At the same time, a prohibition operation logic is set to select operation and prohibition according to weather conditions, which brings greater convenience to the driver, increases the vehicle's mileage, and improves the overall vehicle operation efficiency.

[0004] At present, there are two main types of step heaters, water heating and electric heating. Water heating requires the layout of water channels, with the help of the vehicle heating system. Electric heating steps have simple layout, only high-voltage power lines and low-voltage control lines need to be laid out. In the increasingly complex vehicle electronic control system, the application prospects are broad.

[0005] However, the existing control method increases the energy consumption of the entire vehicle, the driver cannot participate in the control, and the driver's subjective experience is reduced. Utility Model Content

[0006] The technical problem to be solved by the utility model is: how to solve the driver's control pain point and avoid the situation where the driver cannot turn off the air conditioner even if he wants to. Therefore, an integrated electric step heating automatic air conditioning electronic control system is provided.

[0007] To achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0008] An integrated electric step heating automatic air conditioning electronic control system is characterized by: including a step switch and a vehicle controller, wherein the step switch is connected to the air conditioning electronic control box through a low-voltage control line, the air conditioning electronic control box is also connected to the air conditioning electronic control box through a low-voltage control line, and the step switch is also connected to the air conditioning electronic control box through a high-voltage power supply line; the vehicle controller is connected to the air conditioning panel through a CAN communication line, and the air conditioning panel is also connected to the air conditioning electronic control box through a CAN communication line; the air conditioning electronic control box is connected to the vehicle's five-in-one controller through a high-voltage wiring harness.

[0009] The step switch is connected to a time relay, and the time relay is connected to the air conditioner electric control box.

[0010] The step switch is arranged in the vehicle step structure, and a temperature sensor is also arranged in the vehicle step structure; and the step switch is connected to the high-voltage contactor.

[0011] Compared with the existing technology, this utility model has the following advantages: the utility model is equipped with a step-inhibit operation logic, the user can prohibit the step-in operation, the step is associated with the door opening signal by default, and the door is closed after a set delay. The utility model is customer-oriented, bringing more convenience to customers and creating greater value for customers. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic diagram of the utility model. DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0014] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0015] like Figure 1 As shown, an integrated electric step heating automatic air conditioning electronic control system includes a step switch and a vehicle controller, wherein the step switch is connected to the air conditioning electronic control box through a low-voltage control line, the air conditioning electronic control box is also connected to the air conditioning electronic control box through a low-voltage control line, and the step switch is also connected to the air conditioning electronic control box through a high-voltage power supply line; the vehicle controller is connected to the air conditioning panel through a CAN communication line, and the air conditioning panel is also connected to the air conditioning electronic control box through a CAN communication line; the air conditioning electronic control box is connected to the vehicle five-in-one controller through a high-voltage wiring harness.

[0016] It should be noted that the above-mentioned five-in-one controller and vehicle controller are both existing technologies.

[0017] Furthermore, the step switch is connected to a time relay, which is in turn connected to the air conditioner's electronic control box. Users can set the step operation time to activate the step operation. When the step operation is not needed, the user can operate the air conditioner's electronic control box through the air conditioner panel to turn off the step operation. This allows the step operation time to be configurable, thereby reducing step power consumption and improving vehicle operating efficiency.

[0018] Furthermore, a step switch is installed in the vehicle's step structure, which also includes a temperature sensor. The step switch is connected to a high-voltage contactor. When the outdoor temperature sensed by the temperature sensor is below a certain set point in the air conditioning heating mode, step operation is enabled. When the temperature sensed by the temperature sensor exceeds a certain set point, a high-temperature alarm is triggered, and the step switch automatically triggers the high-voltage contactor, disconnecting it and protecting the vehicle's electrical system. Furthermore, the user can select whether to enable step operation through the air conditioning panel based on weather conditions, thereby increasing the vehicle's mileage.

[0019] The working principle of this utility model is:

[0020] The step switch signal can be transmitted to the air conditioning control box, and the low-voltage control and high-voltage power-on of the electric step can be controlled by operating the air conditioning panel and the air conditioning electronic control box.

[0021] In addition, the step in the present invention is not associated with the wall-mounted signal, and the operation and shutdown are selected according to the door state and the step-prohibited operation state, which is associated with the air-conditioning operation mode.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
