Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0033] Figure 1 Schematic diagram of the structure of the trailer control system provided by the embodiment of the present application. Figure 1 , the trailer control system provided in the embodiment of the present application includes:

[0034] The trailer connector 11 is configured to connect or disconnect the towing vehicle and the towed vehicle. Schematically, the trailer connector 11 can be, for example, any device that can connect or disconnect the towing vehicle and the towed vehicle, and enable the towing vehicle and the towed vehicle to transmit power, electricity, and signals when connected; the towing vehicle can be, for example, any vehicle that can provide power, electricity, and control signals to the towed vehicle connected to itself; and the towed vehicle can be, for example, any vehicle that can be connected to the towing vehicle and can use the power, electricity, and control signals provided by the towing vehicle in any form.

[0035] In some embodiments, the trailer connector 11 may include a socket and a plug, for example. The socket may be detachably arranged at the rear of the towing vehicle, and the plug may be detachably arranged at the front of the towed vehicle. The plug and the socket may be respectively provided with corresponding pins, for example. The towing vehicle and the towed vehicle may transmit power, electricity, signals, etc. by connecting the plug and the socket and aligning the corresponding pins in the plug and the socket.

[0036] The trailer control module 12 is configured to detect the connection status information of the trailer connector 11; determine the valid information in the connection status information, and control the sub-domain controller 13 to adjust the different functional modules of the towing vehicle according to the valid information, and the valid information is used to indicate the actual use intention of the trailer connector 11. As mentioned above, the trailer connector 11 may include a socket arranged at the rear of the towing vehicle and a plug arranged at the front of the towed vehicle. The connection status information of the trailer connector 11 can be used for but not limited to indicating whether the plug and the socket are connected. Considering that the trailer connector 11 may be connected or disconnected by mistake during use. In view of this, the trailer connector 11 of the embodiment of the present application can also determine the valid information in the connection status information to further identify the actual use intention of the trailer connector 11.

[0037] As mentioned above, the towing vehicle and the towed vehicle can perform power transmission, electric power transmission, signal transmission, etc. by connecting the socket and the plug and aligning the corresponding pins in the socket and the plug. In view of this, in some embodiments, the trailer control module 12 detects the connection status information of the trailer connector 11, for example, by detecting the validity of the voltage level on the pin of the plug or the socket. For example, when the voltage level detected on the pin of the plug or the socket meets the expected signal requirements, it is determined that the trailer connector 11 is in a connected state, and then the connection status information corresponding to the connection state of the trailer connector 11 is generated; when the voltage level that meets the expected signal requirements is not detected on the pin of the plug or the socket, it is determined that the trailer connector 11 is in a disconnected state, and then the connection status information corresponding to the disconnected state of the trailer connector 11 is generated.

[0038] Considering that the trailer connector 11 is less likely to be connected by mistake during use. In view of this, each connection of the trailer connector 11 can be determined as a valid connection. In some embodiments, the connection status information of the trailer connector 11 can include, for example, first connection status information indicating that the trailer connector 11 is in a connected state, and the trailer control module 12 can be configured to, for example, determine the first connection status information as first valid information in response to detecting the first connection status information when determining the valid information in the connection status information. The first valid information is used to indicate the first connection intention of the trailer connector 11 to enable the towing vehicle and the towed vehicle to transmit power.

[0039] As mentioned above, the trailer connector 11 can enable power transmission, electric power transmission, signal transmission, etc. between the towing vehicle and the towed vehicle. Considering that when the trailer connector 11 is in a connected state, the signal transmission between the towing vehicle and the towed vehicle may be disturbed due to equipment failure, improper operation, environmental factors, etc., thereby affecting the trailer operation. In view of this, when the trailer connector 11 is in a connected state, the signal transmission between the towing vehicle and the towed vehicle can be further tested by the trailer control module 12, and whether the connection status information of the trailer connector 11 is valid can be determined based on the test results, so as to further ensure the reliability and safety of the trailer operation.

