[0053] See Figure 1 The flowchart of a vehicle collision safety control method according to an embodiment of this application is shown.

[0054] like Figure 1 As shown, according to a first aspect of the embodiments of this application, a vehicle collision safety control method is provided, including but not limited to steps S101 to S103:

[0055] Step S101. During the collision event, acquire the collision speed of the vehicle and the changes in various attribute information of the hydrogen supply system, wherein the attribute information is information that affects the sealing properties of the hydrogen supply system;

[0056] Step S102. Determine the expected damage level of the hydrogen supply system based on the vehicle's collision speed and a preset mapping relationship;

[0057] Step S103. Execute the corresponding collision safety control strategy based on the expected damage level of the hydrogen supply system and the changes in each of the attribute information.

[0058] Based on the above disclosure, the embodiments of this application acquire the collision speed of the vehicle and the changes in various attribute information of the hydrogen supply system during a collision event; determine the expected damage level of the hydrogen supply system based on the vehicle collision speed, and combine the changes in the attribute information of the hydrogen supply system to obtain a collision safety control strategy that matches the expected damage level and the changes in attribute information. This enables a collision control strategy that matches the severity of the collision event, avoids misjudgment, and improves the safety performance of vehicle operation.

[0059] In some implementations, the vehicle collision safety control method in this application embodiment can be implemented by the vehicle's existing ECU (Electronic Control Unit) controller, which can be located inside the vehicle compartment.

[0060] In step S101, when a collision occurs, the speed of other vehicles or objects colliding with the vehicle can be detected by a radar device installed on the vehicle body, and the speed of the vehicle can be detected by a speed sensor installed on the vehicle. The radar device sends the speed of other vehicles or objects to the ECU, and the speed sensor sends the speed of the vehicle to the ECU. The ECU calculates the collision speed by calculating the speed difference between the speed of other vehicles or objects and the speed of the vehicle.

[0061] It is understood that, in order to detect whether a collision event has occurred, this application embodiment can detect whether a collision event has occurred by installing a collision detection sensor on the vehicle body. For example, the collision detection sensor can be installed at the front, rear, or side of the vehicle body to detect collision events that occur at the front, rear, or side of the vehicle. Similarly, when the collision detection sensor detects a collision event, it sends a notification to the ECU so that the ECU is aware that a collision event has occurred.

[0062] It is understandable that, in order to more accurately detect whether a collision event has occurred, embodiments of this application can acquire images of the collision event by installing cameras on the vehicle body, for example, by distributing cameras around the vehicle body and on the top of the vehicle body to acquire images, so as to further assist the ECU in making the corresponding collision safety control strategy correctly.

[0063] It is understood that the radar device, speed sensor, collision detection sensor, and camera, etc., in the embodiments of this application can be connected to the ECU controller via wired connection or wireless connection, and no limitation is made here.

[0064] In step S101, the hydrogen supply system refers to a system that supplies hydrogen to the fuel cell system, including a hydrogen storage tank and a hydrogen supply pipeline. The hydrogen storage tank can be installed in a location such as the trunk of the vehicle, and the hydrogen storage tank is connected to the fuel cell system through the hydrogen supply pipeline. In the event of a collision, the hydrogen storage tank and the hydrogen supply pipeline may be deformed or damaged due to the impact, leading to hydrogen leakage and potentially causing an explosion. Therefore, this embodiment of the application needs to detect changes in various attribute information of the hydrogen supply system during a collision event, and further determine whether the hydrogen storage tank or the hydrogen supply pipeline has been damaged or leaking based on these changes.

[0065] In some embodiments, the hydrogen supply system includes at least a hydrogen storage tank, and the attribute information includes at least the location information, deformation information, gas pressure information, and gas flow information of the hydrogen storage tank.

[0066] The position information of the hydrogen storage tank can be detected by a displacement sensor located on one side of the hydrogen storage tank. When the position information of the hydrogen storage tank changes, such as moving from the installation point A to the offset point B, it is considered that the hydrogen storage tank may have shifted or fallen off due to a collision event, resulting in a change in its position information.

[0067] The deformation information of the hydrogen storage tank can be obtained by setting multiple position sensors around the hydrogen storage tank. If the position information of several of the position sensors changes, it is considered that a collision event may have caused compression deformation in some areas of the storage tank. Alternatively, the deformation information of the hydrogen storage tank can also be obtained by setting multiple strain gauges around the hydrogen storage tank and detecting compression deformation in some areas of the storage tank by observing the changes in the electrical signals of the strain gauges.

[0068] The gas pressure information of the hydrogen storage tank can be detected by a pressure sensor installed at the outlet of the hydrogen storage tank. If the pressure sensor at the outlet of the hydrogen storage tank detects a decrease in pressure, it is considered that the gas storage tank may have been damaged due to a collision event, resulting in gas leakage and a decrease in gas pressure.

