and the car lamp 4 is used for flashing according to the alarm signal.

In particular, the second preset distance may be 30 meters or 20 meters. When the controller 3 calculates the speed of the target object according to the second distance between the target object and the vehicle in different time periods, the picture acquisition device 2 is started, and at the moment, the picture acquisition device 2 acquires a picture and then sends the picture to the controller 3; the controller 3 judges the type of the target object according to the picture, and if the type of the target object meets the alarm type, an alarm signal is generated; if the category of the target object does not satisfy the alarm category, no alarm signal is generated. Target objects include, but are not limited to, humans, vehicles, and animals, among others. When the target object is a person or a vehicle and the third distance between the target object and the vehicle is within a second preset distance range, generating an alarm signal; when the target object is an animal, no alarm signal is generated.

Further, the radar 1 is used for generating a prompt signal under the condition that the target object is not detected;

and the controller 3 is used for controlling the vehicle lamp to stop flashing according to the prompt signal.

Further, referring to fig. 2, a sunlight sensor 5 is also included;

Further, the controller 3 is configured to control the car light to stop flashing and turn off the radar 1 and the picture capturing device 2 when the ambient light brightness is greater than the preset light brightness.

Here, the preset lightness may be 10lux (lux).

Further, the controller 3 is used for directly closing the radar 1 and the picture acquisition device 2 when the system is started and the ambient light brightness is greater than the preset light brightness;

alternatively, the first and second electrodes may be,

and when the system is started and the ambient light brightness is less than the preset light brightness, the radar 1 and the picture acquisition device 2 are started.

Specifically, the controller 3 turns off the alarm signal in two situations, the first situation is that the target object leaves the vehicle, the radar 1 does not detect the target object, and generates a prompt signal, and at this moment, the controller 3 controls the vehicle lamp 4 to stop flashing according to the prompt signal, namely, turns off the alarm signal;

the other is that the car light 4 is flickering, and when the controller 3 detects that the ambient light brightness is higher than the preset light brightness, the car light 4 is controlled to stop flickering, and the radar 1 and the picture collecting device 2 are turned off.

Further, a button 6 is also included;

a button 6 connected to the controller 3 for generating a first activation signal in case of a first activation by a user;

and the controller 3 is used for starting the system according to the first touch signal.

Further, a button 6 for generating a second activation signal in case of a further activation by the user;

and the controller 3 is used for closing the system according to the second touch signal.

Here, a button 6 of the system is arranged in the large screen, when the vehicle is stopped at the roadside, a high bridge or a village without light at night, the button is clicked in the large screen before the vehicle is flamed out, then the vehicle is flamed out, and the vehicle starts the system to give an alarm.

The method specifically comprises the following steps: when a user touches the button 6 for the first time, a first touch signal is generated, and at the moment, the controller 3 starts the system according to the first touch signal; when the user again touches the button 6, a second touch signal is generated, at which point the controller 3 closes the system in accordance with the second touch signal.

Further, the picture collecting device 2 is a high-definition camera.
