[0004] The vehicle is often in a locked state during driving. When a collision occurs during driving, the vehicle door needs to be unlocked immediately to facilitate the escape of the people inside the vehicle and the rescue of the people outside the vehicle. Due to the collision of the vehicle, the whole vehicle wire harness may be affected, and the vehicle controller communication may be in an abnormal state, which may result in the failure of the collision unlocking and the failure of the emergency rescue call, affecting the escape of the vehicle occupants and the rescue of the people outside the vehicle.

[0060] In some embodiments, the collision detection unit 101 is connected to any one of the plurality of domain controllers 102 through at least two lines. The collision detection unit 101 is configured to obtain a collision signal and send the collision signal to the domain controller 102 connected thereto through the at least two lines respectively, wherein the communication mode corresponding to each of the at least two lines is different.

[0061] It should be noted that the communication mode corresponding to each of the at least two lines can be different in that the communication protocols of the lines are different, the types of the lines are different, the signal transmission modes of the lines are different, and the lines can be hardwires, Controller Area Network (CAN) buses, Ethernet, etc. The number of domain controllers 102 can be two or more. The domain controller 102 can be a body domain controller, a cabin domain controller, a chassis domain controller, a power domain controller, etc.

[0062] In some embodiments, if the number of the plurality of domain controllers 102 is two, the collision detection unit 101 can be connected to any one of the two domain controllers 102 through at least two lines respectively, and send the obtained collision signal to the domain controller 102 connected to the collision detection unit 101 through each line.

[0063] In some embodiments, if the number of the plurality of domain controllers 102 is three, the collision detection unit 101 can be connected to any one of the three domain controllers 102 through at least two lines respectively, and send the obtained collision signal to the domain controller 102 connected to the collision detection unit 101 through each line.

[0064] It should be noted that the number of domain controllers 102 is only an exemplary description, which is not limited by the application.

[0065] In some embodiments, any one of the plurality of domain controllers 102 is connected with at least one door lock mechanism 103, for driving the door lock mechanism 103 connected therewith to perform door unlocking based on the received collision signal.

[0066] It should be noted that the domain controller 102 and the door lock mechanism 103 can be connected through a hard wire, a network connection, a CAN bus, etc., and the number of door lock mechanisms 103 can be four, six, etc.

The number of domain controllers 102, the number of door lock mechanisms 103, and the connection mode of the domain controller 102 and the door lock mechanism 103 are only exemplary, and the present application is not limited thereto.

[0068] In some embodiments, after receiving the collision signal, the domain controller 102 can drive one or more door lock mechanisms 103 connected therewith to perform door unlocking according to the built-in collision unlocking software, so as to realize the escape of the vehicle occupants.

[0069] It can be understood that, in the embodiments of the present application, since the collision detection unit 101 is connected with any one of the plurality of domain controllers 102 through at least two lines, the collision detection unit 101 can send the collision signal to the domain controller 102 connected therewith through at least two lines with different communication modes after obtaining the collision signal, so as to realize redundant transmission of the collision signal, improve the possibility of the domain controller receiving the collision signal, drive the door lock mechanism to perform door unlocking, and thus ensure the safety of the vehicle. In addition, since the collision detection unit is only connected with any one of the plurality of domain controllers, but not with each controller to establish a redundant line, the cost of wire harness can be reduced.

[0070] In some embodiments of the present application, the plurality of domain controllers 102 each include a collision unlocking module, and the domain controller 102 drives the corresponding door lock mechanism to perform door unlocking through the collision unlocking module thereof after receiving the collision signal.

[0071] In some embodiments, each domain controller 102 can include a collision unlocking module, which can be a basic software module of the domain controller 102. The collision unlocking module can include a collision unlocking logic module and a door lock driving module. The collision unlocking logic module can analyze the received collision signal and generate corresponding door lock driving instructions to the door lock driving module, so that the door lock driving module can directly drive the door lock mechanism connected with the domain controller to execute the vehicle door unlocking.

[0072] According to the above technical means, each domain controller 102 can drive the door lock mechanism connected with the domain controller 102 to achieve vehicle door unlocking based on the collision unlocking module of the domain controller 102 after receiving the collision signal.

[0073] In some embodiments, the domain controller 102 connected with the collision detection unit 101 includes a collision unlocking logic module, and the other domain controllers 102 not connected with the collision detection unit include a door lock calling module. The collision unlocking logic module can generate a collision instruction based on the received collision signal and send the collision unlocking instruction to the door lock calling module of the other domain controller which establishes a communication connection with the domain controller, to realize the calling of the door lock calling module. The door lock calling module can pass the called information to the collision unlocking module in the domain controller where the door lock calling module is located, so as to drive the door lock mechanism connected with the domain controller to achieve vehicle door unlocking through the collision unlocking module.

[0074] In some embodiments of the present application, the plurality of domain controllers 102 includes a first domain controller 1021; the first domain controller 1021 and the collision detection unit 101 are connected through at least two first lines respectively; the collision detection unit 101 sends the collision signal to the first domain controller 1021 through each first line respectively, and the communication modes of each first line are different.

[0075] In some embodiments, each first line between the first domain controller 1021 and the collision detection unit 101 is independent of each other, that is, the collision signal transmitted between the collision detection unit 101 and the first domain controller 1021 through each first line does not affect each other. The types of each first line are different, and the first line can be a hard line, a CAN bus, an Ethernet, etc. The first domain controller 1021 can be any one of a vehicle body domain controller, an in-cabin domain controller, a chassis domain controller, a power domain controller, etc.

[0076] Exemplarily, if the first line between the collision detection unit 101 and the first domain controller 1021 includes two lines, one line can be a hardwire, and the other line can be a CAN bus or an Ethernet; if the first line between the collision detection unit 101 and the first domain controller 1021 includes three lines, for example, the three first lines are line A, line B and line C respectively, line A can be a hardwire, line B can be a CAN bus, and line C can be an Ethernet; or line A can be a hardwire, line B can be an Ethernet, and line C can be a CAN bus; or line A can be a CAN bus, line B can be a hardwire, and line C can be an Ethernet; or line A can be an Ethernet, line B can be a hardwire, and line C can be a CAN bus; or line A can be an Ethernet, line B can be a CAN bus, and line C can be a hardwire; or line A can be a CAN bus, line B can be an Ethernet, and line C can be a hardwire. The number and types of the first lines are only exemplarily described herein, and the present application does not limit the number and types of the first lines.

[0077] According to the above technical means, the collision detection unit 101 can transmit the collision signal to the first domain controller 1021 through the first lines with different communication modes, realize the redundant transmission of the collision signal, improve the possibility of receiving the collision signal by the first domain controller 1021, and thus improve the possibility of successfully unlocking the door by the door lock mechanism connected with the first domain controller 1021.

[0078] In some embodiments of the present application, the plurality of domain controllers 102 further includes a second domain controller 1022; the first domain controller 1021 and the second domain controller 1022 are connected through at least two second lines respectively; the first domain controller 1021 sends the received collision signal to the second domain controller 1022 through each second line respectively; or the first domain controller 1021 sends the collision unlocking instruction to the second domain controller 1022 through each second line respectively; or the first domain controller 1021 sends the collision signal and the collision unlocking instruction to the second domain controller 1022 through each second line respectively, wherein the collision signal and the collision unlocking instruction can be sent through different second lines, and each second line has different communication modes.

[0079] It should be noted that each second line between the first domain controller 1021 and the second domain controller 1021 is independent of each other, and the collision signal or the collision unlocking instruction can be independently transmitted in each second line. The speed of the collision signal transmission is related to the communication mode of the second line. Each second line has different types and different communication protocols. The second line can be a hardwire, a CAN bus, an Ethernet, etc. The types of the second line and the first line can be the same or different.

