Description

Technical Field

[0001] This invention belongs to the field of automotive tire technology, and more specifically, relates to an automotive tire blowout prevention device. This invention also relates to a method for preventing automotive tire blowouts. Background Technology

[0002] Current technology collects tire pressure and temperature information and directly compares it with preset values ​​to determine whether to initiate emergency braking. Emergency braking is initiated if the tire pressure and temperature are higher than the preset value or the tire pressure is lower than the preset value. However, actual vehicle conditions are more complex. For example, if the tire pressure is too low, it will not exceed the preset value, and even if there is a risk of tire blowout, no warning will be given, leading to judgment errors. During high-speed driving, the tire sidewalls repeatedly bend and compress during high-speed rotation, generating a large amount of frictional heat. The tire pressure and temperature rise rapidly, lowering the temperature threshold for a blowout. The tire pressure will rise with the temperature, but will stabilize after a rapid increase and will not exceed the tire pressure threshold. Current technology, by only comparing tire pressure and temperature values, cannot accurately prevent tire blowouts; for aging tires, the temperature and tire pressure thresholds for a blowout will also decrease.

[0003] Existing technology includes a "Car Tire Blowout Safety and Stability Control System" with publication number "108715163A". This technology relates to a "Car Tire Blowout Safety and Stability Control System" for manned and unmanned vehicles, based on the vehicle's braking, drive, steering, and suspension systems, and belongs to the field of car tire blowout safety. This system establishes tire pressure detection, state tire pressure, and steering mechanics state mode for tire blowout determination. It adopts a car tire blowout safety and stability control mode, model and algorithm, control structure and process. Based on the blowout state point, it coordinates vehicle braking, drive, steering, steering wheel rotation force, and suspension balance control through blowout control entry and exit, and normal and blowout control mode switching, achieving blowout control in cases of overlapping real or non-real blowout processes. Under conditions of rapid changes in the blowout process state, the blown wheel, and the vehicle's motion state, it overcomes important technical barriers such as severe instability of the wheel and vehicle during a blowout and the difficulty in controlling extreme blowout states, thus addressing this long-standing major issue of car tire blowout safety. However, this technology does not address the technical problems and solutions of this application. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a car tire blowout prevention device that, in view of the shortcomings of the prior art, can determine whether there is a risk of tire blowout based on whether the tire pressure or tire temperature is rising during vehicle operation, and can provide timely warnings and intervention when there is a risk of tire blowout, thereby reducing vehicle driving safety and ensuring the safety of personnel.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This invention relates to a tire blowout prevention device for automobiles. When the vehicle uses a direct tire pressure monitoring system, tire pressure sensors and tire temperature sensors are installed on the wheels. The tire pressure sensors and tire temperature sensors are respectively connected to the vehicle ECU. The vehicle ECU is respectively connected to the vehicle power module and the vehicle brake control module. The vehicle ECU is also connected to an in-vehicle acoustic alarm and an external optical alarm. The vehicle ECU stores the preset tire pressure rise range value (bar) and the preset tire temperature rise range value (C1). The vehicle ECU also stores the preset high tire pressure value (bar2) and the preset high tire temperature value (C2).

[0006] When the vehicle uses indirect tire pressure monitoring, the tire pressure is monitored by the tire pressure calculation program module of the vehicle braking control module to obtain the real-time tire pressure value bar3.

[0007] The tire pressure sensor is configured to provide real-time feedback of the tire pressure value bar3 to the vehicle ECU; the tire temperature sensor is configured to provide real-time feedback of the tire temperature value C3 to the vehicle ECU.

[0008] The in-vehicle acoustic alarm uses a buzzer.

[0009] The aforementioned external optical alarm device uses the vehicle's hazard lights.

