[0002] The primary purpose of a vehicle door opening warning system is to detect approaching vehicles, pedestrians, or other obstacles when occupants open the door after the vehicle has stopped, and to issue a timely warning or take measures to restrict door opening, thus preventing door-opening collisions. According to statistics, collisions between vehicle doors and oncoming vehicles account for approximately 6% of all traffic accidents caused by drivers and passengers failing to check for oncoming traffic when opening their doors to exit the vehicle. Therefore, door opening warning systems, as an important active safety technology, have received widespread attention and development in recent years.

[0003] Among related technologies, visual, ultrasonic radar, and millimeter-wave radar solutions can be used to identify potential hazards behind a vehicle. When a hazard is detected, audible and visual alarms can be used to alert the driver and passengers.

[0004] However, the current technical solution only warns users of the potential collision risk from the side and rear, and does not fundamentally avoid this risk. In this case, if the user ignores the warning and opens the car door, there is still a risk of collision. Summary of the Invention

[0020] The moving target's speed, the distance between the moving target and the vehicle, and the time it takes for the moving target to reach the vehicle are calculated using millimeter-wave radar.

[0021] Based on the moving speed, the distance, and the time, the pre-collision risk between the moving target and the opening of the vehicle door is determined;

[0022] When there is a pre-collision risk between the vehicle opening its door and the moving target, the risk area where the vehicle is at risk of collision is determined based on the relative position;

[0023] Identify the car doors located within the aforementioned risk area.

[0024] Preferably, the method further includes:

[0025] In response to the presence of the moving target around the vehicle, the millimeter-wave radar is controlled to operate in frequency-modulated continuous wave mode;

[0026] or

[0027] In response to the absence of the moving target around the vehicle or the vehicle being in an energy-saving state, the millimeter-wave radar is controlled to operate in an optimized Doppler mode.

[0051] Figure 6 This is a block diagram of an electronic device structure for a door control method provided in one or more embodiments of the present invention. Detailed Implementation

[0052] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Among the relevant technologies, the mainstream door opening warning function implementation solutions can be roughly divided into three types: visual solutions, ultrasonic radar solutions, and millimeter-wave radar solutions.

[0054] The visual camera solution uses a camera mounted at the rear of the vehicle to capture images from behind, and then uses image processing algorithms to identify and track potentially dangerous moving objects (such as vehicles and pedestrians). When a hazard is detected, it alerts the driver and passengers with an audible and visual alarm. The main drawback of this solution is its sensitivity to environmental conditions; the recognition accuracy drops significantly at night or in poor visibility conditions such as rain or snow. Furthermore, the complex image processing algorithms require substantial computing resources, increasing the data processing load on the vehicle's ECU, and resulting in a longer system response time.

[0055] Ultrasonic solutions typically employ a combination of multiple ultrasonic sensors, calculating the distance to obstacles by measuring the time difference between the emission and return of ultrasonic waves. This approach is relatively inexpensive, but its detection range is short, making it unable to detect rapidly approaching objects at medium to long distances. In complex traffic environments, ultrasonic waves are also susceptible to environmental factors such as temperature and humidity, leading to a decrease in measurement accuracy.

[0056] Millimeter-wave radar solutions can measure the relative distance, azimuth angle, and velocity of targets, accurately determine the specific location of targets in the rear area, and achieve precise door opening warnings. However, the current mainstream millimeter-wave radar operates in a single mode, resulting in high overall power consumption.

[0057] Moreover, the aforementioned door opening warning scheme only alerts users to potential collision risks from the side and rear, and does not provide any feasible solutions to avoid these risks.

[0058] Based on this, this application provides a vehicle door control method, device, storage medium, and vehicle. When a pre-collision risk with other moving targets is detected when opening the vehicle door, the system automatically controls the door's operation to prevent the user from ignoring warnings or accidentally opening the door, thus avoiding collision risks. In particular, when the child locks are engaged in the rear seats, this ensures the safety of rear-seat children by preventing them from being unable to recognize danger using the warning information.

[0059] The following embodiments will further illustrate this application.

[0060] Figure 1 This is a flowchart of a door control method provided by one or more embodiments of the present invention.

[0061] like Figure 1 The door control methods shown include:

[0062] Step S1: In response to the vehicle stopping and the surrounding targets having continuous motion trajectories, determine that there is a moving target around the vehicle and determine the relative position between the moving target and the vehicle.

[0063] By real-time detection of the target's reflection characteristics, motion patterns, and point cloud data, and after processing the data by removing unreasonable data points, the target's trajectory is determined. If the trajectory is continuous, a moving target is confirmed to exist around the vehicle.

[0064] The moving targets can be pedestrians, non-motorized vehicles, and motorized vehicles appearing around the vehicle.

