Description

A method and system for safety rescue control of commercial vehicles based on whole vehicle condition monitoring Technical Field

[0001] This invention relates to a commercial vehicle safety rescue control method and system based on whole vehicle status monitoring, and pertains to the field of vehicle safety technology. Background Technology

[0002] With the continuous and rapid growth of commercial vehicle ownership in my country, the number of drivers is also increasing day by day. Various traffic accidents that occur during driving are a major cause of death. Most of these deaths are due to insufficient timely rescue, so rapid, timely and effective rescue is crucial for those being rescued.

[0003] Currently, most commercial vehicle rescue systems on the market do not have the function of real-time monitoring and judgment of the vehicle status. When a vehicle or person is involved in a safety accident, they can only use the button to make a voice call for help. When a person is in a speechless state, it is difficult to report the status of the vehicle and the person in a timely manner.

[0004] Therefore, it is essential to provide an emergency rescue system that can monitor the vehicle status in real time, judge the vehicle status based on the vehicle information, and accurately, promptly and conveniently report help requests to reduce casualties caused by untimely or inaccurate rescue. Summary of the Invention

[0005] To address the aforementioned problems arising from actual vehicle operation, this invention provides a commercial vehicle safety rescue control method and system based on whole-vehicle condition monitoring. The specific technical solution is as follows:

[0006] A control method for a commercial vehicle safety rescue system based on vehicle status monitoring: When the vehicle is powered on, the user activates the safety rescue system via the instrument panel. After activation, the safety rescue system first performs a self-test.

[0007] The system status is determined by CAN signal data. If a fault exists in the relevant system, the fault status of the relevant system is reported to the instrument panel. If there is no fault in the relevant system, the commercial vehicle safety rescue system enters standby mode.

[0008] When the T-BOX terminal receives the safety rescue system activation information, vehicle status judgment information, and GPS location information sent by the ADAS assisted driving controller, it will send the received vehicle status judgment information, GPS location information, safety rescue system activation information, and SOS distress message to the network platform in the form of CAN message.

[0009] After receiving the safety assistance system activation information from the T-BOX terminal, the connected platform will issue an alarm on the platform interface and simultaneously send an SOS distress message to emergency contacts and rescue units via SMS. It will also make a voice call to emergency contacts and rescue units. If the call to emergency contacts and rescue units is unsuccessful, it will make a second call every 15 minutes. After a successful call, the connected platform will transmit the call success status information back to the ADAS driver assistance controller and instrument panel through the T-BOX terminal. The instrument panel will display text and provide a voice prompt indicating that the distress call was successful.

[0010] Preferably, the relevant system states include the SOS button switch state, ADAS driver assistance controller state, BCM body controller state, Electronic Brake Control System (EBS) state, T-BOX terminal state, and connected platform state.

[0011] Preferably, after the commercial vehicle safety rescue system enters standby mode, the commercial vehicle safety rescue system checks whether emergency contact information has been stored. If emergency contact information has been stored, no prompt is made; if emergency contact information has not been stored, the commercial vehicle safety rescue system sends the emergency contact storage status to the instrument panel via CAN message, and the instrument panel prompts the driver to enter emergency contact information via text.

[0012] Preferably, the driver enters emergency contact information in the instrument panel's interface settings. After entering the information, the driver clicks the confirmation button in the interface settings to confirm. After confirmation, the instrument panel periodically sends the emergency contact information to the ADAS driver assistance controller and the T-BOX terminal in the form of CAN messages. The T-BOX terminal sends the emergency contact information to the network platform. After receiving the contact information, the network platform parses and stores it. After storage, the stored information is sent back to the ADAS driver assistance controller through the T-BOX terminal. The ADAS driver assistance controller compares the emergency contact information sent by the instrument panel and the T-BOX terminal. If the emergency contact information matches, it sends a CAN message to the instrument panel to indicate that the emergency contact has been set successfully. If they do not match, it sends an emergency contact setting failure signal to indicate that the emergency contact has been set successfully. If the setting fails, the emergency contact can be reset in the instrument panel.

