1. An operation controller that controls operations of a plurality of electrical loads mounted on a vehicle and having assigned priorities, comprising:

  • a start-up request accepting portion configured to accept a plurality of start-up requests from the electrical loads; and

    a start-up coordinating portion configured to control start-up of the electrical loads on the basis of the priorities so as to (1) start up both a first electrical load having a relatively high priority among the plurality of electrical loads and a second electrical load having a relatively low priority among the plurality of electrical loads when a power supply capacity is higher than a threshold, and (2) start up the first electrical load and output a second start-up restriction state signal for restricting start-up of the second electrical load when the power supply capacity is lower than or equal to the threshold, whereinwhen the start-up request accepting portion accepts a start-up request from the second electrical load in a state where the second electrical load has received the start-up restriction state signal, the start-up coordinating portion outputs a first start-up restriction state signal for restricting start-up of the first electrical load, andwhen the first electrical load is stopped after a predetermined waiting time elapses since the first start-up restriction state signal has been output, the start-up coordinating portion controls the second electrical load to start up.
