Title: Apparatus for generating speed change control signal for automatic transmission
Inventor: NOMURA KENICHI
Filed: 1983-06-08
Abstract: PURPOSE:To perform the speed change control with high accuracy, by processing a throttle opening detected value outputted from a throttle sensor in a prescribed manner to produce a speed change conrol signal. CONSTITUTION:The output from a throttle sensor 26 is inputted into a fuel jetting control apparatus 40, the throttle opening detected value is corrected at a CPU44 in accodance with prescribed features, and when the corrected throttle opening detected value is within a range defined for the respective throttle opening signals, the respective throttle opening signals are made ON to produce a speed change control signal approximately proportional to the power generated to the engine. Thus, to process the signal, the relationship between the throttle opening and the shaft torque characteristics is made linear, and since the shaft torque would not rise sharply within the range where the throttle opening is small, the speed change control can be made with high accuracy in case the throttle opening in case of a high performance engine is small.
