[0031] With reference to the drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts should fall within the scope of the present application.

[0032] The exemplary embodiments will be described in detail herein below with reference to the drawings. The following description is presented with reference to the drawings, in which the same numbers indicate the same or similar elements throughout the several drawings. The embodiments described in the following exemplary embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0033] Figure 1 is a structural schematic diagram of the trailer control system provided by the embodiments of the present application. With reference to Figure 1 The trailer control system provided by the embodiments of the present application comprises:

[0034] The trailer connector 11 is configured to connect or disconnect the towing vehicle and the towed vehicle. Illustratively, the trailer connector 11 may, for example, be any device capable of connecting or disconnecting the towing vehicle and the towed vehicle, and enabling power transmission, power transmission, signal transmission between the towing vehicle and the towed vehicle when connected; the towing vehicle may, for example, be any vehicle capable of providing power, power, control signals to the towed vehicle connected thereto; the towed vehicle may, for example, be any vehicle capable of being connected to the towing vehicle and capable of utilizing the power, power, control signals provided by the towing vehicle in any form.

[0035] In some embodiments, the trailer connector 11 may, for example, include a socket and a plug, the socket may, for example, be detachably provided at the tail of the towing vehicle, and the plug may, for example, be detachably provided at the head of the towed vehicle; the plug and the socket may, for example, be respectively provided with corresponding pins, and the towing vehicle and the towed vehicle may be connected by connecting the plug and the socket, and aligning the corresponding pins in the plug and the socket to perform power transmission, power transmission, signal transmission, etc.

[0036] The trailer control module 12 is configured to detect connection state information of the trailer connector 11, determine valid information in the connection state information, and control the sub-area controller 13 to adjust different functional modules of the towing vehicle according to the valid information, where the valid information is used to indicate the real use intention of the trailer connector 11. As described above, the trailer connector 11 can include a socket arranged at the tail of the towing vehicle and a plug arranged at the head of the towed vehicle, and the connection state information of the trailer connector 11 can be used to indicate, but not limited to, whether the plug and the socket are connected. Considering that the trailer connector 11 may be misconnected or disconnected during use, the trailer control module 12 of the embodiment of the present application can further determine the valid information in the connection state information to further identify the real use intention of the trailer connector 11.

[0037] As described above, the towing vehicle and the towed vehicle can be connected by the socket and the plug, and the corresponding pins in the socket and the plug are aligned to perform power transmission, power transmission, signal transmission, etc. In view of this, in some embodiments, the trailer control module 12 detects the connection state information of the trailer connector 11, for example, by detecting the validity of the voltage level on the pins of the plug or the socket. For example, when the voltage level detected on the pins 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 state information corresponding to the connection state of the trailer connector 11 is generated; when no voltage level meeting the expected signal requirements is detected on the pins of the plug or the socket, it is determined that the trailer connector 11 is in a disconnected state, and then the connection state 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 misconnected during use, each connection of the trailer connector 11 can be determined as a valid connection. In some embodiments, the connection state information of the trailer connector 11 can include, for example, first connection state information indicating that the trailer connector 11 is in a connected state, and the trailer control module 12 can be configured to determine the first connection state information as first valid information in response to detecting the first connection state information when determining the valid information in the connection state information. The first valid information is used to indicate a first connection intention of expecting the trailer connector 11 to enable the towing vehicle and the towed vehicle to perform power transmission.

[0039] As described above, the trailer connector 11 can enable power transmission, electrical power transmission, signal transmission, etc. between the towing vehicle and the towed vehicle. In addition, when the trailer connector 11 is in the connected state, the signal transmission between the towing vehicle and the towed vehicle can 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 the connected state, the trailer control module 12 can further test the signal transmission between the towing vehicle and the towed vehicle, and determine whether the connection state information of the trailer connector 11 is valid according to the test result, so as to further ensure the reliability and safety of the trailer operation.

