Problems solved by technology

At the same time, this design also has certain potential safety hazards and inconvenience. If some accidents occur in the car, the internal power of the car will be cut off, which will further affect the driver to open the child safety lock of the car through the control system. Able to open the door and escape through someone outside the car
In addition, when the child safety lock is turned on in adverse weather such as rain and snow, it will be a lot of inconvenience to open the door through the door handle outside the car or roll down the window and extend the hand out of the window to open the door.
In addition, many car owners do not know the function and purpose of the child safety lock of the car. Once the child safety lock is locked without knowing it, causing other doors to be unable to be opened inside, they will think that the door handle is faulty and will drive the car. Entering the 4S shop for repairs, resulting in unnecessary travel

Embodiment 1

[0035] A car child safety lock control system, such as figure 1 Shown: including image recognition module, communication module, signal processing module, MCU control module, car child safety lock and spare battery module, described image recognition module and communication module are connected with signal processing module respectively, described MCU control module is connected with respectively Image recognition module, communication module, signal processing module, car child safety lock and backup battery module are connected.

[0036] The image recognition module is used to perform face feature recognition on the in-vehicle images collected by the connected camera and send the face feature recognition result to the signal processing module.

[0037] Specifically: the image recognition module is connected to the camera, and the features of the in-car images collected by the camera are extracted, and then the extracted feature information is matched with the reference info...

Embodiment 2

[0051] A kind of car child safety lock control method, such as figure 2 shown, including the following steps:

[0052] Obtain the status request signal of the car child safety lock and the collision signal of the airbag controller.

[0053] Collect images of occupants in the car and perform facial feature recognition on them to determine whether there are children in the car;

[0054] Specifically, it includes: extracting features from the acquired images inside the car, and performing matching calculation and analysis on the extracted feature information with the reference information in the internal database to determine whether there are children in the car.

[0055] Change the state of the child safety lock of the car according to the collision signal of the airbag controller, the result of face feature recognition and the state request signal of the child safety lock of the car.

[0056] Specifically include:

[0057] Determine whether the collision signal of the airb...

Abstract

The invention relates to a control system and method for an automobile child safety lock. The control system comprises an image recognition module, a communication module, a signal processing module,a MCU control module and the automobile child safety lock, wherein the image recognition module and the communication module are respectively connected with the signal processing module, and the MCU control module is connected with the image recognition module, the communication module, the signal processing module and the automobile child safety lock respectively. According to the control systemand method, a camera is used to recognize facial features in an automobile through the image recognition module, the recognized child information is used as a basis for locking, and the recognized adult information is used as a basis for unlocking. Meanwhile, the open and close state information of the automobile child safety lock is obtained by interaction of an automobile body ECU and a CAN bus,and finally, the MCU control module sends relevant commands according to the information recognized by the image recognition module and the open and close state information of the automobile child safety lock, so that the control is more convenient and intelligent.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automobile child safety lock control system and method. Background technique [0002] The child safety lock in the car is a lock designed to prevent the car from being accidentally opened by children during driving. At this stage, child safety locks are basically based on mechanical structures. If the child safety lock is locked, except for the driver's door, other doors cannot be opened inside the car, and other doors can only be opened through the door handle outside the car. The original intention of this design is to avoid safety accidents caused by children unintentionally opening the car door while the car is running. At the same time, this design also has certain potential safety hazards and inconvenience. If some accidents occur in the car, the internal power of the car will be cut off, which will further affect the driver to open the child safety lock of t...
