<p>PROBLEM TO BE SOLVED: To make it possible to accurately estimate MBT ignition timing, and to accurately control an engine torque by using this estimation for an engine torque base control or the like.SOLUTION: An MBT ignition timing computing device comprises: MTB reference value calculation means 121 and 221 calculating a MBT ignition timing reference value SA-MBT on the basis of an engine rotational speed Ne and an engine load Ec; and MBT correction means 125 and 225 correcting the calculated reference value SA-MBT according to an engine temperature TEM of an engine that is an operation state parameter indicating an operation state of the engine and the engine rotational speed Ne. A torque base control is exerted to control ignition timing using this corrected MBT ignition timing SA.</p> |
