Abstract
A method of controlling a generated power in a series hybrid vehicle. From the tendency of an inverter input power or a motor dissipation power in a certain period is first estimated the tendency of the inverter input power or the motor dissipation power in the next period. The target power to be generated is then set on the basis of the results of the estimation. Alternatively the target power to be generated is corrected in accordance with the quantities such as an accelerator angle indicating the load of the motor or a battery current indicating the state of charge/discharge of the battery. Alternatively that period is compulsorily interrupted to start the next period. This will eliminate a delay arising from averaging the inverter input powers or the motor dissipation powers for use as the target power in the next period, thus resulting in improved vehicle power efficiency and drive feeling.
