Abstract (en)
An engine speed control device includes a target engine speed calculation unit that calculates a target engine speed in accordance with an accelerator opening degree of a vehicle, a torque gain calculation unit that calculates a torque gain, on the basis of a change amount of an actual engine speed and an attainment rate of the actual engine speed to the target engine speed, and a system request torque calculation unit that calculates system request torque on the basis of a value obtained by multiplying driver request torque by the torque gain. The system request torque which is calculated in this way is requested to be outputted from an engine of the vehicle, and control of the engine speed is performed.