[0080] In some embodiments, in the case of transmitting the collision signal and the collision unlocking instruction simultaneously through each second line, part of the second lines can transmit the collision signal, and the other part of the second lines can transmit the collision unlocking instruction. For example, if there are three second lines, line A, line B and line C, the collision signal can be transmitted through line A and line B, and the collision unlocking instruction can be transmitted through line C. In addition, the communication mode or communication protocol of line A, line B and line C is different, the communication protocol of line A can be CAN protocol, the communication protocol of line B can be Ethernet first protocol, and the communication protocol of line C can be Ethernet second protocol. The number of second lines, the type of data transmitted by each second line (collision signal or collision unlocking instruction), and the communication protocol of each second line are only exemplary, and are not limited in the present application.

[0081] In some embodiments, the second domain controller 1022 can be any one of a vehicle body domain controller, a cabin domain controller, a chassis domain controller, a power domain controller, etc. The types of the first domain controller 1021 and the second domain controller 1022 can be the same or different, for example, the first domain controller 1021 and the second domain controller 1022 can both be vehicle body domain controllers; or the first domain controller 1021 is a vehicle body domain controller, and the second domain controller 1022 is a cabin domain controller; or the first domain controller 1021 is a vehicle body domain controller 1021, and the second domain controller 1022 is a chassis domain controller, etc. The types of the first domain controller 1021 and the second domain controller 1022 are only exemplary, and are not limited in the present application.

[0082] In some embodiments, the first domain controller 1021 is connected with the collision detection unit 101, and the second domain controller 1022 is not connected with the collision detection unit 101, but is connected with the first domain controller 1021. Through the second line between the second domain controller 1022 and the first domain controller 1021, the second domain controller 1022 can receive the collision signal or the collision unlocking instruction sent by the first domain controller 1021.

[0083] According to the above technical means, the first domain controller 1021 can transmit the collision signal (or the collision unlocking instruction) to the second domain controller 1022 through multiple second lines with different communication modes, realize the redundant transmission of the collision signal (or the collision unlocking instruction), improve the possibility of the second domain controller 1022 receiving the collision signal (or the collision unlocking instruction), and thus improve the possibility of the door lock mechanism connected with the second domain controller 1022 successfully unlocking the door.

[0084] In some embodiments of the present application, as shown in FIG. 2, the first domain controller 1021 comprises a collision unlocking logic module 10211, and the second domain controller 1022 comprises a first door lock calling module 10221 and a first collision unlocking module 10222; the collision unlocking logic module 10211 generates a collision unlocking instruction according to the received collision signal, and sends the collision unlocking instruction to the first door lock calling module 10221 through the second line; the first door lock calling module 10221 calls the first collision unlocking module 10222 to drive the door lock mechanism connected with the second domain controller 1022 to perform the vehicle door unlocking based on the received collision unlocking instruction.

[0085] In some embodiments, the collision unlocking logic module 10211 can be an application software module integrated in the first domain controller 1021, the first door lock calling module 10221 can be an application software module integrated in the second domain controller 1022, and the first collision unlocking module 10222 can be a basic software module integrated in the second domain controller 1022. After the second domain controller 1022 receives the collision signal sent by the collision detection unit, a collision unlocking instruction can be generated, by which the first door lock calling module 10221 in the second domain controller 1022 is called, and the calling information is transmitted to the first collision unlocking module 10222, so as to realize the vehicle door unlocking.

[0086] According to the above technical means, the collision unlocking logic module generates a collision unlocking instruction according to the received collision signal, and sends the collision unlocking instruction to the first door lock calling module through the second line, so that the first door lock calling module of the second domain controller can call the first collision unlocking module according to the collision unlocking instruction, thereby realizing that the door lock mechanism connected with the second domain controller performs the vehicle door unlocking.

[0087] In some embodiments of the present application, as shown in FIG. 2, after receiving the collision signal, the second domain controller 1022 drives the door lock mechanism connected with the second domain controller 1022 to perform the vehicle door unlocking through the first collision unlocking module 10222.

[0088] In some embodiments, the second domain control 1022 can receive the collision signal sent from the first domain controller 1021, and the first collision unlocking module 10222 built-in the second domain controller 1022 can directly drive the door lock mechanism connected with the second domain controller 1022 to perform the vehicle door unlocking according to the collision signal.

[0089] According to the above technical means, the first collision unlocking module of the second domain controller can directly drive the door lock mechanism connected with the second domain controller to perform the vehicle door unlocking according to the obtained collision signal.

[0090] In some embodiments of the present application, the first domain controller 1021 is connected with at least one door lock mechanism, for driving the at least one door lock mechanism to perform vehicle door unlocking based on the received collision signal; the second domain controller 1022 is connected with other door lock mechanisms except the door lock mechanism connected with the first domain controller 1021, for driving the other door lock mechanisms except the door lock mechanism connected with the first domain controller 1021 to perform vehicle door unlocking based on the received collision signal.

[0091] In some embodiments, the first domain controller 1021 can be connected with one or more door lock mechanisms, and the first domain controller 1021 can directly drive the one or more door lock mechanisms connected with itself to perform vehicle door unlocking after receiving the collision signal sent by the collision detection unit 101. The second domain controller 1022 can be connected with other door lock mechanisms different from the door lock mechanisms connected with the first domain controller 1021. For example, if the door lock mechanisms include four door lock mechanisms, the first domain controller 1021 can be connected with two of the four door lock mechanisms, and the second domain controller 1022 can be connected with the other two door lock mechanisms; or the first domain controller 1021 can be connected with one of the four door lock mechanisms, and the second domain controller 1022 can be connected with the other three door lock mechanisms; or the first domain controller 1021 can be connected with three of the four door lock mechanisms, and the second domain controller 1022 can be connected with the other one door lock mechanism.

[0092] Exemplarily, as shown in FIG. 3, a structure schematic diagram two of a vehicle collision unlocking system provided by an embodiment of the present application is provided. In the vehicle collision unlocking system 100, the plurality of door lock mechanisms 103 include a first door lock mechanism 1031, a second door lock mechanism 1032, a third door lock mechanism 1033, and a fourth door lock mechanism 1034. The first domain controller 1021 is connected with the first door lock mechanism 1031 and the second door lock mechanism 1032 respectively; the second domain controller 1022 is connected with the third door lock mechanism 1033 and the fourth door lock mechanism 1034 respectively.

[0093] In some embodiments, the connection line between the first domain controller 1021 and the first door lock mechanism 1031 can be of the same type or different type as the connection line between the first domain controller 1021 and the second door lock mechanism 1032; the connection line between the second domain controller 1022 and the third door lock mechanism 1033 can be of the same type or different type as the connection line between the second domain controller 1022 and the fourth door lock mechanism.

[0094] In some embodiments, the first domain controller 1021 can drive the first door lock mechanism 1031 and the second door lock mechanism 1032 to perform vehicle door unlocking based on the received collision signal; the second domain controller 1022 can drive the third door lock mechanism 1033 and the fourth door lock mechanism 1034 to perform vehicle door unlocking based on the received collision signal.

