Patent ID: 7948113

Claim:
A power supply management system for a motor vehicle comprising: means for detecting operating conditions of electric loads to determine required amounts of electric power to be required by the electric loads, the electric loads having a priority thereamong; means for determining a distribution of amounts of the electric power to be distributed to the electric loads from an electric power source in the motor vehicle based on the required amounts of electric power from the electric loads; means for supplying amounts of the electric power to the electric loads in accordance with the distribution of the amounts of the electric power; means for determining whether a request for distributing the corresponding required amount of the electric power is sent from at least one of the electric loads; means for determining, when it is determined that the request for distributing the corresponding required amount of the electric power is sent from the at least one of the electric loads, whether an alternative electric load is higher in priority than the at least one electric load included in the electric loads and whether the alternative electric load is in an on-state; and means for restricting an amount of the electric power to be supplied to the at least one of the electric loads when it is determined that the alternative electric load is higher in priority than the at least one electric load included in the electric loads and the alternative electric load is in the on-state.