[0065] Further determine the relative position between the moving target and the vehicle. Figure 2 This is a schematic diagram of the relative positions between vehicles provided in a specific embodiment of the present invention, as shown below. Figure 2 As shown, the moving target is located at the left rear of the vehicle, or at the right rear of the vehicle, etc.

[0066] Step S2: When there is a risk of pre-collision between the vehicle door and the moving target, determine the door in the risk area based on the relative position.

[0067] When a moving target is present around the vehicle, the millimeter-wave radar is controlled to accurately calculate the target's speed, the distance between the target and the vehicle, and the time it takes for the target to arrive at the vehicle. If the vehicle opens a door, the pre-collision risk with the moving target at that moment is calculated.

[0068] When there is a risk of pre-collision between a vehicle door and a moving target, the door in the risk area is determined based on the relative position between the moving target and the vehicle.

[0069] Among them, the doors in the risk area can be the left-side doors or the right-side doors of the vehicle, or all of them.

[0070] Step S3: In response to the car door being locked for child safety, obtain the car door status for child safety locking, and control the execution state of child safety locking based on the car door status.

[0071] In this embodiment, if the current vehicle is equipped with a child lock, the sampling zone control mode is used to obtain the door status of the non-child lock doors and the child lock doors respectively.

[0072] If the doors currently in the risk area include those with child locks, then the execution status of the child lock doors is controlled based on their status. Conversely, the execution status of the non-child lock doors is controlled based on their status.

[0073] By linking with the rear child locks, the system can control the child locks on the car doors, better avoiding collision risks and fully protecting the safety of child passengers.

[0074] The millimeter-wave radar described in the above embodiments is positioned on both sides of the rear of the vehicle and can operate in two different modes. One mode is a long-range, high-precision mode, and the other is a short-range, simplified mode. These two modes are suitable for detection needs at different risk levels and distance ranges. Simultaneously, the millimeter-wave radar can also monitor the door opening / closing status, vehicle speed signal, and vehicle attitude information in real time.

[0075] If there are moving targets around the vehicle, the millimeter-wave radar is controlled to operate in frequency-modulated continuous wave mode, employing adaptive frequency scanning technology. The detection range can reach 50-110 meters, and it can accurately calculate the distance, speed, and time of arrival (TTC) of vehicles approaching from behind. If there are no moving targets around the vehicle or the vehicle is in energy-saving mode, the millimeter-wave radar is controlled to operate in optimized Doppler mode, detecting relatively moving targets. Power consumption is reduced to less than 30% of that in frequency-modulated continuous wave mode, while the detection capability of static objects is improved through algorithm optimization.

[0076] This embodiment uses an adaptive detection mechanism to determine whether a moving target is currently present on the vehicle, thereby controlling the operating mode of the millimeter-wave radar. Utilizing a dual-mode millimeter-wave radar, average power consumption can be reduced to 40%-60% of that of a continuous monitoring system while ensuring safety, extending the hardware's lifespan. Furthermore, the millimeter-wave radar is unaffected by light and weather conditions, exhibiting more stable performance.

[0077] The millimeter-wave radar uses the 77-81GHz frequency band, with a horizontal detection angle of -75° to +75°, a vertical detection angle of -10° to +10°, and a maximum detection range of 100 meters.

[0078] Furthermore, once a moving target is identified around the vehicle, the millimeter-wave radar is controlled to operate in frequency-modulated continuous wave mode. The millimeter-wave radar can then calculate the moving target's speed, the distance between the moving target and the vehicle, and the time it takes for the moving target to reach the vehicle. Based on the speed, distance, and time, the pre-collision risk between the moving target and the opening of the vehicle door is determined. When there is a pre-collision risk between the vehicle door and the moving target, the risk zone where the vehicle is at risk of collision is determined based on the relative positions, and the doors within the risk zone are identified.

[0079] In one implementation, if the doors within the risk area include child-locked doors that are closed, the child-locked doors are controlled to lock until a pre-collision risk is detected between the vehicle's open door and a moving target, or until multiple consecutive unlock commands are input by the front-seat occupant within a set time interval, at which point the child-locked doors are controlled to open normally. If the doors within the risk area also include non-child-locked doors, these child-locked doors are controlled to lock until a pre-collision risk is detected between the vehicle's open door and a moving target, or until multiple consecutive unlock commands are input by the non-child-locked door within a set time interval, at which point the non-child-locked doors are controlled to open normally.

[0080] The child lock door closing status is further divided into two situations: the user has not performed the unlocking operation and the user is performing the unlocking operation.

