DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] In addition, the description of "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the technical features or implicitly indicating the number of the indicated technical features. Therefore, the features with "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that those skilled in the art can realize it. When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection required by the present application.

[0025] The current new energy vehicle alarm system usually includes multiple alarm devices with different alarm functions, such as low-speed simulation alarm, turning alarm, blind area alarm, which can be used to remind the driver or outside traffic participants to pay attention to the vehicle state through sound and light, so as to reduce the probability of accidents; in order to realize the control of the above-mentioned low-speed simulation alarm, turning alarm, blind area alarm and the like, the above-mentioned alarm devices usually need to be connected with their corresponding controllers, control devices and the like related modules or devices through a connection harness, and the connection of the above-mentioned multiple alarm devices with their corresponding controllers, control devices and the like related modules or devices is independent of each other, that is, several alarm devices are connected with several alarm device lines, so it can be seen that the corresponding vehicle structure of the current vehicle alarm device installation scheme is complex, and the harness is numerous, and since the alarm device is usually connected with its corresponding controller, control device and the like related module or device through a CAN (Controller Area Network) harness, it is easy to be disturbed by the high-voltage line of the new energy vehicle, resulting in loss of control of the alarm device.

[0026] The new energy vehicle alarm system provided in the present application aims to simplify the structure of the vehicle alarm system, reduce the amount of harness, and at the same time, the communication harness which is not easy to be disturbed by the high-voltage line of the new energy vehicle can be used instead of the CAN harness, so as to reduce the interference of the high-voltage line of the new energy vehicle on the communication of the alarm device and enhance the stability of the vehicle alarm system.

[0027] Figure 1 The structure diagram of the new energy vehicle alarm system provided for an embodiment of the present application is shown in Figure 1 The new energy vehicle alarm system can include a cabin domain controller 15, a vehicle body domain controller 11, a power domain controller 14, a chassis module 12 and an integrated alarm device 13.

[0028] The integrated alarm device 13 is connected to one end of the chassis module 12, and the other end of the chassis module 12 is connected to the vehicle body domain controller 11; the cabin domain controller 15 and the power domain controller 14 are connected through the vehicle body domain controller 11, and the chassis module 12 is in communication connection with the integrated alarm device 13, wherein the integrated alarm device 13 at least integrates low-speed simulation alarm, turning alarm and blind area alarm functions.

[0029] For example, the integrated alarm 13 can be an alarm such as, but not limited to, a sound alarm, a sound and light alarm, and the like, which can issue an alarm sound, an alarm flash, and the like in accordance with a received signal, an instruction, and the like to alert a driver or a traffic participant outside the vehicle of a vehicle state. The cabin domain controller 15, the body domain controller 11, the power domain controller 14, the chassis module 12, and the like can be devices having functions such as a data processing function and a communication function, and the like, such as, but not limited to, an MCU (Microcontroller Unit), a VCU (Vehicle Control Unit), an ECU (Electronic Control Unit), and the like.

[0030] The integrated alarm 13 is connected to one end of the chassis module 12, and the other end of the chassis module 12 is connected to the body domain controller 11, which can mean a connection method including, but not limited to, a communication connection and / or an electrical connection, and the like. The communication connection can include, for example, a CANFD (Controller Area Network with Flexible Data rate) communication connection, a CAN communication connection, a PWM (Pulse Width Modulation) communication connection, and the like.

[0031] The cabin domain controller 15 and the power domain controller 14 are connected through the body domain controller 11, and the chassis module 12 and the integrated alarm 13 are communicatively connected, which can mean that the cabin domain controller 15 is communicatively connected to the integrated alarm 13 through the body domain controller 11 and the chassis module 12, and the power domain controller 14 is also communicatively connected to the integrated alarm 13 through the body domain controller 11 and the chassis module 12, that is, a communication connection relationship of the cabin domain controller 15 → the body domain controller 11 → the chassis module 12 → the integrated alarm 13 and the power domain controller 14 → the body domain controller 11 → the chassis module 12 → the integrated alarm 13 is formed.

