Abstract

The present invention relates to an automatic ventilation control system and a control method for a vehicle. The system includes a mode button, a rain sensor and/or wiper detection module, a vehicle speed sensor, an air conditioning control system, and an automatic ventilation controller. The automatic ventilation controller determines whether the automatic ventilation mode is turned on according to an operation received by the mode button; determines whether it is raining outside the vehicle through the rain sensor and/or wiper detection module; determines whether the vehicle speed is within a preset range according to the vehicle speed detected by the vehicle speed sensor; determines whether the vehicle interior temperature is close to a preset temperature according to the vehicle interior temperature detected by the air conditioning control system and the received preset temperature; and when it is determined that the automatic ventilation mode is turned on, it is not raining outside the vehicle, the vehicle speed is within a preset range, and the vehicle interior temperature is close to a preset temperature, the vehicle is controlled to perform ventilation.

Description

Automatic ventilation control system and control method for vehicle The present invention relates to the control of a vehicle, and in particular to an automatic ventilation control system and a control method for a vehicle. As vehicle technology continues to advance, consumers are demanding performance improvements across various aspects of vehicles. Maintaining good air quality inside the vehicle is also one of these consumer requirements for comfort. The air quality inside the vehicle is an intuitive experience for passengers and can affect their mood. Conventional vehicle ventilation systems have primarily been implemented through the manual operation of air conditioners, sunroofs, and windows. However, manual operation by the driver causes operational inconvenience and even increases driving hazards. Therefore, there is an urgent need for an automatic vehicle ventilation control system and control method. The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs. Hereinafter, exemplary embodiments of the present invention will be described in more detail by combining the drawings. For clarity, the same components in different drawings are indicated by the same reference numerals. It should be noted that the drawings are illustrative only and are not necessarily drawn in proportion. FIG. 1 is a block diagram of an automatic ventilation control system for a vehicle according to an embodiment of the present invention. FIGS. 2a to 2d are flowcharts of the operation of an automatic ventilation controller according to an embodiment of the present invention. FIG. 3 is a flowchart of a control method for automatic vehicle ventilation according to an embodiment of the present invention. Hereinafter, embodiments of the present invention are described in detail. These embodiments are implemented based on the technical method of the present invention, and detailed implementation methods and specific operation processes are disclosed; however, the scope of protection of the present invention is not limited to the following embodiments. FIG. 1 is a block diagram of an automatic ventilation control system for a vehicle according to an embodiment of the present invention. As shown in FIG. 1, the automatic ventilation control system for a vehicle according to an embodiment of the present invention includes a mode button (11), at least one of a rain sensor (12) and a wiper detection module (13), a vehicle speed sensor (14), an air conditioning control system (15), an automatic ventilation controller (16), a sunroof controller (17), an air conditioning unit (Air Conditioner, AC, 18), and a sunroof (19). As illustrated in FIG. 1, the mode button (11) and the automatic ventilation controller (16) can communicate. The mode button (11) is configured to receive user operations to turn the automatic ventilation mode on or off. Specifically, the mode button (11) may be an on/off button, a select button, a physical button (e.g., a button for executing various functions), a jog dial, and/or a touchpad. When a user presses the mode button (11), the mode button (11) can receive the user's press and generate a signal to turn the automatic ventilation mode on or off. The automatic ventilation controller (16) is configured to determine whether the automatic ventilation mode is turned on based on the operation received by the mode button (11). Specifically, the mode button (11) can send a signal to turn the automatic ventilation mode on or off to the automatic ventilation controller (16), and the automatic ventilation controller (16) can determine whether the automatic ventilation mode is turned on based on the received signal. Determining that the automatic ventilation mode is turned on by the automatic ventilation controller (16) is one of the preconditions for the vehicle to perform ventilation. In one embodiment, the rain sensor (12) and the automatic ventilation controller (16) can communicate with each other. The rain sensor (12) is configured to detect rainfall outside the vehicle. Specifically, the rain sensor (12) can be mounted on the rearview mirror base inside the vehicle and emit infrared rays toward the front windshield glass, and detect rainfall outside the vehicle by receiving reflected infrared rays to detect whether it is raining on the front windshield glass. Generally, the more rainwater there is on the front windshield glass, the less far-infrared rays are reflected. The automatic ventilation controller (16) is configured to determine whether it is raining outside the vehicle based on the rainfall outside the vehicle detected by the rain sensor (12). Specifically, the rain sensor (12) can send the detected rainfall outside the vehicle information to the automatic ventilation controller (16), and the automatic ventilation co
