Description

Technical Field

[0001] The present invention relates to the field of intelligent driving technology, and in particular to a method, device, electronic device and storage medium for stabilizing control of a vehicle tire blowout. Background Art

[0002] A tire blowout occurs when a tire loses most of its air in a very short period of time. Studies have shown that a large number of traffic accidents are caused by tire blowouts, and on highways, especially at speeds exceeding 120 km / h, the fatality rate is close to 100%, posing a serious threat to the driver's life.

[0003] To prevent tire blowouts, drivers need to constantly monitor tire wear and pressure, and promptly replace tires if any issues arise. In addition to proactive driver prevention, some automakers have also introduced their own tire blowout control solutions. Some manufacturers' tire blowout monitoring and safety control systems detect a blowout within approximately 0.5 seconds, and then the anti-lock braking system (ABS) and electronic brakeforce distribution (EBD) quickly initiate automatic braking. This ensures that the braking force generated by the healthy wheel on the opposite side of the blown wheel is greater than or close to the sum of the rolling resistance and braking force of the blown wheel. This effectively prevents yaw in the direction of the blowout, avoiding wheel locking that can lead to vehicle deviation, skidding, and tailspinning, ensuring vehicle safety and reliability. However, this solution requires an additional vacuum booster, which increases costs. Furthermore, the ABS and EBD systems require development and calibration for blowout conditions, further increasing costs, and therefore have several drawbacks. Summary of the Invention

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] A tire blowout occurs when a tire loses most of its air in a very short period of time. Relevant studies have shown that a large number of automobile traffic accidents are caused by tire blowouts. Moreover, on highways, especially when the speed is greater than 120km / h, it can lead to a mortality rate close to 100%, posing a serious threat to the driver's life safety.

[0045] To prevent tire blowouts, drivers need to constantly monitor tire wear and pressure, and promptly replace tires if any issues arise. In addition to proactive driver prevention, some automakers have also introduced their own tire blowout control solutions. For example, one manufacturer's tire blowout monitoring and safety control system detects a blowout within approximately 0.5 seconds. The ABS and EBD then rapidly initiate automatic braking, ensuring that the braking force generated by the healthy wheel on the opposite side of the blown wheel is greater than or close to the sum of the rolling resistance and braking force of the blown wheel. This effectively prevents yaw in the direction of the blowout, preventing wheel locking that can lead to vehicle deviation, skidding, and tailspinning, ensuring vehicle safety and reliability. However, this solution requires an additional vacuum booster, which increases costs. Furthermore, the ABS and EBD require development and calibration for blowout conditions, further increasing costs.

[0046] Another manufacturer's fourth-generation tire emergency safety device (Tesd) installs additional mechanical parts in the wheel groove to fill the inner diameter difference of the rim, preventing the tire from being rolled into the groove bottom or detaching from the rim after a loss of pressure. It also uses the deflated tire for effective support to form a rubber pad to prevent the metal wheel hub from directly touching the ground and slipping. This can effectively reduce costs, but it can only alleviate the problem and cannot play an active control role. It will also affect the comfort of the vehicle.

[0047] Based on this, the main core concept of this application is to switch the longitudinal torque control to lateral torque control through intelligent driving intervention after the vehicle has a tire blowout, thereby achieving control of the out-of-control vehicle and allowing the driver to safely stop the vehicle and wait for rescue.

[0048] like Figure 1 As shown, an embodiment of one aspect of the present invention provides a vehicle tire blowout stability control method, which is applied to a cabin, wherein the cabin is assembled on a mobile vehicle, and includes:

[0049] S1: Detect the tire pressure of each tire of the vehicle;

[0050] S2: Determine whether each tire of the vehicle has a tire blowout according to the tire pressure of each tire;

[0051] S3: performing a stabilization control operation on the vehicle based on the tire that has blown out, the stabilization control operation at least including: switching the longitudinal control torque to a lateral control torque.

[0052] The present invention provides a method for controlling a vehicle with a tire blowout, which detects the tire pressure of each tire of the vehicle to determine whether each tire has a blowout. The method then performs a stability control operation on the vehicle in combination with the lateral control torque, thereby laterally controlling the vehicle with a tire blowout and offsetting the tendency to sideways caused by torque imbalance after the tire blowout.

[0053] In the embodiment of the present application, a tire pressure detection device can be used to detect the tires of the vehicle. The tire pressure monitoring system (TPMS) is an early warning system that can automatically detect the tire pressure and temperature of the vehicle and alarm for abnormal tire conditions.

