[0001] The utility model relates to the field of automotive assisted driving safety monitoring, and particularly relates to a vehicle safety driving reminder system and an automobile based on panoramic images. Background Art

[0002] In the prior art, panoramic images provide the status information of the whole vehicle periphery for the vehicle, laying a foundation for the driving safety of the vehicle. For example, a method for controlling the screen switching of an automotive panoramic image system with the patent application number 201510591062.9 includes: entering the 360-degree panoramic image display system, and displaying a view interface and a switching menu on the automotive multimedia display screen; operating an eight-direction knob located on the central tunnel to generate a knob control signal, and applying the knob control signal to the switching menu through the CCP protocol to perform the switching control of the view interface. The panoramic image disclosed in this solution can switch the panoramic image screen by means of a knob.

[0003] Under the prior art, panoramic images are generally only used at low speeds, and the general application scenarios are in situations such as reversing and parking, which can help understand the environment around the vehicle and avoid safety accidents during the reversing or parking process. However, there is a need for panoramic images not only in low-speed situations such as reversing and parking. For example, when a driver is driving, the view behind the B-pillar of the vehicle is a blind spot and cannot be observed. If there is a potential safety hazard on the side during high-speed driving of the vehicle, it is not well prompted, and safety accidents are likely to occur. Moreover, before and after a traffic accident, since traditional driving recorders only record the videos in front of and behind the vehicle, for accidents occurring on the side, video recording cannot be achieved, which affects the subsequent accident judgment. Therefore, the use control and call startup of panoramic images in the prior art cannot meet the actual needs during the driving process of the vehicle. Summary of the Utility Model

Description of the Drawings

[0013] The following briefly describes the content expressed in each drawing of the present invention specification and the marks in the drawings:

[0014] Figure 1 It is the structural schematic diagram of the vehicle safety driving reminder system of the present invention. Detailed Embodiments

[0015] The following is a further detailed description of the specific implementation manners of the present invention by describing the optimal embodiments with reference to the accompanying drawings.

[0016] This embodiment provides a solution that can monitor and remind the safety mechanism of the vehicle's side blind area by using panoramic images. Through this solution, not only can moving objects in the vehicle's side blind area be detected and timely reminders be given, but also the panoramic image system can be started in time to record the video after detecting moving objects in the blind area, realizing the function of side driving record. While improving the safety of the vehicle, the recorded video data can realize the function of driving record, providing basic video reference data for subsequent safety accidents such as collisions and scratches. The specific introduction of the solution is as follows:

[0017] As Figure 1 shown, a vehicle safe driving reminder system based on panoramic images includes a corner millimeter-wave radar, a radar controller, a panoramic image system, and a memory

[0018] The corner millimeter-wave radar is used to detect moving objects approaching from the side of the vehicle, and its output end is connected to the radar controller; the corner millimeter-wave radar adopts a high-precision millimeter-wave radar, with a distance detection range of 0.5m - 60m (short range, accuracy ±0.1m); 0.8m - 210m (medium and long range, accuracy ±0.2m), a speed resolution of 0.5km / h, and a speed measurement accuracy of ±0.15km / h. There are at least two corner millimeter-wave radars, which are respectively arranged on both sides of the vehicle to detect moving objects approaching in the blind areas on both sides of the vehicle.

[0019] The radar controller is the core controller of this system, which mainly realizes data control and processing. Generally, the radar controller of the front and rear radars in the vehicle is reused, or a dedicated radar controller or data processor or IHU host, in-vehicle controller is used to realize the function of the radar controller.

[0020] The output end of the radar controller is connected to the panoramic image system, and is used to drive the opening of the panoramic image system according to the information detected by the corner millimeter-wave radar; the panoramic image system generally includes one or more cameras, and the cameras can be implemented by using wide-angle cameras or fish-eye cameras, etc., and an image processor for controlling the cameras. The image processor is used to drive and control the cameras to collect image information, so as to achieve the purpose of panoramic image acquisition. The panoramic image system is used to take panoramic images of the sides and front and rear of the vehicle. A fish-eye camera or multiple wide-angle cameras can be set to obtain corresponding panoramic image video data through the processing of the image processor, so as to realize the function of panoramic images. Among them, the panoramic image system is connected to the memory, and the memory is used to store the video data captured by the panoramic image system. The panoramic image data collected by the panoramic image system is stored in the memory, thus realizing the data recording function.

[0021] Its working principle is as follows: When the corner millimeter-wave radar detects a moving object approaching the side of the vehicle and the distance from the vehicle is less than the set distance, the radar controller drives the panoramic imaging system to start working, collects video images of the side of the vehicle, and stores them in the memory, thereby realizing the timely data collection and storage of moving objects in the side blind area during the vehicle driving process; when the detected moving object on the side moves away from the vehicle and the distance is greater than the set threshold, the panoramic imaging system is controlled to stop working and stop recording panoramic imaging data, thereby realizing the purpose of automatically turning on and off the panoramic imaging for video shooting of the side of the vehicle.

