Description

Technical Field

[0001] The present invention relates to the automotive field, and in particular to a fused wading mode detection control method and system. Background Art

[0002] With the development of science and technology, the demand for car wading capability is gradually increasing. Car wading mode detection refers to the use of vehicle sensors and control systems to monitor and adjust the state of the car when driving in a wading environment, ensuring that the vehicle can drive safely in deep water or on uneven roads. This mode is usually used in muddy roads, flooded roads or similar water environments to prevent water ingress, engine stalling or other dangers during the wading process.

[0003] However, when the existing technology detects the wading mode, it is often necessary to add a water level sensor, which increases the cost of use and is difficult to deploy. Summary of the invention

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a fused wading mode detection control method and system, aiming to reduce the cost of wading mode detection and ensure the safety of drivers and vehicles.

[0005] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solution:

[0006] According to a first aspect of the present invention, a fused wading mode detection and control method is provided, comprising the following steps:

[0007] In step 1, water level image information is collected through a camera, and the water level image information can reflect the position information of water on the vehicle body and wheels;

[0008] In step 2, the water level image information is input to the ADCU of the intelligent driving domain control system, and the water level height information is obtained through calculation;

[0009] In step 3, based on the water level information, determine whether the water level exceeds the warning line:

[0010] If not, maintain the status quo;

[0011] If so, the CAN bus is used to input to the hybrid control unit HCU and the air suspension control unit to activate the wading mode;

[0012] Activating Wading Mode raises the vehicle's body and:

[0013] If the vehicle is a gasoline vehicle, the engine remains running;

[0014] If the vehicle is a new energy vehicle, start the engine.

[0015] Preferably, the camera is a 360-degree panoramic imaging camera.

[0016] According to a second aspect of the present invention, a fused wading mode detection and control system is provided, comprising a camera module, a calculation and judgment module, and an execution module.

[0017] The camera module is used to collect water level image information through the camera, and the water level image information can reflect the position information of water on the vehicle body and wheels;

[0018] The calculation and judgment module is used to obtain water level information through calculation and determine whether the water level exceeds the warning line:

[0019] If not, maintain the status quo;

[0020] If so, the instruction execution module activates the wading mode.

[0021] The execution module is used to activate the wading mode by inputting the instructions of the calculation and judgment module to the hybrid control unit HCU and the air suspension control unit through the CAN bus. After the wading mode is activated, the vehicle body will be raised. At the same time: if the vehicle is a gasoline vehicle, the engine will keep running; if the vehicle is a new energy vehicle, the engine will be started.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This embodiment achieves the purpose of adding new functions through special control logic, only using existing hardware, and through image recognition and position comparison algorithms. This method based on real-time data calculation and judgment can more flexibly and intelligently deal with complex wading situations, reduce costs, and improve driving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Other features, objects and advantages of the present invention will become more apparent from the detailed description of non-limiting embodiments made with reference to the following drawings:

[0025] Figure 1 Schematic diagram of the process described in Example 1. DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0028] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, all directional indications in this application (such as up, down, left, right, front, back, bottom...) are only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] Example 1

[0030] This embodiment provides a fusion wading mode detection and control method, which integrates multiple advanced technologies and ensures the safety of the vehicle in a wading environment by combining sensors, computing control and intelligent decision-making systems.

[0031] The method provided in this embodiment is as follows Figure 1 As shown, it includes the following steps:

[0032] In step 1, the camera collects water level image information, which can reflect the location information of water on the vehicle body and wheels. In this step, the system can identify multi-dimensional information such as water coverage area, depth, flow rate, etc. through visual sensors, providing more data support for subsequent intelligent decision-making.

[0033] Furthermore, the camera may be a 360-degree panoramic imaging camera to improve the accuracy and comprehensiveness of position information determination.

[0034] In step 2, the water level image information is input to the ADCU of the intelligent driving domain control system, and the water level height information is obtained through calculation. This step combines image data with intelligent calculation, so that the water level judgment does not only rely on simple sensors, but also uses image processing technology to analyze the position of water on the car body and wheels in the water level image information, so as to perform more accurate analysis and calculate the water level height.

[0035] In step 3, determine whether the water level exceeds the warning line:

[0036] If not, maintain the status quo;

[0037] If so, the CAN bus is used to input the hybrid control unit HCU and the air suspension control unit, and the wading mode is activated at this time. This automation greatly reduces the difficulty of operation for the driver, especially in harsh wading environments, and can improve driving safety and ensure the safety of the driver and the vehicle.

[0038] Specifically, after activating the wading mode, the vehicle body will be raised. At the same time: if the vehicle is a gasoline vehicle, the engine will remain running; if the vehicle is a new energy vehicle, the engine will be started.

[0039] This embodiment achieves the purpose of adding new functions through special control logic, only using existing hardware, and through image recognition and position comparison algorithms. This method based on real-time data calculation and judgment can more flexibly and intelligently deal with complex wading situations, reduce costs, and improve driving safety.

Specifically, the system provided by this embodiment includes a camera module, a calculation and judgment module, and an execution module. Among them:

[0042] The camera module is used to collect image information through a camera, and the image information can reflect the position information of water on the vehicle body and wheels. Further, the camera can be a 360-degree panoramic image camera.

[0043] The calculation and judgment module is used to obtain water level information through calculation and determine whether the water level exceeds the warning line:

[0044] If not, maintain the status quo;

[0045] If so, the instruction execution module activates the wading mode.

[0046] The execution module is used to activate the wading mode by inputting the instructions of the calculation and judgment module to the hybrid control unit HCU and the air suspension control unit through the CAN bus. After the wading mode is activated, the vehicle body will be raised. At the same time: if the vehicle is a gasoline vehicle, the engine will keep running; if the vehicle is a new energy vehicle, the engine will be started.

[0047] It should be pointed out that the explanation of the implementation method and beneficial effects of the method in the above-mentioned embodiment 1 is also applicable to this embodiment, and will not be elaborated in detail here to avoid redundancy.
