[0031] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0032] In the related art, for the identification of a tire blowout of a vehicle, the current state of the tire can be analyzed by collecting the temperature and pressure of the tire, so as to maintain the vehicle tire and reduce the risk of tire blowout of the vehicle; or the tire pressure change can be monitored in real time by a controller to monitor the tire blowout, and after the tire blowout is identified, the steering wheel can be locked, the brake can be started to brake slowly, and the injector can be controlled to stop spraying oil to avoid traffic accidents caused by the tire blowout; or the probability of tire blowout can be calculated by a fusion method, such as the fusion of the tire pressure of the four wheels and the change in the tire pressure of the wheels, to warn the driver in advance, and after the tire blowout, the steering system can be locked first, and then the tire force feedforward control and yaw rate feedback control can be used to restore the vehicle to stable straight driving and detect the parking condition; or by reasonably enabling ABS (Antilock Brake System) or ESP (Electronic Stability Program) braking, the tire blowout accident can be handled in straight driving and turning driving conditions, and vehicle stability control can be performed, and various safety operations can be performed in combination with the change in vehicle distance.

[0033] However, the above solutions all use tire pressure monitoring to identify tire blowouts. The identification method is single and there is a problem of slow response speed in tire blowout identification. In scenarios where the response speed of tire blowout identification is required, it is impossible to identify whether the vehicle will have a tire blowout, for example, a tire blowout caused by a sudden encounter with a sharp object, which reduces the vehicle's driving safety and the user's driving experience.

[0034] Therefore, the tire blowout identification method for a vehicle according to the embodiment of the present invention is adopted to determine the tire blowout confidence of the target tire through the vehicle's driving parameters, and output the tire blowout signal of the vehicle according to the target tire blowout confidence, so as to realize rapid identification of the tire blowout of the vehicle in more driving scenarios, thereby improving the driving safety of the vehicle and the user's driving experience.

[0035] Combine the following Figure 1-Figure 2 A method for identifying a tire blowout of a vehicle according to an embodiment of the present invention is described.

[0036] like Figure 1 FIG. 1 is a flow chart of a method for identifying a tire blowout of a vehicle according to an embodiment of the present invention. The method according to the present invention at least comprises steps S1 and S2.

[0037] Step S1, determining the confidence level of a target tire blowout according to the driving parameters of the vehicle.

[0038] In an embodiment, the driving parameters of the vehicle are data collected in real time by sensors on the vehicle during real-time operation of the vehicle, including but not limited to suspension height, four-wheel speed, four-wheel tire pressure, vehicle yaw angular velocity, and steering wheel angle; tire blowout confidence refers to the probability of a tire blowout under specific conditions; and the target tire blowout confidence is direct data for determining the probability of a tire blowout.

[0039] When determining the target tire blowout confidence according to the vehicle's driving parameters, first, the vehicle's driving parameters need to be pre-processed, such as filtering, to obtain filtered data. Since the wheel speeds of the four wheels will differ significantly when the vehicle turns, in order to avoid the interference of non-blowout factors in the wheel speed information caused by turning, it is necessary to correct the four-wheel speeds to overcome the difference caused by turning, and obtain the corrected vehicle driving parameters; secondly, obtain the driving parameter blowout confidence corresponding to the corrected driving parameters. The driving parameter blowout confidence includes: tire pressure blowout confidence, tire pressure change blowout confidence, wheel speed change blowout confidence, and suspension height blowout confidence. In order to determine the corrected driving parameter blowout confidence The data is prepared by using the modified driving parameter tire blowout confidence degree, and the processed multiple types of driving parameters are used to determine the modified driving parameter tire blowout confidence degree, so that the tire blowout recognition of the vehicle is more accurate, the recognition is faster, and the tire blowout recognition is applicable to more scenarios, for example, it can be applicable to abnormal tire blowout scenarios not caused by tire aging, such as tire blowout due to sharp objects; finally, at least one of the modified driving parameter tire blowout confidence degrees is weighted to determine the target tire blowout confidence degree, because the driving parameters and other information used in determining the target tire blowout confidence degree are all obtained by real-time monitoring of various sensors of the vehicle, and the types of driving parameters used are diverse, so the confirmation of the target tire blowout confidence degree is faster, more stable, and applicable to more driving scenarios.

