Electronic control device of an electric drive system, electronic drive unit of an electric drive system and electric drive system

摘要

In a normal operation, a central processing unit (7) of an electronic control device (2), - and actual values (w *, w) and determines therefrom nominal current values (i *), the it to an electronic drive unit (3) transmits. The central processing unit (13), the nominal current values (i *), from this, control signals (a *) for circuit breaker (15) and feeds it to the power switches (15) from. As a result, an electric motor (4) in accordance with the desired current value (i *) to a power supply (u) is switched on. In a monitoring operation checks the central processing unit (7) of the electronic control device (2), whether the electric motor (4) is in a safe state. It is not located in the safe state, it transmits to a first shut-off device (12) and on the drive unit (3) switch-off signals (a1, a2) so that the power supply (u) of the electric motor (4) is reliably interrupted. In addition generates the central processing unit (7) of the electronic control device (2) at least in the monitoring operation check information (p), the per se or in combination with at least one further in the monitoring operation of the drive unit (3) transmitted signal (i *) are characteristic for this purpose, whether the control device (2) functioning properly, and transmits them to the drive unit (3). The central processing unit (13) of the drive unit (3) in the monitoring operation checks whether its a switch-off signal (a2) is transmitted, whether it the ..
