[0048] In order to make the purpose, technical scheme and advantages of the present application clearer, further detailed description of the present application will be given below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The data storage system can store data required to be processed by the server 104. The data storage system can be integrated on the server 104, or placed on a cloud or other network server.

[0050] The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0051] The radar image system control method of the present application includes two parts: a radar alarm method and an alarm information display method.

[0052] The radar alarm method includes collecting information such as whether the vehicle is powered on, whether it is in reverse mode, whether the enable switch is in the on state, vehicle speed, etc., controlling the radar system to work according to the set control method, and outputting alarm information.

[0053] The alarm information display method includes receiving the alarm information output by the radar system, according to the level and direction information of the radar alarm information, combining the working state of the vehicle itself, calling the corresponding camera screen, and displaying the alarm information on the corresponding screen. The system simultaneously issues corresponding alarm sounds according to the alarm information level.

[0054] In one embodiment, as shown in Figure 2 A radar image system control method is provided. Taking the vehicle terminal 102 in Figure 1 as an example, the method includes the following steps:

[0055] Step 202: Detecting obstacles in the detection range based on the ultrasonic radar system, and generating radar alarm information according to the detection result.

[0056] Specifically, the ultrasonic radar system collects key switch signals, reverse switch signals, enable switch signals, vehicle speed signals, etc., for detecting the driving state of the vehicle. The radar alarm information includes obstacle direction information and obstacle distance information in the detection range of the radar detector. The obstacles in the detection range are four (left front, right front, left rear, right rear), and the distance information is divided into three alarm levels (low collision risk, medium collision risk, and high collision risk). According to different system functions, the obstacle information and distance information contained in the alarm information can also be adjusted appropriately. Detecting obstacles in the detection range based on the ultrasonic radar system, and generating radar alarm information containing obstacle direction information and obstacle distance information according to the detection result.

[0057] At step 204, the radar alarm information is detected based on the four-position image system, and a corresponding image picture is called according to the detection result, and the radar alarm information is displayed in the image picture.

[0058] Specifically, after the four-position image system detects the power-on signal of the whole vehicle key, self-detection is performed, and the working state is entered, the radar alarm information is detected, and a corresponding image picture is called according to the detection result of the radar alarm information, and the radar alarm information is displayed in the image picture. Among them, the radar alarm information is transmitted between the four-position image system and the ultrasonic radar system through the CAN bus, and information transmission can also be based on other ways. In this embodiment, the key switch signal, the reverse switch signal, and the enable switch signal are hard-wire signals, and the vehicle speed signal is a CAN bus signal.

[0059] In the above radar image system control method, the ultrasonic radar system detects the obstacles in the detection range, generates radar alarm information according to the detection result, and the four-position image system detects the radar alarm information, and a corresponding image picture is called according to the detection result, and the radar alarm information is displayed in the image picture. Through the cooperation of the four-position image system and the ultrasonic radar system, the coordination of the radar alarm information and the obstacle image picture calling is realized, the cooperation between the ultrasonic radar system and the four-position image system is improved, and the working burden of the driver is reduced.

[0060] In one embodiment, the ultrasonic radar system detects the obstacles in the detection range, and generates radar alarm information according to the detection result, which includes:

[0063] If the reverse signal and the enable switch signal are both invalid, return to re-detect the reverse signal;

[0064] Based on the current vehicle speed, it is judged whether to start the radar sensor, if the radar sensor is started, the radar alarm information is generated according to the detection result of the radar sensor.

[0065] Specifically, Figure 3 The flowchart of the radar alarm information generation step in one embodiment is as follows: Figure 3As shown, when the ultrasonic radar system detects the power-on signal of the car key, the ultrasonic radar system performs self-checking and enters a working state, and when the ultrasonic radar detects that the reverse signal is valid, the current vehicle speed is detected; if the ultrasonic radar system detects that the reverse signal is invalid, the ultrasonic radar system detects the enable switch signal, and if the ultrasonic radar system detects that the enable switch signal is valid, the ultrasonic radar system detects the current vehicle speed. Through detection, if the reverse signal and the enable switch signal are both invalid, return to re-detect the reverse signal, and based on the current vehicle speed, the ultrasonic radar system determines whether to turn on the radar sensor, and if the radar sensor is turned on, radar alarm information is generated according to the detection result of the radar sensor.

