Abstract: An intelligent power generation module includes: an electric motor including a motor housing, an inverter disposed at a first side of the motor housing and including an inverter housing configured to accommodate an insulated gate bipolar transistor (IGBT), an inner housing disposed inside the motor housing, and a dual flow path disposed at a circumferential surface of the motor housing on which the inner housing is disposed. The dual flow path includes a plurality of first cooling flow paths spaced apart from each other and through which a first fluid flows, a second cooling flow path defined between the plurality of first cooling flow paths and through which a second fluid flows, and a plurality of injection nozzles disposed at each of the plurality of first cooling flow paths, spaced apart from each other, and configured to spray the first fluid to an inner space of the inner housing.

Abstract: A method for the geometric representation of a vehicle area (1) of a vehicle for the purpose of collision detection, wherein the vehicle area (1) has a boundary (2), comprising the method steps of performing a medial axis transformation of the vehicle area (1) to generate a vehicle area skeleton (4) and performing a point classification of points of the vehicle area skeleton (4) to determine front corner region points (5, 6) and rear corner region points (7, 8), and a front wheelbase point (9) and a rear wheelbase point (10), and also performing a circle decomposition of the vehicle area (1), wherein each circle of the circle decomposition has a maximum area exceedance value (17).
Abstract: An intelligent power generation module includes a motor having a motor housing; a cooling water flow path; a first oil flow path extending along a circumferential direction of the motor housing such that oil flows through one end portion of the motor housing; a plurality of first injection nozzles being spaced apart from each other in a circumferential direction of the first oil flow path and configured to inject the oil into the motor housing; an oil injection housing mounted at the other end portion of the motor housing; a second oil flow path formed along a circumferential direction of the oil injection housing such that oil flows inside the housing for oil injection; and a plurality of second injection nozzles being spaced apart from each other in a circumferential direction of the second oil flow path and configured to inject the oil into the motor housing.

Abstract: The invention relates to a device for rejecting interference signals in bipolar voltage sources, in particular in high-voltage sources in a powertrain of an electric vehicle, wherein an amplifier circuit is provided, with an input stage the input of which is symmetrically connected by means of an electrically isolated tap to a positive power line and a negative power line of a voltage source in order to tap an interference signal, and with an output stage, actuated by the input stage, the output of which is symmetrically connected in each case via an output capacitor to the positive power line and the negative power line, in order to feed in a correction signal.
