Intelligent commercial vehicle front-lower part protection device and working method

Abstract

The invention discloses an intelligent commercial vehicle front-lower part protection device and a working method. The method is characterized in that vehicle distance information and vehicle speed information of a vehicle and a front vehicle are continuously acquired through a first control unit, the vehicle distance information and the speed information are compared with a built-in threshold value to control an alarm unit to start and stop, and infrared signals sent by infrared emission equipment are continuously collected through infrared processing equipment; when the vehicle collides, ananti-collision steel beam is deformed, the infrared processing equipment does not receive the infrared signals sent by the infrared emission equipment, and a second control unit starts an air bag to protect pedestrians. According to the device and the method, an active protection function for prompting a driver and a passive protection function for protecting the pedestrian through the air bag arerealized, so that the device can be used for better protecting pedestrians, and is suitable for various accident situations.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to an intelligent commercial vehicle front and lower protection device and a working method. Background technique [0002] Automobile safety performance is one of the important indicators for consumers to purchase automobile products. At present, there are many active safety devices for commercial vehicles, which can reduce or avoid unnecessary traffic accidents. In some unexpected traffic accidents, active safety equipment cannot protect pedestrians and vehicles, and passive safety equipment is required to protect pedestrians and vehicles. The development of a front lower protection device for commercial vehicles with active and passive protection functions will protect pedestrians and vehicles to a greater extent. [0003] The front lower protection device is an important part of the collision safety of commercial vehicles, which can effectively play a passi...

AI Technical Summary

Problems solved by technology

Most of the front and lower protective devices are formed by simple anti-collision beams installed on the front of the vehicle, which can only play a role in buffering the collision force, and cannot predict and warn the occurrence of collision accidents. When a major accident occurs, the accident information cannot be sent out in time. The function is single and the structure is not properly utilized
