Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of vehicle control, in particular to a vehicle collision redundancy unlocking system, method and device. BACKGROUND

[0002] With the improvement of automobile electronicization and automatic driving penetration rate, the vehicle unlocking system has been upgraded from mechanical to electronic control. The electronic control core relies on the main power supply, electronic control unit (ECU) and single sensor to realize the unlocking function, which is widely used in traditional fuel vehicles and new energy vehicles.

[0003] The typical working logic of the existing vehicle unlocking system is as follows: for normal scenarios, the user controls the vehicle door motor to unlock through the key, touch screen or voice command after verification by the electronic control unit (ECU); for emergency scenarios, the impact signal is detected by the collision sensor, and the electronic control unit (ECU) triggers the main power supply to supply power and controls the vehicle to unlock.

[0004] Since the electronic unlocking and mechanical unlocking of the existing vehicle unlocking system rely on the single link of the main power supply, electronic control unit (ECU) and communication line, once this link is damaged due to collision, it will cause a chain failure.

[0005] When the main power supply is powered off or the electronic control unit (ECU) is damaged by collision, the electronic unlocking fails to output the unlocking instruction; the mechanical unlocking needs to rely on the complete structure of the vehicle body, and when the vehicle door is deformed and the cable is broken due to severe collision, the mechanical unlocking fails, and the mechanical unlocking cannot be operated at all, which finally causes the passengers to be trapped, and increases the risk of injury and death of the trapped passengers due to delayed rescue.

[0006] Moreover, the standby power supply used in the existing vehicle unlocking system has weak endurance and limited capacity, and is commonly used with the main power supply or installed in the same area, and is not independent of the main circuit. When a collision occurs, the standby power supply is easily affected by the short circuit and high temperature of the main circuit, resulting in early failure of the standby power supply and inability to support emergency scenarios.

[0007] In addition, the electronic control unit (ECU), standby power supply and sensor are arranged in the high-frequency collision damage areas such as the front of the vehicle and the door, and the installation position is unreasonable. When the area is damaged in a frontal collision, the core components of the vehicle unlocking system are directly damaged; and the existing standby unlocking system has no special impact resistance, waterproof packaging and low protection level. The impact of fragments and electrolyte leakage caused by collision can damage the circuit board, further increasing the risk of unlocking failure.

[0008] The existing vehicle unlocking system needs to pass through multiple links such as sensors, electronic control units (ECUs), main power supplies and motors from detecting a collision by a sensor to executing unlocking, and the response time delay may cause the unlocking action to be stuck by the body deformation before being completed. The unlocking trigger only depends on a single collision sensor, and is easy to cause false unlocking due to bumps or miss detection due to the shielding of the sensor, resulting in false unlocking in a non-emergency situation or no unlocking in an emergency situation. SUMMARY

[0009] In order to solve the problems in the prior art that the existing vehicle unlocking system has single-point failure leading to complete loss of unlocking function, the backup power supply has insufficient endurance and is not independently designed, cannot support emergency scenes, the installation position of the key components is not reasonable and is easy to be damaged, the impact resistance is insufficient, the trigger mechanism has response delay and high risk of false judgment, and cannot accurately respond to emergencies, an embodiment of the present application provides a vehicle collision redundant unlocking system, method and equipment.

[0028] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0029] This embodiment addresses the problems of existing vehicle unlocking systems, such as single-point failure leading to complete loss of unlocking function, insufficient backup power supply and lack of independent design, inability to support emergency scenarios, unreasonable installation location of key components making them easily damaged, insufficient impact resistance, delayed response of triggering mechanism, high risk of misjudgment, and inability to accurately respond to emergencies. It provides a vehicle collision redundancy unlocking system.

[0030] This invention provides a vehicle collision redundancy unlocking system, such as... Figure 1 As shown, it includes: a sensor network 100, a backup unlocking system 200, a main unlocking system 300, and an actuator 400; Sensor network 100 is used to collect accident data of the vehicle and determine whether the vehicle needs to trigger the unlocking function based on the accident data. If so, it determines the unlocking strategy according to the accident level and sends the corresponding unlocking command to the backup unlocking system 200 according to the solution strategy.

