Apparatus for controlling continuously variable transmission |
| 摘要 |
A continuously variable transmission (CVT) is controlled such that an actual engine speed Ne is equalized to a desired engine speed Ne'. Defining Nc as a positive constant, the speed ratio e of the CVT is substantially fixed during a period of time when the Ne changes from Ne<Ne'-Nc to Ne'-Nc</=Ne<Ne' and then changes to Ne>/=Ne'. Ne'-Nc is defined as a temporarily desired engine speed during a period of time when the Ne changes from Ne>/=Ne' to Ne'-Nc</=Ne<Ne' and then changes to Ne<Ne'-Nc. During the period of time the speed ratio of the CVT is changed such that the actual engine speed Ne is equalized to the temporarily desired engine speed Ne'-Nc.
