[0002] During car driving, tires are the only medium for the vehicle to contact the ground, and their status is directly related to driving safety.

[0003] In the related art, when a user is driving a vehicle, if a tire of the vehicle is deflated, the user often continues driving until a repair point is found. However, when a tire of the vehicle is deflated, the user continues driving until a repair point is found, which may cause the risk of a tire blowout. Summary of the invention

[0004] In view of this, the present invention provides a vehicle control method, apparatus, computer equipment, storage medium and program product.

[0005] In a first aspect, the present invention provides a vehicle control method, the method comprising: obtaining a tire pressure value of a target vehicle within a target time period; wherein the tire pressure value is an air pressure value in a cavity formed between a wheel hub and an inner wall of a rubber tire; determining a tire pressure change rate of the target vehicle based on the tire pressure value of the target vehicle within the target time period; when the tire pressure change rate of the target vehicle meets a preset condition, adjusting the tire pressure value of the target vehicle so that the tire pressure value of the target vehicle is within a preset safety range.

[0006] The vehicle control method provided in this embodiment can effectively prevent tire blowout accidents caused by excessively high or low tire pressure by real-time monitoring of tire pressure and timely adjustment when the pressure is abnormal, thereby ensuring driving safety. In addition, maintaining appropriate tire pressure can increase the friction between the tire and the ground, thereby enhancing the braking performance of the vehicle, shortening the braking distance, and improving the ability to avoid danger in emergency situations.

[0007] In one possible implementation, the tire pressure change rate of the target vehicle is determined based on the tire pressure value of the target vehicle within the target time period, including: determining the tire pressure reduction amount between the tire pressure values ​​of the target vehicle at two adjacent moments within the target time period; determining the tire pressure change rate of the target vehicle based on the time difference between the two adjacent moments and the tire pressure reduction amount between the tire pressure values ​​of the target vehicle at the two adjacent moments.

[0008] The vehicle control method provided in this embodiment can accurately capture the slight change of tire pressure in a short period of time by calculating the tire pressure reduction between two adjacent moments, thereby more accurately reflecting the real-time status of the tire.

[0012] In the vehicle control method provided in this embodiment, the target vehicle is equipped with an air pump, and the air outlet of the air pump is cleverly set on the inner wall of the wheel hub and equipped with a controllable valve. When the tire pressure value of the target vehicle needs to be adjusted, the valve is opened by controlling the air pump controller, and the air pump is accurately controlled to inflate the tire through its air outlet according to the tire pressure change rate. Maintaining appropriate tire pressure can effectively prevent the occurrence of tire blowout accidents and improve driving safety.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] According to an embodiment of the present invention, a vehicle control method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] In this embodiment, a vehicle control method is provided, which can be used in a vehicle computer system. Figure 1 is a flow chart of a vehicle control method according to an embodiment of the present invention, such as Figure 1 As shown, the process includes the following steps:

[0027] Step S101, obtaining the tire pressure value of the target vehicle within the target time period, wherein the tire pressure value is the air pressure value in the cavity formed between the wheel hub and the inner wall of the rubber tire.

[0028] The target vehicle may be any vehicle to which the method provided by the embodiments of the present disclosure may be applied.

[0029] The tire pressure value of the target vehicle may represent the air pressure value in the cavity formed between the wheel hub and the inner wall of the rubber tire.

[0030] In a possible implementation, the target vehicle receives tire pressure values ​​at a preset time interval. As an example, the preset time interval is 1S.

[0031] The target time period is a sub-time period within the time period of a process of acquiring the tire pressure value of the target vehicle.

[0032] In the process of obtaining the tire pressure value of the target vehicle, steps S101-S102 are repeatedly executed. The number of times steps S101-S102 are executed is recorded as m.

[0033] In the process of obtaining the tire pressure value of the target vehicle once, if the kth execution of steps S101-S102 determines that the tire pressure change rate of the target vehicle does not meet the preset condition, then the k+1th execution of steps S101-S102 is performed. If the mth execution of steps S101-S102 determines that the tire pressure change rate of the target vehicle meets the preset condition, then S103 is performed. Both k and k+1 are less than m.

[0034] Step S102, determining the tire pressure change rate of the target vehicle according to the tire pressure value of the target vehicle within the target time period.

[0035] The tire pressure change rate of the target vehicle can characterize the rate of change of the tire pressure value in each sub-time period within the target time period. Specifically, the acquired tire pressure value of the target vehicle is processed to calculate the change rate of the tire pressure value within the target time period. For example: a target time period can be the time period for the target vehicle to travel from the starting position to the target position. Among them, the target time period can include multiple sub-time periods, and the sub-time periods can be multiple preset time intervals. The tire pressure value of the target vehicle will be detected in each sub-time period, so as to obtain the tire pressure values ​​of multiple target vehicles in the sub-time period, and then the tire pressure change rate of the target vehicle is calculated by the tire pressure values ​​of the target vehicle in two adjacent sub-time periods.

[0036] Step S103, when the tire pressure change rate of the target vehicle meets the preset condition, the tire pressure value of the target vehicle is adjusted to make the tire pressure value of the target vehicle within a preset safety range.