[0010] This invention also provides a simple method for preventing tire blowouts in automobiles. This method assesses the risk of a blowout based on an upward trend in tire pressure or temperature during vehicle operation, and provides timely warnings and interventions when a blowout risk is present. This reduces the risk of vehicle damage and ensures the safety of occupants. The method employs pressure monitoring for blowout prevention, specifically targeting direct tire pressure. The steps of this blowout prevention method are as follows: S1. The vehicle ECU stores the preset tire pressure rise range value bar1 and the preset tire pressure high value bar2; S2. When the vehicle is in direct tire pressure mode, the tire pressure sensors on the wheels acquire the real-time tire pressure value bar3 and feed it back to the vehicle ECU in real time. S3. During vehicle operation, the vehicle ECU obtains the real-time tire pressure data bar3 and compares it with the stored preset tire pressure rise range value bar1. When the real-time tire pressure data bar3 rises rapidly, and the actual rise pressure value bar4 exceeds the preset rise pressure range value bar1 within the set time period t1, and the real-time tire pressure value bar3 exceeds the preset high tire pressure value bar2, the vehicle ECU determines that there is a risk of tire blowout. S4. The vehicle ECU controls and executes the emergency braking command: it outputs a signal to the vehicle power module to start limiting torque output; it outputs a signal to the vehicle braking control module to start wheel-end braking; at the same time, it activates the in-vehicle acoustic alarm and the external optical alarm. The in-vehicle acoustic alarm reminds the occupants to pay attention to the vehicle status, and the external optical alarm reminds the people and vehicles outside the vehicle to take evasive action. S5. As the vehicle speed decreases or slows down to a stop, the tire pressure decreases accordingly until the real-time tire pressure data bar3 is lower than the preset high tire pressure value bar2, and the real-time tire pressure data bar3 shows no upward trend. Once the risk is deemed resolved, the emergency braking command is stopped.

[0011] This invention also provides a simple method for preventing tire blowouts in automobiles. This method assesses the risk of a blowout based on an upward trend in tire pressure or temperature during vehicle operation, and provides timely warnings and intervention when a blowout risk is present, thereby reducing vehicle safety and ensuring passenger safety. This method addresses indirect tire pressure monitoring, and the preventative steps of the method are as follows: S1. The vehicle ECU4 stores the preset tire pressure rise range value bar1 and the preset tire pressure high value bar2; S2. When the vehicle uses indirect tire pressure, the tire pressure is monitored by the tire pressure calculation program module of the vehicle braking control module to obtain real-time tire pressure data bar3. S3. During vehicle operation, the vehicle ECU4 acquires the real-time tire pressure data bar3 and compares it with the stored preset tire pressure rise range value bar1. When the real-time tire pressure data bar3 rises rapidly, and the actual rise pressure value bar4 exceeds the preset rise pressure range value bar1 within the set time period t1, and the real-time tire pressure value bar3 exceeds the preset high tire pressure value bar2, the vehicle ECU determines that there is a risk of tire blowout. S4. The vehicle ECU4 controls and executes the emergency braking command: outputs a signal to the vehicle power module 5 to start limiting torque output; outputs a signal to the vehicle brake control module to start wheel-end braking; and simultaneously activates the in-vehicle acoustic alarm and the external optical alarm. The in-vehicle acoustic alarm 7 reminds the occupants to pay attention to the vehicle status, and the external optical alarm reminds the occupants and vehicles outside the vehicle to take evasive action. S5. As the vehicle speed decreases or slows down to a stop, the tire pressure decreases accordingly until the real-time tire pressure data bar3 is lower than the preset high tire pressure value bar2, and the real-time tire pressure data bar3 shows no upward trend. Once the risk is deemed resolved, the emergency braking command is stopped.

[0012] During vehicle operation, if the real-time tire pressure data bar3 rises rapidly, and the tire pressure rises by more than 0.2-0.4 bar within 5-10 minutes (a time period t1 is 5-10 minutes), exceeding the preset pressure range bar1 and showing a continuous upward trend, the vehicle ECU4 determines that there is a risk of tire blowout and controls the execution of an emergency braking command.

