1. A vehicle comprising:

  • an engine;

    an electrical bus;

    a first set of electrical components configured to demand current from the electrical bus while the engine is on and demand no current while the engine is off;

    a second set of electrical components configured to demand current from the electrical bus while the engine is off and demand no current while the engine is on; and

    at least one controller programmed to selectively turn the engine off in response to an expected change in current demand on the bus that would (i) result from turning the engine off and (ii) cause total current demand to be less than a predetermined threshold and, in response to the engine being off, control current demands for the first set and the second set to match the expected change that resulted in turning the engine off.