[0095] Exemplarily, the first door lock mechanism 1031, the second door lock mechanism 1032, the third door lock mechanism 1033 and the fourth door lock mechanism 1034 can correspond to the left front door (main driver), the left rear door, the right front door (assistant driver) and the right rear door of the vehicle respectively, or correspond to the left front door (main driver), the right front door (assistant driver), the left rear door and the right rear door of the vehicle respectively. After the first domain controller 1021 drives the first door lock mechanism 1031 and the second door lock mechanism 1032 connected thereto to be unlocked, the vehicle doors corresponding to the first door lock mechanism 1031 and the second door lock mechanism 1032 will be opened; after the second domain controller 1022 drives the third door lock mechanism 1033 and the fourth door lock mechanism 1034 connected thereto to be unlocked, the vehicle doors corresponding to the third door lock mechanism 1033 and the fourth door lock mechanism 1034 will be opened. Thus, the safe escape of the vehicle occupants is realized.

[0096] In some embodiments, the second domain controller 1022 can be connected with each door lock mechanism respectively, for driving each door lock mechanism to perform vehicle door unlocking based on the received collision signal. In this case, the first domain controller 1021 is not connected with any door lock mechanism, and only transmits the received collision signal to the second domain controller 1022.

[0097] Exemplarily, if the door lock mechanisms include four, the second domain controller 1022 can be connected with the four door lock mechanisms, and after the first domain controller 1021 receives the collision signal sent by the collision detection unit 101, the first domain controller 1021 can send the collision signal to the second domain controller 1022, and after the second domain controller 1022 receives the collision signal, the second domain controller 1022 can directly drive the four door lock mechanisms connected thereto to perform vehicle door unlocking.

[0098] According to the above technical means, after the first domain controller receives the collision signal, the first domain controller can drive the door lock mechanism connected with the first domain controller to perform vehicle door unlocking, and after the second domain controller receives the collision signal, the second domain controller can drive the door lock mechanism connected with the second domain controller to perform vehicle door unlocking, so as to realize the safe escape of the vehicle occupants.

[0099] In some embodiments of the present application, the plurality of domain controllers 102 further comprises a third domain controller 1023; the third domain controller 1023 and the first domain controller 1021 are connected through at least two third lines respectively; the first domain controller 1021 sends the received collision signal to the third domain controller 1023 through each third line respectively; or, the first domain controller 1021 sends the collision unlocking instruction to the third domain controller 1023 through each third line respectively; or, the first domain controller 1021 sends the collision signal and the collision unlocking instruction to the third domain controller 1023 through each third line respectively, wherein the collision signal and the collision unlocking instruction can be sent through different third lines, and the communication modes of each third line are different.

[0100] It should be noted that the types of the third domain controller 1023 and the first domain controller 1021 can be the same or different, and the types of the third domain controller 1023 and the second domain controller 1022 can be the same or different. The third lines can be hardwires, CAN buses, Ethernet, etc., and the types of each third line are different. The third lines between the second domain controller 1022 and the third domain controller 1023 are independent of each other, and the collision signal or the collision unlocking instruction can be transmitted independently in each third line. The line types of the third lines and the first lines and the second lines can be the same or different. In some embodiments, the third lines between the first domain controller 1021 and the third domain controller 1023 can include two, three, etc. If the third lines include two, one of the third lines can be a hardwire, and the other third line can be an Ethernet or a CAN bus; if the third lines include three, one of the third lines is a hardwire, one of the third lines is a CAN bus, and one of the third lines is an Ethernet. The number of third lines and the types of third lines herein are only exemplary and are not limited in the present application.

[0101] In some embodiments, in the case of transmitting the collision signal and the collision unlocking instruction through each third line at the same time, part of the third lines can transmit the collision signal, and the other part of the third lines can transmit the collision unlocking instruction. For example, if the third lines include line D and line E, the collision unlocking instruction can be transmitted through line D, and the collision signal can be transmitted through line E. The communication protocols of line D and line E are different, and the communication protocol of line E can be a CAN protocol, and the communication mode of line E can be an Ethernet protocol. The number of third lines, the types of data transmitted by each third line (collision signal or collision unlocking instruction), and the communication protocols of each third line herein are only exemplary and are not limited in the present application.

[0102] According to the technical means, the first domain controller 1021 can transmit the collision signal (or the collision unlocking instruction) to the third domain controller 1023 through the third lines with different communication modes respectively, so as to realize the redundant transmission of the collision signal (or the collision unlocking instruction), improve the possibility of the third domain controller 1023 receiving the collision signal (or the collision unlocking instruction), and improve the possibility of the door lock mechanism connected with the third domain controller 1023 successfully unlocking the door.

[0103] In some embodiments of the present application, the first domain controller 1022 comprises a collision unlocking logic module 10221, and the third domain controller 1023 comprises a second door lock calling module 10231 and a second collision unlocking module 10232; the collision unlocking logic module 10221 generates a collision unlocking instruction according to the received collision signal, and sends the collision unlocking instruction to the second door lock calling module 10231 through the third lines; the second door lock calling module 10231 calls the second collision unlocking module 10232 to drive the door lock mechanism connected with the third domain controller 1023 to execute the door unlocking based on the received collision unlocking instruction.

[0104] In some embodiments, the second door lock calling module 10231 can be an application software module integrated in the third domain controller 1023, and the second collision unlocking module 10232 can be a basic software module integrated in the third domain controller 1023. After the third domain controller 1023 receives the collision signal sent by the collision detection unit, a collision unlocking instruction can be generated, by which the second door lock calling module 10231 in the third domain controller 1023 is called, and the calling information is transmitted to the second collision unlocking module 10232, so as to realize the door unlocking.

[0105] According to the technical means, the collision unlocking logic module generates a collision unlocking instruction according to the received collision signal, and sends the collision unlocking instruction to the second door lock calling module through the third lines, so that the second door lock calling module of the third domain controller calls the second collision unlocking module according to the collision unlocking instruction, thereby realizing the door lock mechanism connected with the third domain controller to execute the door unlocking.

[0106] In some embodiments of the present application, the third domain controller 1023 drives the door lock mechanism connected with the third domain controller 1023 to execute the door unlocking through the second collision unlocking module 10232 after receiving the collision signal.

[0107] In some embodiments, the third domain control 1023 can receive the collision signal sent from the first domain controller 1021, and drive the door lock mechanism connected with the third domain controller 1023 to execute the door unlocking according to the collision signal through the second collision unlocking module 10232 built in the third domain controller 1023.

[0108] According to the technical means, the second collision unlocking module of the third domain controller can drive the door lock mechanism connected to the third domain controller to execute the door unlocking according to the obtained collision signal.

[0109] In some embodiments of the present application, the third domain controller 1023 and the second domain controller 1022 are connected through a fourth line, and the second domain controller 1022 and the third domain controller 1023 transmit the collision signal through the fourth line.

[0110] In some embodiments, the fourth line is the same as or different from the first line, the second line and the third line. The fourth line can be a hard line, an Ethernet, a CAN bus or other types of lines.

[0111] In some embodiments, in the case that all the third lines between the first domain controller 1021 and the third domain controller 1023 fail, after the second domain controller 1022 receives the collision signal sent by the first domain controller 1021, the second domain controller 1022 can send the collision signal to the third domain controller through the fourth line; in the case that all the second lines between the first domain controller 1021 and the second domain controller 1022 fail, after the third domain controller 1023 receives the collision signal sent by the first domain controller 1021, the third domain controller 1023 can send the collision signal to the second domain controller through the fourth line, so as to realize the mutual transmission of the collision signal between the second domain controller 1022 and the third domain controller 1023.

[0112] According to the technical means, in the case that the second domain controller 1022 receives the collision signal, the second domain controller 1022 can send the collision signal to the third domain controller 1023 through the fourth line, or in the case that the third domain controller 1023 receives the collision signal, the third domain controller 1023 can send the collision signal to the second domain controller 1022 through the fourth line, so as to ensure that the second domain controller 1022 and the third domain controller 1023 can successfully drive the corresponding door lock mechanism to realize the door unlocking.

