Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0030] Figure 4 It is a schematic diagram of the structure of an electronic device for controlling a vehicle-mounted radar provided in an embodiment of the present application. DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0033] On-board radar refers to a radar system installed on a vehicle to detect the vehicle's surroundings. It can help the driver correct the possible deviation between the perception of the surrounding environment and the real environment due to differences in vision height, vision range, and attention allocation during driving. It can also help the driver perceive the environment around the vehicle in the blind spot of vision, and eliminate or reduce the impact of environmental factors such as climate and light on the driver's perception of the vehicle's surroundings. For example, when reversing, when the distance between the vehicle body and an obstacle in the driver's blind spot is too close, the on-board radar can alert the driver by sounding an alarm.

[0034] However, since the timing of the alarm sounded by the on-board radar in different vehicles may be different, and the driver cannot intuitively know the distance between the vehicle and surrounding obstacles based on the alarm sound, the alarm sound emitted by the on-board radar may interfere with the driver, thereby affecting the driver's normal driving operation.

[0035] In view of this, the present application discloses a control scheme for a vehicle-mounted radar, which can not only activate the corresponding vehicle-mounted radar according to different status information in different driving scenarios to perform intelligent assisted driving, but also convert the obstacle information detected by the vehicle-mounted radar into distance information, and intuitively display the distance information that meets the display conditions through the vehicle-mounted display screen, so that the driver can perceive the obstacles around the vehicle more accurately and intuitively.

[0036] Figure 1 is a schematic diagram of an implementation scenario provided by an embodiment of the present application. Figure 1 The implementation scenario provided by the embodiment of the present application may include a vehicle 11 and an obstacle 12. The obstacle 12 may be, for example, a pedestrian, a wall, another nearby vehicle, or any other object that may affect the movement of the vehicle. The following will take a wall as an example. Figure 1 The content shown illustrates the implementation scenario provided by the implementation of this application.

[0037] The vehicle 11 is equipped with an on-board radar system, which may include a control system and an on-board radar. The control system and the on-board radar may be connected by wire or wirelessly, so that the control system may control the on-board radar to transmit radar signals around the vehicle 11, and sense the environment around the vehicle 11 based on the radar signals reflected by obstacles around the vehicle. In some embodiments, the on-board radar may be, for example, an ultrasonic radar, a millimeter-wave radar, a laser radar, an infrared radar, or any other device that can transmit and receive radar signals. The control system may be, for example, a server, or a server cluster consisting of multiple servers, or a cloud computing service center.

[0038] The obstacle 12 may be, for example, a wall located behind the vehicle. When the vehicle 11 approaches the wall, the on-board radar system carried by the vehicle 11 may send out a radar signal, and the radar signal may be reflected after reaching the wall. The on-board radar may determine the distance between the wall and the vehicle 11 based on the radar signal reflected by the wall, and display the distance through the on-board display screen of the vehicle 11.

[0039] Those skilled in the art should understand that the above-mentioned vehicle 11, vehicle-mounted radar system, and the positional relationship between the vehicle 11 and the obstacle 12 are only examples, and other existing or future vehicles and vehicle-mounted radar systems that are applicable to the present application should also be included in the scope of protection of the present application and are included herein by reference.

[0040] Figure 2 is a flow chart of a control method of a vehicle-mounted radar provided in an embodiment of the present application. The method can be executed by a control system installed in a vehicle, for example, and the present application does not limit this aspect. Figure 2 The control method of the vehicle-mounted radar provided in the embodiment of the present application may include the following steps:

[0041] Step S210, obtaining status information indicating a driving scene of the vehicle.

[0042] Exemplarily, a driving scenario refers to an environment and situation related to vehicle driving, which may include, for example, situations and environments such as congested roads, parking, reversing, and nighttime. The acquisition of the status information may be, for example, performed by sensors and / or control systems disposed on the vehicle, or may be acquired from the outside through an external signal connection, and may be any information that can be used to indicate whether the vehicle is in a certain driving scenario. In some embodiments, the status information may be, for example, location information acquired through a GNSS (Global Navigation Satellite System), or road congestion information acquired through an external data connection, etc. This application does not impose any restrictions on the method for acquiring the status information and the form of the status information.

[0043] Step S220: activating the vehicle-mounted radar of the vehicle corresponding to the status information according to the status information.

