Description

Technical Field

[0001] The present application relates to the field of tire temperature control, and more particularly to a method and device for intelligently controlling tire cooling. Background Art

[0002] Car tires tend to heat up during long-distance driving or continuous downhill driving, especially in high-temperature summer environments. This problem not only aggravates the damage to the tires, but also significantly increases safety risks, such as the occurrence of tire blowouts.

[0003] The tire cooling systems of most cars on the market today rely on manual operation by the driver, which means the driver needs to actively intervene to start or shut down the cooling system.

[0004] The driver needs to perform a series of complex steps, including parking, getting off the car to check the tire temperature, and deciding whether to start or shut down the cooling system based on judgment. This is not only time-consuming and labor-intensive, but also increases the inconvenience during driving. Whether the tire temperature reaches the threshold that requires cooling often depends on the driver's experience and judgment. This subjectivity may lead to inaccurate judgment, thus affecting the cooling effect or safety. The manual operation mode may cause the driver to be distracted at critical moments, increasing the risk of traffic accidents. At the same time, if the high temperature of the tire is not detected and handled in time, it may cause serious consequences such as tire blowout. Summary of the invention

[0005] The purpose of the present application is to overcome the above-mentioned prior art and provide a method and device for intelligently controlling tire cooling.

[0042] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0043] This technical solution aims to solve the potential safety hazards caused by the increase in temperature of automobile tires during long-distance driving or extreme working conditions, especially the risk of tire blowout. By real-time monitoring of tire temperature and intelligent control of the cooling system, the tire temperature is maintained within a safe range, while providing an abnormal alarm mechanism to improve driving safety.

[0044] Please refer to Figure 1 to Figure 4 As shown, the present application provides a method for intelligently controlling tire cooling, comprising:

[0045] S101, detecting tire temperature in real time, and reporting the tire temperature to the BCM.

[0046] The temperature sensor is installed inside the tire or close to the tire surface to ensure that the actual temperature of the tire can be accurately measured. The selection of the position takes into account the characteristics of the temperature distribution of the tire during operation to ensure the accuracy and representativeness of the measurement results.

[0047] According to the application requirements, select a suitable temperature sensor type, such as a thermistor, a thermocouple or an integrated temperature sensor, etc. The sensor can convert the temperature of the tire into an electrical signal.

[0048] The temperature sensor transmits temperature data to the control system inside the vehicle wirelessly or wired. In the wired mode, the sensor is connected to the BCM through the vehicle's internal communication network (such as CAN bus); in the wireless mode, wireless radio frequency technology (such as Bluetooth, Zigbee, etc.) is used for data transmission.

[0049] When the tire temperature changes, the temperature sensor captures this change in real time and converts it into an electrical signal, which is then received and recorded by the control system inside the vehicle.

[0050] The control system processes the received temperature data, including filtering, amplification, analog-to-digital conversion and other steps to ensure the accuracy and reliability of the data. At the same time, the system compares and analyzes the temperature data of multiple tires to identify any abnormalities or imbalances.

[0051] In the above, CAN (Controller Area Network) is a widely used communication protocol in vehicles, which is used to connect various electronic control units (ECUs) in vehicles and exchange data. CAN signals refer to data packets transmitted according to the CAN protocol standard. These data packets contain information that the sender needs to pass to the receiver.

[0052] In this embodiment, the tire temperature data is not transmitted all at once, but is continuously sent to the BCM at certain time intervals (i.e., cycles). This periodic transmission method ensures that the BCM can obtain the latest tire temperature data in real time. Each data packet is transmitted according to the CAN protocol standard. These data packets are transmitted independently in the vehicle's internal network, but can be designed to contain multiple types of information.

[0053] In order to improve data transmission efficiency and reduce network load, data packaging is adopted. That is, the temperature data of multiple tires (for example, the temperature data of 4 tires of an ordinary car) are integrated into one CAN signal for transmission. In this way, when the BCM receives a CAN signal, it can obtain the temperature data of multiple tires at the same time without waiting for multiple separate signals.

[0054] S102: If the tire temperature is higher than a preset threshold Threshold1, the BCM automatically starts a tire cooling module to spray water on the tire to cool it down.

[0055] The BCM (body control module) performs a series of logical judgments according to the received tire temperature data and the start / stop status of the current tire cooling module to determine whether to start or stop the water spraying function of the tire cooling module.

[0056] The BCM has built-in preset temperature thresholds Threshold 1 and Threshold 2. When the BCM detects that the temperature of a tire is higher than Threshold 1, it automatically determines that the temperature is too high and needs to start the cooling system.

[0057] Then, the BCM will send a command to the tire cooling system to start the water spray device. The water spray device quickly sprays water to cool the high-temperature tires, and the evaporation of water takes away the heat from the tire surface, thereby reducing the tire temperature.

[0058] S103 . During the cooling process, if the tire temperature is lower than a threshold value Threshold 2 which is lower than Threshold 1 , the BCM automatically turns off the tire cooling module.

[0059] When the tire temperature drops below Threshold 2, the BCM again determines that the tire has returned to a safe temperature range based on the detected temperature data, and then sends a command to shut down the water spray cooling system to save water resources and electricity.

[0060] S104: If the temperature of any one or more tires of the vehicle is higher than a threshold value Threshold3 which is greater than Threshold1, the BCM will send an alarm to the instrument display module to prompt the driver to pay attention.