[0037] The preset condition may indicate a change rate threshold value of the target vehicle's tire pressure leakage. When the tire pressure change rate of the target vehicle satisfies the preset condition, the tire pressure value of the target vehicle is adjusted so that the tire pressure value of the target vehicle is within a preset safety range.

[0038] As an example, the four tires of the target vehicle may be inspected separately, and each tire may be judged whether there is air leakage through the above steps S101 to S102.

[0039] The vehicle control method provided in this embodiment can effectively prevent tire blowout accidents caused by excessively high or low tire pressure by real-time monitoring of tire pressure and timely adjustment when the pressure is abnormal, thereby ensuring driving safety. In addition, maintaining appropriate tire pressure can increase the friction between the tire and the ground, thereby enhancing the braking performance of the vehicle, shortening the braking distance, and improving the ability to avoid danger in emergency situations.

[0040] In a possible implementation, the above step S102 includes:

[0041] Step a1: determining the tire pressure reduction amount between the tire pressure values ​​of the target vehicle at two adjacent moments within the target time period.

[0042] Two adjacent moments can be represented as two time points immediately before and after on the time axis. The tire pressure value of the target vehicle is detected at each moment, so that the tire pressure values ​​at two moments can be obtained, and the tire pressure reduction can be obtained by subtracting the tire pressure value at the previous moment from the tire pressure value at the latter moment.

[0043] Step a2, determining the tire pressure change rate of the target vehicle according to the time difference between two adjacent moments and the tire pressure drop between the tire pressure values ​​of the target vehicle at two adjacent moments.

[0044] The tire pressure change rate is obtained by dividing the tire pressure drop by the time difference. For example, if the time difference between two adjacent moments is 3 minutes and the tire pressure drop is 0.2 bar, then the tire pressure change rate is 0.2 bar / 3 minutes = 0.006 bar / minute.

[0045] The vehicle control method provided in this embodiment can accurately capture the slight change of tire pressure in a short period of time by calculating the tire pressure reduction at two adjacent moments, thereby more accurately reflecting the real-time status of the tire.

[0046] In a possible implementation, the method further includes: when the tire pressure change rate of the target vehicle meets a preset condition, sending an alarm message to a terminal device of the user.

[0047] The user's terminal device may be a mobile phone, a tablet computer, a wearable watch, etc., which are not specifically limited here. The warning information may be information notifying that the vehicle has a gas leak.

[0048] As an example, the warning message may be "the vehicle's tire is currently leaking air."

[0049] When the tire pressure change rate of the target vehicle meets the preset conditions, it can be determined that the tire of the target vehicle has an air leak, and the vehicle's on-board system can send an alarm message to the user's terminal device.

[0050] In a possible implementation, when the tire pressure change rate of the target vehicle meets a preset condition, a warning message is broadcast to the user through a voice device configured on the target vehicle.

[0051] The voice device can be a device that serves the voice dialogue flow of the vehicle, etc. When the tire pressure change rate of the target vehicle meets the preset conditions, it can be determined that the tire of the target vehicle is leaking, and the vehicle's on-board system can send the alarm information to the voice device of the target vehicle for broadcasting.

[0052] In one possible implementation, when the tire pressure change rate of the target vehicle meets a preset condition, an alarm message is broadcast to the user through a voice device configured on the target vehicle.

[0053] In the vehicle control method provided in this embodiment, the warning information on the terminal device reminds the user through visual stimulation, while the broadcast warning of the voice device is through auditory stimulation, both of which can effectively prompt the user.

[0054] In a possible implementation, the target vehicle is equipped with an air pump, the air outlet of the air pump is arranged on the inner wall of the wheel hub and a controllable valve is arranged at the air outlet; wherein, in the above step S103, the tire pressure value of the target vehicle is adjusted, including:

[0055] Step b1, controlling the air pump controller to open the valve.

[0056] Step b2, controlling the air pump controller to inflate the tire of the target vehicle through the air outlet of the air pump according to the tire pressure change rate.

[0057] Please refer to Figure 2 , Figure 2 A schematic diagram showing the communication between a trip computer, an air pump, a tire, and a tire pressure sensor of a target vehicle is shown.

[0058] The air pump controller is a device used to control the start, stop and adjust the working state of the air pump. The driving computer obtains the tire pressure value sent by the tire pressure sensor, and then determines the tire pressure change rate of the target vehicle based on the tire pressure value. When the tire pressure change rate of the target vehicle meets the preset conditions, the air pump outlet is controlled to inflate the target vehicle to adjust the tire pressure value of the target vehicle so that the tire pressure value of the target vehicle is within the preset safety range.

[0059] In the vehicle control method provided in this embodiment, the target vehicle is equipped with an air pump, and the air outlet of the air pump is cleverly set on the inner wall of the wheel hub and equipped with a controllable valve. When the tire pressure value of the target vehicle needs to be adjusted, the valve is opened by controlling the air pump controller, and the air pump is accurately controlled to inflate the tire through its air outlet according to the tire pressure change rate. Maintaining appropriate tire pressure can effectively prevent the occurrence of tire blowout accidents and improve driving safety.
