Problems solved by technology

[0004] In vehicle dynamics development, not only must the tire model be matched, but also the tire pressure must be adjusted according to the dynamic performance of the vehicle. If the tire pressure is adjusted to a higher value, it will have a better performance. If the tire pressure is adjusted to be lower, it will have better comfort and the handling will be correspondingly reduced, so it is impossible to satisfy the handling and handling on the road at the same time. Comfort on poor roads

Embodiment 1

[0043] The embodiment of the present invention provides a method for adjusting tire pressure, see figure 1 , the method includes:

[0044] 101: Obtain vehicle driving condition parameters;

[0045] 102: Adjust the tire pressure according to the driving condition parameter of the vehicle.

[0046] The method provided in this embodiment obtains the current driving state of the car, and dynamically adjusts the tire pressure according to the driving state and the current tire pressure signal, so that the car can automatically turn the tire when the road condition is good and the speed is high. Adjust the tire pressure to a higher tire pressure value, at this time the tire will have a higher cornering stiffness, thereby ensuring good handling stability of the car; and when driving on poor road surfaces, such as cement roads, potholes etc., the tire pressure will be automatically adjusted to a lower tire pressure value. At this time, the tire will have a lower vertical stiffness, ...

Embodiment 2

[0048] The embodiment of the present invention provides a method for adjusting tire pressure, see figure 2 , the method includes:

[0049] 201: Obtain the acceleration value of the wheel through the wheel acceleration sensor, the driving speed of the vehicle through the speed sensor, and the tire pressure signal of the tire obtained through the tire pressure sensor installed on the wheel;

[0050] In the embodiment of the present invention, the acceleration value of the wheel, the driving speed of the vehicle and the tire pressure signal of the tire are all parameters of the driving condition of the vehicle, which can be used to measure the current road condition of the vehicle and the specific state of the vehicle. Among them, the acceleration value of the wheel can be obtained by detecting the wheel when the vehicle is running due to road interference by the wheel acceleration sensor, the driving speed of the vehicle can be obtained by detecting the vehicle by the speed sen...

Embodiment 3

[0061] An embodiment of the present invention provides a tire pressure regulating system, see image 3 , the system consists of:

[0062] A parameter acquisition module 301, configured to acquire vehicle driving condition parameters;

[0063] see Figure 4 , the parameter acquisition module 301 includes:

[0064] Acceleration value obtaining unit 301a, used to obtain the acceleration value of the wheel;

[0065] A vehicle speed obtaining unit 301b, configured to obtain the driving speed of the vehicle;

[0066] The tire pressure signal acquiring unit 301c is configured to acquire the tire pressure signal of the tire.

[0067] The tire pressure adjustment module 302 is configured to adjust the tire pressure according to the vehicle driving condition parameters.

[0068] The tire pressure adjustment module 302 includes:

[0069] The tire pressure judging unit 302a is used for judging the tire pressure required by the current vehicle according to the acceleration value of t...

Abstract

The invention discloses a method and a system for regulating tire pressure of a tire, belonging to the field of vehicle control. The method comprises the steps of: acquiring vehicle drive condition parameters; and regulating the tire pressure of the tire according to the vehicle drive condition parameters. The system comprises a parameter acquiring module and a tire pressure regulating module. Through acquiring the driving state of a current vehicle, and the tire pressure of the tire is regulated according to the driving state and the current tire pressure signal state of the tire, therefore, the invention ensures that the vehicle can automatically regulate the tire pressure of the tire to be higher tire pressure value under the conditions of better road conditions and higher speed, at the moment, the tire has higher cornering stiffness, thereby ensuring good control stability of the vehicle; and when the vehicle runs on poorer roads, such as cement roads, uneven roads, and the like, the vehicle automatically regulates the tire pressure of the tire to be lower tire pressure value, at the moment, the tire has lower vertical stiffness, thereby immediately absorbing vertical shaking caused by uneven roads and improving the comfortableness of the whole vehicle.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a tire pressure regulating method and system. Background technique [0002] With the rapid development of the automobile industry, automobiles have gradually entered thousands of households, and people's understanding of vehicles has gradually increased. The demand for vehicles has changed from the original use requirements to higher requirements for vehicle performance. As a direct contact part between the car and the ground, the importance of tires is self-evident. Tires not only resist the forces in all directions generated during the daily use of the car, maintain the stability of the car, but also serve as a part of the car. The shock absorption system absorbs part of the excitation generated by the road to the car. [0003] After analyzing the prior art, the inventor finds that the prior art has at least the following disadvantages: [0004] In vehicle dynamics developme...
