Embodiment 1
[0059] Such as figure 1 As shown, the present embodiment provides a collision avoidance method when the door is opened, which may include the following steps:
[0060] S1: When the door opening signal is received, detect whether there is an obstacle within the first preset range around the door; if yes, go to step S2; if not, go to step S3.
[0061] S2: Send out the highest level alarm signal.
[0062] S3: Detect whether there is an obstacle within the second preset range from the periphery of the car door, if yes, go to step S4, if not, end the process, and just open the car door normally. The second preset range in step S3 is larger than the first preset range in step S1. In specific use, the first preset range can be set to be within 3m from the car door, and the second preset range can be set to be within 15m from the car door, etc., which can be flexibly set according to needs.
[0063] S4: Detect the moving speed and relative distance of the obstacle within the second...
Embodiment 2
[0079] Such as figure 2 As shown, the present embodiment provides an anti-collision device when the door is opened, which may include:
[0080] The control module 1 is configured to send an opening obstacle detection signal to the obstacle detection module 2 when the door opening signal is detected;
[0081] The obstacle detection module 2 is used to start detecting whether there is an obstacle in the first preset range around the door when receiving the opening obstacle detection signal sent by the control module 1;
[0082] If there is an obstacle within the first preset range, then send a first obstacle presence signal to the control module 1;
[0083] If there is no obstacle in the first preset range, the obstacle detection module 2 continues to detect whether there is an obstacle in the second preset range around the door, wherein the second preset range is larger than the first preset range;
[0084] If there is an obstacle in the second preset range, the relative dis...

Abstract
The invention relates to the technical field of automobiles, and provides a car-door-opening collision preventing method and device. When it is detected that obstacles exist within a first preset range around a car door, an alarming signal of the highest level is sent, and safety and timeliness are good; meanwhile, when it is detected that obstacles do not exist in the first preset range around the car door and obstacles exist in a second preset range around the car door, the moving speed and the relative distance of the obstacles in the second preset range relative to the car door start to be detected, and alarming signals of corresponding levels are determined according to the moving speed and the relative distance; the level of the alarming signals is in positive correlation with the moving speed and in inverse correlation with the relative distance. By means of the method and device, whether obstacles exist around or behind the car door is actively detected, corresponding alarming prompts are sent, and the situation that the car door collides with obstacles is avoided to the maximum extent; meanwhile, on the basis of guaranteeing safety, the processing burden of a control module is reduced, and operation efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an anti-collision method and device when a vehicle door is opened. Background technique [0002] With the development of my country's urbanization process, people's living standards continue to improve, and more and more people have their own cars. This has just brought the problem that traffic pressure increases gradually, and parking space is more and more tense. Due to the shortage of parking spaces, in order to be able to park more vehicles in a limited space, the distance between vehicles will inevitably become smaller and smaller when parking, especially the lateral distance between cars; at the same time, due to roads and other reasons, Mixing of people and vehicles is also common. [0003] Nowadays, people's life rhythm is tense. When the passenger or driver opens the door when the car is parked, they often open the door directly, ignoring whether there are obstacle...
