Abstract
In a torque control device for an internal combustion engine, a driving-system torque calculation unit calculates a driving-system torque operating on a driving system, based on a requested torque at a time of acceleration. A torque control unit executes torque control so that a gradient of the driving-system torque becomes equal to or smaller than a predetermined value, based on the driving-system torque calculated by the driving-system torque calculation unit. Thereby, since an amount of twist of the driving system can be maintained equal to or smaller than a predetermined value, repetitive shock can be suppressed, and acceleration shock can be effectively suppressed, too. Response deterioration and fuel consumption deterioration at the time of acceleration can be prevented.
Claims7
A torque control device for an internal combustion engine which controls a torque of an internal combustion engine mounted on a vehicle, comprising:
- a driving-system torque calculation unit which calculates a driving-system torque operating on a driving system for transmitting the torque of the internal combustion engine to driving wheels, based on a requested torque at a time of acceleration of the vehicle;
- and
- a torque control unit which controls the torque of the internal combustion engine so that a gradient of the driving-system torque becomes equal to or smaller than a predetermined value, based on the driving-system torque calculated by the driving-system torque calculation unit,
- wherein the driving system is formed by a drive shaft.
