    摘要： The present invention relates to an engine (19) having a premixed combustion mode, an EGR flow rate estimating precision is deteriorated at a transient time, and a torque fluctuation and an exhaust gas deterioration are caused. In an engine control apparatus (8) having a premixed combustion mode (102) and a diffusion combustion mode (101), a sensor (12) detecting an EGR flow rate is arranged in an EGR flow path (9) of the engine (19), and a cylinder state of the engine is estimated by using an output value of the sensor detecting the EGR flow rate at a time when the engine (19) is in the premixed combustion mode (102). Since it is possible to accurately detect the EGR flow rate at the transient time and feed back the EGR flow rate at a high response, it is possible to prevent a torque fluctuation and an exhaust gas deterioration.

    摘要： A first sensor element 100-1 outputs a first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A second sensor element 100-2 outputs a second output signal associated with the first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A first conversion processing section 200-1 converts the first output signal output from the first sensor element 100-1 and the second output signal output from the second sensor element 100-2 into the second physical quantity. A second conversion processing section converts the first output signal output from the first sensor element 100-1 and the second output signal output from the second sensor element 100-2 into a signal representing the rotation angle of the motor.
