Problems solved by technology

[0003] Some existing automatic driving technologies use emergency parking to avoid collisions, but this method cannot prevent other vehicles (such as human-driven vehicles or other unmanned vehicles) from losing control and actively crashing into the current self-driving vehicle. Resulting vehicle damage and injuries to occupants of autonomous vehicles
The existing automatic driving technology also detects the collision based on the impact force caused by the collision and triggers the airbag installed inside the car to deploy within hundreds of milliseconds to reduce the damage to the occupants of the car, but this method cannot Avoid damage to the vehicle, and the delay in airbag deployment may not achieve the purpose of protecting the occupants of the vehicle

Embodiment 1

[0038] figure 1 It is a schematic structural diagram of a vehicle anti-collision system provided in Embodiment 1 of the present invention. The vehicle anti-collision system provided in this embodiment can be configured in a car, and is suitable for avoiding or reducing the impact on the car and its occupants when the target object collides with the car. The situation of causing injury is especially applicable to unmanned vehicles, which can improve the safety of unmanned vehicles. In this embodiment, the adaptation of the vehicle anti-collision system to unmanned vehicles is introduced as an example. see figure 1 As shown, the vehicle collision avoidance system specifically includes: an object perception module 110, a control module 120 and an airbag release module 130;

[0039] Wherein, the target perception module 110 includes at least one sensor disposed on the vehicle, such as one or more radars and / or cameras, for sensing target objects around the vehicle. The radar can...

Embodiment 2

[0046] image 3 A schematic structural diagram of a vehicle anti-collision system provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment optimizes the object perception module in the vehicle anti-collision system. The advantage of optimization is that it can The perception range of the target perception module is improved, and the control strategy of the control module is optimized at the same time. The advantage of optimization is that the timeliness and accuracy of vehicle anti-collision can be improved. For details, see image 3 As shown, the vehicle anti-collision system includes:

[0047] Object perception module 310, control module 320 and airbag release module 330;

[0048] Wherein, the target perception module 310 includes an ultrasonic radar set at a first preset position of the vehicle, a millimeter-wave radar set at a second preset position of the vehicle, and a laser radar set at a third preset position...

Embodiment 3

[0062] Figure 5 It is a schematic flowchart of a vehicle anti-collision method provided in Embodiment 3 of the present invention. The method is applied to the vehicle anti-collision system described in the above-mentioned embodiment, and is applicable to situations where there is a risk of collision between a target object and a vehicle. The method can be executed by a vehicle anti-collision device, and the device can be composed of software and hardware, and integrated into a vehicle anti-collision system, which is generally installed in a self-driving car. For details, see Figure 5 As shown, the vehicle anti-collision method includes the following steps:

[0063] Step 510, acquiring data output by at least one sensor set on the vehicle.

[0064] Wherein, the acquisition method may be that the on-board computer actively collects data from at least one sensor of the vehicle based on a specific frequency, or the at least one sensor of the vehicle actively outputs its data t...

Abstract

The invention discloses a vehicle anti-collision system, method, device and equipment, a medium and a vehicle. The system comprises a target sensing module, a control module and an air bag release module; the target sensing module comprises at least one sensor arranged on the vehicle; the control module is used for detecting a target object around the vehicle based on data output by the at least one sensor, calculating the distance and relative speed between the target object and a current vehicle, and sending an air bag opening command to the air bag release module according to a calculationresult; and the air bag release module is used for opening a safe air bag arranged at the outer side of a vehicle body according to the received air bag opening command. Through the above system, thepurpose that on-board passenger casualties and vehicle damage are avoided or reduced is achieved.

Description

technical field [0001] Embodiments of the present invention relate to automatic driving technology, and in particular to a vehicle anti-collision system, method, device, equipment, medium and vehicle. Background technique [0002] Self-driving cars, also known as unmanned cars, rely on technologies such as artificial intelligence, computer vision, radar, global positioning system and high-precision maps to automatically obtain environmental information around the vehicle and make decisions and path planning, so as to achieve complete independence Human-operated autonomous driving. However, due to historical reasons, self-driving cars and cars driven by human drivers will co-drive on the road for a long time in the future. [0003] Some existing automatic driving technologies use emergency parking to avoid collisions, but this method cannot prevent other vehicles (such as human-driven vehicles or other unmanned vehicles) from losing control and actively crashing into the cur...
