摘要： A method for validating a vehicle-to-X message, in which the message is received by an antenna arrangement having a least two antenna elements connected with a communication device. An electromagnetic field strength of the message is recorded based on different reception characteristics with different power densities, wherein the message includes an absolute position of a transmitter, and an absolute position of a receiver determined on the basis of global satellite navigation or on a map comparison. A first relative position of the transmitter is calculated from the absolute positions of the receiver and the transmitter. A second relative position is calculated from the ratio of the power densities or read out from a reference diagram. If a comparison of the first and second relative positions reveals a large degree of correspondence, the message is validated, and if a large degree of deviation is detected, the message is rejected.

In this method, a torque-forming current (iq) and/or a magnetic field attenuating current (id) are adjusted in a co-ordinate system which is fixed relative to the rotor, voltages in the co-ordinate system fixed relative to the rotor are detected to serve as control variables, and are transformed, on the basis of the measured rotor position, into a voltage phasor which indicates for each phase winding of the stator a voltage to be applied, and a set value for the magnetic field attenuating current (id) is limited to a maximum value depending on the measured speed of rotation of the rotor, said maximum value being preferably determined from a predetermined characteristic map. The invention further relates to an electronic controller and to a brake system.

摘要： The invention relates to a method for operating an electronically commutated synchronous machine, which comprises a stator having at least two, in particular three, phase windings and a rotor having at least one permanent magnet, wherein a control factor is determined periodically for each individual phase winding, and the time periods during which an upper and a lower supply voltage is applied to said phase winding via switches of an actuation circuit which are assigned to the phase winding are determined on the basis of said control factor. In accordance with the invention, the electronically commutated synchronous machine is actuated according to a method for space vector modulation, in which zero vectors are applied to the phase windings at the beginning and/or at the end of a period for a switch-off duration, wherein in each case either all of the switches connected to the upper supply voltage or all of the switches connected to the lower supply voltage are on, and wherein the selection of the zero vector, i.e. whether the conductive connection to the upper or the lower supply voltage is produced, is performed in accordance with the phase winding with the greatest, in magnitude, deviation from the average control factor, which expediently corresponds to the average of the upper supply voltage and the lower supply voltage. In addition, the invention relates to an actuation circuit and the use thereof.

摘要： The invention relates to a method for operating a synchronous machine which comprises a permanently excited rotor and a stator provided with a phase coil consisting in determining the rotor position. According to said invention, for rectifying a possible winding error, at least one current and/or voltage vector having a defined duration is applied to the phase winding of the unloaded synchronous machine in the direction of the determined position of the rotor. Such a measure constrains the orientation of the rotor of the synchronous machine in the corresponding angular position and ensures that the rotor is situated in a predetermined angular position.

摘要： The invention relates to a method for determining the rotor position of a stationary or slowly rotating synchronous machine by evaluating electrical test pulses that are obtained by applying voltage pulses to the individual phase windings of the stator. According to the inventive method, changes in the inductance of the phase windings caused by saturation of the stator iron according to the rotor position are determined in opposite current directions by calculating differences in the amount of current of two test pulses, angular values that are predefined as a result of the number of phase windings being assigned to the differences in the amount of current. In order to increase the measurement accuracy of said method, a bias pulse IVorm whose polarity is inverted in relation to the first test pulse Imess1 is generated before the first test pulse Imess1, the switch-on times t1 of the associated voltage pulses UVorm and -Umess1 being identical, and each first test pulse Imess1 generated in the respective phase winding (U, V, W) acts as a bias pulse in the same phase winding (U, V, W).
