Abstract: A power control ECU controls electric power and engine power of a hybrid vehicle. The power control ECU includes a request driving force calculating portion that calculates a request driving force calculated in accordance with an accelerator operation amount, a travel driving force calculating portion that calculates a travel driving force as a value that belatedly follows the request driving force, and a dashpot control processing portion. The dashpot control processing portion sets a value of the request driving force as a value of a final request driving force used to calculate request engine power when a difference of the request driving force with respect to the travel driving force is less than a predetermined positive value, and sets a value that belatedly follows the request driving force when the difference is greater than or equal to the predetermined positive value.

Abstract: A pre-stoppage ignition control unit defines, as a stoppage transition air amount, an intake air amount of the engine with which the engine torque becomes the stoppage transition torque in a state in which an ignition timing of the engine is set to a predetermined self-sustaining operation ignition timing, defines, as an intermediate timing, a predetermined timing earlier than timing at which the intake air amount converges to the stoppage transition air amount during an execution period of the pre-stoppage self-sustaining operation control, sets the ignition timing of the engine in a period from the start of the pre-stoppage self-sustaining operation control to the intermediate timing to timing earlier than the self-sustaining operation ignition timing, and sets the ignition timing of the engine in the period after the intermediate timing to the self-sustaining operation ignition timing.

Abstract: A controller controls an electric motor such that a pulsation compensation torque corresponding to a pulsation component of a torque of an internal combustion engine, which appears in a drive shaft, is supplied to the drive shaft as a damping torque for suppressing vibrations of a hybrid vehicle. A determination is made as to whether a torque of the electric motor, excluding the pulsation compensation torque, is smaller than a predetermined value. When it is determined that the torque excluding the pulsation compensation torque is smaller than the predetermined value, the controller selects one mode having a highest energy efficiency of the hybrid vehicle from among a plurality of modes, and controls the internal combustion engine and the electric motor based on the selected mode.

Abstract: An electronic control unit is mounted on a vehicle including an internal combustion engine and electric motors, each of which is connected to a driving shaft to be capable of transmitting power. The electronic control unit is configured to compute compensation torque reducing a pulsation component of engine torque of the internal combustion engine and command a value in which required torque of the electric motor is combined with the computed compensation torque to the electric motor as a torque command value of the electric motor. The electronic control unit is configured to correct the torque command value so that the value opposite in sign to an average torque command value is not commanded to the electric motor when the average torque command value is smaller than an amplitude of the torque command value.