[0044] As mentioned above, the vehicle-mounted radar can detect obstacle information around the vehicle by transmitting and receiving radar signals, so as to help the driver better perceive the environment around the vehicle. Obstacles can be pedestrians, walls, other nearby vehicles, and any other objects that may affect the movement of the vehicle. The status information can be used to indicate the current driving scene recognition of the vehicle.

[0045] The method for determining the correspondence between the vehicle's status information and the on-board radar can, for example, refer to the following standards: first, identify the vehicle's current driving scene based on the vehicle's status information; then, determine the obstacles that may appear around the vehicle in the scene based on the vehicle's current driving scene; finally, activate the corresponding on-board radar based on the obstacles that may appear around the vehicle, so that the on-board radar transmits radar signals to the obstacles around the vehicle and receives radar signals reflected by the obstacles, so as to detect obstacles that may appear in the vehicle's current driving scene indicated by the vehicle's status information.

[0046] Considering that the relative positional relationship between the obstacle and the vehicle is random, for example, the obstacle may be located in front, behind and / or to the side of the vehicle. In order to more comprehensively detect obstacles around the vehicle, a variety of on-board radars may be provided in the vehicle, so that the driver can perceive the environment around the vehicle in all directions through the on-board radars. In some embodiments, the obstacle information may include, for example, first obstacle information of an obstacle located behind the vehicle, second obstacle information of an obstacle located in front of the vehicle, and / or third obstacle information of an obstacle located to the side of the vehicle. The on-board radar may include, for example, a first radar for detecting the first obstacle information, a second radar for detecting the second obstacle information, and / or a third radar for detecting the third obstacle information.

[0047] It is also considered that in different driving scenarios, the driver's perception of the vehicle's surrounding environment may be affected differently, or there may be different deviations between the perception of the vehicle's surrounding environment and the real environment. In order to reduce energy consumption, the vehicle-mounted radar that helps the driver perceive the vehicle's surrounding environment in the driving scenario can be activated according to the vehicle's current driving scenario. As mentioned above, the state information can be used to identify the vehicle's current driving scenario. In view of this, the vehicle's current driving scenario can be identified according to the state information, and then the vehicle-mounted radar that helps the driver perceive the vehicle's surrounding environment in the driving scenario can be activated.

[0048] The current driving scene of the vehicle may be, for example, a reversing scene. When the vehicle is in a reversing scene, obstacles behind and / or to the side of the vehicle may be located in the driver's blind spot, making it impossible for the driver to accurately perceive the environment behind and / or to the side of the vehicle. In view of this, the radar that helps the driver perceive the surrounding environment of the vehicle in the scene can be activated by the state information related to the vehicle being in the reversing scene. In some embodiments, the state information for indicating the current driving scene of the vehicle may include, for example, gear information for indicating the gear position of the vehicle, and the vehicle-mounted radar of the vehicle corresponding to the state information is activated according to the state information of the vehicle, for example, it may include: in response to the gear information being the reversing gear position of the vehicle, activating the first radar and / or the third radar corresponding to the gear information. Among them, the gear information can be used to identify whether the vehicle is currently in a reversing scene. When the gear position of the vehicle indicated by the gear information of the vehicle is the reversing gear position, the current driving scene of the vehicle can be identified as a reversing scene, and then the first radar and / or the third radar are activated according to the gear information to detect the rear / or side of the vehicle.

[0049] The current driving scene of the vehicle may also be a congested road scene. When the vehicle is in a congested road scene, the distance between the vehicle and other vehicles on the road may be relatively close, so that the driver cannot accurately perceive the distance between the vehicle and other vehicles on the road. In view of this, the radar that helps the driver perceive the surrounding environment of the vehicle in this scene can be activated by the state information related to the vehicle being in a congested road scene. In some embodiments, the state information for indicating the current driving scene of the vehicle may include, for example, vehicle speed information for indicating the vehicle speed, and the vehicle-mounted radar corresponding to the state information is activated according to the state information, for example, it may include: in response to the vehicle speed information being lower than the vehicle speed threshold, activating the second radar and / or the third radar corresponding to the vehicle speed information. Among them, the vehicle speed information can be used to identify whether the vehicle is currently in a congested road scene. When the vehicle speed indicated by the vehicle speed information is lower than the vehicle speed threshold, the current driving scene of the vehicle can be identified as a congested road scene, and then the second radar and / or the third radar are activated according to the vehicle speed information to detect the front and / or side of the vehicle.

