Abstract
An electronic engine-governor control is carried out using no arithmetic tables and thus relieving a load to the CPU. A throttle opening is controlled with a control quantity to suppress a difference between the actual revolutions and the target. Calculator A is provided for calculating the difference D between the current revolutions and the target Ne(tgt). The difference D is corrected with an adjustment A based on a difference between the current revolutions Ne(0) and the previous revolutions Ne(−1)and an adjustment B based on a difference between the previous revolutions Ne(−1) and the revolutions before previous revolutions Ne(−2). Calculator B is provided for calculating an adjustment E in relation to a load from the throttle opening &thgr;TH(0) and the target Ne(tgt). Calculator C is provided for calculating D/E, the throttle controlling signal P&thgr;TH.
