Abstract
A method for actuating contactors in a traction system. The traction system includes an AC battery, an electric motor, at least one peripheral unit, a plurality of voltage and current sensors, a plurality of contactors, which are arranged in electrical connections to the AC battery and to the electric motor and to the at least one peripheral unit, and a controller having a hardware-programmable processor unit on which a control program for actuating the contactors is configured at the start of operation. After the configuration, a fixed semiconductor circuit structure relating to the actuation of the contactors is available to the processor unit. The traction system has multiple modes of operation. A respective mode of operation is predefined by a general vehicle controller. A respective mode of operation has a plurality of states formed by at least one respective target state and at least one intermediate state.