[0031] In the embodiment, after the vehicle starts, the sensor network 100 starts to work, real-time acquires sensor data, analyzes the sensor data through a machine learning algorithm, extracts accident data, judges whether the vehicle needs to trigger the unlocking function according to the accident data, if yes, determines the unlocking strategy in combination with the collision intensity and the body deformation and the like, and sends the corresponding unlocking instruction to the standby unlocking system 200 according to the unlocking strategy, so as to balance the safe unlocking and the situation of preventing the accidental door opening according to the accident level.

[0032] The standby unlocking system 200 is used to receive the unlocking instruction sent by the sensor network 100, inquire the working state of the main unlocking system 300 after receiving the unlocking instruction, activate the standby power supply according to the abnormal working state replied by the main unlocking system 300, send the unlocking instruction to the execution mechanism 400 after the standby power supply is activated, and receive the unlocking state feedback signal sent by the execution mechanism 400.

[0033] In the embodiment, when the main unlocking system 300 has no feedback, it can also be considered that the main unlocking system 300 is in an abnormal working state, at this time, the standby power supply is also activated.

[0034] The execution mechanism 400 is used to execute the unlocking operation according to the unlocking instruction sent by the standby unlocking system 200, and send the unlocking state feedback signal to the standby unlocking system 200.

[0035] The main unlocking system 300 is used to query the working state after receiving the working state inquiry instruction sent by the standby unlocking system 200, if the working state is normal, execute the normal unlocking function, if the working state is abnormal, do not respond or send the abnormal working state to the standby unlocking system 200.

[0036] In the embodiment, the standby unlocking system 200 inquires the working state of the main unlocking system 300 after receiving the unlocking instruction, if the working state of the main unlocking system 300 is normal, the main unlocking system 300 executes the normal unlocking process, that is, in the conventional scene, the main unlocking system 300 executes the normal unlocking process, and the standby unlocking system 200 only monitors the state of the main unlocking system 300 and does not participate in the unlocking execution, so as to avoid the resource occupation caused by the simultaneous work of the double unlocking systems; when the main unlocking system 300 is abnormal, the standby unlocking system 200 takes over immediately without switching delay, and the reliability of the conventional and emergency scenes is considered.

[0037] The vehicle collision redundancy unlocking system provided by the embodiment is realized through the cooperation of the backup unlocking system 200 and the main unlocking system 300. When the main unlocking system 300 works normally, the unlocking function is realized according to the normal unlocking process. When the main unlocking system 300 is powered off, the ECU is damaged or the like, the backup unlocking system 200 takes over immediately to form a double guarantee, so as to solve the problem that the unlocking function is completely lost due to single-point failure, avoid the situation that the whole vehicle is locked after the main unlocking system 300 fails, and reduce the risk of injury and death. At the same time, the sensor network 100 comprehensively analyzes the accident data to accurately determine whether to trigger unlocking, formulates an unlocking strategy according to the accident level in combination with multi-dimensional information such as collision intensity and body deformation, intelligently judges the unlocking demand, and avoids false triggering and missed triggering.

[0038] The vehicle collision redundancy unlocking system provided by the embodiment is realized through the cooperation of the backup unlocking system 200 and the main unlocking system 300. When the main unlocking system 300 works normally, the unlocking function is realized according to the normal unlocking process. When the main unlocking system 300 is powered off, the ECU is damaged or the like, the backup unlocking system 200 takes over immediately to form a double guarantee, so as to solve the problem that the unlocking function is completely lost due to single-point failure, avoid the situation that the whole vehicle is locked after the main unlocking system 300 fails, and reduce the risk of injury and death. At the same time, the sensor network 100 comprehensively analyzes the accident data to accurately determine whether to trigger unlocking, formulates an unlocking strategy according to the accident level in combination with multi-dimensional information such as collision intensity and body deformation, intelligently judges the unlocking demand, and avoids false triggering and missed triggering.

