Multi-phase electronic power converter () for outputting multi-phase alternating current, wherein for every phase the current converter () comprises a power output () controlled via at least two semiconductor switches () connected in a half-bridge circuit, wherein the electronic power converter () has a control device () which is configured for processing a target value signal of the control device () supplied as an input signal, each in the form of a bit stream () of one or more bits for every phase, characterized in that the control device () is configured by means of space-vector modulation to generate actuation signals (P, P, P) of the semiconductor switches () in relation to the bit streams () supplied as an input signal.

Electronic power converter and computer program

The invention relates to a control system () for a vehicle provided with an electronically controlled drive train () which comprises a steering system (), a braking system () and a transmission unit (). An operating unit () generates a motion vector (BV) based on a driver's wish (FW), from which control signals (SS) are generated by a control unit () for controlling the drive train (). In order to simplify maneuvering, more particularly reversing, a trajectory calculator () is provided, said trajectory calculator calculating the trajectory of movement for the situation and position of the vehicle () on the basis of actual values that are detected by a status and position determining device () and on the basis of set values that can be inputted by means of a target input device (). The trajectory of movement consists of a sequence of motion vectors (BV), which move the vehicle from its actual status and actual position to the set status and set position when the drive train () executes the motion vectors (BV) of the trajectory of movement. For said purpose, the trajectory calculator () is coupled to the operating unit () and additionally to the control unit () by means of a common drive train interface () for transmitting the motion vectors (BV).

Vehicle control system

The apparatus for producing mechanical stimulations by vibration of a tappet which is put on a human's skin comprises a measuring head, which on one hand has a housing, in which the back and forward moving tappet is arranged and on the other hand an actuating unit for this tappet. An acceleration sensor is attached to the tappet.
