<p>PURPOSE:To make it possible to finely correspond to the change of the running condition of the car by calculating the car speed at the speed change point from the accelerator opening degree and the acceleration on the shift pattern curvature of a shift pattern consisting of car speed-accelerator opening degree-acceleration, and comparing the thus calculated car speed with the actual car speed. CONSTITUTION:A shift pattern curved surface defined on the three-dimensional space of car speed-accelerator opening degree-acceleration is selected from a shift pattern selecting part 15, and it is outputted to a speed change point computing part 16. To the speed change point 16 are inputted an accelerator opening degree signal and an acceleration signal. At the speed change point computing part 16 is calculated the car speed at the speed change point is calculated from the accelerator opening degree and the acceleration of the curved surface of the shift pattern selected is compared and discriminated with and from the actual car speed the comparing part 17, and a changeover (speed change) signal is outputted.</p> |
