[0045] Such as figure 1 As shown, in the first embodiment of the present invention, the tire maintenance prediction method of the present invention includes the following steps:

[0046] Step S110, obtaining the tire parameters of the vehicle under the current working condition; the tire parameters include at least one of vehicle load, vehicle speed, Z-direction acceleration, yaw moment, tire temperature and tire pressure;

[0047] In this embodiment, in order to solve the problem of not being able to accurately determine the tire wear condition of the vehicle under different operating conditions. The invention provides a tire maintenance prediction method. The method can obtain the tire parameters of the vehicle under different operating conditions, and input the tire parameters into a pre-trained prediction model, so as to obtain the tire life. After the tire life is obtained, the tire life is compared with a preset threshold. When the life of the tire reaches the preset ...

[0064] Such as figure 2 As shown, in the second embodiment of the present invention, step S220 in the second embodiment is located before step S110 in the first embodiment, and step S111-step S112 are refinement steps of step S110 in the first embodiment, and step S121- Step S122 is a refinement step of step S120 in the first embodiment. Include the following steps:

[0065] Step S110, obtaining the tire parameters of the vehicle under the current working condition; the tire parameters include at least one of vehicle load, vehicle speed, Z-direction acceleration, yaw moment, tire temperature and tire pressure;

[0066] Step S220, detecting whether the vehicle is equipped with a tire pressure monitoring system;

[0067] If so, execute step S111 to obtain the tire temperature and tire pressure detected by the tire pressure monitoring system under the current working condition of the vehicle;

[0068] If not, step S112 is executed to obtain the vehicle load, vehicle speed, Z-...

[0077] Such as image 3 As shown, in the third embodiment of the present invention, before step S110 based on the second embodiment, the following steps are further included:

[0078] Step S310, obtaining the steering wheel angle of the vehicle, and determining the driving state of the vehicle according to the steering wheel angle of the vehicle;

[0079] Step S320, when the driving state of the vehicle is a straight-line driving state, acquiring the position information of the vehicle;

[0080] Step S330, determining the offset value of the vehicle according to the position information;

[0081] Step S340, judging whether the offset value of the vehicle is within the first offset interval;

[0082] If yes, perform the step S220: detect whether the vehicle is equipped with a tire pressure monitoring system;

[0083] If not, execute step S350: when the offset value of the vehicle is in the second offset interval, generate four-wheel alignment correction information and send ...

Abstract

The invention discloses a tire maintenance prediction method and device and a computer readable storage medium, and belongs to the technical field of vehicle maintenance management. The method comprises the following steps: acquiring tire parameters of a vehicle under a current working condition; the tire parameters comprise at least one of vehicle load, vehicle speed, Z-direction acceleration, yawing moment, tire temperature and tire pressure; inputting the tire parameters into a pre-trained service life prediction model, so that the service life prediction model predicts the tire life of the vehicle according to the tire parameters; and when the service life of the tire reaches a preset threshold value, generating tire replacement reminding information corresponding to the vehicle, and sending the tire replacement reminding information to a user terminal to remind a user of replacing the tire, so that the problem that the wear condition of the tire under different use conditions cannot be accurately determined is solved, and the tire replacement reminding information is more accurate. According to the technical scheme, the service life of the tire is predicted, and the tire is maintained in time according to the service life of the tire.

Description

technical field [0001] The invention relates to the technical field of vehicle maintenance management, in particular to a tire maintenance prediction method and equipment, and a computer-readable storage medium. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. In order to ensure the mileage and performance of the tires, it is necessary to regularly check and maintain the tire pressure and tire wear. At present, tires are usually replaced according to a fixed number of kilometers or a fixed time. However, under different operating conditions, the wear of the tires is different, and it is impossible to accurately determine the wear of the tires under different operating conditions, which causes inconvenience to...
