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.

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.
