Abstract: A control apparatus of a hybrid vehicle has an abnormal sound generation condition determination unit that determines whether or not an abnormal sound generation condition of a gear train is satisfied, and a pressing processor that applies a pressing torque from a first rotary electric machine to the gear train when a retention time, which is a period in which the abnormal sound generation condition continues to be satisfied, exceeds a predetermined value, and that does not apply the pressing torque when the abnormal sound generation condition is not satisfied and when the retention time is within the predetermined value. A pressing torque setting unit sets a pressing torque to be applied by the first rotary electric machine to a direction to suppress an engine cam torque which may rotate an engine output shaft.

Abstract: In the case of motoring an engine by a first motor in reverse driving (S120, S130), a rate of increase Rup is set to provide a larger value at a lower required torque Tr* (larger absolute value) than a value at a higher required torque Tr* (smaller absolute value) (S180). A target rotation speed Ne* of the engine is increased by using the set rate of increase Rup (S190). The first motor is controlled to make rotation speed. Ne of the engine equal to the target rotation speed Ne* (S200, S210 and S240).

Abstract: A control apparatus of a hybrid vehicle has an abnormal sound generation condition determination unit that determines whether or not a drive state of the hybrid vehicle satisfies an abnormal sound generation condition of a gear train, and a pressing processor that executes a pressing process to apply a pressing torque to suppress generation of abnormal sound from a first rotary electric machine to the gear train of a transmission mechanism when the abnormal sound generation condition is satisfied and to not apply the pressing torque when the abnormal sound generation condition is not satisfied. A pressing torque setting unit sets a pressing torque to be applied by the first rotary electric machine to a torque in a direction to suppress an engine cam torque that may rotate an engine output shaft during a period in which the engine is stopped.

Abstract: In a manual transmission mode, a downshift instruction signal is outputted by a position sensor, and a shift range is lowered by one gear, as a result of an operation of a shift lever by the driver. The driving force of the vehicle is increased through downshifting. The number of times of downshifting within a predefined time is limited to a predefined number of times.

Abstract: A control device of a hybrid vehicle is configured to control an engine and a motor such that a battery is charged or discharged and the hybrid vehicle travels on drive power. The control device is configured to execute discharge-oriented control when a temperature of a purification catalyst is higher than or equal to a predetermined temperature. In the discharge-oriented control, the engine and the motor are controlled such that a charging and discharging electric power of the battery increases toward a discharging side when the temperature of the purification catalyst is higher than or equal to the predetermined temperature as compared to when the temperature of the purification catalyst is lower than the predetermined temperature. The predetermined temperature is lower than a degradation promoting lower limit temperature. Stated differently, engine output is reduced to avoid damaging the catalyst.

Abstract: At or before time t2 when a kick-down switch was off, the higher speed a shift ratio selected by a driver is for, the smaller value a restriction rate K is set to. Consequently, driving force in a Mid-gear ratio is more restricted than driving force in a Lo-gear ratio. Further, driving force in a Hi-gear ratio is more restricted than driving force in the Mid-gear ratio. At time t2 when the kick-down switch changes from off to on, the restriction on driving force employing a restriction rate K is removed, whereupon an increment ? in driving force in the Hi-gear ratio is, as it had a greater restricted amount during KD OFF, greater than an increment ? in driving force in the Mid-gear ratio. A natural kick-down feeling responsive to the selected shift ratio is thus realized.

Abstract: The drive control of the invention adopted in a hybrid vehicle specifies an operation line L to give a greater torque in a low rotation speed area of an engine with an increase in vehicle speed and controls the operation of the engine according to the specified operation line L. The engine can thus be driven at a higher-efficiency drive point, while the driving-related background noise effectively masks some abnormal noise or muffled noise, which may be caused by the operation of the engine in a low rotation speed-high torque area. This arrangement desirably prevents the driver and the other passenger from feeling odd and uncomfortable due to the abnormal noise or muffled noise and enhances the energy efficiency of the hybrid vehicle.
