PURPOSE: To prevent inconvenience from being generated on the annealing treatment of data even if the speed is changed from the not-set speed change stage to the set speed change stage as well as to reduce the capacity of a ROM by limiting the speed change stage wherein the reference acceleration data is prepared to the indispensable speed change stage. CONSTITUTION: In a system wherein the reference vehicle acceleration is previously stored on the basis of the vehicle speed, the throttle opening, and the speed change stage, and the uphill road is judged by comparing it with the actual vehicle acceleration, the speed change stage wherein the data of the reference vehicle acceleration is prepared is limited to the indispensable speed change stage, and the capacity of a ROM is reduced, and the data is filter-processed and used, and the sudden change possibility of the throttle opening and the responsiveness to the change of the reference vehicle acceleration are matched to each other. In this case, the filter-processing is temporarily prohibited when the speed is changed from the speed change stage wherein the data is not set to the speed change stage in which the data is set, and the raw value itself of the data is used as the (filter-processed) reference acceleration, and the filter-processing is restarted on the basis of this value. |
