[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Combined with attachment Figure 1-2 As shown, a control system for automatic lighting of a sanitation vehicle sweeping plate includes at least:

[0040] The rain light sensor, light switch, body domain controller, cockpit domain controller and body control module are connected to the body domain controller respectively, and the left and right sweep lights are connected to the body controller respectively through hard lines; the body control module is connected to the cockpit domain controller. Among them:

[0041] Light switch: As a vehicle lighting control component, it has an "automatic headlight gear" for the driver to set the automatic start logic of the vehicle's basic lighting, such as setting the command to turn on / off the automatic headlights. The command signal is received and processed by the vehicle body domain controller; it is linked to the automatic lighting method of the present invention.

[0042] Rain and light sensor: used to integrate ambient light intensity detection and rainfall detection functions, and monitor the operating environment lighting conditions in real time, such as low illumination at night and weakened light in rainy and foggy days. The lighting control provides real-time ambient light information as an important input for the automatic headlight control logic.

[0043] The large screen on the vehicle is a human-machine interface (HMI), which supports the driver to manually operate vehicle functions such as manually turning on and off the sweeping lights. However, the core of the present invention is automatic control without manual operation.

[0044] Sweeping brush lighting: A lighting fixture installed around the sweeping disc to illuminate the sweeping disc operation area and assist the driver in seeing the road surface cleanliness and surrounding environment.

[0045] The cockpit domain controller is used to report the upper body operation mode and operation type data to the body domain controller. In addition to integrating the relevant functions of the cockpit domain, it also integrates the upper body control logic strategy, which is responsible for controlling the logical timing of the sanitation vehicle's upper body mechanism actions, such as controlling the washing and sweeping work, road sweeping work, operation type (left sweep, right sweep, full sweep), etc.

[0046] The body domain controller (BDC) serves as the vehicle's core control unit. It receives signals from the rain and light sensors and the light switch position. Combined with data such as the bodywork operation mode and type provided by the cockpit domain controller, it uses a preset algorithm to determine and output sweep light control instructions. This direct control of the sweep light circuits ultimately activates the lights. The BDC's pre-set algorithm integrates the operation mode, type, and ambient light conditions transmitted by the cockpit domain controller to automatically determine the logical rules for the light group's on / off state.

[0047] The bodywork execution module: Based on instructions from the cockpit domain controller, it drives specific bodywork electrical loads to perform the physical actions required for bodywork operations. This module is responsible for driving the electrical mechanisms on the sanitation vehicle bodywork, such as turning solenoid valves on and off and relays on and off. It also provides feedback to the cockpit domain controller regarding driver failures.

[0048] Specifically, the control logic of this control system is as follows: the rain and light sensors and light switches communicate with the cockpit domain controller via the body domain controller, and the bodywork control module communicates with the cockpit domain controller. Data and command transmission are carried out between the two systems via onboard communication networks such as the CAN bus, LIN bus, and Ethernet. The light switch allows the driver to set commands, such as turning the automatic headlights on or off. This command signal is received and processed by the body domain controller. The rain and light sensors provide the body domain controller with real-time ambient light information, which serves as a key input for the automatic headlight control logic. The body domain controller combines the light switch setting information, ambient light information, and vehicle operating mode to determine whether the sweep light should be turned on or off, and issues this control command to the sweep light responsible for execution. The body domain controller directly controls the sweep light circuit (turning it on or off) to execute the final light switching operation. The cockpit domain controller also manages the functional logic for bodywork operations, controlling functions related to bodywork cleaning and lifting, and issues commands to the bodywork control module to drive the corresponding bodywork electrical loads. The bodywork control module drives specific bodywork electrical loads such as water pumps, fans, motors, etc. according to the instructions of the cockpit domain controller to perform the physical actions required for the bodywork operation.

[0049] The rain / light sensor and light switch respectively input environmental signals and a light auto position signal to the body domain controller. The cockpit domain controller inputs the current bodywork operation mode and type to the body domain controller. The body domain controller integrates the environmental signals, the light auto position signal, and the current bodywork operation mode and type, and after processing through a control logic algorithm, activates the sweeper lights, and the bodywork control module drives the bodywork load to operate. In this embodiment, the control logic algorithm is as follows: the body domain controller activates the left and / or right sweeper lights only when the light switch is in the automatic headlight position, the rain / light sensor outputs a light on request signal, the bodywork operation mode is wash / sweep mode or road sweeping mode, and the bodywork operation status is in operation.

