<p>PROBLEM TO BE SOLVED: To improve an initial response of acceleration when a running state is restored to a highμroad from a lowμroad. SOLUTION: When an engine and a continuously variable transmission are controlled by calculating an operational volume required to adjust an acceleration estimation valueαwf to coincide with a target acceleration aαw * through a model following control means which uses a state-space method, the slipping state of a driving wheel is detected(4f) and a state feedback gain is switched coping with the slipping state of the driving wheel, and when the driving wheel changes from a slipping state to a non-slipping state, the initial value of integrated means 4b is reset to 0. Thus, a useless integrated value is reset to 0 even when running is shifted to a highμroad from a lowμroad while the integrated value of the integrated means 4b is increasing on the lowμroad. The responsiveness of controlling amount (such as acceleration, the rotational rate of a primary pulley) after the shift of the highμroad can be improved.</p> |
