    摘要: A device and method for determining a roll angle of a motorcycle are disclosed. The method includes the step of acquiring a rolling rate ({dot over (λ)}M) of the motorcycle. A first roll angle variable (λ1) is determined from the rolling rate ({dot over (λ)}M). At least one vehicle movement dynamics characteristic variable is determined from a velocity (v), a rotational speed ({dot over (ψ)}M), and/or an acceleration ({umlaut over (z)}M, ÿM) of the motorcycle. A second roll angle variable (λ2) is determined from one or more vehicle movement dynamics characteristic variables. The roll angle (λE) is calculated on the basis of the roll angle variables (λ1, λ2).

    摘要: An allocation method combines two tire pressure monitoring systems in motor vehicles being equipped with pressure measuring modules. Each pressure measuring module records a value responsive to the tire inflation pressure and sends the latter to a receiving unit connected to an evaluating device together with an individual identification code (IDx) allocated to the respective pressure measuring module. Signals about the rotational speed of each one wheel being sensed by wheel rotational speed sensors are transmitted to the evaluating device, and since the installation positions y of the wheels at the vehicle are known to the evaluating device, the wheels at the vehicle are known, and the allocation method is performed by taking into consideration established probability values W_IDx_y, with the probability values W_IDx_y describing a frequency distribution which indicates how often pressure measuring modules with the identification codes IDx are detected as pertaining to the installation positions y.
