Abstract
A powertrain engine control method may include: acquiring period information based on tooth information of an engine crank target wheel by using a timer (T); subdividing the period information by a division rate value (R) by using a timer (D) so as to enable the timer (D) to operate R times; carrying out synchronization with the timer (D) and carrying out counting by using a timer (A) from a zero (0) to 720 degrees for a four-stroke engine operation cycle; and correcting, by using a timer (V), an angle counter which is not generated at the time of deceleration of a vehicle.
Claims10
A powertrain engine control method using an engine controller equipped with a central processing unit including a general purpose timer, the control method comprising:
- acquiring, by a first timer, period information based on tooth information of a crank target wheel;
- subdividing the period information by a division rate value using a second timer so as to enable the second timer to operate times corresponding to the division rate value;
- carrying out synchronization with the second timer and carrying out counting using a third timer from a zero (0) to 720 degrees for a four-stroke engine operation cycle;
- and
- correcting, by a fourth timer, an angle counter which is not generated at a time of deceleration of a vehicle;
- and
- triggering the third timer and the fourth timer by generating an overflow flag, when the second timer reaches a value of zero from a set value.

- correcting, by a fourth timer, an angle counter which is not generated at a time of deceleration of a vehicle;
- setting the fourth timer to a size value at which one tooth is divided;
- and
- when a next tooth signal is input, checking whether the fourth timer carries out counting times corresponding to the size value of the fourth timer.
