20100060262 | ROTATIONAL DIRECTION DETECTOR AND METHOD FOR DETERMINING THE DIRECTION OF ROTATION OF A WHEEL - A rotational direction detector is specified which is provided for mounting to a circumferential segment of a wheel having at least one sensor, wherein a change in the output signal of the sensor occurs when the circumferential segment enters and/or leaves the wheel contact area. Furthermore a method is specified for determining the direction of rotation of a wheel, wherein the signal change is determined and a rotational direction signal is derived therefrom. | 03-11-2010 |
20100063669 | METHOD AND MEASUREMENT SYSTEM FOR LOCALIZING AT LEAST ONE WHEEL ON A MOTOR VEHICLE - A method and a measurement system are specified for localizing at least one wheel on a motor vehicle. In this case the operating situation of the motor vehicle and the wheel load of the at least one wheel and/or a variable dependent on this is determined. Then the at least one measured value of the wheel load is compared with a value assigned to the operating situation. As an alternative or in addition, the comparison of at least one parameter dependent on at least two measured values can be undertaken with at least one of the parameters assigned to this operating situation. Finally the point on the motor vehicle at which the wheel is mounted is determined on the basis of the comparison results. | 03-11-2010 |
20100063671 | METHOD AND MEASURING SYSTEM FOR DETERMINING A WHEEL LOAD - A method and a measuring system determine a wheel load. These involve measuring a deformation of a tire and using a set of equations and equation parameters to calculate from the deformation the wheel load acting on the tire. In addition, a wheel load or a variable dependent on the load, which is used to calculate the wheel load, is received from an external system. Finally, the two wheel loads determined in different ways are compared, and the equations and/or equation parameters are adapted on the basis of the comparison. | 03-11-2010 |
20100308987 | Method for the Operation of Wheel Electronics, Wheel Electronics, and Tire Checking System - A method for operating wheel electronics of a tire checking system includes providing wheel electronics having a battery-free power supply encompassing at least one rechargeable power storage medium for supplying power to the wheel electronics. The wheel electronics can be operated in a reduced-power transmission mode and a subsequent normal transmission mode. In the modes, data that relate to tire-specific parameters and are determined by the wheel electronics are transmitted to a vehicle-mounted communication device in the form of modulated transmission signals, with less transmission power being used for the transmission signals in the power-reduced transmission mode than in the normal transmission mode. Wheel electronics and a tire checking system are also provided. | 12-09-2010 |

20110282548 | METHOD AND DEVICE FOR CONTINUOUSLY DETERMINING WHEEL STATE VARIABLES OF A WHEEL - 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. | 11-17-2011 |
20120011926 | DEVICE AND METHOD FOR MEASURING THE TREAD DEPTH OF A MOTOR VEHICLE TIRE - A device and a method for measuring the tread depth of a motor vehicle tire. The device includes at least one sensor element which is configured to acquire data on a change of the deformation characteristics of the motor vehicle tire in the area of the tire contact area and can be fixed in the area of the inner side of the motor vehicle tire opposite the tread; and a control and evaluation unit for evaluating and processing the acquired data. The unit is data-connected to the at least one sensor element. | 01-19-2012 |
