Vehicle rollover intelligent protection system and control method thereof

Abstract

The invention discloses a vehicle rollover intelligent protection system and a control method thereof. The vehicle rollover intelligent protection system comprises a judge module and a protection unit; the judge module comprises a sensor unit, a first controller and a signal emitter; the sensor unit comprises a gradienter and a gyroscope; the protection unit comprises a signal receiver, a second controller, a vertical column, an inclined strut, a transverse beam, a buffer device, a first bearing, a second bearing and an adjusting column; the adjusting column comprises a pushing rod, an air cylinder and a power gas generating unit; a gas bag unit comprises a gas bag woven tape, a gas bag gas generator and a plastic sheet; the first controller is electrically connected with the gradienter, the gyroscope and the signal emitter; and the second controller is electrically connected with the signal receiver, the power gas generation unit and the gas bag gas generator. The vehicle rollover intelligent protection system is simple in structure, communication of a vehicle and a guardrail can be achieved through the Internet of Things, the posture of the guardrail is adjusted in the position where impact possibly occurs, and a buffer gas bag is opened to reduce impact applied to the vehicle.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a vehicle rollover safety barrier and a control method thereof. Background technique [0002] With the rapid development of the automobile industry and the national economy, the number of automobiles in my country has ranked among the top in the world. In particular, household SUVs, passenger cars and trucks have become the main means of road transportation in my country. However, these types of vehicles have more passengers or cargo, larger mass and volume, and a higher center of mass. Therefore, compared with small cars, they are more stable. Poor, and once rollover occurs, it will cause serious consequences such as mass casualties and environmental pollution. The guardrail is an effective protective measure to effectively buffer and block the rollover of the vehicle, which will prevent the vehicle from rolling over further and prevent the surrounding vehicles and personnel from b...

AI Technical Summary

Problems solved by technology

Due to the high center of mass and large mass of buses and large trucks, when a rollover occurs, the top of the existing guardrail is often in contact with the body first, which not only cannot protect the body, but will increase the deformation of the body