[0022] In a preferred embodiment of the present application, the output end of the radar controller is connected to the vehicle hazard warning light control module, and the radar controller is used to drive the working state of the vehicle hazard warning light based on the detection information of the corner millimeter-wave. After the corner millimeter-wave radar detects a moving object approaching the vehicle and the distance is less than the set distance threshold, the radar controller drives the vehicle hazard warning light to turn on, and reminds the approaching vehicle to pay attention to safety through the hazard warning light to avoid accidents. The radar controller can directly control the vehicle hazard warning light, or can control the hazard warning light by transmitting a control signal through CAN to a vehicle lamp controller such as the vehicle BCM, thereby achieving the reminder of the approaching vehicle.

[0023] In another preferred embodiment of this solution, the radar controller is connected to the in-vehicle display screen. The radar controller controls the in-vehicle display screen to display the video data collected by the panoramic imaging system according to the distance between the detected moving object and the vehicle. The in-vehicle display screen is generally the central control large screen of the entertainment host. The video data of the approaching vehicle is displayed through the central control large screen to remind the driver, facilitating the driver to make corresponding operations in time, avoiding accidents, improving safety, and achieving the purpose of reminding the driver. When it is detected that a moving object approaches the vehicle and the distance is less than the set threshold, the panoramic imaging image collected by the panoramic imaging system is displayed by driving the central control large screen, thereby realizing the reminder of the driver. The panoramic imaging system can be configured to be connected to the host of the central control large screen to provide corresponding panoramic imaging data.

[0024] The system in this solution starts only when the vehicle is in the starting state and does not work when the vehicle is turned off and parked. Therefore, it is necessary to detect the starting report state of the vehicle, that is, the radar controller is connected to the vehicle starting state module, and the vehicle starting state module is used to collect whether the vehicle is in the ignition starting state or the turned-off and parked state. When the radar controller detects that the vehicle is in the turned-off and parked state, at this time, it controls the corner millimeter-wave radar to be in the sleep state, and the radar controller does not output any signal to the panoramic imaging system. If it is detected that the vehicle is in the starting state, it drives the corner millimeter-wave radar to start working and controls the starting of the panoramic imaging system according to the detected data.

[0025] In a preferred embodiment, the radar controller is connected to the in-vehicle voice system and is used to drive the in-vehicle voice system to issue a corresponding reminder message for a moving object approaching from the side. The in-vehicle voice system is the voice system built into the in-vehicle entertainment IHU host. When the millimeter-wave radar detects that a moving object is approaching the vehicle and the approaching distance is less than the set safety threshold, the radar controller sends a voice reminder to the in-vehicle voice system to remind the user to pay attention, so as to facilitate the user to perform corresponding operations. The reminder message can be "A vehicle is approaching from the side. Please pay attention to safety!", and through the voice reminder, the driver can be better reminded to pay attention. Cooperating with the central control large screen, the reminder can be better realized.

[0026] This solution also provides a vehicle, which includes the vehicle safety driving reminder system based on panoramic imaging in the above embodiment. This vehicle has all the features of the reminder system in the above embodiment, so it has all its advantages and technical advantages.

[0027] In this embodiment, the hardware modules involved include:

[0028] 1. Corner millimeter-wave radar, with a distance detection range of 0.5m - 60m (short range, accuracy ±0.1m); 0.8m - 210m (medium and long range, accuracy ±0.2m), speed resolution of 0.5km / h, and speed measurement accuracy of ±0.15km / h;

[0029] 2. Radar controller (which can be multiplexed with the vehicle's corner millimeter-wave radar data processing controller);

[0030] 3. Panoramic imaging function system.

[0031] Working process and principle: When the vehicle is in motion and there is a moving object (such as a motorcycle, passenger car, or commercial vehicle) approaching from the side, the BSD function is enabled to prompt the user that a vehicle is approaching. At this time, the corner millimeter-wave radar will refresh the vehicle distance at a data output refresh rate of 50ms. When the distance enters the 70cm range, the radar controller will request the vehicle to start the instruction to turn on the hazard indicator lights, indicating that the other vehicle is too close when approaching and there is danger, and trigger the corresponding fish-eye camera screen of the panoramic function to be switched and displayed on the central control large screen to prompt the driver that a vehicle is approaching and pay attention to avoiding danger during driving. At the same time, the panoramic system starts the video recording function; when the distance widens beyond 1.2 meters or the BSD function is released, the video recording function of the panoramic system stops and saves the video in the panoramic system.

[0032] This solution can effectively avoid the risk of collision during vehicle driving. At the same time, there will be data support after the danger occurs, which can solve some unnecessary troubles and avoid unnecessary losses to the vehicle.

[0033] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as various non-substantial improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
