Method for operating an onboard power supply system (1) of a motor vehicle (21), which onboard power supply system (1) has at least one electrical power source and at least one load (6, 7, 8, 9), wherein some of the loads (6, 7, 8, 9) belong to a safety group of safety-relevant loads (8, 9), the operation of which needs to be assured even when the onboard power supply system (1) is heavily loaded, wherein for at least some of the loads (6, 7, 8, 9), particularly all the loads (6, 7, 8, 9), at least one voltage threshold value (16) is prescribed in each case, wherein each load (6, 7, 8, 9) itself monitors whether the onboard power supply voltage is below the voltage threshold value (16), and, if the onboard power supply voltage is below the voltage threshold value (16), the power draw of the respective load (6, 7, 8, 9) is reduced by the load (6, 7, 8, 9) itself. |
