Abstract

The invention discloses a car accident escape method and device. The method includes: if it is detected that the vehicle is subjected to an external impact, then detecting the ground pressure on the tires of the vehicle; if the ground pressure is less than a preset ground pressure threshold, then determining whether the vehicle is in a state of falling into water; if the vehicle is in a state of falling into water, Then start the doors and windows, close the safety belt and control the seat to break away from the seat frame. The invention improves the survival rate of escaping in water and avoids unnecessary casualties.

Description

technical field

[0001] The invention relates to the field of automobile safety, in particular to a method and device for escaping from a car accident. Background technique

[0002] Now that there are more and more vehicles, safety accidents will increase during the use of vehicles. When a vehicle has a traffic accident on land, the probability of survival of the driver and passengers is very high. However, once the accident occurs in the water If the driver and passengers are not familiar with water or the driver and passengers are injured, their life safety will be greatly threatened.

[0003] In the prior art, for the escape in water of traffic accidents, only the driver and passengers can escape from the car body and not sink together with the car body. Safe out of danger. Contents of the invention

[0004] In view of this, the object of the present invention is to propose a method and device for escaping from a car accident, so as to improve the survival rate of esca...

Examples

Embodiment 1

[0022] figure 1 It is a schematic flowchart of a method for escaping a car accident provided by Embodiment 1 of the present invention. The method is applicable to the situation that the vehicle falls into the water after the car accident occurs, and the method can be executed by a car accident escape device. The car accident escape device can be realized by software and / or hardware. Such as figure 1 As shown, the method includes:

[0023] Step 110, if it is detected that the vehicle is subjected to an external impact, then detect the ground pressure received by the tires of the vehicle.

[0024] When the pressure sensor detects that the vehicle is subjected to external pressure, compare the external pressure value with the preset impact threshold. When the external pressure value is greater than the preset impact threshold, it is judged that the vehicle is subjected to an external impact, thereby judging that the vehicle has caused a car accident. Detecting whether the veh...

Embodiment 2

[0034] figure 2 It is a schematic flowchart of a method for escaping a car accident provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, if the ground pressure is less than the preset ground pressure threshold, then determining whether the vehicle is in a state of falling into the water is specifically optimized, and the method includes:

[0035] Step 210, if it is detected that the vehicle is subjected to an external impact, then detect the ground pressure received by the tires of the vehicle.

[0036] Step 220, if the ground pressure is less than the preset ground pressure threshold, then determine that the vehicle is in the air state.

[0037] Step 230, determining the length of the vehicle's flight time and the displacement of the vehicle in the vertical direction.

[0038] After the vehicle is vacated, the timer is used to time the vacated time of the vehicle. At the same time, the six-axis acceleration sensor is used to m...

Embodiment 3

[0047] image 3 It is a schematic flowchart of a method for escaping a car accident provided by Embodiment 3 of the present invention. On the basis of the above-mentioned embodiments, a specific optimization is carried out for continuing to determine whether the vehicle is in a state of falling into the water. The method includes:

[0048] Step 310, if it is detected that the vehicle is subjected to an external impact, then detect the ground pressure received by the tires of the vehicle.

[0049] Step 320, if the ground pressure is less than the preset ground pressure threshold, then determine that the vehicle is in the air state.

[0050] Step 330 , determining the length of the vehicle's flight time and the displacement of the vehicle in the vertical direction.

[0051] Step 340, if the length of the flight time is greater than the preset first time length threshold, the direction of the displacement is vertically downward, and the displacement value is greater than the pres...