[0039] In the embodiment, the emergency mechanism 500 is used for sending a manual trigger signal to the backup unlocking system 200 under manual triggering. After receiving the manual trigger signal, the backup unlocking system 200 sends an unlocking instruction to the execution mechanism 400, so that the execution mechanism 400 performs an unlocking operation according to the unlocking instruction.

[0040] Preferably, the emergency mechanism 500 is a hidden button that can be manually triggered, and is simple to operate. In an emergency, the in-vehicle personnel can manually trigger the hidden button to directly activate the backup power supply of the backup unlocking system 200. After receiving the manual trigger signal, the backup unlocking system 200 does not need to inquire the main unlocking system 300, and directly sends an unlocking instruction to the execution mechanism 400, so that the execution mechanism 400 performs an unlocking operation according to the unlocking instruction to open the vehicle door.

[0041] In the embodiment, the in-vehicle personnel can directly activate the backup unlocking system 200 through the hidden button. Even if the sensor network 100 and the main unlocking system 300 both fail, the unlocking can still be triggered 100%, and the risk of having no unlocking way is completely eliminated.

[0042] The embodiment is a preferred embodiment, and the structure design of the main unlocking system 300 and the backup unlocking system 200 is optimized.

[0043] In the embodiment, the main unlocking system 300 includes a main power supply and a main MCU, and the main MCU is in communication connection with the vehicle ECU.

[0044] The backup unlocking system 200 includes a backup power supply, a backup circuit board and a backup MCU. The backup power supply is packaged in an aluminum alloy box and is installed below the driver's seat. The backup circuit board is isolated from the main unlocking system 300 through an optical coupling, and the backup MCU is isolated from the main MCU through an optical coupling.

[0045] In the embodiment, the backup power supply is packaged in an aluminum alloy box, which improves the impact resistance level, and the backup power supply is installed under the driver's seat to reduce the collision deformation and damage rate; the backup circuit board, the backup MCU and the main unlocking system 300 are optically coupled to isolate the main circuit of the main unlocking system 300 from the backup unlocking system 200, thereby improving the independent working reliability of the backup unlocking system 200.

[0046] In addition, the optical coupling isolation cuts off the electrical connection between the high-voltage circuit and the backup unlocking system 200, thereby avoiding the damage of the backup circuit board caused by the leakage; the backup power supply is independently powered without relying on the high-voltage battery pack, and even if the battery pack is damaged, the unlocking operation can still be supported, so as to completely eliminate the situation of whole vehicle locking caused by single point failure and reduce the risk of injury and death.

[0047] The main MCU receives the unlocking instruction of the whole vehicle ECU to meet the conventional intelligent scene demand; the backup MCU independently operates without relying on the whole vehicle ECU, thereby ensuring that the unlocking can still be autonomously executed when the whole vehicle ECU fails, and the intelligent and redundant safety are taken into account.

[0048] In addition, in the embodiment, when the voltage of the main power supply is less than a preset threshold, the backup power supply is started without intervention.

[0049] Preferably, the preset threshold is set to 9V, when the voltage of the main power supply drops to 9V, the backup power supply is immediately activated, at this time, the main power supply still has a small amount of power, and the instruction transmission of the main power supply to the backup power supply can be completed without switching interruption risk; the backup power supply can support 48 hours of continuous power supply or 100 unlocking operations, and the endurance capability is greatly improved.

[0050] The embodiment is a preferred embodiment, and the structure of the sensor network 100 is optimized.

[0051] In the embodiment, the sensor network 100 at least includes a collision sensor, an air pressure sensor and a smoke sensor.

[0052] The collision sensor is used to collect the collision intensity to detect the impact acceleration, the air pressure sensor is used to collect the air pressure of the vehicle body to detect the deformation of the vehicle body, and the smoke sensor is used to collect the smoke to detect the fire risk, the three are combined to accurately divide the accident level, and the unlocking strategy is determined according to the accident level, and then the corresponding unlocking instruction is sent to the backup unlocking system 200 according to the solution strategy.

[0053] For example, the collision intensity is low but the air pressure drops obviously, which can be considered as the deformation of the vehicle door, and it is still determined to be unlocked; the collision intensity is high but there is no smoke, and the vehicle door is preferentially unlocked rather than the high-voltage circuit is cut off.

