    摘要： A control system (100) includes a first control device (110) and a second control device (120). The second control device (120) transmits, to the first control device (110), a resonance influence torque (Tdmp) or a first motor rotation angle speed (ωmg1), and information acquisition timing (TMd), which is an acquisition timing of the first motor rotation angle speed (ωmg1). The first control device (110) calculates an engine inertia torque (Tei) based on an engine rotation angle speed (ωe). The first control device (110) selects the resonance influence torque (Tdmp) based on the first motor rotation angle speed (ωmg1) acquired at a predetermined derivation timing (TMa), based on the received information acquisition timing (TMd), and derives, as an engine torque (Te), a sum of the resonance influence torque (Tdmp) and the engine inertia torque (Tei), calculated based on the engine rotation angle speed (ωe) derived at the predetermined derivation timing (TMa).

    摘要： [Problem]
    To provide an engine unit including a misfire detection device and an internal combustion engine capable of enhancing a misfire detection accuracy at a time of a high load and a high rotation speed while maintaining a misfire detection accuracy at a time of a low load and a low rotation speed, based on a crankshaft rotation speed fluctuation.
    [Solution]
    An engine unit provided in a vehicle includes an internal combustion engine and a misfire detection device. The internal combustion engine is configured such that: an interval between adjacent tails of a distribution of a crankshaft rotation speed fluctuation amount under a normal state and a distribution of a crankshaft rotation speed fluctuation amount in a case of a misfire occurring tends to widen as a load increases and to narrow as a crankshaft rotation speed increases; and a low load and low rotation speed region in which the interval between the adjacent tails is relatively narrow and a high load and high rotation speed region in which the interval between the adjacent tails is relatively wide are present in a range of the crankshaft rotation speed and the load during traveling of the vehicle. The misfire detection device further includes a rough road traveling determination unit that: (a) determines a rough road traveling state based on a distribution state of a crankshaft rotation speed fluctuation physical quantity acquired by a crankshaft rotation speed fluctuation physical quantity acquisition unit, or (b) includes a vehicle traveling state detection unit for detecting a physical quantity in relation to a vehicle traveling state except the crankshaft rotation speed fluctuation physical quantity, and determines a rough road traveling state based on a detection result obtained by the vehicle traveling stats detection unit; and suspends a determination of a misfire in the internal combustion engine based on a determination result obtained by the rough road traveling determination unit, at least in the low load and low rotation speed region having a narrower interval between the adjacent tails as compared to the high load and high rotation speed region.

    摘要： The internal combustion engine system of the invention calculates a time constant T of a high pass filter for eliminating a resonance component of a damper as a distortional element from a rotation speed Ne of an engine, and sets the high pass filter with computation of a transfer function from the time constant T (steps S110 and S120). The set high pass filter is applied to a 30-degree rotation time T30 representing a rotational variation of the engine to obtain a filtered 30-degree rotation time F30 with elimination of the resonance component of the damper 28 (step S130). The occurrence of an engine misfire is detected, based on a 30-degree rotation time difference D30 and a misfire detection base difference J30 computed from the filtered 30-degree rotation times F30 (step S140). This arrangement ensures highly-accurate detection of the occurrence of a misfire in the engine constructed to output power via the damper as the distortional element, irrespective of the rotation speed Ne of the engine.
