[0045] The present disclosure provides a method for controlling a safety belt according to an early warning method. Figure 1 ,include:

[0046] S101: The motor controller obtains a CAN signal group sent by the sensor system; the CAN signal group includes: a first CAN signal sent by the seat belt sensor, a second CAN signal sent by the buckle sensor, and a third CAN signal sent by the collision sensor;

[0047] S102: The motor controller determines to send an execution control instruction according to the first CAN signal, the second CAN signal and the third CAN signal;

[0048] S103: The motor controller sends an alarm instruction according to the result of executing the control instruction.

[0049] Specifically, in step S102, the motor controller determines to send an execution control instruction according to the first CAN signal, the second CAN signal and the third CAN signal, including:

[0050] Acquire a first CAN signal sent by a seat belt sensor and read the first CAN signal code; determine the seat belt status by reading the first CAN signal code.

[0051] It should be noted that the physical device used in the control method of the pre-tensioned seat belt proposed in the present disclosure includes: a seat belt sensor, a buckle sensor, a collision sensor, a motor controller, a motor and a seat belt buckle alarm device; the set of CAN signals transmitted between the sensors is referred to as a CAN signal group in the present disclosure;

[0052] The seat belt sensor can detect the contraction and tensioning state of the seat belt in real time and transmit it to the motor controller through the CAN signal; the CAN signal sent by the seat belt sensor is the first CAN signal;

[0053] By providing a seat belt sensor, when a car accident occurs and the seat belt needs to be quickly retracted but the car collision sensor fails, the seat belt sensor can determine whether the seat belt needs to be tightened according to the state of the seat belt, thereby reducing the probability of the seat belt not being tightened when the car accident occurs, thereby further improving the practicality and safety of the present invention.

[0054] The buckle sensor can detect the buckle status of the seat belt in real time and transmit it to the motor controller in real time through the CAN signal; the CAN signal sent by the buckle sensor is the second CAN signal; by setting up a buckle sensor and combining the seat belt sensor, collision sensor and buckle sensor through the CAN signal, when the car has an accident and the seat belt needs to be tightened quickly, only the seat belt that is inserted into the buckle will shrink, thereby reducing the chance of injury caused by the shrinkage of the uninserted seat belt.

[0055] The collision sensor can detect the status of the car in real time and transmit it to the motor controller in real time through the CAN signal; the CAN signal sent by the collision sensor is the third CAN signal; the motor controller can control the working status of the motor in real time. When the motor receives the working signal, the motor starts working and drives the seat belt to be quickly retracted for a distance; the motor controller can control the seat belt buckle alarm device in real time. When the seat belt buckle alarm device receives the working signal, the seat belt buckle starts to alarm; the seat belt buckle alarm device is equipped with a flash light and a voice alarm module.

[0056] When the motor works to tighten the seat belt, the flash light on the seat belt buckle starts to flash red, and the voice alarm device warns people to unfasten the seat belt while ensuring safety. Since the emergency tightened seat belt will exert a great force on the human body, the device is set to remind people to unfasten the seat belt to reduce the probability of secondary injury to the human body caused by the seat belt.

[0057] Specifically, the method further includes:

[0058] Acquire a second CAN signal sent by the lock sensor and read the second CAN signal code; determine the lock state by reading the second CAN signal code;

[0059] When the seat belt is in a tensioned state and the buckle is in a locked state, the motor controller sends a motor execution control instruction, and the motor drives the seat belt to be quickly retracted.

[0060] Acquire a third CAN signal sent by the collision sensor and read the third CAN signal code;

[0061] The vehicle collision state is determined by reading the third CAN signal code.

[0062] When the vehicle collision state is a collision state, obtaining a second CAN signal sent by a lock sensor and reading the second CAN signal code; determining the lock state by reading the second CAN signal code;

[0063] When the vehicle collides and the buckle is locked, the motor controller sends a motor execution control instruction, and the motor drives the seat belt to retract quickly.

