Description

Security device and security method for passengers in vehicle

Technical Field

A security device and a security method for passengers in a vehicle belong to the technical field of vehicle design, and particularly relate to a security device and a security method for passengers in a vehicle.

Background

Some drivers lock passengers in the sealed car intentionally (for example, the driver thinks that the driver can get back soon and lock the child in the car temporarily) or unintentionally (for example, forgets that the driver has the person in the car), and at least dozens of events that the child is forgotten in the sealed car have occurred according to incomplete statistics. Particularly, in summer, passengers (especially children) are locked in a sealed vehicle reversely, and due to high temperature and oxygen deficiency in the vehicle, the heat radiation disease and the oxygen deficiency suffocation are caused after a long time, so that the potential safety hazard of life is caused. Therefore, the invention patent of application No. 2012104908420 discloses an automatic alarm device and method for children danger, the invention patent of application No. 201510449018.4 discloses a passenger car children oxygen deficiency protection device started by car audio, the invention patent of application No. CN201810536512.8 discloses a vehicle fuzzy control children oxygen deficiency protection device and a protection control method, the invention patent of application No. CN201510731546.9 discloses a device and a method for preventing children from being forgotten in a car, and the like, and the invention respectively provides corresponding solutions.

However, the above inventions are all afterward remedies and have not yet achieved the effect of preventing the disease.

And the condition that the driver does not lock the whole car door and close the whole car window and other people enter the car with the door and window not closed and then are locked in the sealed car reversely can happen occasionally, so that the life safety hidden danger is caused.

As the automobile is known to be one of the precious wealth of people, basically people can treasure the precious wealth, so that a driver can close a vehicle door, close a vehicle window and lock the vehicle door after getting off the automobile, and the behaviors are common knowledge behaviors.

The invention is developed based on the common sense behaviors that a driver closes a vehicle door, closes a vehicle window, locks the vehicle door and the like after getting off the vehicle. Moreover, the safety protection technology of the automobile body is better and better at present, such as: when a remote control door closing and window locking key is pressed down or a key-free entering automobile is far away from the automobile body, the automobile window can be automatically closed, the automobile door lock can be automatically locked (after the automobile door is closed), even the automobile door can be automatically closed, and the like. However, the safety factor of passengers in the automobile may be reduced by the advanced automobile body safety protection technology.

Then, it is impossible to prevent the occurrence of a situation where the driver intentionally and unintentionally leaves the passenger in the sealed vehicle, which places the passenger in a dangerous state?

and or, after triggering and starting the driver seat door control unit to further enable the driver seat door to be blocked and closed back, if a passenger is in the vehicle and the passenger does not need to get off the vehicle, but the driver needs to get off the vehicle temporarily, the driver who has got off the vehicle presses the unlocking button, at this time, the processor unit opens the whole vehicle door lock state detection unit to detect whether the door corresponding to the position where the passenger sits is locked or not, and when the door corresponding to the position where the passenger sits is judged to be locked according to the detection information fed back by the whole vehicle door lock state detection unit, the processor unit controls the whole vehicle door lock control unit to enable the door corresponding to the position where the passenger sits to be unlocked, and then the processor unit sends a blocking stopping control instruction to the driver seat door control unit to enable the driver seat door to be closed back,

when the processor unit judges that the door corresponding to the position where the passenger sits is unlocked according to the detection information fed back by the full-vehicle-door-lock state detection unit, the processor unit controls the unlocked door lock not to execute a door locking instruction or lock the door before the vehicle is restarted or the driver seat and the non-driver seat are not occupied, and the processor unit sends a closing instruction to the driver-seat door control unit safety unlocking module until the vehicle is restarted or the driver seat and the non-driver seat are not occupied, so that the driver-seat door control unit safety unlocking module is closed, and then the unlocked door can be locked again;

and/or after the driver seat door control unit is triggered and started to further enable the driver seat door to be blocked and closed back, if passengers are in the vehicle and the passengers do not need to get off the vehicle actually but the drivers need to get off the vehicle temporarily, the drivers who get off the vehicle press the unlocking button, at the moment, the processor unit opens the non-driver seat door state detection unit to detect the opening amplitude of the door corresponding to the sitting position of the passengers, and when the opening amplitude of the door corresponding to the sitting position of the passengers does not accord with the preset amplitude according to the detection information fed back by the whole vehicle door state detection unit, the processor unit controls the non-driver seat door control unit to open the door corresponding to the sitting position of the passengers to a certain preset amplitude and allows the door corresponding to the sitting position of the passengers to continue to be opened at the preset amplitude, and then the processor unit sends a blocking stopping control instruction to the driver seat door control unit to enable the driver seat door to be capable of being opened So as to put the user back into a close,

and when the processor unit judges that the opening amplitude of the door corresponding to the position where the passenger sits meets the preset amplitude according to the detection information fed back by the non-driver seat door state detection unit, the processor unit controls the opened door not to execute a door closing instruction or cannot be closed before the automobile is restarted or the driver seat and the non-driver seat are not occupied, and the processor unit sends a closing instruction to the driver seat door blocking unit manual releasing module until the automobile is restarted or the driver seat and the non-driver seat are not occupied, so that the driver seat door blocking unit manual releasing module is closed, and then the opened door can be closed.

Compared with the prior art, the passenger security device and the passenger security method in the vehicle have the beneficial effects that: since the blocking module of the driver door control unit can prevent the driver door from being closed when the driver is detected to get off before the passenger gets off, the driver door can be closed only when the automobile is restarted (at the moment, the driver gets back to the automobile again) or all the passengers get off or after corresponding passenger safety measures are taken, so that the effect of preventing the driver from getting on the head is achieved, namely the safety guarantee is obtained for the passengers regardless of the fact that the driver does not close the driver door, and the safety accident caused by the passengers not falling into the sealed automobile is guaranteed.