[0040] Step S2: outputting a tire blowout signal of the vehicle according to the target tire blowout confidence level.

[0041] In an embodiment, when outputting a tire blowout signal of a vehicle according to a target tire blowout confidence, for example, taking a left front wheel blowout as an example, the methods for determining tire blowouts of other wheels are similar and will not be repeated here. If the left front wheel target tire blowout confidence is greater than the left front wheel target tire blowout confidence threshold, the left front wheel blowout flag is activated, for example, the activation flag is set to 1, the left front wheel blowout signal of the vehicle is output, and the left front wheel blowout alarm is triggered, and the process of the subsequent blowout control function is output; if the left front wheel target tire blowout confidence is less than or equal to the left front wheel target tire blowout confidence threshold, the left front wheel blowout flag is not activated, and the confidence saturation link is entered. At the next moment, that is, at t=t+1, the real-time data of the vehicle is reacquired, and the next cycle of determining the target tire blowout confidence according to the vehicle's driving parameters and outputting the vehicle's blowout signal according to the target tire blowout confidence is entered. Since the vehicle's tire blowout signal is obtained based on the target tire blowout confidence, and the fusion recognition algorithm is used in determining the target tire blowout confidence and determining the vehicle's tire blowout signal, the fusion recognition algorithm, for example, an algorithm that performs weighted processing on at least one of the modified driving parameter tire blowout confidences, can quickly identify the vehicle's tire blowout, thereby achieving rapid identification of the vehicle's tire blowout in more driving scenarios, thereby improving the vehicle's driving safety and the user's driving experience.

[0042] According to the vehicle tire blowout identification method of the embodiment of the present invention, the tire blowout confidence of the target tire is determined by the vehicle's driving parameters, and the vehicle's tire blowout signal is output according to the target tire blowout confidence, so as to realize rapid identification of the vehicle's tire blowout in more driving scenarios, thereby improving the vehicle's driving safety and the user's driving experience.

[0043] In some embodiments, determining a target tire blowout confidence level based on driving parameters of the vehicle includes: acquiring a driving parameter blowout confidence level; correcting the driving parameter blowout confidence level to obtain a corrected driving parameter blowout confidence level; and determining the target tire blowout confidence level based on the corrected driving parameter blowout confidence level.

[0044] In an embodiment, the driving parameters of the vehicle are data collected in real time by sensors on the vehicle during real-time operation of the vehicle, including but not limited to suspension height, four-wheel speed, four-wheel tire pressure, vehicle yaw angular velocity, and steering wheel angle; tire blowout confidence refers to the probability of a tire blowout under specific conditions; and driving parameter tire blowout confidence refers to the probability of a tire blowout corresponding to each driving parameter of the tire.

[0045] Before calculating the confidence level of tire blowout caused by driving parameters, the driving parameters of the vehicle need to be filtered to obtain filtered data. Since the wheel speeds of the four wheels will differ significantly when the vehicle turns, in order to avoid the interference of non-tire blowout factors in the wheel speed information caused by turning, the wheel speeds of the four wheels need to be corrected to overcome the differences caused by turning.

[0046] For example, by default, the vehicle can only steer the front wheels. The longitudinal velocity component of the four-wheel speed is extracted, and the four-wheel speed is corrected according to the yaw angular velocity according to the following formula

[0047]

[0050] in, , , and They are the corrected wheel speed values ​​of the left front wheel, right front wheel, left rear wheel and right rear wheel respectively; , , and They are the filtered wheel speed signals of the left front wheel, right front wheel, left rear wheel and right rear wheel respectively; and are the left front wheel angle and the right front wheel angle respectively, is the yaw angular velocity, and They are the front axle track.