[0081] If the user does not unlock the child lock door at this time, the millimeter-wave radar issues a level one warning, the human-machine interface module reminds the passenger or driver of the danger of getting out of the vehicle, and issues an exit danger warning through the instrument panel or lights. The in-vehicle display shows the child lock door suppression status and displays a child lock door opening simulation animation. This simulation animation includes a pre-collision animation simulating the child lock door opening.

[0082] Figure 3 This is a schematic diagram of the child lock car door opening process provided in a specific embodiment of the present invention. Figure 4 This is a schematic diagram illustrating the interaction of a child lock car door opening signal according to a specific embodiment of the present invention. Figure 3 and Figure 4 As shown, if a user is attempting to unlock the child lock door, and there is a pre-collision risk between the unlocked child lock door and a moving target, the millimeter-wave radar (DOW) sends a Level 1 warning to the Body Control Module (BCM). The BCM controls the door control module to not respond to the door opening operation within time T1 and sends a suppression warning signal to the infotainment system (IVI), reminding the user of the danger of getting out of the vehicle. If the user needs to get out, they should double-click the front door switch. Simultaneously, the IVI drives the speaker to emit an alarm sound, and the ambient lights flash. Within the set time interval (time period T1-T2), regardless of whether the lane change assist warning signal is present, if the user requests to open the door again, the door control module will not suppress it, and the door will open normally. If the user does not perform another door opening operation within T1-T2, the locking function can be triggered again until there is no pre-collision risk between the vehicle and a moving target when the door is opened. A pop-up window on the control instrument panel reminds the user to pay attention to vehicles approaching from behind and displays the suppression status of the child lock door on the in-vehicle display interface, along with a simulated animation of the child lock door opening.

[0083] In another implementation, if the child lock door is in the open state, the current opening angle of the child lock door is used as the maximum opening angle to limit the door's opening angle until there is no risk of pre-collision between the vehicle and a moving target, at which point the door is controlled to open normally. At this time, the millimeter-wave radar issues a level two warning, the human-machine interface module reminds passengers or the driver of the danger of getting out of the vehicle, and simultaneously sounds an alarm and flashes ambient lights. The in-vehicle display shows the child lock door suppression state and displays a simulated animation of the child lock door opening.

[0084] In this embodiment, when a pre-collision risk is identified, the addition of door control function can be used to avoid collision accidents. Different levels of warning and manual priority mechanisms ensure safety while respecting the driver's final decision-making right and improving system acceptance.

[0085] Figure 5 This is a structural diagram of a door control device provided in one or more embodiments of the present invention.

[0086] like Figure 5 The door control device shown includes: a target determination module, a door determination module, and a door control module.

[0088] The door determination module is used to determine the door in the risk area based on the relative position when there is a pre-collision risk between the vehicle door and the moving target.

[0089] The door control module is used to respond to the door being a child lock door, obtain the door status of the child lock door, and control the execution state of the child lock door according to the door status.

[0090] The door control module is used to control the child lock door to perform a locking operation in response to the child lock door being in the closed state; when it is detected that there is no risk of pre-collision between the vehicle door and the moving target, or when it is detected that the front user inputs unlock commands multiple times in a set time interval, it controls the child lock door to open normally.

[0091] The door control module is used to respond to the child lock door being in the open state, and to limit the opening angle of the door to the maximum opening angle of the current child lock door, until there is no risk of pre-collision between the vehicle door and the moving target, and then control the door to open normally.

[0092] The door control module is also used to issue a warning of danger of getting out of the vehicle through instrument or light information, display the suppression state of the child lock door based on the in-vehicle display interface, and display a simulation animation of the child lock door opening; wherein, the simulation animation of the child lock door opening includes a pre-collision animation simulating the opening of the child lock door.

[0093] The door determination module is used to calculate the moving speed of the moving target, the distance between the moving target and the vehicle, and the time it takes for the moving target to reach the vehicle using millimeter-wave radar; based on the moving speed, the distance, and the time, it determines the pre-collision risk of the moving target and the opening of the vehicle door; when there is a pre-collision risk between the vehicle door and the moving target, it determines the risk area where the vehicle has a collision risk based on the relative position; and determines the door located within the risk area.

[0094] The target determination module is configured to control the millimeter-wave radar to operate in frequency-modulated continuous wave mode in response to the presence of the moving target around the vehicle; or, in response to the absence of the moving target around the vehicle or the vehicle being in an energy-saving state, control the millimeter-wave radar to operate in optimized Doppler mode.

[0095] The target determination module is used to detect the reflection characteristics, motion patterns, and point cloud data of the target in real time; determine the motion trajectory of the target based on the reflection characteristics, motion patterns, and point cloud data; and determine that there is a moving target around the vehicle if the motion trajectory is a continuous motion trajectory.