[0113] In some embodiments of the present application, the first domain controller 1021 and at least two door lock mechanisms in the plurality of door lock mechanisms 103 are connected respectively, or the second domain controller 1022 and at least two door lock mechanisms in the plurality of door lock mechanisms 103 are connected respectively, or the third domain controller 1023 and at least two door lock mechanisms in the plurality of door lock mechanisms 103 are connected respectively.

The number of door lock mechanisms 103 and the connection mode of the door lock mechanism 103 and the first domain controller 1021, the second domain controller 1022 and the third domain controller 1023 are only exemplary, and the present application is not limited thereto.

[0115] According to the above technical means, the first domain controller 1021 or the second domain controller 1022 or the third domain controller 1023 can drive at least two door lock mechanisms connected with itself according to the received collision signal, so as to realize the unlocking of the vehicle door.

[0116] In some embodiments of the present application, as shown in FIG. 4, in the case where the plurality of door lock mechanisms 103 include the first door lock mechanism 1031, the second door lock mechanism 1032, the third door lock mechanism 1033 and the fourth door lock mechanism 1034, the first domain controller 1021 is connected with the first door lock mechanism 1031, and is used to drive the first door lock mechanism 1031 to perform the unlocking of the vehicle door based on the received collision signal; the second domain controller 1022 is connected with the second door lock mechanism 1032, and is used to drive the second door lock mechanism 1032 to perform the unlocking of the vehicle door based on the received collision signal; the third domain controller 1023 is connected with the third door lock mechanism 1033 and the fourth door lock mechanism 1034 respectively, and is used to drive the third door lock mechanism 1033 and the fourth door lock mechanism 1034 to perform the unlocking of the vehicle door based on the received collision signal.

[0117] In some embodiments, the first domain controller 1021 can be connected with the first door lock mechanism 1031 and the second door lock mechanism 1032 respectively, for driving the first door lock mechanism 1031 and the second door lock mechanism 1032 to perform the vehicle door unlocking based on the received collision signal; the second domain controller 1022 can be connected with the third door lock mechanism 1033, for driving the third door lock mechanism 1033 to perform the vehicle door unlocking based on the received collision signal; and the third domain controller 1023 can be connected with the fourth door lock mechanism 1034, for driving the fourth door lock mechanism 1034 to perform the vehicle door unlocking based on the received collision signal.

[0118] In some embodiments, the first domain controller 1021 can be connected with the first door lock mechanism 1031, for driving the first door lock mechanism 1031 to perform the vehicle door unlocking based on the received collision signal; the second domain controller 1022 and the second door lock mechanism 1032 and the third door lock mechanism 1033 are connected respectively, for driving the second door lock mechanism 1032 and the third door lock mechanism 1033 to perform the vehicle door unlocking based on the received collision signal; and the third domain controller 1023 is connected with the fourth door lock mechanism 1034, for driving the fourth door lock mechanism 1034 to perform the vehicle door unlocking based on the received collision signal.

[0119] In some embodiments, the first domain controller 1021 can be connected with the first door lock mechanism 1031 and the second door lock mechanism 1032, for driving the first door lock mechanism 1031 and the second door lock mechanism 1032 to perform the vehicle door unlocking based on the received collision signal; the second domain controller 1022 and the third door lock mechanism 1033 and the fourth door lock mechanism 1034 are connected respectively, for driving the third door lock mechanism 1033 and the fourth door lock mechanism 1034 to perform the vehicle door unlocking based on the received collision signal.

[0120] It can be understood that, according to the above technical means, the first domain controller 1021 can drive the first door lock mechanism 1031 to perform the vehicle door unlocking after receiving the collision signal, the second domain controller 1022 can drive the second door lock mechanism 1022 to perform the vehicle door unlocking after receiving the collision signal, and the third domain controller 1023 can drive the third door lock mechanism 1033 and the fourth door lock mechanism 1034 to perform the vehicle door unlocking after receiving the collision signal.

[0121] In some embodiments of the present application, the vehicle collision unlocking system 100 can further include an emergency call controller 104 connected with the collision detection unit 101; the emergency call controller 104 is used to output emergency rescue information based on the collision signal after receiving the collision signal sent by the collision detection unit 101.

[0122] In some embodiments, the emergency call controller 104 and the crash detection unit 101 can be connected through a hard-wired connection, or through an Ethernet connection, or through a CAN bus connection, or through other means. The emergency call controller 104 can be an emergency call (E-CALL) controller with Internet access function. When the emergency call controller 104 receives the crash signal sent by the crash detection unit 101, it can output emergency rescue information. The output of the emergency rescue information can be to make an emergency rescue call, or to output the information that needs rescue by voice to seek external help.

[0123] In some embodiments, the emergency call controller 104 and the domain controller 102 can be connected through at least one line. When there are multiple lines between the emergency call controller 104 and the domain controller 102, the communication modes of the lines are different. Through the connection line between the emergency call controller 104 and the domain controller 102, when the connection line between the crash detection unit 101 and the domain controller 102 fails, the crash signal can be sent to the domain controller 102 through the emergency call controller 104, so that the domain controller 102 can still receive the crash signal to drive the corresponding door lock mechanism 103 to unlock the door. Similarly, when the line between the crash detection unit 101 and the emergency call controller fails, the crash signal can also be sent to the emergency call controller 104 through the domain controller 102, improving the possibility of the emergency call controller 104 receiving the crash signal.

[0124] According to the above technical means, the emergency call controller 104 can output emergency rescue information after receiving the crash signal sent by the crash detection unit 101, so as to seek external help in time and improve the safety of the vehicle.

[0125] In some embodiments of the present application, the first domain controller 1021 can be connected to the emergency call controller 104 through at least two fifth lines respectively; the first domain controller 1021 sends the received crash signal to the emergency call controller 1021 through each fifth line respectively, and the communication modes of the fifth lines are different.

[0126] It should be noted that the fifth line can be the same as or different from the first line, the second line, the third line and the fourth line. The types of the fifth lines are different. The fifth line can be a hard-wired line, a CAN bus, an Ethernet, etc. The fifth lines are independent of each other.

[0127] In some embodiments, the first domain controller 1021 can send the collision signal obtained from the collision detection unit 103 to the emergency call controller 1021 through the fifth line; in other embodiments, in the case of a failure of the first line between the collision detection unit 103 and the first domain controller 1021, the emergency call controller 104 can also send the collision signal sent by the collision detection unit 103 to the first domain controller 1021 through the fifth line after receiving the collision signal, so that the first domain controller 1021 can drive the door lock mechanism connected thereto to perform door unlocking after receiving the collision signal.

[0128] In some embodiments, as shown in FIG. 3, the fifth line between the first domain controller 1021 and the emergency call controller 104 can include two, and the two fifth lines can simultaneously transmit the collision signal without affecting each other.

[0129] According to the above technical means, the first domain controller 1021 can send the collision signal to the emergency call controller 104 through each fifth line, so that the emergency call controller 104 can output the emergency rescue information based on the collision signal, and realize timely off-vehicle rescue.

[0130] In some embodiments of the present application, any one of the plurality of domain controllers 102 includes an emergency call unit; the emergency call unit is configured to output the emergency rescue information based on the collision signal after any one of the plurality of domain controllers 102 receives the collision signal.

