摘要：
A sensor signal from a speed sensor is inputted into an ECU. The ECU calculates a rotation speed of a crankshaft in a predetermined period based on the sensor signal. The rotation speed is filtered by a frequency which is defined based on a combustion frequency of the engine to obtain a value corresponding to a current torque. The ECU calculates a workload of each cylinder based on the value corresponding to the current torque, and controls characteristic of each cylinder based on the workload.
