CONTROLLER FOR A MULTI-VOLTAGE ON-BOARD POWER SUPPLY SYSTEM IN A VEHICLE

摘要

The invention relates to a controller (1) for a multi-voltage on-board power supply system in a vehicle. The controller (1) comprises a first control module (11) that is connected by means of a first supply path (A) to a first supply voltage connection (111) of the controller (1) and/or to a first earth connection (112) of the controller (1) in order to have current supplied to it at a first supply voltage; and a second control module (12) that is connected by means of a second supply path (B) to a second supply voltage connection (121) of the controller (1) and/or to a second earth connection (122) of the controller (1) in order to have current supplied to it at a second supply voltage. According to the invention, the second supply path (B) contains a circuit module (13) that is designed to either turn off or turn on the second supply path (B) on the basis of an actuation signal (1-1).
