    摘要: The starting device for starting an internal combustion engine includes a starter motor (12) with a pinion for cranking the internal combustion engine; a voltage source (40) for the starter motor; a starter relay (14) for connecting and disconnecting the voltage source to and from the starter motor and an electronic relay (32) for triggering the starter relay according to control signals from the motor controller (50). The electronic relay (32) is mounted on the starter motor or in the starter relay. The electronic relay (32) includes a power module (34) with a redundancy circuit including two transistors (144', 144") coupled with each other by a logic circuit for preventing starter operation when one of the two transistors is defective.
