Controller for engine having component
First Claim
1. A controller for an engine driving a vehicle and having at least one component, the component driven by an output torque of the engine, comprising:
- a component-drive-torque calculating means for calculating a component-drive-torque which is necessary to achieve a function of the component;
an engine control means for adjusting an engine torque, which represents the output torque of the engine, according to the component-drive-torque; and
a component control means for controlling the component with a delay in consideration of a delay of responsiveness of the engine torque.

Abstract
A required-generate-current (RGC) is calculated according to conditions of the electric loads and a charging state of the battery. The required-alternator-drive-torque (RADT) is estimated according to the required-generate-current (RGC). A required engine torque is calculated by adding the required-alternator-drive-torque (RADT) and the required-vehicle-drive-torque (RVDT) together. The engine torque which is realized at next calculating timing is estimated in consideration of a response delay of the engine. The differential torque between the estimated engine torque and the required-vehicle-drive-torque (RVDT) is calculated as the permission torque. The command current corresponding to the permission torque is calculated. The control current of the alternator is controlled in such a manner as to generate current corresponding to the command current at the next calculating timing.