[0013] Emergency contact information is automatically locked after successful storage. To make changes, you need to click the confirmation button twice to avoid accidental errors in filling in emergency contact information.

[0014] Preferably, once the emergency contact is successfully set, the commercial vehicle safety rescue system enters standby mode and simultaneously monitors the vehicle status information and SOS button trigger information in real time. When the SOS button switch status is received from the instrument panel and the trigger status duration is ≥2s, the ADAS assisted driving controller determines that the driver needs rescue. At this time, the safety rescue system is activated. At the same time, it judges the vehicle status information 5 seconds before and after the SOS button switch trigger status, and then checks whether the automatic emergency braking is activated, whether the lane departure warning is activated, whether the vehicle yaw angle is higher than the threshold, whether the airbag status is deployed, and the driver's facial recognition information status. The acquired vehicle status information is integrated to determine whether the vehicle has collided, deviated, or malfunctioned. Then, the vehicle status judgment information, GPS location information, and safety rescue system activation information are sent to the T-BOX terminal in the form of CAN message.

[0015] When the ADAS driver assistance controller does not receive the SOS button switch status trigger information, but determines that the vehicle has collided, deviated, or malfunctioned based on the status of the automatic emergency braking system, lane departure warning system, vehicle yaw angle threshold, airbag status, driver facial recognition information status, and vehicle forward video monitoring status, it automatically activates the safety rescue system and then sends the vehicle status judgment information, GPS location information, and safety rescue system activation information to the T-BOX terminal in the form of a CAN message.

[0016] Preferably, after the emergency contact is successfully set up for the first time, the safety rescue system prompts the driver to press the SOS button for testing through the instrument panel. When the SOS button is pressed and the safety rescue system is activated, it checks whether the emergency contact has received an SOS distress text message and voice call, thereby verifying whether the safety rescue system is operating normally.

[0017] A commercial vehicle safety rescue system based on whole-vehicle condition monitoring, used to implement any of the above methods, includes:

[0018] The ADAS assisted driving controller collects vehicle status information and driver facial recognition information. Based on the collected vehicle status information and driver facial recognition information, it judges the current vehicle status and driver status. When it receives an SOS trigger information forwarded by the instrument or judges that a collision has occurred, it transmits the judged vehicle status information and driver facial recognition information to the T-BOX terminal in the form of CAN message.

[0019] The T-BOX terminal converts the vehicle status information and driver facial recognition information sent by the ADAS driver assistance controller into SOS distress information, and then transmits it to the network platform.

[0020] The network platform stores the emergency contact information transmitted by the T-BOX terminal. When it receives an SOS distress message from the T-BOX, it sends the SOS distress message to the emergency contact and rescue unit, and simultaneously calls the emergency contact and rescue unit. After the connection is established, it automatically broadcasts the distress location information via voice.

[0021] The SOS button is used to trigger the emergency call system. The SOS button is equipped with a protective cover to prevent accidental touch. The SOS button is connected to the instrument panel via a hard wire. When the driver needs help, pressing the SOS button for more than 2 seconds will activate the safety rescue system.

[0022] The instrument panel is used to input emergency contact information. After input, the emergency contact information is transmitted to the ADAS driver assistance controller. Upon receiving the SOS button trigger information, the SOS button trigger information is transmitted to the ADAS driver assistance controller in the form of a CAN message. At the same time, the safety rescue system information is displayed.

[0023] The Electronic Braking System (EBS) collects the vehicle's yaw angle, lateral acceleration, and longitudinal acceleration values ​​to determine whether the vehicle has deviated from its course or whether a collision has occurred, based on acceleration thresholds.

[0024] Preferably, the vehicle status information includes information on the vehicle's automatic emergency braking system, lane departure warning system, electronic stability control system (ESC), airbag status, GPS location, SOS button trigger information, and vehicle forward video monitoring status.