[0066] In this embodiment, when the power-on signal of the car key is detected, the ultrasonic radar system performs self-checking and enters a working state, and detects whether the reverse signal is valid; if the reverse signal is valid, the current vehicle speed is detected; if the reverse signal is invalid, the enable switch signal is detected, and if the enable switch signal is valid, the current vehicle speed is detected, and if the reverse signal and the enable switch signal are both invalid, return to re-detect the reverse signal, and finally based on the current vehicle speed, determine whether to turn on the radar sensor, and if the radar sensor is turned on, generate radar alarm information according to the detection result of the radar sensor, which realizes the generation of radar alarm information according to the reverse signal, the enable switch signal and the current vehicle speed, and improves the reliability of radar alarm information generation.

[0070] Specifically, when generating the radar alarm information according to the detection result, the ultrasonic radar system judges whether the current vehicle speed is less than the set vehicle speed, if yes, the radar sensor is turned on, if no, the reverse signal is re-detected; if the radar sensor detects an obstacle in the detection range, the radar alarm information is generated, if no, the reverse signal is re-detected; wherein the radar alarm information includes the obstacle azimuth information and the obstacle distance information in the detection range of the radar detector, the obstacles in the detection range are four (left front, right front, left rear and right rear), and the distance information is divided into three alarm levels (low collision risk, medium collision risk and high collision risk).

[0071] In the embodiment, whether the current vehicle speed is less than the set vehicle speed is judged, if yes, the radar sensor is turned on, if no, the reverse signal is re-detected; if the radar sensor detects an obstacle in the detection range, the radar alarm information is generated, if no, the reverse signal is re-detected, the generation of the radar alarm information is realized through the detection result, and the efficiency of the generation of the radar alarm information is improved.

[0072] In one embodiment, the four-azimuth image system detects the radar alarm information, and according to the detection result, a corresponding image picture is called, including:

[0074] If there are two radar alarm information in front of the vehicle, a second image picture is called;

[0075] If there are no two radar alarm information in front of the vehicle, a first image picture is called;

[0076] When it is detected that the reverse signal is invalid, a steering signal is detected, and a corresponding image picture is called based on the steering signal.

[0077] Specifically, Figure 4 For the flowchart of the image picture calling step in one embodiment, as shown in Figure 4 When the four-azimuth image system works, whether the reverse signal is valid is detected, if yes, the radar alarm information is detected; if there are two radar alarm information in front of the vehicle, a second image picture is called; if there are no two radar alarm information in front of the vehicle, a first image picture is called; when it is detected that the reverse signal is invalid, a steering signal is detected, and a corresponding image picture is called based on the steering signal.

[0078] In the embodiment, when the four-position image system is working, it is detected whether the reverse signal is valid. If the reverse signal is valid, it is detected the radar alarm information, and the corresponding image picture is called according to the radar alarm information. If the reverse signal is invalid, the corresponding image picture is called according to the steering signal, the connection of the radar alarm information and the image picture calling is realized, and the cooperation between the ultrasonic radar system and the four-position image system is improved.

[0079] In one embodiment, when it is detected that the reverse signal is invalid, the steering signal is detected, and the corresponding image picture is called based on the steering signal, which includes:

[0080] When it is detected that the reverse signal is invalid, the steering signal is detected. If the left turn signal is detected, the third image picture is called.

[0081] If the right turn signal is detected, the fourth image picture is called.

[0082] Specifically, when the image picture is called according to the steering signal, when it is detected that the reverse signal is invalid, the steering signal is detected. If the left turn signal is detected, the third image picture is called. If the right turn signal is detected, the fourth image picture is called.

[0083] In the embodiment, when the reverse signal is invalid, the steering signal is detected, and the corresponding image picture is called according to the detected left turn signal or right turn signal, so that the efficiency and accuracy of the image picture calling are improved.

[0084] In one embodiment, when it is detected that the reverse signal is invalid, the steering signal is detected, and the corresponding image picture is called based on the steering signal, which further includes:

[0085] If the reverse signal and the steering signal are not detected, the radar alarm information is detected. If the front radar and the rear radar both have alarm information, the second image picture is called.

[0086] If only the front radar has alarm information, the fifth image picture is called.

[0087] If only the rear radar has alarm information, the first image picture is called.

[0088] If it is detected that the front radar and the rear radar both have no alarm information, no image picture is called.

[0089] Specifically, if the four-position image system does not detect the reverse signal and the steering signal, the radar alarm information is detected. If the front radar and the rear radar both have alarm information, the second image picture is called. If only the front radar has alarm information, the fifth image picture is called. If only the rear radar has alarm information, the first image picture is called. If it is detected that the front radar and the rear radar both have no alarm information, no image picture is called.
