Embodiment 1

[0034] refer to figure 1 And attached figure 2 , a vehicle door opening anti-collision warning system is specially set for the left front door and the left rear door of the vehicle, including a control device 1, an LED 2, a buzzer 3, a detection radar 7 and a 12V power supply 9, wherein the control device 1 specifically includes MCU (single-chip microcomputer system) 11, vehicle speed signal acquisition circuit 12, door lock master control signal acquisition circuit 13, left front door switch signal acquisition circuit 14, left rear door switch signal acquisition circuit 15, intermediate frequency processing circuit for Doppler radar signal acquisition 16. Acoustic alarm control circuit 18 and visual alarm control circuit 17, the MCU is connected to each circuit, and the vehicle speed signal acquisition circuit 12 is used to collect the vehicle speed signal of the vehicle, and is connected to the vehicle speed sensor of the vehicle. The door lock master control signal acquis...

Embodiment 2

[0038] This embodiment 2 is aimed at the situation that parking is not restricted according to the situation of embodiment 1, then a detection radar needs to be installed on the left and right sides of the rear of the vehicle to comprehensively detect the left and right sides of the rear of the vehicle. In this technical solution, A detection radar is respectively installed at the left and right rear of the vehicle, and the control device also includes a left front door switch signal acquisition circuit, a left rear door switch signal acquisition circuit, a right front door switch signal acquisition circuit and a right rear door switch signal acquisition circuit, respectively connected to The left front door switch device, the left rear door switch device, the right front door switch device and the right rear door switch device of the vehicle, other settings and connection structures are the same as those in the above-mentioned embodiment 1. will double.

Abstract

The invention proposes a vehicle door opening anti-collision warning system and a vehicle door opening anti-collision warning method, the system includes a control device, a visual alarm device, an acoustic alarm device and a detection radar, and the visual alarm device, the acoustic alarm device and the detection radar are connected In the control device, the control device is connected to the door switch device and the door lock master control device of the vehicle at the same time. When the control device learns that the moving target behind the vehicle is approaching the vehicle body through the detection radar, the door lock master control device judges that the door is closed at this time. Whether the lock is in an open state, if so, the control device controls the visual alarm device to report to the police, and simultaneously determines whether the door is in an open state through the door switch device, if so, the control device controls the acoustic alarm device to report to the police. The invention realizes high-precision door opening warning control at the lowest cost and is not affected by environmental factors, greatly reduces the probability of car door collision accidents, and has broad promotion and application prospects.

Description

technical field [0001] The invention belongs to the technical field of automobile active safety, and in particular relates to a vehicle door opening anti-collision warning system and a vehicle door opening anti-collision warning method. Background technique [0002] Vehicle safety has been paid more and more attention by consumers, and active safety technology has played an increasingly prominent role in vehicle safety, not only in the protection of drivers and passengers, but also in the protection of people and non-motorized vehicles in the traffic environment. protection is also being strengthened. Wherein when opening the door with the vehicle, the accident that the bicycle that the car door approaches with the rear, motorcycle collides is particularly prominent, and bicycle, motorcycle driver are caused fatal injury, even death. Its reason is exactly because driver and occupant do not pay attention to observe rear car condition when getting off the car and rush to open...
