Abstract

The invention relates to a method for operating an internal combustion engine (1) having an exhaust-gas aftertreatment device (2) which has at least one first oxygen-storing-capable exhaust-gas catalytic converter (3) and an electronic control unit (7) with the aid of which lambda control is carried out. The invention furthermore relates to an electronic control unit (7) and a computer program product for carrying out the method. For lambda control, first direct control interventions are carried out by means of a first control unit (RE_1) on the basis of the first sensor signal (Sig1), which is representative of a first oxygen fraction in the exhaust gas mass flow (11a) directly upstream of the first exhaust-gas catalytic converter (3), and second temporary direct control interventions by means of a second control unit (RE_2) on the basis of the second sensor signal (Sig2), which is representative of a second oxygen fraction in the exhaust gas mass flow (11a) directly downstream of the first exhaust-gas catalytic converter (3). In this case, a remaining I fraction, including an adaptation fraction (AD), which remaining I fraction is determined on the basis of the second sensor signal (Sig2) by means of an I controller unit (RE_1), is fed to the first controller unit (RE_1), for permanent offset correction, wherein an adaptation of the adaptation fraction (AD) is carried out on the basis of an ongoing evaluation (Aw) of the second temporary control interventions with regard to the frequency and/or intensity and/or duration thereof.

Abstract

A high voltage cover may include a plate, legs, L-bends, and a hook. The plate of the high voltage cover may cover an access port leading to high voltage electrical connectors between a power electronics unit and of an electric motor. The hook of the high voltage cover may couple with a plug when the plug is coupled to the power electronics unit. The hook coupling with the plug may prevent uncovering the access power, and similarly the high voltage electrical connectors, until the plug is disconnected. The voltage is thereby removed from the high voltage electrical connectors when the plug is disconnected.

Abstract

Provided in the present invention are an electronic oil pump and a printed circuit board thereof. The printed circuit board used in an electronic oil pump comprises a three-phase inverter circuit with a phase-A transistor, a phase-B transistor and a phase-C transistor, and electric-motor terminal insertion holes for respective phases of a three-phase electric motor, wherein the electric-motor terminal insertion hole for the phases of the three-phase electric motor are each located between the transistors of the corresponding phases of the three-phase inverter circuit. Comparing with an existing printed circuit board used in an electronic oil pump, the printed circuit board used in an electronic oil pump in the embodiments of the present invention can increase the wiring area and heat dissipation area for a power signal on the printed circuit board and reduce the circuit transmission impedance, thereby reducing the heating of the printed circuit board itself and electromagnetic interference exerted by the printed circuit board to the outside.

Abstract

An internal gear pump, comprising a driving shaft (13), a pump rotor assembly (20), and a housing (30). The driving shaft (13) and the pump rotor assembly (20) are each rotatably mounted to the housing (30) about an axial direction, the driving shaft (13) is drivingly connected to the pump rotor assembly (20) to drive the pump rotor assembly (20), the pump rotor assembly (20) comprises an outer ring gear (21) and an inner gear (22), and the inner gear (22) eccentrically meshes with and is arranged radially inside the outer ring gear (21) to generate a pumping force. The outer ring gear (21) is torsionally connected to the driving shaft (13), and the inner gear (22) is rotatably supported on a support structure fixed relative to the housing (30), such that the driving shaft (13) drives, by means of the outer ring gear (21), the inner gear (22) to rotate. Therefore, a support structure for the driving shaft can be reduced, making the internal gear pump easier to assemble.

Abstract

The invention describes a method for detecting currents flowing in an inverter (IN1, IN1') or between the inverter (IN1, IN1') and an electric machine (EM) which has multiple phases and is connected to the inverter (IN1, IN1'). Currents (I1 – I3, I1' – I3') flowing in half-bridges (H1 – H3, H1' – H3') of the inverter (IN1, IN1'), which provides the currents as pulse-width-modulated phase currents for the electric machine (EM), are determined. The determination can be carried out by measuring at least one current (I1 – I3, I1' – I3') at the end of a determination period (E) and by estimating current values. The current values are estimated to form currents that cannot be measured with a predefined minimum accuracy on account of interference during the determination period (E). The estimation is carried out on the basis of previously determined current values. The current (I1 – I3, I1' – I3') flowing at the end of the determination period (E) in a half-bridge (H1) to be measured is determined by estimation if the determination period (E) takes place less than a predetermined decay time (tA) after a switching edge (SF) in another half-bridge (H1 – H3, H1' – H3') of the inverter (IN1, IN1'). Otherwise, it is determined by measuring the current for the half-bridge (H1) to be measured. The invention also describes a method for controlling an electric traction drive, and a current determination device.

CLUTCH ASSEMBLY AND POWER TRANSMISSION MECHANISM

Abstract

A clutch assembly and a power transmission mechanism. The clutch assembly (40) comprises: a first switchable one-way clutch (41), a second switchable one-way clutch (42) and a gear-shifting sleeve (43), wherein the first switchable one-way clutch (41) and the second switchable one-way clutch (42) are arranged on two opposite ends of the gear-shifting sleeve (43) in the axial direction of the clutch assembly (40); the first switchable one-way clutch (41) and the second switchable one-way clutch (42) each have a fully disconnected mode in which torque cannot be transmitted and a one-way clutch mode in which torque can be transmitted when a predetermined condition is met; and the gear-shifting sleeve (43) can move in the axial direction to selectively enable the two switchable one-way clutches to switch between the fully disconnected mode and the one-way clutch mode, thereby achieving different gear positions of the power transmission mechanism. The power transmission mechanism comprises a transmission shaft (10), a first gear (20), a second gear (30), and the clutch assembly (40). When each switchable one-way clutch is switched from the fully disconnected state to the one-way clutch mode, it is simply unnecessary to adjust the rotational speeds of a driving member and a driven member to be almost the same; thus, the system response time can be shortened, improving the gear shifting efficiency.
