[0128] See also Figure 2 , which is a flow chart of a vehicle warning method for identifying dangerous driving behaviors of a driver proposed in a second embodiment of the present invention, wherein the vehicle warning method for identifying dangerous driving behaviors of a driver comprises steps S11 to S15, wherein:

[0129] Step S11: After collecting the vehicle driving state data and the driver driving state data in real time, the abnormal coefficient is obtained according to the multi-view abnormality detection algorithm, and the abnormal interval of the abnormal coefficient is determined to determine the risk stage of the driver's driving behavior, physiological and psychological state, and determine the probability of the driver's retaliatory driving behavior for corresponding processing;

[0130] Step S12: obtaining a steering wheel touch and pressure image, a facial information image, and a driver's voice information of the driver at the current moment, performing image registration processing on the steering wheel touch and pressure image and the driver's facial information image, and then performing image synthesis, performing image feature extraction and feature enhancement on the synthesized image according to a convolutional neural subnetwork to obtain driver enhanced image features, performing audio feature extraction and feature enhancement on the driver's voice information according to the Mel cepstral coefficient to obtain driver enhanced audio features, generating driver text information according to the driver voice information conversion, and then performing text feature extraction and feature enhancement on the driver's voice information according to the global vector word embedding to obtain driver enhanced text features;

[0131] Step S13: inputting the driver enhanced image features into the first network layer of the multimodal feature fusion subnetwork to obtain the first hidden layer state features, splicing the driver enhanced audio features and the first hidden layer state features into the second network layer to obtain the second hidden layer state features, splicing the driver enhanced text features and the second hidden layer state features into the third network layer to obtain multimodal fusion features, and then performing the driver's dangerous driving behavior judgment to obtain the driver's dangerous driving behavior judgment classification prediction results;

[0132] Step S14: Actively intervene according to the vehicle driving radar data in the vehicle driving status data. When the active intervention determines that the distance between the vehicle and the vehicle, pedestrian or obstacle in front at the current moment is less than the preset first radar distance threshold, control the vehicle deceleration device to decelerate the vehicle. When the active intervention determines that the distance between the vehicle and the vehicle, pedestrian or obstacle in front at the current moment is less than the preset second radar distance threshold, control the vehicle emergency brake to make the vehicle emergency brake to stop. When the active intervention determines that the distance between the vehicle and the vehicle, pedestrian or obstacle in front at the current moment is less than the preset first radar distance threshold or the preset second radar distance threshold, each tire of the vehicle is individually controlled to maintain vehicle body stability. When the active intervention determines that the vehicle collides at the current moment, activate the in-vehicle airbag device to perform active in-vehicle protection, control the engine hood to lift and actively activate the pedestrian protection airbag to perform active outside-vehicle protection.

[0133] It should be noted that the first radar distance threshold in this embodiment is the minimum radar distance value of the current vehicle's rated directional cruise, so that after active intervention, the vehicle can enter the directional cruise state and keep following the vehicle to avoid the expansion of safety accidents caused by emergency stops. The second radar distance threshold in this embodiment is the shortest braking distance at the current vehicle speed, so that after active intervention, the vehicle can brake to a stop and avoid collisions.

[0134] Step S15: When it is determined that the driver is in a dangerous driving state, the vehicle lighting equipment is controlled to flash the high and low beams alternately and turn on the hazard warning lights. The vehicle's external speaker equipment and vehicle horn are then controlled to broadcast danger avoidance warnings and continuously sound the horn for short warnings. Based on the driver's dangerous driving state information, the driver's physiological state data, and the driver's emotional state data, a dangerous driving feedback report is generated and communicated to the cloud alarm system, and an alarm message is automatically sent to the preset emergency target.

[0135] In summary, according to the above-mentioned vehicle warning method for identifying dangerous driving behaviors of drivers, a comprehensive data analysis module and a multimodal feature recognition network are designed by monitoring and identifying the driver's driving behavior, physiological and psychological state in real time, to comprehensively analyze and judge the driver's driving state and driving behavior.
