Abstract
An ECU executes a program including the steps of: detecting engine speed NE based on a signal transmitted from an engine speed sensor; calculating engine speed NE with dead time of the engine with respect to a target output torque removed; calculating engine speed NE reflecting the dead time of the engine with respect to the target output torque; correcting the actual engine speed NE in accordance with a difference between the engine speed with dead time removed and the engine speed reflecting the dead time; and setting the target value of output torque in accordance with the corrected engine speed NE.
Claims12
A controller for a driving source, comprising:
- a speed sensor for detecting an actual first output shaft speed of the driving source;
- and
- a control unit;
- said control unit
- controlling said driving source such that a difference between an actual output torque of said driving source and a target value of output torque of said driving source becomes smaller,
- calculating a second output shaft speed with dead time of said driving source with respect to the target value removed, from said target value,
- calculating a third output shaft speed reflecting the dead time of said driving source with respect to the target value, from said target value,
- correcting said detected first output shaft speed, in accordance with a difference between said second output shaft speed and said third output shaft speed, and
- setting the target value of output torque of said driving source, in accordance with said corrected first output shaft speed.
A method of controlling a driving source, comprising the steps of:
- detecting an actual first output shaft speed of the driving source;
- controlling said driving source such that a difference between an actual output torque of said driving source and a target value of output torque of said driving source becomes smaller;
- calculating a second output shaft speed with dead time of said driving source with respect to the target value removed, from said target value;
- calculating a third output shaft speed reflecting the dead time of said driving source with respect to the target value, from said target value;
- correcting said detected first output shaft speed, in accordance with a difference between said second output shaft speed and said third output shaft speed;
- and
- setting the target value of output torque of said driving source, in accordance with said corrected first output shaft speed.
A controller for a driving source, comprising:
- means for detecting an actual first output shaft speed of the driving source;
- means for controlling said driving source such that a difference between an actual output torque of said driving source and a target value of output torque of said driving source becomes smaller;