[0069] The gas flow information of the hydrogen storage tank can be detected by a flow sensor installed at the outlet of the hydrogen storage tank. If the flow sensor at the outlet of the hydrogen storage tank detects a decrease in flow, it is assumed that the gas storage tank may have been damaged due to a collision event, resulting in gas leakage and a decrease in flow.

[0070] It is understood that, in some other embodiments, the hydrogen supply system may further include a hydrogen supply pipeline, and the attribute information includes at least the gas pressure information and airflow information of the hydrogen supply pipeline. Similarly, the gas pressure information and airflow information of the hydrogen supply pipeline can also be detected by a gas pressure sensor and an airflow sensor, respectively, with principles similar to those described above, and will not be repeated here.

[0071] In step S102, the preset mapping relationship refers to establishing a correspondence between different vehicle collision speeds and different expected damage levels of the hydrogen supply system through prior calibration or simulation. For example, calibration may reveal that when the vehicle collision speed is less than V1, the hydrogen supply system does not deform; when the vehicle collision speed is greater than V1 but less than V2, the hydrogen supply system suffers collision damage and slight deformation; and when the vehicle collision speed is greater than V2, the hydrogen supply system suffers collision damage and severe deformation, at which point the risk of gas leakage is very high.

[0072] In step S102, the expected damage level of the hydrogen supply system refers to the level of damage that the hydrogen supply system would typically experience at the corresponding vehicle collision speed.

[0073] Understandably, after establishing a preset mapping relationship, the expected damage level of the hydrogen supply system can be determined based on the vehicle's collision speed. Of course, this expected damage level refers to the degree of damage that the hydrogen supply system might normally experience. However, to prevent this expected damage level from being inapplicable in certain situations, this embodiment further incorporates changes in the hydrogen supply system's attribute information during actual vehicle operation to further assess the damage level, ensuring the accuracy of the results.

[0074] In some embodiments of step S102, the expected damage level of the hydrogen supply system is determined based on a preset mapping relationship according to the vehicle's collision speed, including:

[0075] If the collision speed of the vehicle is less than a first speed threshold, the hydrogen supply system has a first expected degree of damage.

[0076] If the collision speed of the vehicle is between a first speed threshold and a second speed threshold, then the hydrogen supply system has a second expected degree of damage.

[0077] If the collision speed of the vehicle exceeds the second speed threshold, the hydrogen supply system has a third expected degree of damage.

[0078] Wherein, the first speed threshold is less than the second speed threshold, and the damage degree of the first expected damage degree, the second expected damage degree and the third expected damage degree increases sequentially.

[0079] The first speed threshold refers to the minimum speed at which the hydrogen supply system deforms after being subjected to collision and compression. That is, when the collision speed is greater than the first speed threshold, the hydrogen supply system will usually deform to a certain extent, while when the collision speed is less than the first speed threshold, the hydrogen supply system will usually not deform.

[0080] The second speed threshold refers to the minimum speed at which the hydrogen supply system will undergo severe deformation after being subjected to collision and compression. That is, when the collision speed is greater than the second speed threshold, the hydrogen supply system will usually undergo severe deformation, while when the collision speed is less than the second speed threshold but greater than the first speed threshold, the hydrogen supply system will usually undergo a certain degree of deformation.

[0081] Based on the above, the first expected level of damage corresponds to the hydrogen supply system not deforming, at which point the hydrogen supply system usually does not leak gas; the second expected level of damage corresponds to the hydrogen supply system deforming to a certain extent, at which point the hydrogen supply system usually has a certain risk of gas leakage; and the third expected level of damage corresponds to the hydrogen supply system being severely deformed, at which point the hydrogen supply system usually has a great risk of leakage.

[0082] In some embodiments of step S103, based on the expected damage level of the hydrogen supply system and the changes in each of the attribute information, a corresponding collision safety control strategy is executed, including:

[0083] When the hydrogen supply system has a first expected degree of damage:

[0084] If all the attribute information of the hydrogen supply system is normal, then the early warning strategy is executed;

[0085] If at least one of the attribute information of the hydrogen supply system is abnormal, the early warning strategy and the gas supply stop strategy are executed.

[0086] As described above, when the collision speed of the vehicle is less than the first speed threshold, denoted as V1, the first expected damage level of the hydrogen supply system is that it will not deform. To further detect whether the hydrogen supply system is leaking, this embodiment detects the location, deformation, pressure, and airflow information of the hydrogen supply system to identify whether each attribute is abnormal. If all attributes are normal, it indicates that the hydrogen supply system has not deformed, the impact of the collision is minimal, and there is no risk of gas leakage. However, since a collision has occurred, a warning signal still needs to be issued to remind the user to slow down and stop to check the vehicle's collision condition. If any attribute is abnormal, it indicates that although the hydrogen supply system would not normally deform at the current collision speed, unexpected factors (such as ambient temperature) may have occurred during the collision, causing the hydrogen supply system's attribute information to become abnormal. In this case, when issuing a warning signal, the hydrogen supply system should be stopped to prevent gas leakage and potential accidents.