[0050] Preferably, the cockpit domain controller is connected to the body controller and the bodywork execution module via CAN bus. The light switch is connected to the body controller via hard wire. The rain light sensor is connected to the body domain controller via LIN bus.

[0051] Furthermore, the method for the vehicle body domain controller to judge and output the sweeping lighting control instruction is specifically as follows:

[0052] Assuming that the left and right sweeping brush lights are turned off in the initial state, when the body domain controller collects that the light gear is AUTO, the light and rain sensor light on request signal is to turn on the light, and at the same time receives the cabin domain control that the working mode of the upper body is washing and sweeping mode or road sweeping mode, the upper body operation type is left and / or right side and the upper body working status is working, the body domain controller will drive the left and / or right sweeping brush lights to light up after comprehensive judgment.

[0053] After the sweep brush light is on, if the corresponding enabling conditions are not met or it is manually turned off through the HMI, the body domain controller stops driving the corresponding sweep brush light and the sweep brush light goes out.

[0054] Example 2:

[0055] Combined with attachment Figure 3 As shown, a method for controlling automatic lighting of a sanitation vehicle sweeping plate includes the following specific steps:

[0056] S100, check whether the light switch is in the AUTO position, that is, whether it is set to the automatic headlight position;

[0057] If not satisfied, the process is terminated and the light is not turned on;

[0058] If it is satisfied, a close linkage mechanism is established with the rain and light sensor and the next step is entered;

[0059] S200, determining, by means of a rain light sensor, whether a light screen quantity signal reaches a light-on threshold, that is, whether the ambient light and weather conditions meet the light-on condition;

[0060] The light and rain sensor sends a request to turn on the lights based on the ambient light and weather conditions, such as dimming light at dusk, low illumination at night, and obstructed vision in rainy and foggy days. This signal serves as the basis for subsequent scanning lighting judgment and startup, realizing the automation of basic lighting and environmental adaptation.

[0061] If not satisfied, the process is terminated and the light is not turned on;

[0062] If satisfied, proceed to the next step;

[0063] S300, determining whether the upper loading operation mode is a washing and sweeping mode or a road sweeping mode;

[0064] If not satisfied, the process is terminated and the light is not turned on;

[0065] If satisfied, proceed to the next step;

[0066] S400, determining whether the loading operation type is a left-side operation or / and a right-side operation;

[0067] If not satisfied, the process is terminated and the light is not turned on;

[0068] If satisfied, go to the next step;

[0069] S500, judge whether the upper working state is in working;

[0070] If not satisfied, the process is terminated, and the lighting lamp is not turned on;

[0071] If satisfied, go to the next step;

[0072] In this embodiment, the cabin domain controller feeds back the related state to the body domain controller according to the upper working mode and working type.

[0073] S600, according to the upper working type, turn on the corresponding sweeping lighting lamp;

[0074] When all conditions are satisfied, send instructions to the body domain controller, and turn on the sweeping lighting lamp.

[0075] In this embodiment, the body domain controller comprehensively judges whether to automatically turn on the light illumination according to the light switch gear, light rain light sensor signal. If turned on, output the automatic headlight illumination state signal. At the same time, combined with the upper working mode and working type data transmitted by the cabin domain controller, output the control sweeping lighting circuit, realize stable, efficient and intelligent illumination control. The upper working mode and working type determine the illumination demand. When the upper control module working mode is in the washing and sweeping operation mode, continue to subdivide the working type: if it is left sweeping, automatically turn on the left sweeping lighting lamp; if it is right sweeping, turn on the right sweeping lighting lamp; if it is full sweeping, turn on the two sweeping lighting lamps. When the working is paused, switched to non-sweeping operation or parked, automatically turn off the corresponding sweeping lighting lamp according to the working condition change, and the whole process is free from manual intervention.

[0076] The present application solves the technical problems of the prior art that relies on manual opening of the sweeping lighting lamp, which disperses the driver's attention and affects the safety of the operation. The independent cab and upper function are integrated to utilize the cab automatic headlight and other configurations to realize the deep linkage of the operation scene. The present application solves the technical problems of the existing automatic lighting that does not combine the operation mode, operation type (left sweeping / right sweeping / full sweeping) precise control of the lamp group, and cannot adapt to diversified operation requirements. The present application integrates the cab automatic headlight function and the upper working condition, realizes the automatic opening / closing of the sweeping lighting lamp, reduces the operation complexity, improves the operation safety and efficiency, and at the same time, excavates the technical value of the integration of the cab and the upper function.

[0077] Although the present invention is described herein with reference to illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
