Control system for continuously variable transmission in motor vehicle |
摘要 |
In a continuously variable transmission (CVT), the desired engine speed is defined as a function of the throttle position. The speed ratio of the CVT is controlled such that the actual engine speed reaches the desired engine speed. The desired engine speed is set to B (Nos-Nos') upon the abrupt change in the throttle position, where B is a positive value less than 1, Nos is a desired steady-state engine speed after the change and Nos' is a desired steady-state engine speed before the change. Thereafter the desired engine speed approaches gradually the desired steady-state engine speed corresponding to the present throttle position. In the present invention the values of B in acceleration and deceleration of a vehicle are defined different from each other.