[0032] The power domain controller 14 can obtain vehicle motion data such as vehicle high-voltage power-on state, vehicle current gear, and vehicle current speed through devices such as sensors, and send the vehicle motion data to the body domain controller 11 through the communication connection; the cabin domain controller 15 can obtain, through devices such as cameras and / or radars, for example, vehicle blind area obstacle distance information, and generate, for example, blind area warning level data in combination with, for example, a preset blind area warning level algorithm or a preset blind area warning level rule, and send the blind area warning level data to the body domain controller 11 through the communication connection. The blind area may, for example, include a left blind area, a right blind area, a front blind area, and a rear blind area, without limitation.

[0033] For example, the blind area warning level rule can divide the blind area warning level into, for example, general, more urgent, and very urgent according to the vehicle blind area obstacle distance information in the range of the left blind area, the right blind area, the front blind area, and the rear blind area. For example, when the obstacle distance of a certain blind area is detected to be ≤1.5 meters and >1 meter, the blind area warning level is general; when the obstacle distance of a certain blind area is detected to be ≤1 meter and >0.5 meter, the blind area warning level is more urgent; and when the obstacle distance of a certain blind area is detected to be ≤0.5 meter, the blind area warning level is very urgent. Of course, the above is only an example, and the specific blind area warning level rule can be adjusted and determined according to actual conditions, without limitation.

[0034] After receiving, for example, vehicle motion data from the power domain controller 14 and / or blind area warning level data from the cabin domain controller 15, the body domain controller 11 can generate, for example, warning mode request data in combination with, for example, a preset warning mode request algorithm or a preset warning mode request rule, and send the warning mode request data to the chassis module 12 through the communication connection. The chassis module 12 generates corresponding warning instructions according to the warning mode request data, and sends the warning instructions to the integrated alarm 13 through the communication connection, so as to control the integrated alarm 13 to alarm in the corresponding warning mode according to the warning instructions, for example, blind area warning and low-speed warning.

[0035] It can be understood that, in order to realize the communication connection, the cabin domain controller 15, the body domain controller 11, the power domain controller 14, the chassis module 12, and the integrated alarm 13 can have an interface for connecting a communication harness, which can support, for example, CANFD communication harness, CAN communication harness, PWM communication harness, and the like.

[0036] Of course, the above are all possible examples, the specific type, model, function, connection mode, etc. of the above cabin domain controller 15, vehicle body domain controller 11, power domain controller 14, chassis module 12 and integrated alarm 13, the specific acquisition mode, generation mode, etc. of the above data can be selected and determined according to the actual situation, and are not limited by the above. Figure 1 The content shown is only one possible connection mode, and the number of lines cannot represent the actual number of wire harnesses, nor can it be used as a basis for distinguishing connection modes, and the specific position relationship of the above devices or equipment is also not limited by the content shown. Figure 1 The content shown is not limited, and the specific wire harness arrangement and the specific position relationship of the above devices or equipment can be adjusted and determined according to the actual situation, and are not limited herein.

[0037] The alarm system of the new energy vehicle provided by the embodiment of the application comprises a cabin domain controller 15, a vehicle body domain controller 11, a power domain controller 14, a chassis module 12 and an integrated alarm 13. The integrated alarm 13 is connected to one end of the chassis module 12, and the other end of the chassis module 12 is connected to the vehicle body domain controller 11. The cabin domain controller 15 and the power domain controller 14 are connected through the vehicle body domain controller 11, and the chassis module 12 is in communication connection with the integrated alarm 13. The integrated alarm 13 at least integrates low-speed simulation alarm, turning alarm and blind area alarm functions. Only one integrated alarm 13 is connected to the cabin domain controller 15, the vehicle body domain controller 11, the power domain controller 14 and the chassis module 12 of the vehicle to form an alarm line, thereby realizing multiple alarm functions such as low-speed simulation alarm, turning alarm and blind area alarm, avoiding the need to set multiple alarms for different alarm functions, and connecting multiple alarms to the devices to form multiple lines, each line can only realize one corresponding alarm function, simplifying the structure of the vehicle alarm system and reducing the amount of wire harnesses.

[0038] Optionally, on the basis of the embodiment, the alarm system can further comprise an electronic brake controller 21. Figure 1 The electronic brake controller 21 is connected through the vehicle body domain controller 11, and the chassis module 12 is in communication connection with the integrated alarm 13.