[0025] The beneficial effects of this invention compared to the prior art are as follows:

[0026] When a person in need presses the SOS button or the system is automatically triggered in the event of a collision, the safety rescue system will accurately and promptly report the assessed vehicle status and location information to the connected platform. The connected platform will then issue a rescue request, reducing casualties caused by untimely or inaccurate rescue. This solves the safety problem that currently common in commercial vehicles on the market do not have a real-time vehicle status monitoring safety rescue system, making it difficult to use a mobile phone to accurately call for help when a vehicle or person is involved in a safety accident, and also preventing the use of any equipment on the vehicle to send a distress signal.

[0027] It has the following advantages: First, it has stronger human-computer interaction, allowing for high flexibility through driver self-entry and timely modification of emergency contact information after changes. Second, it has multiple verification mechanisms, ensuring the complete accuracy of instrument input information and providing real-time alerts to those in need of assistance. Third, the ADAS driver assistance controller assesses the vehicle's status in real time and reports the vehicle status and emergency information, improving rescue effectiveness and saving rescue time. Fourth, it has lower costs, requiring no additional system costs and can be implemented by embedding software algorithms within the existing ADAS driver assistance controller.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] A commercial vehicle safety rescue system based on whole vehicle condition monitoring includes:

[0032] The ADAS (Advanced Driver Assistance System) controller collects vehicle status information and driver facial recognition information. Based on the collected vehicle status information and driver facial recognition information, it judges the current vehicle status and driver status. When it receives an SOS trigger information forwarded by the instrument panel or judges that a collision has occurred, it transmits the judged vehicle status information and driver facial recognition information to the T-BOX terminal in the form of CAN message.

[0033] The T-BOX terminal converts the vehicle status information and driver facial recognition information sent by the ADAS driver assistance controller into SOS distress information, and then transmits it to the network platform.

[0034] The network platform stores the emergency contact information transmitted by the T-BOX terminal. When it receives an SOS distress message from the T-BOX, it sends the SOS distress message to the emergency contact and rescue unit, and simultaneously calls the emergency contact and rescue unit. After the connection is established, it automatically broadcasts the distress location information via voice.

[0035] The SOS button is used to trigger the emergency call system. There is a protective cover above the SOS button to prevent accidental activation. The SOS button is connected to the instrument panel via a hard wire. When the driver needs help, pressing the SOS button for more than 2 seconds will activate the safety rescue system.

[0036] The instrument panel is used to input emergency contact information. After input, the emergency contact information is transmitted to the ADAS driver assistance controller. Upon receiving the SOS button trigger information, the SOS button trigger information is transmitted to the ADAS driver assistance controller in the form of a CAN message. At the same time, the safety rescue system information is displayed.

[0037] The Electronic Braking System (EBS) collects the vehicle's yaw angle, lateral acceleration, and longitudinal acceleration values ​​to determine whether the vehicle has deviated from its course or whether a collision has occurred, based on acceleration thresholds.

[0038] The vehicle status information includes information on the automatic emergency braking system, lane departure warning system, electronic stability control system (ESC), airbag status, GPS location, SOS button trigger information, and forward video monitoring status.

[0039] Example 2

[0040] A control method for a commercial vehicle safety rescue system based on vehicle condition monitoring is provided to control any of the above systems. When the vehicle is powered on, the user activates the safety rescue system via the instrument panel. After activation, the safety rescue system first performs a self-test.

[0041] The system status is determined by CAN signal data. If a fault exists in the relevant system, the fault status of the relevant system is reported to the instrument panel. If there is no fault in the relevant system, the commercial vehicle safety rescue system enters standby mode.

[0042] The relevant system statuses include the SOS button switch status, ADAS driver assistance controller status, BCM body controller status, Electronic Brake Control System (EBS) status, T-BOX terminal status, and connected platform status.

