Description

Technical Field

[0001] The present invention relates to the technical field of amphibious vehicles, and in particular to a lighting control system suitable for amphibious vehicles. Background Art

[0002] An amphibious vehicle is a specialized vehicle that combines the capabilities of both a car and a boat, capable of both driving on land like a car and floating on water like a boat. Because the lighting systems of vehicles traveling on land must comply with regulatory requirements, the exterior lights of amphibious vehicles are mounted low. When the vehicle is traveling on water, these lights are typically submerged in water. To continue using these lights for illumination during the water-based mode, they must possess high levels of waterproofing and corrosion resistance. However, since the lights are submerged, lighting them does not provide illumination for the vehicle's water-based mode. This wastes energy, can cause battery damage, and poses the risk of short circuits due to water intrusion.

[0003] Currently, amphibious vehicles utilize a separate water-based lighting system installed on the upper body of the vehicle, with two separate control switch systems controlling the vehicle's onshore and underwater lighting modes. However, this approach has several drawbacks: 1. The cab's lighting-related control switches are numerous, resulting in high costs; 2. There is a risk of misoperation that could lead to incorrect switching between amphibious and underwater modes; 3. The lighting system's wiring harness is complex, preventing timely protection from seawater corrosion and hindering troubleshooting.

[0004] Therefore, it is necessary to provide a lighting control system suitable for amphibious vehicles, which can control the land mode lighting and water mode lighting of amphibious vehicles through the same lighting control system, simplify the operation of the control system, reduce the cost of use, and facilitate maintenance work.

[0038] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0039] Existing amphibious vehicles typically utilize two lighting control systems. The driver manually selects the vehicle's driving mode, and the corresponding control systems control the vehicle's lighting. This results in numerous lighting-related control switches and a complex wiring harness within the cab. Since mode switching and lighting control are entirely manual, the operation is extremely complex and poses a significant risk of misoperation. Therefore, the present invention utilizes a single lighting control system to uniformly control the vehicle's lighting in both water and land driving modes, simplifying the cab's wiring harness design. Furthermore, by automatically determining the vehicle's driving mode, the lighting control process is simplified, improving vehicle safety and ease of operation.

[0040] The embodiment of the present invention provides a lighting control system suitable for amphibious vehicles. Figure 1 This is a structural diagram of an embodiment of a lighting control system 100 for amphibious vehicles provided by the present invention, comprising: a state acquisition module 101, a signal processing module 102 and a load execution module 103;

[0041] The state acquisition module 101 is used to acquire vehicle operation mode information and vehicle driving state information, and send the vehicle operation mode information and vehicle driving state information to the signal processing module 102;

[0043] The load execution module 103 is configured to receive the light control instruction sent by the signal processing module 102 and perform light control on the vehicle according to the light control instruction.

[0044] The lighting control system for amphibious vehicles provided in this embodiment acquires vehicle operating mode information and vehicle driving status information through a status acquisition module. A signal processing module determines the vehicle's road conditions based on the vehicle's operating mode and generates lighting control instructions based on the road conditions and vehicle driving status information. A load execution module controls the vehicle's lighting according to the lighting control instructions. This embodiment uses the same lighting control system to control the vehicle's lighting status in different operating modes, simplifying cab wiring design. The ability to generate corresponding lighting control instructions based on the vehicle's driving status in different operating modes eliminates the need to manually select the vehicle's operating mode and then use the corresponding control system to control the vehicle's lighting. This greatly simplifies driver operation and avoids the risk of system damage due to misoperation.

[0056] Since vehicles need to meet relevant regulatory design requirements when driving on land, the land lighting unit is used to control the lighting of the vehicle in different driving states such as braking, reversing, steering and lighting in the land driving mode; when the vehicle is in the water driving mode, the land lighting unit will be immersed in seawater and cannot provide lighting or light indication services for the vehicle. Therefore, the land lighting unit needs to be turned off and protected by a protective unit to prevent the land lighting unit from being eroded by seawater and to prevent seawater from entering and causing a short circuit and damage to the control system.

The multifunctional lighting unit is used to complete lighting tasks in special situations such as field search and warning lighting according to alarm light control instructions.

[0059] It should be noted that, in the land driving mode, the system turns off the water lighting unit and chooses whether to turn on the multifunctional lighting unit according to demand.

[0064] The position sensor 305 is used to obtain the position information of the search light 301 and send the position information to the main control circuit 303;

[0069] As a specific embodiment, when turning left or right is required, the first preset steering angle is 45 degrees, the first preset light color is amber, and the first preset flashing frequency is 20 times per second. The search light is used to execute the corresponding steering angle, light color, and flashing frequency to complete the vehicle's turn signal indication operation in the water operation mode.

[0070] As a preferred embodiment, when the communication circuit 306 receives the reversing light control instruction sent by the signal processing module 102, the rotation control instruction sent by the main control circuit 303 includes the second preset steering angle, and the display control instruction is the second preset light color.

[0073] As a preferred embodiment, the state acquisition module 101 is further configured to acquire function diagnosis request information and send the function diagnosis request information to the signal processing module 102;

[0074] The signal processing module 102 is further configured to perform fault diagnosis on the load execution module 103 according to the function diagnosis request information to obtain a fault diagnosis result.

[0075] As a preferred embodiment, the signal processing module 102 performs fault diagnosis on the load execution module 103 according to the function diagnosis request information, including: voltage status diagnosis and communication status diagnosis;

[0083] In some embodiments, after the BCM receives the vehicle operating mode information sent by the status acquisition module 101, it will send a confirmation message to the vehicle CAN network, allowing the driver to reconfirm the vehicle mode switching information. If the vehicle CAN network feeds back a confirmation response, the BCM uses the lighting control instructions in the corresponding mode to control the vehicle lighting.
