Method and apparatus for driving and controlling on-vehicle loads
First Claim
1. An apparatus for driving and controlling a plurality of on-vehicle electrical loads, comprising:
- an on-vehicle power supply configured to generate power to be supplied the loads to each of which a priority is given, the plurality of priorities being used for distributing the power to the loads;
a power calculating device configured to calculate a current available amount of the power to be supplied from the power supply;
a priority changing device configured to change one or more of the priorities on the basis of inputted information in relation to a vehicle condition, the information including conditions of the loads;
a command producing device configured to produce a command value indicative of an amount of the power to be supplied to each of the loads by using the priorities, a sum of the power to be supplied to each load being kept within the available amount of the power to be supplied; and
a controller configured to control the power to be distributed to each of the loads on the basis of the command value.

Abstract
In an apparatus for driving and controlling plural on-vehicle electrical loads, an on-vehicle power supply generates power to be supplied the loads each having a priority. A power calculating device calculates a current available amount of the power to be supplied from the power supply, and a priority changing device changes one or more of the priorities on the basis of inputted information about a vehicle condition, the information including conditions of the loads. A command producing device produces a command value indicative of an amount of the power to be supplied to each of the loads by using the priorities. In this case, a sum of the power to be supplied to each load is kept within the available amount of the power to be supplied. A controller controls the power to be distributed to each of the loads on the basis of the command value.

22. An apparatus for driving and controlling a plurality of on-vehicle electrical loads, comprising:
-
an on-vehicle power supply configured to generate power to be supplied to the loads to each of which a priority is given the plurality of priorities being used for distributing the power to the loads;
a power calculating device configured to calculate a current available amount of the power to be supplied from the power supply, a power-consumption calculating device calculating at least one of an amount of necessary power of each load and an amount of minimum necessary power of each load on the basis of information inputted in relation to a vehicle condition, the necessary power being defined as power consumption of each load on condition that the apparatus is in normal operation in supplying the power to the load and the minimum necessary power being defined as power necessary for at the minimum a function of each load;
a command calculating device calculating a command value indicative of an amount of the power to be supplied to each of the loads by using the priorities and the amount of at least one of the necessary power and the minimum necessary power, a sum of the power to be supplied to each load being kept within the available amount of the power to be supplied; and
a controller configured to control the power to be distributed to each of the loads on the basis of the command value. - View Dependent Claims (23, 24, 25, 26, 27, 28)

29. A method for driving and controlling a plurality of on-vehicle electrical loads, comprising the steps of:
-
generating power to be supplied the loads to each of which a priority is given, the plurality of priorities being used for distributing the power to the loads;
calculating a current available amount of the power to be supplied from the power supply;
changing one or more of the priorities on the basis of inputted information in relation to a vehicle condition, the information including conditions of the loads;
producing a command value indicative of an amount of the power to be supplied to each of the loads by using the priorities, a sum of the power to be supplied to each load being kept within the available amount of the power to be supplied; and
controlling the power to be distributed to each of the loads on the basis of the command value.

30. An apparatus for driving and controlling a plurality of on-vehicle electrical loads, in which an on-vehicle power supply is provided to generate power to be supplied the loads to each of which a load priority is given, the load priority indicative of a priority order for supplying the power among the loads, the apparatus comprising:
-
a power calculating device configured to calculate a current available amount of the power to be supplied from the power supply;
a first calculating device configured to calculate an amount of first power to be supplied to each load group on the basis of a group priority indicative of a priority order for supplying the power among the load groups, each load group being any one of a plurality of groups obtained by dividing the plurality of loads, a sum of the first power to each load group being kept within the available amount of the power;
a second calculating device configured to calculate an amount of second power to be supplied to each load belonging to any load group on the basis of the load priority, a sum of the second power to each load belonging to the load group being kept within the amount of the first power supplied to the load group; and
a controller configured to control the power to be distributed to each of the loads on the basis of a power command value indicative of the amount of the first power to each load. - View Dependent Claims (31, 32, 33, 34, 35, 36)
