The Child Seat Safety System provides drivers (common vehicles) with an alarm and monitoring system for the attachment of safety harnesses and temperature readings for respective child seat occupants within the car. The monitoring component details the attached “status” of said harnesses through indicator lights on the main operator dashboard along with on the system device. Alarm features automatically warn either the driver or surrounding bystanders or emergency personnel of alarm situation including temperature variances, harness disengagement, accident or unattended occupant warnings. The Child Seat Safety System can reduce the risk of small children being injured due to unattached seat belts during accident, braking or collision, and can reduce exposure to unhealthy temperatures either during driving or from extended lengths of time being unattended in a car.

The invention discloses a method for detecting and recognizing the tying of a safety belt of a driver based on interval-maximizing and multi-sample dictionary learning. The method comprises the following steps: treating a driver-containing data-concentrated part of a windshield of a left half car as an image to be processed for input; acquiring a feature vector representation of each image; performing dictionary learning process for a training data set by an interval-maximizing and multi-example manner; respectively training an SVM (Support Vector Machine) multi-classifier for each type in the training data set after clustering to obtain a classifying model; coding the training data through the acquired dictionary; training the classifier through the coded feature vectors; detecting and recognizing an image to be recognized through the trained classifier, so as to determine whether the safety belt is tied from the image to be recognized. According to the recognizing method and system for the safety belt, the safety belt can be simply and easily detected and recognized, the popularization capacity is high, the detection and recognition accuracy is high, and the speed is fast; in addition, the influences of illumination and noise and other adverse factors can be effectively overcome.

The present invention relates to an apparatus for automatically locking and unlocking a vehicle seat belt, which automatically locks and unlocks seat belts of a driver seat and of a passenger seat of a vehicle. The key technical features of the present invention relate to an apparatus comprising: a first housing (10) arranged at an upper portion of a vehicle door; a second housing (20) arranged at a side portion of the vehicle door; a belt-locking bar (40), one end of which is coupled to a hinge portion (30) formed at the center of a connection portion between the first housing (10) and the second housing (20), such that the belt-locking bar (40) rotates between the first housing (10) and the second housing (20), wherein the belt-locking bar (40) has a guide rail portion (45) formed in a lengthwise direction; a movable block (61) slidably coupled to the guide rail portion (45); a retractor (50) arranged at a side surface of a seat (1); a chest protection belt (60), one end of which is connected to the movable block (61) and the other end of which is connected to the retractor (50) such that the other end can be wound by the retractor (50); an abdomen-protecting belt (70), one end of which is connected to the belt-locking bar (40) and the other end of which is connected to the retractor (50), such that the other end can be wound by the retractor (50); and a controller (100) for controlling the rotation of the belt-locking bar (40). According to the present invention, the seat belt is automatically locked upon starting the operation of the engine of the vehicle, even when a driver or a passenger in the vehicle does not manually put on the seat belt, thereby reducing accidents caused by not wearing seat belts.

The invention relates to a multi-node system for reminding a user of buckling a safety belt. The system mainly comprises a host computer processor, cushion node collectors, safety belt node collectors, chairs and a server platform; the host computer processor comprises a node wireless communication mode, a platform wireless communication module, a power supply unit, a velocity judging module, an alarming output module and a host computer MCU; a code collector comprises the cushion node collectors and the safety belt node collectors; the chairs are provided with one cushion node collector and one safety belt node collector separately in a one-to-one corresponding mode. The statistic analysis for unbuckled safety belts and analysis for vehicle attendance rate are achieved. Whether a driver and passengers on a vehicle buckle safety belts or not is supervised, thus the safety awareness of the passengers are improved, and the intelligent monitoring and alarming function of not buckling the safety belts of the chairs is achieved.

The invention provides a detection method for standard wearing of a safety belt, a reminding system for standard wearing of the safety belt and a control method for the reminding system. The detection method is conducted on the basis of the safety belt with marks and a camera, the machine vision and digital picture processing technique is used for obtaining center coordinates of the marks, and the marks are divided into the shoulder strap marks and the waistband marks; and center coordinate point sets of the two types of marks are subjected to line segment fitting, the tightness degree of the safety belt can be judged through the dispersion degree of each type of marks relative to the two sides of a corresponding fitting line, the wearing height condition of the safety belt can be detected through the position of an intersection point of a shoulder strap fitting straight line and a passenger shoulder contour line, and therefore whether the safety belt is worn in a standard manner or not is detected. The method is good in instantaneity and self-adaptive capacity and is still good in detection accuracy when the conditions that the sitting posture of a front-row passenger is changed, the position of a seat is adjusted, and the height and the figure are greatly changed happen. Based on the detection method, the invention further discloses the reminding system for standard wearing of the safety belt and the control method for the reminding system.

The embodiment of the invention provides a method and device for recognizing bad driving behaviors. The method includes the steps of collecting driving data, wherein the driving data includes the speed of a vehicle, the rotating speed of an engine and the state of a safety belt; transmitting the driving data; and analyzing the driving data and recognizing the bad driving behaviors, wherein the baddriving behaviors include the overspeed behavior, the safety belt untired behavior and the idle gear sliding behavior. By means of the method and device for recognizing the bad driving behaviors, bycollecting the driving data in real time, various types of bad driving behaviors of a driver in the driving process can be recognized, the driver is guided to correct the driving behaviors, the basisis provided for insurance companies, vehicle renting companies and other commercial organizations to evaluate the driving behaviors of the driver, and wide applicability is realized.

The invention relates to a safety belt height adjusting device, a safety belt height adjusting method, a seat and a vehicle. The safety belt height adjusting device comprises a fixed part, a movable part and a locking structure, the fixed part is used for being installed on a seat backrest, the movable part is movably connected to the fixed part in the first direction so as to be used for adjusting the height position of a safety belt from a leading-out point of the seat backrest, the locking structure is used for locking the movable part on the fixed part in the first direction, the locking structure comprises a locking piece and an electromagnet, and the locking piece locks or unlocks the movable part by controlling the power-on and power-off of the electromagnet. According to the safety belt height adjusting device, the safety belt can be led out from different height positions of the seat backrest, the tension requirements of passengers with different heights and body types for tying the safety belt are met, the body is prevented from being tightened by the safety belt, and the riding comfort can be improved.