[0013] This invention also provides a simple method for preventing tire blowouts in automobiles. This method involves assessing the risk of a blowout based on an upward trend in tire pressure or temperature during vehicle operation, and providing timely warnings and intervention when a blowout risk is present. This reduces the risk of vehicle damage and ensures the safety of occupants. The method employs temperature monitoring for tire blowout prevention. The steps of the method are as follows: S1. The vehicle ECU4 stores the preset tire temperature rise range value C1 and the preset high tire temperature value C2. S2. When the vehicle uses direct tire pressure, the tire temperature sensor on the wheel obtains the real-time tire temperature value C3 and feeds it back to the vehicle ECU in real time; when the vehicle uses indirect tire pressure, the tire pressure is monitored by the tire pressure calculation program module of the vehicle brake control module to obtain the real-time tire pressure value bar3. S3. During vehicle operation, the vehicle ECU obtains the real-time tire temperature value C3 and compares it with the stored preset tire temperature rise range value C1. When the real-time tire temperature value C3 rises rapidly, and the actual temperature rise value C4 exceeds the preset tire temperature rise range value C1 within the set time period t1, and the real-time tire temperature value C3 exceeds the preset high temperature value C2, the vehicle ECU4 determines that there is a risk of tire blowout. S4. The vehicle ECU controls and executes the emergency braking command: it outputs a signal to the vehicle power module to start limiting torque output; it outputs a signal to the vehicle braking control module to start wheel-end braking; at the same time, it activates the in-vehicle acoustic alarm and the external optical alarm. The in-vehicle acoustic alarm reminds the occupants to pay attention to the vehicle status, and the external optical alarm reminds the people and vehicles outside the vehicle to take evasive action. S5. As the vehicle speed decreases or slows down to a stop, the tire pressure decreases accordingly until the real-time tire temperature C3 is lower than the preset high tire temperature C2, and the real-time tire temperature C3 shows no upward trend. If the risk is deemed to be eliminated, the emergency braking command is stopped.

[0014] During vehicle operation, if the real-time tire temperature C rises rapidly within a set time period t1 of 5-10 minutes, and the tire temperature rises by more than 20℃-30℃ within 5-10 minutes, exceeding the preset temperature rise range value C1, and shows a continuous upward trend, the vehicle ECU determines that there is a risk of tire blowout and controls the execution of an emergency braking command.

[0015] The working principle and beneficial effects of the technical solution adopted in this invention are as follows: The tire blowout prevention device and method described in this invention address problems in existing technologies. A key issue with existing technologies is that when tire pressure is too low, the tire sidewall heats up abnormally during high-speed driving, but the tire pressure does not rise continuously and thus does not exceed a preset value, making accurate blowout prevention impossible. This invention determines the risk of a blowout by the rate of increase in tire temperature or tire pressure, providing more accurate identification. Using the rate of increase in tire temperature or tire pressure as the judgment benchmark is more accurate and timely than using the actual tire temperature and tire pressure values ​​as the benchmark for blowout monitoring. Whether for direct or indirect tire pressure monitoring, the device and method of this invention can reliably identify the risk of a blowout. For aging tires, the tire temperature and tire pressure thresholds for a blowout decrease. However, by comparing the rate of increase in tire temperature or tire pressure, this invention is not affected by the actual tire temperature and tire pressure values, ensuring accurate warnings of blowout risk for both new and old tires. When a vehicle is speeding, its temperature and tire pressure will rise abnormally. At this time, the rate of increase in tire temperature or tire pressure may exceed the calibrated / preset values. If the driver actively slows down when the tire temperature or tire pressure reaches the alarm value, and the tire temperature and tire pressure show no further upward trend, a judgment will be made that there is no risk of tire blowout, avoiding misjudgment. In existing technology, emergency braking is initiated whenever tire temperature or tire pressure rises. The device and method of this invention do not only control tire pressure and temperature, but also determine whether to issue a risk warning by comparing the rate of increase in temperature or tire pressure and whether there is a continuous upward trend, thus avoiding the aforementioned misjudgment.

