Problems solved by technology

This solution can prevent problems before they happen. Through the establishment and sharing of the database, the vehicle can give an early warning of the crisis, but it only monitors the danger during the driving process of the vehicle, and does not monitor the possible danger when the occupants get off the vehicle after the vehicle is parked. avoid

Embodiment 1

[0064] For the above-mentioned accidental collision prevention system, this embodiment describes in detail the system composition of the system in conjunction with the specific control system and components on the vehicle, such as figure 1 shown.

[0065] 1—BCM: Corresponding to the above-mentioned control module, on the basis of the existing vehicle BCM, the hardware interface of the four-door glass early warning unit of the car interior warning system is added; the software is modified and adjusted accordingly, and the realization of the functions of exterior warning and interior warning is added .

[0066] 2—Brake light switch: There is no need to make any changes to the brake light switch of the existing vehicle configuration.

[0067] 3—Left projector: The newly added equipment of the vehicle exterior warning system is installed on the left exterior rearview mirror of the vehicle and connected with MP5, which is responsible for projecting the three-dimensional roadblock ...

Embodiment 2

[0089] Combine below figure 1 , figure 2 , Figure 9 , Figure 10 The method for realizing the functions of the system will be described in detail. The system of the present invention is divided into two parts, the exterior prevention system and the interior warning system. The methods for realizing the functions of these two parts will be described below.

[0090] The function realization logic of the off-vehicle prevention system is as follows:

[0091] ①. Ignite and start the vehicle;

[0092] ②. Find the setting function on the central control display, and set the roadblock option of the exterior warning system to the "triangular three-dimensional roadblock" option (there are multiple options to choose from);

[0093] ③. After completing the settings, drive the vehicle on the road normally;

[0094] ④. Step on the brake and start to decelerate;

[0095] ⑤. MP5 detects the braking signal from the CAN network of the vehicle and starts to monitor the vehicle speed;

Abstract

The invention discloses a passenger getting-off door opening accidental collision prevention system and method. The method comprises the process of preventing collision outside the vehicle: after the vehicle is started, setting the form of an early warning roadblock outside the vehicle, when the vehicle speed is less than or equal to a first set value, projecting the set early warning roadblock on the ground behind the side of the vehicle, and reminding moving pedestrians and vehicles behind the side of the vehicle to pay attention to avoiding. By means of the mode of outside-vehicle early warning and inside-vehicle early warning, the risk that passengers open doors and collide with moving sources such as pedestrians, bicycles and electric vehicles behind the vehicle when getting off the vehicle can be effectively avoided, and traffic accidents are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a system and method for accidental collision prevention when a passenger gets off the car and opens a door. Background technique [0002] It is not uncommon for the vehicle to stop and the occupant to get out of the vehicle and open the door, causing bicycles and electric vehicles in the process of driving behind to collide with the door, causing casualties. [0003] CN108583427A discloses a driving safety system for a passenger car. The system is provided with a camera for collecting front and / or rear image information of the vehicle, a radar unit for collecting distance and speed information of surrounding obstacles, and an accelerator sensor for obtaining information on the pedaling depth of the vehicle accelerator. . A brake sensor that obtains information on the depth of the vehicle's brakes, the camera, the radar unit, the throttle sensor, and the brake sens...