[0050] In other embodiments, when the speed indicated by the vehicle speed information is lower than the speed threshold, road traffic information indicating whether the road section currently located by the vehicle is congested may be further obtained to determine whether the vehicle is currently in a congested road section. In some embodiments, the road traffic information may be, for example, first road traffic information obtained through a GNSS (Global Navigation Satellite System), or second road traffic information obtained through a data connection with an external server system, or third road traffic information obtained through other sensors disposed on the vehicle.

[0051] In some other embodiments, the third-party traffic information obtained by other sensors installed on the vehicle may be, for example, information about other vehicles on the road, traffic light information, etc. obtained by sensors installed on the vehicle.

[0052] The current driving scene of the vehicle may also be a startup scene. When the vehicle is in the startup scene, obstacles in front of, behind and / or on the side of the vehicle may be located in the driver's blind spot, making it impossible for the driver to accurately perceive the environment behind and / or on the side of the vehicle. In view of this, the radar that helps the driver perceive the surrounding environment of the vehicle in the scene can be activated by the state information related to the vehicle in the startup scene. In some embodiments, the state information may, for example, include startup information for indicating that the vehicle is started, and the vehicle-mounted radar of the vehicle corresponding to the state information is activated according to the state information, for example, it may include: in response to detecting the startup information, activating the first radar, the second radar and / or the third radar corresponding to the startup information. Among them, the startup information can be used to identify whether the vehicle is currently in the startup scene, so that the vehicle activates the first radar, the second radar and / or the third radar according to the startup information to detect the rear, front and / or side of the vehicle. The startup information may, for example, be the key information, gear information and / or vehicle speed information of the vehicle, and the present application does not impose any restrictions in this regard.

[0053] As mentioned above, the vehicle-mounted radars can work independently or together. For example, when the vehicle is in a reversing scenario, the first radar and / or the third radar can be activated based on whether there are obstacles behind and / or to the side of the vehicle; or when the vehicle is in a congested road scenario, the second radar and / or the third radar can be activated based on the relative position relationship between the vehicle and other vehicles on the road; or when the vehicle is in a starting scenario, the first radar, the second radar and / or the third radar can be activated based on whether there are obstacles behind, in front of, and / or to the side of the vehicle.

[0054] Those skilled in the art should understand that different on-board radars activated in different driving scenarios to help the driver perceive the vehicle's surrounding environment, that is, the correspondence between the vehicle's status information and the on-board radar, can be adjusted according to actual application conditions, and this application does not impose any restrictions in this regard.

[0055] Step S230, detecting obstacle information around the vehicle through a vehicle-mounted radar corresponding to the status information.

[0056] As mentioned above, obstacles can be, for example, pedestrians, walls, other nearby vehicles, and any other objects that may affect the movement of the vehicle; similarly, obstacle information can also be information about pedestrians, walls, other nearby vehicles, and any other objects that may affect the movement of the vehicle. In some embodiments, obstacle information can be, for example, time interval information between the time of transmitting and receiving a radar signal obtained by an on-board radar, which indicates the distance, relative position, shape, and speed between the vehicle and surrounding obstacles, the angle information of the radar signal, or point cloud data of the radar signal, etc. The present application does not impose any restrictions in this regard. Different on-board radars can be used to detect obstacle information at different locations around the vehicle, and different on-board radars can be activated according to the status information of the vehicle in different driving scenarios, so that the embodiments of the present application can more intelligently assist the driver in driving operations.

[0057] As described above, it is possible to identify whether the vehicle is in a reversing scenario based on the gear information of the vehicle. When the vehicle is in a reversing scenario, the vehicle-mounted radar to be activated can also be selected based on the relative position relationship between the vehicle and the surrounding obstacles to detect obstacles in different directions when the vehicle is reversing. In view of this, in some embodiments, the obstacle information around the vehicle is detected by the vehicle-mounted radar corresponding to the vehicle status information, for example, including: detecting the first obstacle information by the first radar corresponding to the gear information of the vehicle, and / or detecting the third obstacle information by the third radar corresponding to the gear information of the vehicle.

