摘要： A controller may have a plurality of self-diagnostic functions, each of which is configured for checking a function of an assigned hardware component of the controller. Each of the self-diagnostic functions may have at least one safety limit value, which is configured such that when the at least one safety limit value is exceeded the corresponding hardware component is switched off. Each of the self-diagnostic functions may have at least one quality limit value, the absolute value of which is smaller than an absolute value of the at least one safety limit value. The at least one quality limit value can be configured such that a quality-relevant state can be detected in the assigned hardware component when the at least one quality limit value is exceeded.

摘要： A multiphase electric motor is disconnectable from a DC voltage source by way of a control unit. Phase windings with connection lines can each be alternately connected via a high-side and a low-side switching element to a respective pole of the DC voltage source, and the connection lines each have a device for disconnecting the phase windings from the DC voltage source upon a fault. The control unit may monitor the switching elements for short-circuit faults, switch off the switching elements when a fault occurs, determine whether the switching element causing the fault is a high-side or a low-side switching element, switch on at least a second of the high-side or correspondingly at least a second of the low-side switching elements in addition to the switching element causing the fault to brake the electric motor, switch off the switching elements after a braking period, and open the phase disconnection devices.
