PURPOSE:To maintain response characteristic and reduce ripple during drive control operation and to prevent impact upon abrupt brake operation by controlling the integration time constant of an integration circuit according to the opening of an accelerator and controlling the integration circuit such that the integration time constant for full close of the accelerator can be obtained upon full close of the accelerator. CONSTITUTION:An integration time constant control section 12 controls the integration time constant of an integration circuit 9 to increases as the opening of an accelerator decreases. An accelerator full close detecting section 21 controls the integration circuit 9 such that the integration time constant for full close of the accelerator can be obtained upon full close of the accelerator regardless of the operating condition of the integration time constant control section 12. By such arrangement, two contradictory requirements, i.e. retention of response characteristic and reduction of ripple during drive control operation, can be satisfied and impact due to abrupt variation of driving force can be prevented upon abrupt brake operation. |
