PURPOSE:To prevent a shift between the points for speed change and for lock-up, by rewriting the content of a memory means every time when new voltage data are input in order to absorb the fluctuation of the relationship between the opening of a throttle opening sensor and an output voltage characteristic. CONSTITUTION:In the memory 22 of an electronic control device 11, voltage data corresponding to 0% and 100% throttle openings are stored so as to make a computing unit 21 calculate the throttle openings are stored so as to make a computing unit 21 calculates the throttle opening corresponding to any given voltage value on the basis of voltage data with 0% and 100% openings. When a new value is detected as a value for 0% or 100% opening, a process is taken to rewrite the content of said memory 22. Accordingly, because the throttle openings for detected voltage data are calculates and the possible fluctuation is absorbed, after the voltage value for 0% or 100% opening is newly rewritten in the memory, the shift of the points of speed change and lock-up can be prevented. |