[0054] Currently, direct TPMS transmitter modules primarily utilize two solutions: 1) battery + microcontroller + sensor + RF chip; 2) battery + sensor with an integrated MCU + RF chip. These systems can be categorized into two types: an indirect tire pressure monitoring system (TPMS) uses tire rotational speed differences to determine tire anomalies. A direct TPMS, however, utilizes four tire pressure monitoring sensors installed inside the tires to automatically monitor tire pressure and temperature in real time, whether the vehicle is stationary or moving. These sensors provide prompt alerts for high, low, or high tire pressure, preventing accidents caused by tire failure and ensuring driving safety. Indirect TPMS, also known as WSBTPMS, relies on the vehicle's ABS (anti-lock braking system) wheel speed sensors to compare tire rotational speed differences to monitor tire pressure. ABS uses these wheel speed sensors to determine wheel lock and decide whether to activate the ABS. When tire pressure decreases, the vehicle's weight reduces the tire diameter, causing a change in vehicle speed. This speed change triggers the WSB warning system, alerting the driver to insufficient tire pressure. Therefore, indirect TPMS is a passive TPMS. Direct tire pressure monitoring systems, also known as PSB TPMS, use tire-mounted pressure sensors to measure tire pressure and temperature. A wireless transmitter transmits this pressure information from inside the tire to a central receiver module, which then displays the tire pressure data. The system issues an alarm when high, low, or high tire pressure is detected. Tire pressure and temperature alarm ranges can be customized based on vehicle model, driving habits, and geographic location. Therefore, direct TPMS is an active TPMS, and is highly favored for its stable performance, high accuracy, and strong sensitivity.

[0055] Furthermore, in the embodiment of the present application, the method steps of the above embodiment also include:

[0056] S01: Determine the vehicle's yaw state based on the lane line and the vehicle's heading;

[0057] Correspondingly, the performing a stabilization control operation on the vehicle based on the tire that has blown out includes: performing a stabilization control operation on the vehicle according to the yaw state of the vehicle and the front-rear position of the tire that has blown out.

[0058] In this embodiment, the vehicle is stabilized and controlled in combination with the yaw state and the tire blowout state, thereby eliminating the influence of the yaw state. If the vehicle yaws, it can be corrected through lateral control.

[0059] Specifically, the vehicle is stabilized and controlled according to the yaw state of the vehicle and the front and rear positions of the tire with a blown tire, such as Figure 2 As shown, including:

[0060] S001: If the vehicle is in a non-yaw state and a front wheel of the vehicle has a tire blowout, the longitudinal control torque of the front wheel is switched to the lateral control torque, and the braking torque is gradually increased;

[0061] S002: If the vehicle is in a non-yaw state and a rear wheel of the vehicle has a tire blowout, the longitudinal control torque of the rear wheel is switched to a lateral control torque, and a set braking torque is applied at set time intervals;

[0062] S003: If the vehicle is in a yaw state, the longitudinal control torque of the tire-punctured wheel is switched to the lateral control torque, and the braking torque is controlled to the maximum value.

[0063] In this application, the vehicle's own intelligent driving LCK system can be used. At this time, the vehicle loses control performance for about 3 seconds due to a tire blowout while driving at high speed, which is basically consistent with the driver's operation reaction time. After the tire blowout, the vehicle loses control. At this time, the most important thing is to keep the vehicle stable in the lane. Therefore, the currently existing LCK function can be used as a basis, combined with appropriate braking to achieve the purpose of controlling the vehicle with a tire blowout.

[0064] For example, in this embodiment, if the front tire blows out, it is controlled by combining LCK control and slow braking of the intelligent driving system. LCK controls the lateral stability of the vehicle, and applying slow braking not only reduces the yaw of the tire-blown wheel, but also reduces the vehicle speed, minimizing the damage, and allowing the vehicle to pull over. When the rear tire blows out, LCK control is combined with repeated short braking. The purpose of repeated short braking is to achieve deceleration and mitigate lateral deviation while also increasing safety and avoiding excessive deviation correction. If the vehicle still deviates significantly from the lane after control, emergency heavy braking is applied to correct the vehicle's deviation, and then LCK control is resumed. When the vehicle's state stabilizes and environmental conditions permit, to ensure safety, pull-over control is performed, and roadside assistance and other comfort measures are automatically called.

[0065] It can be understood that if both the front and rear tires are blown, yaw will inevitably occur, that is, at this time the longitudinal control torque of the blown wheel is switched to the lateral control torque, and the control braking torque is N times the maximum braking torque, where N is greater than 1.

[0066] The above embodiment first differentiates between front and rear tires. The inventor discovered that when a tire blows, the rapidly increased rolling resistance of the blown wheel generates a large torque around the vehicle's center of mass, causing the vehicle to yaw. Furthermore, this force is transmitted to the steering wheel through the steering mechanism. Pulling the steering wheel toward the blown wheel exacerbates the yaw. At this point, the driver can hold the steering wheel tightly to maintain directional stability and apply moderate braking to balance the torque generated by the rolling resistance. The steering wheel of a vehicle with a rear tire blowout can turn freely, but the rolling resistance of the rear tire blowout also generates a large yaw torque on the vehicle, causing the vehicle to yaw and drift in the opposite direction of the blown wheel. Furthermore, a vehicle with a rear tire blowout is highly susceptible to yaw to the outside of the curve during a turn, leading to oversteer accidents. Therefore, after discovering the differences between the front and rear tires, the applicant configured differentiated control strategies for the front and rear tires.

[0067] Furthermore, in a preferred embodiment, detecting the tire pressure of each tire of the vehicle includes:

[0068] The tire pressure detected by the tire pressure sensor corresponding to each tire is obtained at every set period.