[0058] As mentioned above, it is possible to identify whether the vehicle is in a congested road scene based on the vehicle speed. When the vehicle is in a congested road scene, the vehicle-mounted radar to be activated can be selected based on the relative position relationship between the vehicle and other vehicles on the road to detect other vehicles at different locations on the road when the vehicle is in a congested road scene. In view of this, in some embodiments, the obstacle information around the vehicle is detected by the vehicle-mounted radar corresponding to the state information, for example, including: detecting the second obstacle information by the second radar corresponding to the vehicle speed information, and / or detecting the third obstacle information by the third radar.

[0059] Similarly, when the vehicle is in the startup scene, the vehicle-mounted radar to be activated can be selected according to the relative position relationship between the vehicle and the surrounding obstacles to detect obstacles in different directions when the vehicle is reversing. In view of this, in some embodiments, the obstacle information around the vehicle is detected by the vehicle-mounted radar corresponding to the state information, for example, it can include: detecting the first obstacle information by the first radar corresponding to the startup information, detecting the second obstacle information by the second radar, and / or detecting the third obstacle information by the third radar.

[0060] Step S240, generating distance information according to the obstacle information, and displaying the distance information that meets the display conditions through the vehicle's onboard display screen.

[0061] Among them, the distance information can be used for but not limited to indicating the distance between the vehicle and the surrounding obstacles, so that the driver can have a more intuitive understanding of the distance between the vehicle and the surrounding obstacles based on the distance information prompted on the vehicle display screen. As mentioned above, the obstacle information can be, for example, the time interval information between the time of transmitting and receiving the radar signal. In view of this, in some embodiments, the distance information used to indicate the distance between the vehicle and the surrounding obstacles can be determined based on the time interval information between the time of transmitting and receiving the radar signal, and the speed information of the radar signal. Among them, the speed information of the radar signal is used to indicate the speed of the radar signal, and the speed of the radar signal is the speed of light.

[0062] The display condition can be used to filter the distance information so that only the distance information that is necessary to remind the driver is displayed on the vehicle display screen to avoid distracting the driver's attention and reduce the time occupied by the vehicle display screen. The vehicle display screen can be, for example, a screen device inside the vehicle for displaying various information.

[0063] Considering that in most driving scenarios, it may be difficult for the driver to perceive obstacles behind the vehicle, which in turn affects the driver's operation in the reversing scenario. In view of this, when the vehicle is in a reversing scenario, the first distance information of the first obstacle information behind the vehicle can be prompted through the display screen to assist the driver to better complete the reversing operation. In some embodiments, the display condition may, for example, include a first display condition for indicating that the vehicle-mounted radar is the first radar, and the distance information that meets the display condition is displayed through the vehicle-mounted display screen of the vehicle, for example, it may include: if the vehicle-mounted radar is the first radar, the first distance information corresponding to the first obstacle information detected by the first radar is prompted through the vehicle-mounted display screen of the vehicle.

[0064] It is also considered that in most driving scenarios, only when the distance between the obstacle in front of and / or on the side of the vehicle and the vehicle is small will it affect the driver's perception of the front and / or obstacles, thereby affecting the driver's normal driving operation. In view of this, when there are obstacles in front of and / or on the side of the vehicle, the second obstacle information and / or the third obstacle information in front and / or on the side can be screened by display conditions to avoid unnecessary occupation of the vehicle display screen. In view of this, in some embodiments, the display condition includes a second display condition for indicating that the second distance information corresponding to the second obstacle information and / or the third distance information corresponding to the third obstacle information is less than the distance threshold, and the distance information that meets the display condition is displayed through the vehicle display screen, including: if the second distance information and / or the third distance information is less than the distance threshold, the second distance information and / or the third distance information is prompted through the vehicle display screen. Among them, the distance thresholds corresponding to the second distance information and the third distance information can be the same or different, and this application does not impose any restrictions in this regard.

[0065] Considering that the display screen inside the vehicle usually has a specific function, in order to avoid the interference of distance information on the normal functions of different vehicle-mounted display screens, a display screen can be set on the interior rearview mirror. In view of this, in some embodiments, the vehicle-mounted display screen includes a first display screen set in the interior rearview mirror of the vehicle.