[0131] In some embodiments, if the plurality of domain controllers 102 includes the first domain controller 1021, the second domain controller 1022 and the third domain controller 1023, any one of the plurality of domain controllers 102 can be the first domain controller 1021, the second domain controller 1022 or the third domain controller 1023.

[0132] In some embodiments, if the first domain controller 1021 integrates the emergency call unit, the emergency call unit in the first domain controller 1021 can output the emergency rescue information after the first domain controller receives the collision signal; if the second domain controller 1022 integrates the emergency call unit, the emergency call unit in the second domain controller 1022 can output the emergency rescue information after the second domain controller 1022 receives the collision signal; if the third domain controller 1023 integrates the emergency call unit, the emergency call unit in the third domain controller 1023 can output the emergency rescue information after the third domain controller 1023 receives the collision signal.

[0133] According to the above technical means, the collision detection unit 101 can send the collision signal to the domain controller 102 connected with the collision detection unit through at least two lines with different communication modes, realize the redundant transmission of the collision signal, improve the possibility of the domain controller 102 receiving the collision signal, and thus drive the corresponding door lock mechanism 103 to execute the vehicle door unlocking, and ensure the safety of the vehicle.

[0134] In some embodiments of the present application, the collision detection unit 101 can be integrated in the domain controller 102, for example, integrated in the first domain controller 1021, so that the first domain controller 1021 can detect the collision signal. After the collision detection unit 101 in the first domain controller 1021 detects the collision signal, the collision detection unit 101 can send the collision signal to the second domain controller 1022 and / or the third domain controller 1023; or generate a collision unlocking instruction according to the detected collision signal, and send the generated collision unlocking instruction to the first door lock calling module 10221 of the second domain controller 1022 and / or the second door lock calling module 10231 of the third domain controller 1023. In addition, the first domain controller 1021 can also send the detected collision signal to the emergency call controller 104 to output the emergency call information through the emergency call controller 104.

[0135] It should be noted that in the whole vehicle distributed domain controller architecture, the plurality of domain controllers 102 provided in the embodiments of the present application can not only include the first domain controller 1021, the second domain controller 1022 and the third domain controller 1023, i.e., can include more than three. In addition, without considering the cost of wire harness, the first line, the second line, the third line and the fifth line mentioned in the foregoing embodiments of the present application can each include more than two, and the collision signal can be transmitted independently between each line.

[0136] Next, the implementation process of the embodiments of the present application in the actual application scenario will be introduced.

[0137] FIG. 5 is a structure schematic diagram of a collision unlocking and emergency rescue call redundancy system provided by an embodiment of the present application. The collision unlocking and emergency rescue call redundancy system 200 includes a collision detection unit 201 (equivalent to the “collision detection unit 101” in other embodiments), two domain controllers 202 (equivalent to the “domain controller 102” in other embodiments), four door lock mechanisms 203 (equivalent to the “door lock mechanism 103” in other embodiments), and an E-Call controller unit 204 (equivalent to the “emergency call controller 104” in other embodiments).

[0138] The collision detection unit 201 is connected with the first domain controller 2021 through the sixth line A and the sixth line B (equivalent to the "at least two first lines" in other embodiments), and the first domain controller 2021 (equivalent to the "first domain controller 1021" in other embodiments). There is a seventh line A and a seventh line B (equivalent to the "at least two second lines" in other embodiments) between the first domain controller 2021 and the second domain controller 2022 (equivalent to the "second domain controller 1022" in other embodiments) for connection. The first domain controller 2021 is connected with the first door lock mechanism 2031 (equivalent to the "first door lock mechanism 1031" in other embodiments) and the third door lock mechanism 2033 (equivalent to the "third door lock mechanism 1033" in other embodiments) through hard lines respectively. The second domain controller 2022 is connected with the second door lock mechanism 2032 (equivalent to the "second door lock mechanism 1032" in other embodiments) and the fourth door lock mechanism 2034 (equivalent to the "fourth door lock mechanism 1034" in other embodiments) through hard lines respectively. The E-Call controller 204 is connected with the collision detection unit 201 through the eighth line, and is connected with the first domain controller 2021 through the ninth line A and the ninth line B (equivalent to the "at least two fifth lines" in other embodiments).

[0139] When the vehicle collides, the collision detection unit 201 sends the collision signal to the first domain controller 2021 through the sixth line A and the sixth line B, and sends the collision signal to the E-Call controller 204 through the eighth line.

[0140] It should be noted that the sixth line A and the sixth line B are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If the sixth line A is damaged during the collision, the collision detection unit 201 can still transmit the collision signal to the first domain controller 2021 through the sixth line B; if the sixth line B is damaged during the collision, the collision detection unit 201 can still transmit the collision signal to the first domain controller 2021 through the sixth line A. In this way, the redundancy of the collision signal transmission is realized, and the system safety is improved.

[0141] After receiving the collision signal, the first domain controller 2021 drives the first door lock mechanism 2031 and the third door lock mechanism 2033 to perform collision unlocking according to the built-in collision unlocking software through the hard line; at the same time, the collision signal received is sent to the second domain controller 2022 through the seventh line A and the seventh line B through software processing; and the collision signal is sent to the E-Call controller 204 through the ninth line A and the ninth line B.

[0142] It should be noted that the seventh line A and the seventh line B are independent of each other, and the collision signal is sent on the two lines and is not affected by each other. If the seventh line A is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the second domain controller 2022 through the seventh line B; if the seventh line B is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the second domain controller 2022 through the seventh line A.

[0143] Similarly, the ninth line A and the ninth line B are independent of each other, and the collision signal is sent on the two lines and is not affected by each other. If the ninth line A is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the E-Call controller 204 through the ninth line B; if the ninth line B is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the E-Call controller 204 through the ninth line A.

[0144] In this way, the redundancy of the collision signal transmission is realized, and the system safety is improved.

[0145] After receiving the collision signal, the second domain controller 2022 will execute the collision unlocking according to the built-in collision unlocking software, and drive the second door lock mechanism 2032 and the fourth door lock mechanism 2034 through the hard line.

[0146] After receiving the collision signal, the E-Call controller 204 will dial an emergency rescue call phone to report the collision time and vehicle location information, etc., to improve the rescue efficiency.

[0147] According to the above system scheme, even if there is a certain degree of wiring harness damage during the collision process, each domain controller can still drive the door lock mechanism to execute the collision unlocking and dial an emergency rescue call phone, thereby improving the system safety.

[0148] FIG. 6 is a structure schematic diagram II of a collision unlocking and emergency rescue call redundancy system provided by an embodiment of the present application. The collision unlocking and emergency rescue call redundancy system 200 comprises a collision detection unit 201, three domain controllers 202, four door lock mechanisms 203, an E-Call controller 204, and the like.

[0149] The collision detection unit 201 is connected with the first domain controller 2021 through the sixth line A and the sixth line B; the seventh line A and the seventh line B are connected between the first domain controller 2021 and the second domain controller 2022; the tenth line A and the tenth line B (equivalent to the at least two third lines in other embodiments) are connected between the first domain controller 2021 and the third domain controller 2023 (equivalent to the third domain controller 1023 in other embodiments); the eleventh line (equivalent to the fourth line in other embodiments) is connected between the second domain controller 2022 and the third domain controller 2023; the first domain controller 2021 is connected with the first door lock mechanism 2031 through a hard line; the second domain controller 2022 is connected with the second door lock mechanism 2032 through a hard line; the third domain controller 2023 is connected with the third door lock mechanism 2033 and the fourth door lock mechanism 2034 through hard lines respectively; the E-Call controller 204 is connected with the collision detection unit 201 through the eighth line, and is connected with the first domain controller 2021 through the ninth line A and the ninth line B.