[0061] In addition to conventional temperature monitoring and cooling control, an abnormal alarm function is also set up to deal with special situations that may arise.

[0062] When the BCM detects that the temperature of a tire suddenly rises sharply and exceeds the preset higher threshold Threshold 3 (this usually means that the cooling system may have a fault, such as a blockage in the water spray device, insufficient water supply or circuit failure, etc.), the BCM will immediately send an alarm signal to the instrument display system.

[0063] After receiving the warning signal, the instrument display system will notify the driver of the abnormal tire temperature in a conspicuous manner (such as a flashing icon, alarm sound or text prompt) on the instrument panel.

[0064] According to the prompts on the dashboard, the driver should immediately find a suitable place to stop the car, get off to check the condition of the vehicle's tires, and try to take other measures (such as using external coolant, waiting for the tires to cool naturally, etc.) to cool the tires to avoid dangerous situations such as tire blowouts caused by excessive tire temperature.

[0065] Furthermore, the described BCM determines whether to start or stop the water spray cooling process according to the tire temperature and the start / stop status of the current tire cooling module, and the detailed steps include:

[0066] Step 1: Determine whether the tire cooling module is on or off.

[0067] The BCM first queries the start / stop status of the current tire cooling module by reading the control circuit status of the cooling module or receiving the status signal from the cooling module.

[0068] Step 2: If the tire cooling module is turned off.

[0069] If the cooling module is currently in the off state, the BCM will traverse the temperature data of all tires. For each tire temperature, it will first compare it with the preset Threshold1.

[0070] If the temperature of all tires is not higher than Threshold1, it is further checked whether it is higher than Threshol d2.

[0071] If the temperature of any tire is higher than Threshold1, the tire temperature information higher than Threshold1 will be immediately sent to BCM, and the tire cooling module will be started to spray water for cooling.

[0072] Further determine whether it is higher than Threshold 2 (lower than the threshold of Threshold 1).

[0073] If the temperature of any tire is higher than Threshold 2, the tire cooling module is kept activated to spray water for cooling.

[0074] If the temperature of all tires is not higher than Threshold2, no action is taken and the process ends.

[0075] Step 3: If the tire cooling module is turned on.

[0076] If the temperature of all tires is lower than Threshold 1, it means that the temperature of the tires is low enough and no further cooling is required. Therefore, the BCM will send a command to the tire cooling module to turn off the water spray function to save energy and avoid unnecessary mechanical wear.

[0077] If the temperature of any tire is not lower than Threshold 1, it means that the temperature of at least one tire is still high and may need to be cooled down. However, under the current logic, as long as the temperature of one tire is not lower than Threshold 1, the BCM will not actively shut down the cooling module.

[0078] Furthermore, Threshold 3 (which is a higher threshold than Threshold 1) is also provided. When the tire temperature is higher than Threshold 3, the instrument display system is notified of the abnormal tire temperature through the CAN line.

[0079] The present application also provides a device for intelligently controlling tire cooling, comprising: a tire temperature detection module, a BCM and a tire cooling module;

[0080] The tire temperature detection module is used to detect the tire temperature in real time and report the tire temperature to the BCM;

[0081] The BMC is used to automatically start the tire cooling module to spray water on the tire to cool it down if the tire temperature is higher than a preset threshold Threshold 1; during the cooling process, if the tire temperature is lower than another threshold Threshold 2 which is less than Threshold 1, the BCM automatically turns off the tire cooling module; if the temperature of any one or more tires of the car is higher than another threshold Threshold 3 which is greater than Threshold 1, the BCM will send an alarm to the instrument display module to prompt the driver to pay attention.

[0082] Furthermore, the tire temperature detection module reports the tire temperature to the BCM, including:

[0083] Periodically reporting the tire temperature to the BCM via a CAN signal;

[0084] Each of the CAN signals includes the tire temperatures of multiple tires.

[0085] Furthermore, if the tire temperature is higher than a preset threshold Threshold1, the BCM automatically starts the tire cooling module to spray water to cool the tire, including:

[0086] The BCM determines whether to start or stop the tire cooling module from spraying water according to the tire temperature and the current start / stop status of the tire cooling module.

[0087] Further, the BCM determines whether to start or stop the tire cooling module to spray water according to the tire temperature and the current start / stop state of the tire cooling module, the steps comprising:

[0088] Determining whether the tire cooling module is on or off;

[0089] If the tire cooling module is turned off, then the tire temperatures of multiple tires are checked to see if they are higher than Threshold 1. If they are higher than Threshold 1, multiple tire temperatures are sent, the tire cooling module is turned on, and it is further determined whether they are higher than Threshold 2. If they are higher than Threshold 2, the tire cooling module is kept turned on; if they are not higher than Threshold 2, the process ends;

[0090] If the tire cooling module is turned on, the tire temperatures of multiple tires are checked to see if they are lower than Threshold 1. If they are lower than Threshold 1, the tire cooling module is turned off and the process ends; if they are not lower than Threshold 1, the process ends.

[0091] Furthermore, it also includes an instrument display module:

[0092] The instrument display module is used to remind the driver that the tire temperature is abnormal and the vehicle should be stopped when the tire cooling module is abnormal or there is no water in the water spraying device and the tire temperature of the car is higher than Threshold 3.