[0064] Specifically, in step S103, the motor controller sends an alarm instruction according to the result of executing the control instruction, including:

[0065] The motor controller obtains the motor status code and determines the result of the motor execution according to the motor status code;

[0066] When it is identified that the motor status code is that the motor is not working, the motor controller sends a buckle closing alarm instruction to the seat belt buckle alarm device.

[0067] When the motor status code is identified as the motor working safety belt is tightened, the motor controller sends a buckle alarm instruction to the safety belt buckle alarm device;

[0068] Activating the seat belt buckle starts the alarm and the warning signal flashes.

[0069] The above-mentioned seat belt control technical solution is described in detail below in combination with signal control.

[0070] See also Figure 3 The seat belt sensor can detect the contraction and tensioning state of the seat belt in real time, and transmit it to the motor controller through the CAN signal. If the seat belt is not subjected to a large tensile force, the seat belt sensor will always send the seat belt sensor signal "01: Safe" to the motor controller. When the seat belt is suddenly subjected to a large tensile force, the seat belt sensor will send the seat belt sensor signal "00: Dangerous" to the motor controller. In this way, when the car has an accident and the seat belt needs to be quickly recovered but the collision sensor of the car fails, the seat belt sensor can determine whether the seat belt needs to be tightened according to the state of the seat belt, thereby reducing the probability that the seat belt is not tightened when the car has an accident, thereby further improving the practicality and safety of the present invention.

[0071] It should be noted that the CAN signal parameter table defined in this disclosure is:

[0072]

[0073] Specifically, the buckle sensor detects the buckle status of the seat belt in real time and transmits it to the motor controller via the CAN signal in real time.

[0074] If the seat belt is inserted into the seat belt buckle, the buckle sensor sends "00: Locked" in the buckle sensor signal to the motor controller; if the seat belt is not inserted into the seat belt buckle, the buckle sensor sends "01: Unlocked" in the buckle sensor signal to the motor controller;

[0075] The collision sensor detects the vehicle status in real time and transmits it to the motor controller in real time through the CAN signal. When the vehicle is in a non-collision state, the collision sensor always sends the collision signal "01: Safe" to the motor controller. When the vehicle collides, the collision sensor sends the collision signal "00: Crash" to the motor controller.

[0076] The motor controller controls the working state of the motor in real time. The motor controller determines whether the motor is working according to the seat belt sensor signal, collision signal and lock sensor signal.

[0077] When the motor controller receives "00: Dangerous" in the seat belt sensor signal and "00: Locked" in the lock sensor signal, the motor controller sends "00: On" in the motor control signal to the motor. At this time, the motor starts working and drives the seat belt to be quickly retracted for a distance.

[0078] When the motor controller receives "00: Crash" in the collision signal and "00: Locked" in the lock sensor signal, the motor controller sends "00: On" in the motor control signal to the motor. At this time, the motor starts working and drives the seat belt to be quickly retracted for a distance.

[0079] The motor controller does not work when receiving other types of working signals. In this way, when a car accident occurs and the seat belts need to be tightened quickly, only the seat belts inserted in the buckles will retract, thereby reducing the chance of injuries caused by the retraction of uninserted seat belts.

[0080] The motor controller can control the seat belt buckle alarm device in real time. When the motor is not working, the motor controller keeps sending "00: Off" in the buckle alarm signal to the seat belt buckle alarm device, and the seat belt buckle alarm device does not work at this time; when the motor works to tighten the seat belt, the motor controller sends "00: On" in the buckle alarm signal to the seat belt buckle alarm device, and the seat belt buckle starts to alarm, the flash light on the seat belt buckle starts to flash red, and the voice alarm device warns the person to unfasten the seat belt while ensuring safety. Since the seat belt will exert a great force on the human body after emergency tightening, this setting reminds people to unfasten the seat belt to reduce the probability of secondary injury to the human body caused by the seat belt.
