Method of actuating external active safety system for vehicle

Abstract

A method of actuating an external active safety system for a vehicle is used for cushioning the impact on the vehicle generated in an accident to effectively reduce injury and death as well as vehicle damage rates after an accident. The present invention mainly installs multiple sets of shock absorption devices (for example, airbags) outside the vehicle, for example, on front and rear bumpers, respectively, and the sets of shock absorption devices is able to function in advance in a segmental manner, so that the shock absorption devices installed outside the vehicle function before and during a collision in a segmental manner, so as to cushion an impact on the vehicle body when impacting or being impacted, and the shock absorption devices have an automatic release function, which, when activated, automatically releases an inflated condition of airbags in a very short time.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]A method of actuating an external active safety system for a vehicle is used for reducing injury and vehicle damage rates in automobile accidents. In particular, the present invention is a method of actuating an external active safety system for a vehicle which can calculate possible collisions in advance and actuate shock absorption devices in a sectional manner, so as to reduce injury and death as well as vehicle damage rates.[0003]2. Related Art[0004]At present, most of the conventional technologies or devices relevant to automobile safety, for example, the relevant technologies such as collision avoidance, airbags, and shock absorption, actuate the shock absorption device only after a collision signal is sensed or detected, so as to achieve the objective of reducing injuries and deaths, namely, the major effects all occur after the collision. For example, in the technical solution disclosed in Taiwanese Patent No. M...

AI Technical Summary

Benefits of technology

The present invention is a method of actuating an external active safety system for a vehicle. The method involves installing multiple sets of shock absorption devices outside the bumpers in advance, and state detection devices in front and rear of the bumpers. The state detection devices can monitor the distance between the vehicle and surrounding physical objects and detect if the vehicle speed is conforming to safety data. If not, an alarm is generated and one of the shock absorption devices is actuated in advance. The method helps to effectively reduce injury and death as well as vehicle damage rates after an accident.

Problems solved by technology

However, the airbag 20 disclosed in this patent is inflated with air after the bumper body 10 is impacted, which fails to provide a preventive function effectively before the vehicle body 30 is impacted.

Also, only one set of airbags 20 is provided, which is insufficient for the effect of reducing injury and death as well as vehicle damage rates after the vehicle body is impacted.

However, although the above technical solution can effectively reduce the force when the vehicle body is impacted, the technical solution has excessively high construction cost and is not economically efficient.