[0039] For example, the electronic brake controller 21 is connected through the vehicle body domain controller 11, and the chassis module 12 is in communication connection with the integrated alarm 13, which means that the electronic brake controller 21 is in communication connection with the integrated alarm 13 through the vehicle body domain controller 11 and the chassis module 12, that is, the communication connection relationship of the electronic brake controller 21→vehicle body domain controller 11→chassis module 12→integrated alarm 13 is formed.

[0040] The electronic brake controller 21 can obtain vehicle braking data, for example, by means of sensors, etc., and send the vehicle braking data to the body domain controller 11 via the communication connection. The vehicle braking data can include, for example, the current vehicle speed, which is important data. The power domain controller 14 and the electronic brake controller 21 can each independently obtain the current vehicle speed and send it to the body domain controller 11 via the communication connection to achieve data acquisition redundancy. It can be understood that in addition to the current vehicle speed, there can be other important data, and other important data can also be obtained by similar data acquisition redundancy to improve the reliability of important data acquisition.

[0041] In the above embodiment, the body domain controller 11 can also generate alarm mode request data, such as a preset alarm mode request algorithm or a preset alarm mode request rule, after receiving vehicle braking data from the electronic brake controller 21, and send the alarm mode request data to the chassis module 12 via the communication connection. The chassis module 12 can generate corresponding alarm instructions according to the alarm mode request data and send the alarm instructions to the integrated alarm 13 via the communication connection, so as to control the integrated alarm 13 to alarm according to the corresponding alarm mode of the alarm instructions, for example, low-speed alarm, etc. Figure 1 In the above embodiment, the body domain controller 11 can also generate alarm mode request data, such as a preset alarm mode request algorithm or a preset alarm mode request rule, after receiving vehicle braking data from the electronic brake controller 21, and send the alarm mode request data to the chassis module 12 via the communication connection. The chassis module 12 can generate corresponding alarm instructions according to the alarm mode request data and send the alarm instructions to the integrated alarm 13 via the communication connection, so as to control the integrated alarm 13 to alarm according to the corresponding alarm mode of the alarm instructions, for example, low-speed alarm, etc.

[0042] Further, based on the above embodiment, the alarm system can further include a surround view camera module 22, and the surround view camera module 22 is in communication connection with the cabin domain controller 15. Figure 1

[0043] ​For example, the surround-view camera module 22 may include multiple cameras, which may be set at different locations in the vehicle to monitor the surroundings of the vehicle. The cockpit domain controller 15 may acquire information such as the distance to obstacles in the vehicle's blind spots through the cameras and / or radar. In other words, the cockpit domain controller 15 may acquire information such as the distance to obstacles in the vehicle's blind spots through the cameras included in the surround-view camera module 22. The surround-view camera module 22 and the cockpit domain controller 15 may be connected in communication, for example, through video transmission protocols including but not limited to RTMP (Real Time Messaging Protocol), RTSP (Real Time Streaming Protocol), RTP (Real-time Transport Protocol), and HLS (HTTP Live Streaming) (HTTP-based adaptive bitrate streaming media transmission protocol).

[0044] Of course, the above are just possible examples. The specific type, model, and function of the surround-view camera module 22, as well as the specific communication connection between the surround-view camera module 22 and the cockpit domain controller 15, can be selected and determined according to the actual situation, and are not limited to the above.

[0045] In addition, Figure 1 Based on the embodiments, the alarm system may further include: a turn signal module 23; the turn signal module 23 and the chassis module 12 are electrically connected via pins.

[0046] For example, the chassis module 12 can obtain the power-on state of the pin through a sensor or the like, and obtain data including but not limited to turn signal state data, and send the data to the body domain controller 11 and the cabin domain controller 15 through the communication connection. After receiving the data such as the turn signal state data from the chassis module 12, the cabin domain controller 15 can feed back the turn signal state to the driver through an instrument panel or the like in the cabin. After receiving the data such as the turn signal state data from the chassis module 12, the body domain controller 11 can generate alarm mode request data in combination with a preset alarm mode request algorithm or a preset alarm mode request rule, and send the alarm mode request data to the chassis module 12 through the communication connection. The chassis module 12 generates corresponding alarm instructions according to the alarm mode request data, and sends the alarm instructions to the integrated alarm 13 through the communication connection, so as to control the integrated alarm 13 to alarm in the corresponding alarm mode according to the alarm instructions, for example, turn alarm.

