[0127] Step 550: Display the graphic information on the front windshield through the LED screen (such as Figure 6 shown).

[0128] In an optional manner, controlling the digital projection headlight to project the headlight graphic warning information includes:

[0129] Determining a semiconductor switch in the digital projection headlight that needs to be turned on according to the headlight graphic warning information;

[0130] generating a switch control instruction based on the turned-on semiconductor switch and the projection area;

[0131] The switch control instruction is transmitted to the digital projection headlight, so that the digital projection headlight performs projection in a projection area based on the switch control instruction.

[0132] In a specific embodiment, the digital projection headlight of this embodiment adopts DLP digital projection headlight. DLP digital projection headlight has a projection resolution of millions of pixels, integrated with DMD digital microchip (DMD chip is a semiconductor optical switch containing millions of reflective mirrors), can achieve precise control, the propagation path and brightness range of the light beam change with the angle of the micro-reflector, and can realize a variety of personalized lighting modes through the programming function of the system. In the application of this technology, when the sentinel alarm is activated, the DMD digital chip receives the alarm instruction, and processes the set headlight graphic alarm information, determines the semiconductor switch that needs to be turned on, and realizes the projection of the alarm graphic information through the reverse projection of these millions of reflective mirrors.

[0133] For better explanation, the display of the digital projection headlight includes steps 710 to 740, specifically:

[0134] Step 710: Generate a light language combination code through the vehicle-side customized headlight graphic warning information.

[0142] It should be noted that the preset distance is the default projection distance set by the user to the ground in front of the vehicle, which can range from 0 to 10m. If the front of the vehicle is facing a wall, this embodiment can automatically calculate the wall distance from the vehicle to the front wall and automatically adjust it to the wall distance.

[0143] Beneficial Effects

[0144] This embodiment uses LED screens and digital projection headlights to issue warnings, allowing people around the vehicle to clearly understand that the vehicle has entered alarm mode, which is helpful in preventing vehicle damage. At the same time, by identifying the ground and walls at a preset distance from the vehicle, it can avoid the problem of unclear warning information due to wall obstruction when the digital projection headlights are projected onto the ground, thereby improving the intelligence of the digital projection headlights and helping to improve the accuracy of vehicle safety warnings.

[0145] Figure 2 FIG. 2 is a flow chart showing another embodiment of the vehicle safety warning control method of the present invention, which is executed by a vehicle safety warning control device. Figure 2 As shown, the method comprises the following steps:

[0146] Step 210: The Sentinel warning system is activated.

[0147] Step 220: Determine whether the vehicle is powered off: if so, execute step 230, if not, the system is in standby mode.

[0149] Step 240: The system keeps working.

[0150] Step 250: Determine whether the vehicle is vibrating or whether someone has stayed near the vehicle for a long time.

[0151] Step 260: When the vibration level is greater than 0.1 m / s 2 Less than 0.2m / s 2 Or when the stay duration is greater than 30 seconds, execute step 280.

[0152] Step 270: When the vibration level is greater than 0.2 m / s 2 Or if the suspicious target still does not move away after triggering the Level 1 warning for 30 seconds, execute step 290.

[0157] In an optional manner, the sentinel warning system further includes: an ultrasonic sensor and a vibration sensor. When the sentinel warning system is activated, the sensing data of the vehicle is obtained, including:

[0158] Activating the ultrasonic sensor and the vibration sensor;

[0159] When the ultrasonic sensor detects that a foreign object resides within a safe distance and the residence time is greater than an alarm time threshold, generating ultrasonic data;

[0160] When the vibration sensor detects that the vibration amount is greater than the vibration amount threshold, generating vibration data;

[0161] The ultrasonic data and the vibration data are used as the sensing data.

[0162] In a specific embodiment, the sentinel warning system also includes: a surround view camera, a monitoring device, a domain controller, a lighting controller, a vehicle-mounted networking terminal TBOX and a lighting actuator, and performs real-time detection of the surrounding environment through the ultrasonic sensor and the vibration sensor.

[0163] In addition, millimeter-wave radar, surround-view camera, inertial navigation, and lidar are used as perception sensors to detect the surrounding environment. When the perception sensor detects or monitors that there are suspicious targets (pedestrians, two-wheeled vehicles, vehicles, etc.) approaching the vehicle or the body is vibrating, the sensor will send the vehicle vibration amount, the distance and residence time of the suspicious target, and the video collected by the surround-view camera of the dangerous vehicle to the domain controller. The executable program in the domain controller determines whether the preset conditions for triggering the alarm are met and triggers the sentinel alarm.

[0164] In an optional manner, when the perception data is within a preset warning perception threshold interval, generating an alarm instruction corresponding to the current warning perception threshold interval includes:

[0165] If the ultrasonic data is in the first ultrasonic warning interval or the vibration data is in the first vibration warning interval, a first-level alarm instruction is generated;

[0166] If the vibration data is in the second vibration warning interval or at least two first-level warning instructions are generated within a preset time range, a second-level warning instruction is generated; wherein, the first vibration warning interval is smaller than the second vibration warning interval.

[0167] In a specific embodiment, the potential damage level is used to determine whether a first-level alarm, a second-level warning, or a third-level alarm is triggered. The severity of the third-level alarm is higher than that of the second-level alarm, and the severity of the second-level warning is higher than that of the first-level alarm. The three different levels of alarm behaviors include the lighting of the central control screen in the car, the double flashing prompt, the light language warning / warning, the LED screen warning / warning, and whether to honk the horn, and send an alarm message to the user's mobile phone APP or call the user's mobile phone to distinguish. Among them, the vehicle horn warning will be distinguished according to day and night. The LED screen alarm is displayed on a separate LED screen on the front windshield, and supports custom editing of graphics and text. The light language warning is to project interactive text or patterns onto the ground or wall through the DLP digital projection headlights, and supports custom editing of projected text or patterns on the vehicle side.

[0168] In a specific embodiment, the alarm behavior triggering conditions are as follows:

[0169] 1) When the system detects that the distance between the suspicious target and the vehicle is less than 30cm (i.e. the safe distance described in the present invention, which can be calibrated) and the dwell time is greater than 30 seconds (i.e. the alarm duration threshold described in the present invention, which can be calibrated) or the vehicle detects a vibration greater than 0.1m / s 2 (calibrable) less than 0.2m / s 2 (calibratable) (i.e. the first vibration warning interval described in the present invention), triggering a first-level alarm: 1. Light warning, 2. Warning information on the central control screen in the car, 3. LED screen warning.

[0170] 2) If the vehicle detects a vibration greater than 0.2m / s 2 (calibratable) (i.e. the second vibration warning interval described in the present invention) or the suspicious target does not move away after triggering the first-level alarm for 30s, the second-level alarm will be triggered: 1. Light language hazard warning, 2. Continuous double flash, 3. LED hazard warning, 4.

[0171] 3) When the vehicle triggers the second-level alarm ≥ 2 times within 1 minute (the frequency can be set), the vehicle can upload the alarm moment video to the user's mobile phone APP through TBOX, send the owner a text message to warn that the vehicle has detected an abnormality, or call the user's app-bound mobile phone to notify the user of the abnormal situation (which can be customized by the user).

[0172] It should be noted that the first-level alarm applies to the following situations: 1. When a dynamic object is detected around the vehicle and the distance is less than 30cm (calibrable) and the residence time is greater than 30 seconds (calibrable), the sentry mode first-level alarm is triggered; 2.
