Problems solved by technology

[0004] 1. The applicable collision forms are limited and only effective for a specific working condition, such as frontal collision;
[0005] 2. The tires of the vehicle need to be squeezed and moved back for a certain distance, and only when they touch the trigger device and generate continuous interaction force can they achieve the energy-absorbing effect of rupture, which cannot ensure that all serious collisions can rupture and absorb energy;
[0006] 3. This method can only rupture a certain tire that is squeezed, and the energy absorption is limited;
[0007] 4. This method uses the acupuncture structure to rupture the tire, which may cause the tire to be deflated by mistake due to the beating of the tire, which will cause the danger of vehicle control instability when the vehicle is running
[0008] In summary, in the event of a serious collision accident, the existing tire energy release method has the problem of low safety.

Abstract

The invention discloses a tire energy release method and device. The method comprises the steps that the collision speed and the collision working condition of an accident vehicle are obtained; and when the collision speed is larger than or equal to the preset speed value or the collision working condition meets the preset condition, after it is judged that the state of the accident vehicle is a serious accident state, tires of the accident vehicle are controlled to break and release energy according to the collision working condition. By adopting the embodiment of the invention, the safety of tire energy release can be improved, so that the safety of vehicle driving is further improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method and device for releasing energy from tires. Background technique [0002] In the event of a vehicle collision accident, the collision energy is absorbed by the deformation of the body parts and the failure of the vehicle structure, and is finally transmitted to the passenger compartment, causing damage to the occupants. Therefore, the more energy absorbed by the vehicle due to deformation, failure, etc., the less the occupants in the vehicle will be injured. When a vehicle is severely collided, the tires are squeezed and move backwards, thereby invading the passenger compartment. If the tire ruptures at this time, the energy will be effectively released, reducing the collision energy transmitted to the passenger compartment, thereby reducing the damage to the occupants in the vehicle. [0003] In the prior art, the limitations of the method (such as acupunctur...