[0017] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of the present invention, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1As shown in Embodiment 1, this invention is a tire blowout prevention device for automobiles. When the vehicle uses a direct tire pressure monitoring system, a tire pressure sensor 2 and a tire temperature sensor 3 are installed on wheel 1. The tire pressure sensor 2 and tire temperature sensor 3 are respectively connected to the vehicle ECU 4. The tire pressure sensor 2 and tire temperature sensor 3 can be installed separately, or they can be integrated sensors. The vehicle ECU 4 is connected to the vehicle power module 5 and the vehicle brake control module 6. The vehicle ECU 4 is also connected to an in-vehicle acoustic alarm 7 and an external optical alarm 8. An in-vehicle optical alarm can also be installed inside the vehicle, or the acoustic alarm device can also function as an optical alarm. The vehicle ECU 4 stores a preset tire pressure rise range value bar1 and a preset tire temperature rise range value C1; it also stores a preset high tire pressure value bar2 and a preset high tire temperature value C2. To address the shortcomings of the prior art, an improved technical solution is proposed. The structural design addresses problems in existing technologies. A key issue with existing technologies is that when tire pressure is too low, the tire sidewall heats up abnormally during high-speed driving, but the tire pressure doesn't rise continuously and never exceeds a preset value, making accurate blowout prevention impossible. This invention determines blowout risk by the rate of increase in tire temperature or tire pressure, providing more accurate identification. Using the rate of increase in tire temperature or tire pressure as the benchmark is more accurate and timely than using the actual tire temperature and pressure values ​​for blowout monitoring. Whether for direct or indirect tire pressure monitoring, the device and method of this invention can reliably identify blowout risk. For aging tires, the tire temperature and pressure thresholds for blowout detection decrease. This invention, by comparing the rate of increase in tire temperature or tire pressure, is unaffected by these numerical values, ensuring accurate blowout warnings for both new and old tires. When a vehicle is speeding, its temperature and tire pressure will rise abnormally. At this time, the rate of increase in tire temperature or tire pressure may exceed the calibrated / preset values. If the driver actively slows down when the tire temperature or tire pressure reaches the alarm value, and the tire temperature and tire pressure show no further upward trend, a judgment will be made that there is no risk of tire blowout, avoiding misjudgment. In existing technology, emergency braking is initiated whenever tire temperature or tire pressure rises. The device and method of this invention do not only control tire pressure and temperature, but also determine whether to issue a risk warning by comparing the rate of increase in temperature or tire pressure and whether there is a continuous upward trend. This avoids the aforementioned misjudgment, thus not only reliably predicting and monitoring the risk of tire blowout, but also effectively improving the accuracy of the judgment and reducing misjudgment.

[0018] As attached Figure 2As shown in Example 2, when the vehicle uses an indirect tire pressure monitoring system, the tire pressure is monitored by the tire pressure calculation module 9 of the vehicle brake control module 6 to obtain the real-time tire pressure value bar3. In the above structure, the real-time tire pressure value bar3 is obtained for vehicles that do not obtain pressure values ​​through tire pressure sensors. The tire pressure can be monitored by the tire pressure calculation module 9 of the vehicle brake control module 6, and the real-time tire pressure value bar3 can still be obtained. The tire pressure calculation program is prior art and not an improvement of this invention. This invention is a direct application of this prior art as a data acquisition step in its improvement.

[0019] The tire pressure sensor 2 is configured to provide real-time tire pressure (bar3) feedback to the vehicle ECU 4; the tire temperature sensor 3 is configured to provide real-time tire temperature (C3) feedback to the vehicle ECU 4. With this configuration, the tire blowout prevention device and method of this application requires the acquisition of multiple data points. The real-time tire pressure (bar3) is acquired by the tire pressure sensor 2 and fed back to the vehicle ECU 4 in real-time; the real-time tire temperature (C3) is acquired by the tire temperature sensor 3 and fed back to the vehicle ECU 4 in real-time, providing data support for preventing tire blowouts.

[0020] The in-vehicle acoustic alarm 7 is a buzzer. In this configuration, the buzzer is located inside the vehicle and can emit a buzzing sound to alert the driver when there is a risk of tire blowout.

[0021] The aforementioned external optical warning device 8 uses vehicle hazard lights. In the above structure, the external optical warning device 8 uses vehicle hazard lights; when there is a risk of tire blowout, the hazard lights flash to alert drivers of other vehicles nearby, thus reliably enabling vehicle avoidance.

