<p>PURPOSE:To reduce a speed change shock by carrying out feedback control of driving shaft torque without using an expensive torque sensor. CONSTITUTION:A driving shaft torque calculating part 10 to find driving shaft torque Td from the number Ne of revolutions of an engine, throttle opening (theta) and the number Nd of revolutions of a driving shaft, a torque control period setting part 9 to set a driving shaft torque control period at speed change time and a target driving shaft torque setting part 11 to determine target driving shaft torque Ta in a torque control period, are provided. A torque deviation operation part 12 to find deviation (d) between the target driving shaft torque Ta and the driving shaft torque Td found by the driving shaft torque calculating part 10 and an engine control part 7 to change engine torque by controlling the ignition timing so as to eliminate this deviation (d), are also provided.</p> |