[0040] In some embodiments, the connection status information of the trailer connector 11 may include, for example, first connection status information for indicating that the trailer connector 11 is in a connection state. When the trailer control module 12 determines the valid information in the connection status information of the trailer connector 11, for example, it may be configured to: send test information to the towed vehicle in response to detecting the first connection status information; if positive feedback information of the test information is received, determine the first connection status information corresponding to the test information as the first valid information. The test information may be used to confirm whether the signal transmission between the towing vehicle and the towed vehicle is normal; the positive feedback information of the test information may be used to indicate that the signal transmission between the towing vehicle and the towed vehicle is normal; and the first valid information is used to indicate the intention to connect the trailer connector 11.

[0041] It is also considered that when the trailer connector 11 is in a connected state so that the towing vehicle can tow the towed vehicle through the trailer connector 11, the connection state of the trailer connector 11 may be affected by factors such as road conditions and environment, resulting in disconnection without the intention of use. In view of this, when the trailer connector 11 changes from a connected state to a disconnected state, the trailer control module 12 may also determine whether the connection state information of the trailer connector 11 is valid based on the vehicle state information of the towing vehicle, so as to avoid the influence of the disconnection of the trailer connector 11 caused by the unintentional use on the trailer operation.

[0042] In some embodiments, the connection state information of the trailer connector 11 may include, for example, second connection state information for indicating that the trailer connector 11 changes from a connection state to a disconnection state. When determining valid information in the connection state information of the trailer connector 11, the trailer control module 12 may be configured to, for example, obtain vehicle state information related to the towing vehicle in response to detecting the second connection state information; if the vehicle state information satisfies the disconnection condition, determine the second connection state information corresponding to the vehicle state information as the second valid information. The second valid information is used to indicate the intention to disconnect the trailer connector 11.

[0043] In some embodiments, the vehicle status information related to the towing vehicle may include, for example, the power gear information and / or the vehicle speed information of the towing vehicle, and the disconnection condition may include, for example, a first disconnection condition for indicating that the power gear of the towing vehicle is a closed gear and a second disconnection condition for indicating that the vehicle speed of the towing vehicle is less than a vehicle speed threshold. When determining the valid information in the connection status information, the trailer control module 12 may be configured, for example, as follows: if the power gear information satisfies the first disconnection condition and / or the vehicle speed information satisfies the second disconnection condition, then the second connection status information corresponding to the power gear information is determined as the second valid information, or the second connection status information corresponding to the vehicle speed information is determined as the second valid information, or the second connection status information corresponding to the power gear information and the vehicle speed information is determined as the second valid information. For example, when the power level information satisfies the first disconnection condition, the second connection status information corresponding to the power level information can be determined as the second valid information, or when the vehicle speed information satisfies the second disconnection condition, the second connection status information corresponding to the vehicle speed information can be determined as the second valid information; or when the power level information satisfies the first disconnection condition and the vehicle speed information satisfies the second disconnection condition, the second connection status information corresponding to the power level information and the vehicle speed information can be determined as the second valid information.

[0044] The sub-domain controller 13 is configured to adjust the different functional modules of the tractor vehicle according to the effective information so that the different functional modules of the tractor vehicle are adapted to the trailer scenario or the non-trailer scenario. Optionally, the trailer scenario is used to indicate a scenario in which the tractor vehicle is connected to the towed vehicle and the tractor vehicle tows the towed vehicle to move; the non-trailer scenario is used to indicate a scenario in which the tractor vehicle is not connected to the towed vehicle. In the trailer scenario, since the actual load of the tractor vehicle providing power, the vehicle length, etc. have changed, it is necessary to adjust the different functional modules of the tractor vehicle to meet the requirements for the different functional modules of the tractor vehicle in the trailer scenario. Schematically, the sub-domain controller 13 may, for example, include a controller that is arranged in the tractor vehicle and independently controls the different functional modules of the tractor vehicle.

[0045] In some embodiments, the sub-domain controller 13 and the trailer control module 12 can communicate through a central gateway disposed in the towing vehicle, for example, so that the sub-domain controller 13 can adjust different functional modules of the vehicle according to the effective information sent by the trailer control module 12 to indicate the actual usage intention of the trailer connector 11.