[0043] After the commercial vehicle safety and rescue system enters standby mode, it checks whether emergency contact information has been stored. If emergency contact information has been stored, no prompt will be given; if emergency contact information has not been stored, the commercial vehicle safety and rescue system will send the emergency contact storage status to the instrument panel via CAN message, and the instrument panel will prompt the driver to enter the emergency contact information via text.

[0044] The driver enters emergency contact information in the instrument cluster's interface settings. After entering the information, the driver clicks the confirmation button on the interface settings to confirm. After confirmation, the instrument cluster periodically sends the emergency contact information to the ADAS driver assistance controller and the T-BOX terminal in the form of CAN messages. The T-BOX terminal sends the emergency contact information to the network platform. After receiving the contact information, the network platform parses and stores it. After storage, the stored information is sent back to the ADAS driver assistance controller via the T-BOX terminal. The ADAS driver assistance controller compares the emergency contact information sent by the instrument cluster and the T-BOX terminal. If the emergency contact information matches, it sends a CAN message to the instrument cluster to indicate that the emergency contact has been set successfully. If they do not match, it sends an emergency contact setting failure signal to indicate that the emergency contact has been set successfully. If the setting fails, the emergency contact can be reset in the instrument cluster.

[0045] Emergency contact information is automatically locked after successful storage. To make changes, you need to click the confirmation button twice to avoid accidental errors in filling in emergency contact information.

[0046] Once the emergency contact is successfully set up, the commercial vehicle safety rescue system enters standby mode. Simultaneously, it monitors the vehicle status information and SOS button trigger information in real time. When the SOS button switch status is received from the instrument panel and the trigger status duration is ≥2s, the ADAS driver assistance controller determines that the driver needs assistance. At this time, the safety rescue system is activated. It also judges the vehicle status information 5 seconds before and after the SOS button switch trigger status, and then checks whether the automatic emergency braking is activated, whether the lane departure warning is activated, whether the vehicle yaw angle is higher than the threshold, whether the airbag is deployed, and the driver's facial recognition information status. The acquired vehicle status information is integrated to determine whether the vehicle has collided, deviated, or malfunctioned. Then, the vehicle status judgment information, GPS location information, and safety rescue system activation information are sent to the T-BOX terminal in the form of CAN message.

[0047] When the ADAS driver assistance controller does not receive the SOS button switch status trigger information, but determines that the vehicle has collided, deviated, or malfunctioned based on the status of the automatic emergency braking system, lane departure warning system, vehicle yaw angle threshold, airbag status, driver facial recognition information status, and vehicle forward video monitoring status, it automatically activates the safety rescue system and then sends the vehicle status judgment information, GPS location information, and safety rescue system activation information to the T-BOX terminal in the form of a CAN message.

[0048] When the T-BOX terminal receives the safety rescue system activation information, vehicle status judgment information, and GPS location information sent by the ADAS assisted driving controller, it will send the received vehicle status judgment information, GPS location information, safety rescue system activation information, and SOS distress message to the network platform in the form of CAN message.

[0049] After receiving the safety assistance system activation information from the T-BOX terminal, the connected platform will issue an alarm on the platform interface and simultaneously send an SOS distress message to emergency contacts and rescue units via SMS. It will also make a voice call to emergency contacts and rescue units. If the call to emergency contacts and rescue units is unsuccessful, it will make a second call every 15 minutes. After a successful call, the connected platform will transmit the call success status information back to the ADAS driver assistance controller and instrument panel through the T-BOX terminal. The instrument panel will display text and provide a voice prompt indicating that the distress call was successful.

[0050] After successfully setting up the emergency contact for the first time, the safety rescue system prompts the driver to press the SOS button via the instrument panel to test. When the SOS button is pressed and the safety rescue system is activated, it checks whether the emergency contact has received an SOS distress text message and voice call to verify whether the safety rescue system is functioning properly.
