Throttle-valve opening degree control for automatic step-wise transmission system |
摘要 |
To control an automatic step-wise transmission system of a vehicle including a vehicle engine, the controlling steps include: acquiring real throttle-valve opening degree data of the vehicle engine; checking whether or not conditions of the vehicle engine are in a start-up status when the real throttle-valve opening degree data is acquired; calculating a difference between the real throttle-valve opening degree data acquired during the determination of the start-up status and reference throttle-valve opening degree data previously stored so as to obtain a correction value for the real throttle-valve opening degree data; correcting the real throttle-valve opening degree data based upon the correction value to produce controlling throttle-valve opening degree data; and, controlling the automatic step-wise transmission system based upon the controlling throttle-valve opening degree data so as to perform a gear-changing operation of the vehicle engine.
