The invention relates to a head-up display adjusting method, system and device based on emotion recognition and a medium. The method comprises the following steps: acquiring a face video frame sequence of a driver and a physiological signal sequence corresponding to the face video frame sequence; inputting the face video frame sequence into an expression recognition model, and extracting an expression feature sequence of the face video frame sequence; extracting a physiological feature sequence from the physiological signal sequence according to a physiological feature extraction model; inputting the expression feature sequence and the physiological feature sequence into a multi-modal emotion recognition model to generate an emotion category; and dynamically adjusting the head-up display content on the vehicle according to a preset adjustment strategy based on the emotion category. The head-up display content is dynamically adjusted according to the emotion of the driver, and the driving safety is improved.

The invention discloses a vehicle man-machine interaction method and device and a computer program product, and the method comprises the steps: receiving and recognizing a voice instruction and a gesture instruction of a passenger in a vehicle; monitoring the state of the driver in real time; if the driver is in the normal state, executing a corresponding instruction according to a preset execution rule according to the input sequence of the voice instruction and the gesture instruction and whether a conflict exists or not; if the driver is in the fatigue or distraction state, the safety reminding instruction is executed firstly, and after confirmation of the driver is obtained, the corresponding instruction is executed according to the instruction execution logic that the driver is in the normal state. Through the innovative vehicle man-machine interaction method, the driving safety and the in-vehicle interaction experience are remarkably improved; not only is human-vehicle interaction logic optimized, but also a safer, more comfortable and more personalized driving environment is provided for a user through an intelligent control mode.

The utility model provides a multifunctional vehicle-mounted magnetic wireless charger, which relates to the technical field of magnetic wireless chargers, and comprises an adjusting mechanism, one side of the adjusting mechanism is provided with an auxiliary mechanism, the adjusting mechanism comprises a shell, the bottom end of the shell is provided with a bottom support, the bottom end of the shell is correspondingly contacted with the top end of the bottom support, and the bottom end of the shell is connected with the bottom end of the bottom support. A lead screw is arranged on the inner wall of the center of the bottom support, and the inner wall of the center of the bottom support is connected with the outer side of the lead screw in a penetrating and threaded mode. The screw rod is rotated and moves on the original basis by screwing the rotating handle, the top end of the screw rod is connected with the fixed disc, and the fixed disc is positioned at the center of the adsorption part, so that the height of the adsorption part in the shell is increased, and the distance between the adsorption part and the top side in the shell is shortened; therefore, the adsorption capacity of the mobile phone is improved, the mobile phone is immovable during jolting, the falling risk caused by vibration is fundamentally eradicated, and a safe driving environment is created for a driver.

The invention discloses a vehicle multi-screen combined display method and system, a vehicle and a storage medium, and the method comprises the steps: controlling an instrument screen to display an image processed by a micro-control unit in response to a vehicle starting signal; after the system-on-chip is successfully started and display content is output to the instrument screen, the instrument screen is controlled to be switched to an image output by the system-on-chip, and the instrument screen is connected with the micro-control unit and the system-on-chip at the same time; and continuously monitoring the state of the system-on-chip by using the micro-control unit, and controlling the instrument screen to switch back to the display content output by the control unit when the system-on-chip fails or is stuck. According to the method and the device, the technical problem that an instrument does not display content directly when an SOC (System On Chip) fails in the prior art is solved.

This invention relates to the technical fields of tunnel safety control, intelligent transportation, vehicle-road cooperation, and tunnel safety early warning. Specifically, it relates to a tunnel active safety control system and method based on vehicle-road cooperation. Key technical points include: a multi-source data fusion module: integrating data from roadside equipment (including radar, cameras, and fiber optic sensors) and vehicle-mounted terminals to construct a four-dimensional perception network of people, vehicles, roads, and the environment; a dynamic risk assessment module: quantifying the probability of an accident (P) and collision energy loss (E) based on an equivalent traffic conflict number (ECN) model to achieve risk-level early warning; and a vehicle-road cooperative intervention module: triggering early warning and control strategies from both the roadside and vehicle perspectives through two-way communication between roadside smart guidance signs, information boards, and vehicle-mounted terminals. This invention improves the ability to respond to tunnel risks.