[0150] When the vehicle collides, the collision detection unit 201 sends the collision signal to the first domain controller 2021 through the sixth line A and the sixth line B, and sends the collision signal to the E-Call controller 204 through the eighth line.

[0151] It should be noted that the sixth line A and the sixth line B are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If the sixth line A is damaged during the collision, the collision detection unit 201 can still transmit the collision signal to the first domain controller 2021 through the sixth line B; if the sixth line B is damaged during the collision, the collision detection unit 201 can still transmit the collision signal to the first domain controller 2021 through the sixth line A. In this way, the redundancy of the collision signal transmission is realized, and the system safety is improved.

[0152] After receiving the collision signal, the first domain controller 2021 drives the first door lock mechanism 2031 to perform collision unlocking through a hard line according to the built-in collision unlocking software; at the same time, the collision signal received is sent to the second domain controller 2022 through the seventh line A and the seventh line B, to the third domain controller 2023 through the tenth line A and the tenth line B, and to the E-Call controller 204 through the ninth line A and the ninth line B through software processing.

[0153] It should be noted that the seventh line A and the seventh line B are independent of each other, and the collision signal is sent on the two lines and is not affected by each other. If the seventh line A is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the second domain controller 2022 through the seventh line B; if the seventh line B is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the second domain controller 2022 through the seventh line A.

[0154] Similarly, the tenth line A and the tenth line B are independent of each other, and the collision signal is sent on the two lines and is not affected by each other. If the tenth line A is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the third domain controller 2023 through the tenth line B; if the tenth line B is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the third domain controller 2023 through the tenth line A.

[0155] Similarly, the ninth line A and the ninth line B are independent of each other, and the collision signal is sent on the two lines and is not affected by each other. If the ninth line A is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the E-Call controller 204 through the ninth line B; if the ninth line B is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the E-Call controller 204 through the ninth line A.

[0156] In addition, there is also an eleventh line between the second domain controller 2022 and the third domain controller 2023, which can also transmit the collision signal.

[0157] After the second domain controller 2022 receives the collision signal, it will execute the collision unlocking according to the built-in collision unlocking software by driving the second door lock mechanism 2032 through the hard line; at the same time, after software processing, the received collision signal is sent to the third domain controller 2023 through the eleventh line.

[0158] After the third domain controller 2023 receives the collision signal, it will execute the collision unlocking according to the built-in collision unlocking software by driving the third door lock mechanism 2033 and the fourth door lock mechanism 2034 through the hard line; at the same time, after software processing, the received collision signal is sent to the second domain controller 2022 through the eleventh line.

[0159] In the redundancy of the eleventh line, if the seventh line A, the seventh line B and the tenth line A are damaged in the collision process, the third domain controller 2023 can also receive the collision signal from the tenth line B and drive the third door lock mechanism 2033 and the fourth door lock mechanism 2034 to be unlocked, and then send the collision signal to the second domain controller 2022 through the eleventh line and ensure that the second door lock mechanism 2032 is unlocked; if the seventh line A, the seventh line B and the tenth line B are damaged in the collision process, the third domain controller 2023 can also receive the collision signal from the tenth line A and drive the third door lock mechanism 2033 and the fourth door lock mechanism 2034 to be unlocked, and then send the collision signal to the second domain controller 2022 through the eleventh line and ensure that the second door lock mechanism 2032 is unlocked; if the seventh line A, the tenth line A and the tenth line B are damaged in the collision process, the second domain controller 2022 can also receive the collision signal from the seventh line B and drive the second door lock mechanism 2032 to be unlocked, and then send the collision signal to the third domain controller 2023 through the eleventh line and ensure that the third door lock mechanism 2033 and the fourth door lock mechanism 2034 are unlocked; if the seventh line B, the tenth line A and the tenth line B are damaged in the collision process, the second domain controller 2022 can also receive the collision signal from the seventh line A and drive the second door lock mechanism 2032 to be unlocked, and then send the collision signal to the third domain controller 2023 through the eleventh line and ensure that the third door lock mechanism 2033 and the fourth door lock mechanism 2034 are unlocked.

[0160] After the E-Call controller 204 receives the collision signal, it will dial an emergency rescue call phone to report the collision time and vehicle location and other information, thereby improving the rescue efficiency.

[0161] FIG. 7 is a structural schematic diagram of a collision unlocking and emergency rescue call redundancy system according to an embodiment of the present application. The collision unlocking and emergency rescue call redundancy system 200 comprises a collision detection unit 201, three domain controllers 202, four door lock mechanisms 203, an E-Call controller 204 and the like.

[0162] The collision detection unit 201 is connected with the first domain controller 2021 through the sixth line A and the sixth line B; the seventh line A and the seventh line B are connected between the first domain controller 2021 and the second domain controller 2022; the tenth line A and the tenth line B are connected between the first domain controller 2021 and the third domain controller 2023; the eleventh line is connected between the second domain controller 2022 and the third domain controller 2023; the first domain controller 2021 is connected with the first door lock mechanism 2031 and the third door lock mechanism 2033 through the hard line; the second domain controller 2022 is connected with the second door lock mechanism 2032 and the fourth door lock mechanism 2034 through the hard line respectively; the E-Call controller 204 is connected with the collision detection unit 201 through the eighth line, and is connected with the first domain controller 2021 through the ninth line A and the ninth line B.

[0163] When the vehicle collides, the collision detection unit 201 sends the collision signal to the first domain controller 2021 through the sixth line A and the sixth line B, and sends the collision signal to the E-Call controller 204 through the eighth line.

[0164] It should be noted that the sixth line A and the sixth line B are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If the sixth line A is damaged during the collision, the collision detection unit 201 can still transmit the collision signal to the first domain controller 2021 through the sixth line B; if the sixth line B is damaged during the collision, the collision detection unit 201 can still transmit the collision signal to the first domain controller 2021 through the sixth line A. In this way, the redundancy of the collision signal transmission is realized, and the system safety is improved.

[0165] After receiving the collision signal, the first domain controller 2021 drives the first door lock mechanism 2031 and the third door lock mechanism 2033 to execute the collision unlocking according to the built-in collision unlocking software through the hard line; at the same time, the collision signal received is sent to the second domain controller 2022 through the seventh line A and the seventh line B, to the third domain controller 2023 through the tenth line A and the tenth line B, and to the E-Call controller 204 through the ninth line A and the ninth line B through software processing.

[0166] It should be noted that the seventh line A and the seventh line B are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If the seventh line A is damaged during the collision, the first domain controller 2021 can still transmit the collision signal to the second domain controller 2022 through the eighth line B; if the eighth line B is damaged during the collision, the first domain controller 2021 can still transmit the collision signal to the second domain controller 2022 through the eighth line A.

[0167] Similarly, the tenth line A and the tenth line B are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If the tenth line A is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the third domain controller 2023 through the tenth line B; if the tenth line B is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the third domain controller 2023 through the tenth line A.

[0168] Similarly, the ninth line A and the ninth line B are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If the ninth line A is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the E-Call controller 204 through the ninth line B; if the ninth line B is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the E-Call controller 204 through the ninth line A.

[0169] In addition, there is also an eleventh line between the second domain controller 2022 and the third domain controller 2023, which can also transmit the collision signal.

[0170] After the second domain controller 2022 receives the collision signal, it will execute the collision unlocking according to the built-in collision unlocking software through the hard-wired second door lock mechanism 2032 and the fourth door lock mechanism 2034; at the same time, after software processing, the received collision signal is sent to the third domain controller 2023 through the eleventh line.