[0022] This invention also includes a simple method, based on Embodiment 1, for preventing tire blowouts during vehicle operation. This method assesses the risk of a blowout based on an upward trend in tire pressure or temperature, and provides timely warnings and intervention when a blowout risk is present. This reduces the risk of vehicle damage and ensures the safety of occupants. The method employs pressure monitoring for blowout prevention, specifically targeting direct tire pressure. The preventative steps of this method are as follows: S1. The vehicle ECU4 stores the preset tire pressure rise range value bar1 and the preset high tire pressure value bar2. S2. When the vehicle uses a direct tire pressure monitoring system, the tire pressure sensor 2 on wheel 1 acquires the real-time tire pressure value bar3 and feeds it back to the vehicle ECU4 in real time. S3. During vehicle operation, after acquiring the real-time tire pressure data bar3, the vehicle ECU4 compares the real-time tire pressure data bar3 with the stored preset tire pressure rise range value bar1. If the real-time tire pressure data bar3 rises rapidly, and within a set time period t1, the actual rise pressure value bar4 exceeds the preset rise pressure range value bar1, and the real-time tire pressure value bar3 exceeds the tire pressure range... The vehicle's ECU4 determines there is a risk of tire blowout when the preset high tire pressure value is bar2. S4. The ECU4 executes an emergency braking command: it outputs a signal to the vehicle's power module 5 to limit torque output; it also outputs a signal to the vehicle's brake control module 6 to initiate wheel-end braking; simultaneously, it activates the in-vehicle acoustic alarm 7 and the external optical alarm 8. The in-vehicle acoustic alarm 7 alerts occupants to the vehicle's status, and the external optical alarm 8 alerts pedestrians and other vehicles to take evasive action. S5. As the vehicle speed decreases or comes to a stop, the tire pressure decreases until the real-time tire pressure data bar3 is below the preset high tire pressure value bar2, and the real-time tire pressure data bar3 shows no upward trend. At this point, the risk is considered eliminated, and the emergency braking command is stopped. This method is for direct tire pressure monitoring, calculating the rate of increase in tire pressure and using a continuous upward trend to determine whether a blowout warning should be issued, ensuring accurate prediction and avoiding misjudgments.

[0023] This invention also includes a simple method, based on Embodiment 2, for preventing tire blowouts during vehicle operation. This method assesses the risk of a blowout based on an upward trend in tire pressure or temperature, and provides timely warnings and intervention when a blowout risk is present. This reduces vehicle safety and ensures passenger safety. The method addresses indirect tire pressure monitoring, and the steps involved are as follows: S1. The vehicle ECU4 stores the preset tire pressure rise range value bar1 and the preset high tire pressure value bar2. S2. When the vehicle uses indirect tire pressure monitoring, the tire pressure is monitored by the tire pressure calculation program module 9 of the vehicle brake control module 6 to obtain the real-time tire pressure data bar3. S3. During vehicle operation, after the vehicle ECU4 obtains the real-time tire pressure data bar3, it compares the real-time tire pressure data bar3 with the stored preset tire pressure rise range value bar1. When the real-time tire pressure data bar3 rises rapidly, and within a set time period t1, the actual rise pressure value bar4 exceeds the preset rise pressure range value bar1, and the real-time tire pressure value bar3 exceeds the tire pressure range... The vehicle's ECU4 determines there is a risk of tire blowout when the preset high tire pressure value is set at bar2. S4. The ECU4 executes an emergency braking command: it outputs a signal to the vehicle's power module 5 to limit torque output; it also outputs a signal to the vehicle's brake control module 6 to initiate wheel-end braking; simultaneously, the in-vehicle acoustic alarm 7 and the external optical alarm 8 are activated. The in-vehicle acoustic alarm 7 alerts occupants to the vehicle's status, while the external optical alarm 8 alerts pedestrians and other vehicles to take evasive action. S5. As the vehicle speed decreases or comes to a stop, the tire pressure decreases until the real-time tire pressure data bar3 is below the preset high tire pressure value bar2, and the real-time tire pressure data bar3 shows no upward trend. At this point, the risk is considered eliminated, and the emergency braking command is stopped. This method is for indirect tire pressure monitoring, calculating the rate of increase in tire pressure and using a continuous upward trend to determine whether a blowout warning should be issued, ensuring accurate prediction and avoiding misjudgments.

[0024] Based on Example 1, during vehicle operation, if the real-time tire pressure data bar3 rises rapidly, and within a set time period t1 of 5-10 minutes, the tire pressure rises by more than 0.2-0.4 bar (exceeding the preset pressure range bar1) and shows a continuous upward trend, the vehicle ECU4 determines that there is a risk of tire blowout and executes an emergency braking command. The specific values ​​for the aforementioned events and pressures are set according to the actual vehicle conditions, such as tire performance, for different vehicle models. The values ​​above are only approximate and can be set specifically for each vehicle model.