[0054] If the smoke concentration is greater than a preset threshold, the collision data does not need to be waited, and the instructions of unlocking the whole vehicle and cutting off the high-voltage circuit are directly triggered.

[0055] In addition, the three types of sensors work independently, so that even if one type of sensor fails, the remaining two types can still assist in judgment, reduce the dependence on a single sensor, and improve the reliability of the sensor network 100.

[0056] In this embodiment as a preferred embodiment, the specific structure of the actuator 400 is optimized.

[0057] In this embodiment, the actuator 400 includes a motor and an electromagnetic lock in communication with the motor, and the motor is in communication with the main unlocking system 300 and the backup unlocking system 200 to receive unlocking instructions sent by the main unlocking system 300 and the backup unlocking system 200 and control the electromagnetic lock to perform corresponding unlocking operations according to the unlocking instructions.

[0058] In this embodiment, the motor receives the unlocking instructions of any one of the main unlocking system 300 or the backup unlocking system 200 to control the electromagnetic lock to unlock.

[0059] When the main unlocking system 300 communication fails, the backup unlocking system 200 can still send unlocking instructions to the actuator 400 through the backup wire harness, thereby improving the signal reception success rate of the actuator 400.

[0060] In some optional embodiments, as shown in Figure 2 The embodiment of the present application also discloses a vehicle collision redundancy unlocking method, which is based on the vehicle collision redundancy unlocking system of any one of the above-mentioned embodiments to perform the unlocking function.

[0061] The vehicle collision redundancy unlocking method disclosed by the embodiment comprises the following steps: S10. The backup unlocking system receives the unlocking instructions sent by the sensor network.

[0062] This step, as shown in Figure 3 specifically comprises: S101. Obtain the sensor data collected by the sensor network.

[0063] S102. Analyze and process the sensor data collected by the sensor network through a machine learning algorithm to determine whether the unlocking function needs to be triggered.

[0064] S103. If the unlocking function needs to be triggered, determine the unlocking strategy according to the accident level.

[0065] S104. Send the corresponding unlocking instructions to the backup unlocking system according to the solution strategy.

[0066] Among them, the sensor network at least includes a collision sensor, an air pressure sensor and a smoke sensor.

[0067] S20. The standby unlocking system inquires the working state of the main unlocking system.

[0068] S30. The standby unlocking system receives the abnormal working state of the main unlocking system or does not receive the reply of the main unlocking system, and activates the standby power supply.

[0070] S50. The standby unlocking system receives the unlocking state feedback signal sent by the actuator after the actuator completes the unlocking operation.

[0071] In the embodiment, the standby unlocking system receives the unlocking instruction sent by the sensor network, and the logic of inquiring the main unlocking system first and then activating the standby unlocking system is clear, so as to avoid the conflict between the two systems; the state feedback, i.e., the actuator sends the state feedback signal of unlocking success to the standby unlocking system after unlocking, is set to facilitate troubleshooting and improve the maintenance efficiency.

[0072] In addition, the inquiry feedback time can be set, and if the main unlocking system does not reply within the preset feedback time, it is considered that the main unlocking system is abnormal, and the standby power supply is activated.

[0073] In the embodiment, the process of unlocking in the vehicle accident is skipped, the main unlocking system fault diagnosis link is skipped, the unlocking is preferentially performed in the emergency scene, and the fault diagnosis is performed in the background after unlocking, so as to not affect the emergency operation.

[0074] The embodiment as the preferred embodiment further includes: The standby unlocking system receives the manual trigger signal.

[0075] The standby unlocking system sends an unlocking instruction to the actuator to make the actuator execute an unlocking operation according to the unlocking instruction.

[0076] That is, in the embodiment, the standby unlocking system receives the manual trigger signal, and directly sends an unlocking instruction to the actuator without inquiring the main system.

[0077] The manual trigger signal directly reaches the standby unlocking system, skips the inquiry link of the main unlocking system, shortens the time from triggering to executing unlocking, and sets the manual trigger signal as the highest priority to ensure that the manual trigger instruction is not delayed.
