Description

Verification Simulator for Vehicle HVAC Systems The contents disclosed in this specification relate to a vehicle air conditioning system and a method for verifying the operation thereof. Unless otherwise indicated in this specification, the contents described in this section are not prior art for the claims of this application, and are not to be recognized as prior art simply because they are included in this section. Generally, an automotive HVAC system is a system that encompasses heating, ventilation, and air conditioning for a vehicle. To quickly create a comfortable interior environment, it utilizes the natural tendency of heat to move from high to low temperatures to artificially generate heat flow, thereby cooling the air below the ambient temperature. Recently, due to environmental and social regulations, the production of internal combustion engine vehicles is being discontinued, and the demand for eco-friendly electric vehicles is increasing. HVAC is an essential component for electric vehicles, and as the system operates on battery power, efficient thermal management and air conditioning systems are required to improve fuel efficiency and save energy. In the case of internal combustion engine vehicles, the energy source for HVAC utilizes engine waste heat; however, since electric vehicles cannot use engine waste heat or mechanical compressors, they use PTC heaters or recover heat via heat pumps to utilize for air conditioning and thermal management. Meanwhile, existing HVAC verification methods only have functions such as displaying the HVAC output signal and forcibly inputting sensor values using a variable resistor. Therefore, an accurate verification mechanism is required during the design phase prior to mass production to ensure the reliability of the control logic. In such cases, it is necessary to enter verification values using an auto-simulation function when creating the test list. The prior art with this background is to the extent of the following. FIG. 1 is a conceptual diagram of a verification simulator for a vehicle air conditioning system according to an embodiment. FIG. 2 is a configuration diagram of a simulator according to an embodiment. FIGS. 3 to 6 are drawings illustrating an integrated automotive HVAC pin map and a verification simulation pin map applied to a simulator according to an embodiment. FIG. 7 is a drawing showing a verification block applied to a simulator according to an embodiment. FIGS. 8 to 13 are flowcharts illustrating the operation of a simulator according to an embodiment. FIG. 1 is a diagram conceptually illustrating a verification simulator of a vehicle air conditioning system according to an embodiment. As illustrated in FIG. 1, the verification simulator (100) of a vehicle air conditioning system according to the embodiment is first connected to a manager terminal (120) and a vehicle air conditioning system (300). For example, the manager terminal (120) is connected to a PC via RS232 and connected to a vehicle HVAC (300). The verification simulator (100) of the vehicle air conditioning system creates a verification simulation pin map of the vehicle HVAC based on the existing integrated pin map of the vehicle HVAC, and through this, verifies the algorithm, for example, logic, and hardware operation of the vehicle HVAC. Specific verification also utilizes a specific verification block according to the embodiment. The verification block is linked with the verification simulation pin map of the vehicle HVAC and has a 1:1 customized verification method for each. For example, the verification simulation pin map of the vehicle HVAC is divided by actuator, blower, and signal, and each has a 1:1 customized verification method. The integrated pin map of the vehicle HVAC is divided into the front panel of the vehicle and the rear panel of the vehicle, and is created in various ways to match the connectors provided for each panel. For example, in the case of the rear panel, there are A, B, C, and D (REAL ROAD) connector types, and a pin map is created for each type. Specific details are explained through FIGS. 8 and 9. This is the same for the blower and the signal. The verification simulation pin map of the above-mentioned automotive HVAC is broadly divided into actuators, blowers, and signals of the automotive HVAC, and a verification simulation pin map is created for each. Thus, the automotive HVAC is verified in detail for each actuator, blower, and signal. Meanwhile, the verification block of the above-mentioned automotive HVAC is linked with the verification simulation pin map of the automotive HVAC and has a verification method based on a 1:1 customized approach for each. For example, the verification simulation pin map of the above-mentioned automotive HVAC is divided into actuators, blowers, and signals, and each has a verification method based on a 1:1 customized approach. The above administrator terminal (200) requests verification of the vehicle HVAC
