PURPOSE:To obtain favorable acceleration even with varying slip ratio by correcting the acceleration with a delay time commensurate with the acceleration, calculating a reference torque based on the corrected acceleration, deducting a torque corresponding to a slip amount, and setting a target torque. CONSTITUTION:The speeds of driven wheels are obtained with sensors 13, 14. The centripetal acceleration GY is obtained through a calculation section 53. The speeds VR of driven wheels are obtained through weighting sections 38, 39 for correcting with a variable Kr commensurate with the GY and through low/high vehicle speed selection sections 36, 38. A reference torque TG is obtained with a calculating section 47c through a filter 47b for switching delay time according to the condition of the driven wheel acceleration GB. The drive wheel speeds according to sensors 11, 12 are obtained through a high vehicle speed selection section 31, an averaging section 32, and weighting sections 33, 34 of a variable KG commensurate with the GY. A slip amount is obtained from a difference between the drive wheel speed and a target drive wheel speed Vphi. A correction torque is calculated with operation sections 45, 46. The correction torque is deducted from the reference torque TG to set a target engine torque. A favorable acceleration is attained in this way. |