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

[0041] In addition, when the trailer connector 11 is in the connected state, the towing vehicle can tow the towed vehicle through the trailer connector 11. In view of this, the connection state of the trailer connector 11 can be disconnected due to non-use intention caused by road conditions, environment, etc. In view of this, when the trailer connector 11 changes from the connected state to the disconnected state, the trailer control module 12 can determine whether the connection state information of the trailer connector 11 is valid according to the vehicle state information of the towing vehicle, so as to avoid the influence of the disconnection of the trailer connector 11 caused by non-use intention on the trailer operation.

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

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

[0044] The sub-domain controller 13 is configured to adjust different functional modules of the towing vehicle according to the valid information, so that the different functional modules of the towing vehicle are adapted to the trailer scene or the non-trailer scene. Optionally, the trailer scene is used to indicate a scene in which the towing vehicle is connected with the towed vehicle and the towing vehicle is towing the towed vehicle to move, and the non-trailer scene is used to indicate a scene in which the towing vehicle is not connected with the towed vehicle. In the trailer scene, since the actual load of the power-providing towing vehicle, the vehicle length, etc. change, it is necessary to adjust the different functional modules of the towing vehicle to meet the requirements of the different functional modules of the towing vehicle in the trailer scene. Illustratively, the sub-domain controller 13 may, for example, include a controller arranged in the towing vehicle and independently controlling different functional modules of the towing vehicle.

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

[0046] In view of the fact that in the trailer scenario, the towed vehicle will block the tail lights of the towing vehicle, so that the tail lights of the towing vehicle can not play the role of lighting, signal indication, etc., and will interfere with the sight line of the towed vehicle. In view of this, when in the trailer scenario, that is, the trailer connector 11 is in the connected state, the body light function module of the towing vehicle can be adjusted by the sub-domain controller 13 provided in the towing vehicle, so that the body light function module of the towing vehicle is adapted to the trailer scenario, and the safety of the trailer operation in the trailer scenario is ensured. 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, and the sub-domain controller 13 may, for example, be configured to adjust the body light function module according to the first valid information to disable the tail lights of the towing vehicle when adjusting different function modules of the towing vehicle according to the valid information.

[0047] In order to ensure the safety of the trailer operation in the trailer scenario, when the tail lights of the towing vehicle need to be turned on, the tail lights of the towed vehicle can be turned on by the trailer control module 12 to realize the functions of lighting, signal indication, etc. 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, be further configured to receive a first request for turning on the tail lights of the towing vehicle; and 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 tail lights of the towed vehicle.

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

[0049] To meet the braking demand of the towing vehicle and the towed vehicle in the towing scenario, in some embodiments, the second sub-area controller can 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 can be configured to, according to the second request, generate a second trailer control 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-area controller 13 of the towing vehicle can further include a third sub-area controller for adjusting the instrument display function module of the towing vehicle. When adjusting different function modules of the towing vehicle according to the valid information, the sub-area controller 13 can be configured to generate prompt information according to the first valid information. The prompt information can be used to, but not limited to, prompt the connection state information of the trailer connector 11 and / or the adjustment of different function modules of the towing vehicle by the sub-area controller 3.

[0051] In some embodiments, when in the non-towing scenario, i.e., the trailer connector 11 changes from the connected state to the disconnected state, when adjusting different function modules of the towing vehicle according to the valid information, the sub-area controller 13 can be configured to adjust different function modules of the towing vehicle according to the second valid information, so that different function modules of the towing vehicle adapt to the non-towing scenario.

[0052] The present application detects the connection state information of the trailer connector through the trailer control module, can capture the possible towing scenarios of the vehicle according to the connection state information, and then determines the valid information in the connection state information for indicating the real use intention of the trailer connector through the trailer control module, so that the valid scenarios in all possible towing scenarios of the vehicle can be identified according to the valid information, to avoid invalid adjustments of different function modules of the vehicle in invalid scenarios such as misconnection or misdisconnection of the trailer connector, greatly improving the safety and reliability in the towing scenario or the non-towing scenario.
