[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] When parking, most people can observe the road condition information behind the vehicle before getting off and opening the door because the front row of the driver and the front passenger have rearview mirrors. However, for the rear row passengers, there is no rearview mirror, alarm, or other device to facilitate the observation of the road condition behind the vehicle. Even if they can observe through the rear door window, most people are not used to deliberately looking back, so they cannot obtain or understand the road condition behind the vehicle in time. Therefore, when the road condition around the vehicle is not observed in time, the door is suddenly opened, which can easily lead to an accident with the vehicle behind.

[0004] Currently, an inductive device for sensing whether there is an opening action and a detection device for detecting the road condition outside the vehicle can be arranged on each door. However, this requires modification of the vehicle, which is costly. The previous car has a low degree of intelligence, and the in-vehicle control module is mainly concentrated in the key safety positions of the vehicle body and chassis. With the wider application of intelligence, the vehicle domain control integrates the functions of the controller of the chassis, vehicle body, and intelligent driving. The in-vehicle intelligent modules gradually increase. Therefore, it is necessary to solve how to increase the safety of the passengers getting off without increasing the cost through the signal transmission of the existing functional modules. SUMMARY

[0033] Fig. 2 The method flowchart realized by the vehicle door opening safety monitoring system provided for embodiment 1 of the present application is shown in the schematic diagram. DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments of the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. Furthermore, it should be understood that the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0038] Example 1

[0039] like Figs. 1-2 As shown, this embodiment provides a vehicle door opening safety monitoring system, including: a domain controller and a speedometer, electronic interior and exterior rearview mirrors, and a warning device electrically connected to the domain controller;

[0040] The speedometer is used to obtain the vehicle's current speed;

[0041] The electronic interior and exterior rearview mirrors are used to acquire road condition data outside the vehicle;

[0042] The domain controller is configured to determine whether the vehicle has stopped based on its current speed, and when the vehicle stops, to activate the electronic interior and exterior rearview mirrors, detect whether any object has entered within a set range around the vehicle based on road condition data outside the vehicle, and when an object is detected, to keep the door locks locked and activate the warning device until no object enters, at which point the door is unlocked.

[0043] In this embodiment, when the vehicle stops and the driver is about to open the door to get out, the electronic rearview mirror CMS collects road condition data outside the vehicle and transmits it to the domain controller. The domain controller determines whether there is an object entering within a set range around the vehicle based on the real-time road condition information data received outside the vehicle.

[0044] The rear field of view can be displayed on the monitor in the vehicle through the electronic inside and outside rearview mirror CMS, so as to monitor the inside and outside of the vehicle.

[0045] If a high-speed moving object approaches the vehicle when the vehicle is stopped, the door lock is controlled to keep in a state of locking the door to avoid the opening of the door by the person in the vehicle; the double flash is controlled to start to warn the person outside the vehicle to avoid; and the alarm is controlled to start to warn the person in the vehicle not to get off the vehicle, so that the person in the vehicle can find and observe the road condition information behind the vehicle in time.

[0046] Until no object enters, the door lock is re-opened, the double flash and the alarm are turned off under the condition that the road condition is safe.

[0047] Since the front row person can observe the road condition behind the vehicle through the rearview mirror, and the rear row person has no corresponding way, the alarm is installed in the rear row to give real-time voice prompt in the embodiment; or the alarm is not necessarily installed only in the rear row, as long as it can play a prompt warning role.

[0048] As an optional implementation, the set range around the vehicle can be a circular area with the center point of the vehicle as the center, or with the center point of the roof of the vehicle as the center, and the radius being a set distance (such as 2 meters).

[0049] It can be understood that since the opening of the door can cause the object to collide with the door only when the object approaches the vehicle, whether the object approaches the vehicle is detected within the set range.

[0050] It can be understood that the object can be a pedestrian or a vehicle on the actual road.

[0051] In the embodiment, the current speed of the vehicle is detected by a speedometer and sent to the domain controller, and the domain controller judges whether the vehicle is in a stopped state by judging whether the current speed is 0, and when it is judged that the vehicle is in a stopped state, the detection of the road condition behind the vehicle is started to avoid the opening of the door by the person in the vehicle without observing the situation outside the vehicle.

[0052] In the embodiment, the image picture collected by the CMS is transmitted to the display device inside the vehicle body, and a magnified field of view area and the information of the opening of the door are dynamically displayed on the display device, and the information of the opening of the door can also be transmitted to the CMS by the door module ECU on the vehicle, so that the magnified field of view area is displayed on the display device, so that the driver cannot completely master the side road condition information, and the field of view area presented on the display screen is effectively prevented from being limited and affected by the opening of the door.

[0053] Further, the door module ECU is coupled to the CMS, and the door module ECU can directly transmit the vehicle door opening information to the CMS through the communication bus, or the door module ECU is connected to the domain controller to send to the domain controller for display control.

[0054] In the embodiment, the system can not only realize the safety monitoring of the vehicle door opening when the vehicle is parked, but also monitor the driving safety of the vehicle during driving, wherein:

[0055] When the vehicle is driving at a certain speed, the CMS collects data of the road condition in front of the vehicle and the driver state and sends the data to the domain controller ADU;

[0056] The domain controller analyzes the road condition in front of the vehicle, and if a fault is detected in front of the vehicle, the domain controller sends a signal to control the speed reduction until the vehicle stops, and controls the double flash to start to remind the rear vehicle of the accident and pay attention to avoid.

[0057] The domain controller analyzes the driver state, and if an abnormal state of the driver is detected, the domain controller sends a signal to control the speed reduction until the vehicle stops, and controls the double flash to start to remind the rear vehicle of the accident and pay attention to avoid.

[0058] In the embodiment, when the vehicle is driving at a certain speed, the speed detector detects the current speed, and the domain controller judges the current speed, and if the speed exceeds the limited speed, the protection is triggered to control the speed reduction until the limited speed is met.

[0059] It can be understood that the detection of the road condition in front of the vehicle, the driver state, and the vehicle speed adopts a conventional technical means, and only the abnormality can be judged, and the detection method is not specifically described here.

[0060] The above process is mainly for the safety monitoring of the vehicle during driving, and in the case of driving abnormality, the vehicle can be timely reduced in driving to ensure that the vehicle slows down and autonomously drives to the roadside to ensure the safety of the driver and passengers.

[0061] In the embodiment, the analysis of the road condition can be realized by using the existing functional modules in the vehicle, such as the CMS and the ADU. When the vehicle is stationary or driving, the CMS detects the road condition outside the vehicle and the condition inside the vehicle, and transmits the detection information to the domain controller in real time. The domain controller judges the road condition according to the real-time received detection information, and stores the real-time detection information and the judgment result to ensure the safety of the vehicle driving.
