Abstract: A method for the drive control of actuators of at least one wheel of a vehicle. The method includes: sensing a desired acceleration; sensing a vehicle velocity of the vehicle; sensing a wheel velocity of the wheel determining a status description of the wheel from the wheel velocity and a wheel acceleration; determining a first value of a target wheel acceleration from the status description, a slip of the wheel, and the desired acceleration; determining a second value of the target wheel acceleration from the wheel velocity, the wheel acceleration and the slip, wherein the second value is a function of correction factors of at least one matrix; and determining a third value of the target wheel acceleration, which value controls the actuators of the at least one wheel, wherein the third value is a function of the first value and of the second value.

Abstract: A method for operating a detection device for determining distance variables in which distances characterise objects detected by the detection device is disclosed. From at least one amplitude-modulated electrical send signal at least one scanning signal is generated, which is sent into at least one monitoring region of the detection device. From at least one echo signal of at least one scanning signal reflected in the at least one monitoring region at least one amplitude-modulated electrical receive signal is determined. From at least one electrical send signal and at least one electrical receive signal at least one distance variable is determined. When determining the at least one distance variable at least one adjustment is carried out. A temperature adjustment is carried out in which at least one temperature adjustment variable is applied to at least one distance variable.