[0069] In a preferred embodiment, the set period is greater than 300ms. In this embodiment, to ensure real-time tire blowout detection, the tire pressure monitoring system detection period must be kept within 300ms. However, due to the power supply design of the TPMS sensor, the TPMS sensor detection frequency is correlated to battery life, so current mass production solutions are all in the second range. After repeated research, the inventors ultimately selected a sensor period of approximately 550ms. While slightly longer than a blowout, it can still detect a blowout without affecting vehicle stability and control.

[0070] Furthermore, in a preferred embodiment, the performing a stability control operation on the vehicle based on the tire that has blown out includes: performing a stability control operation on the vehicle based on the tire that has blown out in combination with the vehicle speed and road congestion conditions.

[0071] In this preferred embodiment, vehicle stability control is performed in combination with vehicle speed and road congestion conditions, thereby further considering road condition information, making stability control more accurate and practical.

[0072] In a more preferred embodiment, based on the tire that has punctured, the vehicle is subjected to stability control operations in combination with the vehicle speed and road congestion conditions, such as Figure 3 As shown, including:

[0073] S011: Generates maximum braking torque based on vehicle speed and road congestion;

[0074] S012: If the yaw state of the vehicle is not yawed and the front wheel of the vehicle has a tire blowout, the longitudinal control torque of the front wheel is switched to the lateral control torque, and the braking torque is gradually increased to the maximum braking torque within a set time period;

[0075] S013: If the vehicle's yaw state is not yawed and a rear wheel of the vehicle has a tire blowout, the longitudinal control torque of the rear wheel is switched to the lateral control torque, and the maximum braking torque is applied at a set time interval;

[0076] S014: If the yaw state of the vehicle is yawed, the longitudinal control torque of the tire-punctured wheel is switched to the lateral control torque, and the braking torque is controlled to be N times the maximum braking torque, where N is greater than 1.

[0077] Specifically, if Figure 4 As shown, step S011 specifically includes:

[0078] S0111: generating a road congestion coefficient according to the road congestion situation, wherein the road congestion coefficient is inversely proportional to the road congestion degree;

[0079] S0112: Calculate the product of the vehicle speed and the road congestion coefficient, and generate a maximum braking torque based on the product.

[0080] It can be seen that this application determines the maximum braking torque based on the road congestion and vehicle speed, thereby taking into account the influence of road congestion and vehicle speed. In the event of a tire blowout, braking can be performed based on the current road conditions, avoiding excessive braking in congested road conditions and causing rear-end collisions, making braking more precise and safer.

[0081] For example, the degree of road congestion can be divided into congested, normal, and unobstructed. Each degree of road congestion corresponds to a proportional coefficient, for example, congested corresponds to 0.11, normal corresponds to 0.55, and unobstructed corresponds to 0.95. That is, the higher the congestion level, the smaller the proportional coefficient.

[0082] The vehicle speed is then deducted using the above-mentioned proportional coefficient, and the maximum braking torque is determined using the deduction result. Braking is then performed around the maximum braking torque, which can greatly improve the safety factor and stability of the vehicle.

[0083] Through the above embodiments, it can be seen that the present application, based on the basic theoretical model, performs lateral control on a vehicle with a tire blowout to offset its tendency to sideways due to torque imbalance after the tire blowout. The application is divided into two scenarios: when the intelligent driving function is turned on and when it is not turned on. When a tire blowout occurs when the intelligent driving function (LCK) is turned on, the car is still in a non-yawed state. When the TPMS does not recognize the tire blowout, it still determines the vehicle's yaw state based on the lane line and the vehicle's heading and applies control to prevent the vehicle's heading from deviating significantly. After the tire blowout information is recognized, a tire blowout warning is issued and the longitudinal control torque is exited. At the same time, different control logics are output according to the detected tire blowout location. The stable control method for a vehicle with a tire blowout provided by the present invention detects the tire pressure of each tire of the vehicle and then determines whether each tire has a tire blowout. Then, the vehicle is stabilized by combining the lateral control torque, thereby performing lateral control on the vehicle with the tire blowout to offset its tendency to sideways due to torque imbalance after the tire blowout.

[0084] This application provides a vehicle tire blowout stability control device at the software level, such as Figure 5 As shown, including:

[0085] Detection module 1, detecting the tire pressure of each tire of the vehicle;

[0086] a tire blowout determination module 2, which determines whether each tire of the vehicle has a tire blowout according to the tire pressure of each tire;

[0087] The stabilization operation module 3 performs a stabilization control operation on the vehicle based on the tire that has blown out. The stabilization control operation at least includes: switching the longitudinal control torque to a lateral control torque.

[0088] It can be seen from the above embodiments that the stability control device for a vehicle with a tire blowout provided by the present invention is configured with an acquisition module, a negative emotion determination module, and a stability control module for a vehicle with a tire blowout. By detecting the tire pressure of each tire of the vehicle, it is determined whether each tire has a blowout. Thereafter, a stability control operation is performed on the vehicle in combination with the lateral control torque, thereby laterally controlling the vehicle with a tire blowout and offsetting its side deviation tendency caused by torque imbalance after the tire blowout.