[0087] In some embodiments of step S103, based on the expected damage level of the hydrogen supply system and the changes in each of the attribute information, a corresponding collision safety control strategy is executed, including:

[0088] When the hydrogen supply system has a second anticipated level of damage:

[0089] If all the attribute information of the hydrogen supply system is normal, then the early warning strategy and the gas supply stop strategy are executed;

[0090] If at least one of the attribute information of the hydrogen supply system is abnormal, the early warning strategy, the gas supply stop strategy, and the high-pressure power limiting output strategy are executed.

[0091] As can be seen from the above, when the collision speed of the vehicle is greater than the first speed threshold but less than the second speed threshold, that is, greater than V1 but less than V2, the second expected degree of damage to the hydrogen supply system is that a certain degree of deformation occurs, and the hydrogen supply system has a certain risk of leakage. To further detect whether a leak has occurred in the hydrogen supply system, this embodiment of the application detects the location, deformation, pressure, and airflow information of the hydrogen supply system to identify whether each attribute is abnormal. If all attributes are normal, it means that although the hydrogen supply system has undergone some deformation, it has not yet been damaged or leaked. However, due to the collision, a warning signal and gas supply stoppage are still required to remind the user to slow down and stop to check the collision and damage to the hydrogen supply system. If any attribute is abnormal, it means that at the current collision speed, although the hydrogen supply system would normally deform to some extent but not be damaged or leaked, unexpected factors (such as ambient temperature) may have occurred during the collision, causing the attribute information of the hydrogen supply system to become abnormal. In this case, when issuing a warning signal, the hydrogen supply system should also be controlled to stop gas supply and implement a high-pressure power limiting strategy, so that the vehicle can automatically slow down and stop while cutting off the energy supply to prevent further gas leakage and accidents.

[0092] Understandably, if the user confirms after inspection that the vehicle's condition poses a low risk, the gas supply and high-voltage power output can be restored manually by pressing a button, reducing the likelihood of user complaints due to false alarms.

[0093] In some embodiments of step S103, based on the expected damage level of the hydrogen supply system and the changes in each of the attribute information, a corresponding collision safety control strategy is executed, including:

[0094] When the hydrogen supply system has a third anticipated level of damage:

[0095] If all the attribute information of the hydrogen supply system is normal, then the early warning strategy, the gas supply stop strategy, the high-pressure power limiting output strategy, and the high-pressure power cut-off strategy are executed.

[0096] If at least one of the attribute information of the hydrogen supply system is abnormal, the early warning strategy, the gas supply stop strategy, the high-pressure power limiting output strategy, the high-pressure power cut-off strategy, and the hydrogen storage tank installation point failure strategy are executed.

[0097] In some embodiments, when the hydrogen supply system has a third expected level of damage, if at least one of the attribute information of the hydrogen supply system is abnormal, the method further includes:

[0098] Execute the vehicle restraint system activation strategy.

[0099] As described above, when the vehicle's collision speed exceeds the second speed threshold, i.e., greater than V2, the third expected damage level of the hydrogen supply system is severe deformation, indicating a significant risk of leakage. To further detect whether a leak has occurred in the hydrogen supply system, this embodiment detects the system's location, deformation, pressure, and airflow information, identifying any abnormalities. If all attributes are normal, it indicates that the hydrogen supply system has undergone severe deformation but has not yet experienced damage or gas leakage. However, due to the collision and severe deformation of the hydrogen supply system, a warning signal is issued, gas supply is stopped, the high-voltage electrical system's power output is limited, and the high-voltage system is de-energized. This causes the vehicle to cut off its energy supply and automatically decelerate and stop. The system then decelerates to a certain threshold, for example, 5K. After the speed reaches M / H, the high-voltage system is powered off to bring the vehicle to a rapid stop, alerting the user to check for collision damage and hydrogen supply system damage. If any attribute information is abnormal, it indicates that the hydrogen supply system has been damaged and leaking gas at the current collision speed. In this case, when issuing a warning signal, the system should also stop the gas supply, limit the power output of the high-voltage electrical system, power off the high-voltage system, and disable the hydrogen storage tank mounting point. This would prevent the hydrogen storage tank from detaching from the mounting point and further impact damage, thus guiding the user to slow down and stop while quickly cutting off the energy supply and preventing further damage to the hydrogen storage tank, reducing the risk of an accident.

[0100] It is understood that when the hydrogen supply system has a third expected degree of damage, that is, when the collision speed is greater than the second speed threshold, if at least one of the attribute information of the hydrogen supply system is abnormal, the embodiments of this application also execute the vehicle restraint system activation strategy, that is, activate restraint components such as airbags and seat belts to further protect the occupants.