[0047] Further, based on the embodiment, the alarm system can further include a high beam module 23, and the high beam module 23 and the chassis module 12 are electrically connected through a pin. Figure 1

[0048] For example, similar to the above embodiment, the chassis module 12 can obtain the power-on state of the pin through a sensor or the like, and obtain data including but not limited to high beam state data, and send the data to the body domain controller 11 and the cabin domain controller 15 through the communication connection. After receiving the data such as the high beam state data from the chassis module 12, the cabin domain controller 15 can feed back the high beam state to the driver through an instrument panel or the like in the cabin. After receiving the data such as the high beam state data from the chassis module 12, the body domain controller 11 can generate alarm mode request data in combination with a preset alarm mode request algorithm or a preset alarm mode request rule, and send the alarm mode request data to the chassis module 12 through the communication connection. The chassis module 12 generates corresponding alarm instructions according to the alarm mode request data, and sends the alarm instructions to the integrated alarm 13 through the communication connection, so as to control the integrated alarm 13 to alarm in the corresponding alarm mode according to the alarm instructions, for example, high beam state alarm.

[0049] Optionally, based on the embodiment, the alarm system can further include a low beam module 24, and the low beam module 24 and the chassis module 12 are electrically connected through a pin. Figure 1 ​On the basis of the embodiment, the alarm system can further include a terminal device 25 connected to the body domain controller 11, and the chassis module 12 and the integrated alarm 13 are in communication connection.

[0050] For example, the terminal device 25 can be a computer, a server, or other device with communication and data processing functions. It can be placed in a server room, such as a vehicle data center or a brand customer service center. The terminal device 25 is connected to the body domain controller 11, and the chassis module 12 and the integrated alarm 13 are in communication connection. For example, the terminal device 25 can be connected to the body domain controller 11 through a wireless network connection protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol) protocol, and then form a communication connection relationship of terminal device 25→body domain controller 11→chassis module 12→integrated alarm 13 through the body domain controller 11.

[0051] The chassis module 12 generates corresponding alarm instructions according to the alarm mode request data, and sends the alarm instructions to the integrated alarm 13 through communication connection. At the same time, the alarm instructions can also be sent to the terminal device 25 through the body domain controller 11, so as to realize cloud recording of the alarm instructions, such as correctness judgment and accuracy judgment of the alarm instructions.

[0052] Of course, the above content is only an example. The specific type, model, function, setting location, connection method of the terminal device 25, and the use of cloud recording of the alarm instructions can be determined according to the actual situation, and are not limited herein.

The specific position relationship of each device or equipment is also not limited to Figure 2The content shown is limited, and the specific wiring arrangement and the specific positional relationship of the above devices or equipment can be adjusted and determined according to the actual situation, which is not limited here.

[0054] Optionally, in Figure 1 On the basis of the above-mentioned embodiment, the communication connection between the above-mentioned cabin domain controller 15 and the above-mentioned vehicle body domain controller 11, the communication connection between the above-mentioned vehicle body domain controller 11 and the above-mentioned chassis module 12 are all through the first preset communication protocol, and the communication connection between the above-mentioned chassis module 12 and the above-mentioned integrated alarm 13 is through the second preset communication protocol.

[0055] Further, on the basis of the above-mentioned embodiment, the first preset communication protocol may, for example, be the CAN communication protocol, and the second preset communication protocol may, for example, be the PWM communication protocol.

[0056] However, it can be understood that the above content is only an example, and the specific first and second preset communication protocols can be selected and determined according to actual needs, and are not limited by the above content.

[0057] In addition, in Figure 1 On the basis of the above-mentioned embodiment, the communication connection between the above-mentioned power domain controller 14 and the above-mentioned vehicle body domain controller 11 can be through the CANFD communication protocol.