[0051] If there is no special angle sensor for measuring the left front wheel angle and the right front wheel angle, the table can be looked up according to the calibration result of the vehicle model and the steering wheel angle. For the steering wheel angle values ​​that do not appear in the value interval in the table, the Euler interpolation method or the fourth-order Runge-Kutta interpolation method and other methods are used to interpolate the existing values ​​in the table adjacent to the value to obtain the front wheel angle value under the steering wheel angle. The left front wheel and the right front wheel are interpolated and queried according to the steering wheel angle to obtain the corresponding values ​​of the left front wheel angle and the right front wheel angle, as shown in Table 2, which is an approximate corresponding relationship table of the steering wheel angle and the left front wheel of a certain vehicle model in one embodiment of the present invention. Table 2 provides the corresponding relationship between the steering wheel angle and the left front wheel of a certain vehicle model.

[0052]

[0058] The calculation of the tire pressure changes of the four tires is as follows:

[0063] When determining the target tire blowout confidence according to the vehicle's driving parameters, the driving parameter blowout confidence is obtained. The driving parameter blowout confidence includes: tire pressure blowout confidence, tire pressure change blowout confidence, wheel speed change blowout confidence, and suspension height blowout confidence. Data preparation is done to determine the initial tire blowout confidence, and the initial tire blowout confidence is determined by the processed multiple types of driving parameters, so that the vehicle's tire blowout recognition is more accurate and faster, and the blowout recognition is applicable to more scenarios, for example, it can be applicable to abnormal blowout scenarios such as tire blowout due to sharp objects that are not caused by tire aging.

[0064] The driving parameter tire blowout confidence level is corrected to obtain the corrected driving parameter tire blowout confidence level, so as to prepare for determining the target tire blowout confidence level.

[0065] The target tire blowout confidence is determined according to the corrected driving parameter blowout confidence, and the target tire blowout confidence is used to identify whether the vehicle will have a blowout, so as to quickly identify the vehicle's blowout in more driving scenarios, thereby improving the vehicle's driving safety and the user's driving experience.

[0066] In some embodiments, correcting the driving parameter tire blowout confidence to obtain the corrected driving parameter tire blowout confidence includes: when the first driving parameter is less than the first driving parameter tire blowout threshold, increasing the driving parameter tire blowout confidence according to the first tire blowout confidence adjustment amount to obtain the corrected driving parameter tire blowout confidence; when the first driving parameter is greater than or equal to the first driving parameter tire blowout threshold, reducing the driving parameter tire blowout confidence according to the first tire blowout confidence adjustment amount to obtain the corrected driving parameter tire blowout confidence; when the second driving parameter is greater than the second driving parameter tire blowout threshold, increasing the driving parameter tire blowout confidence according to the second tire blowout confidence adjustment amount to obtain the corrected driving parameter tire blowout confidence; when the second driving parameter is less than or equal to the second driving parameter tire blowout threshold, reducing the driving parameter tire blowout confidence according to the second tire blowout confidence adjustment amount to obtain the corrected driving parameter tire blowout confidence.

[0067] In an embodiment, the wheel speed change value, tire pressure value, tire pressure change value, and suspension height value of each wheel on the vehicle are monitored in real time. At each moment, the driving parameter tire blowout confidence includes: tire pressure tire blowout confidence, tire pressure change tire blowout confidence, wheel speed change tire blowout confidence, and suspension height tire blowout confidence; the modified driving parameter tire blowout confidence includes: modified tire pressure tire blowout confidence, modified tire pressure change tire blowout confidence, modified wheel speed change tire blowout confidence, and modified suspension height tire blowout confidence; the first driving parameter includes: at least one of the tire pressure value, tire pressure change value, and vehicle suspension height difference value, wherein the vehicle suspension height difference value includes: the height of the left front suspension and the height of the right rear suspension The first driving parameter tire blowout threshold corresponds to the first driving parameter including: tire pressure blowout threshold, tire pressure change threshold and tire suspension height blowout threshold; the second driving parameter includes tire wheel speed change value, wherein the threshold values ​​are all critical values ​​of the tire that will blow out obtained according to demand and experiments; the second driving parameter tire blowout threshold corresponds to the second driving parameter including tire wheel speed change threshold, wherein the threshold values ​​are all critical values ​​of the tire that will blow out obtained according to demand and experiments; the first tire blowout confidence adjustment amount and the second tire blowout confidence adjustment amount are both values ​​obtained according to vehicle model, demand or experimental calibration.