[0025] This invention also includes a simple method, based on Embodiment 1, for preventing tire blowouts during vehicle operation. This method assesses the risk of a blowout based on an upward trend in tire pressure or temperature, and provides timely warnings and intervention when a blowout risk is present. This reduces the risk of vehicle damage and ensures the safety of occupants. The method employs temperature monitoring for blowout prevention, and the steps are as follows: S1. The vehicle ECU4 stores the preset tire temperature rise range value C1 and the preset high tire temperature value C2. S2. When the vehicle uses direct tire pressure, the tire temperature sensor 3 on wheel 1 acquires the real-time tire temperature value C3 and feeds it back to the vehicle ECU 4 in real time; when the vehicle uses indirect tire pressure, the tire pressure is monitored by the tire pressure calculation program module 9 of the vehicle brake control module 6 to acquire the real-time tire pressure value bar3. S3. During vehicle operation, the vehicle ECU4 obtains the real-time tire temperature value C3 and compares it with the stored preset tire temperature rise range value C1. When the real-time tire temperature value C3 rises rapidly, and the actual temperature rise value C4 exceeds the preset tire temperature rise range value C1 within the set time period t1, and the real-time tire temperature value C3 exceeds the preset high temperature value C2, the vehicle ECU4 determines that there is a risk of tire blowout. S4. The vehicle ECU4 controls and executes the emergency braking command: outputs a signal to the vehicle power module 5 to start limiting torque output; outputs a signal to the vehicle brake control module 6 to start wheel-end braking; and simultaneously activates the in-vehicle acoustic alarm 7 and the external optical alarm 8. The in-vehicle acoustic alarm 7 reminds the occupants to pay attention to the vehicle status, and the external optical alarm 8 reminds the occupants and vehicles outside the vehicle to take evasive action. S5. As the vehicle speed decreases or slows down to a stop, the tire pressure decreases accordingly until the real-time tire temperature C3 is lower than the preset high tire temperature C2, and the real-time tire temperature C3 shows no upward trend. If the risk is deemed to be eliminated, the emergency braking command is stopped.

[0026] During vehicle operation, if the real-time tire temperature C rises rapidly, exceeding the preset temperature rise range C1 by 20°C-30°C within a set time period t1 (5-10 minutes), and shows a continued upward trend, the vehicle's ECU4 determines there is a risk of tire blowout and executes an emergency braking command. Specific values ​​are set according to the tire performance and other real-world conditions of different vehicle models; this is just an example.

[0027] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner.

During vehicle operation, the vehicle ECU (4) obtains the real-time tire temperature value C3 and compares the real-time tire temperature value C3 with the stored tire temperature preset rise range value C1. When the real-time tire temperature value C3 rises rapidly, the actual temperature rise value C4 exceeds the tire temperature preset rise range value C1 within the set time period t1, and the real-time tire temperature value C3 exceeds the tire temperature preset high temperature value C2, the vehicle ECU (4) determines that the vehicle has a risk of tire blowout. S4. The vehicle ECU (4) controls the execution of the emergency braking command: outputs a signal to the vehicle power module (5) to start limiting torque output; outputs a signal to the vehicle brake control module (6) to start wheel-end braking; at the same time, the in-vehicle acoustic alarm (7) and the external optical alarm (8) are activated. The in-vehicle acoustic alarm (7) reminds the people inside the vehicle to pay attention to the vehicle status, and the external optical alarm (8) reminds the people and vehicles outside the vehicle to pay attention to avoid the vehicle. S5. As the vehicle speed decreases or slows down to a stop, the vehicle temperature decreases accordingly until the real-time tire temperature value C3 is lower than the preset high tire temperature value C2, and the real-time tire temperature value C3 shows no upward trend. Once the risk is deemed eliminated, the emergency braking command is stopped.

10. The method for preventing tire blowout of automobiles according to claim 6 or 7, characterized in that: During vehicle operation, when the real-time tire temperature C rises rapidly, and within a set time period t1 of 5-10 minutes, the real-time tire temperature rises by more than 20℃-30℃ within 5-10 minutes, exceeding the preset temperature rise range value C1, and there is a continuous upward trend, the vehicle ECU (4) determines that there is a risk of tire blowout and controls the execution of an emergency braking command.
