PURPOSE: To control driving force which is suited to characteristic of a driver at all times and eliminate regulation for sensibility of a control amount which is not necessary except for an acceleration running time so as to ensure good running feeling at the time of acceleration running.
CONSTITUTION: In a neuro-computer 22, acceleration G is learnt as a teacher data only in the case of starting acceleration from stopping, or accelerating operation such as passing acceleration from normal running and the like and stepping down-acceleration of following acceleration and the like. And the relation of acceleration G between acceleration stroke S and car speed V is learn as a demand acceleration mode. The deviation between output of the demand acceleration model and acceleration G is learn as an error signal, and the relation of throttle opening degree Th between acceleration stroke S and car speed S is learn as a throttle sensibility model. In a throttle computer 21, output of the throttle sensibility model is learned as information data, and a throttle valve 7 is opened/closed according to acceleration stroke S so as to control output of an engine 2.
