Vehicle battery pack unloading type anti-collision system and control method thereof

Abstract

The invention relates to the technical field of vehicle collision avoidance, in particular to a vehicle battery pack unloading type collision avoidance system and a control method thereof. When a vehicle is collided in the forward direction, the safety air bag in the middle of the anti-collision cross beam can automatically pop up to push the telescopic cross beam to move towards the vehicle head direction, and the telescopic cross beam drives the rotatable cross beams hinged to the anti-collision longitudinal beams on the two sides to rotate by a certain angle towards the vehicle head direction through sliding block and sliding groove clamping structures at the two ends; through ejection of the safety air bag and rotation of the rotatable cross beam, part of impact force of forward collision can be counteracted, and the influence of the impact force on a vehicle battery pack is reduced; the pressure signal of the head of the vehicle is collected through the pressure sensor, whether the vehicle is collided or not is intelligently judged through the anti-collision system controller, the safety air bag is automatically controlled to pop up, the control logic is simple, the response is rapid, and the anti-collision efficiency of the anti-collision system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of vehicle anti-collision, in particular to a vehicle battery pack unloading type anti-collision system and a control method thereof. Background technique [0002] As a convenient and fast means of transportation, automobiles have entered the daily life of ordinary people. However, with the continuous increase of the number of vehicles, it is inevitable that vehicle collision accidents will occur, resulting in loss of life and property. [0003] In the prior art, vehicle anti-collision lightning is usually used to improve vehicle safety performance. However, due to the current irregular driving behavior and the continuous relaxation of vehicle speed limits, collisions of high-speed vehicles cannot be avoided. [0004] The battery pack of a new energy vehicle is its main power source. Once damaged, the vehicle will directly lose power, resulting in more serious accidents such as rear-end collisions.

However, with the continuous increase of the number of automobiles, it is inevitable that vehicle collision accidents will occur, causing loss of life and property

[0003] In the prior art, automobile anti-collision lightning is usually used to improve vehicle safety performance, but due to the current irregular driving behavior and the continuous relaxation of vehicle speed limits, it is impossible to avoid collisions of high-speed vehicles

[0004] The battery pack of a new energy vehicle is its main power source. Once damaged, the vehicle will lose power directly, causing more serious accidents such as rear-end collisions. The existing vehicle battery pack anti-collision structure design is complex and costly. In the event of a frontal collision, the protection capability of the battery pack is very limited, and the anti-collision efficiency is low
