Device and method for preventing children from being trapped in car

Abstract

The invention discloses a device for preventing children from being trapped in a car. The device includes an electronic control unit, a collection unit and a car body control module, wherein the electronic control unit is used for judging state information of a vehicle after the vehicle is turned off, the state information of the vehicle includes a locking state and a non-locking state, wherein the locking state specifically refers to vehicle flameout, car door closing, car window closing and car lock locking, and the non-locking state specifically refers to other states except of the lockingstate; the collection unit is used for collecting audio information in the vehicle when the electronic control unit judges that the vehicle is in the locking state, and sending the audio information to the electronic control unit to analyze whether children are trapped in the vehicle or not; and the car body control module is used for controlling double flash of the vehicle is turned on and whistling when the electronic control unit analyzes that children are trapped in the vehicle, wherein the electronic control unit uses a preset sound model to identify the received audio information to judge whether children are trapped in the vehicle or not. According to the device for preventing children from being trapped in the car, detection is conducted based on existing sensors of the vehicle, the accuracy is high, the implementation cost is low, and popularization is convenient.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a device and method for preventing children from being trapped in a vehicle. Background technique [0002] Automobiles have been popularized in the world at present, and while it brings convenience to the people, there are more and more accidents related to the use of automobiles. Careless parents leave babies and toddlers in cars all over the world. In the hot summer, under the sun exposure, it only takes tens of minutes in a closed car to reach above 60 degrees Celsius. Such an environment will cause heatstroke and even death of children in the car. In recent years, news of children being injured or even killed by being left in a car is often reported. Although such an incident is still a very small probability compared to the number of cars in the existing market, such a tragedy is extremely serious for a family. Heavy, it has important practical significance ...

AI Technical Summary

Problems solved by technology

[0004] 1. The solution is difficult to popularize: before the vehicle leaves the factory, in order to control costs, most businesses will not add a variety of sensors because of the small probability of children being trapped in the car; after the vehicle is used, most users will not because of children being trapped in the car For such a small probability event, special hardware is purchased to monitor children staying in the car

[0005] 2. Too many sensors lead to an increase in system failure points and a decrease in reliability

[0006] 3. Even if it is detected that there is a trapped person in the car, it can only send a notification to the outside and cannot be dealt with, and the people in the car are still in danger