[0046] Considering that in the trailer scenario, the towed vehicle will block the taillights of the towing vehicle, so that the taillights of the towing vehicle may not be able to play the role of lighting, signal indication, etc., and will interfere with the line of sight of the towed vehicle. In view of this, when in the trailer scenario, that is, when the trailer connector 11 is in a connected state, the body light function module of the towing vehicle can be adjusted by the sub-domain controller 13 set in the towing vehicle, so that the body light function module of the towing vehicle is adapted to the trailer scenario, ensuring the safety of the trailer operation in the trailer scenario. In some embodiments, the sub-domain controller 13 may, for example, include a first sub-domain controller for adjusting the body light function module of the towing vehicle. When the sub-domain controller 13 adjusts different function modules of the towing vehicle according to valid information, for example, it can be configured to: adjust the body light function module according to the first valid information to disable the taillights of the towing vehicle.

[0047] In order to ensure the safety of trailer operation in the trailer scene, when the taillights of the towing vehicle need to be turned on, the taillights of the towed vehicle can be turned on through the trailer control module 12 to achieve functions such as lighting and signal indication. In view of this, in some embodiments, the sub-domain controller 13 of the towing vehicle may, for example, include a first sub-domain controller for adjusting the body light function module of the towing vehicle, and the first sub-domain controller may, for example, also be configured to: receive a first request for turning on the taillights of the towing vehicle; send the first request to the trailer control module 12. The trailer control module 12 may, for example, be configured to: generate a first trailer control request according to the first request; and send the first trailer control request to the towed vehicle. The first trailer control request is used to request the towed vehicle to turn on the taillights of the towed vehicle.

[0048] As mentioned above, the sub-domain controller 13 needs to adjust the different functional modules of the traction vehicle so that the different functional modules of the traction vehicle are adapted to the trailer scene or the non-trailer scene, thereby ensuring the safety in the trailer scene or the non-trailer scene. In some embodiments, when in the trailer scene, that is, the trailer connector 11 is in a connected state, the sub-domain controller 13 of the traction vehicle may also include, for example, a second sub-domain controller for adjusting the power functional module of the traction vehicle. When the sub-domain controller 13 adjusts the different functional modules of the traction vehicle according to the valid information, for example, it may be configured as follows: according to the first valid information, the power functional module of the traction vehicle is adjusted to adjust the ESP (Electronic Stability Program), IPB (Integrated Power Brake), and EPB (Electronic Parking Brake) functional parameters of the traction vehicle so that the power functional module of the traction vehicle is adapted to the trailer scene.

[0049] In order to meet the braking requirements of the towing vehicle and the towed vehicle in the trailer scenario, in some embodiments, the second domain controller may be further configured to: in response to receiving a second request for starting the braking system of the towing vehicle; send the second request to the trailer control module 12. The trailer control module 12 may be configured to: generate a second trailer control request according to the second request; and send the second trailer control request to the towed vehicle. The first trailer control request is used to request the towed vehicle to start the braking system of the towed vehicle.

[0050] In some embodiments, the sub-domain controller 13 of the tractor vehicle may further include, for example, a third sub-domain controller for adjusting the instrument display function module of the tractor vehicle. When the sub-domain controller 13 adjusts the different function modules of the tractor vehicle according to the valid information, for example, it may be configured to generate prompt information according to the first valid information. The prompt information may be used for, but is not limited to, prompting the connection status information of the trailer connector 11 and / or the adjustment of the different function modules of the tractor vehicle by the sub-domain controller 3.

[0051] In some embodiments, when in a non-trailer scenario, that is, when the trailer connector 11 changes from a connected state to a disconnected state, the domain controller 13 adjusts the different functional modules of the traction vehicle according to the valid information. For example, it can be configured as follows: adjust the different functional modules of the traction vehicle according to the second valid information so that the different functional modules of the traction vehicle are adapted to the non-trailer scenario.

[0052] The present application detects the connection status information of the trailer connector through the trailer control module, and can capture possible trailer scenarios of the vehicle based on the connection status information, and then determines the effective information in the connection status information for indicating the actual use intention of the trailer connector through the trailer control module, so that the effective scenarios of all possible trailer scenarios of the vehicle can be identified based on the effective information, so as to avoid invalid adjustments to different functional modules of the vehicle in invalid scenarios such as the trailer connector being connected or disconnected by mistake, thereby greatly improving the safety and reliability in trailer scenarios or non-trailer scenarios.
