High-altitude falling and drowning safety guaranteeing system for automobile and control method thereof

Abstract

The invention provides a high-altitude falling and drowning safety guaranteeing system for an automobile and a control method thereof, which belongs to the technical field of automobiles. A problem of the prior art that the safety is not high is solved. The high-altitude falling and drowning safety guaranteeing system for the automobile comprises a control unit, an immersion sensor, a weightlessness signal sensor, a door lock controller, an automobile window controller and an engine controller, wherein the immersion sensor and the weightlessness signal sensor are connected with an input end of the control unit; and the door lock controller, the automobile window controller and the engine controller are connected with an output end of the control unit. The high-altitude falling and drowning safety guaranteeing control method for the automobile comprises the following steps of exerting the control unit to receive signals transmitted by the weightlessness signal sensor and the immersion sensor and to analyze and judge the received signals; and exerting the control unit to send a control signal to control automobile window closing, automobile door unlocking and engine fuel cutoff when a high-altitude falling accident or a drowning accident is judged. The high-altitude falling and drowning safety guaranteeing system for the automobile and the control method thereof, provided by the invention, is advantaged in that safety measures such as automobile door unlocking, fuel cutoff and so on are automatically executed for passengers on the automobile to escape in case of high-altitude falling and drowning.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a safety guarantee system for automobiles falling from heights and falling into water and a control method thereof, in particular to a safety guarantee system for automobiles falling from heights and falling into water and providing safety protection measures when falling from heights and falling into water, and a control method thereof . Background technique [0002] At present, automobiles have made significant progress in active and passive safety, but only in terms of collision protection, and a new accident form "car falling into water" is gradually concerned and worried by the public, because there is no reasonable solution yet. [0003] Although the probability of a car falling into the water is low, the situation is urgent and dangerous. If the car falls into the water from a high altitude with the window glass open, the car will directly rush to the bottom of the water...

AI Technical Summary

Problems solved by technology

[0003] Although the probability of a car falling into the water is low, the situation is urgent and dangerous. If the car falls into the water from a high altitude with the window glass open, the car will directly rush to the bottom of the water due to the large gravitational potential energy before the car enters the water and the high speed of entering the water. , Under the strong water pressure at the bottom, the water will quickly squeeze into the passenger compartment, which will easily cause the occupants (collectively referred to as all the occupants in the vehicle) to panic. In addition, the occupants may not be able to cope with the impact of the water, and may even choke on the water directly. When the situation in the passenger compartment calms down, there is almost no air supply in the car, and it will face the danger of suffocation. If there are old, weak, sick, disabled or non-swimming passengers in the car, the probability of their escape is very low

[0004] In addition, if the car falls from a high altitude to the land surface, if the window is open, part or all of the human body may be thrown out of the car during the fall or landing process, which will be very dangerous. After the power supply (when the vehicle is an electric vehicle) falls to the ground, the vehicle may be damaged by impact and may cause fire, explosion, or high-voltage leakage

[0005] Aiming at the above-mentioned problems in the process of falling into the water, the existing Chinese patent publication discloses an escape device for a car after falling into the water [Patent No.: ZL201320736960.5]. Safety buckle, although the use of this escape device can achieve a certain escape effect, but the escape device is heavily dependent on the ability and quality of the occupants themselves. It is easy to escape, but if there are some occupants who can't swim, the old, the weak, the sick, and the disabled, then the measure of automatically opening the glass in the escape device will quickly squeeze a large amount of water into the occupant compartment, causing panic and making it too late In addition, the escape device has higher requirements for those who can escape, especially when falling into the water at a high altitude, and cannot protect all occupants in the car, so the safety is not high