[0171] The third domain controller 2023 processes the received collision signal through software and sends it to the second domain controller 2022 through the eleventh line.

[0172] Under the redundancy guarantee of the eleventh line, if the seventh line A, the seventh line B, and the tenth line A are all damaged during the collision process, the third domain controller 2023 can also receive the collision signal from the tenth line B, and then transmit the collision signal to the second domain controller 2022 through the eleventh line and ensure that the second door lock mechanism 2032 and the fourth door lock mechanism 2034 are unlocked; if the seventh line A, the seventh line B, and the tenth line B are all damaged during the collision process, the third domain controller 2023 can also receive the collision signal from the tenth line A, and then transmit the collision signal to the second domain controller 2022 through the eleventh line and ensure that the second door lock mechanism 2032 and the fourth door lock mechanism 2034 are unlocked.

[0173] After the E-Call controller 204 receives the collision signal, it will dial an emergency rescue call phone to report the collision time and vehicle location information, etc., to improve the rescue efficiency.

[0174] Fig. 8 is a structural diagram of a collision unlocking and emergency call redundancy system according to an embodiment of the present application. The collision unlocking and emergency call redundancy system 200 comprises a collision detection unit 201, three domain controllers 202, four door lock mechanisms 203, an E-Call controller 204, and the like, and the communication forms between the units are also specified.

[0175] The collision detection unit 201 is connected to the first domain controller 2021 through a hardwire and CAN1; the first domain controller 2021 and the second domain controller 2022 are connected through CAN2 and Ethernet 1; the first domain controller 2021 and the third domain controller 2023 are connected through CAN3 and Ethernet 2; the second domain controller 2022 and the third domain controller 2023 are connected through Ethernet 3; the first domain controller 2021 is connected to the first door lock mechanism 2031 through a hardwire; the second domain controller 2022 is connected to the second door lock mechanism 2032 through a hardwire; the third domain controller 2023 is connected to the third door lock mechanism 2033 and the fourth door lock mechanism 2034 through hardwires; the E-Call controller 204 is connected to the collision detection unit 201 through a hardwire, and is connected to the first domain controller 2021 through CAN4 and Ethernet 4.

[0176] When the vehicle is in a collision, the collision detection unit 201 sends a collision signal to the first domain controller 2021 through a hardwire and CAN1, and sends the collision signal to the E-Call controller 204 through a hardwire.

[0177] It should be noted that the hardwire and CAN1 are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If the hardwire is damaged during the collision, the collision detection unit 201 can still transmit the collision signal to the first domain controller 2021 through CAN1; if CAN1 is damaged during the collision, the collision detection unit 201 can still transmit the collision signal to the first domain controller 2021 through the hardwire. In this way, the redundancy of the collision signal transmission is realized, and the system safety is improved.

[0178] After receiving the collision signal, the first domain controller 2021 drives the first door lock mechanism 2031 to perform collision unlocking through a hardwire according to the built-in collision unlocking software; at the same time, the collision signal is sent to the second domain controller 2022 through CAN2 and Ethernet 1, to the third domain controller 2023 through CAN3 and Ethernet 2, and to the E-Call controller 204 through CAN4 and Ethernet 4 after software processing.

[0179] It should be noted that CAN2 and Ethernet1 are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If CAN2 is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the second domain controller 2022 through Ethernet1; if Ethernet1 is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the second domain controller 2022 through CAN2.

[0180] Similarly, CAN3 and Ethernet2 are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If CAN3 is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the third domain controller 2023 through Ethernet2; if Ethernet2 is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the third domain controller 2023 through CAN3.

[0181] Similarly, CAN4 and Ethernet4 are independent of each other, and the collision signal is sent on the two lines respectively and is not affected by each other. If CAN4 is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the E-Call controller 204 through Ethernet4; if Ethernet4 is damaged during the collision process, the first domain controller 2021 can still transmit the collision signal to the E-Call controller 204 through CAN4.

[0182] In addition, there is also Ethernet3 between the second domain controller 2022 and the third domain controller 2023, which can also transmit the collision signal.

[0183] After the second domain controller 2022 receives the collision signal, it will execute the collision unlocking according to the built-in collision unlocking software by driving the second door lock mechanism 2032 through the hard line; at the same time, after software processing, the received collision signal is sent to the third domain controller 2023 through Ethernet3.

[0184] After the third domain controller 2023 receives the collision signal, it will execute the collision unlocking according to the built-in collision unlocking software by driving the third door lock mechanism 2033 and the fourth door lock mechanism 2034 through the hard line; at the same time, after software processing, the received collision signal is sent to the second domain controller 2022 through Ethernet3.

[0185] Under the redundancy guarantee of Ethernet 3, if CAN2, Ethernet 1, CAN3 are all damaged in the collision process, the third domain controller 2023 can also receive the collision signal from Ethernet 2 and drive the third door lock mechanism 2033 and the fourth door lock mechanism 2034 to be unlocked, and then send the collision signal to the second domain controller 2022 through Ethernet 3 and ensure the second door lock mechanism 2032 to be unlocked; if CAN2, Ethernet 1, Ethernet 2 are all damaged in the collision process, the third domain controller 2023 can also receive the collision signal from CAN3 and drive the third door lock mechanism 2033 and the fourth door lock mechanism 2034 to be unlocked, and then send the collision signal to the second domain controller 2022 through Ethernet 3 and ensure the second door lock mechanism 2032 to be unlocked; if CAN2, CAN3, Ethernet 2 are all damaged in the collision process, the second domain controller 2022 can also receive the collision signal from Ethernet 1 and drive the second door lock mechanism 2032 to be unlocked, and then send the collision signal to the third domain controller 2023 through Ethernet 3 and ensure the third door lock mechanism 2033 and the fourth door lock mechanism 2034 to be unlocked; if Ethernet 1, CAN3, Ethernet 2 are all damaged in the collision process, the second domain controller 2022 can also receive the collision signal from CAN2 and drive the second door lock mechanism 2032 to be unlocked, and then send the collision signal to the third domain controller 2023 through Ethernet 3 and ensure the third door lock mechanism 2033 and the fourth door lock mechanism 2034 to be unlocked.

[0186] After the E-Call controller 204 receives the collision signal, it will dial an emergency rescue call to report the collision time and vehicle location, etc., to improve the rescue efficiency.

[0187] FIG. 9 is a schematic diagram of collision signal transmission and calling between domain controllers according to an embodiment of the present application. When a collision occurs, the first domain controller 2021, the second domain controller 2022, and the third domain controller 2023 transmit a collision signal through the CAN protocol and the first Ethernet communication protocol. Then, each domain controller drives unlocking through the software integrated in the underlying software. In addition, after receiving the collision signal, the first domain controller 2021 forwards the collision signal to the second domain controller 2022 and the third domain controller 2023, and directly calls the software of the controller under which the door lock mechanism is hung to perform unlocking through the second Ethernet communication protocol (the collision unlocking logic module in the application software of the first domain controller 2021 sends an instruction to the door lock calling module of the second domain controller 1022 (equivalent to the "first door lock calling module 10221" in other embodiments) and the door lock calling module of the third domain controller 1023 (equivalent to the "second door lock calling module 10231" in other embodiments). After receiving the calling instruction, the door lock calling module of the second domain controller 1022 and the door lock calling module of the third domain controller 1023 can transmit the calling instruction to the collision unlocking logic module in the underlying software, and drive the corresponding door lock mechanism through the door lock driving module to achieve door unlocking). That is, the collision signal is forwarded through the first Ethernet communication protocol, and the interface is called to drive unlocking through the second Ethernet communication protocol. The two Ethernet communication protocols are independent of each other and are redundant. If the first communication protocol stack of the controller fails during the collision process, the second protocol can still ensure unlocking. If the second communication protocol stack of the controller fails during the collision process, the first protocol can still ensure unlocking. The above Ethernet protocol can be Scalable Service-Oriented Middleware over IP (SOME-IP), Data Distribution Service (DDS), etc.

