Problems solved by technology
[0004] However, when the above method is applied in practice, many problems will be encountered, such as incomplete detection area, false positives, missed negatives, and untimely alarms.
Among them, the most likely to cause trouble is that the above method gives an alarm after an object with a speed exceeding 5km / h enters the target area behind the vehicle, and lacks further identification of the target object, so even if the object is in the same direction as the vehicle The car coming from behind will not collide with the door, but the alarm system will still give an alarm, causing false alarms and causing great inconvenience to users

Embodiment Construction
[0043] The advantages of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0044] see figure 1 , is a schematic diagram of a vehicle door opening warning method according to an embodiment of the present invention. Wherein, the vehicle door opening warning method comprises the following steps:
[0045] S1: Set the first warning area 5 located on the side and rear of the vehicle, and the second warning area 6 located behind the vehicle and within the first warning area 5, and detect the first warning area 5 and the second warning area 6 Whether there is a moving object between the alarm areas 6;
[0046] Such as figure 2 As shown, in this embodiment, the first warning area 5 is located at the rear and side of the vehicle. The first warning area 5 can be an area of any shape and size located on the left, right or rear of the vehicle, or an area of any shape and size located at the rear of the ...

The invention provides a vehicle door opening early warning method, and the method is characterized in that the method comprises the following steps: S1, setting a first alarm area located at the sideand rear of a vehicle, and a second alarm area located at the rear of the vehicle and located in the first alarm area, and detecting whether a moving object exists between the first alarm area and the second alarm area or not; S2, if a moving object exists between the first alarm area and the second alarm area, and the moving object moves towards the vehicle, detecting whether motion parameters of the moving object meet preset motion conditions or not; S3, if the motion parameters of the moving object meet the preset motion conditions, carrying out door opening early warning. The invention further provides door opening early warning equipment. According to the vehicle door opening early warning method, the object which possibly threatens the person getting off the vehicle when the door isopened is alarmed; meanwhile, the object which cannot threaten the vehicle door is not alarmed, and the effect of preventing false alarm is achieved.
Description
technical field [0001] The invention relates to the technical field of vehicle spare parts, in particular to a vehicle door opening warning method and a door opening warning system. Background technique [0002] At present, with the increasing number of cars, in daily life, the contradictions between vehicles, pedestrians and non-motorized vehicles are becoming increasingly acute. When the vehicle is parked on the side of the road, due to negligence, the occupants open the door rashly without seeing whether there are pedestrians or vehicles passing behind, causing pedestrians, bicycles, battery cars, etc. approaching behind the vehicle to collide with the door or people getting on and off the vehicle ACCIDENT. More seriously, this act of opening the door rashly will knock down the above-mentioned persons or vehicles to the motorway, causing major accidents such as rolling over by vehicles coming from behind due to unresponsiveness. [0003] In order to prevent the above-me...
