Abstract
A system for a vehicle includes a fuel control module and a voltage setting module. The fuel control module cuts off fuel to an engine during a deceleration fuel cutoff (DFCO) event. During the DFCO event, the voltage setting module monitors a brake pedal position, sets a desired voltage to a first predetermined voltage when a brake pedal is not depressed, and sets the desired voltage to a second predetermined voltage when the brake pedal is depressed. The second predetermined voltage is greater than the first predetermined voltage. A regulator generates a pulse width modulation (PWM) signal based on the desired voltage and applies the PWM signal to an alternator.
