Problems solved by technology

[0008] Measuring devices on the vehicle side cannot measure tire or wheel state variables with sufficient accuracy, since these measuring devices only measure the corresponding physical variables indirectly from outside the wheel or derive the corresponding variables from indirect measurements

Embodiment Construction

[0020] In the figures of the drawings, identical and functionally identical elements and features—unless otherwise described—are provided with the same reference signs.

[0021] The invention is explained in more detail below as an example of use in a motor vehicle. The method and the device for determining physical wheel state variables can of course be used not only in the wheels of motor vehicles, but also in the wheels of motorcycles, trucks or other commercial vehicles. It is also possible to determine corresponding tire or wheel state variables in aircraft wheels.

[0022] figure 1 A schematic block diagram of a device for determining physical wheel or tire state variables (hereinafter referred to as wheel state variables or wheel variables) in a motor vehicle is shown.

[0023] A vehicle wheel 10 generally has a rim 11 on which a tire 12 is placed (see figure 2 ). The tire 12 can be tubeless or also have a tube. Such a wheel 10 with corresponding tires 12 can be u...

Abstract

In order to more accurately determine wheel state variables of a wheel, physical variables of the wheels are continuously measured and evaluated on the vehicle side. In addition, physical variables of the wheel are intermittently measured on the wheel side. The variables measured on the wheel side or the evaluated measurement results thereof are used to correct the variables measured on the vehicle side and / or the determined wheel state variables.

Description

technical field [0001] The invention relates to a method and a device for continuously determining wheel state variables of a wheel. Background technique [0002] In vehicles, driving safety plays an important role, especially with regard to driving dynamics. For this purpose, the detection of static or dynamic physical variables related to the state of the tires or the state of the wheels, such as tire pressure or wheel load, is an important input variable in order to control and improve driving safety. Currently, such input variables can only be precisely determined with great effort or detected only over a very long period of time. Many physical parameters can only be determined indirectly by deriving third parameters. [0003] The determination of static or dynamic tire or wheel state variables, such as the wheel load, is usually carried out by additional systems on the vehicle. This means increased costs for additional components in the vehicle. [0004] Static or d...
