Safe protection system for kid left in car and method thereof

Abstract

The invention provides a safe protection system for a kid left in a car and a method thereof, and belongs to the technical field of vehicles. The invention solves the problem that technological detections in the prior art are not accurate enough. The safe protection system for the kid left in the car comprises a control unit, an acoustic sensor, a motion detector, an air conditioner controller, an engine ECU and a car door lock sensor, wherein the acoustic sensor, the motion detector, the air conditioner controller, the engine ECU and the car door lock sensor are connected with the control unit, and the control unit is further connected with a window lifting mechanism. The safe protection method for the kid in the car comprises the steps of detecting sounds inside the car when the car is in a parking state, and judging whether there is any kid in the car, controlling the engine to ignite and start up and controlling a gear of a transmission to be locked in a P gear or a neutral gear through the engine EPU when the kid is judged to be in the car, controlling the air conditioner to be subjected to refrigeration or heating through the air conditioner controller, controlling a car window to descend to a preset descending height through a car window lifting mechanism if a car door unlocking signal is not received within a preset time. The safe protection system for children staying in car and the method thereof can protect life security of the kid when the kid is forgotten and left inside the car.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a safety protection system and a method for keeping children in a car. Background technique [0002] With the development of the country's economy and the increase of people's income, more and more families have private cars. However, with the rapid development of my country's auto industry, the safety hazards brought by cars cannot be ignored. All major news reports have reported about parents forgetting their children in the car in summer and being heated to death by the rising temperature inside the car. Moreover, due to the high airtightness of the car, even if the child is crying in the car, the pedestrians passing by It is also difficult to perceive the situation in the car, which eventually causes tragedy. If there is a device that can protect children who are forgotten in the car, it will make this kind of painful incident completely eliminated. [0003] In view of th...

AI Technical Summary

Problems solved by technology

[0004] 1. The reliability of safety protection is not strong. In order to attract the attention of people outside the vehicle and achieve timely rescue, it is difficult to achieve the desired effect through the alarm system, because it is difficult for people outside the vehicle to judge the alarm situation of the vehicle. It is difficult to carry out timely rescue

[0005] 2. Although the air-conditioning system can cool or heat up, it is easy to cause hypoxia or carbon monoxide poisoning in a closed environment, and the safety is not high