[0188] The collision unlocking and emergency rescue call redundancy system provided by the embodiments of the present application uses multi-line redundancy and multi-protocol redundancy between controllers to improve the possibility of successfully unlocking the vehicle door and making an emergency rescue call when the vehicle collides. Even if part of the wire harness is damaged in the collision or even part of the controller is affected by the collision, the vehicle can still successfully unlock the four door locks and make an emergency rescue call, ensuring that the vehicle occupants can escape and the outside rescue can be performed in time, greatly improving the safety of the vehicle.

[0189] The embodiment of the present application provides a vehicle collision unlocking method, which is applied to the vehicle collision unlocking system 100 provided by the embodiment of the present application, and the vehicle collision unlocking system 100 comprises a collision detection unit 101, a plurality of domain controllers 102 and a plurality of door lock mechanisms 103. As shown in FIG. 10, the vehicle collision unlocking method comprises the following steps:

[0190] S301, the collision detection unit 101 sends a collision signal to the domain controller 102 connected to the collision detection unit through at least two lines after receiving the collision signal.

[0191] It should be noted that the communication modes of the at least two lines are different, each line can be a hard line, an Ethernet or a CAN bus, and the domain controller 102 is any one of the plurality of domain controllers.

[0192] In some embodiments, when the vehicle collides, the collision detection unit 101 can detect a collision signal, which is used to indicate that the vehicle currently collides, and the collision detection unit 101 can send the collision signal to the domain controller 102 connected to the collision detection unit through each line after receiving the collision signal.

[0193] In some embodiments, the line between the collision detection unit 101 and the domain controller 102 connected to the collision detection unit 101 can be two or more, and the collision detection unit 101 can send the collision signal to the corresponding domain controller 102 through each line after detecting the collision signal, and each line does not affect each other. In practice, because the communication modes of different lines are different, the time when the collision signal reaches the domain controller 102 can be different.

[0194] S302, the domain controller 102 drives the door lock mechanism 103 connected to the domain controller 102 to execute the vehicle door unlocking based on the received collision signal.

[0195] In some embodiments, the door lock mechanism 103 connected to the domain controller 102 can comprise one or more. In the case that the door lock mechanism connected to the domain controller 102 comprises a plurality of door lock mechanisms, the domain controller 102 can simultaneously transmit the collision signal to each door lock mechanism 103 after receiving the collision signal.

[0196] In the vehicle collision unlocking method provided in the embodiments of the present application, the collision detection unit 101 sends the collision signal to the domain controller 102 connected to the collision detection unit through at least two lines respectively, so that even if part of the lines between the collision detection unit and the domain controller 102 fails, the successful transmission of the collision signal can be realized, the possibility of the domain controller 102 receiving the collision signal is improved, and further, the domain controller 102 can drive the corresponding door lock mechanism 103 based on the received collision signal, thereby improving the safety of the vehicle.

[0197] In some embodiments, if the vehicle collision unlocking system 100 includes an emergency call controller 104, the collision detection unit 101 can also send the collision signal to the emergency call controller 104 connected thereto after detecting the collision signal, and the emergency call controller 104 outputs emergency rescue information based on the collision signal after receiving the collision signal sent by the collision detection unit 101.

[0199] In some embodiments, if the plurality of domain controllers 102 further includes a second domain controller 1022, the first domain controller 1021 and the second domain controller 1022 are connected through at least two second lines respectively, and the first domain controller 1021 can send the received collision signal to the second domain controller 1022 through each second line respectively after receiving the collision signal, so that the second domain controller 1022 drives the door lock mechanism 103 connected thereto to perform the vehicle door unlocking based on the collision signal.

[0200] In some embodiments, if the plurality of door lock mechanisms 103 include a first door lock mechanism 1031, a second door lock mechanism 1032, a third door lock mechanism 1033, and a fourth door lock mechanism 1034, the first domain controller 1021 is connected with the first door lock mechanism 1031 and the second door lock mechanism 1032 respectively, and the second domain controller 1022 is connected with the third door lock mechanism 1033 and the fourth door lock mechanism 1034 respectively. Then, after receiving the collision signal, the first domain controller 1021 can drive the first door lock mechanism 1031 and the second door lock mechanism 1032 to perform the unlocking of the vehicle door based on the collision signal; and the second domain controller 1021 can drive the third door lock mechanism 1033 and the fourth door lock mechanism 1034 to perform the unlocking of the vehicle door based on the collision signal.

[0201] In some embodiments, if the plurality of domain controllers 102 further include a third domain controller 1023, the third domain controller 1023 and the first domain controller 1021 are connected by at least two third lines respectively, and the first domain controller 1021 can send the received collision signal to the third domain controller 1023 through each third line after receiving the collision signal, so that the third domain controller 1023 drives the door lock mechanism 103 connected therewith to perform the unlocking of the vehicle door based on the collision signal.

[0202] In some embodiments, if the third domain controller 1023 and the second domain controller 1022 are connected by a fourth line, the third domain controller 1023 can send the received collision signal to the second domain controller 1022 through the fourth line, so that the second domain controller 1022 drives the door lock mechanism 103 connected therewith to perform the unlocking of the vehicle door based on the collision signal; or, the third domain controller 1023 receives the collision signal sent by the second domain controller 1022 through the fourth line, so that the third domain controller 1023 drives the door lock mechanism 103 connected therewith to perform the unlocking of the vehicle door based on the collision signal.

[0203] In some embodiments, if the plurality of door lock mechanisms 103 include a first door lock mechanism 1031, a second door lock mechanism 1032, a third door lock mechanism 1033, and a fourth door lock mechanism 1034, the first domain controller 1021 is connected with the first door lock mechanism 1031, the second domain controller 1022 is connected with the second door lock mechanism 1032, and the third domain controller 1023 is connected with the third door lock mechanism 1033 and the fourth door lock mechanism 1034 respectively. Then, after receiving the collision signal, the first domain controller 1021 can drive the first door lock mechanism 1031 to perform the unlocking of the vehicle door based on the collision signal; the second domain controller 1022 can drive the second door lock mechanism 1032 to perform the unlocking of the vehicle door based on the collision signal; and the third domain controller 1023 can drive the third door lock mechanism 1033 and the fourth door lock mechanism 1034 to perform the unlocking of the vehicle door based on the collision signal.

[0204] In some embodiments, if the first domain controller 1021 and the emergency call controller 104 are connected through at least two fifth lines respectively, then after receiving the collision signal, the first domain controller 1021 can send the collision signal to the emergency call controller 104 through each of the fifth lines respectively, so that the emergency call controller 104 outputs the emergency rescue information based on the collision signal.

[0205] In some embodiments, if any one of the plurality of domain controllers 102 includes an emergency call unit, then after the controller domain receives the collision signal, the emergency call unit can output the emergency rescue information based on the received collision signal.

[0206] In the vehicle collision unlocking method provided by the embodiments of the present application, the redundant transmission of the collision signal between the collision detection unit 101 and the domain controller 102, between each of the domain controllers 102, and between the domain controller 102 and the emergency call controller 104 improves the possibility of successfully unlocking the vehicle door and outputting the emergency rescue information when the vehicle is in collision, thereby improving the safety of the vehicle.
