various negative emotion types, and after the negative emotion types of the main driver are determined, the emotion relieving strategies corresponding to the negative emotion types can be selected from the strategy library according to the negative emotion types, and the emotion relieving strategies are executed.
Specifically, referring to fig. 3, if the driving information is successfully matched with the rule that "the continuous driving time is longer than the set driving time threshold", determining the negative emotion type of the driver as a first negative emotion type, and executing a first corresponding negative emotion mitigation strategy: playing the mood relieving music, and if the continuous driving time is long enough, for example, more than 10 hours, further recommending designated driving personnel to the driver, wherein the designated driving personnel can be designated driving personnel within a preset range, or driving personnel who go to the same destination at the same time period and have car sharing requirements. When the driving information is successfully matched with the rule that the brightness of the surrounding environment of the vehicle is smaller than the set environment brightness threshold value, determining the negative emotion type of the driver as a second negative emotion type; and executing a corresponding negative emotion relieving strategy two: and adjusting the brightness of the lamplight in the vehicle, and specifically matching a corresponding scene lighting scheme by combining the current environment image or audio style in the vehicle. And when the driving information is successfully matched with the rule of 'congestion of the traffic road condition', determining the negative emotion type of the driver as a third negative emotion type, wherein the congestion of the traffic road condition can be judged by judging that parameters such as the frequency of frequent braking of a user, the time of slow driving of the vehicle speed within a preset time period or the queuing length of a front train exceed a set value. And when the driver is in a third negative emotion type of traffic jam, executing a corresponding negative emotion relieving strategy III: safety prompting voice is pushed to the driver, and auxiliary driving opinions of the same navigation route and the same vehicle type can be further recommended, such as a better driving route. According to the method and the device, the corresponding emotion relieving strategy is selected according to the type of the negative emotion, so that the emotion relieving strategy is more targeted, the actual requirements of a driver are met, and the emotion is relieved more effectively.
And step S501, when the health condition of the driver is judged to be abnormal, starting automatic driving or prompting the driver to stop the vehicle to the temporary stop point.
When the body of the driver is in a diseased state, it is highly likely that the negative emotion of the driver is caused by the disease, at which time the driver is not suitable to continue driving. Therefore, the positioning system acquires a temporary parking spot for convenient parking based on the current position, and then starts automatic driving or prompts the driver to park the vehicle at the temporary parking spot. The embodiment can ensure the life safety of the driver.
Optionally, step S601 may further include that after the vehicle stops at the temporary parking spot, the vehicle-mounted communication system makes an emergency call or sends emergency information to the emergency center or an emergency contact preset in the vehicle.
Corresponding to the method for relieving the negative emotion of the driver provided by the first embodiment of the invention, the second embodiment of the invention also provides a system for relieving the negative emotion of the driver, which comprises the following steps:
the emotion recognition unit is used for acquiring facial feature information of a driver during driving, and performing emotion recognition on the driver according to the facial feature information to obtain an emotion recognition result;
