Abstract
PURPOSE: To enable to determine specifications of a vehicle without collecting tens of thousand point data, by calculating, from map data of injection timing, the optimal fuel injection timing capable of exerting a required torque ratio that is determined from another map data of torque ratio.
CONSTITUTION: Map data m2 of injection timing based on specific conditions of engine and map data m1 of torque ratio determined from a combination of the engine conditions and the vehicle conditions are stored independently in a memory 14. These data in the memory 14 are combined organically in a theoretical operating unit 10. In case of changing the final speed reduction ratio for improving "drive feeling", it is accomplished only by changing the map data m1, that is, it is not necessary to change map data m2 since the map data m2 is completely independent from map data m1. Therefore, if several kinds of map data m1 are prepared and used in combination with map data m2, an optimal matching can be obtained immediately.
