Abstract: An N-phase electric machine, N being an integer ?3, includes a housing; i×N stator windings arranged in a fixed manner in the housing, i being an integer ?2; and a rotatable rotor surrounded by the i×N stator windings in the housing. The stator windings are consecutively divided into i subgroups in a circumferential direction, each subgroup having N stator windings. The electric machine further comprises i current control modules and i temperature measurement devices, each current control module being correspondingly electrically connected to the N stator windings in one corresponding subgroup, so that when the stator windings in the i subgroups are supplied with power by the i current control modules, a rotating magnetic field is generated around the rotor. Each temperature measurement device is configured to measure the temperature of one corresponding subgroup in the i subgroups during operation of the electric machine.

Abstract: A method is proposed for maneuvering a vehicle. The vehicle has a steer-by-wire steering system having a steering handle and a steering gear actuator for changing a travel direction of the vehicle. In a manual driving operating state, a maneuvering process is detected based on a steering specification at the steering handle and a vehicle velocity. A target vehicle trajectory correlated with a driver intention for the maneuvering process is ascertained or predicted based on the steering specification at the steering handle and an environmental condition. An actual vehicle trajectory is progressively compared during the maneuvering process to the target vehicle trajectory. The actual vehicle trajectory is corrected in the event of a deviation from the target vehicle trajectory by means of a maneuvering assistance function and by an assisting intervention of the maneuvering assistance function in a lateral control of the vehicle.

Abstract: The invention relates to a control circuit (27) for a waste heat recovery system (2) for a heat engine (36). The waste heat recovery system (2) comprises at least one evaporator (21) for converting waste heat from the exhaust gas (31, 31a) generated by the heat engine (36) into a working medium (23), at least one expansion machine (24) which can be driven by the working medium (23), at least one condenser (25) for condensing the working medium (23a) expanded in the expansion machine (24) into the liquid state (23b), and at least one conveying device (26) for increasing the pressure of the condensed working medium (23b) and conveying same into the evaporator (21). The control circuit (27) influences at least one control variable which controls the energy transmission from the exhaust gas (31, 31a) to the working medium (23b) and/or the energy transmission from the working medium (23c) to the expansion machine (24).