[0068] When the driving parameter tire blowout confidence is corrected to obtain the corrected driving parameter tire blowout confidence, when the first driving parameter is less than the first driving parameter tire blowout threshold, the driving parameter tire blowout confidence is increased according to the first tire blowout confidence adjustment amount to obtain the corrected driving parameter tire blowout confidence. For example, taking the left front wheel tire blowout as an example, the tire blowout determination methods of the remaining wheels are similar and will not be repeated here. If the tire pressure value and / or tire pressure change value and / or vehicle suspension height difference of the left front wheel are less than the tire pressure threshold, the tire pressure blowout confidence and / or tire pressure change will be adjusted according to the first tire blowout confidence adjustment amount. The confidence level and / or suspension height tire blowout confidence level are adjusted accordingly, the first tire blowout confidence level adjustment amount is to correspondingly increase the tire pressure tire blowout confidence level increment and / or the tire pressure change tire blowout confidence level increment and / or the suspension height tire blowout confidence level of the left front wheel, and the adjusted confidence level is used as the corresponding corrected tire pressure tire blowout confidence level and / or the corrected tire pressure change tire blowout confidence level and / or the corrected suspension height tire blowout confidence level of the left front wheel; the driving parameter tire blowout confidence level is adjusted by judging that the first driving parameter is less than the first driving parameter tire blowout threshold, so that the obtained corrected driving parameter tire blowout confidence level is more accurate.

[0069] When the first driving parameter is greater than or equal to the first driving parameter tire blowout threshold, the driving parameter tire blowout confidence is reduced according to the first tire blowout confidence adjustment amount to obtain a modified driving parameter tire blowout confidence. For example, taking the left front wheel tire blowout as an example, the tire blowout determination methods of the remaining wheels are similar and will not be repeated here. If the tire pressure value and / or tire pressure change value and / or vehicle suspension height difference of the left front wheel is greater than or equal to the tire blowout pressure threshold, the tire pressure tire blowout confidence and / or tire pressure change tire blowout confidence and / or suspension height tire blowout will be adjusted according to the first tire blowout confidence adjustment amount. The confidence is adjusted accordingly, and the first tire blowout confidence adjustment amount is to reduce the tire pressure blowout confidence reduction and / or the tire pressure change blowout confidence reduction and / or the suspension height blowout confidence reduction of the left front wheel accordingly, and the adjusted confidence is used as the corresponding corrected tire pressure blowout confidence and / or the corrected tire pressure change blowout confidence and / or the corrected suspension height blowout confidence of the left front wheel; the driving parameter blowout confidence is adjusted by judging that the first driving parameter is greater than or equal to the first driving parameter blowout threshold, so that the obtained corrected driving parameter blowout confidence is more accurate.

[0070] When the second driving parameter is greater than the second driving parameter tire blowout threshold, the driving parameter tire blowout confidence is increased according to the second tire blowout confidence adjustment amount to obtain a corrected driving parameter tire blowout confidence. For example, taking the left front wheel tire blowout as an example, the tire blowout determination methods of the remaining wheels are similar and will not be repeated here. If the tire wheel speed change value of the left front wheel is greater than the tire speed change threshold, the wheel speed change tire blowout confidence will be adjusted according to the second tire blowout confidence adjustment amount. The second tire blowout confidence adjustment amount is to increase the wheel speed change tire blowout confidence increment. The adjusted confidence is used as the corrected driving parameter tire blowout confidence of the left front wheel, so that the obtained corrected driving parameter tire blowout confidence is more accurate.

