Abstract
A method and apparatus for controlling part load mode engine torque are provided. The method includes setting a limitation of part load mode engine torque based on a current traveling environment and calculating a first engine torque variation in the basis of state information of a battery. When the first engine torque variation is calculated, a second engine torque variation is calculated based on a measured engine error amount. The limitation of part load mode engine torque is compensated based on the calculated first and second engine torque variations.
Claims14
A method of controlling part load mode engine torque, comprising:
- setting, by a controller, a limitation of part load mode engine torque based on a current traveling environment;
- calculating, by the controller, a first engine torque variation based on state information of a battery;
- when the first engine torque variation is calculated, calculating, by the controller, a second engine torque variation based on a measured engine error amount;
- and
- compensating, by the controller, the limitation of part load mode engine torque based on the calculated first and second engine torque variations.
An apparatus for controlling part load mode engine torque for a hybrid vehicle, comprising:
- a demand torque calculation unit configured to calculate a limitation of part load mode engine torque, based on a vehicle driving environment;
- a torque compensation unit configured to compensate the limitation of part load mode engine torque by calculating a first engine torque variation based on state information of a battery and calculate a second engine torque variation based on an engine error amount;
- and
- an engine controller configured to set the limitation of part load mode engine torque compensated based on the calculated first and second torque variations as a limitation of engine drive torque to drive an engine of the vehicle.
