The invention CN207045234 relates to a technical field of motor vehicle safety implies in particular that a car be parked in the seat and be occupied by an alarm device. Comprising a plurality of sensors used for attachment to the seat, these small sensors are all connected to one system, this system is used to receive the sensor's collection signal, alarm, to prevent children from being forgotten. The document CN208232991 describes an on-board alarm system in a car, comprises a processing unit, an information collection module, an alarm circuit, a GPRS module, makes it possible to activate the window using an emergency drive motor in case there is a forgotten child in the car.

CN206202030: This invention describes a safety seat monitoring device, comprising a transmitter and a receiver; The transmitter is installed on a safety seat, uses a pressure sensor to detect if there is a person in the seat, and sends a signal to the receiver via a Bluetooth connection to detect the presence of a child in the car .

Document CN206058467 describes a vehicle air conditioning and window control system for controlling air conditioners and opening windows, mobile phone terminals, receiving information about people in the car sent by the 4G intelligent control system of the vehicle; avoid forgetting the sleeping child or the elderly in the car due to driver negligence.

The invention CN106965764 describes a child seat detection and anti-forgetting system and method for children. The system includes a seat detection unit used to detect whether a child exists in a child safety seat or not, a vehicle extinction detection unit used to detect whether a vehicle stops operating or not and a remote alarm unit used for a remote alarm.

The invention US2017182938 prevents one of these situations from occurring because it warns drivers that the child is in the car each time he opens the car door. This alarm system activates even when the ignition switch is “Off”.

US9189943 relates to a child safety seat with alarm for use in the transport of infants in vehicles. The child safety seat with alarm has particular utility in notifying the driver of a vehicle that an infant is in his seat inside the vehicle when the driver leaves the vehicle.

The invention US2007268119A1 describes a child safety system which detects if a child is left alone in an automobile and alerts others. One implementation includes a weight sensor for sensing the weight of a child applied to an infant car seat, a transmitter for transmitting, to an alarm device, an alert signal when a child is in. the seat, and a driver's door switch. The alarm device generates an alarm signal (for example, a loud siren sound) if an infant is in the seat after the door switch indicates that the driver has left the car.

The invention WO2017065761A1 describes a child car seat alarm system for signaling if a child has been left unattended in a vehicle Locked. The system comprises: a weight detection sensor, said child activating weight detection sensor is positioned in a child safety seat; a power source for operating said child car seat alarm system; and a wireless alert unit, said unit being connected through said system by means of Bluetooth technology.

3- The invention EP3154037A1 describes a child car seat containing an alarm system, which alerts the entourage if a child is left in a vehicle, when the driver leaves the vehicle and the child is left inside.

Disadvantages of the cited inventions:

- Inventions that are based on smartphones do not solve the unintentional problem of forgetting, because the possibility of forgetting your child is much smaller than the possibility of forgetting your smartphone or the alarm system itself .

- Connected seats are not always practical because sometimes children are not installed in their seats either voluntarily or involuntarily.

- Intervention to save a child after forgetting, and not before, is not a good solution, so it is better to eliminate the risk of forgetting from the start.

Advantages compared to the previous state:

Our invention compared to the prior state has the following advantages:

• High reliability;

• High efficiency;

• Great security.

4- Disclosure of the invention:

In recent years, the number of children who die locked in cars has tended to increase dramatically. The vast majority of these tragedies happen because the parents or responsible adults forget the child in the car.

Many people blame it on the irresponsibility of parents who do not pay attention to their offspring. But this sad mistake can be made by any human being who has a brain, who has a routine, and who is faced with a stressful situation. It does not matter your gender, your age, your education or your intellectual level. Our invention describes an intelligent system to help drivers remember their children or pets in a locked car, consisting of the parts (Fig. 1):

• Motion and presence detection sensors (1), which will indicate whether there is anyone in the locked car;

• An information processing system (2), which will combine the information indicating the presence or not of a body in the car;

• An intervention and warning system (3) to alert the driver of the situation.

6- Detailed description of the embodiment of the invention:

Our invention describes an intelligent system to help drivers not to leave or forget their children or animals in a locked car on their own.

According to FIG. 1, the system which is the subject of the invention is composed of the following parts:

• Motion and presence detection sensors (1), which will indicate whether there is someone on board or on the seats of the car when the driver leaves his seat, they are either integrated in all the seats of the car. the car either placed under the seat covers or integrated into the seat covers. These sensors send different signals depending on the presence of the passengers, For example:

> an "A" type signal, if the sensor detects a mass greater than the mass of a conventional object which may be in a car (baby seat, schoolbag, suitcase, etc.) for example 5 kg, but less than the average mass of a small child, for example 30 kg: this type of signal indicates the presence of a child or animal in the car.

> a type “B” signal, if the sensor detects a mass greater than the average mass of a small child, for example 30 kg: this type of signal indicates the absence of children or animals on board.

> a “C” type signal, if the sensors detect movement inside the car: this type of signal indicates the presence of someone in the car. • An information processing system (2), which will combine the signals from the sensors indicating the presence or absence of a body in the car then send the corresponding signal to the intervention and warning system (3).

• An intervention and warning system (3), which will authorize or not the closing of the doors and trigger or not an audible signal depending on the situation. The intervention and warning system is linked to the door locking system and operated by the remote control of the door locking system. If there are no children or animals in the car, the intervention and warning system allows the doors to be closed.