[0071] When the second driving parameter is less than or equal to the second driving parameter tire blowout threshold, the driving parameter tire blowout confidence is reduced according to the second tire blowout confidence adjustment amount to obtain a corrected driving parameter tire blowout confidence. For example, taking the left front wheel tire blowout as an example, the tire blowout determination methods of the remaining wheels are similar and will not be repeated here. If the tire wheel speed change value of the left front wheel is less than or equal to the tire speed change threshold, the wheel speed change tire blowout confidence will be adjusted according to the second tire blowout confidence adjustment amount. The second tire blowout confidence adjustment amount is to reduce the tire blowout confidence deduction by reducing the wheel speed change. The adjusted confidence is used as the corrected driving parameter tire blowout confidence of the left front wheel, so that the obtained corrected driving parameter tire blowout confidence is more accurate.

[0072] The confidence formula for determining the modified driving parameter of tire pressure value is:

[0073] in, is the tire pressure threshold for a tire burst, is the tire pressure burst confidence increment, Confidence reduction for tire pressure burst; The confidence formula for determining the modified driving parameter of tire pressure change value is:

[0074] in, is the tire pressure change threshold for a tire burst, is the tire pressure change tire blowout confidence increment, The confidence reduction for tire blowout due to tire pressure change; The confidence formula for determining the modified driving parameter tire blowout for the vehicle suspension height difference is:

[0075] in, is the suspension height threshold for tire blowout, is the confidence increment of suspension height tire blowout, Confidence reduction for suspension height blowout; The confidence formula for determining the modified driving parameter of tire burst for the tire speed change value is:

[0076] in, is the tire burst wheel speed change threshold, is the tire burst confidence increment due to wheel speed change, The confidence reduction for tire blowout due to wheel speed change.

[0077] In some embodiments, the driving parameter tire blowout confidence degree is corrected to obtain the corrected driving parameter tire blowout confidence degree, including: when the driving parameter tire blowout confidence degree is higher than the driving parameter tire blowout confidence degree upper limit value, determining the corrected driving parameter tire blowout confidence degree according to the driving parameter tire blowout confidence degree upper limit value; when the driving parameter tire blowout confidence degree is lower than the driving parameter tire blowout confidence degree lower limit value, determining the corrected driving parameter tire blowout confidence degree according to the driving parameter tire blowout confidence degree lower limit value.

[0078] In an embodiment, the driving parameter tire blowout confidence upper limit value corresponds to the driving parameter tire blowout confidence including: tire pressure tire blowout confidence upper limit value, tire pressure change tire blowout confidence upper limit value, wheel speed change tire blowout confidence upper limit value, suspension height tire blowout confidence upper limit value; the driving parameter tire blowout confidence lower limit value corresponds to the driving parameter tire blowout confidence including: tire pressure tire blowout confidence lower limit value, tire pressure change tire blowout confidence lower limit value, wheel speed change tire blowout confidence lower limit value, suspension height tire blowout confidence lower limit value; wherein, the driving parameter tire blowout confidence upper limit value is obtained by actual vehicle test calibration, and the driving parameter tire blowout confidence lower limit value is obtained according to demand and experiment, and can usually be taken as 0.

[0079] When the driving parameter tire blowout confidence is higher than the driving parameter tire blowout confidence upper limit value, the modified driving parameter tire blowout confidence is determined according to the driving parameter tire blowout confidence upper limit value. For example, taking the left front wheel tire blowout as an example, the tire blowout determination methods of the other wheels are similar and will not be repeated here. If the tire pressure tire blowout confidence of the left front wheel is higher than the tire pressure tire blowout confidence upper limit value, then the modified tire pressure tire blowout confidence of the left front wheel is equal to the tire pressure tire blowout confidence upper limit value; if the tire pressure change tire blowout confidence of the left front wheel is higher than the tire pressure change tire blowout confidence upper limit value, then the modified tire pressure change tire blowout confidence of the left front wheel is equal to the tire pressure change tire blowout confidence upper limit value; if the wheel speed change tire blowout confidence of the left front wheel is higher than If the tire blowout confidence level due to wheel speed change is higher than the upper limit value of the tire blowout confidence level due to wheel speed change, then the corrected tire blowout confidence level due to wheel speed change of the left front wheel is equal to the upper limit value of the tire blowout confidence level due to wheel speed change; if the tire blowout confidence level due to suspension height of the left front wheel is higher than the upper limit value of the tire blowout confidence level due to suspension height, then the corrected tire blowout confidence level due to suspension height of the left front wheel is equal to the upper limit value of the tire blowout confidence level due to suspension height of the left front wheel; by judging that the tire blowout confidence level due to driving parameters is higher than the upper limit value of the tire blowout confidence level due to driving parameters, the corrected tire blowout confidence level due to driving parameters is obtained to avoid the potential safety hazard caused by the tire blowout confidence level due to driving parameters being higher than the upper limit value of the tire blowout confidence level due to driving parameters, so that the corrected tire blowout confidence level due to driving parameters is within the upper limit value of the tire blowout confidence level due to driving parameters.

[0080] When the driving parameter tire blowout confidence is lower than the driving parameter tire blowout confidence lower limit, the modified driving parameter tire blowout confidence is determined according to the driving parameter tire blowout confidence lower limit. For example, taking the left front wheel tire blowout as an example, the tire blowout determination methods of the remaining wheels are similar and will not be repeated. If the tire pressure tire blowout confidence of the left front wheel is lower than the tire pressure tire blowout confidence lower limit, then the modified tire pressure tire blowout confidence of the left front wheel is equal to the tire pressure tire blowout confidence lower limit; if the tire pressure change tire blowout confidence of the left front wheel is lower than the tire pressure change tire blowout confidence lower limit, then the modified tire pressure change tire blowout confidence of the left front wheel is equal to the tire pressure change tire blowout confidence lower limit; if the wheel speed change tire blowout confidence of the left front wheel is lower than If the tire blowout confidence level due to wheel speed change is lower than the lower limit of the tire blowout confidence level due to wheel speed change, then the corrected tire blowout confidence level due to wheel speed change of the left front wheel is equal to the lower limit of the tire blowout confidence level due to wheel speed change; if the tire blowout confidence level due to suspension height of the left front wheel is lower than the lower limit of the tire blowout confidence level due to suspension height, then the corrected tire blowout confidence level due to suspension height of the left front wheel is equal to the lower limit of the tire blowout confidence level due to suspension height of the left front wheel; the corrected driving parameter tire blowout confidence level is obtained by judging that the driving parameter tire blowout confidence level is lower than the lower limit of the driving parameter tire blowout confidence level, so as to avoid the potential safety hazard caused by the driving parameter tire blowout confidence level being lower than the lower limit of the driving parameter tire blowout confidence level, and to ensure that the corrected driving parameter tire blowout confidence level is above the lower limit of the driving parameter tire blowout confidence level.

[0081] The formula for determining the confidence level of corrected tire pressure burst is:

If the left front wheel target tire blowout confidence is greater than the left front wheel target tire blowout confidence threshold, the left front wheel blowout flag is activated, for example, the activation flag is set to 1, the left front wheel tire blowout signal of the vehicle is output, and the left front wheel tire blowout alarm is triggered, and the process of the subsequent tire blowout control function is output; if the left front wheel target tire blowout confidence is less than or equal to the left front wheel target tire blowout confidence threshold, the left front wheel tire blowout flag is not activated, and the confidence saturation link is entered. At the next moment, that is, at t=t+1, the real-time data of the vehicle is reacquired, and the next cycle of determining the target tire blowout confidence according to the vehicle's driving parameters and outputting the vehicle's tire blowout signal according to the target tire blowout confidence is entered. The formula is as follows
